Supplementation of Thymoquinone and Carob Together in the Experimental Rat Asthma Model: Oxidative Effect on the Liver Tissue

Asthma, an important public health problem, is a common, potentially serious, medical condition in children, adults and pregnant women. The aim of this study is to investigate the effects of the combined use of thymoquinone and carob on liver tissue oxidative events, following the experimental asthma model. 18 male albino wistar rats were divided into 3 groups as: the control group, the experimental asthma group and treated group (A+TQ+C). In the asthmatic groups, ovalbumin and alum were given intraperitoneally on the 0 and 14th days, and sensitized by inhalation on the 21st, 22nd and 23rd days. In the next 5 days, thymoquinone and carob were given to the group to be treated by intragastric gavage method. In all experimental groups, glutathione (GSH), ascorbic acid (AA), malondialdehyde (MDA) and nitric oxide (NOx) levels were measured spectrophotometrically to evaluate the oxidant-antioxidant status in the liver tissue of rats. While liver tissue GSH and AA levels increased, NOx levels were found to decrease following thymoquinone and carob administration in the treated group (A+TQ+C) when compared other groups (Control and Asthma). However, MDA levels, which are the indicator of lipid peroxidation, were found to be statistically significantly increased in the treated group (A+TQ+C) (

Effect of Fibroblast Growth Factor (FGF) on Some Serum Oxidative Parameters in Hyperglycemic Rats

Wound healing is a complex and dynamic process that includes multiple biological pathways and has some successive healing periods. Most growth factor is responsible for wound healing. Fibroblast growth factor has a positive effect on wound healing problems that can be caused by diabetes. In the present study, we aimed to investigate exogenous effect bFGF supplementation on serum TBARS, RSH and NOx levels in hyperglysemic rats. Experiments were performed on 30 male Wistar albino rats (weight range: 200-250 g ). Rats were hyperglycemic with STZ (ip, 60 mg/kg). The experimental groups were divided into untreated and bFGF-treated subgroups. bGF was applied locally to the dorsalateral wounds of rats (10 ng/ml). After these administrations, on the 3th and 7th days of wound healing, the animals were sacrificed. Serum TBARS, RSH and NOx levels were recorded spectrophotometrically. The results were expressed as mean ± Standard deviation and the mean differences were compared by Anova Variance Analysis (p lt;0,05). When compared with the treatment group, on the 7th day and the 3rd day, it was found that the serum TBARS levels increased statistically in hyperglycemic rats(p lt;0,05). Both in the 3rd day of the untreated and 3rd day of the rats treated with bFGF may significant decrease in the serum RSH levels. bFGF application was found both enhancing and reducing effects on oxidative stres. In subsequent studies, the effect of bFGF, which has positive effects on diabetic wound healing, on oxidative events can be investigated in detail using different doses and different treatment periods

Isatis Glauca Subsp. Sivasica Extract Contributes to Diabetic Wound Healing Process via Increased Collagen and Nitric Oxide Content

Isatis L. genus highly endemic and that is traditionally suggested for wound management in Turkey. In this study, we have reported the effect of I. glauca subsp. sivasica extract on diabetic wound healing process. A diabetic model was generated in Wistar rats using streptozotocin injection. Rats were divided into two main groups: control group and Isatis group. Full thickness excisional skin wounds were created by using a biopsy punch. The Isatis group was treated with single daily dose I. glauca subsp. sivasica extract (50 mg/kg). Rats were sacrificed day 3 or 7 after wounding. The dominant phenolic compounds identified with RP-HPLC-DAD from Isatis extract were the benzoic acid and vanillic acid. Isatis extract significantly accelerated wound healing process considering the wound closure rates (WCR). Moreover, the levels of collagen and nitric oxide were elevated on days 3 and 7 by Isatis administration in the diabetic wound tissue. These data suggest that, for the first time, I. glauca subsp. sivasica extract may have the potential to promote the impaired wound healing in patients with diabetes

Potential of morin and hesperidin in the prevention of cisplatin-induced nephrotoxicity

COSKUN CEVHER, SULE/0000-0001-6204-2845WOS: 000383902000020PubMed: 27425870Oxidative stress is one of the important mechanisms of cisplatin-induced nephrotoxicity. Therefore, this study was designed to explore the potential protective effects of morin and/or hesperidin on oxidative stress in cisplatin-induced nephrotoxicity. This study was performed on 42 Wistar rats. Rats were divided into seven groups: control, morin, hesperidin, cisplatin, cisplatin+morin, cisplatin+hesperidin, and cisplatin+morin+hesperidin. Morin and/or hesperidin were given for 10 consecutive days by oral gavage and on the 4th day a single dose of cisplatin (7mg/kg) was injected intraperitoneally. After administrations, on the 11th day of the experiment the animals were killed, and malondialdehyde (MDA), nitric oxide (NOx), glutathione (GSH) levels and myeloperoxidase (MPO), catalase (CAT), superoxide dismutase (SOD) activity were measured. Cisplatin-treated rats showed increased levels of MDA, and decreased levels of NOx also activity of CAT. Morin and/or hesperidin pretreatment prevent oxidative stress in kidney tissue, while they increase the NOx level, CAT activity, and decrease MPO activity. In conclusion, morin+hesperidin pretreatment may have a significant potential for protection of cisplatin-induced nephrotoxicity

Effect of dual growth factor administration on oxidative markers during acute stage wound healing in rats

WOS: 000412127600008\Wound healing is a complex process affected by various conditions, including oxidative stress. The present study explored the time-dependent effects of platelet-derived growth factor (PGDF) and vascular endothelial growth factor (VEGF) administration on oxidative markers during acute stage wound healing. Thirty-six Wistar rats were distributed into three major groups; skin wounds were inflicted in all groups. The wounds were either left untreated (control group), treated topically with blank chitosan gel (blank chitosan gel group), or treated topically with a combination of PDGF and VEGF in chitosan gel (PDGF + VEGF chitosan gel group). Wounds were sampled on postsurgery days 3 and 7; samples were assayed for the oxidant markers nitric oxide (NOx) and thiobarbituric acidreactive substances (TBARs) and the antioxidant markers glutathione (GSH), ascorbic acid (AA), and superoxide dismutase (SOD) activity. PDGF + VEGF administration increased and decreased NOx levels on days 3 and 7, respectively. PDGF + VEGF administration lowered TBARs levels, compared with blank chitosan gel administration, on day 7. PDGF + VEGF administration increased GSH levels. These results demonstrate that PDGF + VEGF administration changes oxidative status of wound tissue. This study provides valuable insights for the development of therapeutic targets that promote wound healing

Morin and hesperidin ameliorate cisplatin-induced hepatotoxicity and nephrotoxicity in rats: a histopathological study

WOS: 000434277000006In this study, we investigated that the histopathological changes of rat kidney and liver tissues after cisplatin administration and potential beneficial effects of morin and hesperidin administration. Wistar rats were randomly divided in 7 groups: control, morin (M), hesperidin (H), cisplatin (CP), cisplatin+morin (CP+M), cisplatin+hesperidin (CP+H), cisplatin+morin+hesperidin (CP+M+H). Kidney and liver tissues were collected at the end of the experiment and were evaluated histopathological changes. Various histopathological changes in kidney and liver tissues of cisplatin-induced group were revealed. However, pre- and co-treatment of morin and/or hesperidin partially prevented these hepatotoxic and nephrotoxic changes in cisplatin-induced groups
