背景:鸡胚胎具有补肾填精、益气健脾、补血养血、美容养颜、提高机体整体体质的作用。目的:观察鸡胚胎素对动物模型某些衰老指标、血细胞数量及免疫器官质量的影响,分析其抗衰老、美容及免疫调节作用。设计:随机对照观察。单位:新乡医学院药物研究室。材料:实验于1998-04/2002-09在新乡医学院药物研究室完成,选择昆明小鼠80只,雌雄各半。方法:①鸡胚胎素对衰老小鼠血清超氧化物歧化酶活性、丙二醛含量、肝脏脂褐素含量及尾腱中羟脯氨酸含量的影响:取30只小鼠,按随机排列表法分为3组,即鸡胚胎素组、D-半乳糖模型组和正常对照组,每组10只。前两组注射D-半乳糖复制衰老模型,鸡胚胎素组小鼠灌服鸡胚胎素,测定各组小鼠血清超氧化物歧化酶活性、丙二醛含量、肝脏脂褐素含量(衰老指标)及尾腱中羟脯氨酸含量(皮肤弹性指标)。②鸡胚胎素对免疫功能低下小鼠免疫器官质量的影响:取30只小鼠,分组方法同上。鸡胚胎素组小鼠灌服鸡胚胎素,鸡胚胎素组、环磷酰胺模型组小鼠腹腔注射环磷酰胺复制免疫抑制模型,计算胸腺(脾)指数(mg/g)=胸腺(脾)质量/体质量。③鸡胚胎素对血虚小鼠红细胞及血红蛋白数量的影响:取20只小鼠,按随机排列表法分为2组,即鸡胚胎素组和正常对照组,每组10只。测各组小鼠给药前血红细胞和血红蛋白值,应用尾部放血法复制失血性血虚模型后,分别灌胃鸡胚胎素和生理盐水,尾部采血测红细胞和血红蛋白值。主要观察指标:小鼠血清超氧化物歧化酶活性、丙二醛含量、肝脏脂褐素含量、尾腱中羟脯氨酸含量、胸腺指数、脾指数、血红细胞及血红蛋白含量。结果:80只小鼠全部进入结果分析,无脱失。①鸡胚胎素组小鼠的血清超氧化物歧化酶活性及尾腱中羟脯氨酸含量均显著高于D-半乳糖模型组(P<0.01);鸡胚胎素组小鼠的血清丙二醛含量及肝脏脂褐素含量均显著低于D-半乳糖模型组(P<0.01)。②鸡胚胎素组小鼠的胸腺、脾指数均显著高于环磷酰胺模型组(P<0.05～0.01)。③鸡胚胎素组小鼠的血红细胞和血红蛋白增值均显著高于正常对照组(P<0.01)。结论:口服鸡胚胎素具有提高机体抗氧化能力的作用,能显著增加皮肤弹性,对于环磷酰胺造成的免疫器官质量及其免疫功能下降具有明显的改善作用,并且具有较好的补血作用。

Effect of eggembryosin on cosmetology, anti-senility and immunoloregulation

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.
