Effectiveness of green betel leaf extract cream in healing cut wounds

Green betel leaf (Piper betle L.) is widely used in the healing of cut wounds. The aim of this study was to investigate the efficacy of green betel leaf extract cream in the healing of cut wounds on the skin of white Wistar rats. The design employed was a pre-test post-test with a control group design and a sample size of 20 white rats divided into four groups. Betel leaf extract was prepared using the maceration method, while a cream preparation of betel leaf extract was prepared using the oil-in-water emulsion type (M/A). Macroscopic histopathological evaluation was performed by examining fibroblast growth. A one-way analysis of variance (ANOVA) test (p < 0.05) was used to determine the difference between groups, and a post hoc least significant difference (LSD) test was used to analyze which treatment group had the greatest efficacy. Technical terms were explained upon first use, and the language used was clear, objective, and value-neutral to improve academic quality. The text was free from grammatical errors, spelling mistakes, and unnecessary jargon. A one-way analysis of variance (ANOVA) test (p < 0.05) was used to determine the difference between groups, and a post hoc least significant difference (LSD) test was used to analyze which treatment group had the greatest efficacy. The study revealed a substantial difference in the average wound healing rates between the control group (P0) and treatment groups P1, P2, and P3. This is due to the lack of active substances in the control group (P0), which aids in accelerating the wound healing process. Notably, the 15% green betel leaf extract cream demonstrated superior efficacy in healing wounds in white rats compared to the 10% and 25% green betel leaf extract creams. The results indicated no significant difference between the application of 15% and 25% green betel leaf extract cream. This is due to the fact that secondary metabolite compounds present in the extract produce a healing effect on wounds at these particular levels. However, lower concentrations only act as microorganism inhibitors, rendering them less effective for promoting wound healing.

Although immunotherapies are ideal, its clinical safety and effectiveness are controversial, hence, treatments are still reliant on symptomatic medications. Concurrently, the Streptomyces genus has attracted attention given its pharmaceutically beneficial secondary metabolites to treat neurodegenerative diseases. To present secondary metabolites from Streptomyces sp. with regulatory effects on proteins and identified prospective target proteins for AD treatment. Research articles published between 2010 and 2021 were collected from five databases and 83 relevant research articles were identified. Post-screening, only 12 research articles on AD-related proteins were selected for further review. Bioinformatics analyses were performed through the Search Tool for the Retrieval of Interacting Genes/Proteins (STRING) network, PANTHER Go-Slim classification system (PANTHER17.0), and Kyoto Encyclopedia of Genes and Genomes (KEGG) Mapper. A total of 20 target proteins were identified from the 12 shortlisted articles. Amyloid-β, BACE1, Nrf-2, Beclin-1, and ATG5 were identified as the potential target proteins, given their role in initiating AD, mitigating neuroinflammation, and autophagy. Besides, 10 compounds from Streptomyces sp., including rapamycin, alborixin, enterocin, bonnevillamides D and E, caniferolide A, anhydroexfoliamycin, rhizolutin, streptocyclinone A and B, were identified to exhibit considerable regulatory effects on these target proteins. The review highlights several prospective target proteins that can be regulated through treatments with Streptomyces sp. compounds to prevent AD's early stages and progression. Further identification of Streptomyces sp. compounds with potential anti-AD properties is recommended.

Potential of gambier leaf ethanol extract cream for incised wound healing

Incised wounds are highly susceptible to bacterial infection, which requires stimulation of healing and restoration of normal function of the injured body part. This study aimed to test the effect of gambier leaf ethanol extract cream administration on the acceleration of wound healing on the skin surface of male Wistar rats. The research used a pre-test post-test with a control group design. Twenty male white rats were divided into four groups: control group (P0), treatment group 1 (P1), treatment 2 (P2), and treatment 3 (P3). The incision wounds in white rats were treated twice a day (in the morning and evening) for 14 days. Wound healing was observed by measuring the average length of the wound every day, from the first day of wounding until day 14. Statistical tests used were one-way ANOVA and post-hoc LSD test (p < 0.05). In this study, it was found that the 15% gambier leaf extract cream was more effective in wound healing in white rats than the 5% and 7.5% gambier leaf extract creams. However, in the group treated with 7.5% gambier leaf extract cream, the situation was already close to that in the treatment group treated with 15% gambier leaf extract cream. This is because, at a concentration of 7.5%, the secondary metabolite compounds in the gambier leaf extract had an effect on wounds, but at a concentration of 15% gambier leaf extract cream, the effect was similar to that of 15% gambier leaf extract cream.

Effectiveness of red betel leaf extract cream for healing burn wounds

Burns are a frequent type of wound that can cause complications, infection and bleeding. The use of plants and natural materials as wound-healing remedies has been known for a considerable period, although more scientific proof is required. The objective of this investigation is to examine the efficacy of red betel leaf extract ointment in curing burns on the backs of white wistar rats. The study used a pre-test post-test design with a control group. Twenty white rat samples were employed. The samples were split into four groups, consisting of five rats each. Betel leaf extract was prepared through maceration, whilst betel leaf extract cream was made using the oil-in-water emulsion method (M/A). A histopathology test was carried out to observe growth of fibroblast cells. Rat skin biopsy was taken from a 2 x 2 cm area, and data normality was tested with the Shapiro-Wilk test (p > 0.05). The One-way Anova test (p < 0.05) was used to assess the differences between the groups. To determine the most effective treatment group, a post hoc test using LSD technique was performed. The findings showed that the average percentage of burn wound healing in the control group (P0) compared to groups P1, P2, and P3 was very different. The analysis reveals that the application of 15% betel leaf extract cream proves to be superior in treating burns in white mice in contrast to 7.5% and 10% betel leaf extract cream. At a 15% concentration, secondary metabolite compounds found in betel leaf extract are already effective in treating wounds. However, at lower concentrations they only inhibit microorganisms, making them less effective in promoting wound healing.
