Exposure to ultraviolet (UV) radiation from the sun may cause photo aging which is characterized by uneven pigmentation and brown spots. Melanin acts to protect the skin against DNA damage due to UV radiation. Sunscreen is a cosmetic preparation that can reflect sunlight, especially in areas with UV wave emulsions. This study aims to determine the effect of black cumin extract cream on the amount of melanin pigment in rat skin exposed to ultraviolet-B rays. An experimental post-test only control group study was conducted from October 2019 - February 2020. A total of 30 rats were divided into 6 groups, namely the KN group (without treatment), P1 (basic cream), P2 (black cumin extract cream 0.25% ), P3 (0.5% cream), P4 (0.75% cream) and KP (Parasol sunscreen cream). Rats in group P4 showed significantly lower amounts of melanin (41.5 ± 10.4) than other groups (KN 41.5, P1 86.0, P2 84.7 and P3 78.7; p <0.05). However, the least amount of melanin pigment was found in the KP group (10.0 ± 1.82). It can be concluded that the topical black cumin extract cream can topically reduce the amount of melanin pigment.

Abstract: Ultraviolet B (UV-B) is a source of free radicals that accelerates aging process, especially in the skin. Repeated exposures to UV-B rays activate enzymes that degrade collagen and inhibit collagen production by inducing the expression of MMP-1. Panax ginseng, a typical herb commonly used in Asia, has antioxidant properties. This study was aimed to prove that Panax ginseng extract cream could prevent collagen degradation and MMP-1 elevation in UVB-exposed Wistar rats (Rattus norvegicus). This was a true experimental study with the posttest only control group design. Subjects were 30 rats (Rattus norvegicus), Wistar strain, male, aged 10-12 weeks, weighing 160-180 g which were divided into 3 groups with 10 rats each: P0 group, without any treatment; P1 group, exposed to UV-B and treated with placebo; and P2 group, exposed to UV-B and treated with Panax ginseng extract cream. After 48 hours of the last radiation for the entire 2 weeks, all rats were anesthetized, and their skin tissues were prepared for histological examination staining with Sirius red. The expresion of MMP-1 and the amount of collagen were observed under 400x magnification of binocular microscopy. The results showed that the average amount of collagen in the P0 group was 69.38±3.96%; in the P1 group was 62.79±3.50%; whereas in the P2 group was 80.55±6.41% (P <0.01). The mean expression of MMP-1 in the P0 group was 15.43±3.13%; in the group P1 was 27.99±5.45%; while in the P2 group was 6.16±2.33% (P <0.01). Conclusion: Panax ginseng extract cream could prevent MMP-1 elevation and collagen degradation in UVB-exposed Wistar rats.Keywords: Panax ginseng, collagen, MMP-1, UVB Abstrak: Ultraviolet B (UV-B) merupakan salah satu sumber radikal bebas yang dapat mempercepat proses penuaan, khususnya penuaan pada kulit.

Photoaging is caused by exposure to sunlight and ultraviolet radiation (UV-B) through the reactive oxygen species (ROS) molecules formation, resulting in decreased levels of collagen. It is characterized by wrinkles, sagging and rough surfaces. Black cumin has been used in medicine due to its high antioxidant potential. The aim of this study is to identify the effect of black cumin cream on collagen levels and hydration of the skin of Rattus norvegicus exposed to ultraviolet-B rays. This is experimental study in which 30 male Wistar strain rats were classified into 6 sub-groups, namely the KN group (without treatment), KP (getting Nivea cream moisturizer), P1 (basic cream ), P2 (black cumin seed extract cream 0.25%), P3 (cream 0.5%) and P4 (cream 0.75%). P4 rat collagen levels increased significantly before and after the intervention (24 ± 2.23 vs 42.6 ± 14.6, p <0.05).Cream with lower concentrations did not provide a significant increase (p> 0.05). P4 rats also showed increased skin hydration (38.6 ± 19.3 to 63.0 ± 4.47 (p <0.05)), and this was not found in other groups. The administration of topical black cumin seed extract 0.75% can inhibit decreased levels of collagen and increase skin tissue hydration.

ABSTRAK Latar Belakang: Kebiasaan masyarakat Indonesia menggunakan obat-obatan yang mudah didapat seperti parasetamol, dimana parasetamol dijual secara bebas akan menyebabkan penyalahgunaannya menjadi lebih besar.Penyalahgunaan ini berakibat timbulnya efek samping  seperti efek hepatotoksik yang menimbulkan kerusakan pada sel-sel hati. Pengendalian efek hepatotoksi didalam tubuh dapat dibantu dengan mengkonsumsi makanan yang mengandung antioksidan. .Ekstrak daun kluwih (Artocarpus camansi) memiliki kandungan antioksidan seperti flavanoid yang diyakini dapat menurunkan aktivitas SGPT dan mengurangi efek toksisitas hepar oleh parasetmol. Tujuan: Tujuan penelitian ini adalah untuk mengetahui pengaruh pemberian ekstrak daun kluwih (Artocarpus camansi) terhadap penurunan aktivitas SGPT  tikus putih (Rattus norvegicus) jantan galur Wistar yang diinduksi parasetamol. Metode: Merupakan post-test only control group mengunakan hewan coba tikus putih jantan galur Wistar yang dikelompokkan menjadi 3 kelompok yaitu kelompok kontrol (-), kelompok kontrol (+), kelompok perlakuan yang mendapat terapi ekstrak daun kluwih (Artocarpus camansi) 500 mg/Kg BB Hasil: Hasil penelitian menunjukkan pemberian ekstrak daun kluwih (Artocarpus camansi) dosis 500 mg/kg/BB/hari pada tikus tidak menurunkan secara bermakna aktivitas SGPT pada kelompok tikus yang diberi parasetamol dosis tinggi ( p=0,401 α=0,05) Kesimpulan: Parasetamol dosis tinggi meningkatkan secara bermakna aktivitas SGPT tikus putih (Rattus norveicus) galur Wistar. Pemberian ekstrak daun kluwih (Artocarpus camansi) pada aktivitas SGPT tikus putih (Rattus norveicus) galur Wistar menurunkan  secara tidak bermakna.
