Estrous cyclicity was monitored by means of vaginal lavage, and only those rats showing 4-day cycles were used. Rats were OVX on the morning of diestrous day 1 D1 ; at about 1000 h. After ovariectomy, rats were immediately inserted estradiol E2 ; -containing Silastic capsule Cat.

All the rats received 2 mg of progesterone Sigma ; s.c., at 0930 h the next morning the expected diestrous day 2, D2 ; as previously described Pi and Lin, 1991 ; . At 1200 h, the rats received a saline vehicle group A 0.84 mg or 4.2 mg kg of prazosin HCl Pfizer ; , an 1-adrenergic antagonist group B and C 0.80 mg or 4.0 mg kg of youimbine HCl Sigma ; , an 2-adrenergic antagonist group D and E or 0.52 mg or 2.6 mg kg of propranolol HCl Sigma ; , a -adrenergic antagonist group F and G ; s.c., respectively.

Determining whether the detrimental effects of drugs anticipated from laboratory studies also occur in humans is difficult but important, because many of these medications are commonly given to patients recovering from stroke. In a retrospective cohort study, the level of motor recovery of patients who had a stroke and who received, either alone or in combination, the antihypertensives clonidine or prazosin, dopamine receptor antagonists, benzodiazepines, or phenytoin drugs that were anticipated to impair recovery based on the results of laboratory studies ; was compared with the level of recovery of a similar group of patients who were not given any of these medications. Patients who received the drugs had poorer levels of recovery than did the control patients. Multivariate regression analysis indicated a significant effect P .025 ; of "drug group" even after correcting for the contributions of other variables, including the initial severity of the deficit. A similar effect was found in a separate cohort of patients with anterior circulation ischemic stroke, who were enrolled as control patients in a short-term interventional stroke trial. Almost 40% received 1 or a combination of drugs hypothesized to impair recovery during the first 30 days after stroke. As with the previous study, stepwise multivariate analyses indicated a negative effect on outcome in the drug group, independent of the degree of the initial motor impairment, comorbidconditions, because both studies involved retrospective analyses, whether the reason for the administration of a given drug or the drug itself influenced recovery cannot be determined. Furthermore, the effects of specific "detrimental" drugs, dosage, and timing could not be analyzed. Physicians caring for patients recovering from stroke should become aware of the potential negative effect of drugs commonly prescribed to treat other conditions. Whenever possible, these drugs should be avoided. As the basic neurobiological factors underlying recovery become better understood, drugs targeted at enhancing the recovery process may become part of the standard treatment of patients who have had a stroke.

Sad to say but prazosin is a protein prazosin is a good idea for chronic pain and vermox.
Sumption that the total blood volume of the rat is 7 ml 100 g and that this volume is not altered during the study. If it were to increase, then the calculation of the percentage of activity remaining intravascular would be in error by a percentage equal to the percentage decrease in hematocrit. Although blood volume was not measured and hematocrit was measured only after treatment, comparison of labeling efficiency and hematocrits in the several groups provides some insight into the contribution of blood volume to this effect. Only the group of animals treated with prazosin had a mean hematocrit that was significantly lower than control. This difference was 13%, and thus can account for a substantial portion of the observed diminution in intravascular activity. In contrast, the digoxin-treated rats had a significant reduction of intravascular activity without any difference in the hematocrit. Thus, the observed loss of radioactivity may be partially due to an increase in blood volume in duced by prazosin, although this cannot explain the digoxin effect. Clearly, the transit of tracer from one compartment to another is a complex process whose dynamics cannot be characterized by observations at only two points in time. The data presented here demonstrate an inhibition, by two distinctly different Pharmaceuticals, of RBC labeling with Tc-99m. The findings are highly suggestive that at least some of this unbound tracer is in the extravascular space. Relatively little is known about the mechanism of binding of technetium to red blood cells. Whether the cells are labeled in vivo, in vitro, or by a hybrid method, stannous ion is required for efficient labeling in both animals and in humans. Callahan et al. 3 ; showed that labeling kinetics are critically dependent upon temper ature, stannous ion concentration, and hematocrit. The binding of the tracer is to the beta chain of hemoglobin 14 ; but the mechanism of transport across the red-cell membrane, as well as the means by which stannous ion mediates binding, are obscure. Interference with radionuclide distribution by com monly used Pharmaceuticals and other agents is well described 5 ; . A significant number of patients being studied with radionuclide ventriculograms are receiving medication, which may include antihypertensive agents or digoxin. Tc-99m-labeled RBCs are widely used as a blood-pool label. Our data suggest a potential interfer ence by patient medication with the performance of blood-pool studies. It is necessary to explore the effect of other Pharmaceuticals on Tc-99m binding to RBCs in order to identify potential labeling problems in the clinical setting.

It is of critical importance that a versatile in vivo model be developed to assess the therapeutic efficacy of the drugs used in the treatment of premature ejaculation. Hsieh et al 1998 ; proposed a rat model involving electrical stimulation of the lesser splanchnic nerve to induce changes in the intraluminal pressure of seminal vesicles. They measured the inhibition of electrical stimulation induced seminal vesicle pressure increases induced by several agents ie, prazosin, 5-HT, clomipramine, fluoxetine, imipramine, or indatraline ; and observed concentration-dependent effects for prazosin and all serotonergic agents, except imipramine and indatraline. Of these inhibitory agents, highest efficacy was observed for fluoxetine followed by prazosin, 5-HT, and clomipramine. On the other hand, Kim et al 2000 ; used a somewhat different model and produced results that contest those of the Hsieh study. They investigated the effects of serotonergic drugs clomipramine, sertraline, paroxetine, or fluoxetine ; on the vasal pressure increase induced by electrical stimulation of the hypogastric nerve. All serotonergic drugs were found to cause a concentration-dependent inhibition of intraluminal pressure elevation in the vas deferens, and clomipramine showed the strongest inhibitory effect followed by sertraline, paroxetine, and fluoxetine. Aside from the differences between these 2 models in terms of target organ seminal vesicle vs vas deferens ; and stimulated nerve lesser splanchnic nerve vs hypogastric nerve ; , there were qualitative differences in the and mefenamic.

Using E. coli strains deficient in enterobactin synthesis and uptake entF and tonB mutations ; , we [19] and others [22] have shown that for Gram-negative bacteria, a functional siderophore system is an integral element in the mechanism by which bacteria assimilate the Tf Lf-complexed iron made available by the interaction of the catecholamine with the host iron binding protein. We therefore hypothesized that a possible mechanism by which the -adrenergic antagonists were blocking catecholamine-induced bacterial growth might be through interference with the catecholamine-mediated uptake of Fe from Tf. The ability of -adrenergic antagonists to specifically block catecholamine-mediated uptake of Fe from Tf was examined with the use of 55Fe-labelled Tf as described in Materials and Methods. As shown in Table 5, bacterial 55Fe uptake assays were performed in the presence of NE and Epi and were challenged with concentrations of phentolamine, phenoxybenzamine or prazosin which had been shown in Table 2 to inhibit the ability of NE and Epi to induce growth by at least 2 log orders. The results of such 55Fe uptake assays clearly demonstrated that the -adrenergic antagonists caused no significant reduction in the ability of the catecholamines to mediate bacterial 55Fe acquisition from 55FeTf, and that only the addition of Fe affected the amount of 55Fe that was internalized by each of the bacterial strains Table 5 ; due to.
The effective doses of each antagonist required to produce the following effects were calculated: maximum 50% inhibition of IUP pressor effect 1 ; , maximum 50% inhibition of MAP pressor effect and 2 ; , 10 mm decrease in baseline MAP 3 ; . Uroselectivity ratios are summarized in the last two columns. Using the first two indices, the IUP selectivity of fiduxosin 7.5-fold ; was superior to that of tamsulosin 1.5-fold ; or terazosin ratio 0.4- or 2.5-fold MAP-selective ; . IUP selectivity as defined by IUP versus hypotensive effects yields the same rank order: fiduxosin 12.5-fold ; tamsulosin 7.5-fold ; terazosin 0.7-fold ; . The actual uroselectivity of fiduxosin may be underestimated as the absence of hypotension after fiduxosin precludes an absolute estimate. Selectivity Ratio IUP ED50 1 ; MAP ED50 2 ; Hypotensive ED10 mm Hg 3 ; subtype agonist such as PE would not be a confounding factor in the case where a single subtype mediates the functional responses of the agonist. For most 1-adrenoceptor antagonists, including fiduxosin, there is a strong positive correlation between affinity for the LUT predominant 1A ; subtype and functional antagonist potency on LUT tissue in vitro and in vivo Hancock, 1996; Hancock et al., 2002 ; . However, some compounds have been described that have much weaker functional potency in prostatic tissue in vitro than would be predicted by their affinities for the recombinant 1a-subtype such as SNAP 5089, REC 15 2627 Leonardi et al., 1997 ; , and RS 17053 Ford et al., 1996 ; . This has lead to the hypothesis that contraction of prostatic and urethral ; tissue is mediated at least in part by an atypical 1-adrenoceptor subtype, possibly the putative 1L-subtype low affinity for prazisin ; initially proposed by Flavahan and Vanhoutte 1986 ; and extended by Murumatsu et al. 1990, 1995 ; to explain the differences in the affinity constants for prazsin in different vascular tissue assays in vitro. Current data support the notion that the 1L-"subtype" may not be a distinct molecular entity but rather as a different "affinity state" of the 1A-adrenoceptor gene product. The fiduxosin in vitro data Hancock et al., 2002 ; suggests that, unlike the outlier compounds described above and like most other 1-adrenoceptor antagonists, the affinity of fiduxosin for the 1A-adrenoceptor is independent of its affinity state. In a previous article on the effects of tamsulosin and terazosin in this model Brune et al., 1996 ; , the results were reported using PE at 16 i.v., whereas 32 g kg i.v. is used herein. We routinely administered three PE doses in the protocol not knowing a priori where these three doses might lie on the dose-response curve in a particular dog. For example, if PE 32 g i.v. was a supramaximal IUP dose on a given day, an antagonist might cause less IUP blockade and therefore look less selective. Comparing the effects of multiple agonist doses helps evaluate compounds as to their ability to shift a dose response to the right instead of inhibition of effects at only a single dose. In hindsight, antagonist blockade of all PE doses was similar in different dogs on different days, indicating that these doses all lie on the "steep" portion of the dose-response curve and that compound potency and selectivity was not affected by such issues. In this study, we demonstrated the utility of a conscious dog model to demonstrate selective functional 1-adrenoceptor antagonism in the lower urinary tract urethra and prostate ; compared with the vascular system. This model appears relevant because 1 ; the 1A-adrenoceptor subtype is predominant in the LUT of both dog and human, 2 ; the pharmacology of dog lower urinary tract 1-adrenoceptors is similar to that of human Lepor et al., 1992, 1994 ; , and 3 ; androgen and metaproterenol and prazosin.

Acute pharmacological blockade of 1 adrenoreceptors ARs ; attenuates the locomotor response to amphetamine LRA ; . We took a genetic approach to study how norepinephrine NE ; signaling modulates psychostimulant responses by testing LRA in dopamine -hydroxylase knockout Dbh ; mice that lack NE. Surprisingly, Dbh animals were hypersensitive to the behavioral effects of amphetamine. Amphetamine 2 mg kg ; elicited greater locomotor activity in Dbh mice compared to controls, whereas 5 mg kg caused stereotypy in Dbh mice, which is only observed in control mice at higher doses. Prazosin, an 1AR antagonist, attenuated LRA in Dbh mice but had no effect in Dbh mice. Changes in the sensitivity of dopamine DA ; -signaling pathways may contribute to the altered amphetamine responses of Dbh mice because they were relatively insensitive to a D1 agonist and hypersensitive to a D2 agonist. Daily amphetamine administration resulted in behavioral sensitization in both Dbh and Dbh mice, demonstrating that NE is not required for the development or expression of behavioral sensitization. Daily prazosin administration blunted but did not completely block locomotor sensitization in Dbh mice, suggesting that 1AR signaling contributes to, but is not required for sensitization in Dbh control animals. We conclude that in contrast to acute 1AR blockade, chronic NE deficiency induces changes similar to sensitization, perhaps by altering DA-signaling pathways.

After the blockade of -ARs with propranolol, epinephrine increased [Ca2 + ] dose-dependently in 2 + both the presence and absence of extracellular Ca . The rank order of a antagonists in inhibiting [Ca2 + ] i response to epinephrine was yohimbine WB4101 prazosin in both the pres2 + ence and absence of extracellular Ca , suggesting that epi2 + nephrine acts on et2A-ARs to increase Ca influx as well as Ca2 + release from intracellular stores. Thapsigargin, the blocker of the 2 + Ca pump in the sarcoplasmic reticulum, abolished the release but did not affect the influx. Pertussis toxin PTX ; inhibited the influx but failed to change the release. Nimodipine, an L-type 2 + Ca channel blocker, nearly abolished the influx. The peak increase in [Ca2 + ]i caused by epinephrine was reached within 20 sec of administration. Intracellular cAMP concentrations were also decreased at 20 sec post-epinephrine. Epinephrine en2 + hanced the L-type Ca channel current, whereas forskolin suppressed it. Maximization of intracellular cAMP content by applying 8-bromo-cAMP 100 uM ; blocked the effect of epinephrine on the current. U-73122, a phospholipase C inhibitor, reduced the Ca2 + release by epinephrine and oxytocin. Our results 2 + suggested that 1 ; activation of Qo 2-ARs induces Ca influx 2 + 2 through opening L-type Ca channels as well as inducing Ca release from intracellular stores, and 2 ; a PTX-sensitive G protein couples negatively to adenylyl cyclase, leading to a decrease in cAMP formation which may be involved in the activation of 2 + channels. In addition, our results are consistent with the coupling of a2-ARs to a PTX-insensitive G protein Gq ; to release 2 Ca + from intracellular stores. INTRODUCTION Alpha 2-adrenergic receptors 2 -ARs ; mediate a variety of cell functions including inhibitory effects, such as suppression of neurotransmitter and hormone release, and stimulatory effects, such as aggregation of platelets and contraction of smooth muscles, including myometrium [1, 2]. The oa -AR-mediated inhibitory effects are attributable to 2 the activation of pertussis toxin PTX ; -sensitive G proteins Gi Go ; , which then couple to various effectors including adenylyl cyclase and ion channels [3, 4]. However, the mechanisms by which a 2-ARs mediate contraction of smooth muscles, including myometrium, remain poorly understood.

The a 2-AR-mediated rise in intracellular free calcium concentration [Ca2 + ]i ; and subsequent smooth muscle contractions depend on the Ca 2 + influx via the voltage-dependent Ca 2 + channel VDCC ; through the activation of a PTX-sensitive G protein [7]. Yet the coupling mechanism that explains how the PTX-sensitive G protein activates the VDCC has not been established. Alpha-ARs in porcine myometrial cells are predominantly a2-ARs [2, 8]. Activation of a 2-ARs in these cells causes contractions in Ca 2 -free medium [1, 9]. These findings suggest that ot2-ARs, in addition to acting on the Ca 2 + influx, may also induce Ca 2 + release from intracellular stores of the myometrial cells. The main goal of this study was to investigate the cellular mechanisms by which a 2-ARs regulate the Ca 2 + signal in porcine myometrial cells. We used epinephrine, an endogenous adrenergic agonist, in the presence of a -AR blockade by propranolol to activate a-ARs. Another reason for using epinephrine was that in our preliminary experiments, only catecholamines, but not synthetic ca-agonists, consistently increased [Ca 2 + ]i porcine myometrial cells. MATERIALS AND METHODS Preparation of Myometrial Cells Porcine uteri of the luteal phase were obtained from a local packing plant. The luteal phase was determined through visual inspection of the ovary by the presence of corpora lutea and the absence of embryos. Single myometrial cells were isolated as previously described [10]. Ca2 + Measurements Using Fluorescence Photometry [Ca2 + ]i was measured as previously described [10]. Myometrial cells were gently shaken in Krebs-Ringer buffer KRB ; solution containing 4 LM Fura-2 acetoxymethylester Molecular Probes, Eugene, OR ; at 37C for 45 min. The Fura-2-loaded cells were centrifuged 50 x g ; and diluted to 2 x with KRB. Fura-2 fluorescence was monitored in a spectrofluorometer with excitation wavelengths of 340 nm and 380 nm and an emission wavelength of 510 nm. For experiments conducted in the Ca 2 + -free condition, the cell suspension was centrifuged 300 x g, 1 min ; and the medium was replaced with the Ca 2 + -free KRB supplemented with 0.1 mM EGTA immediately before [Ca2 + ]i measurements. Ca2 + Current Recordings The whole-cell patch-clamp technique was used to record Ca2 + current as described previously [10]. Patch pipettes 3-5 Mfl ; were prepared from disposable glass pipettes VWR Scientific, West Chester, PA ; by a two-stage pull and a fire polishing. The liquid junction potentials were nullified before the formation of gigaseals with an offset circuit. Data were collected and analyzed using an IBM-PC.
