[Hygienic regulation of static electric field generated by devices with electron-ray tube].

When detecting and hygienically assessing the static electric field generated by the devices with a half-tone storage tube it is necessary to take account of the impact of a number of characteristics of field intensity ranging on the obtained results. Taking into consideration the above characteristics during the research permits to lower error in the derived values and approximate them to the characteristics affecting the organisms of those using devices with a half-tone storage tube.

[Antimutagenic and antiteratogenic properties of dimexide (DMSO)].

The influence of dimexide (dimethylsulphoxide, DMSO) on the manifestation of teratogenic and embryolethal properties and mutagenic effect of pyrimethamine (antimalarial drug) and 6-mercaptopurine (antitumoral compound) has been examined. Under the conditions of preliminary action of dimexide the embryolethal and teratogenic activity of the drugs studied reduced on the 13th day of rat embryos; the level of cytogenic effect of these compounds on rat males bone marrow cells also reduced.
