[Epizootiology of foot rot in sheep].

Investigations were carried out on the outbreak and spread of foot rot in sheep as well as on the ways of its restriction and eradication. It was found that the disease had been introduced with the import of breeding animals, its further spread being associated with the activity of the Breeding Centers for pedigree animals. The diseased animals have been 25 per cent, on an average, for the whole country, and the economic losses, as expressed in production parameters, have amounted to: produce of animal origin--20 per cent; culling of animals--15 per cent; mortality--1 per cent. Best in the group treatment of the affected animals prove: the dipping in a 5--10 per cent solution of formalin or a 20 per cent solution of copper sulfate, combined with the respective surgical and orthopedic handling and the disinfection of premises. The individual parenteral treatment and the local application of antibiotics and chemotherapeutics have proved suitable and successful in the cases of moderate spread of the disease. The eradication of foot rot can be achieved only via the planned and complex application of pertinent measures.

[Products of the interaction of ethazole with mustard oils].

Synthesized were nonsymmetrical N1N1--replaced products of thiocarbamide containing residual alkyl- and arylsinapic oils and the sulfonamide ethasole, in order to study their pharmacologic activity. The synthesis was performed through heating the components up to the point of weak boiling in an ethanol medium. The obtained nine new N1N1--thiocarbamide products were identified in terms of their melting point and sulfur analysis. Tentative microbiologic testing showed that the newly obtained compounds produce bacteriostatic and bactericidal effects.

[Our experience with the 131-I treatment of thyrotoxicosis].

The authors analyze 100 patients, with thyrotoxicosis, 84 females and 16 males, treated with 131J. The enlargement of the thyroid gland was II degree in 57 per cent and III degree in 34 per cent, and I and II - for the rest of the cases. In 77 per cent the body weight of the patients was below the norm. Exophthalmos was observed in 48 per cent. As a result of treatment an involution of a series of pathological symptoms developed- tachycardia, ECG changes, exophthalmos, degree enlargement of the thyroid gland, blood indicies, weight, capacity for work. Euthyroidism was established in 86 per cent, partial remission in 12 per cent and hypothroidism - in 2 per cent, when followed up during an interval of 2-13 years. No genetic or blastomogenic changes were observed. Observations is recommended in the later periods after the treatment.

[Complex-forming factors in the dilution of bull sperm for deep freezing].

Micro- and ultramicroelectrophoresis on Cellogel were employed to study the formation of complexes of bull's semen and the constituents of Nagaze-Niva's extender in all possible combinations. It was found that a new glycoprotein complex is formed in mixing the semen with yolk. This complex was found to bind 82 +/- 1.5 per cent of all proteins in the sample. The addition of lactose to the yolk-diluted semen was shown to lead to the dispersion of this complex into 4--5 subunits. The cation fraction of the semen plasma and glycerin were established to take no part in the complex formation. Discussed are the problems associated with the dispersion effect of lactose and the higher (twice to three times) survival rate of semen trated with extenders containing saccharides.
