Study on Effect of Gypsum and Baihu Decoction on Reducing Fever and the Na/Ca Ratio in Sera of Febrile Rats Induced by Dried Yeast
石膏及白虎汤的清热作用与对血清Na/Ca比值影响的实验研究

This work studied the effect of gypsum and Baihu Decoction on reducing fever and on the Na/Ca ratio in sera of febrile rats induced by dried yeast. The rat pyrexia models were established by injecting dry yeast hypodermically. Sera were collected at three different time points. The content of Na and Ca was determined by ICP-OES, and the ratio of Na/Ca was calculated. Gypsum and Baihu Decoction significantly reduced fever of febrile rats induced by dried yeast, and the Na/Ca ratio of the Baihu Decoction group went down after intragastric administration. The result showed that the functioning mechanism of gypsum and Baihu Decoction to reduce fever may be associated with reduction of the Na/Ca ratio.
