Aim To observe the effect of DL-buthionine s ulfoximine(DL-BSO) on the radiosensitivity of rat C 6 glioma cells under the a erobic and the hypoxic condition. Methods The source of radiati on was 60Co ?-rays. The rats C 6 glioma cells were treated by radia tion alone or DL-BSO+radiation under the aerobic and the hypoxic condition. Col ony forming assay was used to measure effects of DL-BSO on the radiosensitivity . Results Radiosensitive effect of DL-BSO was time-depedent u nder the aerobic condition. After treatment with 0.1 mmol?L -1 DL-BSO fo r 2, 6, 12 hours, the radiosensitive effect was not observed, whereas an enhance ment of radiosensitivity was seen at 24 and 48 hours. An enhancement of radiosen sitivity was seen at 2～48 hours after treatment with 0.1 mmol?L -1 DL-B SO under the hypoxic condition. The radiosensitive effects related to DL-BSO co ncentration under the aerobic and the hypoxic condition. Conclusion Both under the aerobic and the hypoxic conditions DL-BSO can increase the radio sensitivity of rat C 6 glioma cells. DL-BSO increased the rat C 6 gliom a cells radiosensitivity especially under the hypoxic condition, and radiosensit ive effect of DL-BSO is time and concentration-dependent.

Objective To discuss the clinical and pathological features of herniation secondary to cerebral infarction. Method Clinical and pathologic characteristics of 50 cases died of herniation due to cerebral infarction were analysised. Results The clinical manifestations,such as consciousness disturbance,pupillary change,hemiplegia or tetraplegia were detected in all 50 cases,the average time from onset to herniation was (3.36?1.12)d,the time herniation to death was 20 h～7 d,average about (1.5?0.98)d. The large size cerebral infarctions caused by internal carotid artery,middle cerebral artery and/or vertebral artery occlusion were pathologically confirmed.hemorrhagic cerebral infarctions caused by cerebral embolism were found in 25 cases and the ischenmic infarctions caused by cerebral thrombosis in 25 caese.Site of infarction were cerebral hemisphere (31 cases), brain stem (15 cases), supratentorial and infratentorial brain (4 cases).Of the 50 cases,36 cases had hippocampal gyrus herniation,36 cases with cerebellur throat-almond herniation,18 cases with central herniation,17 cases with cingulated gyrus herniation,and 27 cases with sphenoidal crest herniation. Usually there were several herniation existing in the same patient. Among 50 cases,11cases had two kinds of herniation,10 cases with three kinds of herniation,9 cases with four kind of herniation, and 5 cases with five kinds of herniation.Conclusions Herniation secondary to cerebral infarction were mainly presented in the large size cerebral infarction caused by internal carotid artery or middle cerebral artery occlusion.the time of herniation was in early stage of disease.Most of patients were hippocampal gyrus herniation and cerebellur throat-almond herniation.Usually there were several herniation existing in the same patient.

Objective To discuss the clinical characteristics and pathological changes of basilar artery aneurysm.Methods The clinical materials and brain topography results were analyzed retrospectively in 4 patients with basilar artery aneurysm.Results The onsets of disease in all cases were acute and common manifestations were coma,positive meningeal irritation sign and ocular dyskinesis.3 cases showed hypertention,2 cases presented with hemiparalysis,all cases died of herniation.3 cases of basilar artery trunk fusiform aneurysm and 1 case of basilar artery furcation saccular aneurysm were detected in autopsy.There were aneurysm rupture,subarachnoid hemorrhage and swell,necrosis,softening,gliosis of brain tissue confirmed pathologically in all cases.Conclusion Hypertension is probably the most important cause of aneurysm rupture.Signs and symptoms of subarachnoid are the most common manifestation when basilar artery aneurysm ruptures with poor prognosis.Herniation is the main cause of death.

Objective To investigate the pharmacological actions related with therapeutic effect and indications of crude and processed semen cassiae,and to compare the differences between them.Methods Serum contents of ALT and AST were determined in acute liver injury mice induced by CCl4,the intestinal propulsion of Evans blue was measured in normal mice and in constipation mice,and stool properties,defecation latency and defecate amounts in constipation mice were also investigated.Results Both crude and processed semen cassiae showed obvious liver-protective effects,and decreased the contents of ALT and AST in serum,but processed semen cassiae was better than crude in protecting liver.Both of them increased the intestinal propulsion in normal and constipation mice,improved the stool properties,shortened the defecate latency and increased the defecate amounts in constipation mice.Conclusion Both crude and processed semen cassiae have the effects of protecting liver,lubricating bowel and promoting defecation.The processed is superior to the crude in liver protection and enzyme decrease,and they have similar effect in lubricating bowel and promoting defecation.
