Rat glioma cell C6 was infected by the deficiency recombinant retrovirus (named C6TK). The sensitivity of C6TK cells to GCV or ACV increased 450 or 10 times than that of C6 cells respectively. Rat C6 glioma model was successfully built, and SD rats inoculated intracerebrally C6TK cells had normal gliomas. The average survival periods of the rats were about 15 days. However, after treated with ACV, the growth of C6TK tumors obviously regressed, and the survival periods extended to 57.8±8.1 days, especially in rats injected with mixed PA317TK and C6 cells or in situ PA317TK cells, which the tumors nearly disappeared after ACV administration and the survival periods extended to over 120 or 71.4±36.1 days respectively, P＜0.001.

Immunohistochemical localization of inhibin α-subunit in normal mature rats was carried out by using Strept Avidin-Biotin-Peroxidase Complex .The results showed that there was positive immunoreactivity of the McAb to inhibinα-subunit in heart ,kidney , spleen , lymph ,adrenal gland and pancreas cells. It indicated that inhibinα-subunit existed in the above tissues , But no positive sites were seen in hypothalamus, pituitary, lung and liver, that means they have no inhibinα-subunit. Compared with the ovariectomized rats, the hypothalamus and pituitary of the rats injected with inhibin-α fragment（1～32）showed an positive reaction, suggesting that inhibin α-subunit could pass through the blood-brain barrier .
