The effect of green tea on the intestinal mucosa was not studied previously, so we examined the effects of green tea on the intestinal mucosa of fasting rats in a controlled experimental setting.
Two sets of experiments were performed. In the recovery set, rats were fasted for 3 d, after which they were allowed free access to water, black tea, green tea, or vitamin E for 7 d. On day 8, the animals were killed, and small bowels were removed for histologic examination.
In the recovery set, fasting for 3 d caused shortening of villi, atrophy, and fragmentation of mucosal villous architecture, with a significant (P _ 0.0001) reduction in the length and surface area of the villi. Ingestion of green tea and, to a lesser extent, vitamin E for 7 d helped in the recovery of villi to normal. In the pretreatment set, drinking green tea, black tea, or vitamin E for 14 d before fasting protected intestinal mucosa from damage.

兩套實驗被進行。在確定的恢復過程中， 老鼠適合3 d齋戒， 在此之後，他們被允許免費水，紅茶，綠茶或者7 d的維生素E 的入口。 在天8，動物殺死，小腸適合histologic 檢查除去。
在確定，有一顯著的(P適合絨毛，萎縮，和mucosal的碎裂具長柔毛的建築的引起縮短的3 d戒齋的恢復內 _ 0.0001) 在絨毛的長度和表面面積方面的削減。 綠茶的吸收和，在較小程度上，7 d的維生素E 促進對正常的絨毛的恢復。 在確定的pretreatment裡，正在為14 d喝綠茶，紅茶或者維生素E 時，在齋戒之前保護腸的mucosa免受的損害。Source(s): 我
