Effect of local oxygen therapy on reparative regeneration of the bone

An apocrine hidrocystoma of the shoulder of a 59-year-old woman is, to our knowledge, only the third reported case that arose outside of the head and genitalia. Its origin was nonetheless consistent with the distribution of apocrine glands in adults.     

The laparoscopic sterilization of women

The optimal time for sterilization is 24-36 hours after childbirth or during the 8th week in the postpartum period. The surgical methods of sterilization of the ovarian ducts are simple, harmless, effective, reversible, economical, and voluntary. These considerations also apply to endoscopic methods. For the occlusion of ovarian ducts, electrical current (monopolar and bipolar) and mechanical means (Yoon ring, Hulka and Filshie clips) are used. Unipolar coagulation of the ovarian ducts is another method of surgical sterilization done by laparoscopy. The area of coagulation occupies about 1.5 cm. The length of bipolar coagulation is 10 times larger than the unipolar coagulation site. Patients can be released 4 hours or the next day after the operation. The frequency of complications with bipolar coagulation is low: burning occurs in 0.04-0.1% of cases and bleeding from the mesosalpinx in 0.16-0.5%. The incidence of pregnancy after the operation amounts to 0.1-0.4%. Mechanical methods of sterilization are also reliable, although they are not suitable for all women. For young women who may still want children it is uniquely expedient to employ the Hulka or Filshie clips. In the rest of the cases the Yoon ring can be used, which was first used in the US in 1972 and became popular subsequently. The rate of complications is rare with its use (0.12-3.75%), and pregnancy occurs in 0.08-0.4% of cases. The incidence of complications with the use of clips amounts to 0-0.71%, the pregnancy rate is 0-0.59%, and the possibility of reversal is 80-100%. This method is ideal for young women who do not want to use other contraceptives and who want to have more children.     

The internal structure of soft and bony tissues studied by X-ray refraction introscopy]

The change of electrophoretic mobility (EPM) of erythrocytes of donor blood caused by their incubations with the bee venom and its major components--melittin and phospholipase A2 was investigated. It was estimated that the bee venom reversibly decreased EPM of erythrocytes to the higher degree than its separate components. The reaction was completely abolished after preliminary processing of erythrocytes with neuroaminidase and partly after their processing with glutaraldehyde, but the effect of EPM increased under the conditions of the increasing of ATP concentration. Proceeding from the authors' data it was concluded that the major components of the bee venom successively interacted with glicocalyx elements and membrane of erythrocytes which evokes the charge redistribution in these blood cells.     

The radioprotective effect of hypoxia on clonogenic cells of rat bone marrow stroma (KOE-F)]

A comparative study was made on the survival rate of cell-precursors of haemopoietic stroma, that form, in a rat bone marrow culture, colonies (clones) of fibroblasts (CFU-F) after gamma-irradiation of animals in the air or in a gas hypoxic mixture, containing 8% of O2 (GHM-8). Irradiation in GHM-8 was shown to increase the survival rate of CFU-F by 1.7 times (as compared to exposure in the air) as estimated by the total number of colonies that are formed in a culture; the radioprotective effect of GHM-8 was more pronounced for CFU-F which form dense colonies: DMF for dense and loose clones was 2.4 and 1.6 respectively.     

The choice of an optimal variant in the reconstructive stage of gastrectomy]

The authors analyse 40-year experience in gastrectomy and extirpation of the gastric stump in carcinoma of the stomach. Operations were performed on 742 patients. The results show that the mechanical suture has advantages over the manual suture in the formation of the esophago-intestinal anastomosis. The functional results were found to be best when the continuity of the gastrointestinal tract was restored by establishing the esophago-intestinal anastomosis with a loop of the small intestine isolated according to Roux. Comparative appraisal of end-to-end and end-to-side esophago-intestinal anastomoses revealed the advantages of the last-named in relation to the incidence of postoperative complications and total outcomes. The effect of the surgeon's qualification on the frequency of postoperative complications is discussed.     

New developments in understanding the compensatory hematological reactions and their outcomes in local fractionated therapeutic gamma irradiation

A surgical treatment for central epithelial odontogenic ghost cell tumor is described. A brief review of the literature is given, and histopathology is discussed. The rationale for conservative treatment is presented, along with an illustrative case report.     

Comparative characteristics of the effect of benzylpenicillin on the biosynthesis of postvaccinal antibodies after oral and intramuscular administration

A technique is described for the preparation of intact colonies of Dermatophilus and their study under the scanning electron microscope. Using this technique with 38 strains of the organism it is possible to describe for the first time the patterns of colony morphology and to study the relationship of hyphae, cocci and zoospores in situ. Colonies were found to possess both vegetative and aerial hyphae. The various patterns of mycelial activity and structure that were seen raised serious doubts about the previous concepts of the mode of propagation and thus the classification of Dermatophilus within the Actinomycetales.
