[Endovascular surgery in the treatment of patients with myoma uteri]. / Endovaskuliarnaia khirurgiia v lechenii bol'nykh miomami matki.

Forty patients with myoma uteri of varying sites were treated by the new little invasive method - embolization of the uterine arteries. All the patients were admitted to the clinic with the symptoms of the high menstrual blood loss or functional disorders of the pelvic organs. Embolization of the uterine arteries made it possible to achieve good clinical results marked by minimization or removal of the clinical manifestations of myoma uteri.

[Effect of aeration and redox potential on the biosynthesis of the antibiotic imbricin]. / Vliianie aératsii i okislitel'no-vosstanovitel'nogo potentsiala na biosintez protivogribkogo antibiotika imbritsina.

The relationship between imbricin biosynthesis by Streptomyces imbricatus and the medium aeration and redox potential (Eh) was studied. The influence of the oxygen dissolution velocity within the ranges of 2.9 to 0.5 g O2/l.h was investigated and it was shown that the highest yield of the antibiotic was provided by the maximum velocity. At the background of the intensive aeration (2.9 g O2/l.h) decreasing of Eh by reducing agents such as ascorbic acid, L-thyrosin or K4Fe(CN)6 stimulated the biosynthesis whereas at the lower velocities the process proved to be inhibited. Under conditions of insufficient aeration the biosynthesis stimulation could be provided by increasing the medium Eh by acidifying agents such as K2Cr2O7, K3Fe(CN)6 or KMnO4. It was concluded that intensive synthesis of imbricin required not only efficient aeration but also definite levels of the medium redox potential.
