In four calves given Haemonchus contortus larvae, the serum pepsinogen concentration rose quickly to reach a mean of 3.5 iu tyrosine on day 14 after infection. The mean concentration dropped to 1.8 iu tyrosine by day 23 and remained around 2.0 iu tyrosine until an anthelmintic was given on day 57, when concentrations returned to preinfection values.
在给四只小牛接种捻转血矛线虫幼虫后，血清胃蛋白酶原浓度迅速上升，在感染后第14天达到平均3.5国际单位酪氨酸。到第23天，平均浓度降至1.8国际单位酪氨酸，并在第57天给予驱虫药之前一直维持在约2.0国际单位酪氨酸，给药后浓度恢复到感染前水平。
