玉米幼芽提取物对家蚕抗氧化损伤作用的影响

Pathology Observation of Protection Effect of Oxidation Damage Resistance on Bombyx mori by Feeding Extracts of Maize Plumule

研究了两种玉米幼芽提取物对家蚕抵抗氧化损伤过程中相应病理学变化的影响,以及对细胞的保护作用机制。结果表明,用玉米幼芽提取液添食的各组家蚕与损伤对照组相比,血液中的T-SOD活力显著升高,细胞病变程度减轻,胞内质膜附近有大量钙离子分布。初步认为,两种玉米幼芽提取物在家蚕抵抗氧化损伤的过程中具有良好的保护细胞结构,增强细胞抗性的作用。

Experiments were carried out to study the effect of two extracts of maize plumule on resistance to oxidation damage, pathological change on Bombyx mori, and on protection of cells. The results showed that activities of T-SOD enhanced significantly in each test group administrated with the extracts of maize plumule compared with the control. The cell damages were also alleviated by different extent in each test group, and large amounts of calcium ion were distributed around plasma membrane, So the two kinds of extracts of maize plumule can help skin cells of silkworms resist oxidation damage, protect the cell structure.
