RESUMO
<p><b>OBJECTIVE</b>To observe the effects of Modified Wenjing Decoction (MWJD) on the ovarian oxidative damage of cold coagulation blood stasis (CCBS) model rats, thus consummating the action mechanisms of MWJD for treating gynecopathy of CCBS syndrome.</p><p><b>METHODS</b>Female SD rats were randomly divided into the normal group, the model group, and the treatment group. Rats in the model group and the treatment group were placed in the ice water (0 -1 degrees C) to establish the rat model of CCBS syndrome. Meanwhile, MWJD was given by gastrogavage to rats in the treatment group for 2 weeks. Rats were decapitated during the oestrous cycle. The serum levels of estradiol (E2), progestone (P), testosterone (T) were detected. The bilateral ovarian tissues were taken out and operated on ice. The total bilirubin (TBIL), superoxide dismutase (SOD), malondialdehyde (MDA), total antioxygen capacity (T-AOC) were detected after homogenate.</p><p><b>RESULTS</b>Compared with the normal group, serum levels of E2, P, T, and ovarian levels of TBIL, SOD, T-AOC all obviously decreased in the model group, and the ovarian MDA level increased, showing statistical difference (P <0. 05, P <0.01). After treated by MWJD, when compared with the model group, serum levels of E2, P, T, and ovarian levels of TBIL, SOD, T-AOC increased, the ovarian MDA level decreased, showing statistical difference (P <0.05, P <0.01). All indices except serum T level and the ovarian MDA content restored to the normal levels (all P>0.05).</p><p><b>CONCLUSIONS</b>The ovarian functions are abnormal in CCBS model rats. MWJD could restore the ovarian functions by improving the ovarian oxidative damage state, thus treating gynecopathy of CCBS syndrome.</p>
