Objective To study the anti-inflammatory and analgesic effects of Jingtongning Capsule. Methods Models of acute inflammatory reactions of croton oil-induced mouse ear edema and carrageenan-induced rat raw swelling and chronic inflammatory reaction of cotton ball-induced mouse granuloma in abdominal cavity were performed to study the anti-inflammatory effects of Jingtongning Capsule. Model of acetic acid-induced writhing in mice was used to study the analgesic effect of Jingtongning Capsule. Results Jingtongning Capsule significantly suppressed croton oil-induced mouse ear edema and carrageenan-induce rat paw swelling. Cotton ball-induced mouse granuloma in abdominal cavity was also markedly reduced by Jingtongning Capsule. The writhing times of mice induced by acetic acid were decreased by Jingtongning Capsule. Conclusions Jingtongning Capsule has obvious anti-inflammatory effect on acute and chronic inflammatory reactions. The pain reactions induced by chemical stimulus was significantly relieved by Jingtongning Capsule.

Objective The aim of the study is to investigate whether the progressive incremental exercise can induce the change in bone maximum force.Methods One hundred and seventy healthy SD rats,aged 3 months,were used as samples after adaptive exercise for one week,and then they were divided to a basic control group(C_0),8 control groups and 8 exercise groups according to the training duration(2W,4W,6W,8W,9W,11W,13W and 15W).Based on Bedford and our pre-study.the longest training duration of the rats was 15 weeks.The maximum force(F) of femoral bone and the 2nd lumbar vertebrae(L_2)were tested by three-point bending test and compressive test separately.Results It was shown that there was no pronounced difference in F of femoral bone between con trol groups and exercise groups.But significant differences in F of L_2 were found between the control groups and exercise groups(P<0.001).Conclusions Changes in different degree were found in the F of femoral bone and L_2 during the process of growth.The differential effects of incremental exercise on F were caused by the difference in training intensities and in the bone types.

Objective To evaluate the value of CT and MRIin diagnosis of littoral cell angioma(LCA) of spleen.Methods CT and MRI findings the data of 6 patients with LCA were rospectively analyzed,and all patients were proved LCA of spleen by pathology.Then enhanced CT (n =4 cases) and MRI (n =2 cases) were performed.The imaging performance of LCA was observed,and its imaging features was summarized.Results None of patients showed obvious signs and symptoms of hypersplenism,4 cases were with splenomegaly.5 patients had a single lesion,only one had few lesions.There were not any calcification or envelopement of all the lesions.On CT,all lesions demonstrated distinct borders.The enhanced scan for low-density nodules demonstrated slow progressive enhancement.On MRI,all the LAC had well circumscribed borders,and demonstrated T1 · hypointense and T2-equal,hyperintense signals,and progressive enhancement on the post contrast images.Conclusion CT and MRI imaging of littoral cell angioma of spleen have special imaging characteristics,those particular findings is helpful in the diagnosis.

AIM: To study the acute toxicity of bioactive compounds from paecilomyces tenuipes (BCPT) and the effect of BCPT on lipid peroxidation of brain in chronic stress model (CMS) of depression in rats. METHODS: The depression animal model was induced by chronic unforeseeable stress (CUS). The maximally tolerated dose (MTD) was used to detect the acute toxicity of BCPT. UV spectrophotometer analysis technique was used to detect the activity of SOD, GSH-PX and CAT, and content of MDA and NO in rat's brain. RESULTS: The MTD of BCPT was 9 g?kg -1 . BCPT could obviously enhance the activities of SOD, GSH-PX and CAT, and also significantly inhibit the increase of MDA and NO content in brain in CMS rats. CONCLUSION: BCPT has little toxicity and produces an antidespressant-like effect in antioxidation in CMS rats.

Aim Exploration of the effects of bioactive compound from paecilomyces tenuipes (BCPT) on the behavior, ultrastructure of hippocampus, and expressions of BDNF and Bax of cerebral cortex in CUS rats. Methods The depression model rat was induced by chronic unpredictable stress(CUS). The Open field test was used to observe the behavior of CUS rats. The expressions of BDNF and Bax of cerebral cortex were studied using immunohistochemical method, and average optical density of cortical neuron was calculated by image analysis. Morphology of hippocampus was observed by transmission electron microscope. Results Compared with model group, BCPT could obviously increase the activity of ambulation and rearing and the number of positive neuron of BDNF, decrease the number of positive neuron of Bax, and effectively prevent pathological damage induced by chronic unpredictable stress. Conclusion BCPT may exhibit the effects of antidepression, up-regulate the expression of BDNF, down-regulate the expression of Bax, and improve of the ultrastructure of hippocampus.
