Abstract Purpose: There are multiple and specific phases during wound healing. Resveratrol (RSV) is a polyphenol compound found naturally in fruits. Resveratrol's antioxidant, anti-aging, cardioprotective, anti-inflammatory, and anti-carcinogenic effects have been shown. This study aims to determine the effects of RSV on perfusion, neovascularization, inflammation, and granulation stages of wound healing in addition to its antioxidant capacity over GPX and SOD.Methods: 16 female rats were divided into two groups as the RSV and control groups. Six excisions were made in each rat. Three excisions in each rat were sutured and the other 3 were left as open wounds. Topical RSV was applied to the wounds of the rats in the RSV group. No treatment was given to the control group. Blood perfusion of the wounds in both groups were measured using the PeriScan PIM 3 System Laser Doppler Blood Perfusion Imager. Punch biopsies were taken for histopathological examinations and for the evaluation of SOD, GPX, and MDA.Results: GPX level of the closed wounds belonging to the RSV group was higher compared to the control group. There was no statistically significant difference in SOD and MDA levels between the groups. Neovascularization was registered higher in the open wounds of RSV group. Conclusion: Within parameters, resveratrol has been shown to be effective in wound healing in various ways. The results of this study may shed light on new therapeutic approaches that can be used in the reversal of oxidative stress in wound-causing diseases.

Background and Objectives: Nephrotoxicity is one of the limiting factors for using doxorubicin as an anticancer chemotherapeutic. Reactive oxygen species and cytokines have been implicated in the nephrotoxicity induced by doxorubicin. The main objective of the present study is to identify and compare the histomorphological features in kidneys of albino rats and gross morphological features such as weight of rats and weight of the kidneys due to administration of doxorubicin. Materials and Methods: In the study, albino rats were taken as the animal model. Sixty animals were taken as the sample size. They were divided into two equal groups: experimental (n=30) and control (n=30). Rats of experimental group were treated with anticancer drug doxorubicin at a single intraperitoneal dose of 10 mg/kg body weight while the Control group of rats received a similar volume of 0.9% normal saline. The ethical clearance was taken prior to the research from IERB committee BPKIHS Dharan.  Results: Our results showed that there was high effect of drug in experimental groups of rats. It was seen that there was significant decrease in the body weight and weight of kidneys. The final body weight and kidney weight between experimental and control group showed the significant difference. Similarly there were no significant differences in the normal architecture between the male and female rats. The normal renal histological features were seen on the kidneys in the control group whereas the rats intervened with the drug had some disrupted histological features which reveal the toxicity of the drugs in the kidneys. Conclusion: The study showed toxicity of the drug in the kidneys of experimental groups of rats irrespective of gender and suggest that doxorubicin causes significant loss of the body weight and weight of kidneys and causes the disruption in the normal histological features.

Split-thickness skin grafting (STSG) is widely used to heal wounds resulting from trauma, burns, and chronic wounds. This study aimed to determine the true effect of platelet-rich fibrin (PRF) on patients with burn wounds requiring STSG during treatment of donor wounds. This randomized, triple-blind clinical trial was conducted on patients who referred to the burn ward of Vasei Hospital of Sabzevar, Iran, from May 2017 to May 2018. The donor site was randomly divided into 2 groups: PRF and control (Vaseline petrolatum gauze) using Vaseline gauze. In the intervention group, the PRF gel was applied to the wound and covered with Vaseline gauze and wet dressing. Conversely, only Vaseline gauze and wet dressing were applied to the control group. Outcome evaluation was conducted using paired t test and Wilcoxon signed rank-sum test, as appropriate, on days 8 and 15. The mean age of the patients was 33.10 ± 2.60 years, and 51.50% were male. The mean wound healing time in the PRF and control groups was 11.80 ± 3.51 and 16.30 ± 4.32 days, respectively ( P < .001). The PRF group showed significantly higher wound healing rates than the control group at 8 and 15 days dressing ( P < .001 and P < .001, respectively). Moreover, the mean wound healing for all wound healing indices diagnosed by 2 specialists in PRF was higher than control group on days 8 and 15 ( P < .001). We found a statistically significant difference on days 8 and 15 regarding the mean pain levels between the 2 groups ( P < .001). The findings showed that PRF can significantly increase the time and rate of donor wound healing compared with conventional treatment and also reduce the severity of pain.

Objectives. The present study was aimed at investigating the wound healing effect of ethanolic extract of Cestrum nocturnum (L.) leaves (EECN) using excision and incision wound model. Methods. Wistar albino rats were divided into five groups each consisting of six animals; group I (left untreated) considered as control, group II (ointment base treated) considered as negative control, group III treated with 5% (w/w) povidone iodine ointment (Intadine USP), which served as standard, group IV treated with EECN 2% (w/w) ointment, and group V treated with EECN 5% (w/w) ointment were considered as test groups. All the treatments were given once daily. The wound healing effect was assessed by percentage wound contraction, epithelialization period, and histoarchitecture studies in excision wound model while breaking strength and hydroxyproline content in the incision wound model. Result. Different concentration of EECN (2% and 5% w/w) ointment promoted the wound healing activity significantly in both the models studied. The high rate of wound contraction (P<0.001), decrease in the period for epithelialization (P<0.01), high skin breaking strength (P<0.001), and elevated hydroxyproline content were observed in animal treated with EECN ointments when compared to the control and negative control group of animals. Histopathological studies of the EECN ointments treated groups also revealed the effectiveness in improved wound healing. Conclusions. Ethanolic extract of Cestrum nocturnum (EECN) leaves possesses a concentration dependent wound healing effect.

Background: Infection can lead to delayed wound healing. Recently it has been shown that propolis which is used in complementary medicine has an antibacterial and anti-inflammatory effect. The aim of this study is to determine whether propolis may contribute to wound healing. Material and Methods: Twenty-one male Wistar albino rats were randomly divided into three groups. Group1 and Group 2 were topically treated with propolis ointment and Thiocillin® oinment, respectively while Group 3 was the control group. On incision wound model, Thiocillin® and propolis ointments were applied on wound sites once daily for 30 days and the mean epidermal thickness (MET) at the 30th day was compared while antimicrobial activity of propolis was studied against different pathogens as well. Results: Propolis exhibited in vitro antibacterial activity against Staphylococcus aureus, Escherichia coli, Streptococcus sp. and Pseudomonas sp. It is observed that the MET in the groups of Propolis ointment and Thiocillin® ointment were significantly greater than that of the control group, while the MET in the group of propolis ointment was significantly greater than that of Thiocillin® ointment treated group. Conclusion: Propolis is effective in wound healing. Further study in-depth is necessary to probe into clinical correlation.

This study was conducted to prove whether ellagic acid can be used as a regulator of incision wound healing process in male albino rats as experimental animals. A total of 24 male healthy rats based on physical examination, aged at 3 months old and weight at 150-180 grams used in this study. Rats were divided into three groups and each group has 8 replications, group of control (P0) has no incision wound and no medication, treatment group (P1) has incision wound and treated with Betadine® and (P2) has incision wound and treated with 2,5 % ellagic acid. The variable that observed are histopathology changes (collagen, PMN, angiogenesis and fibrosis) from the male albino rats. The samples collection was taken at day 15 and data were collected and analyzed by Analysis of Variance (ANOVA) test. The result of collagen and PMN cells score in the control group (P0) were 1.80 ± 0.16 and 1.6 ± 0.08 with mild angiogenesis and no fibrosis. The results in the treatment (P2) group, where the collagen and PMN scores were 1.60 ± 0.08 and 1.5 ± 0.8, accompanied by mild angiogenesis and fibrosis. Meanwhile, in the treatment (P1) group, the results of scoring of collagen and PMN were lower than the other groups, 0, 80 ± 0.08 and 0.6 ± 0.16 accompanied by moderate angiogenesis and fibrosis. There was a significant difference of collagen scoring, PMN cells number, fibrosis and angiogenesis among the treatment groups (p<0.05). P1 treatment group has significant different with treatment groups P0 and P2 (p<0.05), but there is no significant difference between treatment groups P0 and P2 (p>0.05).  From the results, it can be concluded that the topical application of ellagic acid ointment was proved to provide healing process on incision wound. Topical administration of ellagic acid ointment for 14 days was able to improve the skin condition and promoted the wound healing.Keywords: Ellagic acid ; wound healing ; collagen ; angiogenesis ; fibrosis ; anti-inflammatory ; antioxidant ; antibacterial.

The objective of the present study was to perform histological and stereological examination of alcohol-induced changes in the optic nerve, considered an extension of white matter of the brain, in rats. This study included 20 male Wistar albino rats aged 60 days and weighing 190–220 g. The rats were divided into three groups: ethanol ( n = 7), maltodextrin ( n = 7), and control ( n = 6) groups. The ethanol group was administered ethanol at a dose of 6.4% (v/v) instead of water for 18 days; the maltodextrin group received maltodextrin for the same time period, and the control group was the sham group. At the end of the experiment, a 0.5-mm long section of the optic nerve starting from the optic chiasma was dissected and examined with routine microscopic histological examination methods. The modified Cavalieri method was used for stereological measurement. Total tissue area ratios were calculated with a point grid provided by the Shtereom 1.5 software package. The statistical comparison of the groups revealed that the ethanol group had a significant reduction in the number of axons and sheath area of the optic nerve compared to the control and maltodextrin groups ( p < 0.017, p < 0.022, respectively). These results indicate the toxic effects of ethanol on the optic nerve.

Aim: The role of nutrition in lipid metabolism continues to generate a lot of research interest, especially as dyslipidaemia is implicated in a host of diseases. The work investigated the effect of ethanol extract of  Curcubita pepo leaves on the lipid profile of Wister rats. Methodology: A total of 18 rats divided into three groups of 6 rats each were employed in the investigation. The first group (baseline) was sacrificed after purchase; second group (control) was fed rat chow, and the third group (test) was fed a composite feed containing rat chow and 10% extract of C. pepo leaves.  Results: The lipid profile (total cholesterol, triglycerides, LDL, HDL and VLDL) of the rats was assayed after 18 days of feeding and the result showed no significant difference (P>0.05) between the test group and control for the lipids assayed. However, there was a marked increase in the HDL level of the test group (0.500±0.057 mmol/L) compared to the control (0.268±0.043 mmol/L), it was nonetheless statistically non-significant (P=0.068).  The HDL increasing effect observed may stem from the rich phytochemistry of the leaves, as preliminary phytochemical investigation showed the leaves to contain saponin, tannin, alkaloids, flavonoids and glycosides. Conclusion: We conclude that the leaves of C. pepo may play a medicinal role in maintaining lipid homeostasis.
