The main foundation that changes the simulation nephrasthenia syndrome with the animal adrenal gland cortex hormone function is that clinical insufficiency of kidney-YANG patient shows as hypoadrenocorticism, deficiency of the kidney yin patient clinical manifestation has hyperinterrenal phenomenon, and adrenocortical hormone also obviously increases in aging course.In addition, clinical in treatment needs to use the adrenocortical hormone patients to show as deficiency of the kidney yin for a long time in a large number, hormone shows as insufficiency of kidney-YANG after stopping using.According to above result, designed the method for application adrenocortical hormone preparation " nephrasthenia syndrome " animal model.It is the modeling method of present widely used animal nephrasthenia syndrome that animal gives the modeling method that adrenal gland's glucocorticoid prepares nephrasthenia syndrome.In big quantity research, the animal applications 17-hydroxy-11-dehydrocorticosterone phase is " deficiency of the kidney yin ", and the back of stopping using is " insufficiency of kidney-YANG ".The exogenous corticosterone that this institute adopts is handled the method that mice was made " deficiency of the kidney yin " model in 7 days, obtains scholar's approval substantially, and has been used by lot of documents.

This experimental result shows, orally give LWD-b to female " deficiency of the kidney yin " model mice ovary weight due to the adrenocortical hormone reduce, the reduction of serum E2 and hypophysis LH level also has obvious improvement effect; Decline to male " deficiency of the kidney yin " mice serum testosterone levels also has obvious improvement effect, and low or dysequilibrium has obvious improvement or regulating action to " deficiency of the kidney yin " HPG s function that mice showed to show LWD-b.The The above results prompting, LWD-b to HPG s function due to the deficiency of the kidney yin low or balance disorderly all have improve or regulating action, clinically can be used for aging and with the low disease of HPG s function of syndrome of deficiency of kidney yin such as climacteric syndrome, ovarian hypofunction, infertility, habitual abortion, autonomic nervous dysfunction, chloasma, gynaecomastia, senile deterioration, climacteric osteoporosis, prevention such as senile osteoporosis and treatment.
