ABSTRACT
Objective To investigate the effects of Qinma Formula on endogenous anti-inflammatory system in rats with chronic obstructive pulmonary disease (COPD); To discuss its mechanism of action. Methods Rat models of COPD were made by modified smoked lipopolysaccharide method. 70 healthy SPF male Wistar rats were randomly divided into normal group, model group, Western medicine control group (aminophylline group), TCM medicine control group (Liujunzi Decoction group) and Qinma Formula high-, medium-, and low-dose groups, with 10 rats in each group. Each medication group was given relevant medicine for gavage. The pathological changes of lung tissue were observed under light microscope; the alveolar lavage fluid (BALF) and venous blood were collected and the related indexes were tested; the levels of serum IL-1β, IL-6 and IL-10 were detected by ELISA. Results Compared with normal group, BALF white blood cells, neutrophils, macrophages, lymphocyte, hemoglobin and platelet count in rats of model group increased significantly (P<0.05). Compared with the model group, BALF white blood cells, neutrophils, and macrophages in rats of Qinma medium- and high-dose groups and Liujunzi Decoction group decreased significantly (P<0.05); white blood cells, hemoglobin, and platelet count in rats of Qinma medium-, high-dose groups and aminophylline group decreased significantly (P<0.05); levels of IL-1β and IL-6 in serum decreased significantly (P<0.05); level of IL-10 in serum increased significantly (P<0.05). Conclusion Qinma Formula can effectively inhibit the inflammatory response through the regulation of inflammatory response-related cytokines.
ABSTRACT
Aim Tostudytheantidepressanteffectand mechanism of Gross saponins of Tribulus terrestris. Methods Themodelofdepressionwasestablishedby unpredictable chronic mild stress(UCMS),then open filed test (OFT)and tail suspension test (TST)were used to evaluate the behavioral changes.LC-MS/MS method was employed to measure blood neurotransmit-ters.mRNA expressions of IDO,IL-10 and IL-1βwere detected by quantitative PCR method.Hippocampus protein expression was detected by Western blot.Re-sults Comparedwithcontrolgroup,modelgroup's total distance,number of standing and tail suspension fixed time increased significantly (P <0. 05 ),Neuro-transmitter level of 5-HT in the blood was significantly decreased(P<0. 05 ).mRNA expression of IDO and IL-1βwas increased in hippocampus.Protein expres-sion of IDO was significantly increased in hippocampus (P <0. 05 ).Compared with model group,the treat-ment group was significantly decreased in total distance,number of standing and tail suspension fixedtime(P<0. 05).Neurotransmitter level of 5-HT in the blood and mRNA expression of IL-10 in hippocampus were significantly increased after treatment (P <0. 05 ).mRNA and protein expression of IDO were ob-viously down-regulated in hippocampus (P <0. 05 ). Conclusions GrosssaponinsofTribulusterrestriscan obviously improve rat behavior and show antidepressanteffect,which can increase neurotransmitter level of 5-HT in the blood,down-regulate mRNA expression of IDO and IL-1β,and obviously increase protein expres-sion levels of IDO in hippocampus(P<0. 05 ).
ABSTRACT
OBJECTIVE: To observe the effect of recipes replenishing qi and activating blood on cell proliferation and apoptosis in the liver of natural aging rats. METHODS: Natural aging rats were under administration of recipes replenishing qi or activating blood for 4 months. The liver of the rats was prepared into cell suspension for determination of cell proliferation and apoptosis with PI-staining and flow cytometer. RESULTS: (1) Compared with those of the young rats, the cells in G(0)-G1 phase in the liver tissue of aging rats were increased (P 0.05). (3) The apoptosis cells in replenishing qi or activating blood group were decreased significantly (P< 0.01), and the effect of replenishing qi was better than that of activating blood (P< 0.01). CONCLUSION: (1) Cell proliferation is decreased and apoptosis is increased in the liver tissue of natural aging rats. (2) Recipes replenishing qi or activating blood can accelerate cell proliferation in the liver tissue of natural aging rats, and the effect of activating blood was slightly stronger than that of replenishing qi. (3) Recipes replenishing qi or activating blood can inhibit cell apoptosis in the liver tissue of natural aging rats, and the effect of replenishing qi was better than that of activating blood.
