摘要：<正> In present study, the developmental patterns of somatostatin (SS) gene expression in gastric tissue were compared between Erhualian and Large White pigs. A semi-quantitative RT-PCR was applied to determine the levels of SS mRNA. The results indicated that: (1) The gastric SS mRNA expression was high at birth, followed by a significant decrease (P<0. 05) at 3 days of age in both breeds of pigs; (2) From 3 to 30 days of age, the expression of SS mRNA in gastric tissue exhibited remarkable up-regulation in both breeds, after which a strain difference in the developmental pattern was observed. In Erhualian pigs, SS mRNA expression reached a peak at 90 days of age, declined thereafter towards 180 days of age. In Large White pigs, however, the expression of SS mRNA remained constant from 30 days of age onwards; (3) In general, Erhualian pigs expressed higher levels of SS mRNA in gastric tissue compared with Large White pigs at the same age. The strain difference was significant from birth to 90 days of age, b
