ABSTRACT

4-Mercuric acetate estrone (4-MF1) is one of steroidal estrogens which have hi-her protective and therapeutic effects on dogs receiving 2.75 Gy of 60Co ?-ray iradiation.Among those experimental groups,the group treated with 4-ME1 15 mg i.m. two days before irradiation had the higest protective effect, all 5 dogs survived;The group treated with 4-ME 1 i.m. twice at 6,48 h after irradiation had the best therapeutic effect. The survival rate was elevated 54.4%(9/15), as compared with the control group.The clinical symptoms were milder, survival time of dead animals longer, and the WBC count higher.
