Adenosine 5 -tetraphosphate (ATPP) was identified and quantified in extracts of rabbit platelets by elution of extracts containing authentic adenosine 5 -tetraphosphate and comparison of retention time with nucleotide standards using high-performance liquid chromatography technique. The amount of adenosine 5 -tetraphosphate was 0.62 nmoles/109 cells which was 62-fold lower than that of ATP but only 10-fold lower than that of ADP. During platelet aggregation induced by thrombin, adenosine 5...

Na+ activity, and twitch force are mediated by stimulation of the α1-adrenergic receptor, but not by stimulation of β-adrenergic receptor. The decrease in intracellular Na+ activity was not observed in quiescent muscles, depending on the rate of the action pontentials in beating muscles. The intracellular Na+ activity decrease was substantially inhibited by tetrodotoxin. However, the decrease in intracellular Na+ activity was not affected by an inhibition of the Na+-K+ pump. Therefore, the...

movement during this period were calculated, and the effects of vasopressin and prolactin on them were evaluated. Fellowing results were obtained: 1. The rate of reduction of [CR] in the AF was retarded by vasopressin or prolactin injection. 2. The rate of reduction of [Li+] in the AF was also retarded by vasopressin or prolactin injection. 3. The rate of reduction of [Li+] in the AF was less retarded by vasopressin than that of [CR]. 4. [Na+] changed to approach to the normal level, but this w...

among the weak acids tested, which was 4.9 X 10-3 in liposome, 5.0 X 10-3 in renal proximal tubule cell, 9.1 X 10-3 in BBMV and 3.8 X 10-3 in BLMV. There was a linear relationship between external concentration of nonionized formic acid and initial rate of flux of formic acid in liposome, and the slope coincided with the value of permeability coefficient of formic acid measured in pH 7.0. These results show that techniques of stopped-flow and epifluorescence microscopy with entrapped fluorophore...

or intravenously. ICV infusion (1.25 μL/min) of L-NAME (20 or 100 μg/kg) per minute for 60 min) increased the mean arterial pressure and heart rate. Plasma renin concentrations(PRC) were significantly lower in L-NAME-infused group than in the control. L-Arginine (60 μg/min, ICV) prevented the pressor response to ICV L-NAME. The pressor response was not affected by simultaneous intravenous infusion of saralasin, but was abolished by hexamethonium treatment. Intravenous infusion (40 μL/min, 10...

to determine the contribution of Na+/Ca2+ exchange to the modulation of contractility. Ouabain (10-5 M) or K+-free Tyrode solution caused an increase in tonic tension even in the presence of a Ca2+ channel blocker (10-6 M verapamil) and an α-receptor blocker (10-5 M phentolamine). After treatment with ouabain (10-5 M), contractions were augmented by reduction of external Na+ concentration. The longer the treatment with ouabain (10-5 M) was, the larger the amplitude of Na+-free contracture was....

Synthetic potassium channel openers (KCOs) are agents capable of opening K-channels in excitable cells. These agents are known to have their maximal potency in the smooth muscle tissue, especially in the vascular smooth muscle. Much attention has been focused on the type of K-channel that is responsible for mediating the effects of KCOs. As the KCO-induced changes are antagonized by glibenclamide, an KATP (ATP-sensitive K-channel) blocker in the pancreatic β-cell, KATP was suggested to be the...

cerebrospinal fluid (aCSF) with or without losartan (DuP 753), a specific Ang ll receptor subtype I (AT1) antagonist and saralasin, a combined AT1/AT2 antagonist was administered into the cerebral lateral ventricle. Hemorrhage was performed at a rate of 3 ml/kg/min far 5 min. Intracerebroventricular administration of losartan and saralasin had no effect on the basal blood pressure. However, in response to acute hemorrhage, central Ang ll antagonists produced a remarkably greater fall in blood...

of depressor neurons and the pathway by simultaneously observing changes in BP and the firing rate (FR) of cardiovascular neurons (CVNs) in the RVLM during the somatosympathetic reflex (SSR) elicited by peripheral nerve stimulation, since CVNs are known to contribute to the generation of the sympathetic nerve discharge. In 42 cats, anaesthetized with α-chloralose, single unit recording was performed, using carbon filament electrodes inserted into the RVLM, enabling estimation of the post R wave...
