The effects of renal ischemic preconditioning (RIP) on ischemia-reperfused myocardium were examined in the urethane-anesthetized rabbit to determine whether RIP may provide cardioprotection and to observe the role of the renal nerve in such condition. The results obtained are as follows: (1) During 45 min myocardial ischemia and subsequent 180 min(More)
The effects of capsaicin microinjection into area postrema (AP) on mean arterial pressure (MAP), heart rate (HR) and renal sympathetic nerve activity (RSNA) were investigated in 36 anesthetized Sprague-Dawley rats. The results obtained are as follows. (1) Following microinjection of capsaicin (10 micromol/L, 50 nl) into the AP, MAP, HR and RSNA were(More)
The effects of ischemia-reperfusion (IR) and ischemic preconditioning (IP) on hemodynamics, epicardial electrography, myocardial infarct size, cardiomyocytic apoptosis and gene proteins involving apoptosis (Fas, Bcl-2 and Bax) were observed in aneasthetized rabbit myocardium. The results are as follows. (1) During ischemia-reperfusion, heart rate, arterial(More)
Effects of adenosine (Ado) on spontaneous and glutamate induced discharges of neurons in CA1 area of hippocampal slices were examined using extracelluar recording technique. The results are as follows. (1) In response to the application of Ado (0.01 0.1 micromol/L, n=20) into the superfusate, spontaneous discharge rates (SDR) of 20 neurons decreased(More)
Sarcandra glabra was a renowned herb traditionally used as herbal tea or food supplement to enhance mental efficiency and to recover from stress or fatigue in China. We investigated the effects of Sarcandra glabra extract (SGE), with chemical composition clearly showed by HPLC fingerprint as quality control, on immunologic response including natural killer(More)

To observe the effect of intracarotid administration of endothelin (ET-1) on electrical activity of neurons within rostral ventrolateral medulla (RVLM) region, 87 spontaneous active units were extracellularly recorded in 35 Sprague-Dawley rats with sino-aortic denervation. The results obtained are as follows. (1) Intracarotid administration of ET-1 (0.3(More)

To observe the effect of intracarotid administration of adenosine on neurons in the rostral ventrolateral medulla (RVLM) region, 72 spontaneous active units were extracellularly recorded from 28 Sprague-Dawley rats with sino-aortic denervation. The results obtained are as follows: (1) intracarotid administration of Ado (25 micrograms/kg) reduced the(More)
Using extracellular recording technique, the effects of L-arginine (L-arg), N-nitro-L-arginine (L-NNA), SIN-1 and methylene blue (MB) on spontaneous discharges of neurons in CA1 area of hippocampal slices were examined to determine the role of L-arg: NO pathway and the possible underlying mechanism. The results were as follows: (1) In response to the(More)

UNLABELLED The effects of m-nisoldipine (m-Nis) and nisoldipine (Nis) on action potentials of papillary muscles in guinea pigs were studied using intracellular microelectrodes. THE RESULTS (1) APD and Vmaxs in normal papillary muscles were reduced by m-Nis and Nis. However, the APA, Vmaxf and overshoot were not affected. (2) In the partially depolarized(More)
The present study was conducted to investigate the effects of histamine on the lipid metabolic disorder in mice loaded with restraint stress. When Kun Ming (KM) mice were exposed to restraint stress for 20 h, the histamine level in both plasma and cerebral regions significantly increased (P<0.01). Moreover, when a lipid emulsion (10% Intralipid) was(More)
