A human heteroploid cell line of malignant origin (J111) was infected with Mouse Moloney Sarcoma Virus. [MSV-M(MLV)]. The replication of the virus was demonstrated by different methods. After a few passages of infected cultures, the transforming component of MSV-M(MLV) disappeared from the supernatant fluids and cells. The non transforming helper component continued to be produced. The relatively low amount of helper virus released by the cells suggests a control of its replication in the J111 cellular system. 相似文献

Sports activities in the vocational education centres are viewed as an indispensable rehabilitation measure. Its contents and organizational structure however is to a large extent left to the individual centres. Implementation of effective sports is endangered by the lack of homogeneity in the young trainee population as regards type and severity of the disability, age, maturity. After setting out the present situation and the function of sports in a vocational education centre for physically disabled young people, a school course system is presented that, by achieving a relatively homogenous composition of the sports groups, enables sport-oriented instruction to be realized. In this course system, the young people are allocated to the various courses through sport selection and counselling, based on the criteria of inclination and suitability. The range of sports offered also includes sports for the very severely handicapped, which are described briefly. 相似文献

A series of compounds was synthesized, these compounds were tested for Hela-S3cells in vitro for radiosensitizing activity. Five of them are 2,2′- (arylimino)-diethyl-sodium thio-sulfate and two of them are phenylalanine derivatives. Most of them showed various degrees of ra-diosensitizing activity. Among them, SER of L07 was 1.89 at 3 mmol, and had low cytotoxicity toHela-S3 cells;ID50 was 18.8 mmol. The relationship between radiosensitizing effects and chemicalstructure was discussed. It offers a base for further exploration of selectively hypoxic cell radiosens-itizers. 相似文献
