The effects of FPL andits three ingredients on growth of ovary,on micro-and ultra-structure andAlkaline phosphatase activity of endometrium,on structure andkeratinization rate of exfoliated cells in vaginal epithelium in mice,onmicrocirculation in rat and on uterine kinesis in rabbit were respectivelyobserved by the techniques of light and electron microscopes,histochemistry,microcirculation and organ cinetography.The results have confirmed themechanism of FPL for the sterility caused by ovary standstill and persistentcorpus luteum to be as follows:(1) a weak estrogen-like role which canprompt development of ovary,proliferation and secretion of endometrium andvaginal epithelium and cornification of exfoliated cells in vaginal epithelium;(2)enhancing AKP's activity of endometrium;(3)improving microcirculation;(4) exciting uterus.

The inflammation reaction hyperplactic stage and lymphatic nodular stage are of nonspecific morphological changes and should be diagnosed with the help of positive tuberculin test and obvious increase of adenosine deaninase ; tuberculous nodular stage has a great number of epithelioid cells,and Langhans cells, caseous necrosis stage is characterized by a great deal of necrotic tissue and debris,a small number of fragmented epithelioid cells, and mainly by antiacid bacteria fibrinous hyperplastic stage is featured by a few fibrous tissue, cells and mucous oweing to hardness to get puncture, which neans tuberculous restoration,and scar formation.

炎性增殖反应期非特异性形态学变化，需要结合结核抗体阳性和腺苷酸脱氨酶明显增高有助于诊断，结核结节期主要可有较多类上皮样细胞及郎罕氏细胞；而干酪样脓样坏死主要见大量坏死组织及碎屑、少数残碎不全类上皮样细胞，此期主要能查到抗酸菌为特征；纤维增殖期，抽出物难取，仅见少数纤维组织、纤维细胞和黏液间质为其特征，提示结核恢复、瘢痕形成所致。
