Nitroglycerin Toxicology Assessment Human Toxicity Sources of nitroglycerin exposure range from clinical usage as a coronary vasodilator, occupational exposure through inhalation and dermal contact, and as an environmental contaminant from military use or in wastewater discharges from commercial manufactures of dynamite. The National Institute for Occupational Safety and Health NIOSH ; reported approximately 250 million pounds of dynamite were produced by US manufacturers in 1976, with estimates of 8, 000 people being exposed to nitroglycerin by inhalation and dermal absorption USDHEW, 1978 ; . Human toxicity studies have been conducted primarily for medicinal purposes and occupational health. Common symptoms of human nitroglycerin exposure include headaches, dizziness, rapid pulse rate and respiratory distress. Severe cases report circulatory collapse, convulsions and death due to respiratory failure. A study at Badger Army Ammunition Plant reported 12% of 266 potentially exposed workers suffered symptoms due to nitroglycerin exposure USDHEW, 1987 ; . Air sampling at Radford Army Ammunition Plant concluded that nearly all sampled areas had nitroglycerin concentration exceeding the occupational safety levels of 0.2 ppm USDHEW, 1987 ; . The term "dynamite headache" was used to describe the violent throbbing pain produced by sudden reduction in blood pressure when exposed to nitroglycerin. After repeated exposures, workers tended to develop a tolerance to nitroglycerin and showed no symptoms. However, sudden severe symptoms developed upon re-exposure. This condition was termed "Monday Disease", due to workers experiencing this after a weekend away from the plant. Mammalian and Aquatic Toxicity Whereas thorough toxicology information is available on human toxicity to NG as medicinal product and in industrial environments, information regarding NG toxicity in other areas is sporadic. No teratogenic effects were noted in pregnant rabbits intravenously administered daily doses of nitroglycerin Oketani et al., 1981 ; . Genetic material did not seem to be affected in studies using in vivo and in vitro mammalian and bacterial cell systems Lee et al., 1976 ; or in rats administered NG in feed Ellis, 1978a, b ; , but weak mutagenic activity was noted in Ames assays Ellis, 1978c ; . Reproductive material was affected by formation of carcinogenic tumors of the testes in lifetime feeding studies using rats Ellis et al., 1978a, 1984 ; , while Takayamam 1975 ; reported no reproductive abnormalities in rats and formation of non-carcinogenic tumors in mice subjected to NG contaminated drinking solutions. The available data lacks conclusive confidence as to the toxicological effects of NG. Methemoglobin formation was a common condition found in nitroglycerin exposed test subjects. This condition prevents hemoglobin in red blood cells from carrying and delivering adequate amounts of oxygen to tissues throughout the body. Dogs dosed with daily nitroglycerin concentrations reached peak methemoglobin levels within 1-4 hours Lee et al., 1976 ; . Methemoglobin levels disappeared from the blood within 8-24 hours after dosing. The lack of oxygen to tissues can be observed by cyanosis, a slate gray to bluish discoloration in tissues.

Effects of Levarterenol Infusion and Nitroblycerin on the Levarterenol Response. Isometric Tension Measured ut a Fixed Initial Length and Initial Tension.
Drug Interactions: In one survey, 2.3% of patients taking labetalol HCl in combination with tricyclic antidepressants experienced tremor, as compared to 0.7% reported to occur with labetalol HCl alone. The contribution of each of the treatments to this adverse reaction is unknown, but the possibility of a drug interaction cannot be excluded. Drugs possessing beta-blocking properties can blunt the bronchodilator effect of beta-receptor agonist drugs in patients with bronchospasm; therefore, doses greater than the normal antiasthmatic dose of beta-agonist bronchodilator drugs may be required. Cimetidine has been shown to increase the bioavailability of labetalol HCl. Since this could be explained either by enhanced absorption or by an alteration of hepatic metabolism of labetalol HCl, special care should be used in establishing the dose required for blood pressure control in such patients. Synergism has been shown between halothane anesthesia and intravenously administered labetalol HCl. During controlled hypotensive anesthesia using labetalol HCl in association with halothane, high concentrations 3% or above ; of halothane should not be used because the degree of hypotension will be increased and because of the possibility of a large reduction in cardiac output and an increase in central venous pressure. The anesthesiologist should be informed when a patient is receiving labetalol HCl. Labetalol HCl blunts the reflex tachycardia produced by nitroglycerin without preventing its hypotensive effect. If labetalol HCl is used with nitroglycerin in patients with angina pectoris, additional antihypertensive effects may occur. Care should be taken if labetalol is used concomitantly with calcium antagonists of the verapamil type. Both digitalis glycosides and beta-blockers slow atrioventricular conduction and decrease heart rate. Concomitant use can increase the risk of bradycardia. Risk of Anaphylactic Reaction: While taking beta-blockers, patients with a history of severe anaphylactic reaction to a variety of allergens may be more reactive to repeated challenge, either accidental, diagnostic, or therapeutic. Such patients may be unresponsive to the usual doses of epinephrine used to treat allergic reaction. Drug Laboratory Test Interactions: The presence of labetalol metabolites in the urine may result in falsely elevated levels of urinary catecholamines, metanephrine, normetanephrine, and vanillylmandelic acid when measured by fluorimetric or photometric methods. In screening patients suspected of having a pheochromocytoma and being treated with labetalol HCl, a specific method, such as a high performance liquid chromatographic assay with solid phase and furosemide.

Mechanism of Action Both CSA and TAC act by blocking calcium-activated calcineurin the Figure ; .22, 23 CSA and TAC enter the cell primarily through diffusion and bind to different immunophilins: CSA to cyclophilin and TAC to FK binding protein 12 FKBP-12 ; . The complex of drug and immunophilin binds to calcineurin, a phosphatase that dephosphorylates multiple molecules, including NF-AT NF of activated T cells ; . Dephosphorylated NF-AT translocates to the nucleus, where it binds to specific DNA sites in the promoter regions of several cytokine genes, including interleukin IL ; -2. Thus, both CSA and TAC inhibit transcription of IL-2 and other cytokines.24 CSA also stimulates transforming growth factor- production, which contributes to its immunosuppressive activity.25.

Simon Collins, HIV i-Base In a cross-over study, for the first two weeks of treatment, 37 patients were randomised to start T-20 plus optimised background regimen, using T-20 either once- or twice-daily for the first 7 days and switching to the alternative dose for days 8-14. Oncedaily dose involved taking two 90mg doses in the morning and twice-daily doses involved each 90mg dose taken 12 hours apart. PK was measured on days 6, 7, 13 and 14. More intensive PK at steady stead was measured at 0, 1, 2, 4, on days 7 and 14. Total exposure AUC ; to T-20 and rate of clearance was similar in both schedules. While C max was approximately double when administered once-daily, C trough was also 57% lower than the BID level, and 40% of patients on the once-daily schedule had C tough levels below the target of 1.0ug ml. As resistance to T-20 is related to C trough, and patients using this drug are already dependent on achieving maximum response, this is a significant concern. Linear regression analysis also suggested that viral response was related to C trough and not AUC or C max. Tolerability was similar in once- and twice-daily arms and avalide.

OBJECTIVES: This study was designed to evaluate whether the addition of transdermal nitroglycerin or oral N-acetylcysteine, or both, to conventional medical therapy improves the natural history of unstable angina pectoris. BACKGROUND: Transdermal nitroglycerin is widely used to treat angina pectoris, but the development of tolerance is a major problem that may reduce its clinical efficacy. It has been suggested that the addition of N-acetylcysteine to nitroglycerin reverses the development of tolerance, potentiates the hemodynamic response to nitroglycerin and may improve in-hospital prognosis in unstable angina. METHODS: We assessed the efficacy of adding transdermal nitroglycerin or oral N-acetylcysteine, or both, to conventional medical therapy in a randomized, double-blind, placebo-controlled trial involving 200 patients with unstable angina who were followed up for 4 months. RESULTS: Outcome events--death, myocardial infarction or refractory angina requiring revascularization--occurred in 31% of patients receiving nitroglycerin, 42% of those receiving N-acetylcysteine, 13% of those receiving nitroglycerin plus N-acetylcysteine and 39% of those receiving placebo p 0.0052 ; . Kaplan-Meier curves showed a higher probability p 0.01 ; of no failure of medical treatment in the group receiving both nitroglycerin and N-acetylcysteine than in those receiving placebo, N-acetylcysteine or nitroglycerin alone. The combination of nitroglycerin and N-acetylcysteine was associated with a high incidence of side effects 35% ; , mainly intolerable headache, which was almost twice as frequent as in patients receiving nitroglycerin alone. CONCLUSIONS: The combination of nitroglycerin and N-acetylcysteine, associated with conventional medical therapy in the long-term treatment of patients with unstable angina, reduces the occurrence of outcome events. However, the high incidence of side effects limits the clinical applicability of this therapeutic strategy at least at the dosage used in the present study and hydrochlorothiazide.
Perreault S, Dragomir A, Blais L, Lalonde L, Berard A, Pilon D University of Montreal and University of Sherbrooke, Montreal, Canada Corresponding Author: sylvie.perreault umontreal Funding Source: CIHR Background Aim: Despite evidence that the control of blood pressure may reduce morbidity and cardiovascular mortality, there is high proportion of hypertensive patients whose blood pressure is not controlled. Non-adherence to AH is a major issue in health care and may have a significant negative consequences on clinical outcome. The consequences of non-adherence on the real-life efficacy of drugs needs more study. Objective: To evaluate the impact of AH adherence on the rate of heart failure. Methods: A cohort of 34, 608 patients was reconstructed using the RAMQ databases. All patients aged from 45 to 75 years old who were newly treated with AH agents between 1999 and 2000 were eligible. A nested case-control design was used. Every case of heart failure was matched for age and period with 15 controls. Adherence level was reported as the percentage of the prescribed doses of AH used during follow-up period, and was classified as equal or more than 80% or 80%. Conditional logistic regression models were used to estimate the rate ratio RR ; of heart failure adjusting for several covariables. Results: The overall rate of heart failure was at 2.8%. Among patients followed up for more than one year, those with adherence level of equal or more than 80% had less heart failure RR: 0.59; 0.46-0.76 ; . Patients with diabetes RR: 2.05; 1.53-2.75 ; and higher chronic disease score RR: 2.76; 2.12-3.60 ; had a significantly higher risk of heart failure. Conclusion: This analysis indicates that adherence of equal or more than 80% for more than one year is essential to reduce heart failure among patients in primary prevention. Our results confirm the importance of a long term therapy with AH agents. Keywords: Adherence, antihypertensive agents, heart failure.

Myo-inositol is an important constituent of the phospholipids that make up nerve cell membranes. Because low nerve myo-inositol levels have been observed in the pathogenesis of diabetic neuropathy, the potential for supplementation has been explored. In an animal model of experimental diabetic neuropathy, nerve myo-inositol levels were diminished, with subsequent decreases in Na + -ATPase activity and NCV by 25-30% ; , axonal atrophy, and demyelination; dietary myo-inositol prevented these signs of nerve degeneration.157 In another animal model, experimental diabetes induced a decrease in motor NCV. Supplementation of 500 mg myo-inositol rat day partially prevented this decrease, while supplementation with an analogue of myo-inositol D-myo-inositol-1, 2, 6-trisphosphate at a dose of 24 mg rat day completely prevented a reduction in nerve conduction velocity.158 Sural nerve biopsies were conducted on 30 male subjects 10 with type 1 diabetes five with clinical signs of diabetic neuropathy ; , 10 with impaired glucose tolerance, and 10 with normal glucose tolerance. Nerve myo-inositol levels were significantly lower in diabetics with neuropathy. Also, in subjects with normal or impaired glucose tolerance, high nerve myo-inositol levels were associated with nerve regeneration as illustrated by increased nerve fiber density.159 Despite myo-inositol's potential to prevent or reverse the signs and symptoms of diabetic PN, clinical evidence has been limited. In a small, double-blind, placebo-controlled, crossover trial, seven subjects with clinical signs of neuropathy n 3 ; or subclinical neurophysiological signs n 4 ; were and betapace.

An 18-year-old radio operator with 6 months service was evacuated to Walter Reed Army Medical Center from Germany because of difficulty in articulation. He spoke in garbled fashion clicking his tongue against the roof of his mouth. The symptom had come on the day after receiving a painful novocaine dental injection and had gotten worse over the next 2 months. The soldier was from a rural Southern area and had had 4 years of high school. Under Sodium Amytal he became very drowsy but recovered to speak understandably. He told of his dissatisfaction with his job, the shock of seeing black men with white women. He described how upset he was when he found that the dentist was a black woman. He went on to say how worried he was about his mother, who had no one to take care of her. She had told him that she, too, had a burning in her mouth after dental work. He was vague about his father who, he said, had been killed by the Mafia. He, himself, had almost been killed in an accident but had been saved by a miracle. The patient spoke normally but the following day had relapsed halfway. Following a leave home, he talked normally. A psychiatric evaluation noted dependent and avoidant personality traits and he was not returned to overseas duty. Comment: The case illustrates how, under the conditions of brain function supplied by a barbiturate, the soldier could restructure the problems of job inadequacy and homesickness in metaphors of race, violence, and filial devotion and benicar.

A comparison of a large set of widely available off-patent products displayed much different results. The average prices foreigners pay for generics are more than 50% greater than average prices Americans pay, with the exception of one country Poland ; included in the study. The HHS Task Force estimated that about 30% of total drug spending may be unchanged by legalizing commercial importation of drugs because many pharmaceuticals are inappropriate for importation e.g., injectables, biologics, some inhalants, and controlled substances ; or cost more in most foreign countries e.g., generics ; . Although different criteria were used, a 1999 study conducted by Patricia M. Danzon and Michael F. Furukawa involving prices and availability of pharmaceuticals in nine countries revealed similar findings. The study's overall price indexes showed that Japan's prices were higher than US prices, with all other countries' prices ranging from 6% to 33% lower--Canada being the lowest. Exhibit 4 displays the findings of a comparison of manufacturer prices for single-source originator on-patent ; products a proxy for single-source brands ; and generics in 1999. Japan had the highest price for onpatent products and generics. All other countries in the study had lower prices than the United States for single-source originator products. Generic prices were found to be lower in the United States than in all other nations except Canada. In addition, the Danzon and Furukawa data strongly suggested that over-the and florinef.

OBJECTIVES: This study sought to examine the effects of long-term estrogen therapy on vascular function in male to female transsexuals and to compare the findings with those observed in men and premenopausal women. BACKGROUND: Gender differences in coronary artery disease have largely been attributed to the beneficial effects of estrogen on vascular function and plasma lipids in women. However, the effects of estrogen on the male vasculature have not been widely studied. METHODS: We compared the effects of estrogen on vascular function in 14 male to female transsexuals, 14 age-matched men and 15 premenopausal women. Flow-mediated vasodilation and response to nitroglycerin were assessed in the brachial artery using noninvasive ultrasound. RESULTS: Flow-mediated vasodilation was similar in transsexuals and women but greater than that in men [mean + - SE] 11.5 + - 1.3% and 9.4 + - 1.1% vs. 5.2 + - 1.0% respectively, p 0.005 ; . Responses to nitroglycerin were also greater in transsexuals and women than in men 21.6 + - 1.7% and 21.0 + 0.9% vs. 14.5 + - 1.2%, respectively, p 0.0005 ; . These differences persisted even after adjusting for vessel size. Despite similar total cholesterol levels, transsexuals had high density lipoprotein cholesterol levels similar to those in women and greater than those observed in men 1.76 + - 0.12 and 1.82 + - 0.11 mmol liter vs. 1.35 + - 0.07 mmol liter, respectively, p 0.005 ; . Moreover, triglyceride levels were greater in transsexuals than in men and women, and low density lipoprotein cholesterol LDL-C ; particle size was smaller 25.7 + - 0.2 nm vs. 26.2 + - 0.1 and 26.6 + - 0.1 nm, respectively, p 0.0001 ; . Serum testosterone an index of estrogen therapy in transsexuals ; was markedly suppressed in transsexuals and similar to that in women. Univariate analysis revealed that there was a strong inverse correlation between serum testosterone and flow-mediated vasodilation r s ; -0.48, p 0.005 ; . Multivariate analysis revealed that the best combination of predictors of flow-mediated vasodilation was serum testosterone, vessel size and LDL-C R2 0.3, p 0.005 ; . CONCLUSIONS: Long-term estrogen therapy appears to improve vascular function in male to female transsexuals and occurs despite higher triglyceride levels and the presence of small, dense LDL-C. The beneficial effects of estrogen are not gender specific or solely mediated through endothelium-derived nitric oxide.

Introduction: Some stroke patients were free of any stroke risk factors. The pathogenesis of stroke in these patients was not well known. We proposed endothelium dysfunction might be important in these patients and conducted this study . Method: We evaluated flow-mediated endothelium-dependent ; dilation of brachial artery and nitroglycerin-induced endothelium independent ; dilation of brachial and carotid artery in all study subjects. High-resolution ultrasound was used to measure changes in artery diameter. Twenty-five stroke patients and 25 healthy volunteers were recruited for the study. All stroke patients had no hypertension, DM, hyperlipidemia or heart diseases. Non-parametric t-test was used for statistic analysis. Result: The stroke patients had significant less maximal percentage endothelium-dependent dilation 3.88% -1.30%SEM vs. 10.14% -1.18%, p 0.002 ; and diameter changes 0.179 -0.059mmSEM vs. 0.398 -0.047mm, p 0.03 ; . Nitroglycerin-induced dilation of brachial artery was significantly different between stroke and control group at 5 9.37% 1.97% vs. 18.99% -3.40%, p 0.018 ; and 10 minutes 5.26% -3.00% vs.16.26% 2.44%, p 0.002 ; after nitroglycerine was given sublingually. Sublingual NTG induced more immediate at 1 minute ; carotid artery dilation in stroke subjects 4.61% -1.63% vs. 1.66% -0.97%, p 0.134 ; , although the difference did not reach statistic significance. After correction of age, sex and baseline brachial artery diameter, the endothelium-dependent dilation of brachial artery was still significant different between both groups. Conclusion: Our findings demonstrated flow-mediated dilation was impaired in stroke patients without stroke risk factors. Endothelial dysfunction might be an independent risk factor of stroke in some patients. The vasodilation effect of nitroglycerin was less durable in stroke patients. Nitroglyccerin elicited more early carotid artery dilation probably due to denervation hypersensitivity of smooth muscles in diseased artery.
Objective: determine safety, tolerance, pharmacokinetic features, hemodynamic and cardiac metabolic effects of ranolazine 200 g kg in patients with ischemic heart disease undergoing atrial pacing. Study Summary: This was a single-dose, single-blind study. Males with a clinical diagnosis of angina received a saline injection first, followed by administration of intravenous ranolazine 200 g kg. Prior to and 20 minutes after saline and 20 minutes after ranolazine dosing the patient was to undergo atrial pacing. The effect of the compound will be assessed by measurements of: coronary sinus blood flow, coronary sinus oxygen, lactate and pyruvate content, systemic arterial oxygen, lactate and pyruvate content, time to pacing-induced angina, BP HR. If a coronary sinus catheter could not be successfully inserted, then a pacing wire would be inserted and only BP, HR and time to pacing-induced angina would be measured. In addition, symptoms ECGs would be monitored, and blood for pharmacokinetic analysis safety screened were to be obtained. Study Population: Males, 21-75 years, undergoing cardiac catheterization or atrial pacing test, with a clinical diagnosis of angina based on a positive exercise test or history of MI. Patients must not have received cardiac drugs for one week prior to the study, except for: calcium blockers beta blockers up to 48 hours prior to the study; long-acting nitrates up to 12 hours prior to the study; sublingual nitroglycerin up to 2 hours before the study. Notable Exclusions: Please see Study RAN 003 identical exclusions ; . Procedures: Atrial pacing: Atrial pacing was performed pre- and 20 minutes post-saline and 20 minutes post-active dosing. Starting at 100 beats per minute the rate was to be increased gradually by 10 beats minute and each rate held for 3 minutes. The criteria for discontinuation was: chest pain or 1 mm depression below resting; upsloping ST depression was to be measured 0.08 seconds after the J point. Coronary sinus CS ; blood flow: This parameter was measured using a continuous thermodilution technique. During the third minute at each level of pacing CS flow will be calculated 3-4 times over consecutive 10-15 second intervals. The recorded flow values on the case report form will represent the average of measurements obtained over the one minute interval. CS flow will also be measured in a similar manner before the start of pacing baseline ; and during the 5 minutes after pacing has stopped. Blood samples for myocardial oxygen uptake, pyruvate levels and % lactate extraction will be obtained from the arterial catheter and CS during the 3 rd minute but 15-30 seconds after each flow measurement. Hemodynamic data: Blood pressure was obtained by sphygmomanometry. Duplicate recording was planned at each time point. Hemodynamic measurements were planned during the 3 rd minute at each level of pacing; in addition, values would be obtained before pacing baseline ; and during the 5 minutes after pacing. Central hemodynamic measurements would be obtained by averaging the values from at least 5 consecutive heart beats. ECG: Six-lead ECGs were obtained prior to, catheterization; at least two leads will be continuously monitored throught the study. A 6-lead ECG will be recorded within 1-4 hours after the procedure, and a 12-lead ECG will be obtained on the morning following catheterization. Angiographic data: Left ventriculography and coronary angiography were to be performed in the usual manner, if clinically indication, after the completion of post-dosing hemodynamic measurements. The findings were to be recorded in the case report form. Pharmacokinetic sampling: Venous blood samples were to be taken prior to ranolazine dosing, 2, 5, 10 and 20 minutes after dosing, and immediately and 5 minutes after completion of post-drug pacing measurements.

Determined in the presence of the identical amount of SHP in cells treated with ethanol EtOH ; . In this way, any SHP-induced alteration in basal activity was eliminated from our assessment of SHP's effects on E2 or 4-OHT activity. The EREc38 and pS2 ERE-luciferase reporters have been described 25, 34 ; . Some cells were cotransfected with the coactivators pSCT-SRA2 and or pSG5.HA-protein arginine methyltransferase 1 PRMT1 ; , which were graciously provided by Dr. Bert W. O'Malley 35 ; and Dr. Michael R. Stallcup 36 ; , respectively. As with SHP, any effects of steroid receptor coactivator SRA ; and PRMT1 on basal EtOH ; activity were used to normalize the data for cells treated with ligand. One hour after transfection, 20% CCS, 2% pen strep IMDM was added to bring the final concentration to 10% CCS, 1% pen strep per well. After 24 h, the cells were treated with vehicle, EtOH, or the ligand s ; indicated in the figures. Treatments were performed in triplicate within each experiment. After 30 h of treatment, the cells were lysed and the cleared extract was assayed for luciferase and -galactosidase -gal ; activities as described 31 ; . Luciferase activity was normalized using -gal activity and was expressed as relative light units as a ratio of activity detected in the EtOH controls. The effect of SHP on E2-stimulated reporter activity was normalized by the effect of SHP on basal luciferase activity for each concentration of SHP transfected. Statistical evaluations of data were performed using t test in Microsoft Corp. Excel and ANOVA in GraphPad Software, Inc. San Diego, CA ; Prism. The 50% inhibitory concentration IC50 ; values were calculated in GraphPad Software, Inc. Prism.

Since we tutor students on different topics in every module, each tutor has the opportunity to draw on and express her or his own strengths, interests, and particular knowledge in relation to each. At the same time the process enables us to extend our own knowledge and empowers, encourages, and re-energises us. For instance, we may be worried about the situation in our own country but then be re-inspired by hearing about another person's experience in our region.

DOES SALINE INFUSION IMPROVE THE SUCCESS RATE OF PREVIOUSLY INACTIVE EPIDURAL CATHETERS? AUTHORS: J. Ranasinghe, A. Lee, D. J. Birnbach, J. L. Steadman, T. Toyama; AFFILIATION: University of Miami, Miami, FL. INTRODUCTION: Several reports have suggested that failure to reactivate inactive labor epidural catheters for postpartum tubal ligation may occur in more than 20 % of cases and increase OR time and cost. Although the likelihood of successful reactivation appears to be inversely related to the period of disuse of the catheter following vaginal delivery the etiology of failure is uncertain, but may be related to loss of patency of the catheter. In our institution, epidurals are routinely placed preemptively in patients diagnosed with severe preeclampsia. Although many of these epidurals are left for prolonged periods prior to use, we still observe a very high success rate of activation of these catheters. Our hypothesis was that infusion of normal saline through inactive catheters would decrease the failure rate when reactivated. The results of a QA investigation are presented. METHODS: All patients diagnosed with severe preeclampsia with platelet counts greater than 75, 000 receive epidurals at this institution. Catheters placed are tested with lidocaine 1.5% with epinephrine and then infused with normal saline at a rate of 3-4 ml per hour. Catheters are activated at the onset of painful contractions with levobupivacaine and or used for cesarean section as necessary. RESULTS: For the period January 2002 to March 2003, a review of the QA database revealed 59 patients who had preemptive epidural placement with subsequent infusion of normal saline. Prior to activation, twenty three 39 % ; patients had catheters placed for a period of less than 4 hours, seventeen 29 % ; patients had catheters placed for between 4 and 8 hours, twelve 20 % ; patients had catheters in place for greater than 8 but less than 24 hours and seven 12% ; patients had catheters in place for greater than 24 hours. The longest period any of the catheters had been inactive was 67 hours. Successful activation was defined as any catheter which worked well to provide labor analgesia and or anesthesia for cesarean section. One patient underwent an emergency cesarean section under general anesthesia due to time constraints. That catheter was successfully used later for postoperative pain management. Another catheter was eventually discovered to be intrathecal and was replaced. All other catheters were successfully activated for labor analgesia or for cesarean section. DISCUSSION: Our experience reveals a 100% rate of successful activation of preemptively placed epidural catheters infused with normal saline. The majority of these catheters were first used more than 4 hours after placement, and in seven cases, after 24 hours. These data suggest that normal saline infusion improves the rate of successful reactivation of dormant epidural catheters, perhaps by ensuring the patency of the catheter. REFERENCES: 1.

13 Maximum peak currents were measured at each voltage step and normalized for the cell capacitance. The reversal potential EGlu ; was calculated after fitting the data with the GHK equation see Methods; Figure 3B ; . Using nearly identical Cl concentrations in the extracellular and intracellular solutions, glutamate-induced currents reversed in polarity at a membrane potential of + 2.6 mV n 4 ; , which was close to the calculated chloride equilibrium potential E Cl- 0.9 mV ; . At lower intracellular Cl concentrations, EGlu shifted to a more negative value 13.6 mV; n 3 ; , which was in good agreement with the expected shift in the calculated Nernst equilibrium potential for chloride ions ECl- 20 mV ; . These results clearly demonstrate that the glutamate-induced currents in locust DUM neurons are mainly carried by chloride ions.

The current study analyzed information on the 4, 247 men in the placebo group who had no erectile dysfunction or cardiovascular disease at the outset of the PCPT. Five years later, 57% of them had developed erectile problems. At seven years, the percentage had climbed to 65%. During the same follow-up period, men who developed ED were 25% more likely than men who did not have ED to experience some kind of cardiovascular event, such as angina chest pain ; , a heart attack, or a stroke. Bottom Line Advice: As a cardiovascular risk factor, ED ranks with current smoking or a family history of heart attacks. If someone develops ED, therefore, it is not merely a lifestyle issue. ED is an important warning of the risk.

Differential effects of dietary lipids and curcumin on kidney microsomal fatty acids and Na + , K ATPase activity in rat Joe B.; Prasad S.R.; Sambaiah K.; Krishnakanth T.P.; Lokesh B.R. Dept. of Food Chemistry, Central Food Technol. Research Inst., Mysore - 570013 India Nutr. Res. USA ; , 1992, 12 7 ; The effect of dietary lipids and spice principle curcumin on kidney microsomal lipids, Na + , K + - ATPase activity and serum lipid levels were studied. Rats were fed a diet containing either coconut oil, safflower oil or menhaden oil for 8 weeks. Safflower oil and menhaden oil feeding resulted in the accumulation of n-6 polyunsaturated fatty acids PUFA ; and n-3 PUFA respectively in the kidney microsomes. The specific activity of Na + , ATPase was higher by 26% in animals fed safflower oil when compared to animals fed coconut oil or menhaden oil. Supplementation of curcumin in the diets containing different lipids did not affect either the kidney microsomal fatty acid profiles or Na + , ATPase activity. However, dietary curcumin reduced the serum triglyceride level by 44% in safflower oil fed animals and serum cholesterol levels by 24% and 31% in animals fed safflower oil and menhaden oil respectively. These studies indicated that dietary lipids and curcumin differentially affect membrane fatty acid composition, Na + , K + - ATPase activity and serum lipids.
