Background: The liver plays an important role in nutrient metabolism and alterations in the liver function, biliary secretion and cytoachitecture are common in diabetes mellitus (DM). Aim: Ocimum gratissimum (OG) has been reported to exert hypoglycaemic effect in DM, the need to assess the impact of its treatment on these diabetic complications became imperative. Material and Methods: Phytochemical and toxicity test were conducted. Eighteen rats into three groups of six rats each were used. Group 1 was the control and given normal feed only. Group 2 was diabetic untreated rats (DM) while group 3 was OG treated diabetic rats (DMT) at a dose of 1500 mg/kg. All groups had access to food and water ad libitum. After 28 days, serum was obtained for analysis of Alkaline phosphatase (ALP), Alanine aminotransferase (ALT) and Aspartate aminotranferase (AST). The bile content was collected at 3 hours interval to determine the bile secretory rate. Routine biopsy method was employed for histological studies. Results: Results showed that AST in the DM and DMT groups were significantly higher (P < 0.001) than the control group; DM was significantly higher (P < 0.001) than the DMT. ALT and ALP levels in DM and DMT groups were significantly (P < 0.001) higher than the control; DM was significantly higher (P < 0.001) than DMT. Conclusion: There was structural and functional hepatic impairment in DM. OG treatment appears to effectively ameliorate these complications including enhancement of bile secretion.DOI: http://dx.doi.org/10.3126/ajms.v6i3.9960Asian Journal of Medical Sciences Vol.6(3) 2015 16-21

Background: There is a growing interest in the correlation between antioxidants and periodontal disease. In this study, we aimed to investigate the effect of oxidative stress and the impact of two antioxidants, curcumin and rutin, respectively, in the etiopathology of experimentally induced periodontitis in diabetic rats. Methods: Fifty Wistar albino rats were randomly divided into five groups and were induced with diabetes mellitus and periodontitis: (1) (CONTROL)—control group, (2) (DPP)—experimentally induced diabetes mellitus and periodontitis, (3) (DPC)—experimentally induced diabetes mellitus and periodontitis treated with curcumin (C), (4) (DPR)—experimentally induced diabetes mellitus and periodontitis treated with rutin (R) and (5) (DPCR)—experimentally induced diabetes mellitus and periodontitis treated with C and R. We evaluated malondialdehyde (MDA) as a biomarker of oxidative stress and reduced glutathione (GSH), oxidized glutathione (GSSG), GSH/GSSG and catalase (CAT) as biomarkers of the antioxidant capacity in blood harvested from the animals we tested. The MDA levels and CAT activities were also evaluated in the gingival tissue. Results: The control group effect was statistically significantly different from any other groups, regardless of whether or not the treatment was applied. There was also a significant difference between the untreated group and the three treatment groups for variables MDA, GSH, GSSG, GSH/GSSG and CAT. There was no significant difference in the mean effect for the MDA, GSH, GSSG, GSH/GSSG and CAT variables in the treated groups of rats with curcumin, rutin and the combination of curcumin and rutin. Conclusions: The oral administration of curcumin and rutin, single or combined, could reduce the oxidative stress and enhance the antioxidant status in hyperglycemic periodontitis rats.

This research investigated the chemical analysis and sensory evaluation of low-calorie formulated pumpkin jams after storage for six months and the effects of the consumption of low-calorie jams on diabetic rats. Pumpkin jam with sucrose, fructose, stevia, and aspartame sweeteners and soybean was prepared and stored at 10°C for six months. Rats were divided into group 1 (negative control), group 2 (positive diabetic groups), and groups 3, 4, and 5 (diabetic groups treated with 10% sucrose, fructose, and stevia soybean jam, respectively). The results indicated that the contents of protein, fat, ash, and fibre were increased in the low-calorie formulated pumpkin jams. The highest sensory scores were recorded for sucrose and fructose soybean jams and then for stevia soybean jam, while the aspartame soybean jam showed significantly lower scores after storage for 3 and 6 months. Rat groups 4 and 5 showed significant decreases in the glucose level, and liver function enzymes activity showed significant increases in insulin and glycogen levels compared to group 2. Conclusion. Low-calorie pumpkin jams with soybean can be stored for 3 months at 10°C without any change. Stevia pumpkin jam with soybean has antidiabetic effects.

Введение. Сосудистые осложнения сахарного диабета (СД) являются одной из ведущих причин повышения смертности пациентов трудоспособного возраста. Предполагается, что индуцированный гипергликемией окислительный стресс и нарушение антиоксидантной защиты играют роль в патологическом механизме повреждения сосудов, частично за счет влияния оксида азота (NО). Цель исследования: уточнение взаимосвязей в системах асимметричного диметиларгинина (АДМА) и NO у пациентов с цереброваскулярными заболеваниями (ЦВЗ) на фоне СД 2-го типа (СД-2). Материалы и методы. Обследованы 72 пациента с ЦВЗ со стенозирующим поражением внутренней сонной артерии вне острого периода: группу 1 составили 39 пациентов (18 мужчин и 21 женщина) с СД-2 в возрасте 65 [58; 72] лет; в группу 2 вошли 33 больных (15 мужчин и 18 женщин) без СД-2 в возрасте 66 [56; 74] лет. Контрольную группу составили 30 добровольцев (16 мужчин и 14 женщин) без проявлений церебральной ишемии и нарушений углеводного обмена, с нормальными значениями индекса массы тела, некурящие, в возрасте 62 [50; 66] лет. Проводилось клиническое обследование, нейро- и ангиовизуализационное исследование, спектр биохимических исследований крови, в том числе определение содержания АДМА и показателей системы NO. Результаты. В группе 1 содержание нитрата, нитрита и NO составило 62,1 [56; 68] мкмоль/л, 48,5 [26; 52] мкмоль/л и 13,6 [9; 23] мкмоль/л соответственно, что достоверно отличалось от значений этих показателей в группе 2 — 58,3 [45; 64] мкмоль/л, 39,6 [26,0; 42,3] мкмоль/л и 18,7 [16,1; 24,7] мкмоль/л соответственно. Отмечен также более высокий уровень AДМА в крови у пациентов с ЦВЗ в сочетании с СД-2 — 0,42 [0,21; 0,53] ммоль/л. Заключение. Обнаружена взаимосвязь между уровнями AДМА и NO при ЦВЗ на фоне СД-2. Это требует продолжения исследований биомаркеров повреждения сосудистой стенки для определения их места в патогенезе ишемических церебральных осложнений СД-2. Background. Vascular complications of diabetes mellitus (DM) are one of the leading causes of increased mortality in patients of employable age. Hyperglycemia-induced oxidative stress and impaired antioxidant protection have been suggested to play a role in the pathological mechanism of vascular damage, in part due to the effects of nitric oxide (NO). Objectives: clarification of relationships in the systems of asymmetric dimethylarginine (ADMA) and NO in patients with cerebrovascular diseases (CVD) and type 2 diabetes (DM-2). Patients/Methods. We examined 72 CVD patients with stenosing lesions of the internal carotid artery outside the acute period: group 1 consisted of 39 patients (18 men and 21 women; 65 [58; 72] years old) with DM-2; group 2 consisted of 33 patients (15 men and 18 women; 66 [56; 74] years old) without DM-2. The control group consisted of 30 volunteers (16 men and 14 women; 62 [50; 66] years old) without manifestations of cerebral ischemia and carbohydrate metabolism disorders, with normal body mass index, non-smokers. A clinical examination, neuro- and angio-imaging study, a spectrum of biochemical blood tests, including the concentration of asymmetric dimethylarginine (ADMA) and indicators of NO system were carried out. Results. In group 1, the content of nitrate, nitrite and NO was 62.1 [56; 68] μmol/l, 48.5 [26; 52] μmol/l and 13.6 [9; 23] μmol/l, respectively, that significantly differed from the content of these parameters in group 2 — 58.3 [45; 64] μmol/l, 39.6 [26.0; 42.3] μmol/l and 18.7 [16.1; 24.7] μmol/l, respectively. Noted also a higher blood level of ADMA in patients with CVD combined with DM-2 — 0.42 [0.21; 0.53] mmol/l. Conclusions. A relationship was found between ADMA and NO levels in CVD patients with DM-2. This requires further studies of biomarkers of vascular wall damage to determine their place in the pathogenesis of ischemic cerebral complications of DM-2.

In diabetes mellitus, non-alcoholic fatty liver disease (NAFLD) is closely linked to hyperglycemia metabolism. This study aimed to find out how a banana peel supplemented diet affected histological and liver function changes in streptozotocin-induced diabetic rats. Vitamins, minerals, dietary fiber, antioxidants, and tryptophan are all contained in banana peel flour (BPF). Serotonin is a neurotransmitter that has been linked to depression and anxiety. This post-test-only control group study was conducted on twenty-five male Wistar rats which were separated into five groups with different treatments. Groups II to V were diabetic rats model groups that consumed standard diet mixed with BPF 0%, 5%, 10%, and 20%, respectively, while group I was a healthy control group fed a standard diet. Hepatic enzyme transaminase (Alanine Aminotransferase-ALT and Aspartate Aminotransferase - AST) and Hematoxylin-Eosin (HE) staining were analyzed with the NAFLD score to examine the liver function and hepatocellular morphology. A change in liver function was observed, as well as a substantial change in the levels of ALT and AST. The NAFLD score with HE staining showed substantial improvements in liver morphology, which was better seen at a 20% BPF dose. The current study supported the hypothesis that BPF had a hepatoprotective effect in diabetic rats, which may be due to the mechanism of controlling the hepatic enzyme transaminase and inducing liver regeneration.

ABSTRACT Objectives Long-term therapy with low-dose methotrexate (MTX) is widely used in treatment of rheumatic diseases, in children. The purpose of this study was to evaluate liver elasticity in patients with juvenile idiopathic arthritis (JIA) who received MTX and compare the results with control group. Methods Liver elasticity was evaluated with shear wave elastography (SWE) technique in 25 patients aged 3–17 years who were followed up with JIA and received MTX and compared with 25 healthy controls of the same age and weight. Factors that had an effect on liver elasticity were examined. Results The mean SWE value of patients was 2.64 ± 2.13 m/s and 24.10 ± 18.50 kPa, whereas 1.83 ± 0.16 m/s and 10.09 ± 1.83 kPa in control group. There was a significant difference in liver elasticity in the patient and control groups. When the patients were evaluated as Group 1 (&lt; 1000 mg) and Group 2 (≥ 1000 mg) according to the cumulative MTX dose, no significant difference was obtained. There was positive correlation between liver elasticity and weekly MTX dose and age. Conclusions Our study revealed that liver elasticity significantly decreased in patients who received MTX when compared with the control group. The elastography technique will be understood better over time and used safely in many areas.

Abstract. INFLUENCE OF HORMONAL DISORDERS ON ENDOTHELIAL DYSFUNCTION IN PATIENTS WITH ARTERIAL HYPERTENSION AND COMORBIDE ENDOCRINOPATHIES Bilovol O.M., Nemtsova V.D., Ilchenko I.A., Zlatkina V.V. Purpose: to investigate the effect of hormonal changes on endothelial dysfunction (ED) in patients with a comorbid course of hypertension (H), type 2 diabetes mellitus (T2DM) and subclinical hypothyroidism (SHT). Methods: 183 patients with  H stage II were divided into 3 groups: Group 1 (n=50) - with isolated H (comparison group); Group 2 (n=63) - with a combined course of H and T2DM; Group 3 (n=70) - with comorbidity of H, T2DM and SHT. Blood pressure levels, carbohydrate, lipid and thyroid metabolism, plasma insulin concentration, insulin resistance (IR) the HOMA-IR index, vascular endothelial growth factor (VEGF-A) plasma levels were investigated. Results: Dyslipidemia was more pronounced in group 2 than in group 1. The addition of SHT was accompanied by a tendency to increase all the atherogenic lipids. IR was observed in all patients groups and was significantly higher than in control group (p<0.05). Significant increase of VEGF-A levels in all patients groups in comparison with the control (p<0.05) was found. In group 2 VEGF-A was lower than in group 1, which is probably due to the protective effect of metformin. Analysis  of the influence of thyroid dysfunction degree on ED revealed significant increase of VEGF-A levels in TSH>6.0 μMU/ml subgroup (352.55±17.64 pg/ml vs 461.74±20.13 pg/ml (p<0.05)). Conclusion: Hormonal disorders contribute to aggravation of endothelial dysfunction in patients with hypertension and comorbid endocrinopathies - type 2 diabetes mellitus and subclinical hypothyroidism. Even minor decrease in thyroid function lead to the progression of endothelial dysfunction. Key words: hypertension, type 2 diabetes mellitus, subclinical hypothyroidism, endothelial dysfunction   Резюме. ВПЛИВ ГОРМОНАЛЬНИХ ПОРУШЕНЬ НА ЕНДОТЕЛІАЛЬНУ ДИСФУНКЦІЮ УПАЦІЄНТІВ З АРТЕРІАЛЬНОЮ ГІПЕРТЕНЗІЄЮ ТА КОМОРБІДНИМИ ЕНДОКРИНОПАТІЯМИ Біловол О.М., Немцова В.Д., Ільченко І.А., Златкіна В.В. Мета: дослідити вплив гормональних змін на ендотеліальну дисфункцію (ЕД) у пацієнтів з коморбідним перебігом артеріальної гіпертензії (АГ), цукрового діабету 2 типу (ЦД2Т) тасубклінічного гіпотиреозу (СГТ). Матеріали та методи: 183 пацієнта з АГ II стадії були розділені на 3 групи: 1-а група (n=50) - з ізольованою АГ (група порівняння); Група 2 (n=63) - з поєднаним перебігом АГ та ЦД2Т; Група 3 (n 70) – з комбінованим перебігом АГ, ЦД2Т і СГТ. Вивчали рівні артеріального тиску, показники вуглеводного, ліпідного і тиреоїдного обміну, концентрацію інсуліну в плазмі, індекс інсулінорезистентності (ІР) - HOMA-IR, рівні васкулоендотеліального фактора росту (VEGF-A) в плазмі. Результати. Ступінь дисліпідемії у 2-й групі була більш вираженою, ніж в 1-й. Приєднання СГТ супроводжувалося тенденцією до збільшення всіх атерогенних фракцій ліпідів. ІР спостерігалася у всіх групах пацієнтів і була достовірно більше, ніж у контрольній групі (р<0,05). Виявлено достовірне підвищення рівнів VEGF-A у всіх групах пацієнтів в порівнянні з контролем (р<0,05). В 2-й групі рівні VEGF-A були нижче, ніж в 1-й групі, що, ймовірно, пов'язано з протективним ефектом метформіну. Аналіз впливу ступеня гіпофункції щитовидної залози на ЕД виявив значне збільшення рівнів VEGF-A в підгрупі TSH> 6,0 мкМ / мл (352,55 ± 17,64 пг / мл і 461,74 ± 20,13 пг / мл відповідно, р <0,05). Висновки.

Background: Diabetes mellitus deeply changes the genes expression of integrin (Itg) subunits in several cells and tissues such as monocytes, arterial endothelium, kidney glomerular cells, retina. Furthermore, hyperglycemia could impress and reduce the rate of successful assisted as well as non-assisted pregnancy. Endometrium undergoes thorough changes in normal menstrual cycle and the question is: What happens in the endometrium under diabetic condition? Objective: The aim of the current study was to investigate the endometrial gene expression of α3, α4, αv, Itg β1 and β3 subunits in diabetic rat models at the time of embryo implantation. Materials and Methods: Twenty-eight rats were randomly divided into 4 groups: control group, diabetic group, pioglitazone-treated group, and metformin-treated group. Real-time PCR was performed to determine changes in the expression of Itg α3, α4, αv, β1, and β3 genes in rat’s endometrium. Results: The expression of all Itg subunits increased significantly in diabetic rats’ endometrium compared with control group. Treatment with pioglitazone significantly reduced the level of Itg subunits gene expression compared with diabetic rats. While metformin had a different effect on α3 and α4 and elevated these two subunits gene expression. Conclusion: Diabetes mellitus significantly increased the expression of studied Itg subunits, therefore untreated diabetes could be potentially assumed as one of the preliminary elements in embryo implantation failure.

Background: Myeloperoxidase (MPO) is involved in the initiation, progression, and complications of atherosclerosis in diabetic patients. Objectives: In the current study, the impact of alpha-lipoic acid (LA), a natural antioxidant and a cofactor in the enzyme complexes on MPO, catalase (CAT) and glutathione peroxidase (GPx) activity, glutathione (GSH) and malondialdehyde (MDA) level, histopathology of kidney and expression of antioxidant enzymes, superoxide dismutase (SOD), GPx and CAT which are involved in the detoxification of reactive oxygen species (ROS), was evaluated in alloxan-induced diabetic rats. Materials and Methods: In this study, 30 male Rattus norvegicus rats randomly divided into three groups; control (C), non-treated diabetic (NTD), and LA-treated diabetics (LATD) was induced by alloxan monohydrate (100mg/kg; subcutaneous [SC]). Then treatment was performed with alphaLA (100 mg/kg intraperitoneal (i.p) daily to 6 weeks). Blood sample of animals collected to measure levels of MPO, CAT and GPx activity GSH and MDA. Kidney paraffin sections were prepared to estimate histological studies and to measure quantitative gene expression SOD, GPX and CAT in kidney. Results: Induction of diabetes led to a significant increase in MPO and MDA, reduced GSH level and GPx and CAT activities (P < 0.05). However, treatment with alpha-LA led to a significant elevation in GPx, CAT and GSH levels with a reduction in MPO activities and MDA levels (P < 0.05). Furthermore, the real-time reverse transcriptase-polymerase chain reaction (RT-PCR) analysis results showed increased expressions of GPx, CAT and SOD enzyme in the treatment group compared with the diabetic control group. Histopathological lesions such as increased glomerular volume and lymphocyte infiltration were attenuated in the alpha-LA treated group. Conclusions: Our findings indicated that alpha-LA supplementation is effective in preventing complications induced by oxidative stress and atherosclerosis in diabetic rats.

Abstract Background Blood glucose levels during pregnancy may reflect the severity of insulin secretory defects and/or insulin resistance during gestational diabetes mellitus (GDM) pregnancy. We hypothesized that suboptimal glycemic control in women with GDM could increase the risk of postpartum type 2 diabetes mellitus (T2DM) or prediabetes. Our objective was to evaluate the impact of plasma glucose levels throughout GDM pregnancy on the risk of postpartum T2DM or prediabetes. Methods The medical records of 706 women with GDM who underwent a postpartum 75-g, 2-hour oral glucose tolerance test at our institution between January 2011 and December 2018 were reviewed. These women were classified into 2 groups according to glycemic control during pregnancy: ≤ 1 occasion of either fasting glucose ≥ 95 mg/dL or 2-hour postprandial glucose ≥ 120 mg/dL was defined as optimal glycemic control or else was classified as suboptimal glycemic control. Rates of postpartum T2DM and prediabetes were compared between women with optimal (n = 505) and suboptimal (n = 201) glycemic control. Results The rates of postpartum T2DM and prediabetes were significantly higher in the suboptimal glycemic control group than in the optimal glycemic control group: 22.4% vs. 3.0%, P < 0.001 for T2DM and 45.3% vs. 23.5%, P < 0.001 for prediabetes. In a multivariate analysis, suboptimal glucose control during pregnancy was an independent risk factor for developing either postpartum T2DM or prediabetes. The adjusted odds ratios were 8.4 (95% confidence interval, 3.5–20.3) for T2DM and 3.9 (95% confidence interval, 2.5–6.1) for prediabetes. Conclusion Our findings suggest that blood glucose levels during GDM pregnancy have an impact on the risk of postpartum T2DM and prediabetes.

ABSTRACT Background: Chronic wounds in patients with Diabetes Mellitus often become incurable due to prolonged and excessive production of inflammatory cytokines. The use of probiotics modifies the intestinal microbiota and modulates inflammatory reactions. Aim: To evaluate the influence of perioperative supplementation with probiotics in the cutaneous healing process in diabetic rats. Methods: Forty-six rats were divided into four groups (C3, P3, C10, P10) according to the treatment (P=probiotic or C=control, both orally administered) and day of euthanasia, 3rd or 10th postoperative days. All rats were induced to Diabetes Mellitus 72 h before starting the experiment with alloxan. Supplementation was initiated five days before the incision and maintained until euthanasia. Scalpel incision was guided by a 2x2 cm mold and the wounds were left to heal per second-intention. The wounds were digitally measured. Collagen densitometry was done with Picrosirius Red staining. Histological parameters were analyzed by staining by H&E. Results: The contraction of the wound was faster in the P10 group which resulted in a smaller scar area (p=0.011). There was an increase in type I collagen deposition from the 3rd to the 10th postoperative day in the probiotic groups (p=0.016), which did not occur in the control group (p=0.487). The histological analysis showed a better degree of healing in the P10 group (p=0.005), with fewer polymorphonuclear (p<0.001) and more neovessels (p=0.001). Conclusions: Perioperative supplementation of probiotics stimulates skin wound healing in diabetic rats, possibly due to attenuation of the inflammatory response and increased neovascularization and type I collagen deposition.
