OBJECTIVE: To compare effects of Phellodendron chinense, stir-baked P. chinense with yellow rice wine and stir-baked P. chinense with salt solution on thyroid gland and adrenocortical function of kidney-Yin deficiency model rats with hyperthyroidism. METHODS: 88 rats were randomly divided into blank group, model group, yellow rice wine group, salt solution group, positive group (Liuwei dihuang pills, 0.2 g/kg, calculated by crude drug), high-dose and low-dose groups of P. chinense, stir-baked P. chinense with yellow rice wine and stir-baked P. chinense with salt solution (9.519, 1.058 g/kg, calculated by crude drug). Except for blank group, other groups were given levothyroxine sodium to induce kidney-Yin deficiency model; during modeling, treatment groups were given relevant medicine intragastrically, and other groups were given constant volume of solution intragastrically, once a day, for consecutive 3 weeks. After last administration, body weight, 24 h urine amount, viscera (thymus, spleen) indexes were determined; the serum levels of free triiodothyronine (FT3), free thyroxine (FT4), vasopressin (AVP), cAMP and cGMP were determined as well as urine levels of 17-hydroxy steroid (17-OHCS). cAMP/cGMP ratio was also calculated. RESULTS: Compared with blank group, body weight, 24 h urine amount and viscera (thymus, spleen) indexes were decreased significantly in model group; serum levels of FT3, FT4, AVP and cAMP, cAMP/cGMP ratio and urine level of 17-OHCS were increased significantly, while serum level of cGMP was decreased significantly, with statistical significance (P<0.01). Except for the body weight in stir-baked P. chinense with yellow rice wine group and the serum level of cGMP in high-dose and low-dose of stir-baked P. chinense with yellow rice wine group, above indexes of positive group, high-dose and low- dose groups of P. chinense, stir-baked P. chinense with yellow rice wine and stir-baked P. chinense with salt solution were all improved significantly (P<0.05 or P<0.01). The improvement degree order was as follows as stir-baked P. chinense with salt solution>P. chinense>stir-baked P. chinense with yellow rice wine. Serum level of cAMP and cAMP/cGMP ratio in stir-baked P. chinense with salt solution high-dose group and serum levels of 17-OHCS in stir-baked P. chinense with salt solution high-dose and low-dose groups were significantly lower than in same dose group of P. chinense. CONCLUSIONS: P. chinense can improve thyroid gland and adrenocortical function of kidney-Yin deficiency model rats with hyperthyroidism , which can be enhanced by stir-baked with salt solution but attenuated by stir-baked with yellow rice wine. It indicates that Yin-nourishing effect of P. Chinese have been enhanced after stir-baked with salt.
