The Ethanolic Extracts The Gorgonian Isis hippuris Inhibited the Induced Mammary Carcinoma Growth In C3H Mice

Abstract

The gorgonian Isis hippuris contains secondary metabolites gorgosterol and hippuristanol which are capable of inhibiting cancer cells. However, in vivo test of the gorgonian Isis hippuris extract as the anticancer drug has not been conducted. The research to study of the effect of ethanolic extract of the gorgonian on the induced tumor growth in C3H mice. The I. hippuris was obtained from Karimunjawa water in Jepara. The extract was prepared by maceration using ethanol. A total 20, 8-10 moths old of C3H mice with an initial weight of 20- 25 gram were assigned into control, Ih-1, Ih-2, and Ih-3 groups. Control, Ih-1, Ih-2, and Ih-3 groups each received 0, 0.15, 1.5, and 15 mg extract per mouse per day respectively for two weeks. Cancer cells were introduced to all groups from a donor cancer mouse by injection via left or right axilla and allowed to grow. The cancer mass was removed and processed for histological examination, and cancer growth was determined according to Elston and Ellis criteria. The result showed that histological grade of cancer mass from the control group was in grade 2 or differentiated moderately. The histological grade of cancer mass from Ih-1, Ih-2, and Ih-3 groups were in grade 1 (low grade) or similar to a normal cell. Statistical analysis by Kruskal-Wallis test showed a significant difference (p<0,05) between control and treated mice. Mann-Whitney test found no significant differences among Ih-1, Ih-2, and Ih-3 treated mice. The results indicated the potential of active substances in the ethanol extract of I. hippuris as an anticancer drug.
