Effects of Shengjiang (Rhizoma Zingiberis Recens)-Huangqin (Radix Scutellariae) Herbal Pair at Diffe-rent Composition Ratios on Energy Metabolism Enzymes, Gastrointestinal Motility and Brain-gut Peptides in Rats with Stomach Cold Syndrome
) herbal pair at different composition ratios in the treatment of stomach cold syndrome, and to explore its potential mechanism.
Methods
2
SD rats were randomly divided into blank group (n=12) and model group (n=60). The rat model of stomach cold syndrome was established by the method of gavage with pure water at 0 ℃ plus cold water bath and sodium hydroxide stimulation for 18 days. Fifty successfully modeled rats were randomly divided into model group, Shengjiang group, Shengjiang-Huangqin (S-H) 1∶1, 5∶3, and 2∶1 group, with 10 rats in each group. The blank group and the model group were gavaged with 10 mL/kg of normal saline, while Shengjiang group was gavaged with 3.6 g/kg of Shengjiang decoction, and S-H 1∶1, 5∶3 and 2∶1 groups were gavaged with 7.2, 9.6 and 10.8 g/kg of corresponding S-H decoction, respectively. All groups were gavaged once a day for 7 consecutive days. The general condition of rats was observed. The contents of energy metabolizing enzymes glucokinase (GCK), pyruvate dehydrogenase (PDH), isocitrate dehydrogenase (ICD), Na
+
-K
+
-ATPase (Na
+
-K
+
-ATP) and adipose-triglyceride lipase (ATGL) in liver tissue of rats in each group were detected. The pathological morphology of gastric tissue was observed, and the gastric emptying rate and small intestinal propulsion were calculated. The contents of motilin (MTL), 5-hydroxytryptamine (5-HT), gastrin (GAS), somatostatin (SS) and vasoactive intestinal peptide (VIP) in gastric tissue were determined.
Results
2
Compared to those in the blank group, the gastric mucosa of the rats in the model group was incomplete, and the mucosal tissue was necrotic and exfoliated, with disorderly arranged glands and a large number of infiltrated inflammatory cells. Compared to those in the model group, local mucosal necrosis and shedding, as well as inflammatory cell infiltration were seen in the S-H 1∶1 group. The gastric mucosa epithelial structure was complete, and the glands were neatly arranged in other medicinal groups, with no obvious inflammatory cell infiltration. Compared to those in the blank group, the contents of GCK, PDH, ICD and Na
+
-K
+
-ATP in liver tissue, gastric emptying rate and small intestinal propulsiion, as well as the contents of 5-HT, MTL and GAS were significantly reduced in the model group, while the contents of SS and VIP significantly increased
(P
<0.01). Compared to those in the model group, the contents of GCK, PDH, ICD and Na
+
-K
+
-ATP in liver tissue, gastric emptying rate and small intestinal propulsion, as well as the contents of 5-HT, MTL and GAS in stomach tissue significantly increased, while the contents of SS and VIP significantly decreased in Shengjiang group, S-H 5∶3 and 2∶1 groups; the contents of PDH and ICD in liver tissue significantly increased, while the contents of SS and VIP in stomach tissue significantly decreased in the S-H 1∶1 group (
P
<0.05
or
P
<0.01). Compared to those in the Shengjiang group, the contents of GCK, PDH, ICD, and Na
+
-K
+
-ATP in liver tissue, gastric emptying rate, small intestinal propulsion, and the contents of 5-HT, MTL and GAS in stomach tissue significantly increased, while the VIP content significantly decreased in S-H 5∶3 group; the contents of GCK, PDH, and Na
+
-K
+
-ATP in liver tissue, and small intestinal propulsion significantly increased in S-H 2∶1 group (
P
<0.01
or
P
<0.01). S-H 2∶1 group had higher GCK, PDH, ICD contents in liver tissue and VIP content in stomach tissue, as well as lower gastric emptying rate and contents of 5-HT, MTL and GAS in stomach tissue than S-H 5∶3 group (
P
<0.05
or
P
<0.01).
Conclusion
2
S-H decoction at different composition ratios all have effects on stomach cold syndrome by regulating the activity of energy metabolism enzyme and the content of brain-gut peptide. The effect is varied, and S-H at the ratio of 5∶3 may be the best.
