In group E, which had just experienced 30-minute cold storage without rewarm ischemia, hepatic function could well be recovered in a short time during reperfusion. On the contrary, in group F、G and H, which had experienced rewarm ischemia for 15, 30 and 60 minutes respectively following 30-minute cold storage, hepatic function suffered the more severe damage with the more prolonged rewarm ischemia during reperfusion.

在对供肝复温缺血-再灌注损伤的研究中发现，供肝于再灌注期间，仅低温保存30分钟而无复温缺血的E组供肝功能于短时间内即可得到很好的恢复，但低温保存30分钟后又分别经历15、30、60分钟复温缺血的F、G、H三组供肝，其肝脏功能却遭到了明显的损伤，且复温缺血时间越长者，损伤程度越重。

Tea polyphenols not only has the above aspects of the pharmacological effects, but also has effects of anti- saprodontia, eliminating bad breath, antibacterial, anti-virus, and cosmetic field, it is also enhance the body's comprehensive immunization ability to a certain extent, The American Medical Foundation President J.H.
