Effects of Wei Chang An pill on enzyme activity and levels of vasoactive peptide and substance P in the small intestine of rats with compound diarrhea

Objective

To investigate the regulatory effects of Wei Chang An Pill (WCAP) on enzyme activity and gastrointestinal hormones in the small intestine of rats with compound diarrhea.

Methods

Forty Wistar rats were randomly divided into a control, diarrhea model, and WCAP high, medium, and low dose groups. The control group was not treated, and the model group was administered intragastric distilled water. The WCAP groups were given WCAP suspension, 80, 60 or 40 mg · kg⁻¹ · d⁻¹, for 4 days. Stool properties were observed. After the experiment, thymus and spleen indices were measured, and the activities of lactate dehydrogenase (LDH), malate dehydrogenase (MDH), and disaccharidase (lactase) in the small intestinal mucous membrane, and levels of substance P (SP) and vasoactive peptide (VIP) in the colon were determined.

Results

Compared with the control group, thymus and spleen indices were significantly decreased, LDH, MDH, and disaccharidase activity in the small intestine was decreased, and SP and VIP levels in the colon were significantly increased in the diarrhea model group. Compared with the model group, thymus and spleen indices were significantly increased, and LDH, MDH, and disaccharidase activity in the small intestine and SP and VIP levels in the colon were significantly decreased in the WCAP medium dose group.

Conclusion

The diarrhea model rats exhibited pathological changes including atrophy of the thymus and spleen, decreased enzyme activity in the small intestine, and gastrointestinal hormone disturbance. WCAP can increase the activity of intestinal digestive enzymes and regulate gastrointestinal hormones, thereby relieving diarrhea.     

Metabonomic analysis of the therapeutic effect of Zhibai Dihuang Pill in treatment of streptozotocin-induced diabetic nephropathy

Ethnopharmacological relevance

Zhibai Dihuang Pill (ZDP) is one of ancient traditional Chinese medicines (TCMs), which is usually used for the treatment of kidney deficiency for thousands of years in China.

Aim of the study

Traditional Chinese medicines (TCMs) usually operate in vivo through multi-components, multi-ways and multi-targets. However, the molecular mechanisms of TCMs remain unclear. In the present work, nuclear magnetic resonance (NMR)-based metabonomic analysis was used to evaluate the therapeutic effect of Zhibai Dihuang Pill (ZDP) on diabetic nephropathy (DN) rats induced by streptozotocin and to address the underlying molecular mechanism.

Materials and methods

Male rats were divided into three groups: control, DN and ZDP-treated DN (ZDP-DN), respectively. Based on ¹H NMR spectra of sera, urine and kidney extracts from the rats, principle component analysis (PCA) was performed to identify different metabolic profiles. Kidney portions and serum and urine samples were also subjected to histopathological or biochemical examination.

Results

PCA scores plots demonstrate that the cluster of DN rats is separated from that of control rats, while some of ZDP-DN rats are located close to control rats, indicating that metabolic profiles of these ZDP-DN rats are restored toward those of control rats. Our results illustrate that ZDP treatment could lower the levels of lipids and 3-hydrobutyrate, and raise the level of lactate in sera of DN rats. Moreover, ZDP treatment could also reduce the levels of glucose, 3-hydrobutyrate and lactate, enhance the level of betaine in kidney tissues.

Conclusion

Our study indicates that ZDP treatment can ameliorate DN symptoms by intervening in some dominating metabolic pathways, such as inhibiting glucose and lipid metabolism, enhancing methylamine metabolism. Our work may be of benefit to both evaluation of the therapeutic effect of TCM and elucidation of the underlying molecular mechanism.
