혈압과 심박수의 중추조절에 대한 복외측 연수의 choline성 수용체의 역할을 규명하기 위하여 본 연구를 실시하였다. urethane으로 마취한 흰쥐에서 신경흥분성 아미노산인 L-glutamate(300 ng/site)를 복외측 연수에 미세주사하여 승압부위 (VLPA)와 감압부위 (VLDA)를 각각 기능적으로 확인하였다. VLPA와 VLDA에 각각 여러가지 choline성 약물들과 choline성 수용체의 길항제들을 양측으로 미세주사하여 다음과 같은 결과를 관찰하였다. 1. VLPA에 ca.bachol(300 ng/site)를 미세주사한 후 현저한 혈압상승 및 빈맥이 일어났으며, 이...

min. The electrocardiogram, respiration and the stepping activity were continuously recorded through an A/D converter system on the computer disk. Power spectra of heart rate variability (RRV) were obtained by use of a fast Fourier transform algorithm. The frequency domain was divided into 3 bands: VLF (0 ~ 0.04 Hz), LF (0.04 ~ 0.15 Hz) and HF (0.15 ~ 1.00 Hz). Heart rate was 74.4±2.1 beats/min at rest and showed a steady increase during treadmill exercise with increasing speed and grade up to...

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...

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 of thirty-three cells were identified as cardiovascular neurons. During one cardiac cycle, the mean discharge rate of the neurons was 1.96±0.29 and the peak activity was observed 45 ms after the systolic peak of arterial blood...

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...

of CNPB and CO2 inhalation. The degree of hyperventilation during CNPB at eupnea was estimated to be 63% of that during control ventilation and was significantly greater than zero (p<0.0001), which suggests an alveolar hyperventilation due to CNPB. These results suggest that the mechanical alterations associated with n decrease in lung volume could play an important role in ventilatory control independently of chemical regulation of breathing. Thus, exercise hyperpnea, which is associated with a...

It is well established that neurons in ventrolateral medulla play a key role in determining the vasomotor tone. The purpose of present study is to identify sympathetic related, medullospinal tract neurons in ventrolateral medulla and to show that these mediate somato-sympathetic reflex. Medullospinal tract cells were identified by antidromic stimulation to intermediolateral nucleus (IML) of the second thoracic (T2) spinal cord in anesthetized cats. Peripheral nerves were stimulated for...

of sympathetic nervous system in ventrolateral medulla is advocated recently, there are wide varieties on the location and function of them according to authors. Present study aimed to identify and characterize the medullospinal tract cells in rostral and caudal medulla of cats .which branch to the lateral horn of the upper thoracic spinal cord. Cats were anesthetized with α-chloralose. The upper thoracic spinal cord and floor of the IVth ventricle were exposed. Medullospinal tract cells in...

The rostral ventrolateral medulla (RVLM) has been established recently as a sympathoexcitatory area. The present study was conducted to investigate whether the somatosympathetic pressor and/or depressor responses are mediated through RVLM in cats anesthetized with α-chloralose. An occipital craniectomy was performed and ventrolateral medulla were stimulated either electrically or chemically to evoke changes in arterial blood pressure. And then the effect of lesions in the ventrolateral medulla...
