Research on the establishment of chronic stress-induced premature ovarian failure the rat model and effects of Chinese medicine Muniziqi treatment.

The purposes of this study were to establish and to explore the biological basis of the chronic stress-induced premature ovarian failure (POF) model and to explore the therapeutic effects of the traditional Chinese medicine Muniziqi. Sexually matured female Sprague-Dawley rats were fed with spinach and cilantro in cold and wet conditions for about 20 weeks until a chronic stress (CS) model was established. The CS rats were divided into a POF stress model group and a stress model group according to weekly biological characteristics and hormone level detection ( luteinizing hormone [LH], follicle stimulating hormone [FSH], and estrogen [E2]). To investigate the therapeutic effect of Muniziqi, the POF disease stress model group was divided into the high-, medium-, and low-drug intervention groups. The results showed that chronic stresses (special food, cold, damp) can lead to POF disease. The traditional Chinese medicine Muniziqi could not only improve the reproductive hormone level disorder, but also improve the function of the hypothalamus-pituitary-ovarian axis. The underlying mechanism may be a change in the E2, LH, and FSH hormone levels in serum and lower expression of ovarian premature aging-related protein PFN-1.

Research on Establishment of Abnormal Phlegmatic Syndrome with Premature Ovarian Failure Rat Model and Effects of Balgham Munziq Treatment.

This study aimed to establish and explore the biological basis of abnormal phlegmatic syndrome with premature ovarian failure (POF) model in rats based on the Uighur medicine (UM) in the first place and investigate the effects of unique herbal medicine, Balgham Munziq (BMq). Mature female Wistar rats were fed with spinach and coriander in cold and humid condition for approximately 20 weeks until abnormal phlegmatic syndrome (APS) model was established. When APS model was confirmed by Uighur medical experts, APS with POF disease rats were subdivided into APS with POF disease model group and APS with POF disease treated with BMq group; the rest of them were subdivided into APS model group and APS treated with BMq group. The results show that biological characteristics of animals in the course of modeling period were in accordance with clinical features of abnormal phlegmatic syndrome (APS) in Uighur medicine. Herbal medicine BMq not only reverted reproductive hormone levels disorders but also improved the function of hypothalamic-pituitary-ovarian axis and regulated secretion of monoamine neurotransmitters. APS is most likely to cause pathological changes of hypothalamic-pituitary-ovarian axis and lead to the occurrence of POF and BMq is effective in the treatment of APS with POF disease.
