Partial Thickness Burns

Abstract An ideal dressing should ensure that the wound remains moist with exudates but not macerated. Currently, there is no dressing available to suit all wounds, at all stages of the healing process. Although silver-containing dressings are the gold standard for burn wound care, few high-level trials have been completed comparing the clinical utilities of these dressings. In our study, five different types of wound dressings: carboxymethyl cellulose hydrofiber dressing with ionized silver (CMCH-Ag), polyethylene-polyethylene terephthalate aqua fiber dressing with elementary silver (PPAF-Ag), calcium alginate (CA), calcium + zinc alginate (CZA), and 0.2% nitrofurazone-embedded (NF) gauze dressings were compared in regard to histopathological parameters. Children aged between 0 and 18 years with small or middle-sized partial-thickness burns that affected less than 30% of the total body surface area were included in this study. The study groups (CMCH-Ag, PPAF-Ag, CA, and CZA) and the control group (NF) were randomly attained. Wound healing was evaluated by punch biopsies on the 21st day. The thickness of the stratum corneum and the epithelium, the number of papillae, and the papillary length were calculated and compared. The histological parameters of healing, except the stratum corneum thickness, did not show any statistical significance among the groups (P > .05). The dressings that included silver, calcium, or zinc showed useful and similar effects in noninfective burn wounds when compared with nitrofurazone-only dressings. Thus, it may be concluded that silver-containing wound dressings should not be considered as the gold standard in noninfective partial-thickness burn wounds in children.

Abstract Chromium is an extremely toxic metal in the form of Cr (VI) that causes severe environmental and health problems. Therefore, the aim of this study was to remove chromium ions from wastewater by using cost effective and environmentally friendly bio-sorbents; Moringa stenopetala Seed Powder (MSSP), and Banana Peel Powder (BPP) and to evaluate its adsorption capacities as bio-sorbents. FT-IR characterization of the adsorbents showed that there was a change in the functional groups of the structure of both adsorbents before and after the adsorption that might be due to the adsorption processes taken place on the surface of adsorbent. Adsorption experiments were carried out as batch studies with different contact times, pH, adsorbent dose, initial metal ion concentration, and temperature. Results showed maximum removal efficiency for Cr (VI) at 120 minutes contact time, adsorbent dose of 20 g/L and pH 2 by MSSP and pH 4 by BPP. The percentage removal of Cr(VI) increased with increasing adsorbent dose( from 5g/L to 20 g/L) and contact time (from 60 min to 120 min). Freundlich isotherm model showed a better fit to the equilibrium data than the Langmuir model. The kinetics of adsorption for chromium was well represented by pseudo-second order kinetic model and the calculated equilibrium sorption capacity of the model showed good agreement with the sorption capacity obtained from Experimental results.

AbstractBanana is second largest produced fruit of total world’s fruits. Cooking banana or plantains processing industry is generating enormous amount of waste in the form of unripe banana peel at one place, thus important to study waste management and utilization. Therefore, unripe banana peel was investigated for ethanol production. This study involved chemical characterization, optimization of acid hydrolysis, selection of yeast strain and optimization of fermentative production of ethanol from dried unripe banana peel powder (DUBPP). Ethanol concentration was determined using gas chromatography flame ionization detector (GC-FID). Characterization of DUBPP revealed notably amount of starch (41% w/w), cellulose (9.3% w/w) and protein (8.4% w/w). 49.2% w/w of reducing sugar was produced by acid hydrolysis of DUBPP at optimized conditions. Three yeast strains of Saccharomyces cerevisiae were screened for ethanol conversion efficiency, osmotolerance, ethanol tolerance, thermotolerance, fermentation ability at high temperature and sedimentation rate. Further, fermentation conditions were optimized for maximum ethanol production from acid hydrolysate of DUBPP. At optimized fermentation conditions, 35.5 g/l ethanol was produced using selected strain of Saccharomyces cerevisiae NCIM 3095. Hence, unripe banana peel waste can be good feedstock for ethanol production.

The need for pectin in Indonesia is inscreasing every year. Indonesia relies on pectin import to fulfill domestic pectin needs. So it is necessary to search for sources of raw materials that contain pectin, one of which is banana peel waste. Pectin in banana peels can be extracted using acid solvents. This study aims to determine the effect of the ratio of banana peel powder and solvents (1:40, 1:50, and 1:60) to the yield and quality of pectin extracted. The acid solvent used was 5% citric acid, and the extraction was conditioned at 90 °C for 120 minutes. Pectin which has been extracted from banana peels is in powdered form, brownish, and odorless. The results showed that the optimum solvent/solid ratio was 1:50 with a quantity of yield, equivalent weight, methoxyl content, galacturonic acid content, and esterification degree were 10,68%, 958 mg, 3,54%, 196% and 14,84% respecively. FTIR analysis indicated that pectin from banana peels extract had characteristic near to comercial pectin. Keyword: pectin extraction, ratio peel powder and solvents, citric acid volume Kebutuhan pektin di Indonesia cenderung meningkat di setiap tahun dan lebih mengandalkan pektin impor untuk memenuhi kebutuhan pektin dalam negeri. Oleh karena itu perlu dilakukan pencarian sumber bahan baku yang memiliki kandungan pektin, diantaranya adalah kulit pisang. Pektin dalam kulit pisang dapat diekstrak menggunakan pelarut asam. Penelitian ini bertujuan untuk mengetahui pengaruh volume asam yang ditambahkan pada serbuk kulit pisang raja nangka dengan rasio 1:40, 1:50, dan 1:60. Pelarut asam yang digunakan adalah asam sitrat 7% dengan suhu estraksi 90 °C dan lama waktu ekstraksi 120 menit. Pektin yang telah diekstrak dari kulit buah pisang ini berbentuk serbuk, berwarna kecoklatan, dan tidak berbau. Hasil penelitian menunjukkan bahwa rasio bahan/pelarut adalah 1:50 dengan hasil rendemen, berat ekivalen, kadar metoksil, kadar galakturonat, dan derajat esterifikasi berturut-turut adalah 10,68%, 958 mg, 3,54%, 196% dan 14,84%. Analisis dengan FTIR menunjukkan bahwa bilangan gelombang yang muncul pada pektin dari kulit pisang ini memiliki karakteristik yang sama dengan pektin komersial. Kata kunci: ekstraksi pektin, volume asam sitrat, rasio bahan dan pelarut
