"By thinning this mucous [layer], we increased the susceptibility to infection," Finlay said at the meeting.

“通过稀释这种分泌粘液层，我们加快了感染的敏感性”，芬利在会议上说。

When the researchers dissected these now susceptible mice, they discovered that the mucous layer that typically lines the gut was only half as thick as in protected mice.

当研究人员解剖这些现存的易感染的小鼠时，他们发现其肠道典型的线性分泌粘液层的厚度仅为受保护小鼠的一半。

Thee stomach has a relatively large epithelial surface, but because it has a thick mucous layer and the time that the drug remains there is usually relatively short, absorption is limited.

胃具有相对大的上皮表面，但由于它有较厚的粘液层，而且药物在胃内停留的时间相对较短，吸收也较少。
