Objective To explore possible physiological and biochemical mechanisms of Lagenidium giganteum infection in killing mosquito larvae. Methods The content of lipid and the activities of esterase and lipase between the normal and infected mosquito larvae were observed with histochemical method. The results were photomicrographed and analysed by image analysis using computer. Results In 24 hrs after infection, the content of lipid in the infected Culex quinquefasciatus larvae was lower while the activities of esterase and lipase in the larvae were higher than the control. In 48 hrs and 78 hrs after infection, the content of lipid in the infected larvae of C. quinquefasciatus and Ae. albopictus were significantly lower while the activities of esterase and lipase were significantly higher than those of control. Conclusion The content of lipid in the mosquito larvae decreased while the activities of esterase and lipase increased after the infection of Lagenidium giganteum . The disorder of lipid metabolism might be part of the killing mechanisms to C. quinquefasciatus and Ae. albopictus larvae.

4cm) or involved the urethra、 vagina、 clitoris or anus. Pathologic grouping was 25 squamous carcinomas 3 adenocarcinomas and 2 undifferentiated carcinomas. Radiotherapy was given by angled radiation with wedge block. Dose was 65 to 70 Gy/6-7W. RESULTS Thirty patients completed their inductive chemotherapy within 30 days for 86 courses. The response rate was 86. 7% (26/30). CR was 30. 16%. 18 of 30 patients were followed-up for over 5 years. Five years survival rate was 72.2 (13/18). Major acute complications were vuvitis (23%). Late adverse effects were 1 patient with ure-throstenotic uroschesis, 1 patient with pathologic transcervical fracture. None of patients had radiation rectitis and cystitis. CONCLUSION Inductive chemotherapy consisting of modified VBP regimen was active in reducing the vulvar tumor volume. Radiotherapy used angled radiation with wedged block to treat advance vulvar cancer was fa-ciliated. Chemoradiotherapy was found to be an effective treatment for locally advanced vulvar carcinoma, with acceptable morbidity even in an elderly population. The technique allowed maintenance of normal anatomical and physiologic function that would have been compromised by primary surgical approach. It yielded survival rates comparable to those achieved with ultraradical surgery in younger patients. Life quality was improved significant-ly.
