Objective To observe the expression of neuron apoptotic protein caused by whole body gyperthermis (WBH) in rats anesthetized using propofol and chloral hydrate,and to explore the pathway of any hippocampal neuron apoptosis induced by WBH. Methods Sixty-three male Wistar rats were randomly divided into 3groups,21 in each group.One guoup received neither anesthesia nor WBH treatment sa a control (group A);group B were anesthetized with an intraperitoneal injection of 100 mg/kg of propofol;group C receivde a similar injection of chloral hydrate. This was followed by WBH (keeping the rats' core temperature at 42°for 30 min) for all three groups. The rats'brains were then removed 24 h after WBH to separate the ghpplcampal CA1,CA2 zones and the dentate gyrus regions.Any neuron apoptosis was detected using the TUNEL methol;Bax/Bcl-2/caspase-3 protein expression was measured with a SABC immmunogistochemical technique;and the changes in ultrastructure were observed tith an electron microscope. Results Compared with group A,the changes in the ultrastructure of neurons in the hippocampus changed after WBh were the most severe in group C.The changes included edema of the organelles,vacuolization of mitochondria,rarefaction of the endocytoplasmic reticulum,incopleasmic reticulum,incomplete synaptic membranes and autophagy.Both the number of apoptotic neurons and the expression of Bax and capase-3 protein in the hippocampus increased in the following order: group A<group B<group C.Expression of Bcl-2 protein in the hippocampus increased in the following order: group A<group C<group B. Conclusion Hippocampal apoptosis induced by WBh involves upregulating the expression of Bax and caspase-3 and downregulating the expression of Bcl-2.

Prion diseases are infectious and fatal neurodegenerative diseases. The pathogenic agent is an abnormal prion protein aggregate. Microglial activation in the centre nervous system is a characteristic feature of prion disease. In this study, we examined the effect of PrP 106-126 on PrP mRNA gene expression in Mouse microglia cells BV-2 by real-time quantitative PCR. PrP mRNA expression level was found to be significantly increased after 18 h exposure of BV-2 cells to PrP 106-126, with 3-fold increase after 18 h and 4.5-fold increase after 24 h and BV-2 cells proliferating occurred correspondingly. Our results provide the first in vitro evidence of the increase of PrP mRNA levels in microglial cells exposed to PrP 106-126, and indicate that microglial cells might play a critical role in prion pathogenesis.

This study is designed to investigate the effects of chinfloxacin hydrochloride (CFX) on the kinetics of HERG K+ channel. Whole cell patch clamp technique was used to record HERG K+ currents from HEK293 cells transiently transfected with cgi-HERG-GFP plasmids and channel kinetics were assessed in the absence and presence of CFX and moxifloxacin hydrochloride (MOX). Results demonstrated that the open state of HERG K+ channel was inhibited by CFX in a concentration- and time-dependent manner, with an IC50 of 162.1 +/- 14.2 micromol x L(-1), two folds higher than its positive control MOX. But there were no significant effects on channel kinetics. In addition, the inhibitory effect of CFX on HERG was enhanced when cells were subjected to altered extracellular K+ concentration.
