[Mechanisms about the effect of different acupuncture manipulation methods on body temperature].

Objective: To introduce studies about the effect of different needling manipulation methods on the body surface temperature in recent years, and to probe the mechanism.

Methods: It is reviewed from clinical studies and experimental studies, and other aspects.

Conclusion: The functions and therapeutic effects of acupuncture are changed with temperature changes induced by different needling manipulations.

Adrenomedullin reduces intracellular calcium concentration in cultured hippocampal neurons.

The effects of adrenomedullin (ADM) on intracellular calcium concentration ([Ca(2+)](i)) were investigated in cultured hippocampal neurons. Changes in [Ca(2+)](i) were detected by laser scanning confocal microscopy using Fluo 3-AM as the calcium fluorescent probe. [Ca(2+)](i) was represented by relative fluorescent intensity.

[Effect of intracerebroventricular injection of adrenomedullin on catecholaminergic neurons and expression of c-fos in the rat brain nuclei involved in cardiovascular regulation].

Aim And Methods: Using double immunohistochemical method for Fos and tyrosine hydroxylase(TH) to examine the effects of intracerebroventricular (icv) administration of adrenomedullin (AM) on catecholaminergic neurons and the expression of c-fos gene in rat brain nuclei involved in cardiovascular regulation in order to define whether the effects of central administration of adrenomedullin (AM) were induced by activating the catecholaminergic neurons.

Results: (1) Following icy administration of AM (3 nmol/kg), Fos-like immunoreactivity neurons were markedly increased in several brain areas of the rat, including the brainstem, the hypothalamus and the forebrain. (2) Following icy administration of AM (3 nmol/kg), double-labeled neurons for Fos and TH increased significantly in the area postrema (AP), the nucleus of the solitary tract (NTS), the nucleus paragigantocellularis lateralis (PGL) and the locus coeruleus (LC).

Effects of agmatine on the electrical activity of subfornical organ neurons.

The aim of this study was to investigate the effects of agmatine (Agm) on the electrical activity of neurons in subfornical organ (SFO) slices using extracellular recording technique. The results are as follows. (1) In response to the application of Agm (1.

Intracerebroventricular administration of adrenomedullin increases the expression of c-fos and activates nitric oxide-producing neurons in rat cardiovascular related brain nuclei.

To define the action sites of adrenomedullin (ADM) in the rat brain, and to examine whether neuronal NO may participate in the actions of ADM, the present study was undertaken to examine the effects of i.c.v.

[A simple and new type of drop recorder mainly applied in the experiment of frog heart].

Aim: To introduce the manufacture and use of a simple, new type of drop recorder of frog heart.

Methods: To improve the perfusion device of (see text for symbol) and Straub method. Two electrodes of drop recorder were fixed in an injector of 20 ml.

Effect of intracarotid administration of adrenomedullin on the spontaneous electrical activity of area postrema neurons in sino-aortic denervated rats.

To observe the effect of intracarotid administration of adrenomedullin (AM) on the spontaneous electrical activity of area postrema (AP) neurons, 78 spontaneous active units were recorded from 63 sino-aortic denervated Sprague-Dawley rats using extracellular recording technique. The results obtained are as follows. (1) Following intracarotid administration of AM (0.

Microinjection of adrenomedullin into rostral ventrolateral medulla increases blood pressure, heart rate and renal sympathetic nerve activity in rats.

The present study was undertaken to examine the effects of microinjection of adrenomedullin (AM) into rostral ventrolateral medulla (RVLM) on mean arterial pressure (MAP), heart rate (HR) and renal sympathetic nerve activity (RSNA) in 34 anesthetized Sprague-Dawley rats. The results obtained are as follows. (1) Following microinjection of AM (10 micromol/L, 200 nl) into the RVLM, MAP, HR and RSNA were significantly increased from 99.
