樂胃飲對胃癌前病變大鼠模型自噬基因Beclin1的影響
[Abstract]:Aim: to observe the effect of Lue Wei Yin on autophagy and its related gene Beclin1 in gastric mucosa of (PLGC) rats with gastric precancerous lesion. Methods: sixty male Wistar rats were divided into normal group, model group, retinol group, low, middle and high dosage group of lewei Yin, which were perfused with 2% sodium salicylate. The PLGC model was induced by combined factors such as hunger and satiety and free drinking of 1-methyl-3-nitro-1-nitrosoguanidine (MNNG) solution. After 28 days of administration, the autophagy of rat gastric mucosal cells was observed by transmission electron microscope, and the expression of Beclin1 m RNA was detected by RT-PCR. Results: compared with the model group, the expression of Beclin1 m RNA in gastric mucosa of each dose group was significantly higher than that in the model group (P0. 05 and P0. 01). Autophagy was observed under electron microscope. Conclusion: Lue Wei Yin may decrease the possibility of carcinogenesis by increasing the expression of Beclin1 and enhancing PLGC gastric mucosal autophagy.
