摘要

In order to study the mechanism of immunopotentiator, the quantity of T lymphocyte was observed. Total 240 1-day chikens were divided into 3 groups randomly: one contrast group and two groups being drunk immunopotentiator according to the concentration 10 mL·L~(-1) and 5 mL·L~(-1) lasting for 48 d. The number of T lymphocyte in blood was measured by E-rosette when the chikens were at 12-, 24-, 36-, and 48-day. The results showed that the percent of T lymphocyte in the trial group was obviously higher than that of the contrast, and the 10 mL·L~(-1) group was higher than that of the 5 mL·L~(-1) group; the quantity distribution of T lymphocyte in intestinal mucosa lymphoid tissue of 14-day, 21-day chiken was surveyed hi the contrast group and the 10 mL·L~(-1) group with the method of routine histology-slices and ANAE, the results showed that the quantity of T lymphocyte in the 10 mL·L~(-1) group was significantly higher than that of the contrast, which indicated that immunopotentiator increased markedly the quantity of T lymphocyte, and the 10 mL·L~(-1) group was higher than that of the 5 mL ·L~(-1) group.
