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.

Topicality. In Ukraine, the number of patients with diabetes is growing rapidly, it ranks the 4th in the structure of diseases of the endocrine system, and it is one of the main causes of incapacitation and disability among the population and takes the second place by the number of deaths. Polyphenolic extracts from leaves of the heather (Ericaceae) family, in particular blueberries, cranberries and bearberry, in the previous studies demonstrated the presence of antioxidant, hypoglycemic and lipotropic properties. However, the pharmacological activity of extracts from cranberry leaves has not been sufficiently studied. Aim. To study the effect of polyphenolic extracts from cranberry leaves on the processes of LPO and the state of the antioxidant defense in the liver and serum in rats with the experimental insulin resistance. Materials and methods. The study was performed on white outbred male rats weighing 180 ± 15 g, kept in the vivarium of the NUPh. Insulin resistance was induced by keeping animals on a high fructose diet for 6 weeks according to the recommendations. The extracts were administered intragastrically in the dose of 200 μg/100 g of the body weight from the fourth week of the experiment for 14 days. The POL activity was assessed by the level of TBA reactants, diene conjugates and conjugated trienes in the liver and serum. The state of the antioxidant defense was assessed by the level of reduced glutathione, as well as the activity of catalase and superoxide dismutase. Indicators were determined by the spectrophotometric method. Results and discussion. The development of the experimental resistance was accompanied by an increase in LPS activity in the liver and serum of rats. In the serum of animals with IR the content of primary products of LPO increased in 1.75 times, the content of triene conjugates in 1.7 times, respectively, while the content of TBA reactants in 1.61 times. The introduction of the polyphenolic concentrate from cranberry leaves was accompanied by a sharp decrease in the products of lipid peroxidation both in the eserum and liver to almost ascending levels. There was normalization of the activity of enzymes of the first line of the antioxidant defense compared to animals with insulin resistance due to the presence of plant flavonoids in the extract. Conclusions. Thus, the data obtained indicate that the polyphenolic extract from cranberry leaves exhibits antioxidant properties in the liver and serum of rats with the experimental insulin resistance. The polyphenolic extract also restored the antioxidant defense of cells and the body as a whole. The data obtained indicate the need for further research to create a new herbal medicine for use in the treatment of insulin resistance and diabetes.

Objective: The production of reactive oxygen species in exercise causes oxidative stress which disturbs the balance of oxidants and antioxidants, causing destructive effects on cells. The present study aims to investigate the effect of three types of massage (Swedish, Russian, Thai) on serum levels of Malondialdehyde (MDA), Glutathione Peroxidase (GPX) and Superoxide Dismutase (SOD) following one session of exhaustive exercise. Methods: This quasi-experimental study was conducted on 48 female futsal players aged 17-22 years in Zahedan, Iran who were selected using a purposive sampling method, and randomly divided into four groups of Swedish massage (Long strokes with pressing and tapping using hands), Russian massage (Medium to high pressure), Thai massage (Pressure to certain parts of the body) and Control. The exercise program was based on Bruce protocol. Serum levels of MDA, GPX and SOD were measured by before and immediately after exercise and after massage. Data analysis was performed using repeated measures ANOVA, considering a significance level of P≤0.05. Results: In all three types of massage, there was a significant decrease in serum level of MDA (0.22±0.08), and a significant increase in GPX (1.84±0.46) and SOD (10.02±2.86) levels after exhaustive (P=0.001). No significant difference was observed in the control group. Conclusion: It seems that Russian, Thai, and Swedish types of massage can affect the serum levels of the MDA (as an oxidative stress marker) and the antioxidant enzymes of GPX and SOD during the post-exercise recovery period.

Background: The present study was performed to investigate the protective effects of propofol against cisplatin-induced pulmonary toxicity in rats. Methods: A total of 20 male Wistar rats weighing 180-250 g were divided into four groups of control, the cisplatin-intoxicated group intraperitoneally (IP) injected with cisplatin (7 mg/kg/d for a week), the propofol group (10 mg/kg/d, IP), and the protected group receiving propofol (10 mg/kg/d, IP) poisoned by cisplatin. Then, the biomarkers of total antioxidant capacity (TAC), catalase (CAT) activity, and lipid peroxidation (LPO) were measured in homogeneous lung tissues. Results: The data revealed the evidence of oxidative stress in the lung tissue of cisplatin-intoxicated rats as indicated by an increase in the level of LPO compared with propofol and protected groups (P<0.05). Moreover, TAC decreased in the cisplatin group while it increased in the propofol group compared to cisplatin and protected groups (P<0.05). No significant difference was observed between the groups regarding CAT (P>0.05). Protection with propofol ameliorated the oxidative stress induced by cisplatin in the lung tissue because of the reduction of LPO. Conclusion: According to these results, it seems that propofol provides a remarkable protection against cisplatin-induced oxidative pulmonary damage mediated by its antioxidant properties.

Background: Oxidative stress plays an important role in the development of diabetic complications. Objective: This study evaluated the impact of pre- and post-treatment with Lactobacillus acidophilus ATCC 4356 on the oxidant and anti-oxidant factors of testis and epididymis in streptozotocin-induced diabetic rats. Materials and Methods: Thirty male Wistar rats (10 wk old) weighing 220-230 g. were divided into five groups (n = 6/ each): 1- normal group, 2- normal lactobacillus group, 3- diabetic group, 4- diabetic + lactobacillus before (DLB) group, and 5- diabetic + lactobacillus after (DLA) group. The normal and diabetic groups received daily 1 mL normal saline for 6 wk. Normal lactobacillus group received daily L. acidophilus for 6 wk. Group DLB received daily L. acidophilus for 2 wk before diabetes and for 4 wk after diabetes. Group DLA received daily 1 mL normal saline for 2 wk before diabetes and L. acidophilus for 4 wk after diabetes. The dose of L. acidophilus was 1 × 109 CFU/mL. Results: The administration of L. acidophilus worsened blood glucose level and reduced the levels of Malondialdehyde (p = ≤ 0.0001) and Hydrogen peroxide (p ≤ 0.0001) and, Catalase and Glutathione peroxidase activity increased in the testis. In epididymis, Glutathione peroxidase and Catalase (p = 0.013) activity increased and Hydrogen peroxide concentration reduced, while Malondialdehyde concentration did not show any changes compared to the diabetic rats. Also, there was no significant difference between DLB and DLA groups, in these markers. Conclusion: Data obtained suggests that L. acidophilus has anti-oxidant effects on the testis and sometime in the epididymis in diabetic rats.

Abstract Background Diabetes, a global cause of mortality in developing countries is a chronic disorder affecting the metabolism of macromolecules and has been attributed to the defective production and action of insulin characterized by persistent hyperglycemic properties. This global disorder harms organs of the body such as the liver, kidney and spleen. Medicinal plants such as Hunteria umbellate have been shown to possess hypoglycemic, antioxidative and anti-diabetic properties owing to the high concentration of active phytochemical constituents like flavonoids and alkaloids. The present study seeks to evaluate the hypoglycemic activities of ethanolic seed extract of Hunteria umbellate on streptozotocin-induced diabetes rats. Methods Thirty (30) female experimental rats were randomly divided into five groups with six rats per group and were administered streptozotocin (STZ) and Hunteria umbellate as follows. Group 1 served as control and was given only distilled water, group 2 rats were administered 60 mg/kg STZ; Group 3 was administered 60 mg/kg STZ and 100 mg/kg metformin; group 4 rats were administered 60 mg/kg STZ and 800 mg/kg Hunteria umbellate, group 5 rats 60 mg/kg STZ and 400 mg/kg Hunteria umbellate. The fasting blood glucose level of each rat was measured before sacrifice. Rats were then sacrificed 24 h after the last dose of treatment. Results The results showed that Hunteria umbellate significantly reversed STZ-induced increase in fasting blood glucose and increase in body and organs weight of rats. Hunteria umbellate significantly reversed STZ-induced decrease in antioxidant enzyme in liver, kidney and spleen of rats. Hunteria umbellate significantly reversed STZ-induced increase in oxidative stress markers in liver, kidney and spleen of rats. Conclusion Collectively, our results provide convincing information that inhibition of oxidative stress and regulation of blood glucose level are major mechanisms through which Hunteria umbellate protects against streptozotocin-induced diabketes rats.

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.

Hyperglycemia-induced oxidative stress plays important roles in the development of non-alcoholic fatty liver disease (NAFLD), which is a common complication in diabetic patients. The Nrf2-Keap1 pathway is important for cell antioxidant protection, while its role in exogenous antioxidant mediated protection against NAFLD is unclear. We thus, postulated that antioxidant treatment with allopurinol (ALP) may attenuate diabetic liver injury and explored the underlying mechanisms. Control (C) and streptozotocin (STZ)-induced diabetes rats (D) were untreated or treated with ALP for 4 weeks starting at 1 week after diabetes induction. Serum levels of alanine aminotransferase (ALT) and aspartate transaminase (AST), production of lipid peroxidation product malondialdehyde (MDA), and serum superoxide dismutase (SOD) were detected. Liver protein expressions of cleaved-caspase 3, IL-1β, nuclear factor-erythroid-2-related factor-2 (Nrf2), heme oxygenase-1 (HO-1), P62, Kelch-like ECH-associated protein 1 (Keap1), and LC3 were analyzed. In vitro, cultured rat normal hepatocytes BRL-3A were grouped to normal glucose (5.5 mM, NG) or high glucose (25 mM, HG) and treated with or without allopurinol (100 µM) for 48 h. Rats in the D group demonstrated liver injury evidenced as increased serum levels of ALT and AST. Diabetes increased apoptotic cell death, enhanced liver protein expressions of cleaved-caspase 3 and IL-1β with concomitantly increased production of MDA while serum SOD content was significantly reduced (all P < 0.05 vs C). In the meantime, protein levels of Nrf2, HO-1, and P62 were reduced while Keap1 and LC3 were increased in the untreated D group as compared to control ( P < 0.05 vs C). And all the above alterations were significantly attenuated by ALP. Similar to our findings obtained from in vivo study, we got the same results in in vitro experiments. It is concluded that ALP activates the Nrf2/p62 pathway to ameliorate oxidative stress and liver injury in diabetic rats.
