[Effects of salt-softener composition on the contents of toxic elements in processed cheeses]. / Vliianie sostava solei-plavitelei na soderzhanie toksichnykh élementov v lomtevykh plavlenykh syrakh.

Contents of toxic elements in salt-smelters using in Russia at manufacturing of processed cheeses and in ready cheeses were studied. The levels of arsenic and lead were 4.4 and 1.2 times higher than allowed levels. Sodium three polyphosphate was found as the resource of toxic element incorporation in processed cheeses. The control of contents of toxic elements in salts are needed at manufacturing of processed cheeses.

[Study of possibilities of accumulation of S. aureus enterotoxins during the production and storage of processed cheeses]. / Issledovanie vozmozhnosti nakopleniia énterotoksinov S. aureus pri vyrabotke i khranenii plavlenykh syrov.

The conditions of survive of enterogenic staphylococci in models of production and storage of processed cheeses were studied. The possibilities of S.aureus propagation and accumulation of great doses of thermo-stable enterotoxin were observed in cheese mass before processing. It was established probability of detection of staphylococcus enterotoxins in processed cheeses, produced from the poor quality raw materials.

[The diagnostic value of transvaginal pelvic phlebography in gynecologic oncology]. / Diagnosticheskaia tsennost' chrezvlagalishchnoi tazovoi flebografii v onkoginekologii.

The paper discusses an original procedure of transvaginal visceral phlebography of the pelvis for examination of patients with tumors of the corpus and cervix uteri and those in whom intravaginal phlebography is contraindicated. The procedure proved simple and highly informative. Contraindications are not numerous and it can be carried out on outpatient basis.

[Mechanism of a decrease of inducibility of tyrosine aminotransferase by carcinogenic aminoazo dyes. Absence of direct influence of o-aminoazotoluene on the enzyme molecules]. / K voprosu o mekhanizme snizheniia indutsibel'nosti tirozinaminotransferazy kantserogennymi aminoazokrasiteliami. Otsutstvie priamogo vliianiia o-aminoazotoluola na ferment.

The effect of o-aminoazotoluene (OAT) on the activity of tyrosine aminotransferase (TAT) from mouse liver cytosol under its incubation in the presence of the systems providing for the metabolic activation of the cancerogen (liver microsomes and NADPH2) and dephosphorylation of TAT molecules (light mitochondria and ATP) was studied. It was shown that OAT has neither direct nor indirect (via the phsophorylation--dephosphorylation systems) effect on the activity of TAT. It was concluded that the decrease of TAT induction by hydrocortisone in vivo resulting from injection of OAT to the mice is not due to the direct influence of the cancerogen on the enzyme molecules.
