RESUMEN
BACKGROUND: Eggembryosin is characterized by tonifying kidney and vital essence, invigorating qi and spleen, replenishing and activating blood, beautifying and nourishing face, and improving constitution of whole organism.OBJECTIVE: To observe the influence of eggembryosin on aging index,quantity of hemocytes and quality of immune organs of animal models, and analyze its effect on cosmetology, anti-senility and immunoloregulation.DESIGN: Randomized controlled observation.SETTING: Department of Pharmacology, Xinxiang Medical College.MATERIALS: The experiment was carried out in the Department of Pharmacology of Xinxiang Medical College between April 1998 and September 2002. A total of 80 Kunming mice of both sexes were selected in this study.METHODS: ① Effect of eggembryosin on activity of superoxide dismutase (SOD) in serum, content of malondialdehyde (MDA), lipofuscin and hydroxyproline respectively in serum, liver and tendon of tail of aging mice: Thirty mice were divided into 3 groups according to randomly lined table, including eggembryosin group, D-galactose model group and normal control group with 10 in each group. The former two groups were injected with D-galactose to copy aging models, and eggembryosin group were perfused with eggembryosin to measure activity of SOD in serum, content of MDA, lipofuscin (aging index) and hydroxyproline (elasric index of skin) respectively in serum, liver and tendon of tail. ② Effect of eggembryosin on mass of immune organs of mice with low immunological function: Thirty mice were selected and divided as the same way mentioned above. Mice in eggembryosin group were perfused with eggembryosin. In addition, those in eggembryosin group and cyclophosphamide (CAP) group were peritoneally injected with CAP to copy immunosuppression models and calculate index of thymus (spleen) (mg/g) = weight of thymus (spleen)/body. ③ Effect of eggembryosin on quantities of erythrocytes and hemoglobin of mice with blood deficiency: Twenty mice were divided into 2 groups according to randomly lined table, including eggembryosin group and normal control group with 10 in each group. Values of erythrocytes and hemoglobins of mice were measured before administration. Models in types of blood-deficiency blood-loss were copied with tail xsanguinations, and then, mice were perfused with eggembryosin and saline, respectively. Blood of mice were collected from their tails to measure values of erythrocytes and hemoglobin.MAIN OUTCOME MEASURES: Activity of superoxide dismutase (SOD) in serum, content of malondialdehyde (MDA), lipofuscin and hydroxyproline respectively in serum, liver and tendon of tail of aging mice, index of thymus, and spleen, contents of blood erythrocytes and hemoglobins.RESULTS: A total of 80 mice were involved in the final analysis without any loss. ① Activity of SOD in serum and contents of hydroxyproline in tendon of tail of mice in eggembryosin group were significantly higher than those of mice in D-galactose model group (P ＜ 0.01); content of MDA in serum and content of lipofuscin in liver of mice in eggembryosin group were significantly lower than those of mice in D-galactose model group (P＜ 0.01). ② Indexes of thymus and spleen of mice in eggembryosin group were higher than those of mice in CAP group (P ＜ 0.05-0.01). ③ Increasing values of blood erythrocytes and hemoglobin of mice in eggembryosin group were significantly higher than those of mice in normal control group (P ＜ 0.01).CONCLUSION: Eggembryosin taken orally can improveanti-oxidation of organism and elasticity of skin, increase quality of immune organs damaged by CAP and immunological function, and nourish the blood.
RESUMEN
BACKGROUND:Huperzine A is a reversible choline enzyme(CHE) inhibitor initially developed in China,which has favorable therapeutic effectiveness in benign memory dysfunction,and could significantly promote the learning process and memory reappearance in rodent animals. OBJECTIVE:To comprehend the impacts of Huperzine A on the enhancement of learning, memory and behavior in platform and maze experiments in D Galoctose(Gal) induced senile mouse model. DESIGN:A randomized and controlled trial. SETTING:Institute of Pharmaceuticals of Xinxiang Medical College. MATERIALS:Study was performed in the Laboratory of Physiology and the Institute of Pharmaceuticals of Xinxiang Medical College from January to December in 2002.A total of 100 healthy Kunming mice were selected for platform and electric maze experiments with 50 mice in each experiment.Huperzine A tablet was obtained from Henan Zhulin Zhongsheng Pharmaceutical Company Limited(batch number:031001).D Gal is the product of Shanghai No.2 Reagent Factory. MAIN OUTCOME MEASURES:The latency in the safe area on the platform and the times of electric shock occurred within 5 minutes were observed in mice in platform experiment;the times of the mice mistakenly escaping to the right electric attacking area were observed in mice in electric maze experiment. CONCLUSION:Huperzine A can effectively improve the learning and memory ability of D Gal induced senile mice, and there is dose effect relationship within certain range.
