目的

探讨苦杏仁对老年慢传输型便秘大鼠结肠组织干细胞因子(stem cell factor, SCF)、酪氨酸激酶受体(c-kit)、间隙连接蛋白43(recombinant connexin 43, Cx43)表达的影响和作用。

方法

随机将60只老年SD大鼠分为苦杏仁实验组、模型对照组、空白对照组,每组20只。通过喂饲复方苯乙哌啶建立便秘模型。苦杏仁实验组大鼠给予苦杏仁煎剂(0.17 g·kg-1·d-1),空白对照组和模型对照组大鼠给予等量0.9%氯化钠溶液。10 d后处死大鼠测算肠道推进率,提取结肠组织,采用Western blot和RT-PCR技术检测大鼠结肠组织SCF、c-kit、Cx43蛋白及mRNA的表达水平。多组间比较采用方差分析,进一步两两比较采用LSD-t检验。

结果

3组大鼠肠道推进率的差异明显(F=17.515,P<0.01),模型对照组优于空白对照组、苦杏仁实验组优于模型对照组(P<0.01)。3组大鼠SCF、c-kit、Cx43蛋白及mRNA的表达差异均有统计学意义(F=39.565、186.912、35.760,94.879、71.543、99.986;P<0.01);与空白对照组比较,模型对照组大鼠结肠组织SCF、c-kit、Cx43蛋白及mRNA的表达水平均明显降低(P<0.01);与模型对照组比较,苦杏仁实验组大鼠结肠组织SCF、c-kit、Cx43蛋白及mRNA的表达水平均明显上调(P<0.01)。

结论

慢传输型便秘的发病与SCF、c-kit、Cx43的变化密切相关,苦杏仁可能是通过修复部分SCF/c-kit信号通路、促进Cx43的表达而发挥改善肠道功能的作用。

Objective

To study the effects of bitter almond on the expression of stem cell factor (SCF), c-kit, recombinant connexin 43 (Cx43) in old slow transit constipation rats.

Methods

60 SD rats were divided into blank control group, model control group, bitter almond experimental group randomly ,with 20 rats in each group. Compoud phenanthroline was used to build the model of slow transit constipation. The bitter almond experimental group was gavaged with bitter almond apozem (0.17 g·kg-1·d-1), the other groups were gavaged with equal saline. Rats were sacrificed after 10 days, the intestinal propulsion rate were measured and specimens were taken. Western blot and RT-PCR techniques were used to measure the expression of protein and mRNA of stem cell factor (SCF), c-kit, and recombinant connexin 43 (Cx43) in rat colon tissue. Analysis of variance was used for comparison between groups, and LSD-t test was used for further pairwise comparison.

Results

The intestinal propulsion rate of the three groups was significantly different (F=17.515, P < 0.01), the model control group was better than the blank control group (P < 0.01), and the bitter almond experiment group was better than the model control group (P < 0.01). The expression of SCF, c-kit, connexin 43 protein and mRNA were significantly different among the three groups (F=39.565, 186.912, 35.760, 94.879, 71.543, 99.986, P < 0.01). Compared with the blank control group, the expression of SCF, c-kit, Cx43 protein and mRNA in the model control group was significantly reduced (P < 0.01); compared with the model control group, the expression of SCF, c-kit, Cx43 protein and mRNA in the bitter almond experimental group was significantly up-regulated (P < 0.01).

Conclusion

The onset of slow transit constipation is closely related to the changes of SCF, C-Kit and Cx43. Bitter almond may improve intestinal function by repairing part of the SCF/c-kit signaling pathway and promoting the expression of Cx43.
