GS354와 GS389의 세포내 칼슘{[Ca2+]1: Fura-2의 형광으로 측정}과 근장력 변화에 대하여 백서의 흉부동맥을 사용하여 검토하였다. GS354와 GS389 모두 고농도의 포타슘과 노어에피네프린에 의한 수축을 억제시켰다. GS354의 헐관이완은 [Ca2+]1의 감소가 동반되었고 고농도의 포타슘에 의한 [Ca2+]1증가억제 현상도 칼슘통로 활성제인 Bay K8644에 의하여 길항되었다. 그러나 혈관이완 작용은 Bay K8644에 의해 억제 되지 않았다. 이러한 사실은 GS354는 칼슘통로를 차단하여 [Ca2+]1을 감소시키며 또한 수축기구에 대한 칼슘의 감수성을...

본 연구에서는 세포내의 칼슘이온과 결합하여 형광을 발하는 형광색소 fura 2를 이용하여 세포내의 칼슘이은 농도를 측정함과 동시에 장력을 측정하였으며 이에 대한 카페인과 고농도의 칼륨의 영향을 정토하였다. 72.7 mM의 칼륨 이온은 장력과 세포내 칼슘이온농도에서 각각 지속적 인 증가를 보여주었으며, 20 mM의 카페인은 일과성의 빠른 세포내의 칼슘이은농도의 증가에 이어 감소를 보여주었으나 기본치 보다는 높았다. 그러나, 장력에 있어서는 카페인은 일과성의 증가에 이어 기본 장력보다 낮은 감소를 보여주었다. 한편...

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...

This study evaluated the hypothesis that motoneuron collaterals modulate the excitability of ventral spinocerebellar tract neurons. In acute cats, 128 ventral cerebellar tract cells were studied extracellularly to determine the effects of ventral root stimuli. The majority of the cells responded to ventral root stimulation with either short or long latency increases in spike discharge. In many cells with sufficient spontaneous activity ventral root stimulation also evoked a long lasting...

This study was aimed to elucidate the changes in heart rate variability during treadmill exercise at various speeds and grades by spectral analysis. Thirty-three untrained male college students aged 20 ~ 26 yr were employed to exercise on a treadmill using 4 speeds (4.02, 5.47, 6.76 and 8.05 km/h) and 6 grades (0, 4, 8, 12, 16 and 20%). A fixed speed was selected for each session with the grade increased every 3 min. The electrocardiogram, respiration and the stepping activity were continuously...

In the present study, the relationship between the somatosympathetic reflexes and arterial blood pressure responses to electrical stimulation of the peripheral nerve was investigated in cats anesthetized with α-chloralose. Single sympathetic postganglionic fiber activities were recorded from the hindlimb muscle and skin nerves and also from the cervical and abdominal sympathetic chains. Effects of the morphine on responses of the sympathetic nerve and arterial blood pressure to activation of...

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...

level at 24 hr. On the other hand, angiotensinogen mRNA levels il the hypothalamus and brainstem were continuously increased from 2 to 24 hrs. The present study demonstrates the presence of angiotensinogen mRNA in both hepatic and extrahepatic tissues, and more importantly, their up-regulation after hemorrhage. These results suggest that the angiotensinogen-generating systems in the liver, kideny and brain are, at least in part, under independent control and play a local physiological role.
