摘要:AbstrakBerbagai penelitian ilmiah telah membuktikan bahwa kolagen merupakan biomaterial ideal dalam aktivitas penyembuhan luka. Senyawa bioaktif pada madu dan Aloe vera dapat membantu meningkatkan pembentukan kolagen. Penelitian ini dilakukan untuk membandingkan pengaruh aplikasi topikal madu, gel Aloe vera, dan Moist Exposed Burn Ointment (MEBO) terhadap kepadatan kolagen pada proses penyembuhan luka bakar derajat dua pada tikus. Luka bakar dibuat pada 28 ekor tikus dan dibagi menjadi empat kelompok yang dipilih secara acak serta dilakukan aplikasi topikal harian dengan NaCl, madu, gel Aloe vera, dan MEBO secara berurutan. Biopsi kulit dilakukan pada hari ke-7, kemudian dilakukan pembuatan sediaan histopatologi kulit dan dihitung kepadatan kolagennya. Uji One Way ANOVA menunjukkan kepadatan kolagen berbeda secara signifikan antar masing-masing kelompok (p= 0,009). Uji Post Hoc Bonferroni menunjukkan terdapat perbedaan yang signifikan antara kelompok NaCl dengan madu (p= 0,024) dan NaCl dengan MEBO (p= 0,024). Penelitian ini menunjukkan bahwa aplikasi madu dan MEBO secara topikal pada luka bakar derajat dua dapat meningkatkan pembentukan kolagen, sehingga dapat mempercepat proses penyembuhan luka. Madu, Aloe vera, dan MEBO dapat dijadikan sebagai terapi alternatif dalam penyembuhan luka bakar.?AbstractVarious scientific studies have proven that collagen is an ideal biomaterial in wound healing activities. The bioactive compounds in honey and Aloe vera can help increase collagen formation. This study was conducted to compare the effect of topical application of honey, Aloe vera gel, and MEBO (Moist Exposed Burn Ointment) on collagen density in the healing process of second-degree burns in rats. Burns were made on 28 rats which were further randomly divided into four groups to receive daily topical application of NaCl, Aloe vera, honey, and MEBO respectively. Skin biopsy was carried out on the seventh day, then histopathological preparation of the skin was made and collagen density was calculated. Result of One Way ANOVA test showed that collagen density differed significantly between groups (p= 0.009). The Post Hoc Bonferroni test resulted in significant difference between NaCl with honey group (p= 0.024) and NaCl with MEBO (p= 0.024). This study found that topical application of honey and MEBO to second-degree burns could increase collagen formation, thus accelerating wound healing process. Honey, Aloe vera, and MEBO can be used as alternative therapies for healing burns.
摘要:The presence of necrotic tissue is one of the major problems that affect healing of burn wounds. The present study was designed to find the effectiveness of collagenase versus moist exposed burn ointment (MEBO) on removal of necrotic tissue of burns. Twenty mice randomly assigned and divided into four groups. For Group 1, burn wounds were treated with collagenase ointment only, Group 2 burn wounds were treated with MEBO, Group 3 burn wounds were treated with white vaseline alone, and Group 4 burn wounds were considered as control and left without treatment. In each group, the time of treatment was considered. The results indicated that the removal time of necrotic tissue and healing process was better in the case of using collagenase than using MEBO for treatment of burns.
摘要:A simple, rapid, and reproducible high-performance liquid chromatography (HPLC) method has been developed and validated for the determination of β-sitosterol in the pharmaceutical dosage form of moist exposed burn ointment (MEBO). This method involved an effective sample procedure for extraction of β-sitosterol from MEBO using an alkali saponification agent composed of 0.8?N ethanolic NaOH and diethyl ether. The chromatographic separation was achieved on a C18 column (50?×?3.0?mm, 2.5?μm), using a mobile phase composed of methanol and acetonitrile (70:30 v/v) pumped in an isocratic mode at a flow rate of 0.7 mL/min. The column temperature was maintained at 40?°C, the injection volume was 10 μL, and the detection wavelength was 203?nm. Employing these conditions, the retention time was found to be 2.10?min. The developed method was validated for its specificity, linearity, accuracy, precision, the limit of detection, the limit of quantification, robustness, and solution stability based on International Council for Harmonisation (ICH) guidelines Q2 (R1). Our proposed method demonstrated superior performance compared to other reported methods. It exhibited a linearity range of 30 to 500?μg/mL and improved detectability with a limit of detection (LOD) of 4.65?μg/mL, highlighting its high sensitivity. Additionally, the separation was achieved in a remarkably short analysis time of just 2.1?min, which not only enhanced throughput but also significantly minimized waste and solvent consumption, thereby making it a more sustainable and effective alternative for β-sitosterol extraction. Moreover, in the light of green and white analytical chemistry, a comprehensive ecological and sustainable tri-color coded assessment protocol was established. The proposed method has been successfully applied to quantify β-sitosterol in commercial products (MEBO?, Avomeb? and BISTROl?) demonstrating its suitability for routine quality control analysis of β-sitosterol in pharmaceutical ointment dosage forms.
摘要:Introduction The objective was to investigate the clinical effect of an adjustable pulse width Pulsed Dye Laser (PDL) vs an adjustable pulse width PDL combined with fractional CO2 laser in treating immature red hypertrophic scars. Methods Fifty-six patients (56 sites)were randomly divided into a treatment group and control group. The control group was treated with the 595 nm PDL at a fluence of 7-15J/cm2 and pulse widths of 1.5-3 ms, 7 mm spot size. The treatment group was treated with a fractional CO2 laser (UltraPulse CO2: Deep FX, Energy: 30 50 mJ, Frequency: 300 Hz, Density 5%, Scan Shape, and Spot Size were decided by shape and area of scar) after utilizing the 595 nm adjustable pulse width PDL (Fluence: 7-15J/cm2, Pulse widths: 1.5-3 ms, Spot size: 7 mm). MEBT/MEBO, previously described as a post-treatment wound ointment, was used after laser treatment. The scars of the treatment group and the control group were evaluated for changes in pigment, height, vascularity, and pliability using the Vancouver Scar Scale (VSS) after two laser treatments. Results The total VSS score, as well as the score for melanin, height, vascularity, pliability in both groups, showed an obvious decrease following the treatments. There were statistically significant differences between before treatment and after treatment (P < .05); however, the total score of the VSS, and score of the melanin, height, vascularity, and pliability in the control group decreased more than that of treatment group, and there was a statistically significant difference (P < .05). Conclusions The 595 nm adjustable pulse width PDL combined with the fractional CO2 fractional laser appears to have a beneficial clinical effect on fresh red hypertrophic scars, with no severe adverse reactions seen.
