中药药膜加微波照射对实验性大鼠乳腺增生的影响

目的 观察中药药膜、微波照射和药膜加微波照射对乳腺增生病的预防和治疗作用。方法 采用苯甲酸雌二醇配合应用少量黄体酮肌肉注射，建立乳腺增生病大鼠模型。于造模后2周外敷药膜和微波照射，并于给药和照射前后测量大鼠第2对乳头直径，放免法测定血清雌二醇(E2)、孕酮(P)和催乳素(PRL)浓度，镜下观察乳腺增生的病理改变，计算乳腺增生率。结果 中药药膜能显著降低实验性大鼠乳腺增生程度，抑制乳腺增生，乳腺增生率分别为23．4％和20．9％，并可调节E2和P浓度，降低PRL水平，病理组织学结果提示中药药膜组和药膜加照射组可明显减轻乳腺增生。结论 中药药膜外敷和药膜外敷加微波照射能降低乳腺增生程度，具有一定的防治乳腺增生病的作用。

Effect of Chinese Herbal Medicine Film & Microwave Irradiation on Experimental Mammary Hyperplasia in Rats

Objective To observe the preventive and therapeutic effect of Chinese herbal medicine film µwave irradiation on mammary hyperplasia in rats. Methods Rat models of experimental mammary hyperplasia were established by intramuscular injection of estrogen and a small quantity of progestin. Two weeks after modeling, the rats were treated with Chinese herbal medicine film µwave irradiation. Before and after the treatment, mammary diameter of the second nipples were measured, serum concentrations of estrogen (E2), progesterone (P) and prolactin (PRL) were determined by radioimmunoassay,pathological changes of mammary hyperplasia were examined under microscope,and the rate of mammary hyperplasia was measured. Results Chinese herbal medicine film markedly inhibited experimental mammary hyperplasia in rats,and the rate of mammary hyperplasia were 23.4 %in medicine film group and 20.9 %in medicine film µwave irradiation group respectively. Medicine film regulated the concentrations of estrogen and progestin,reduced the level of PRL and alleviated the pathological severity of mammary hyperplasia obviously. Conclusion Chinese herbal medicine film µwave irradiation have certain preventive and therapeutic effect on mammary hyperplasia in rats.
