蝇蛆营养活性粉保健功能的评价

以不同剂量蝇蛆营养活性粉喂饲昆明种小鼠,测定其免疫调节、抗疲劳、抗辐射及护肝作用,结果表明：小鼠喂饲蝇蛆营养活性粉后,细胞免疫功能、体液免疫功能和单核巨噬细胞吞噬功能都显著增强,同时,蝇蛆营养活性粉还具有抗疲劳、抗辐射和对四氯化碳性肝损伤具有保护作用;果蝇生存试验表明：蝇蛆营养活性粉可延长果蝇的平均寿命及最长寿命,在以小鼠为试验动物进行生化指标测试后,发现蝇蛆营养活性粉可明显减少血清及１０％肝匀浆过氧化脂质（ＬＰＯ）含量和显著升高血清超氧化歧化酶（ＳＯＤ）活性,说明蝇蛆营养活性粉有延缓衰老的作用。     

蝇蛆几丁糖保健功能的评价

以化学方法制备的蝇蛆脱乙酰几丁糖,按不同剂量喂饲试验动物雄性大鼠,检测其对试验动物的降血脂作用,结果表明：蝇蛆几丁糖能显著降低大鼠血清总胆固醇（ＴＣ）和甘油三酯（ＴＧ）水平。以蝇明几丁糖不同剂量喂饲昆明小鼠,检测其对小鼠抗突变和促进小肠运动作用的影响,结果表明：蝇蛆几丁糖可明显降低致突物环磷酰胺对小鼠骨髓嗜多染红细胞的微核发生率和丝裂霉素Ｃ对小鼠睾丸染色体畸变发生率,对ＴＡ９８的抗突变试验结果为阳     

VISUAL RESPONSES IN THE EYE OF THE DRAGON FLY

Responses to illumination recorded from cells in the eye of the dragonfly are similar to responses of cells in the eye of Limulus and are affected in the same manner by currents through the cell membrane. It appears probable that visual responses are brought about by the same processes in the two species.     

THYMECTOMY: PROLONGATION OF IMMUNOLOGICAL TOLERANCE IN THE ADULT MOUSE

The loss of acquired immunological tolerance of mice to bovine gamma globulin depended on the presence of the thymus. Mice were repeatedly injected with bovine gamma-globulin from birth until the age of 5 to 10 weeks and then thymectomized or sham operated. After 130 to 160 days without antigen, an accelerated (immune) disappearance of I(125) bovine gamma-globulin could be uniformly induced in controls while thymectomized mice remained tolerant. Adult thymectomized mice made tolerant by a single injection of bovine gamma-globulin lost tolerance more slowly than sham-operated controls.

一类新型植物生长延缓剂的作用机理及其应用

含有降冰片烯二氮杂环丁烯、三唑、嘧啶、吡啶和咪唑类结构的一类新型植物生长延缓剂,其共同的特征是在分子内杂环中的 sp~2杂化 N 上具有一对孤对电子。这对孤对电子作为第六配体结合到细胞色素 P-450内血红素铁上,代替了催化反应中所需的氧,导致某些依赖细胞色素P-450的单氧酶失活,并因此影响与 GA,ABA 和甾醇等有关的代谢途径,进而调节植物的生长和发育过程。因此,这类植物生长延缓剂在农林和园艺等方面具有广泛的应用前景。
