Effects of chemotherapy with angiotensin II-induced hypertension on transplanted intracerebral rat gliomas / 中国病理生理杂志

ABSTRACT

AIM: To observe morphological changes in transplanted intracerebral rat gliomas and rat survival time with gliomas under chemotherapy with angiotensin II-induced hypertension. METHODS: C6 glioma cells were cultured, and the effects of carmustine, nimodipine or/and teniposide on gliomas cells was observed. In addition, the brain tumor model was established in Wistar rats by stereotaxic inoculation of C6 glioma cells. The tumor-bearing rats were treated with carmustine, nimodipine lisplatin or/and teniposide during angiotensin II-induced hypertension, the pathological changes in gliomas was also examined. RESULTS: In vitro experiments showed chemotherapy resulted in morphologic changes in glioma cells, including cell enlargement, degeneration. In vivo experiments, the survival time of tumor-bearing rats was longer, the voume of gliomas was smaller in chemotherapy with hypertension group than those in chemotherapy alone, and pathological examination showed necrosis in the gliomas. CONCLUSION: Chemotherapy with angiotensin II-induced hypertension has a better inhibitory effect on rat intracerebral gliomas than chemotherapy alone.
