Butanol Extract

The strong n-butanol extract of oats (Avena sativa) seed was studied in streptozotocin-induced diabetic rats to improve lipid peroxidation and inhibitor standing. Four teams, NDM, and three diabetic teams were allocated thirty-two male rats. Diabetes  was caused by injection- streptozotocin (60 mg / kg B.w., i.p. Two hundred mg/deal of blood sugar rodents was used as a diabetic. Diabetes groups (G2, G3, and G4) were trained to extract n-butanol (60 mg / metric unit weight, B.w.) or twenty-one days of endocrine injection (4 IU / animal). Weight gain was reported on the 22nd day. Fluids were collected for knockout cells to judge glucose concentrations and subcellular of aminotransferase, aspartate transaminase, catalase, biochemical dismutase (SOD), glutathione - transferase, reductase, malondialdehyde and glutathione reductase (Gr) concentrations. Diabetes rat (G2) showed a significant increase in glucose. The weight gain increased in the ALT, SOD, CAT, GSH-transferase But there decreased GSH enzyme and old AST. Treatment of N-butanol extract from oats (G3) or endocrine (G4) varied between old glucose, weight gain and normalization of all supermolecule inhibitors. Finally, n- Butanol from oatmeal has a strong role in lowering hyperglycemia and as an antioxidant

Abstract Objectives Enteropathy is one of the most important complications of diabetes mellitus. The present study determined the possible effects of Tsukamurella inchonensis (Ti) on diabetes enteropathy on rat small intestine. Materials and methods A total of 40 rats were divided into four groups of 10. Diabetes was induced by streptozotocin. Oral administration of Ti at dose of 105 and 107 CFU/rat was performed in two groups continuously for 14 days. The third and fourth groups received normal saline as the diabetic and negative control groups, respectively. The blood and intestine tissue samples were taken on 21st day post treatment for biochemical and pathological evaluations. Results Significant differences were found in serum glucose, cholesterol and triglycerides values together with in CAT and SOD activities, MDA level and IL-6 concentration in both Ti treated groups in comparison with the diabetic rats. Moreover, there were severe pathological changes including degeneration of intestinal mucosa, mononuclear cell infiltration, decreasing number of goblet cells and villous length associated with increasing in villous thickness on the diabetic rats which markedly attenuated in both Ti recipient groups. Conclusion In conclusion, it seems that oral administration of Ti may improve intestinal damage in diabetic patients by modulation of intestinal antioxidant defense system.

AbstractObjective. The vast majority of type 1 diabetes leads to a higher prevalence of reproductive system’s impairments. Troxerutin has attracted much attention owing to its favorable properties, including antihyperglycemic, anti-inflammatory, and antiapoptotic effects. This investigation was proposed to evaluate whether pretreatment with troxerutin could prevent apoptosis-induced testicular disorders in prepubertal diabetic rats.Methods. Fifty prepubertal male Wistar rats were randomly allocated into five groups: control (C), troxerutin (TX), diabetic (D), diabetic+troxerutin (DTX), and diabetic+insulin (DI). Diabetes was induced by 55 mg/kg of streptozotocin applied intraperitoneally. In TX and DTX groups, 150 mg/kg troxerutin was administered by oral gavage. Diabetic rats in DI group received 2–4 U NPH insulin subcutaneously. Troxerutin and insulin treatments were begun immediately on the day of diabetes confirmation. After 30 days, the testicular lipid peroxidation and antioxidant activity, apoptosis process, and stereology as well as serum glucose and insulin levels were assessed.Results. The results showed that diabetes caused a significant increase in the blood glucose, the number of TUNEL positive cells and tubules, and the malondialdehyde level as well as a significant decrease in serum insulin level compared to controls. The stereological analysis also revealed various alterations in diabetic rats compared to controls. Troxerutin treatment improved these alterations compared to the diabetic group.Conclusion. Troxerutin-pretreatment may play an essential role in the management of the type-1 diabetes-induced testicular disorders by decreasing blood glucose and modulating apoptosis.

The World Health Organization (WHO) reported that alcohol consumption is a serious problem in adolescents. The aim of the study was to assess the influence of the time of exposure of various alcoholic beverages on body mass as well as on select parameters of liver antioxidant defense in adolescent Wistar rats. Thirty-day-old animals were divided into 12 groups (six animals in each): control and groups receiving various beverages containing 10% of alcohol (ethanol, red wine, beer), observed for two, four, and six weeks. The body weight gain and energy supply were analyzed for body mass assessment. The catalase (CAT), superoxide dismutase (SOD), glutathione peroxidase, transferase (GST), reductase activities, total antioxidant status, and glutathione level (GSH) were analyzed, for a liver antioxidant defense assessment. Group receiving red wine was characterized by the highest alcohol intake, lowest dietary intake, and highest total energy supply (p < 0.05). However, this did not influence body weight gain (p > 0.05). Reduced diet intake in groups receiving alcohol was counterbalanced by its energy value. Therefore, the energy supply was not lower than for the control (p > 0.05). Alcohol consumption and the experiment duration influenced CAT, SOD, and GST activities and GSH level. Alcohol consumption may influence hepatic antioxidant defense in adolescent male rats, but without influence on body weight gain.

Objective: Aerobic training and berberine chloride include antioxidant characteristics. In this study, aerobic training and berberine chloride intervention on the activity of antioxidant enzymes and lipid peroxidation of pancreatic tissue were investigated in type 1 diabetic male wistar rats. Materials and Methods: In the current study, 56 Wistar male rats were randomly assigned to seven different groups (n= 8), these groups include healthy control, diabetic control, Berberine-treated diabetes (15&30 mg/kg), aerobic training-treated diabetes, Diabetes treated with Berberine and aerobic training (15&30 mg/kg). The aerobic training schedule consisted of 6 weeks treadmills with a frequency of 5 sessions per week. The Berberine was also fed a specific dose every day and a half before training. The superoxide dismutase, glutathione peroxidase, catalase, and malondialdehyde were assessed using ELISA method. Results: The results showed that aerobic training, as well as the intervention of Aerobic Training and Berberine chloride, had a significant effect on the increase of antioxidant enzymes SOD and CAT in the pancreatic tissue groups (P-value< 0.05), but did not significantly affect the GPX level (P-value> 0.05). There was a significant decrease in MDA level in all treatment groups (P-value< 0.05). In diabetic groups that received both treatments at the same time, the MDA level more decreased (P-value< 0.0005). Conclusion: The aerobic training and berberine chloride concurrent intervention have a greater effect on the antioxidant enzymes in the pancreatic tissue of diabetic specimens. Therefore, it is recommended that aerobic training be done with berberine chloride.

Boldine is a natural alkaloid with anti-inflammatory and antioxidant effects. It reduces glycemia and decreases blood pressure in rats with type 1 diabetes. We have also studied whether boldine has anti-inflammatory and antioxidant effects in rats with type 2 diabetes and whether it can improve healing of their skin wounds, a serious comorbidity of type 2 diabetes. This work also compares lean and obese Zucker diabetic rats, including a comparison of both sexes. After skin excisions, the wounded animals received granules containing boldine ad libitum. The weights of rats, amount of consumed food and wound size were measured regularly. Scar and internal organs were removed and analyzed. Further, the tensile strength of the scar was tested and hydroxyproline content (a marker of collagen) measured. We have not confirmed previously published positive effects of boldine, but we observed important differences between gender and between genotypes. Male rats had higher body weight, liver, kidney and spleen than female rats. Furthermore, their wounds took longer to heal with bigger scar areas.

Abstract Objectives This experimentally-controlled designed nutritional study, aimed to determine the effects of Zn-supplemented diet on glycemic profile, tolerance and control, body weight and pancreatic Islet β-cells in diabetic male rats. Methods Twenty four male Wistar rats each weighing ≥200 g were randomly categorized into three experimental groups (n = 8, each): Normal control (NC) fed with standard rat feed; Diabetic control (DC) fed with control diet and Diabetic (DZ) on test (zinc-supplemented) diet. Diabetes was inducted with freshly prepared alloxan monohydrate solution (150 mg/dL, intraperitoneally). Rats were fed for a period of eight weeks according to the experimental design with water ad libitum while their weights were measured twice weekly and recorded. Fasting blood sugar (FBS) levels were measured twice weekly while oral glucose tolerance test (OGTT) was conducted to construct the glycemic response curves. Animals were sacrificed at the end of eight week to extract pancreas for immunocytochemical and histomorphometric analyses. Microsoft Excel and statistical program SPSS version 22.0 were used to analyse data while P values <0.05 were considered significant. Results At the end of eight week study, Zn-supplemented diet caused significant (P < 0.05) reductions in mean body weight gain (28.5%) and FBS (31.5%) levels, stimulated islet β-cells regeneration and improved glycemic tolerance and profile in DZ rats compared with the diabetic control rats. Conclusions In conclusion, zinc-supplemented diet impacts beneficial antidiabetic effect in diabetic rats via stimulation of pancreatic islet β-cells regeneration, reduction of body weight gain and lowering of blood glucose level.

Pressor Reflex

Previous studies have shown that diabetic peripheral neuropathy affects both unmyelinated and myelinated afferents, similar to those evoking the exercise pressor reflex. However, the effect of type 1 diabetes (T1DM) on this reflex is not known. We examined, in decerebrate male and female T1DM [streptozotocin (STZ)] and healthy control (CTL) rats, pressor and cardioaccelerator responses to isometric contraction of the hindlimb muscles during the early and late stages of the disease. STZ (50 mg/kg) was injected to induce diabetes, and experiments were conducted at 1, 3, and 6 wk after injection. On the day of the experiment, we statically contracted the hindlimb muscles by stimulating the sciatic nerve and measured changes in mean arterial pressure and heart rate. We found that the pressor but not cardioaccelerator response was exaggerated in STZ rats at 1 wk (STZ: 21 ± 3 mmHg, n = 10, and CTL: 14 ± 2 mmHg, n = 10, P < 0.05) and at 3 wk (STZ: 26 ± 5 mmHg, n = 10, and CTL: 17 ± 3 mmHg, n = 11, P < 0.05) after injection. However, at 6 wk, and only in male rats, both the pressor (STZ: 13 ± 3 mmHg, n = 12, and CTL: 17 ± 3 mmHg, n = 13, P < 0.05) and cardioaccelerator responses (STZ: 7 ± 3 beats/min, n = 12, and CTL: 10 ± 3 beats/min, n = 13, P < 0.05) to contraction were significantly attenuated in STZ rats compared with CTL rats. These data indicate that T1DM exaggerates the exercise pressor reflex during the early stages of the disease in both male and female rats. Conversely, T1DM attenuates this reflex in the late stage of the disease in male but not female rats. NEW & NOTEWORTHY This is the first study to provide evidence that the pressor and cardioaccelerator responses to skeletal muscle contraction vary depending on the duration of type 1 diabetes.

Background and aims: The cardiac angiogenesis is one of the complications of diabetes. The oxidative stress occurs when there is an imbalance between the production of free radicals and antioxidant defense of the body. In diabetes mellitus, hyperglycemia induces increased oxidative stress through biological processes. Diabetes is also associated with reduced antioxidant defense by reducing glutathione, catalase, and superoxide dismutase. Rosa damascena Mill has antioxidant properties. This study aimed to investigate the effects of hydroalcoholic extract of R. damascena Mill on cardiac angiogenesis in diabetic rats. Methods: In this experimental study carried out in 2016, a total of 48 adult male Wistar rats (190-200 g) were randomly divided into 8 groups (n=6) including control, extracts (200, 400, and 1000 mg/kg), diabetic, and diabetic plus extracts (200, 400, and 1000 mg/kg). Diabetes was induced by intraperitoneal (i.p.) injection of streptozotocin (STZ) (50 mg/kg) and the rats were gavaged with different doses of extract for 30 days. At the end of the treatment, serum levels of vascular endothelial growth factor (VEGF) were determined by enzymelinked immunosorbent assay and the rat hearts were removed for immunohistochemistry study. Results: The treatment with hydroalcoholic extract of R. damascene Mill had no significant effect on cardiac capillary density [F (7, 40)=0.5, P>0.05] and the serum levels of VEGF [F (7, 40)=0.406, P>0.05]. However, there was no significant difference in blood glucose level in extract groups compared to control rats as well as diabetic plus extract groups compared to diabetic rats [F (7,40)=0.787, P>0.05]. Conclusion: According to our results, the hydroalcoholic extract of R. damascene Mill had no effect on cardiac angiogenesis in the normal and diabetic subjects. These findings were probably due to the insufficient amounts of effective ingredients, especially flavonoids, in this plant, or the duration of extract administration.

Objectives Impaired angiogenesis in sciatic nerve is a major complication of diabetic neuropathy. Protein kinase B (AKT) and extracellular signal regulated kinase (ERK) signaling pathways play critical roles during capillary-like network formation in the angiogenesis process. Methods Twenty-four adult male Wistar rats (weight: 250–300 g) were used in the research. The rats were randomly divided into four groups (n = 6): (1) diabetic (Dia), (2) diabetic + castration (Dia-Cas), (3) diabetic + exercise (Dia-E), and (4) diabetic + castration + exercise (Dia-Cas-E). Type 1 diabetes (T1D) was induced with streptozotocin (50 mg/kg). After 6 weeks, sciatic nerve was separated and used for histological evaluation and determination of phosphorylated AKT (P-AKT) and phosphorylated ERK (P-ERK) levels by ELISA method. Results Glucose levels decreased in the Dia-E group compared to the Dia-Cas group (p < 0.01). In addition, our finding shows that exercise in the Dia-Cas group diminished blood glucose levels compared to the Dia-Cas group but this effect of exercise was not significant. Voluntary exercise in the diabetic castrated group decreased P-AKT protein and increased P-ERK 1/2 protein levels in the sciatic tissue compared to the diabetes group significantly (p < 0.05). Histopathological findings showed that Dia-Cas group with 6-week exercise training significantly raised the number of microvascular density in the sciatic tissue of diabetic rats compared to the diabetic group (p < 0.05). Conclusions Voluntary exercise in diabetic rats increases angiogenesis in the sciatic nerve. The possible mechanism is the increase of P-ERK 1/2 but not P-AKT levels in the sciatic nerve of T1D rats.
