The therapeutic mechanism of YYL was probed by observing the degree of the damage of rats' colon Mucosa and assessing serum contents of IgA, IgG, IgM and IL-ⅱ.

Toronto Pearson International Airport ( YYZ) seems an unlikely source of Virginia-crossing flights, but Canada's largest airport contributes more flights over Virginia than New York's JFK and LaGuardia airports combined.

多伦多皮尔逊国际机场乍看起来一点也不像弗吉尼亚被飞越次数的杰出贡献者，但其实这个加拿大最大的机场飞往弗吉尼亚的航班比纽约的约翰•肯尼迪国际机场和拉瓜迪亚机场的航班加在一起还要多。

Her performance didn't rate high in the competition.
