Antitumor effect of arabinogalactan and platinum complex.

The article presents the results of investigation of antitumor properties of platinum-arabinogalactan complex. We showed the ability of the complex to inhibit the growth of Ehrlich ascites tumor cells. It is found that the distribution of the platinum-arabinogalactan complex is not specific only for tumor cells in mice. The complex was found in all tissues and organs examined (ascites cells, embryonic cells, kidney, and liver). The mechanism of action of the arabinogalactan-platinum complex may be similar to cisplatin as the complex is able to accumulate in tumor cells.

[Chemiluminescent and enzyme activity of neutrophils in patients with widespread purulent peritonitis depending on the outcome of disease].

BACKGROUND: Aim was to study the chemiluminescent activity and the activity of NAD- and NADP-dependent dehydrogenases of neutrophils depending on the outcome of the widespread purulent peritonitis (WPP). PATIENTS AND METHODS: 51 patients with a mean age of RSE 54.2 ± 19.2 years were observed. As a control 75 healthy people of similar age range were examined. Lucigenin- and luminol-dependent chemiluminescence activity and activity of NAD(P)-dependent dehydrogenases peripheral blood neutrophils were studied. RESULTS: In patients with a favorable outcome of WPP the maximum intensity increased and the magnitude of the activation index of lucigenine-dependent spontaneous chemiluminescence reduced. Regardless to the outcome of WPP in patients with increased activation index and maxima of the luminol-dependent spontaneous and zymosan-induced chemiluminescence. At the unfavorable outcome of the disease in neutrophils NAD- dependent isositrate dehydrogenase and anaerobic lactate dehydrogenase reaction activity increased. Regardless to the outcome WPP in patients neutrophils aerobic reaction of lactate dehydrogenase, glucose-6-phosphate dehydrogenase and NADP-dependent glutamate dehydrogenase activity reduced but levels of NADH-dependent reaction of malate dehydrogenase, NADH-dependent glutamate dehydrogenase and NADP-dependent isocitrate dehydrogenase activity increased. CONCLUSION: With the reduction of the intensity ofplastic processes and imbalances enzymatic activity in nitrogen metabolism in patients with WPP at unfavorable outcome of the disease increases the activity of enzymes that characterize the level of anaerobic and aerobic respiration. In the absence of marked changes in the activity of enzymes that characterize the level of energy processes in cells of patients with favorable outcome of the WPP, increases the intensity of spontaneous lucigenin-dependent chemiluminescence and reduced neutrophil activation index.
