The discharge patterns and peripheral nerve inputs to cardiovascular neurons were investigated in rostral ventrolateral medulla (RVLM) and raphe nucleus of cats. The data from the two were compared to determine their roles in cardiovascular regulation and the endogenous analgesic system. Animals were anesthetized with α-chloralose and single cell activities were recorded by carbon-filament microelectrode and their relationships with cardiovascular activity were analyzed. In RVLM area, a total...

The objective of the present study is to assess the contribution of bulk flow to the regulatory mechanism of amniotic fluid volume and its ionic concentration in the membranes surrounding the amniotic fluid. For quantitative assessment, we prepared 4 kinds of artificial amniotic fIuids (isotonic isovolumetric, hypotonic isovolumetric, isotonic hypervolumetric and hypotonic hypervolumetric ones) by replacing 70% of amniotic fluid of pregnant rabbits with water or normal Tyrode solutions....

The rostral ventrolateral medulla (RVLM) includes vasopressor neurons, which transmit activation signals to the intermediolateral nucleus (IML) of the spinal cord, where the preganglionic sympathetic nucleus is located, to raise arterial blood pressure (BP). However, controversy exists as to the possible depressor area in the RVLM and the pathway involved. The present study persued evidence far the location of depressor neurons and the pathway by simultaneously observing changes in BP and the...

We have reported that dopamine potentiates spontaneous contractions dose-dependently in guinea-pig antral circular muscle strips (Hwang et al, 1991). To clarify the underlying excitatory mechanism of dopamine on the gastric smooth muscle, the effects of dopamine on voltage-dependent Ca2+ currents and Ca2+ -dependent K+ currents were observed in enzymatically dispersed guinea-pig gastric myocytes using the whole-cell voltage-clamp technique. Experiments were also done using isometric tension...

Acute and chronic effects of ethanol (EOH) administration on the cardiovascular and hormonal responses to repeated hemorrhage were investigated in conscious normotensive Wistar rats and spontaneously hypertensive rats (SHR). The chronic EOH treated group received 5% EOH (vol/vol) ad libitum in the drinking water far the first week,10% for the last 2 weeks, and 20% for the last 5 weeks from the age of 6 weeks. The EOH free group received tap water. Chronic EOH and EOH free groups were randomly...

low, control or high sodium diet (2, 10 or 25 mmol Na/100 g diet) was fed for 6 weeks from the age of 6 weeks. On the morning of the experiment catheters were inserted under ether anesthesia in the femoral artery for pressure recording and blood sampling, and in the femoral vein for drug infusion. Ang II was infused at a rate of 250 ng/kg/min for 20 min. Nifedipine mixed with Ang II was infused at a rate of 16μg/kg/min for 20 min. Arterial blood samples were collected before and after infusion...

To study the regulation of amniotic fluid volume and electrolyte concentration by the Membranes surrounding the amniotic fluid, the rate of Li+ disappearance from amniotic sac of expired fetuses were examined while increasing the amniotic volume and osmolarity in rabbits. After intraamniotic injection of 1 ml isosmotic saline (about 20% of the amniotic fluid volume) containing 15 mM LiCl and 0.5 g/L Censored, the time courses of Li+ and Censored disappearance were determined. From there the Li+...

~ 10-3 M). The muscle preparation responded with contraction dose dependently to carbachol, of which dose response curve shifted to the right in the presence of either amitriptyline or atropine. However, amitriptyline produced a nonparallel shift, whereas atropine caused a parallel one. In calcium free medium, the contraction response to carbachol was markedly decreased, which was resumed by the addition of 2 (2.5mM), but not in the presence of either amitriptyline or nifedipine. KCI (60 mM)...

4. Ca2+-channel blockers(D-600 or Mn2+) and the blocker of intracellular Ca2+ release from sarcoplasmic reticulum(ryanodine) did not suppress the development of Na+-free contracture. And also, dinitrophenol had no effect on Na+-free contracture. 5. Dose-response relationship between extracellular Na+ concentrations and the magnitude of contractures showed a sigmoid pattern. The slope of straight line from Hill plot was 2.7. 6. In parallel with the increase of extracellular Ca2+ concentration, t...

to the level of the contraction at pH 7.4 by the elevation of extracellular. calcium [Ca2+]o. Adenosine-induced relaxation was more significant with 5% CO2 than 0% CO2 in the high K+-induced contraction and was more significant with low pHo than high pHo in the contraction induced by EFS. From the above results, it is suggested that H+ and CO2 inhibit Ca2+ influx as well as Ca2+ release from intracellular Ca2+ storage sites and enhance the relaxing effect of adenosine in the pig coronary artery.
