Abstract:
The differences in dryness between raw Aurantii Fructus Immaturus(AFI) and bran-fried products were investigated based on a slow-transit constipation(STC) model. Seventy healthy SPF-grade rats were randomly divided into a blank group(K), a positive drug group(Y), a model group(M), low-and high-dose raw AFI groups(SD and SG), and low-and high-dose bran-fried AFI groups(FD and FG). During the experiment, it was found that compared with the K group, the groups with drug treatment had little effect on the daily body weight of the STC rats. The first defecation time of black stool in the M group was significantly higher than that in the K group, and the 24-hour fecal output significantly decreased starting from the 13th day, indicating successful modeling. The SG group showed a significant increase in the first defecation time, fecal water content, urine output, and water intake than other groups with drug treatment. The FG group had the highest fecal output than other groups with drug treatment. The FD group had the highest salivary secretion than other groups with drug treatment. The levels of cAMP/cGMP, VIP, 5-HT, AQP1, and AQP5 were measured in each group with drug treatment, and the expression of c-Kit and SCF mRNA in gastric antrum tissue and AQP3 mRNA in the kidney and colon were detected by RT-PCR. The results showed that the SD and SG groups had a more significant impact on AQP1, AQP5, and other water channel indexes in STC rats than the FD and FG groups. The FD and FG groups had a more significant impact on c-Kit, SCF, VIP, 5-HT, and other gastrointestinal motility indicators than the SD and SG groups. This study, through in vitro biological observations, immunological detection, and gene expression analysis, found that raw AFI had strong dryness property, while bran-fried AFI could alleviate its dryness property.
