    [Objective]To observe the protective effects of volatile oil,water decoction containing oil,water decoction without oil extractives from the compatibility of Herba schizonepetae and Radix saposhnikoviae on lipopolysaccharide-induced acute lung injury in mice,and reveal the anti-inflammatory effects and material base of this medicine pair. [Methods] The ALI model was prepared by injecting 5 mg /kg of lipopolysaccharide(LPS) into the enterocoelia of mice. Mice in dexamethasone group were injected once into enterocoelia(5 mg /kg),while in the rest groups gavage administration on mice was continued for 5 days and once each day,and modeling was done 30 min after the last time of administration(except the blank group). After LPS was injected for 6 h,blood was taken from mice and the serum was isolated,bronchoalveolar lavage fluid(BALF) was collected and the lung tissue was drawn out. The following items were measured: white blood cell count and differential count; total protein content in mice BALF; lung index,lung wet /dry(W /D) weight ratio; myeloperoxidase(MPO) activity and malonaldehyde(MDA) content of lung tissue; the level of serum interlukin 6(IL-6),interlukin 10(IL-10) and tumor necrosis factor α(TNF-α). [Results]Via the use of volatile oil(45. 19 μL/kg) and water decoction containing oil(6. 67 g/kg,containing 20 μL oil) from the compatibility of Herba schizonepetae and Radix saposhnikoviae,whole blood white blood cell(WBC) and lymphocyte(LY) counts in ALI mice were significantly reduced,lung index,lung W /D weight ratio,lung tissue MPO activity and MDA content were decreased,and the increase of serum IL-10 and TNF-α content was restrained; via the water decoction without oil(6. 67 g /kg),whole blood WBC and LY counts,lung W /D ratio and lung tissue MDA content were significantly reduced. Serum IL-6 level was also significantly decreased by volatile oil. [Conclusions]Volatile oil and water decoction containing oil extracted from the compatibility of Herba schizonepetae and Radix saposhnikoviae can exert good oppositional effects on the lung tissue inflammatory lesion of ALI mice. It manifests anti-inflammatory effects,and the action mechanism is related to inhibiting the release of inflammatory cytokines and antioxidation. Volatile oil can be regarded as one of the important material bases for it to exert anti-inflammatory effects.

    Jingfeng YANG;Yanyun REN;Qiufang ZHAO;Tiancai ZHAO;Yonggang WANG;Xiangsen WANG;

    [Objective]Observe effects of Didang Qigui decoction on crystalline lens,lens epithelial cells and the level of HSP70in rats with streptozotocin induced diabetic cataract. [Methods]10 SD rats were randomly selected as the blank control group,and the rest of rats were injected 60 mg /kg of streptozotocin(STZ) into the enterocoelia at one time to reproduce diabetic rats models. 55 of the model animals were selected and randomly divided into model group,diamicron group,Didang Qigui decoction group,Didang Qigui decoction high dose group,Didang Qigui decoction and diamicron group,and corresponding interference was given to each group respectively. Turbidity of the lens was examined under the slit lamp respectively at 2,4,6,8 week; after 8 weeks,morphologic changes of crystalline lens were observed under the microscope,and the expressions of HSP70in lens epithelial cells(LEC) were detected. [Results] Crystalline lens of rats in the blank control group were always transparent and complete. Those of rats in the model group were gradually changed until becoming complete turbid. The rest of treatment groups with turbidity degree of rats' lens from heavy to light were Didang Qigui decoction high dose group,Didang Qigui decoction group,diamicron group,and Didang Qigui decoction and diamicron group. Forms of HE staining lens epithelial cells were also changed. If rats in the blank control group were taken as standards,expressions of HSP70in LEC of crystalline lens in the model group gradually rose. In the treatment groups,the rate of HSP70positive expression of rats in the Didang Qigui decoction high dose group was higher than that rate in diamicron group,idang Qigui decoction group,and Didang Qigui decoction and diamicron group. The discrepancy was very obvious( P < 0. 05).[Conclusions]By reducing blood glucose,gathering of sugar metabolites and osmotic pressure in crystalline lens,Didang Qigui decoction can effectively protect lens injury in experimental diabetic rats and inhibit the occurrence and development of cataract in diabetic rats,so it exerts certain preventive and therapeutic effects on early diabetic cataract in rats.
