5 cm).The survival rates and the diminished rates of tumors in size were analysed comparatively.Results For small hepatocellular carcinoma,the diminished rates of tumor's size were higher in group PEI than that in group TACE and group CST,and higher in group RF than that in group TACE(P0.05).For large hepatocellular carcinoma,the diminished rates of tumor's size were higher in group TACE and group CST than that in group RF(P

The suppressive effects of cyclosporin A ( CsA ) made in China on immune function were studied in mice. CsA ( 25 and 50 mg/kg ig for 4 d ) caused a significant decrease of spleen plaque forming cell ( PFC ) in mice. At the dose of 25, 50 and 100 mg/kg ig for 4 d, CsA inhibited the production of hemolysin in a dose-dependent manner in mice immunized with SRBC. CsA ( 25, 50 and 100 mg/kg ig for 10d ) also markedly inhibited the delayed cutaneous hypersensitivity ( DCH ) induced by DNCB in mice. CsA 50 mg/kg ig for 14d prolongated survival time of cardiac grafts. The treatment with CsA could not reduce the clearance rate of iv charcoal particles as well as bone marrow cells in mice. There was no significant difference of immu-nosuppressive effect on PFC response between China-made CsA and Sandoz-made CsA

AIM: To investigate the dynamic changes of Nogo-A expression in ischemic infarct brain in rats. METHODS: The model of middle cerebral artery occlusion (MCAO) in 80 rats was established and expression of Nogo-A mRNA was measured by immunohistochemistry and hybridization. RESULTS: In the brain of MCAO rats, Nogo-A mRNA expression was decreased at the third day and increased significantly at the 7th day, and reached high level at the 21th day, then remained the high level to the 28th day. Nogo-A protein expression showed the same results. CONCLUSION: Expression of Nogo-A did not change in the early stage of MCAO, but increased significantly in the late stage of MCAO, suggesting that Nogo-A expression may play an important role in the nerve regeneration of brain ischemic injury.
