ABSTRACT
[Objective] To observe the effect of combination of Rhizoma Coptidis (RC) and Fructus Evodiae (FE) in various proportions on rat models with heat syndrome. [Methods] Rat models with heat syndrome were set up by gastric infusion of Radix Codonopsis Pilosulae and Radix Astragali seu Hedysari. Fifty rats were allocated to five groups: normal control group (Group A), model group (Group B), model rats treated with RC and FE at the proportion of 6∶1 (Group C), model rats treated with RC and FE at the proportion of 2∶1 (Group D) and model rats treated with RC and FE at the proportion of 1∶1 (Group E). [Results] Ultrastructure of hepatic cells were improved in Group C, Group D and Group E. Indexes of heat syndrome such as temperature, serum corticosteroid (Cor) level and 17 - hydroxycorticosteroid (17-OHCS) content in homogenate of adrenal glands were decreased in Group C and Group D but stayed unchanged in Group E as compared with Group B ( P
