Objective: To investigate the alteration of bcl- 2 gene family in the rat brain and the molecular mechanism of neuronal apoptosis following traumatic brain injury. Methods: Male Sprague -Dawley rats were subjected to lateral fluid percussion brain injury(FPI) of mo derate severity. Bcl-2, Bcl-x and Bax protein expression was detected by immun ohistochemistry. Results: (1) The immunoreactivity of Bcl-2 and Bcl-x protein decreased in the hippocampus ipsilateral impact site as early as 6 h post-injury, and this was the main cause of down-regulation of the ratio of Bcl-2+Bcl-x to Bax. (2) During 1-3 d after injury, the Bax protein express i on increased significantly, while the Bcl-2 and Bcl-x protein expression decre ased relatively slow. The decreased ratio of Bcl-2+Bcl-x to Bax was mainly due to the Bax up-regulation. Conclusion: The bcl-2 gene family is involved in neuronal apoptosis after FBI, and the protein expression alteration of the family members leads the neuronal cell to apoptosis.

Objective: To investigate the alterations of bcl-2 gene family in the rat brain and the molecular mechanism of neuronal apoptosis follow ing traumatic brain injury (TBI). Methods: Male Sprague-Dawley rats were subjected to lateral fluid percussion brain injury(FPBI) of moderate severity. bax and bcl-xL mRNA and protein expression was detected by RT-PCR an d immunohistochemistry. In addition to morphological evidence of apoptosis, TUNE L histochemistry was used to identify DNA fragmentation in situ under both l ight and electron microscope, whereas characteristic internucleosomal DN A fragm entation of apoptosis was demonstrated by DNA gel electrophoresis. Resul ts: bcl-xL mRNA and protein decreased in the ipsilateral hemisphere t o the impact site as early as 6 h post-injury[(67.42±7.54)% and (85.85±5.72)% r espectively]. The decrease in bcl-xL mRNA and protein preceded apoptosis was observed 12 h post-injury. And this was the main cause of up-regulation of the ratio of bax to bcl-xL in the acute period(minutes-hours) followin g FPBI. bax mRNA and protein were observed to rise slowly, doubled 3 d post- injury, returned to sham level slowly. The delayed cell death (days-weeks) migh t associated with the up-regulation of pro-apoptotic gene bax. Conclusio n: The expression of bcl-xL and bax coincide with apoptosis following TBI. The reg ulation of bax and bcl-xL by TBI occur before transcription. The balance of bax/bcl-xL ratio determines the neurocytes to survive or die following FPBI.

Epmedii Folium is a commonly used traditional Chinese drug, and is beneficial for the "liver" and "kidney" s function in Chinese medicine. Recently, the origin of this drug is more complex. Most of the identification studies are emphasized on the species certified by the pharmacopoeia and other related species from the same genus of Epimedium, but few was emphasized on the counterfeit. In this paper, one counterfeit of Epmedii Folium, identified as the dried leaf of Quercus variabilis (Fam. Fagaceae), has been reported based on field investigation, comparing specimen of Epmedii Folium and Q. variabilis,using the macroscopic, microscopic and TmC methods. It is resulted that they could be identified clearly not only by the macroscopic features, such as the vein character and the tooth apex, but also by the microscopic features, such as the vascular bundles of the midrib, the non-glandular hair, the anticlinal wall of the epidermis cell and the calcium oxalate crystal. Furthermore their TLC chromatograms showed also difference. This study will give reference for the identification of Epmedii Folium and the related supervision and inspection work.
