Objective To explore the effects of citicoline injection into Zusanli point (ST36) on learning and memory function of rats after traumatic brain injury (TBI). Methods The model was induced with the improved Feeney method. The rats were randomly divided into 5 groups: sham-operation group, control group, acupuncture point saline injection group, intraperitoneal drug injection group and acupuncture point drug injection group with 8 rats in each group. The rats in the acupuncture point drug or saline injection group were treated with acupuncture injection of citicoline or saline daily. The rats in the intraperitoneal drug injection group and control group were treated with intraperitoneal injection of citicoline or saline daily. The treatment continued for 14 d. The learning and memory function was evaluated with the Morris water maze test and passive avoidance test. Results Acupuncture point injection of citicoline can significantly shorten the escape latent period of TBI rats in Morris water tests and extend the latent period of learning and memory of TBI rats (P<0.05). Conclusion Acupuncture point injection is effective on the recovery of learning and memory function of rats after TBI.

Objective:To study the immunoisolation effects of alginate-polylysine-alginate(APA)-microcapsules in vito.Methods:To observe changes of cellular immune and tectology of sheeps after hollow microcapsules, Bovine Chromaffin Cells(BCCs) and APA Microencapsulated BCCs(APA-BCCs) transplanted to the spinal subarachnoid space.Results:The blood lymphocyte numbers of each group didn't change; APA-microcapsule could prevent blood CD4 +T lymphocyte , CD4 +/CD8 + and CSF lymphocyte from increasing caused by BCCs transplantation; APA microencapsulation could reduce histological reactions in transplantation area and prolong the survival of the transplant.Conclusion:APA microcapsules possess the immunoisolation effects and can efficiently prevent immunoreactions.

BACKGROUND: The effective chemical constituents and the precise action mechanism of Cassia obtusifolia L. seed to rats with hypercholesterolemia are not clear. OBJECTIVE: To investigate effects of anthraquinones from Cassia obtusifolia L. on hypolipidemic activity and endogenous cholesterol biosynthesis in rats with experimental hyperlipoidemia, and to explore the effective compound and the mechanism of Cassia obtusifolia L. seed on hypolipidemic action. DESIGN, TIME AND SETTING: The randomized controlled animal experiment was performed from September 2003 to May 2004. All rats were raised and tested at the College of Life Sciences, South China Normal University. Blood sample was collected from the tail vein at the Institute of Biotechnology to detect blood lipid, survival rate, and to culture cells. MATERIALS: Forty-five male Sprague Dawley (SD) rats were used to establish animal models of hypedipoidemia by intragastrically with fat emulsion. Cassia obtusifolia L. seed was purchased from Guangzhou Dispensary, China, and further identified by South China Plant Institute. Anthraquinones were extracted from Cassia obtusifolia L. by the Institute of Biotechnology of South China Normal University. METHODS: Forty-five male SD rats were randomly divided into three groups (n=15): a control group, 80 mg/kg and 20 mg/kg anthraquinones groups. Rat models in each group were given fat emulsion in the morning and afternoon 2 days after model induction, once in morning. Rat modes were treated with corresponding doses of drugs in the two experimental groups. Rat models were administrated with the same volume of saline in the control group, once a day, for 20 days. MAIN OUTCOME MEASURES: Effect of anthraquinones on endogenous cholesterin in Chinese hamster oocytes was measured by amphotericin B cell models. The levels of serum total cholesterol, triglyceride, low-density iipoprotein-cholesterol (LDL-C) and high-density lipoprotein-cholesterol (HDL-C) were detected by enzyme endpoint method. Survival rate of Chinese hamster oocytes (A570) was tested by methyl thiazolyi tetrazolium (MTT) with spectrophotometric determination. RESULTS: Anthraquinones significantly reduced total cholesterol, triglyceride, LDL-C levels and increased HDL-C levels in hyperlipidemic rats in a dose-dependant pattern. Anthraquinones elevated the survival rate of Chinese hamster oocytes. CONCLUSION: Anthraquinones can decrease blood lipid levels. Inhibition of cholesterol synthesis of anthraquinones may be one of the underlying mechanism involved in decreasing blood lipid.

Objective In order to offer a noninvasive and objective examination method for assessing the clinical diagnosis and eurative criterion of concussion patients, the patients color three - dimensional transcranial doppler( 3D - TCD) characteristic at deferent phases, parameter and clincal manifestation were studied Method Parameter of Median Cerebral Artery(MCA), Base Artery(BA), the average peak forwand velocity of cerebral blood flow, train figure were tested by 3D - TCD within 24 hours, 3 - 6 days and at the end of treatment, respectively. The results were compared with clinical diagnoses and curative criterion. Result Among 135 patients who had clinically diagnosed concussion, agreeable diagnoses 101 cases, basically agreeable diagnooses 12 cases, disagreeable diagnosis 22 cases(16. 2%) .At the end of treatment, according to clinical determination 96 cases(71.1%) were cured, 39 cases(28.9%) were improved. Wave train character, figure and diagnoses prameter of cerebral spasm caused by concussion were suggested Conclusion To be one of the diagnostic bases and curative criterion, 3D- TC D technology is performable. Meanwhile, it is a new testing objective technique for assessing curative and determining prognosis.
