Aim. To compare the clinical course of diabetes mellitus induced by alloxan using classic and modified technique. Methods. Experiments were carried out on mature white mongrel rats, which were divided into two groups: the first group (25 rats) was administered a 200 mg/kg single dose of alloxan (classic model), the second group (25 rats) was administered 150 mg/kg of alloxan at the first day, 100 mg/kg of alloxan at the second day and 100 mg/kg of alloxan at the fourth day. 25 intact rats were examined as a control group. The animals were withdrawn from the experiment by decapitation on the 10th and 21st day, blood and tissue samples were taken for the laboratory testing. The animals’ status (mortality, grooming behavior, body weight, food and water intake) were measured by visual examination. The levels of glucose and lipids were assessed using enzyme colorimetric detection («Human» laboratory kits, Germany, FP-901 analyzer), insulin and C-peptide levels were examined by enzyme-linked immunosorbent assay («Chemwell» analyzer, «DEMENITECKILL-WELLSEE» laboratory kits, Germany); levels of diene conjugates and malonic dialdehyde - using the photocolorimetry based on the colored thiobarbituric acid products. Results. In the first group, the mortality reached 68%, mean weight loss - 41.2%. Blood glucose level at the 10th and 21st days was higher by 370.7 и 146.2% respectively compared to intact animals. Insulin level decreased by 95.8 and 83.7%, C-peptide level - by 96 and 83.7%. In the second group, mortality was 32%, mean body weight loss - 36.5%, blood glucose level at the 10th and 21st days elevated by 364.5 and 151.5%, insulin level decreased by 96.1 and 82.9%, C-peptide level - by 96.0 and 83.7% respectively. A moderate hyperlipidemia was observed in both groups with increased levels of cholesterol, triglycerides, low and very-low density lipoproteids, free fatty acids and decreased levels of high density lipoproteids. The concentration of diene conjugates and malonic dialdehyde increased rapidly to a variable degree depending on the tissue anti-oxidative activity. Conclusion. When diabetes mellitus is modeled by the use of alloxan, an acute form of alloxan-induced diabetes is observed on the 10th day, a chronic form - on the 21st day in both groups. The modified model of alloxan-induced diabetes showed 36% less mortality rate compared to the classic model.

Introduction: Morbid obesity (MO) has a significant impact on mortality, health and quality of life of patients. Type 2 diabetes mellitus (T2DM) is a common comorbidity in patients with MO. The aim is to study T2DM remission and to develop a prediction model for T2DM remission after two-stage surgical treatment of patients with MO. Materials and methods: The study included 97 patients with MO. The mean BMI was 68.08 (95% CI: 66.45 - 69.71) kg/m2. 70 (72,2%) patients with MO were diagnosed with T2DM. The first stage of treatment for the main group (n=60) included the IGB placement, for the control group (n=37) - conservative therapy. In the second stage of treatment the patients underwent bariatric surgery. The study addresses such indicators as BMI, percentage of weight loss, percentage of excess weight loss, ASA physical status class, fasting glucose level, HbA1c, C-peptide. Results: Two-stage treatment of morbidly obese patients with T2DM promotes complete T2DM remission in 68.1% of patients. The risk prediction model for failure to achieve complete T2DM remission 12 months after LRYGB based on a baseline C-peptide level has a high predictive value, AUC = 0.84 (95% CI: 0.69-0.93), OR = 0.23 ( 95% CI: 0.08-0.67). Conclusions: Two-stage treatment of patients with MO promotes improvement of carbohydrate metabolism indicators. With a C-peptide level > 3.7 ng/ml, prediction of complete T2DM remission 12 months after Laparoscopic Roux-en-Y Gastric Bypass is favorable.

Цель - оценка влияния препаратов суммарной РНК лимфоидных клеток на уровень глюкозы в крови при экспериментальном аллоксановом диабете. Методика. Работа выполнена на 68 белых беспородных крысах обоего пола массой 180-220 г. Для моделирования аллоксанового сахарного диабета 1 типа животным однократно подкожно вводили полный адъювант Фрейнда в дозе 0,5 мл/крысу. Через 24 ч (на фоне 24-часового голодания, при свободном доступе к воде) однократно подкожно вводили препарат аллоксан тригидрат («La Chema», Чехия) в дозе 200 мг/кг (4% раствор в 0,9% NaCl). Для предотвращения фатального кетоацидоза, начиная с 3-х сут после введения аллоксана, все крысы получали базисную инсулинотерапию. В экспериментах использовано 8 разновидностей препаратов суммарной РНК: из лимфоидных клеток селезенки, из костного мозга и хвостовой части поджелудочной железы интактных крыс (РНКс-1, РНКкм-1 и РНКп/ж, соответственно); из лимфоидных клеток селезенки крыс, подвергнутых кровопусканию в объеме 2% от массы тела за 17 ч до выделения РНК (РНКс-2 с индуцированной повышенной морфогенетической активностью); из лимфоидных клеток селезенки и тимуса крыс, подвергнутых кровопусканию в объеме 2% от массы тела за 96 ч до выделения РНК (РНКс-3 и РНКт-3, соответственно, с высокой ингибирующей морфогенез активностью); из лимфоцитов периферической крови здорового человека (РНКлпкч), а также из стволовых клеток стромы пупочного канатика человека. Результаты. Показана возможность восстановления функции инсулярного аппарата и стойкой нормализации уровня глюкозы в крови крыс с экспериментальным аллоксановым диабетом 1 типа. Установлено наличие корригирующей способности аллогенных и ксеногенных препаратов суммарной РНК, выделенной из лимфоидных органов крыс и лимфоцитов периферической крови человека, а также из мезенхимных стромальных клеток пуповины человека, в отношении уровня глюкозы крови у крыс. Продемонстрирован различный вклад препаратов суммарной РНК, полученной из разных лимфоидных органов и стволовых клеток, в восстановлении нормального уровня глюкозы в крови животных. Установлено, что указанные препараты действуют на разные ткани-мишени в процессе восстановления функции инсулярного аппарата. Заключение. Полученные данные свидетельствуют о принципиальной возможности эффективного лечения сахарного диабета 1 и 2 типов. Доказана эффективность неинвазивного интраназального введения аллогенных и ксеногенных препаратов суммарной РНК лимфоидных и стволовых клеток. Полученные результаты ставят вопрос о необходимости разработки более адекватной экспериментальной модели, а также о перспективности поиска подходов к персонифицированному индивидуальному лечению этой патологии с учетом особенностей ее развития в каждом конкретном случае. Aim. To study the effect of total RNA from lymphoid cells on blood glucose in experimental alloxan diabetes mellitus (DM). Methods. The study was conducted on 68 white mongrel rats of both sexes weighing 180-220 g. Alloxan DM was modeled with full Freund’s adjuvant (0.5 ml/rat). After 24 h of fasting with free access to water, a single dose of alloxan trihydrate (La Chemas, Czeck Republic) was injected subcutaneously (200 mg/kg as a 4% solution in saline). All rats received basis insulin therapy starting from day 3 of the alloxan injection to prevent fatal ketoacidosis. Eight types of total RNA were used: from splenic lymphoid cells, bone marrow, and caudal part of the pancreas of intact rats; from splenic lymphoid cells of rats after blood withdrawal (2% of body weight 17 h prior to RNA isolation) (RNA after induction of increased morphogenetic activity); from splenic and thymic lymphoid cells of rats after blood withdrawal (2% of body weight 96 h prior to RNA isolation) (RNAs with high morphogenesis-inhibiting activity); and from peripheral blood lymphocytes and umbilical cord stromal stem cells of a healthy human. Results. The study showed a possibility for functional recovery of the insular apparatus and stable normalization of blood glucose level in rats with experimental alloxan DM, a model of clinical type 1 DM. Allogenic and xenogeneic total RNAs isolated from rat lymphoid organs, peripheral blood lymphocytes, and mesenchymal stromal cells of human umbilical cord were able to correct the blood glucose level in rats. Total RNAs isolated from different lymphoid organs and stem cells differently contributed to normalization of blood glucose in rats. These total RNAs were shown to influence different target tissues during restoration of the insular apparatus function. Conclusion. The study showed a principle possibility of effective therapy for types 1 and 2 DM and demonstrated the efficacy of non-invasive intranasal administration of allogenic and xenogeneic total RNAs from lymphoid and stem cells. These results indicated a need for developing a more relevant experimental model and offered a promising outlook for individualized treatment of this disease with due account of its peculiar features in each specific case. The study was conducted as a part of the Program for Basic Research of State Academies of Science in 2013-2020 on Development of Cell Models for Molecular Processes in Organs and Tissue (V.N. Orekhovich Research Institute of Biomedical Chemistry) and the complex Research Work #01201354257 on Regulation of Hemopoietic and Nonhemopoietic Functions of Bone Marrow Cells in Experiment and Clinic (Sounth Ural State Medical University).

Background: Diabetes Mellitus is one of the leading cause of morbidity and mortality globally. According to WHO there is a steady increase in the number of diabetic patients annually. Maintenance of good glycaemic control in type 2 diabetic patients typically becomes progressively more difficult as the duration of disease lengthens due to decline in the capacity of the pancreatic beta cells for glucose stimulated insulin release, in the presence of insulin resistance. This study is conducted to observe the effect of metformin and bromocriptine individually and sub-therapeutic doses of these drugs when used as a combination therapy. Objective: The objective of this study is to primarily investigate and then compare the antihyperglycemic effects of bromocriptine with metformin, also to see the combined effect of sub therapeutic doses of both these drugs. Methodology: Random allotment of 24 albino male rats was done in four groups. Group 1 was kept as control. Alloxan monohydrate was given to group 2, 3 and 4 and diabetes was induced. Group 2 and 3 were treated with metformin (1.5mg/kg body weight) and bromocriptine (3 mg/kg body weight) respectively while group 4 was treated with sub therapeutic doses of metformin (1 mg/kg body weight) and bromocriptine (1.5 mg/kg body weight)both. Serum glucose levels were estimated at 1, 10, 20 and 30 days. Results: Results showed that metformin reduces blood glucose level significantly where as bromocriptine also showed reduction of blood glucose level but not as significantly as metformin. However, the combination of metformin and bromocriptine showed much reduction in blood glucose level than metformin and bromocriptine used alone. Conclusion: Bromocriptine and metformin when combined ameliorated blood guclose efficiently than given alone Keywords: Diabetes mellitus, bromocriptine, metformin

Progressive Weight Loss

Objective: To observe the changes of lipid metabolism, blood glucose level and insulin sensitivity in patients with Type-2 diabetes after progressive weight loss of their body weight, so as to lay a theoretical foundation for diabetes treatment and education in the future. Methods: One hundred obese patients with Type-2 diabetes (BMI ≥ 25 kg/m2) who visited the endocrinology department of our hospital from April 2017 to April 2018 were given diabetes health education, diabetic diet, exercise and other measures to control their weight. The changes of blood glucose, blood lipid, insulin level and insulin release test before weight loss (T1), and at the time points of weight loss reached 5% (T2), 10% (T3) and 15% (T4) were recorded respectively to understand the influence of progressive weight loss on relevant indexes of patients. Results: With the decrease of body weight, the differences of TC, TG, LDL-C and HDL-C at different weight loss points were significant (p < 0.05), and the changes of fasting blood glucose in 5% and 10% weight loss were significant (p = 0.02). The 2h postprandial blood glucose showed the most significant difference when the weight loss reached 15% (p = 0.00). There was no statistical difference in the change of glycosylated hemoglobin among different weight loss points (p = 0.08). When the weight loss reached 10%, the blood insulin level was significantly lower than that before the weight loss, while the insulin level was not significantly changed when the weight loss reached 15%, but the peak of secretion was shifted forward. It is suggested that insulin sensitivity gradually increases with weight loss. Conclusion: Obese patients with Type-2 diabetes can benefit from weight loss, with abnormal blood glucose and lipid metabolism improved, insulin resistance relieved, and insulin sensitivity increased. doi: https://doi.org/10.12669/pjms.36.7.3027 How to cite this:Kong DX, Xiao Y, Zhang Z, Liu Y.

Antihyperglycemic activity of leave extracts of Ficus carica was evaluated on STZ induced diabetic rats. Diabetes was induced in albino Wistar rats of either sex by intraperitoneal (60mg/kg b.w.) of STZ, freshly dissolved in citrate buffer (0.01 M, pH 4.5). Ficus carica leave extract in different solution (viz. petroleum ether, ethyloacetate, methanol and aqueous) were administered to diabetic rats for 9 days. The effect of extracts on blood glucose and body weight was studies on day 1st and 9th. The study showed that the ethyl acetate, methanolic and aqueous extract of Ficus sarmentosa leaves reduced blood glucose level and body weight significantly. This may justify the use of ficus species as ethanomedical medicine for treatment of diabetes mellitus.

Introduction: There is a need to develop diabetic animal model, to have a better understanding of the complications of diabetes mellitus. The dose of Streptozotocin (STZ) to induce diabetes mellitus in animals is important as it may lead to inadequate induction of diabetes or mortality. Intravenous injection of STZ in adult Wistar rats, leads to the degeneration in Langerhans islet β-cells and induces experimental diabetes mellitus in 3-5 days. Aim: To optimise the dose of STZ to create a diabetic animal model with sustained hyperglycaemia and to compare the changes in body weight, serum glucose and C-peptide levels between non diabetic and diabetic rats. Materials and Methods: This experimental animal study was conducted at animal house, Pal amur Bioscience Pvt., Ltd. The sample size included 30 albino Wistar rats divided into five groups T0, T1, T2, T3 and T4 with six rats in each group (three males and three females). Group T0 was the control, while STZ at different concentrations were administered intraperitoneally in group T1, T2, T3 and T4, respectively. Blood samples were drawn from retro-orbital plexus of animals and blood glucose, C-peptide levels along with the body weight was checked on 7th, 14th, 21st and 28th day. The F statistics, one-way Analysis of variance (ANOVA) was used to compare the different groups. Denny’s test was used to compare the control group versus different test groups. Results: When compared with the control group T0 on 7th, 14th, 21st and 28th day, the test group T1 had no variation in the body weight. On the other hand groups T2, T3 and T4 had variations in the body weights. Initially there was increase in the weight, later here was a gradual decrease in the body weight when compared to the control group. Hyperglycaemic profile (blood glucose level >120 mg/dL) was achieved in group T1, T2, T3 and T4 after 7 days. High mortality rate was observed in group T4 followed by group T3. Group T2 had persistent hyperglycaemia while group T1 had reversible hyperglycaemic profile. The C-peptide levels were gradually decreased in the test groups and it was statistically significant (p-value <0.0001). Conclusion: Intraperitoneal dose of STZ of 55 mg/kg created diabetic animal model with persistent hyperglycaemia. However, dose above increased the mortality rate and below failed to create diabetic animal model.
