Objective: The main objective of the research work was to fabricate sacran hydrogel film containing keratinocyte growth factor (Sacran/KGF-HGF), and to evaluate their wound healing ability in alloxan-induced diabetic mice model.Methods: The physicochemical characterization of Sacran/KGF-HGF were investigated by thickness, tensile strength, swelling ratio, x-ray diffractometer (XRD), scanning electron microscope (SEM), and biodegradability. The wound healing ability was investigated by creating two full-thickness excisional wounds inalloxan-induced diabetic mice.Results: The thickness, tensile strength, and swelling ratio results showed that KGF in the Sacran/KGF-HGF improved not only the thickness of sacran hydrogel film (Sacran-HGF), but also the tensile strength and swelling ability of Sacran-HGF. The XRD and SEM results confirmed that the Sacran/KGF-HGF were amorphous and similar morphology to Sacran-HGF, respectively. The biodegradability results revealed that the Sacran/KGF-HGF degraded for about 41.29% in trichloroacetic acid (TCA) and 22.92% in TrypLE™ (recombinant enzyme) solutions. In addition, KGF improved the degradability of Sacran/KGF-HGF in both solutions. Interestingly, the Sacran/KGF-HGF, which was applied on wound site, considerably improved the wound healing ability of Sacran-HGF at 6, 9 and 12 d in alloxan-induced diabetic mice model, compared to control (non-treated).Conclusion: These results suggest that KGF has the potential to promote the chronic wound healing ability of Sacran-HGF.

Regenerative therapy with keratinocyte growth factor (KGF) is a novel therapeutic approach for treatment of chronic wounds. However, KGF cannot be used directly to the wound site due to its physicochemical instability. In previous study, sacran, a natural megamolecular polysaccharide, showed potential properties as a biomaterial for hydrogel film in wound healing. In this study, we fabricated sacran hydrogel film containing KGF (Sac/KGF-HF) and evaluated the effects of Sac/KGF-HF on fibroblasts migration and reepithelialization process. We successfully prepared a homogenous and-amorphous Sac/KGF-HF by a casting method. In addition, Sac/KGF-HF had a high swelling ratio and flexibility. Sac/KGF-HF promoted a migration process of NIH3T3 cells and improved wound healing ability in mice with a percentage of wound closure reaching 90.4% at 9 d. Interestingly, the addition of KGF in Sac-HF considerably increased the number of epithelial cells compared to control, which is important in the re-epithelialization process. It could be concluded that KGF in Sac-HF has the potential for promoting Sac-HF abilities in wound healing process.

Muntingia calabura is one of the plants employed to produce herbal-based treatments. Muntingia calabura leaves are traditionally used as an alternative medicine due to their secondary metabolites. The maceration method extracted Muntingia calabura leaves using 96% ethanol solvent for 3 x 24 hours. The fractionation process was carried out using a separating funnel method with different polarities, such as n-hexane, ethyl acetate, and ethanol-water. Thin-layer chromatography (TLC) was used to confirm the phytochemical screening. TLC conditions under UV light 254 and 366 nm using solvents, such as chloroform: methanol (alkaloids), butanol: acetic acid: water (flavonoids), chloroform:methanol: water (saponins), and chloroform: methanol (phenolic). The phytochemical screening results of extracts and Muntingia calabura fractions contained secondary metabolites, such as alkaloids, flavonoids, tannins, saponins, and phenolics. TLC results showed that n-hexane fraction contained flavonoid and saponin compounds; ethyl acetate fraction contained alkaloids, flavonoids, saponins and phenolic compounds; and ethanol-water fraction contained alkaloids, flavonoids, saponins, and phenolics. Muntingia calabura leaves indicated the potential as herbal medicine by containing secondary metabolites.

COVID-19 is an epidemic that is being experienced by almost all countries in the world. Several things that can be done to suppress the spread of this disease are frequent hand washing, wearing masks, maintaining distance, avoiding crowds and limiting mobility. However, this regulation also raises some problems. For example, regulations regarding social restrictions that can trigger stress. Increasing the frequency of hand washing can trigger hand dermatitis. Based on these problems, the researchers are interested in developing aromatherapy hand cream products. This product has a dual function, which are as a hand moisturizer and as an aromatherapy product. The purpose of this study was to analyze the physical characteristics and consumer preference level of hand cream with different essential oils, namely 1% eucalyptus oil (HCE) and 1% sweet orange oil (HCO). Parameters of physical characteristics observed included organoleptic, pH, and spreadability. The results of the organoleptic test were analyzed descriptively. Meanwhile, the results of the pH and spreadability tests were analyzed using Independent Sample T-test statistical analysis. In the hedonic test, the parameters assessed were odor, color, and texture. Hedonic test data were analyzed using Mann-Whitney statistical analysis. Based on the physical characteristic test, it was concluded that HCE and HCO have the same visual appearance and spreadability. However, HCE and HCO have different odor and pH. Based on the hedonic test, it was concluded that the scent of HCO is preferred by the panelists than the scent of HCE.

Probiotik sebagai mikroorganisme hidup dalam jumlah tertentu mampu memberikan manfaat kesehatan pada kulit. Penggunaan probiotik di beberapa negara Asia berkembang pesat, mulai dari penggunaan probiotik dalam industri pangan hingga industri kosmetik. Studi klinis terbaru melaporkan bahwa probiotik mampu mengobati eksim atopik, dermatitis atopik, menyembuhkan luka bakar, menghilangkan bekas luka, mengobati jerawat, mencegah penuaan dini, dan meregenerasi kulit. Artikel ini bertujuan untuk membahas manfaat probiotik pada kulit sehingga dapat dikembangkan sebagai zat aktif pada produk kosmetik. Metode yang digunakan dalam penyusunan artikel yaitu study literatur berbagai jurnal internasioanal yang diakses dari situs Google Scholar dan ScienceDirect. Hasil review artikel menunjukkan probiotik yang paling banyak digunakan dalam produk kosmetik yaitu Enterococcus, Lactobacillus, dan Bifidobacterium. Probiotik memiliki aktivitas sebagai antibakteri, antijerawat, antioksidan, mencegah kerusakan kulit akibat radiasi UV, menurunkan sensitivitas kulit, mengurangi ketombe dan mampu menghasilkan asam hialuronat untuk meningkatkan kelembaban kulit dan mengurangi munculnya garis-garis halus dan kerutan. Dari review artikel ini dapat disimpulkan bahwa probiotik dapat digunakan sebagai ingredients pada produk kosmetik.
