Objective: The strong antioxidant activity of <i>Commiphora mukul</i> prompted us to conduct the present study to explore whether treatment with <i>C. mukul</i> extract (CME) would have any protective influence on sperm parameters, testosterone levels, and plasma glucose levels in streptozotocin (STZ)-induced diabetic rats.Methods: Male Wistar rats were randomly divided into four groups: control, control animals treated with CME, diabetic animals, and diabetic animals treated with CME. CME extract (300 mg/kg) was administered for 60 days by daily gavage. Diabetes was induced by an intraperitoneal injection of 50 mg/kg STZ. The epididymal sperm count, weight, motility, morphology, viability, and serum testosterone and glucose levels were determined.Results: In the diabetic animals, CME decreased blood glucose levels (<i>p</i><0.05), increased the total sperm count (<i>p</i><0.05), and decreased the proportion of sperm with abnormal morphology (<i>p</i><0.05). Diabetes reduced sperm motility (<i>p</i><0.001), and CME supplementation partially reversed this effect of diabetes (<i>p</i>=0.003). Furthermore, in diabetic animals, CME decreased the proportion of immotile sperm (<i>p</i><0.001). In rats, diabetes caused a significant decrease (<i>p</i><0.05) in serum testosterone levels (F[3, 28]=3.283, <i>p</i>=0.035), but treatment of diabetic animals with CME increased serum testosterone levels.Conclusion: The present study demonstrated that C. mukul possesses proandrogenic activity and exerts a beneficial effect on sperm parameters in diabetic rats.

Diabetes mellitus (DM) constitutes one of the public health problems today. It is characterized by hyperglycemia through a defect in the β-cells function and/or decreased insulin sensitivity. Apocynin has been tasted acting directly as an NADPH oxidase inhibitor and reactive oxygen species (ROS) scavenger, exhibiting beneficial effects against diabetic complications. Hence, the present study’s goal was to dissect the possible mechanisms by which apocynin could mediate its cardioprotective effect against DM-induced oxidative stress. Male Wistar rats were assigned into 4 groups: Control (C), control + apocynin (C+A), diabetes (D), diabetes + apocynin (D+A). DM was induced with streptozotocin. Apocynin treatment (3 mg/kg/day) was applied for 5 weeks. Treatment significantly decreased blood glucose levels and insulin resistance in diabetic rats. In cardiac tissue, ROS levels were higher, and catalase enzyme activity was reduced in the D group compared to the C group; the apocynin treatment significantly attenuated these responses. In heart mitochondria, Complexes I and II of the electron transport chain (ETC) were significantly enhanced in the D+A group. Total glutathione, the level of reduced glutathione (GSH) and the GSH/ oxidized glutathione (GSSG) ratio were increased in the D+A group. Superoxide dismutase (SOD) and the glutathione peroxidase (GSH-Px) activities were without change. Apocynin enhances glucose uptake and insulin sensitivity, preserving the antioxidant defense and mitochondrial function.

Биохимическим маркером сахарного диабета и его тяжелейших осложнений является гипергликемия. В качестве новых средств растительного происхождения, обладающих гипогликемической активностью, в настоящее время рассматривают пектины. Цель исследования - оценка функциональных свойств пектина, полученного из тыквенного жома с использованием кавитационно-мембранной технологии. Методика. Использована модель аллоксан-индуцированного сахарного диабета. Эксперимент проводили на крысах - самцах Wistar (инъекции раствора аллоксана моногидрата из расчета 43 мг/кг массы). Развитие диабета подтверждалось уровнем глюкозы (>10 мМ) в периферической крови. Для тестирования гипогликемической активности тыквенного пектина опытной группе крыс внутрижелудочно с помощью металлического зонда (Kent Scientific, США) вводили 5% раствор пектина в дистиллированной воде в дозировке 25 мг/100 г живой массы в сутки в течение 3 нед. Пектин, полученный из тыквенного жома с использованием кавитационно-мембранной технологии, имел следующие характеристики: диапазон молекулярных масс 90-120 кДа, содержание полигалактуроновой кислоты в среднем около 75% и степень этерификации 72%, что позволяет его отнести к пектинам с высокой степенью этерификации. Результаты. У животных 2-й и 3-й групп по истечении 1-3 нед. после воспроизведении диабета выявлена гипергликемия - уровень глюкозы в цельной крови был значимо выше. Статистический анализ «size effect» показал, что в начале эксперимента различия в уровне глюкозы в крови животных 2-й и 3-й групп незначительны (d = 0,39). Через 3 нед. они достигают среднего эффекта (d = 0,50). Этот факт можно расценивать как тенденцию к нормализации уровня глюкозы на фоне приема тыквенного пектина. Значимое снижение сывороточной концентрации фруктозамина в опытной группе показало гипогликемический эффект тыквенного пектина. Введение пектина животным также снижало содержание холестерина в печени и сывороточную концентрацию неэстерефицированных жирных кислот (НЭЖК), демонстрируя его гипохолестеринемические свойства. Антиоксидантные свойства пектина проявлялись нормализацией уровня ТБК-реактивных продуктов в сыворотке крови опытной группы животных. Заключение. Подтверждены гипогликемический, гипохолестеринемический и антиоксидантный эффекты пектина из тыквы (Cucurbita maxima D.) при аллоксан-индуцированном сахарном диабете. Hyperglycemia is a biochemically defined initial symptom of diabetes and its serious complications (atherosclerosis, retinopathy, kidney damage). Pectins are currently considered as novel plant-produced hypoglycemic agents. The aim of this study was to evaluate bio-functional properties of pumpkin pectin obtained from pumpkin pulp using cavitation-membrane technologies in a model of alloxan-induced diabetes. Methods. Male Wistar rats were used in the experiments. Diabetes was modeled by injections of 4.3% alloxan monohydrate solution. The development of diabetes was confirmed by glucose concentration in peripheral blood (glucose levels of >10 mM in whole blood was consistent with diabetes). To test the hypoglycemic activity of pumpkin pectin, a 5% pectin solution in distilled water was administered to rats of the experimental group (25 mg/100 g body weight, daily, for three weeks) through a metal gastric tube (Kent Scientific, USA). Results. A significant decrease of fructosamine concentration observed in the experimental group indicated a hypoglycemic effect of pectin. Administration of pectin to animals also reduced concentrations of cholesterol in liver and non-esterified fatty acids (NEFAs) in blood serum, which demonstrated cholesterol-lowering properties of pectin. Antioxidant properties of pectin provided a decrease in serum TBA-reactive products to the level observed in non-diabetic rats, in pectin-treated diabetic animals compared to the untreated diabetic group.

This study aimed to analyze the effect of red rice enriched-kappa-carrageenan and anthocyanin extracts on blood antioxidant profile in diabetic rats. Variables analyzed in this research were blood glucose, malondialdehyde (MDA) level, and plasma antioxidant by Ferric Reducing Ability of Plasma (FRAP) method. This study was conducted in vivo on male Wistar rats aged 2.5 months using completely randomized design. Rats divided into 6 groups based on types of feed, standard feed (normal and DM), red rice (BM), red rice enriched kappa-carrageenan (BMK), red rice enriched extracts of anthocyanin (BMA) and red rice enriched with kappa-carrageenan and extract anthocyanin (BMKA). Experiments were carried out for 6 weeks. Rats feed with red rice showed decreased in blood glucose levels from 234.26 to 84.78 mg/dL (p = 0.000), MDA diabetic group compared to BMKA 2.175 and 0.530 μmol/L (p = 0.000) respectively, and the rate of FRAP in DM and BMKA 69 and 216 nmol/mL (p = 0.000) respectively. This study showed that red rice enriched with kappa-carrageenan and anthocyanin extract was able to decrease blood glucose levels and increase plasma antioxidant of diabetic rats which characterized by decreased MDA value and increased FRAP value. ABSTRAKPenelitian ini bertujuan mengkaji pengaruh pemberian beras merah yang diperkaya kappa-karagenan dan ekstrak antosianin terhadap profil antioksidan darah pada tikus Diabetes Melitus (DM).

Background. Therapeutic strategies based on herbal plants and diets containing sufficient amounts of antioxidants and essential vitamins are very important factors in treating reproduction and male infertility worldwide. Thus, the aim of this study was to investigate the potential effects of Kaempferia parviflora (KP) on the role of some microRNAs in treated and nontreated infertile rats. In addition, the correlation of expressed microRNAs with sperm count, sperm motility, and sperm viability was identified. The probable use of these microRNAs as a diagnostic marker for predicting the clinical response of infertility to the treatment with KP was also achieved. Methods. In the present study, the potential effects of Kaempferia parviflora (KP) at different doses (140, 280, and 420 mg/kg) for six weeks on male rats with subinfertility were explored. In addition, the effect of KP on the expression of circulating microRNAs and its correlation with the parameters of sexual infertility was identified by performing both in vitro and in vivo assays. In vitro antioxidant activity, sperm functional analysis, serum testosterone, and expression of circulating microRNAs were conducted using colorimetric, ELISA, and real-time RT-PCR analysis, respectively. Results. Kaempferia parviflora (KP) at nontoxic doses of 140–420 mg/kg/day for six weeks significantly improved serum testosterone and epididymal sperm parameters (sperm count, motility, and sperm viability), increased testicular weight, and provided a reduction in the percentage of abnormal spermatozoon in infertile male rats. The expression of miR-328 and miR-19b significantly decreased, and miR-34 significantly increased in infertile rats treated with KP compared to infertile nontreated rats. After six weeks of KP therapy, the change in the expression levels of miRNAs was correlated positively with higher levels of serum testosterone and the measures of epididymal sperm parameters. The respective area under the receiver operating characteristic curve (AUC-ROC) was applied to predict the potential use of miR-328, miR-19b, and miR-34 in the diagnosis of male infertility in treated and nontreated infertile male rats. The data showed that AUC cutoff values of 0.91 for miR-328, 0.89 for miR-19b, and 0.86 for miR34 were the best estimated values for the clinical diagnosis of male rats with infertility. In rats treated with KP for six weeks, AUC cutoff values of 0.76 for miR-328, 0.79 for miR-19b, and 0.81 for miR-34 were the best cutoff values reported for the clinical response of infertility to KP therapy after six weeks. Conclusions. In this study, the improvement of male infertility might proceed via antioxidant and antiapoptotic pathways, which significantly improve spermatogenesis and aphrodisiac properties of males. In addition, the expression of miRNAs, miR-328, miR-34, and miR-19b, in KP-treated and nontreated infertile rats significantly correlated with increased serum testosterone levels and epididymal sperm parameters as well. MicroRNAs, miR-328, miR-34, and miR-19b, might be related to oxidative and apoptotic pathways that proceeded in spermatogenesis. Thus, the use of miRNAs could have a role as diagnostic, therapeutic, and predictive markers for assessing the clinical response of Kaempferia parviflora treatment for six weeks. This may have potential applications in the therapeutic strategies based on herbal plants for male infertility. However, in subsequent studies, the genetic regulatory mechanisms of the expressed miRNAs should be fully characterized.

Testicular atrophy and reduced epididymal sperm count are known to occur after i.p. administration of high doses of hexavalent chromium to rats. The effect of 0.5 mg kg -1 hexavalent chromium injected i.p. 5 d a week for 8 weeks was investigated in male Wistar rats. A significant reduction in epididymal sperm motility was found at the end of the exposure period. The reduction was reversed after an unexposed period of a further 8 weeks. In addition, a decrease in serum testosterone and an increase in FSH were found at the end of the exposure period. The results indicate that a number of mechanisms may be involved in the deleterious effects of chromate on male fecundity.

Background: To evaluate the effect of tamsulosin on blood glucose levels in euglycaemic rats and to investigate the effect of glibenclamide, tamsulosin and their combination on alloxan induced diabetic rats.Methods: Albino male wistar rats were randomly assigned into 6 groups (2 euglycaemic and 4 alloxan induced diabetic rats groups). In Euglycaemic rats either normal saline (0.5ml P.O) or tamsulosin (0.072mg/kg P.O) were given and blood glucose levels was estimated at 0 hr, 30min, 1hr, 2hr, 4hr on day 1 and at 0hr and 1hr on day 3 and day 7. Four groups of diabetic rats were given normal saline (0.5ml P.O), glibenclamide (5mg/kg P.O), tamsulosin (0.072mg/kg P.O), combination of glibenclamide and tamsulosin respectively and blood glucose levels were estimated on day 1, 3 and 7. Repeated measures ANOVA or paired ‘t ‘test were used for within group comparison and one way ANOVA or unpaired ‘t’ test were used for between group comparison.Results: In euglycaemic rats tamsulosin caused significant rise in blood glucose levels at 1 hr on all days and in diabetic rats tamsulosin itself did not cause any significant alteration in blood glucose levels. However, its combination with glibenclamide delayed the onset of hypoglycemic effect of glibenclamide & also reduced its hypoglycemic effect.Conclusions: Tamsulosin significantly increase blood glucose level in euglycaemic rats and it interact with Glibenclamide to reduce its hypoglycemic activity in diabetic rats.

AbstractObjective.The aim of this study was to assess whether microRNA-146a and its adapter proteins TNF receptor associated factor6 (TRAF6) and interleukin-1 receptor-associated kinase-1 (IRAK1) may be changed in the kidney of streptozotocin-induced diabetic rats, following regular moderate exercise.Methods.Forty adult male Wistar rats were allocated randomly into four groups (n=10), including sedentary control (SC), sedentary diabetic (SD), healthy sixty-day exercise (H60E), and diabetic sixty-day exercise (D60E) groups. Diabetes was induced by an intraperitoneal injection of 60 mg/kg streptozotocin. After 48 h, blood glucose levels >250 mg/dl was included to diabetic rats. After 2 days of diabetes induction, the exercise protocol began. Animals were exposed to 5 days of consecutive treadmill exercise for 60 min/day with the 22 m/min speed for 60 days. The kidneys of the rats were removed and microRNA was extracted from them using the miRCURYTM RNA isolation kit.Results.In diabetic rats, statistical analysis revealed a significant decrease in miR-146a expression, non-significant decrease in IRAK1 mRNA expression, and non-significant increase in TRAF6 and NF-kB mRNA expression compared to the SC group. Exercise led to a non-significant increase in the expression of miR-146a and NF-kB mRNA in the kidneys of the diabetic group as compared to the SD group, significant increase in TRAF6 and IRAK1 mRNA expression compared to the H60E group, and significant increase in TRAF6 mRNA expression compared to the SD group.Conclusion.The present data indicate that exercise might be able to help in the prevention in the diabetic nephropathy development.

Abstract. Objective: This study aimed to evaluate the effect of maternal consumption of flaxseed flour and oil on serum concentrations of glucose, insulin, and thyroid hormones of the adult female offspring of diabetic rats. Methods: Wistar rats were induced to diabetes by a high-fat diet (60%) and streptozotocin (35 mg/kg). Rats were mated and once pregnancy was confirmed, were divided into the following groups: Control Group (CG): casein-based diet; High-fat Group (HG): high-fat diet (49%); High-fat Flaxseed Group (HFG): high-fat diet supplemented with 25% flaxseed flour; High-fat Flaxseed Oil group (HOG): high-fat diet, where soya oil was replaced with flaxseed oil. After weaning, female pups (n = 6) from each group were separated, received a commercial rat diet and were sacrificed after 180 days. Serum insulin concentrations were determined by ELISA, the levels of triiodothyronine (T3), thyroxine (T4) and thyroid-stimulating hormone (TSH) were determined by chemiluminescence. Results: There was a significant reduction in body weight at weaning in HG (−31%), HFG (−33%) and HOG (44%) compared to CG (p = 0.002), which became similar by the end of 180 days. Blood glucose levels were reduced in HFG (−10%, p = 0.044) when compared to CG, and there was no significant difference between groups in relation to insulin, T3, T4, and TSH after 180 days. Conclusions: Maternal severe hyperglycemia during pregnancy and lactation resulted in a microsomal offspring. Maternal consumption of flaxseed reduces blood glucose levels in adult offspring without significant effects on insulin levels and thyroid hormones.

Aims: Arganimide A (4,4-dihydroxy-3,3-imino-di-benzoic acid) is a compound belonging to a family of aminophenolics found in fruit of Argania spinosa. The purpose of this study was to investigate the glucose and lipid lowering activity of Arganimide A (ARG A). Methods: The effect of a single dose and daily oral administration of Arganimide A (ARG A) on blood glucose levels and plasma lipid profile was tested in normal and streptozotocin (STZ) diabetic rats at a dose of 2 mg/kg body weight. Results: Single oral administration of ARG A reduced blood glucose levels from 26.50±0.61 mmol/L to 14.27±0.73 mmol/L (p<0.0001) six hours after administration in STZ diabetic rats. Furthermore, blood glucose levels were decreased from 5.35±0.30 mmol/L to 3.57±0.17 mmol/L (p<0.0001) and from 26.50±0.61 mmol/L to 3.67±0.29 mmol/L (p<0.0001) in normal and STZ diabetic rats, respectively, after seven days of treatment. Moreover, no significant changes in body weight in normal and STZ rats were shown. According to the lipid profile, the plasma triglycerides levels were decreased significantly in diabetic rats after seven days of ARG treatment (p<0.05). Moreover, seven days of ARG A treatment decreased significantly the plasma cholesterol concentrations (p<0.001). Conclusion: ARG A possesses glucose and lipid-lowering activity in diabetic rats and this natural compound may be beneficial in the treatment of diabetes.

Objective: The aim of this work was to evaluate the antihyperglycemic activity of aerial parts aqueous extract (A.P.A.E) of Mentha pulegium (M. pulegium) on blood glucose levels in normal and streptozotocin(STZ)-induced diabetic rat. The glucose tolerance was evaluated in normal rats. Moreover, the histological sections and morphometric analysis at the liver and pancreas have been carried out in this investigation both in normal and STZ-diabetic rats. Methods: The effect of A.P.A.E of M. pulegium (20 mg/kg) on blood glucose levels was investigated in normal and diabetic rats (n=6). Histopathological changes in liver and pancreas were examined under phase contrast microscope and a preliminary screening for various bioactive constituents was realized according to standard methods. Key Findings: Both single and repeated oral administration of A.P.A.E (20 mg/kg) caused a significant reduction in blood glucose levels in STZ-diabetic rats (p<0.0001). The morphometric analysis and histological sections realized in pancreas and liver have showed the beneficial effect of the A.P.A.E in cellular population. According to oral glucose tolerance test (OGTT), the aqueous extract has revealed an improvement of glucose tolerance in normal rat. Furthermore, the preliminary phytochemical screening of A.P.A.E of M. pulegium has demonstrated the presence of various metabolite compounds including polyphenols, flavonoids, terpenoids tannins, cyanidins, sesquiterpenes, and glycosides. Conclusion: We conclude that the A.P.A.E of M. pulegium (20 mg/kg) exhibits a potent antihyperglycemic activity in STZ diabetic rats.
