The cellular uptake and lysosomal accumulation of 67Ga-labelled transferrin within tumors of different malignancy were examined using tissue fractionation and immunological techniques. As tumor models the slowly growing Morris hepatoma 5123C, the moderately growing Novikoff hepatoma and the fast and aggressive Yoshida hepatoma AH 130 were investigated. Isolation of subcellular fractions of tumor homogenates was performed by differential centrifugation and density-gradient centrifugation. The intracellular 67Gatransferrin was found to be highly concentrated within the purified lysosomes. The transferrin within the lysosomal fraction was identified by radial immunodiffusion technique using monospecific antiserum. The accumulation of 67Gatransferrin by the tumors resulted in a faster disappearance of 67Ga-transferrin from the blood. This loss of circulating 67Ga-transferrin correlated with the proliferation activity and the spread of the tumors. Since transferrin is indispensible for the utilization of iron by the heme-synthesizing red cell precursors, transferrin concentration in the blood is the limiting factor for the utilization of iron in hemoglobin synthesis. Thus, in a further series of experiments we investigated the development of anemia in tumor-bearing rats. With increasing tumor mass a progressive fall of hemoglobin concentration was found. The anemia was more severe in the faster growing Novikoff hepatoma than in the slowly growing Morris hepatoma. The most significant reduction of hemoglobin concentration was found in the very fast growing Yoshida hepatoma. After total tumor resection hemoglobin concentration and red blood cell count normalized completely within 6-8 weeks. We conclude from these data that the uptake of transferrin by the tumor cells results in a faster disappearance of transferrin from the blood. This loss of circulating transferrin correlates with tumor mass and proliferation activity and is one of the factors responsible for the anemia seen in patients with malignant tumors.

The objective of the study is to show significance of desynchronosis laboratory markers in risk assessment of metabolic syndrome (MS) development. Materials and Methods. There were examined 98 men, aged 43-88, diagnosed with dyscirculatory encephalopathy showing one and more risk factors for development of cardiovascular diseases. They were divided into 2 groups according to the international guidelines of 2009: with MS (n = 61) and without MS (n = 37). Parameters of fats, glucose metabolism, inflammatory mediators, fat tissue metabolism markers, melatonin metabolite excretion (6-sulfatoxymelatonin) were defined in blood serum and urine. Results. The article presents data on changes in leptin, adiponectin, PAI-1, testosterone production and 6-sulfatoxymela-tonin excretion in patients with MS. There are calculated threshold values of these markers definitely increasing MS risk and logistic regression equation which allows assessing MS risk for an individual patient. Conclusion. Detected disorders of melatonin synthesis diurnal dynamics in patients with MS and interconnection between melatonin production and adiponectin, leptin, PAI-1, testosterone synthesis allow considering these parameters as desynchronosis markers significant for MS development.

The use of Pediococcus (23×106 CFU/calf/day) orally in drinking milk once daily for one month in Holstein calves have highly significant effect on blood picture ,liver function tests, kidney function test ,blood electrolytes and body weight in cow calves. There were a significant increase in total erythrocytes count , hemoglobin content, packed cell volume, mean corpuscular volume, mean corpuscular hemoglobin, mean corpuscular hemoglobin concentration, thrombocyte count, total leucocytes count, neutrophils counts, eosinophil, basophils, total protein and its fractions, level of alkaline phosphatase (ALP),level of sodium ,calcium ,phosphorus and body weight . On the other hand there were significant decrease in urea and potassium level in groups treated by Pediococcus compared to the control groups. Moreover there were a non-significant changes in lymphocytes, monocytes, creatinine, alanine transaminase (ALT), aspartate transaminase (AST), in the same groups compared to the control groups.
