Urethane 마취 가토에서 뇌내 alpha-1및 alpha-2 adrenoceptor의 작용에 미치는 calcium antagonist의 영항을 알아보고자 뇌실내 methoxamine과 clonidine의 혈압및 심박수 변동에 미치는 diltiazem, nifedipine의 영향을 조사한 결과, 1). 뇌실내 methgramine(1mg)은 혈압상승및 심박수 감소를 일으켰고, 뇌실내 clonidine(30μg)은 혈압하강및 심박수 감소를 일으켰다. 2). 뇌실내 diltiazem과 nifedipine은 dose-dependent한 혈압하강을 일으켰으며 심박수 감소를 일으켰다. Diltiazem에 비하여 nifedipine은 혈압하강 효과는 크고...

Excitatory amino acids (EAA) are thought to play an important role in producing cell death associated with ischemic and traumatic spinal cord injury. The present study was carried out to determine if the response characteristics of spinal sensory neurons in segments adjacent to degeneration sites induced by EAA are altered following these morphological changes. Intraspinal injections of quisqualic acid (QA) produced neuronal degeneration and spinal cavitation of gray matter. The severity of...

Chronic exposure to cadmium impairs various renal tubular functions, including organic acid (anion) secretion. To investigate the mechanism of cadmium-induced alterations in the organic anion transport system, kinetics of p-aminohippurate (PAH) uptake was studied in renal cortical basolateral membrane vesicles (BLMV) isolated from cadmium-intoxicated rats (adult male Sprague-Dawley). Cadmium intoxication was induced by subcutaneous injections of CdCl2 (2 mg Cd/kg per day) for 3 weeks. The renal...

The aim of present study was to characterize phosphate uptake and to investigate the mechanism for the insulin and insulin-like growth factor(IGF) stimulation of phosphate uptake in primary cultured rabbit renal proximal tubule cells. Results were as follows : 1. The primary cultured proximal tubule cells had accumulated 6.68±0.70 nmole phosphate/mg protein in the presence of 140 mM NaCl and 2.07±0.17 nmole phosphate/mg protein in the presence of 140 mM KCl during a 60 minute uptake period....

Lateral giant (LG)-mediated escape response of crayfish is sensitized by natural traumatic events. Such sensitization has previously been shown to be associated with increased transmission between primary afferents and sensory interneurons at the cholinergic synapse of LG escape reflex circuit. In the present study, it was firstly investigated as to whether transmission is also altered at other synapses of the LG-escape reflex circuit by traumatic shock-induced sensitization. Evidence that...

The effects of prolactin and vasopressin on the regulation of amniotic fluid (AF) volume and its Na+ concentration ([Na+]) through the membrane surrounding the AF during increase in AF volume due to fetal urination， were studied. About 70% of AF volume was replaced with normal isotonic saline solution. Isotonic saline solution (0.5ml) containing Congored and LiCI was introduced into each amniotic sac. Vasopressin (25 ng/ml) or prolactin (1 mg/ml) of AF was then injected into experimental...

Captopril, an inhibitor of angiotensin converting enzyme, is also known to inhibit the degradation of bradykinin. We examined the effects of intracerebroventricular (ICV) captopril on the central pressor response to bradykinin in normotensive, 2-kidney, 1 clip Goldblatt (GHR) and deoxycorticosterone acetate (DOCA)-salt hypertensive rats. Captopril (1 mg) and bradykinin (5 nmol) were administered into the right lateral cerebral ventricle, and blood pressure and heart rate were continuously...

The present study was carried out to characterize the functional properties of spinomesencephalic tract (SMT) neurons in the lumbar spinal cord of urethane anesthetized rats. Extracellular single unit recordings were made from neurons antidromically activated by stimulation of the midbrain area, including the deep layers of superior colliculus, periaqueductal gray and midbrain reticular formation. Recording sites were located in laminae I-VII of spinal cord segments of L2-L5. Receptive field...

It is well known that chromaffin cells of adrenal medulla secrete catecholamine in response to sympathetic nerve activation and the influx of Ca2+ through the voltage dependent Ca2+ channels (VDCC) in the cell membrane do a major role in this secretory process. In this study, we explored the effect of divalent cations on VDCC of rat chromaffin cells. Rat (Sprague-Dawley rat, 150-250 gm) chromaffin cells were isolated and cultured. Standard giga seal, whole cell recording techniques were employed...

not. Between these two groups, rostro-caudal coordinate of the distribution from obex [4.7±0.2 (mean S.E.) mm, 4.1 0.1 mm], depth from dorsal surface (5.5±0.2mm, 4.9±0.1mm and conduction velocity (9.9±1.7m/sec, 16.7±1.9 m/sec) were significantly different (p<0.05). In spontaneously discharging group, characteristics of rostral and caudal groups were significantly different and we demonstrated that cells in rostral group mediate somatosympathetic reflex. From these results, we conclude that...
