ABSTRACT
Objective To study effects ofXiangsha Liujunzi Decoction (XSLJZ) on gastric emptying function, pepsin activity and expression of HIF-1α gene and protein of gastric mucosa in chronic atrophic gastritis (CAG) of rats with deficiency of spleen and stomach.Methods Rats were randomly divided into normal group and model group. The models of CAG rats with deficiency of spleen and stomach type were induced by synthetic methods. After the modeling, models rats were divided into model group, positive control group and XSLJZ high-, medium-, and low-dose groups. Normal group and model group were given 10 mL/kg distilled water every day for gavage; XSLJZ high-, medium-, and low-dose groups were given 24, 12, and 6 g/kg XSLJZ Decoction for gavage; positive control group was given 0.30 g/kg Vatacoenayme for gavage, for successive 120 d. Gastric emptying function and pepsin activity were detected, and HIF-1α gene and protein expression in gastric mucosa were detected by RT-qPCR and IHC. Results Compared with the normal group, the gastric emptying function and pepsin activity in the model group were much lower (P<0.01); expressions of HIF-1α gene and protein in gastric tissues was much higher (P<0.01). Compared with model group, XSLJZ could increase the gastric emptying function and pepsin activity significantly (P<0.05), and decrease expressions of HIF-1α gene and protein (P<0.05).Conclusion XSLJZ has functions of improving the gastric emptying function, promoting pepsin activity, and reducing expressions of HIF-1α gene and protein.
ABSTRACT
Objective To observe effects of Kangshuai Yizhi Capsule on ATP in brain tissue and IL-6, TNF-α in serum of aging model rats, and explore the protective effects of the capsule on brain tissue.Methods Totally 72 rats were randomly divided into a normal group and a model group. The subacutely aging model rats were made by injectingD-gal, then aging rats were numbered and grouped by random number table into the model group, Kangshuai Yizhi high-dose group, Kangshuai Yizhi Capsule low-dose group and Naofukang group. All dose groups were received gavage by giving corresponding doses, while normal group and model group were given the same amount of saline everyday. After treated for 60 days, the activity of Na+-K+-ATP and Ca2+-Mg2+-ATP in brain tissue, and IL-6, TNF-α in serum were detected.Results Compared with normal group, Na+-K+-ATP and Ca2+-Mg2+-ATP were less active (P<0.05), but levels of IL-6 and TNF-α in model group were significantly higher, with statistical significance (P<0.05). Compared with model group, after treated with Kangshuai Yizhi Capsule, Na+-K+-ATP and Ca2+-Mg2+-ATP were more active, and IL-6 and TNF-α levels were down-regulated significantly in dose groups, with statistical significance (P<0.05). Meanwhile, Kangshuai Yizhi Capsule high-dose group showed the most obvious effect among dose groups.ConclusionKangshuai Yizhi Capsule has effects of enhancing activity of ATP in brain tissue and reducing level of proinflammatory factors.
ABSTRACT
Objective To explore the effects of Kangshuaiyizhi capsule on ChAT/AchE and NE, DA and 5-HT levels in the brain tissue of aging model rats, and explore its effect of protecting cerebral function. Methods Totally 72 rats were randomly divided into normal group and model group. The subacutely aging model rats were made by injecting D-gal (0.125 g/kg) into abdominal cavity continually, then aging rats were divided by random number table into model group, Naofukang group and Kangshuaiyizhi high-, low-dose group. After intervented with correspongding drugs for 60 days, activity of ChAT and AchE, cerebral cortex NE, DA, and 5-HT levels were detected. Results Activity of AchE was much higher (P<0.05), but level of ChAT, NE, DA and 5-HT in model group were significantly downregulated compared with normal group (P<0.05). After treated with Kangshuaiyizhi capsule, activity of AchE was downregulated, ChAT, NE, DA and 5-HT levels were significantly upregulated (P <0.01, P <0.05). Conclusion Kangshuaiyizhi capsule can regulate cholinergic and monoamine neurotransmitter levels in the brain tissue of aging model rats, and play a very important role in protecting cerebral function.
