The results showed that with increasing age, the thymus weight increased, and the thymus index rose first and then decreased. The addition of G. pentaphyllum increased the thymus weight and thymus index to a certain extent. With the increase of the age, the thymic cortex-medullar ratio decreased, and at 120 d, the cortex-medullar ratio of the fed group was significantly greater than that of the non-added group（P<0.05）. The number of thymus bodies in the non-feeding group and the feeding group increased before 56 and 90 d, respectively, and then decreased in a wave pattern. At 28, 90, and 120 d, the number of thymus bodies in the fed group was significantly more than that in the non-fed group（P<0.05）. The thymus body area of the non-feeding group and the feeding group increased before 120 d, and then decreased. The day-to-day differences of the non-feeding group and the feeding group were not significant. Adding G. pentaphyllum powder in the feed can prolong the thymus maturation time, delay the thymus degradation, and improve the thymus function.

The results show that the high, medium and low dose groups of Coptis chinensis extract have protective effects on mice with abdominal infection caused by S. aureus, E. coli, P. aeruginosa, P. vulgaris, and K. pneumoniae, can significantly reduce the content of TNF-α and IL-6 in mouse serum. Coptis chinensis extract has a certain antibacterial effect, and its mechanism is related to TNF-α and IL-6. Reference | Related Articles | Metrics
