In 1956, adenovirus from human adenoid cell culture was designated Adenovirus. At present there are about 100 kinds of serotypes, 51 kinds of serotypes of can present human adenovirus infection serotype 7 existing in subspecies B most often cause severe pneumonia and other diseases highly relative to mortality. Following by enterovirus and respiratory cell fusion virus, Adenovirus is the third position of domestic infant respiratory tract infection.In the past, there was a significant increase in the levels of interleukin-6, interleukin-8, and tumor necrosis factor alpha (TNF-α) in the serum when the human was infected with adenovirus. It is important to examine the levels of cytokines in the pathogensis after infected virus.Milk thistle is a medicinal food possessing anti-inflammatory effect. In this experiment, the A549 cell line infected with adenovirus was incubated with milk thistle water extract. The cytopathic effect (CPE), cell count and cytokine assay were conducted to investigate whether the extract had a delayed effect.The results showed that milk thistle water extract can slow down the cytopathic effect and cell death rate. Although inflammatory cytokines did not reveal direct relationship to the previous results, the other cytokines may be possibly involved and needed to be further investigated.腺病毒細胞病變效應介白素-6介白素-8腫瘤壞死因子-αAdenovirusytopathic effectinterleukin-6interleukin- 8tumor necrosis factor alphathesis
