Abstract Purpose This study aimed to evaluate the effects and mechanisms of action of royal jelly (RJ) and propolis in an animal model of oral mucositis (OM).Methods Seventy-two male Wistar rats were randomly allocated to four groups (n = 18): control (no treatment), PBMT (intraoral laser, 6 J/cm2), RJ, and propolis. On days 0 and 2, animals received injection of 5-fluorouracil (5-FU). The buccal mucosa was scratched (days 3 and 4) and the treatments were initiated on day 5. Six animals of each group were euthanized on days 8, 10, and 14. Phytochemical analysis (thin-layer chromatography-TLC), clinical, histopathological, immunohistochemical of pS6, pAKT and NF-κB and oxidative stress markers were also investigated.Results TLC revealed the presence of large amounts of sucrose (Rf 0.34) in RJ and flavonoids in propolis. On day 8, lower clinical OM scores (and day 10) and morphological were observed in the PBMT, RJ and propolis groups (p < 0.05). On day 8, immunoexpression of pS6, pAKT and NF-κB was increased when compared to control. On day 14, GSH antioxidant levels were increased in the propolis group compared to control (p < 0.05).Conclusions Our results showed that RJ and propolis, as well as PBMT, are effective in the treatment of OM. The RJ and propolis may explain their excellent wound healing activity and anti-inflammatory effects. Considering that not all patients who develop OM have access to PBMT, the present study demonstrated that topical application of RJ and propolis may be an important alternative for the treatment of OM.

Introduction: Cnidoscolus aconitifolius is considered to be an important and effective medicinal plant in folklore remedies where it has been applied as an alternative therapy for the treatment of various ailments. Aim: The present study aims to determine the effects of Cnidoscolus aconitifolius on lipid profile and some oxidative stress markers of male Wistar rats. Methodology: A total of 15 male wistar rats were procured for the study and randomly assigned into three groups of 5 rats each. Group 1 served as control and received distilled water only. Group 2 received 200 mg/kg and group 3 received 400mg/kg of the hydromethanolic (1:4) extract of Cnidoscolus aconitifolius which was administered as single daily dose using oral cannula. On completion of treatment, blood samples were collected by cardiac puncture for determination of some serum lipid parameters and oxidative stress markers. Results: Results showed that there were no significant difference in the serum level of total cholesterol, triglyceride, low density lipoprotein cholesterol and high density lipoprotein cholesterol at both doses of the extract, compared to control. However, compared to control, there was a significant (p<0.05) increase in the activity of superoxide dismutase and glutathione reductase but significant reduction in malondialdehyde level. The catalase enzyme activity was not significant. Conclusion: The result obtained suggest that the extract may be useful in reducing oxidative stress by improving some antioxidant enzyme activities and may also prevent cell death due to lipid peroxidation.

The aim of the present study was to evaluate the subchronic effects of 3,4-methylenedioxymethamphetamine on several oxidative stress markers: index of lipid peroxidation (ILP), superoxide dismutase (SOD) activity, superoxide radical (O2.-) levels, and reduced glutathione (GSH) levels in the frontal cortex, striatum and hippocampus of the rat. The study included 64 male Wistar rats (200-250g). The animals were treated per os with of 5, 10, or 20 mg/kg of 3,4-methylenedioxymethamphetamine (MDMA) every day for 15 days. The subchronic administration of MDMA resulted in an increase in ILP, SOD and O2.-, and a decrease in GSH, from which we conclude that oxidative stress was induced in rat brain.

Abstract Medicinal plants, such as E. pyramidale, are alternatives against infections and assist in the healing process of wounds. We evaluated the effects of Hydrogel of E. pyramidale on the healing of cutaneous wounds in animal models by morphological, morphometric and histological analyses, and elucidated major components. The ethanolic extract of E. pyramidale shoots was submitted to phytochemical analysis. For cicatrizing activity assay, Wistar rats were used, and the groups evaluated were hydrogel containing ethanolic extract of E. pyramidale at 2% compared to control groups. The treatment periods were 3, 7 and 21 days, and macroscopic and microscopic analyses were performed. Data were submitted to Analysis of Variance (p <0.05). Phytochemistry and quantification evidenced that flavonoids are main constituents and that they were evidenced by thin layer chromatography (TLC), high efficiency (HPLC) and infrared (IR) methods. In TLC, using flavonoid patterns, we observed pinocembrin. The hydrogel containing ethanolic extract of E. pyramidale at 2% was effective in wound regression. E. pyramidale can be used for the treatment of second intention wounds, and the effective healing may be due to a high flavonoid content.

Background: Although ethanol exerts its neurotoxic effect on the brain through inflammatory and oxidative processes, the effect of Riboceine on the brain following ethanol neurotoxicity is yet to be elucidated. Therefore, this study was designed to evaluate the effects of riboceine on the cellular, behavioral, and molecular impairments induced by ethanol toxicity in rats. Methods: A total of 24 male Wistar rats weighing between 160-170 grams were used for the study, and were divided into four groups of six rats each. After completion of the administration of ethanol and riboceine, and testing for motor impairment, the rats were sacrificed. The cerebellum was excised and processed for oxidative stress analyses, based on oxidative stress markers and histological examinations. The immunohistochemical expression of astrocytes in the cerebellum was examined, using Glial Fibrillary Acidic Protein (GFAP) stain. Results: This study demonstrated that ethanol-induced neurotoxicity in the cerebellum, characterized by increased oxidative stress profile, astrocyte activation, and neuronal death in the cerebellum, especially the Purkinje layer. Necrosis, significant decrease in Superoxide Dismutase (SOD), Catalase (CAT) and Gluathione (GSH) activities (P<0.05) as well as astrogliosis was associated with ethanol treatment. However, riboceine was observed to significantly increase the cerebellar SOD, CAT and GSH activities with significantly reduced Malondialdehyde (MDA) levels (P<0.05). It also attenuated the histomorphological alteration of the cerebellum and reduced the cerebellar astrocytes activation following ethanol-induced neurotoxicity, thus leading to the attenuation of motor impairment. Conclusion: Riboceine attenuated motor impairment caused by chronic ethanol-induced neurotoxicity, suggestive of its anti-oxidative and anti-inflammatory properties.

The qualitative composition of phenolic acids and burn wound healing activity of Prunella grandiflora L. extract were studied. The content of rosmarinic (621±5 mg/g), coffeic (11.2±0.2 mg/g), syringic (46.5±1.4 mg/g), n-coumaric (25.8±0.5 mg/g), and ferulic (42.7±2.9 mg/g) acids in dry extracts of P. grandiflora was determined by HPLC. Three new burn-healing agents of different composition containing 5% of the dry extract of Prunella grandiflora L. (big-flowered self-heal) were developed. The developed agents were tested on male Wistar rats with second- and third-degree thermal burns. An assessment of skin restoration was carried out in experimental and control groups of animals. It was revealed that animals treated with the developed soft dosage forms restored the epithelium and coat 6–8 days faster that those treated with compositions containing no extract under study. It was found that the developed soft dosage forms based on P. grandiflora extract exhibit anti-inflammatory and wound-healing action.
