Another source of error for the calculation of poststenotic coronary resistance may be an underestimation of myocardial blood flow by varying amounts of collateral blood flow from the nonoccluded artery, since we measured only arterial inflow. Thus, the decrease in arterial inflow distal to a severe stenosis might be replaced by enhanced collateral flow during sympathetic stimulation, and poststenotic coronary vascular resistance may be constant. However, if we regard the difference between aortic and poststenotic coronary pressure as the driving pressure gradient for collateral blood flow, this gradient was rather reduced during sympathetic stimulation. In addition, the decrease in systolic segment shortening and the net lactate production of the circumflex-perfused myocardium during sympathetic stimulation indicate a real myocardial perfusion impairment. Thus, the reactions of calculated end-diastolic coronary resistance during cardiac sympathetic nerve stimulation are predominantly due to an interaction of metabolic dilatory mechanisms and sympathetic vasoconstriction in the poststenotic coronary vascular bed. ai- vs. a2-Receptors in the Mediation of Sympathetic Vasoconstriction Phentolamine decreased the resistance of the poststenotic vascular bed and prevented the increase in resistance during cardiac sympathetic nerve stimulation. These beneficial effects of phentolamine could be due to blockade of postjunctional a-receptors and the prevention of a-receptor-mediated vasoconstriction, as well as to blockade of prejunctional a-receptors and a metabolic vasodilation resulting from increased norepinephrine release Gorman and Sparks, 1982; Saeed et al., 1982 ; . To differentiate these mechanisms, we employed more specific drugs. Prazoosin is supposed to be a relatively specific antagonist of postjunctional ai-receptors Hoffman and Lefkowitz, 1980 ; , but failed to decrease the resistance of the poststenotic vascular bed and to prevent the increase in resistance during sympathetic stimulation. The same dosage of 1.2 mg kg prazosin intravenously has been employed in various vascular preparations without evidence of a partial agonism Holtz et al., 1982; Saeed et al., 1982 ; . Thus the increase in the resting resistance of the poststenotic vascular bed cannot be attributed to a partial a-agonism and is rather explained by the decrease in poststenotic perfusion pressure and thus by less distention of the dilated poststenotic vascular bed. The increase in poststenotic resistance during sympathetic stimulation was obviously resistant to a\ -antagonism. In contrast to prazosin, rauwolscine, which is a very potent a2-receptor antagonist McGrath, 1982 ; , was effective to the same degree as phentolamine, both in decreasing the resting resistance of the post. The primary implication of the doxazosin vs chlorthalidone results in ALLHAT is that doxazosin should not be used as initial or sole antihypertensive therapy in high risk hypertensive patients, such as those in enrolled in ALLHAT. However, this is a population broadly representative of hypertensive patients over 55 years of age. Should these findings be extrapolated to all alpha blockers or to other groups of hypertensive patients not represented in ALLHAT? I believe these results should be generalized to all alpha blockers. Although large clinical trials are not designed to determine mechanisms of action that might justify extrapolating the results to an entire drug class, there is not likely to be another large hypertension clinical trial comparing an alpha blocker with diuretic or other therapy proven to reduce events as initial therapy for hypertension. In addition, the alpha blocker prazosin was previously shown to not improve survival in CHF compared with placebo. 3 Since further morbidity mortality trials testing alpha blockers in any hypertensive or CHF population are not likely to be conducted in the future, it is reasonable to generalize the findings from these trials to all patients with hypertension or CHF; alpha blockers should not be used as initial or sole therapy based on the evidence currently available. Are alpha blockers safe to use as part of a multi-drug antihypertensive regimen? ALLHAT was simply not designed to address this question. Even on-treatment analyses to assess the impact on risk of concomitant therapy with other antihypertensive agents, which are being performed, cannot fully answer this question. It will be reassuring if concomitant therapy reduces the event rates, but it will not provide proof, since other drugs were added at varying times after.

The adjusted odds ratios derived from the regression parameter estimates show no significant result for Project C.A.R.E. pharmacies in the A group in decreasing the risk of severe GI outcomes. The statistical power for determining the effect of payment for cognitive services on death subsequent to a hospitalization for GI ulcer or hemorrhage is insufficient in the study population for any definitive measurement of risk. Hospitalizations with a primary diagnosis of GI bleed were not significantly decreased. Reports of GI bleed diagnoses during inpatient stays had non-significant decreases in risk in all models. Endoscopy procedures were not significantly reduced.

And elderly subjects as cardiac output is maintained by increasing heart rate in young whereas elderly subjects rely on an increase in stroke volume to compensate hypotension [105]. Intravenous administration of diltiazem causes greater prolongation of PR interval in young than in elderly subjects [106]. Elderly subjects may show less sensitivity to the effects of calcium channel blockers on cardiac conduction [103]. -1 Adrenoceptor Blockers Prqzosin is an antihypertensive drug which acts through inhibition of -1 adrenoceptors. When the drug was given in a dose of 1mg orally to young and elderly subjects, no change in its pharmacokinetics was reported between the two age groups. In spite of this, the haemodynamic effects of the drug were greater in the elderly. The fall in systolic blood pressure and mean blood pressure was significantly greater in the elderly group at multiple time points after drug administration while the change in diastolic blood pressure was equivalent in the two age groups. Despite a greater decrease in mean blood pressure in the elderly, the compensatory increase in heart rate was similar in the two age groups suggesting a difference in the baroreceptor reflex in the two age groups Figs. 1 & 2 ; [107]. -Adrenoceptor Agonists and Antagonists The physiological changes associated with ageing may affect the functional state of -adrenoceptors which become less responsive to their agonists such as isoproterenol and antagonists such as propranolol. When isoproterenol was infused in young normotensive subjects, older normotensive subjects, young hypertensive subjects, and older hypertensive subjects, similar increases in heart rate isoproterenolinduced ; in all four groups has been recorded. On the other hand, older hypertensive subjects showed some blunting of left ventricular responses to isoproterenol compared with older normotensive subjects Fig. 3 ; [108]. A previous study was carried out to determine the dose of isoproterenol required to increase heart rate HR ; by 25 beats min before and during a continuous infusion of propranolol. Advanced age group showed significant decrease in the sensitivity to the agonist effects of isoproterenol and to the beta-blocking. In our experience such patients are diagnosed more rapidly than the patients in our article. In the latter, the emphasis was on disorders that are associated with normal or low normal blood pressure. It is a common observation in these patients that often a specific diagnosis of the hypokalaemia is not established for several years. Nephrology Univ. Klinikum C. G.

Rhian M Touyz, Glaucia Callera, Dierk Endemann, Carmine Savoia, Ying He, Guoying Yao, Ernesto L Schiffrin, Clinical Research Institute of Montreal, Montreal, PQ, Canada We previously demonstrated that Ang II mediates many of its vascular pleiotropic actions via c-Src-dependent signaling pathways. In addition, we showed that development of hypertension is attenuated in c-Src mice. In the present study we questioned whether inhibition of c-Src, with CGP77675 CGP ; , a selective Src inhibitor, would decrease systolic blood pressure SBP ; in hypertensive mice and whether vascular functional and structural changes associated with hypertension could be ameliorated by Src inhibition. Male c-Src and c-Src - mice n 5 8 group ; were infused with Ang II 400 ng kg min, Alzet minipumps ; for 2 weeks. CGP 25 mg kg day, subcutaneously ; was administered to c-Src mice for the last 5 days of Ang II infusion. Control mice were infused with vehicle. To establish whether effects are Ang II-specific, c-Src - mice were also infused with L-norepinephrine 5.6 mg kg.day ; . SBP increased significantly in Ang II-infused c-Src mice 159 9 mmHg ; p 0.01 vs vehicle ; . CGP decreased SBP in Ang II-treated c-Src mice 122 9.8 mmHg ; to a similar level as Ang II-infused c-Src - mice 138 14 mmHg ; . This was associated with improved endothelial function 70% vs 35% Ach-induced vasodilation, Ang II CGP vs Ang II ; , decreased contractility of small mesenteric arteries 15% vs 28%, Ang II-induced contraction ; and a trend to regression of vascular remodeling. Norepinephrine significantly increased SBP in c-Src mice 165 9 mmHg ; . These data demonstrate that selective c-Src inhibition by CGP decreases SBP and prevents vascular damage in Ang II-infused mice. Blood pressure elevating actions of Ang II, but not of norepinephrine, were blunted in c-Src-deficient mice, suggesting that Src effects are not generalized phenomena. Our findings indicate that c-Src may be a putative target for intervention in the treatment of hypertension. MM ; . In addition, rapid stimulation further enhanced automaticity after exposure to norepinephrine, as previously reported.'4 Therefore, we could not evaluate the ability of norepinephrine to induce delayed afterdepolarizations and triggered activity at this Ca + + concentration. However, at a high Ca + + concentration 8.1 mM ; this enhanced automaticity was not observed in three of four preparations, and 10 7M to -6M norepinephrine produced delayed afterdepolarizations and nondriven triggered action potentials in each of these three preparations figure 7 ; . When 5 x 10-7M prazosin was added to the superfusate of the three preparations that could be studied, induction of afterpotentials was not affected, but inducibility was then and triamterene!

The Table confirms the lack of any effect of a 8-methylene-ATP. The four a-adrenoceptor antagonists used in experiments without [3H]-noradrenaline were also examined. Phentolamine, phenoxybenzamine and yohimbine all caused a marked increase in the electrically evoked overflow of tritium with only minor acceleration of basal efflux. In contrast, the only effect of prazosin was a pronounced increase in basal tritium outflow and methyldopa.

Duced by a-adrenergic stimulation. After a 60 min equilibration period and 30 min of superfusion with 5 x 10-7M propranolol, delayed afterdepolarizations and triggered activity were not recorded at drive cycle lengths of 500 through 200 msec in any of 10 preparations. Even after the extracellular calcium concentration was elevated from 2.7 to 8.1 mM, no clearly discernible delayed afterdepolarizations were recorded. However, after 10 to 15 min of exposure to 10-5M phenylephrine following 30 min of superfusion with high-Cal + solution, delayed afterdepolarizations were induced at a drive cycle length of 250 or 200 msec in eight of the 10 preparations, and nondriven triggered action potentials were recorded in three of the eight preparations that displayed delayed afterdepolarizations. The delayed afterdepolarizations and triggered activity induced by phenylephrine in the presence of propranolol were almost completely suppressed by the addition of either 5 x 10-7M prazosin n 5 ; or -6M phentolamine n 3 ; figure 1 ; .

They can enhance the excretion of sodium and water, thereby decreasing circulating blood volume and thus ventricular preload. Vasodilators can act to dilate either the arteriolar or venous side of the circulation or both. Agents that relax the peripheral arterioles will diminish the increased resistance against which the ventricle must empty thereby resulting in an increase in cardiac output. Additionally, the improvement in pump performance produced by arteriolar vasodilators is often accompanied by a reduction in myocardial oxygen consumption, since both systolic pressure and heart size are reduced. Alternatively, agents that dilate the postcapillary venous capacitance beds cause a redistribution of intravascular blood volume from the central to the peripheral reservoir, venous pooling ; and decrease venous return. In patients with heart failure, reducing venous return can lower cardiac filling pressures and relieve the clinical signs of increased pulmonary capillary pressure such as dyspnea. An increasing number of vasodilators are now available which, either alone or in combination, are capable of producing substantial decreases in ventricular filling pressures and systemic vascular resistance. These agents include: direct acting vasodilators such as minoxidil, hydralazine, and the nitrates; alpha-adrenergic receptor blockers such as phentolamine, prazosin and trimazosin; calcium channel antagonists such as nifedipine, verapamil and diltiazem and angiotensin converting enzyme inhibitors such as captopril, enalapril and lisinopril. Several other compounds, which combine inotropic and vasodilator activity are also available. These include the betal receptor agonists, such as prenalterol and pirbuterol, and the beta2 receptor agonists, such as salbutamol. In addition there is a group of non-catecholamine, non-glycoside inotropic agents with vasodilator actions including amrinone, milrinone, enoximone and fenoximone. Many of these agents are still under investigation. Although these compounds have several different modes of action, it has been possible to show short-term hemodynamic improvement with each of them, as well as some improvement in clinical signs and symptoms. However, only a few have demonstrated long-term benefits. Twenty years ago phentolamine became the first vasodilator specifically utilized to reduce preload and afterload in patients with severe heart failure. Although the drug produced marked decreases in ventricular filling pressures and increased cardiac output, its tendency to produce tachycardia led to its rapid replacement by intravenous sodium nitroprasside as the drug of choice for acute intravenous vasodilator therapy. Oral nitrates were used for the long-term treatment of patients with CHF. Isosorbide dinitrate, a widely used, orally-active, nitrate compound, decreases ventricular filling pressures in many.

Safety than live-attenuated vaccines as they are unable to revert to more virulent strains in preparation or in vivo. Such vaccines can, however, be less immunogenic and often require adjuvants to boost reactivity. They are, therefore, more likely than live vaccines to cause sideeffects such as injection-site reactions. KILLED WHOLE VIRUS VACCINES The earliest inactivated HSV vaccines employed fractions of HSV proteins from infected cell populations with or without purification. Skinner et al.79 tested formalininactivated HSV-1-infected human embryonic lung cell lysates in HSV serodiscordant couples to prevent genital HSV disease. Heat inactivated whole virus preparations in an HSV-1 background Lupidon H ; and an HSV-2 background Lupidon C ; were evaluated as therapeutic vaccines in an open-label trial in Italy.10 The patients received 12 weekly injections until a clinical response was observed, before progressing to maintenance injections every 36 months. These vaccines remain commercially available in Europe. For all these preparations, problems with study design made reports of a good clinical response difficult to interpret. The efficacy of these preparations has not been confirmed in doubleblind, randomized, controlled, clinical trials. Hypertension and resulted in a possible reflex tachycardia see Fig. 3 ; . Alternatively, dose-dependent effects of baclofen have been described in in vitro studies of NTS 5 ; . Low doses of baclofen produced presynaptic inhibitory effects, whereas higher doses produced a mixture of pre- and postsynaptic inhibition. In this model, we might speculate that, with a higher dose of baclofen, we would observe enhanced hypertension and significant tachycardia. Treatment in those animals with prazosin and VP receptor antagonist completely reversed hypertension and resulted in no change in HR. Considering that we are using microinjections, we may speculate that different doses of baclofen could be altering the activity of different subpopulations of neurons in the NTS. These data indicate the involvement of the two systems studied after the inhibition of the NTS by bilateral microinjections of baclofen in conscious rats: 1 ; the SNS and 2 ; the release of VP. According to our results, the main system responsible for the hypertension that followed NTS inhibition is the SNS once systemic administration of prazosin was able to completely reverse the hypertension. In conclusion, our results show that the hypertension induced by baclofen microinjected into the NTS of conscious rats was produced by increases in sympathetic tonus and may involve the release of VP. These data suggest that NTS neurons exert a tonic inhibitory influence on the SNS and possible mechanisms related to VP release.

Reference. P-glycoprotein is a 130-180-kDa integral membrane protein that is overproduced in multidrug-resistant cells. The protein appears to act as an energydependent drug efflux pump that has broad specificity for structurally diverse hydrophobic antitumor drugs. Many agents, such as the calcium channel blocker verapamil, reverse multidrug resistance and also interact with P-glycoprotein. The goal of this work was to determine if a common binding site participates in the transport of antitumor drugs and or the reversal of drug resistance. This was done by comparing the peptide maps of P-glycoprotein encoded by mdrl b ; after it was labeled with a photoactive calcium channel blocker, [3H]azidopine, and a newly identified photoaffinity analog for P-glycoprotein, 2-[4- 4-azido-3[12SI]iodobenzoyl ; piperazin-1-yl]-4-amino-6, 7-dimethoxyquinazoline [12SI]iodoaryl azidoprazosin ; . [1251] Iodoaryl azidoprazosin, which classically has been used to identify the al-adrenergic receptor, bound to Pglycoprotein and was preferentially competed by vinblastine actinomycin D doxorubicin colchicine. Peptide maps derived from P-glycoprotein labeled with [3H]azidopine or [12SI]iodoaryl azidoprazosin were identical. After maximal digestion under conditions for Cleveland mapping, a single major 6-kDa fragment was obtained after digestion with VS protease, whereas two major fragments, 6.5 and 5.5 kDa, were detected after digestion with chymotrypsin. The 6.0-kDa VS fragment and the 6.5-kDa chymotrypsin fragment were both found when P-glycoprotein encoded by mdrla and mdrl b was compared. Despite its specific interaction with P-glycoprotein, neither iodoaryl azidoprazosin nor prazosin markedly reversed resistance compared with verapamil or azidopine. Further, multidrug-resistant cells were 900-fold resistant to vinblastine but only B-fold resistant to prazosin. These data demonstrate that structurally diverse reversal and or antitumor agents are likely to have differential affinity for a small common domain of Pglycoprotein and buy lanoxin.

However, the values for both groups are relatively high compared with concentrations in protein-stressed cows of similar breeding Miner and Petersen, 1989; Lodman et al., 1990 ; , which indicates that dietary protein satisfied requirements for milk production and tissue growth. The higher BUN concentration of the UD-fed cows may be indicative of excess protein fed, resulting in deamination of the amino acids and the carbon skeleton used for oxidation metabolism. Glucose concentration was not affected by either prepartum nutrition level or postpartum protein source Table 5 ; . Glucose is usually found in limited concentrations in the lactating ruminant; therefore, large differences in nutrient content of our supplements or large changes in animal metabolism would be required to cause accumulation of serum glucose. Serum albumin was affected by prepartum nutrition level P .05 ; but not by postpartum protein source. Serum cEatinine concentrations were not affected by prepartum nutrition level or postpartum protein source, suggesting that skeletal muscle was not severely catabo. In a three-week clinical trial, the efficacy of alfuzosin was compared with that of prazosin in the symptomatic treatment of BPH. A total of 103 patients were assigned to take alfuzosin 2.5 mg three times daily or prazosin 2 mg twice daily, at a gradual dose increase within the first week. After three weeks, voiding symptoms, according to Boyarsky scores and urination diaries, improved in the two groups, revealing similar increases in peak and mean urinary flow rates. Peak flow rates for alfuzosin were 2.6 0.6 ml second, and those for prazosin were 2.9 0.7 ml second. The alfuzosin group demonstrated a greater increase in the mean flow rate and voided volume 30% and 22.2%, respectively ; , compared with the prazosin group 20.6% and 6.5.
