目的对光活化α-三噻吩(α-T)引起的蚊幼虫脂质过氧化进行组织化学定位研究。方法用冷Schiff组织化学法,检测光活化α-T处理后的白纹伊蚊幼虫,光学显微镜下与对照组比较,观察光活化α-T引起的脂质过氧化组织定位。结果对照组组织均未着色,实验组中肠组织细胞、围食膜、马氏管刷状缘及管腔出现紫红色着色。结论光活化α-T能使白纹伊蚊幼虫的组织发生脂质过氧化,且脂质过氧化的主要组织靶标为中肠和马氏管。 Objective To investigate the histochemical localization of lipid peroxidation in mosquito larvae induced by photoactivated α-trithiophene (α-T). Methods Cold Schiff’s histochemical method was used to detect the light-activated α-T treated Aedes albopictus larvae. The light-activated α-T-induced lipid peroxidation tissue localization was observed under a light microscope compared with the control group. Results The control group did not stain the tissue, the experimental group of midgut tissue cells, peri-membrane, brush tube edge and the tube Fuchsia coloration. Conclusion Photoactivated α-T can induce lipid peroxidation in tissues of Ae. Albopictus larvae, and the major targets of lipid peroxidation are the midgut and the Markovs.
