[In vivo study of antifertility and anti-inflammatory effects of compound Kucen gel].

Abstract

OBJECTIVE:

To study the antifertility and anti-inflammatory effects of compound Kucen gel in vivo.

METHODS:

As antifertility experiment, we randomly divided 60 female SD rats into six groups of equal number: normal saline, blank gel, low-, medium- and high-dose compound Kucen gel (0.05, 0.10 and 0.15 g/g), and positive control (4% nonoxynol gel) to receive intravaginal administration of 200 microl of respective agent, followed by copulation with male rats in a 1:1 ratio. At 12 days after successful mating, the female rats were dissected for calculation of the embryos and the rate of contraception. As an anti-inflammatory trial, we established a mouse model of inflammation by applying xylene to the pinna, and equally randomized 60 Kunming mice to six groups as in the former experiment. We determined the degrees and average rates of swelling inhibition in the left ear.

RESULTS:

High-dose compound Kucen gel achieved a fertility-inhibition rate of 100% in the female rats, the number of embryos significantly lower than in the normal saline group (0.00 +/- 0.00 vs 11.00 +/- 2. 00, P < 0.05), but with no statistically insignificant difference from that of the positive control (0.00 +/- 0.00, P > 0.05). High-dose compound Kucen gel also markedly suppressed swelling in the left ear of the mice, with an inhibition rate of 52.3%, the average swelling degree significantly lower than in the normal saline group (10.17 +/- 2.56 vs 21.32 +/- 3.17, P < 0.01), but not remarkably different from that of the positive control (8.53 +/- 1.89, P > 0.05).

CONCLUSION:

Compound Kucen gel, with its strong antifertility and anti-inflammatory effects, deserves further study and clinical application.
