Intrinsic nerves of the pectoralis major and minor in man

In the human intraorganic nerves of the thoracic muscles amyelin fibers make 62% and myelin ones--38%. In transversal sections ultrastructure of the myelin and amyelin fibers varying in their diameters has been studied. In the myelin and amyelin fibers the amount of various organells is not equal: in the amyelin fibers the arrangement density of microtubules is greater than that of neurofilaments, there is a reverse dependence between the amount of the microtubules and the neurofilaments on the one hand, and the fibrilar diameter, on the other hand. In the myelin fibers with the increasing diameter, the amount of the neurofilaments increases, while that of the microtubules decreases.     

The action of an enzymatically stable Leu-enkephalin analog on the prostanoid content in the myocardium under stress- and adrenaline-induced damage

The protective action of enzymatically stable analogue of Leu-enkephalin (D-ala-2-leu5-arg6), injected intraperitoneally, in the course of stress- and epinephrine induced myocardial damage was demonstrated in animal (129 white rats) experiments. Two effect of enkephalin were sufficient for the cardiac protection: enkephalin-stimulated prostacyclin biosynthesis and simultaneous inhibition of thromboxane production.     

Detection of the complex of chromatin DNase-tRNA by gel filtration

By gel filtration on Sephadex G-100, the formation of the complex of chromatin DNase-tRNA has been detected. The complex is reactivated after RNase treatment. The molecular weight of the enzyme-inhibitory complex is estimated to be 85,000.     

Stable paper indicator systems for rapid identification of microorganisms]

The authors prepared under experimental-industrial conditions paper indicator systems for the express identification of microbes, including carbohydrate discs (by the method of Nikitin et al.), and newly worked out types for the determination of the activity of cytochromoxidase, urease, indol formation, and indicator amino acid decarboxylases (lysin, ornithin, arginine). The use of paper indicator discs proved to be expedient for rationalization of laboratory diagnosis of bacterial intestinal infections.
