The regularity of immediate early gene (IEG, c-fos) mRNA expression was studied to investigate the pathogenesis of perinatal ischemic-hypoxia. We set up an animal model of perinatal ischemic-hypoxia with Wistar rat by ligating the uterine vessel of one pregnant horn. The other horn was not ligated and the fetuses were used as controls. Pups were delivered by cesarean section at the end of the ischemic-hypoxic (IH) insult and then the brain tissues were collected in differrent times. In situ hybridation...

The regularity of immediate early gene (IEG, c-fos) mRNA expression was studied to investigate the pathogenesis of perinatal ischemic-hypoxia. We set up an animal model of perinatal ischemic-hypoxia with Wistar rat by ligating the uterine vessel of one pregnant horn. The other horn was not ligated and the fetuses were used as controls. Pups were delivered by cesarean section at the end of the ischemic-hypoxic (IH) insult and then the brain tissues were collected in differrent times. In situ hybridation was used to detect the expression of c-fos mRNA. our results showed that the expression of c-fos mRNA was shown immediately (0 minute) in hippocampus and cerebral cortex, increased as the time went on. peaked at 1 hour the high expression lasted 2 hours and subsided gradually after 4 hours. However. more intensive c-fos mRNA expression was found at 24 hours and then the expression disapeared at 72 hours. only a trace of hybrid signal could be found at 1 hour in hippocampus in the control group. These results indicated that immediate early gene c-fos could be induced by perinatal ischemic-hypoxia. The expression of c-fos mRNA might induce the transcription of its target genes, especially, some "killer genes". which would be harmful to the brain tissue.

为探讨围产期缺血缺氧脑损伤的发病机制,本实验对c-fos在脑缺血缺氧后的表达变化规律进行了研究。通过结扎Wistar孕鼠一侧子宫角血管的方法(未结扎侧子宫角作为对照),建立围产期缺血缺氧脑损伤动物模型。采用原位杂交方法观察了剖宫产后存活不同时间的大鼠大脑c-fosmRNA的表达,结果发现,缺血后即刻,大脑皮层和海马即出现c-fosmRNA的表达。随时间延长,表达量逐渐增加,至1h时,杂交信号最强,维持到2、4h后逐渐减弱。但到24h时.c-fosmRNA又出现第二次高表达,以后又逐渐减低,48h表达极微,3d后各组都未检出其表达。对照组仅在生后1h海马有较少量c-fosRNA的表达。结果表明,宫内缺血缺氧引起了即刻早期基因c-fosmRNA的表达增强,且具有一定规律性。c-fos的改变可能会引起其后续靶基因尤其是一些与细胞死亡相关基因的转录,从而引起脑组织的病理损害。

AIM: To investigate the expression of bak (bcl 2 homologous antagonist/killer) gene protein in human adrenal pheochromocytoma and the significance of bak expression in tumorigenesis. METHODS: Twenty three paraffin embedded specimens of adrenal pheochromocytoma (18 cases of benign pheochromocytoma and 5 cases of malignant pheochromocytoma) and 10 cases of normal human adrenal gland were investigated by immunohistochemistry (SABC method) for bak gene protein expression. RESULTS: Bak was negative...

AIM: To investigate the expression of bak (bcl 2 homologous antagonist/killer) gene protein in human adrenal pheochromocytoma and the significance of bak expression in tumorigenesis. METHODS: Twenty three paraffin embedded specimens of adrenal pheochromocytoma (18 cases of benign pheochromocytoma and 5 cases of malignant pheochromocytoma) and 10 cases of normal human adrenal gland were investigated by immunohistochemistry (SABC method) for bak gene protein expression. RESULTS: Bak was negative in normal adrenal medulla tissues (10 of 10 cases),but positive in pheochromocytoma (18 of 23 cases, 78%), 89% for benign pheochromocytoma and 40% for malignant. The incidence of Bak positive tumors in benign pheochromocytoma was significantly higher than that in malignant tumors ( P <0.05). CONCLUSION: Though to different degrees, bak is involved in the regulation of apoptosis in benign and malignant pheochrocytoma, which may be a potential means to differentiate the malignant pheochrocytomas from the benign ones.

目的: 探讨凋亡相关基因bak 在人肾上腺嗜铬细胞瘤中的表达及其对肿瘤发生的意义. 方法: 应用免疫组织化学的SABC方法,和兔抗人Bak 多克隆抗体,对23例肾上腺嗜铬细胞瘤(其中良性18例,恶性5例)和10例正常肾上腺组织进行了检测. 结果: Bak 在正常肾上腺髓质中不表达,而在良恶性嗜铬细胞瘤中表达,阳性率分别为89% 和40% . 在良性肿瘤中Bak 表达显著强于恶性肿瘤. 结论: Bak 不同程度地参与了良恶性嗜铬细胞瘤中的凋亡调控,对良恶性嗜铬细胞瘤鉴别诊断的意义有待深入研究.

Spore killer gene (SK k), a genetically abnormal variant in Fusarium section Liseola, was found in this study. More than 95 percent of asci produced by sexual cross of strains YM9 7 from corn and MH50 from cotton contained 4 spores. Typical 8 spore asci (98%) were got when the cultures from the F 1 progenies backcrossed to strain MH50. It was confirmed that strain MH50 contains a spore killer gene (SK k).
