Extensive lesions involving the posterior quadrant of the cerebral hemisphere (temporal, parietal, and occipital lobes) induce intractable epilepsy. These patients are potential candidates for surgical treatmenttu. Maintenance of isolated nerve tissue activity after surgery plays a crucial role in the neuroprotective effects of neurosurgery treatment. Disconnection surgery of the posterior quadrant is used to completely isolate nerve fibers, while blood supply at the isolated lobes is maintained. Subsequently, cavities caused by cystic or necrotic nerve tissues should be reduced as much as possible, 展开更多

O6-methylguanine DNA methyltransferase (O6-AT) is an enzyme for the repair of the promutagenic structure, O6-aIkylguanine, from alkylated DNA, therefore low activity of O6-AT is involved in the predisposition of tissues to some nitrosamines and the development of cancer. The levels of O6-AT in livers of ducks from Qidong (Qd), a high incidence area of liver cancer, and from Qingpu(Qp), a relatively low incidence area were determined in this study. The results showed that the activity of O6-AT was higher in Qp than in Qd. It suggested that some nitrosamine in Qd might be one of factors responsible for the higher incidence of ducks liver cancer, because these ducks were more sensitive to nitrosa-mine. 展开更多

The activity of DNA topoisomerase Ⅱ prepared from either normal or tumor tissues were compared. It was found that the unknotting activity of the enzyme in malignant tumor cells was higher than that in normal cells. We selected some antitumor drugs including Chinese traditional medicine, and observed their effects on the unknotting activity of topoisomerase Ⅱ. The results showed that inhibition of the unknotting activity of the enzyme required very low concentrations of drugs, but much higher concentrations were required for other tested. Some antitumor drugs had no effect on the enzyme were also proved. It is interesting that carrageenan, an antiviral drug, strongly blocked the unknotting activity although its antitumor activity has not been reported. 展开更多

The present experimental technique is used to study the image, crystal phase, pore structure and microstructure of artificial silica fume, and the experimental results show that artificial silica fume is a non-crystalline and porous matter with a high specific surface area and the high activity of volcanic ash. Therefore, it is a type of ideal material which can replace silica fume. (Author abstract) 5 Refs. 展开更多
