[Effects of di-zhen granules on catecholamine transmitter and gonadotropin of clamacteric rats with deficiency of yin brings about the interior heat-syndrome].

Fifteen-month-old Sprague-Dawley rats were given with some kinds of hot property of herb to produce model of Deficiency of yin brings about the interior heat-syndrome. The weight, water drinking volume, and body temperature of model rats were observed at the process of producing model and the treatment of di-zhen granules. Hypothalamic NE, DA and plasma NE, E concentration were determined by high-performance liquid chromatography, and serum E2, FSH, LH levels were determined by radioimmunoassay. The results were that after having been given the hot property of herbs for 2 weeks, the model rats increased water drinking volume and body temperature, which is similar to the appearance of patients with Deficiency of yin brings about the interior heat syndrome, and after having been treated with di-zhen granules, the water drinking volume and temperature of model rats decreased significantly (P < 0.01). The hypothalamic NE, DA, plasma NE, E, and the serum FSH, LH of the group treated with di-zhen granules were significantly lower than that of the model group and the normal group(P < 0.01). The results show that our model mentioned above possesses some characteristic features of the human climacteric syndrome which exhibits Deficiency of yin brings about the interior heat-syndrome. Di-zhen granules may regulate the function of GnRH neurons and other neurotic nucleus in hypothalamus, and then rectify the endocrine disorders of climacteric.
