The role of endogenous brain angiotensin ll (Ang ll) in mediating the cardiovascular and vasopressin responses to hemorrhage was assessed in conscious spontaneously hypertensive rats (SHR), and normotensive Wistar-Kyoto (WKY) rats. Artificial 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...

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...

The effects of changes in extracellular Na+ and Ca+ concentration on the membrane potential and contractility were studied in the antral circular muscle of guinea pig stomach in order to elucidate the existence and the nature of Na+/Ca2+ exchange mechanism. All experiments were performed in tris buffered Tyrode solution which was aerated with 100% O2 and kept at 35℃. The treatment of 10-5 ouabain was performed to induce intracellular Na+ loading prior to the start of experiment. The results...

During the past few years it has been proposed that lithium clearance can be used as a reliable measure for the outflow of tubular fluid from the proximal tubule. This study was aimed to characterize the inflow dependent reabsorption of Na in renal tubule beyond the proximal tubule. For this purpose, lithium clearance was used as a measure for the inflow from the proximal tubule and the changes in reabsorption fraction of Na and water were determined in rabbits. Rabbits were pretreated with...

This study was carried out to determine effect of acute renal ischemia on transport function of organic cation, tetraethylammonium (TEA), in rabbit kidney proximal tubule. Clamping of the renal artery for 30 and 60 min produced a polyuria which was accompanied by an increase in Na+ excretion. The capacity of kidney cortical slices to accumulate TEA was increased after 30 and 60 min of ischemia. When blood flow was restored for 30 min after 30 and 60 min of ischemia, the augmented TEA uptake was...

a pH gradient was accelerated by pulse injections of Na+ in a saturable manner and Li+ could replace Na+. The kinetic parameter of Na+ in placental Na+/H+ exchange was similar to that of renal Na+/H+ exchange. Amiloride was a inhibitor of directly coupled Na+/H+ exchange and its IC50 in placental MVV was about 14-fold higher than that in renal brush border membrane. These results indicate that Na+/H+ exchanger exists in human placental MVV and that its kinetic characteristics is similar to that...

Single smooth muscle cells of the rabbit pulmonary artery were isolated by treatment with collagenase and elastase. Using the patch clamp technique, potassium channel activity was recorded from the inside-out membrane patch. The channel had a sin히e channel conductance of about 360 pS in symmetrical concentration of K on both sides of the patch, 150 mM, and had a linear current-voltage relationship. During the application of 10 mM tetraethylammonium (TEA) to the intracellular membrane surface,...

고양이 회장 종주근에서 세포막 소포를 분리하여 Na+의 농도 경사에 의존하여 일어나는 Ca2+ 이동의 특성에 대하여 연구하였다. 막소포 내부에서 외부로 향하는 Na+의 농도 경사 존재시 Ca2+의 축적이 현저히 증가하여 Na+ 의존성 Ca2+ 축적을 보였으며, 이는 외부용액에 Na+ ionophore인 monensin을 처리시 소실되었다. 한편 이러한 Ca2+ 축적의 증가 작용은 Na+에 특이적이었으며 K+, Li+, Rb+, Cs+ 및 choline이온은 Na+의 작용을 대치하지 못하였다. Ba2+, Sr2+, Mn2+ 및 Cd2+ 등의 2가 양이온들은 0.5 mM의 농도에서 Na+ 의존성 Ca2+...

심근정지용액의 조성이 심근정지 및 심근정지 후 회복기의 에너지원에 미치는 영향을 조사하기 위해 guinea pig 심실 균질액에서 adenosine triphosphate (ATP), creatine phosphate (CP) 및 lactic acid (LA)의 변화를 관찰하여 다음과 같은 결과를 얻었다. 1) ATP 및 CP 양은 심근정지동안은 감소하고 회복기에는 다시 증가하였으며, 심근정지 후 정상용액으로 30분간 회복시켰을 때에는 ATP 양의 회복이 CP에 비해 느린것을 알 수 있었다. 2) LA 양은 심근정지동안은 증가하고 회복기에는 다시 감소하였다. 3) 심근정지 후 회복시간을...

가토 신장 피질에서 Percoll density gradient방법으로 분리한 basolateral membrane vesicle (BLMV)에서 rapid filtration technique을 이용하여 succinate의 이동 특성을 관찰하였다. Na+은 succinate의 이동을 증가시켜 overshoot 현상을 보였으며 이러한 효과는 K+, Li+, Rb+, choline 과 같은 다른 양이온들에 의해 나타나지 않았다. Na+농도변화에 따른 succinate의 이동율은 sigmoid모양을 보였고, Na+에 대한 Hill coefficient는 2.0이었다. soccinate의 이동은 vesicle 내부가 음전압일 때 더욱 증가되었다. BLMV에서...
