Aim. To detect changes in the concentration of nitric oxide and its metabolites – nitrites and nitrates in conjunction with the  indices of the glutathione system in  the children with chronic hepatitis В and С.    Patients and methods. In the research took a part 76 patients (boys or girls) with chronic hepatitis В and С aged  from 7 up to 16 years. Nitric oxide and its metabolites  determined by method of V.A. Metel’skaya and N.G. Gumanova; level of  reduced glutathione – the titrimetric analysis; activity of glutathione transferase – the method of spectrophotometry.  Results. The content of nitric oxide and its metabolites– nitrites and nitrates – in serum and urine of children with chronic viral hepatitis В and С have increased. Correlations were revealed between nitric oxide and its metabolites  in serum and urine, as well as between these indices and glutathione system parameters – reduced glutathione concentration and activity of enzymes of glutathione transferase of erythrocytes and plasma. Conclusions. In the children with chronic viral hepatitis В and С the increase of the concentration of  nitric oxide and its metabolites in serum and urine is accompanied by decrease of reduced glutathione concentration and increase of glutathione transferase activity in erythrocytes and plasma. These findings suggest the presence of oxidative stress due to which the therapy should be strengthened by antioxidant effect.

The goal of this work was the research of chondroitin sulfate prophylactic action on the glutathione system state in rat blood serum during acute joint inflammation. The research was performed on white non-linear pubertal rat males weighting 160-240 grams in compliance to all general ethical principles of animal research. All animals were divided to four experimental groups. The first group – the control: the animals were injected with 0,1 ml of 0,9 % NaCl solution in a right hind leg. The second group – rats were subjected to daily intramuscular injections of 3 mg/kg of chondroitin sulfate in the theurapeutic dose during 28 days. The third group – the animals were subjected to daily doses of 0,1 ml of 0,9 % NaCl solution injected in right hind extremities and starting from 29th day the acute joint inflammation was modelled (the animals were subjected to 0,1 ml of 1% of сarrageenan intramuscular injection in right hind extremities. The fourth group – rats were receiving intramuscular injections of therapeutic dose of 3 mg/kg of chondroitin sulfate for 28 days, and after that the acute joint inflammation was modelled starting from 29th day. 40 animals in all were taking part in the experimental research. The glutathione peroxidase activity was assessed judging from the decrease in GSH amount in the reaction with Ellman reagent. The glutathione peroxidase activity was estimated by the decrease in probe optical density owing to NADPH oxidation. Glutathione transferase activity was estimated by the speed of the conjugate formation between GSH and 1-chloro-2,4-dinitrobemzene. The amount of reduced glutathione was estimated spectrophotometrically using orthophthalic aldehyde. It was established that during the carrageenan-induced inflammation the glutathione peroxidase, glutathione reductase and glutathione reductase activity were reduced, a well as the amount of reduced glutathione, whereas the glutathione transferase activity was increased in comparison to the control. It was shown that under the prophylactic injection of the chondroitin sulfate based preparate to animals with acute joint inflammation the aforementioned parameters were partially stabilized.

The purpose of the work is to study a glutathione system (level of reduced glutathione and activity of glutathione-dependent enzymes) in a hemolysate of erythrocytes among the patients with chronic cerebral ischemia (CCI). It was examined 287 patients with CCI and 50 healthy people without any signs of cerebrovascular disease using clinical and neuropsychological, laboratory and instrumental methods of investigation. It was established a significant decrease of the reduced glutathione concentration, the decrease of glutathione reductase and glutathione peroxidase and the increase of glutathione transferase activity in a hemolysate of erythrocytes among the patients with chronic cerebral ischemia in comparison with these rates among healthy people. It was established a negative correlated connection between the level of the reduced glutathione, the age of the patients (r=-0,34, р<0,0001), the stage of discirculatory encephalopathy (DE) (r=-0,50, р<0,0001), intima media complex thickness of carotid arteries (r=-0,29, р=0,009), the level of homocysteine (r=-0,81, р<0,0001) and also the level of glutathione peroxidase, the stage of DE (r=-0,39, р<0,0001) and homocysteine level (r=-0,60, р<0,0001).

Purpose of the study. Exploring the erythrocyte glutathione system functioning in patients with gastric cancer in a comparative aspect, depending on tumor histotype and disease prevalence.Patients and methods. The study included 89 patients with gastric cancer, divided into 6 groups depending on the histotype of the tumor. Separately, the results of the study were analyzed in patients with T4 status according to TNM and in patients at stage 4. The content of reduced glutathione and the activity of glutathione-dependent enzymes in the erythrocytes of the patients' blood were studied by conventional spectrophotometric methods. Statistical processing of the results was carried out using the Statistika 6.0 software package according to the Student's t-test and the nonparametric Wilcoxon-Mann-Whitney test for two independent samples.Results. An increase in the content of glutathione was revealed in patients with gastric cancer compared with the group without oncopathology. The maximum increase was observed in patients with low-grade adenocarcinoma - by 42.5 %, while in signet ring cell carcinoma (SRCC) there was only a tendency to increase by 17.8 %. Glutathione reductase activity was decreased in adenocarcinoma by 23.4-26.2 % and did not change in SRCC. The activity of the antioxidant enzymes glutathione peroxidase and glutathione transferase was increased in all groups, and especially in SRCC - by 76 % and 23-29 %, respectively. In patients with the T4 status and at stage IV of the process, a lower activity of the studied glutathione-dependent enzymes was revealed in comparison with all other groups of patients.Conclusions. The data obtained indicate a greater functional potential of the glutathione system in SRCC. A significant increase in glutathione transferase activity at a sufficiently high level of reduced glutathione can contribute to the development of treatment resistance in SRCC patients.

Abstract Background Chronic hepatitis, mainly B or C, increases the risk of hepatocellular carcinoma and remains an emerging issue in the globe. China has high rates of liver cancer incidence and mortality in the world. To address such challenges, adequate management of chronic hepatitis is required. Self-management education is one alternative for improving the hepatitis patients’ knowledge of the disease, mental health, and clinical management. This study aimed to examine the quality of life (QOL), psychological effects, and behavioral changes of a self-management program which allows continuity of care for chronic hepatitis B and C patients. Method In a six-month, randomized controlled trial, we invited 73 chronic hepatitis B/C inpatients to receive (i) two face-to-face education sessions provided by a nurse during hospitalization, and monthly telephone counseling at home after discharge; (ii) or usual care treatment (control group). The primary endpoint (patients’ QOL) and secondary outcomes (including self-efficacy, depression symptoms, perceived cognition of illness and behavioral changes) were assessed. In addition, we conducted qualitative data analysis to facilitate the evaluation of the interventions. Results Sixty (82.2%) out of 73 eligible patients with chronic hepatitis B/C (aged 34.9 ± 8.9 years) participated in the study. The intervention group (n = 30) significantly improved on outcomes including QOL, self-efficacy, perceived cognition of illness, and behavioral changes, whereas the control group significantly decreased their healthy behaviors. In terms of behavioral changes, alcohol avoidance, dietary adherence, and stress management also improved in the intervention group. However, there were no significant improvements in symptoms of depression. Most participants (80%) in the intervention group stated that they benefited from the program. Conclusions This program contributed to patients’ acquisition of self-management skills to cope with their illnesses, and significantly improved their QOL. This program serves as a reminder for nurses who care for patients with chronic viral hepatitis to acquire these skills as it would help them address the daily needs of their patients.

e16534 Background: The role of oxidative stress in tumor growth and the multifaceted functional significance of glutathione have led to an interest in studying the components of the glutathione-dependent system in gastric cancer (GC), which occupies a leading position in cancer incidence and mortality. The aim of this work was to study the functioning of the glutathione system in the red blood cells of patients with gastric cancer in a comparative aspect depending on the histotype of the tumor and the prevalence of the disease. Methods: The study included 89 patients with GC divided into 6 groups depending on the histotype of the tumor. Separately, the results of the study were analyzed in patients with T4 status according to TNM and in patients with stage IV cancer. The content of reduced glutathione and the activity of glutathione-dependent enzymes were studied by conventional spectrophotometric methods in the red blood cells of patients. Statistical processing of the results was performed using the Statistika 6.0 program with Student’s t-test for two independent groups. Results: An increase in the content of glutathione in patients with GC compared with the group without oncopathology was revealed. The maximum increase was observed in patients with low-grade adenocarcinoma - by 42.5%, while in signet ring cell cancer (SRCC) there was only a tendency to increase by 17.8%. Glutathione reductase activity was reduced in adenocarcinoma by 23.4-26.2% and did not change in SRCC. The activity of the antioxidant enzymes glutathione peroxidase and glutathione transferase was increased in all groups and especially in SRCC - by 76% and 23-29%, respectively. In patients with T4 status and at stage 4 of the process, lower activity of the studied glutathione-dependent enzymes was revealed compared with all other groups of patients. Conclusions: The data indicate a greater functional potential of the glutathione system in SRCC. A significant increase in the activity of glutathione transferase with a sufficiently high level of reduced glutathione contributes to the development of treatment resistance in patients with SRCC.
