[Research on osteoporosis model rats with kidney deficiency syndrome]

To observe general conditions, physiological condition, viscera wet weight and kidney asthenia serological index in osteoporosis model rats established by bilateral ovarian resection, and provide basis for treating osteoporosis by invigorating kidney.

Twenty-four female SD rats were randomly divided into 3 groups as model group, sham group and normal group. After anesthesia,model group were treated by bilateral ovarian resection, sham group by sham operation, and normal group without any processing. Pathological tissue and bone mineral density (BMD) of femur was performed 3 months postoperatively. The general conditions and physiological conditions were processed after successfully modeling. Electronic balance was used to collect the weight of kidney, drenal, pituitary, and uterus. Estrogen (E2), Adrenocorticotropic hormone (ACTH), Three typical thyroid original acid (T3), Four typical thyroid original acid (T4) were detected by ELISA.

Osteoporosis model appeared with syndromes of kidney deficiency, such as body hair without burnish, chills, cluster, sluggishness, eyes dark, eye movement slow, slow to respond to the delay, decreased appetite, activities slow, body fat, and drowsiness, defecate slightly thin andclear abundant urine. Mobility, anal temperature and food-intake were lower than normal and sham group; the level of ACTH, E2, T3, T4 lower than sham and normal group; the weight of kidney, drenal, pituitary, and uterus also lower than other two groups.

Osteoporotic model rats, established by bilateral ovarian resection, have manifestation of organic and functional performance of kidney deficiency. Therefore, osteoporotic model rats have the pathogenesis of kidney asthenia and clinical manifestations of kidney deficiency.
