Influence of Complex Treatment on the Functional State of the Hepatobiliary System in Patients with Diabetes Mellitus

Liver damage in diabetes mellitus is of particular interest, since this factor significantly affects the course of the disease, the level of compensation and prognosis of the underlying disease. The aim. To study the effect of complex treatment using ursosan on the functional state of the hepatobiliary system in patients with diabetes mellitus. Materials and methods. The study included 30 patients with type 1 diabetes mellitus and 48 patients with type 2 diabetes. According to the duration of diabetes, patients were divided into three subgroups: a) up to five years; b) 5–10 years; c) more than 10 years. The number of patients was: 1a group – 13, 1b group – 10, 1c group – 7 people; Group 2a – 23, 2b group – 13, 2c group – 10 people. The control group consisted of 23 apparently healthy people. Ursosan was prescribed at a dose of 10-12 mg per 1 kg of body per day for 6 months. Clinical laboratory and instrumental research methods were used to study the functional state of the liver and gallbladder. Research results. After the course of treatment with Ursosan, patients with diabetes mellitus showed normalization of protein, pigment, enzymatic metabolism and, to a lesser extent, lipid metabolism in the liver, which led to an improvement in cellular metabolism and redox processes, providing a stable course of diabetes. Conclusions. A 6-month course of treatment with Ursosan in diabetic patients promotes long-term diabetes compensation. Patients during treatment have a decrease in cytolysis syndrome indicators (alanine aminotransferase (AlAT), aspartate aminotransferase (AsAT), lactate dehydrogenesis (LDH)) by about 1.5 times in all 3 indicators compared to the indicators before treatment. The same trend was observed in terms of gamma-glutamine transferase (GGT) and alkaline phosphatase (ALP

Synthesis of Fe/Ni Bimetallic Nanoparticles and Application to the Catalytic Removal of Nitrates from Water

This work investigated the effectiveness of zerovalent iron and Fe/Ni bimetallic nanoparticles in the treatment of water polluted by a high concentration of nitrates. Nanoparticle synthesis was carried out by a sodium borohydride reduction method in the presence of sodium oleate as a surfactant. The particles were characterized by XRD and SEM. Batch experiments were conducted on water samples contaminated by 300 mg L−1 of nitrate. The parameters investigated were the Fe/Ni dosage (0.05, 0.1, 0.2, 0.3, and 0.4 g L−1) and the reaction pH (unbuffered; buffered at pH = 3; initial pH = 3, 5, and 10). The results showed that almost complete nitrate removal (>99.8%) was always achieved after 15 min at a concentration of bimetallic nanoparticles higher than 0.2 g L−1. The optimization of bimetallic nanoparticle dosage was carried out at a fixed pH. Kinetic study tests were then performed at different temperatures to assess the effect of temperature on the nitrate removal rate. By fixing the pH at acidic values and with an operating temperature of 303 K, nitrates were completely removed after 1 min of treatment
