西洋参保值加工要领

由于西洋参根含有大量的淀粉和糖分,极易被害虫蛀蚀和微生物侵染腐烂,参根采收后经过加工干燥可防止虫蛀和变质。另外,西洋参的主要成分人参皂甙,     

人参皂甙Rb1对禽流感疫苗的免疫佐剂作用

大量研究表明,人参皂甙是一种很好的免疫增强剂,它具有增强单核巨噬细胞系统功能,促进特异性抗体的生成和淋巴细胞转化,促进某些淋巴因子的分泌,对天然杀伤细胞干扰素白介素2调节网起正调节作用,并能保护受病毒侵袭的组织细胞。人参皂甙作为免疫增强剂的研究有过相关的报道,但多停留在人参总皂甙的研究。研究用人参皂甙Rb1单体作佐剂,将人参皂甙Rb1与禽流感油乳剂灭活疫苗配合使用,来研究人参皂甙Rb1对鸡的免疫增强作用,同时也为人参皂甙在禽流感防制上的应用提供依据。1材料与方法1.1试剂人参皂甙Rb1,大连生生绿谷生物有限公司生产,批号2…     

糖萜素对雏鸡免疫器官影响的研究

糖萜素主要由寡糖、三萜皂甙和有机酸组成(三萜皂甙≥30%,总糖≥30%)。糖萜素中的有效成分性能稳定,使用安全,与其他饲料添加剂均无配合禁忌。糖萜素的主要作用是激发、增强机体免疫力和抗病力,维护肠道微生态平衡,抑制有害菌的繁殖,抗应激和抗氧化作用。试验的目的是研究糖萜素对雏鸡免疫器官发育的影响。1材料与方法1.1试验动物及分组将1日龄海兰褐公雏480只(由吉林农业科技学院鸡场提供)随机分为4组,每组4个重复,每个重复30只鸡。常规饲养,自由采食、饮水。预饲3d后开始试验。1.2试验药品糖萜素,由浙江大学研制,宁波联合生物技术有限公司…     

Effects of Momordica grosvenori Saponins on Type 2 Diabetes Rats Induced by High-sucrose/High-fat Diet and Streptozotocin

The purpose of the experiment was to study the effect of Momordica grosvenori saponins on improving the effect of high-sucrose/high-fat diet combined with streptozotocin induced type 2 diabetes in rats.The type 2 diabetes rat model was established with a high-sucrose and high-fat diet combined with streptozotocin.Successfully modeled rats were given the total saponins of Momordica grosvenori (100,200,400 mg/kg) or metformin (268 mg/kg) by gavage,once a day for 4 weeks.Recording the "three more and one less"index (24 h internal urine output,water intake and feed intake,body weight);Detecting of biochemical indicators,analysis of fasting blood glucose (FBG),serum total cholesterol (TC),triglycerides (TG),low-density lipoprotein cholesterol (LDL-C),high-density lipoprotein cholesterol (HDL-C),insulin (INS),catalase (CAT),superoxide dismutase (SOD),malondialdehyde (MDA),alanine aminotransferase (AST),aspartate aminotransferase (ALT),blood urea nitrogen (BUN) and creatinine (Cr) levels.Hematoxylin-eosin staining (HE) was used to observe the pathological changes of the pancreas.Compared with the model group,the feed intake,water intake,urine output,blood indicators FBG,INS,MDA,TC,TG,BUN and Cr levels,AST and ALT activities were significantly or extremely significantly decreased in the total saponins of Momordica grosvenori each dose group and metformin group (P<0.05;P<0.01),while CAT,SOD activities and HDL-C level were significantly or extremely significantly increased (P<0.05;P<0.01).In pancreatic tissue,the number of pancreatic cells was increased significantly,and the pathological damage of the pancreas was significantly reduced. Momordica grosvenori saponins and metformin had obvious effects on improving glucose metabolism disorders,and at the same time could significantly reduce insulin resistance,enhance the body’s ability to resist oxidative stress and improve liver and kidney functions.
