An erythrocyte suspension in Modegel in the treatment of acute gastrointestinal hemorrhages

The effectiveness of a suspension of erythrocytes in the new colloid preservative "Modegel" (in 1:1 ratio) was studied in the complex treatment of 31 patients with severe gastroduodenal bleedings. It was established that the hemodynamic, antianemic action of the suspension was not inferior (and even excels) to the action of the whole preserved blood and the erythrocytic mass. The suspension transfusion has a favorable effect upon functions of the liver and kidneys, corrects the acidic-alkaline state of the recipients' blood, decreases the lipid peroxidation and has detoxicating properties. During transfusion of the suspension hypocoagulation of blood doesn't take place. The temperature reactions following the suspension transfusion are rare. The suspension of erythrocytes "Modegel" deserves wide introduction to clinical practice.     

Formation of a resting form of Bacillus cereus and Micrococcus luteus

Under certain cultivation conditions, the bacteria Bacillus cereus and Micrococcus luteus form cystlike refractive cells (up to 60% of the total number) that retain viability over a long time, are metabolically inactive and thermotolerant and possess specific ultrastructure. These properties allow them to be attributed to a new type of resting forms of microorganisms.     

The emergence of silent myocardial ischemia as the manifestation of the nitrate withdrawal syndrome in patients with ischemic heart disease

A patient is described, who was examined 1 year after surgery for mandibular cyst diagnosed as radicular near the !5 tooth and for plasty of the secondary osseous cavity with hydroxyapatite granulate. X-Ray examination revealed a cystic cavity near the roots of teeth !234. Histologic examination of tissue fragments and the remainder of hydroxyapatite granulate, obtained by cystectomy, helped diagnose a primordial cyst. Intensive bone regeneration was observed at the site of hydroxyapatite granule accumulation and fusion of the new bone with the granules to form a solid osseogranular complex. The authors recommend hydroxyapatite ceramic granules for surgical treatment of minor and medium bone defects and for corrective bone plasty.
