OBJECTIVE: To investigate the effects of Zhuyesh- igao granule (ZSG) on tumor necrosis factor-a (TNF-a), interleukin-1 (IL-1), IL-2, IL-6, and IL-8 in rats with radiation esophagitis. METHODS: Fifty Wistar rats were randomly divid- ed into five groups (10 rats in each group): con- trol (without radiation), saline-treated, and low, medium, and high-dose ISG-treated groups. Rats were given normal saline (10 mL/kg) or 1.15, 2.3, or 4.6 g/kg ZSG by intragastric administration once a day for 7 days. A rat model of radiation esophagi- tis was established by local irradiation of Co60 (490.25 cGy/min, totaling 30 Gy). The administra- tion of ZSG was continued for another 7 days and on the 7th day post-irradiation, inferior vena cavablood was collected. The serum was separated, and TNF-a, IL-1, IL-2, 11_-6, and IL-8 protein levels were determined. RESULTS: Inflammatory response factors were found in the serum of each group. However, levels in ZSG-treated groups were significantly lower than in the saline-treated group (P〈0.05). CONCLUSION: ZSG may prevent the development of radiation esophagitis, perhaps by inhibiting the generation and release of the inflammatory re- sponse factors TNF-a, IL-1, IL-2, IL-6, and IL-8.
OBJECTIVE: To investigate the effects of Zhuyeshigao granule(ZSG) on tumor necrosis factor-α(TNF-α), interleukin-1(IL-1), IL-2, IL-6, and IL-8 in rats with radiation esophagitis.METHODS: Fifty Wistar rats were randomly divided into five groups(10 rats in each group): control(without radiation), saline-treated, and low,medium, and high-dose ISG-treated groups. Rats were given normal saline(10 mL/kg) or 1.15, 2.3,or 4.6 g/kg ZSG by intragastric administration once a day for 7 days.

However, levels in ZSG-treated groups were significantly lower than inthesaline-treatedgroup(P<0.05).CONCLUSION: ZSG may prevent the development of radiation esophagitis, perhaps by inhibiting the generation and release of the inflammatory responsefactorsTNF-α,IL-1,IL-2,IL-6,andIL-8.
