Abstract

Skin is the main target of ultraviolet (UV) ray that result the abnormality of hiperpigmentation. In pathology, hyperpigmentation is caused by an increasing in the amount of melanin. The purpose of this research was to prove the effect of administration of breadfruit leaves extract (Artocarpus altilis) cream prevented the increase of skin melanin in guinea pig (Cavia procellus) exposed to ultraviolet B and to prove the administration of breadfruit leaves extract (Artocarpus altilis) cream have the same effectiveness with 4% hydroquinone cream in preventing the increase of skin melanin in guinea pig (Cavia procellus) exposed to ultraviolet B. This study was a true experimental research using post test only control group design. The subjects were devided into three groups. Group 1 as a control group was treated by UVB exposure and basic cream. Group 2 was treated by UVB and 4% hydroquinone cream. Group 3 was treated by UVB and 3% breadfruit leaves extract cream. There was significant difference within control group compared with group 2 and 3 (p0,05). There was no significant difference within group 2 compared with group 3 (p0,05).The administration of 3% breadfruit leaves extract (Artocarpus altilis) cream prevented the increase of skin melanin in guinea pig (Cavia procellus) exposed to ultraviolet B. The administration of 3% breadfruit leaves extract (Artocarpus altilis) cream had the same effectiveness with 4% hydroquinone cream.

Abstract

Sexual intercourse in adult people is not only related to reproduction,recreation and better relation but also for maintaining good health. Regular andfrequent sexual intercourse has protective role for cardiovascular disease, malignancyand often related with longevity. On the contrary less frequent sexual intercourse isoften correlated to early death and reproductive organ disorders. One main factorwhich involve in any process related to sexual intercourse is nitric oxide. Thisresearch aims to know the declination of total nitrate and nitrite concentration as themain oxidation product of nitric oxide and necrosis of the endothelial and smoothmuscles of corpus cavernosum after three month sexual intercourse abstinence andstress immobilization.By randomized pretest-posttest control group design, the research wasconducted in adult male mice (Mus musculus) which were divided into four groups.each consisted of seven mice. One group as a control and the other three wereexposed to sexual abstinence, immobilization stress and the combination of sexualabstinence and immobilization stress in three months period. The investigation wascarried out to the penile total nitrate and nitrite concentration and the histologicalchanges of the middle part of the penile shaft. To know the degree of lesion then thecalculation of the histologic features was done in five view fields of every preparat.The result was compared to control group.In this research, the mean of total nitrate and nitrite decline and the lowest wasfound in the combine intervention groups with significance level p < 0,005. Thecorpus cavernosum in the intervention groups showed multifocal necrosis onendothelial and smooth muscle cells of corpus cavernosum with picnotic nuclei,irregular form and dark colour. Some muscle cells are lysis. These features werefound in three among seven samples in sexual abstinence group, two among sevensamples in immobilization stress group and in all samples of combined interventiongroup.Conclusions can be drawn from this research are that the sexual abstinence,immobilization stress and the combine interventions decline the nitrate and nitriteconcentrations and induce endothelial and smooth muscle cells necrosis of the copuscavernosum.

Abstract

Caulerpa spp. including seaweed and macro-algae can be found in a large number at Coastal Serangan, Bali-Indonesia. Caulerpa spp was historically used for food and vegetable. However, in our today life, this plant was applied as material for skin care products, especially for UV protection. The aim of this study is to know the active component of caulerpa spp extract and its inhibition of premature skin aging induced by UV-B radiation through collagen expression. This was descriptive and experimental research applying a randomized posttest only control group design. Active component contained in the caulerpa spp extract are carotenoid, vitamin A, C, and E, polyphenols, minerals and amino acids. Topical application of caulerpa spp can suppress the UV-B radiation induced collagen damage. Increased of collagen expression in all groups of caulerpa spp. just as good as astaxanthin group in improving collagen expression and 0.2% of caulerpa spp. extract is the most effective dose in improving collagen expression.

Abstract

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.

Abstract

Abstract: This study was aimed to prove that oral administration of resveratrol could prevent urinary F2-isoprostane elevation in tartrazine-induced male Wistar rats (Rattus norvegicus). This was an experimental study using the pretest-posttest control group design. Subjects were 24 rats (Rattus norvegicus), Wistar strain, healthy, 2-3 months old, weighing 200-220 g, divided into 2 groups with 12 rats each. The first group (P0), the control group, was given a placebo of 2 ml distilled water 2 hours prior to the administration of tartrazine 75 mg/kg body weight. The second group (P1), the treatment group, was given resveratrol of 20 mg/kg 2 hour prior to the administration of tartrazine 75 mg/kg. Rats’ urine was collected before and after treatment for 4 weeks. Level of F2-isoprostane was examined by using an 8-iso-PGF2α enzyme immuno assay kit. The comparative analysis of the pretest groups showed that there was no difference between the average levels of F2-isoprostane in both groups (5.45±0.62 ng/mL in P0 group vs 5.42±0.64 ng/mL in P1 group) (P > 0.05). Meanwhile, after treatment for 4 weeks, the average level of F2-isoprostane in the P0 group was significantly different from the P1 group (6.61±0.93 ng/mL vs 3.79±0.48 ng/mL) (P < 0.01). Analysis of the treatment effect showed a significant increase of F2-isoprostane level in the P0 group, and a significant decrease in the P1 group (P < 0.01).

Saat sebelum dan sesudah perlakuan selama 4 minggu, urin tikus dikoleksi untuk pemeriksaan kadar F2-isoprostan menggunakan 8-iso-PGF2α enzyme immuno assay kit. Analisis komparasi sebelum perlakuan (pretest) menunjukkan rerata kadar F2-isoprostan pada kedua kelompok tidak berbeda nyata (5,45±0,62 ng/mL vs 5,42±0,64 ng/mL) (P > 0,05). Setelah perlakuan selama 4 minggu, rerata kadar F2-isoprostan pada kelompok P0 berbeda nyata dibandingkan kelompok P1 (6,61±0,93 ng/mL vs 3,79±0,48 ng/mL) (P < 0,01). Analisis efek perlakuan menunjukkan terjadi peningkatan kadar F2-isoprostan pada kelompok P0 dan penurunan bermakna pada kelompok P1 (P < 0,01). Simpulan: Pemberian resveratrol oral dapat mencegah peningkatan F2-isoprostan urin tikus (Rattus norvegicus) Wistar jantan yang dipapar tartrazine.Kata kunci: tartrazine, resveratrol, F2-isoprostan, urin

Abstract

Abstract: This study was aimed to evaluate the effectiveness of 20% green tea extract in preventing the increase of melanin in guinea pig skin exposed to UV-B and to compare the effectiveness of this treatment to 4% hydroquinone cream. This was an experimental study with the post-test only control group design. Subjects were four groups; each consisted of 7 male guinea pigs. Group 1, the control group, was exposed to UV-B only. Group 2 was exposed to UV-B and applied with cream based substance. Group 3 was exposed to UV-B and applied with 4% hydroquinone cream. Group 4 was exposed to UV-B and applied with 20% green tea extract. The total UV-B intensity was 390 mJ/cm2 consistently exposed for two weeks. Histopathological slides of the skin tissue were stained with Masson Fontana technique. The total amount of melanin was calculated in percentage of pixel compared to pixel of melanin in total epidermis. The results showed that the highest amount of melanin was in group 1 (24.44%) and the lowest amount of melanin was in group 3 (1.04%) meanwhile the amount of melanin in group 4 (1.34%) was nearly the same with group 3. There were significant differences between group 1 to group 3 and 4 (P < 0.05). There was no significant difference between group 3 and group 4 (P > 0.05). Conclusion: The 20% green tea extract was as effective as 4% hydroquinone cream in inhibiting the increase of melanin in guinea pigs’skin exposed to UV-B.Keywords: green tea extract, melanin, ultraviolet BAbstrak: Penelitian ini bertujuan untuk mengetahui efek pemberian krim ekstrak teh hijau 20% terhadap peningkatan jumlah melanin pada kulit marmut yang dipajan sinar UVB serta membandingkan efektivitasnya dengan krim hidrokuinon 4%. Jenis penelitian ialah eksperimental murni dengan post test only control group design. Subyek penelitian terdiri dari empat kelompok dengan 7 ekor marmut jantan setiap kelompok. Kelompok 1 (kelompok kontrol) diberi pajanan sinar UV-B saja. Kelompok 2 diberi pajanan sinar UV-B dan diolesi krim dasar. Kelompok 3 diberi pajanan sinar UV-B dan krim hidrokuinon 4% sedangkan kelompok 4 diberi pajanan sinar UV-B dan krim ekstrak teh hijau 20%. Dosis total UVB yaitu 390 mJ/cm2 diberikan selama 2 minggu. Sediaan histopatologik jaringan kulit dipulas dengan pewarnaan Masson Fontana. Jumlah melanin dihitung dengan persentase pixel luas area melanin dibandingkan dengan pixel seluruh jaringan epidermis. Hasil penelitian menunjukkan jumlah melanin tertinggi pada kelompok 1 (24,44%) dan terendah pada kelompok 3 (1,04%). Jumlah melanin pada kelompok 4 (1,34%) hampir sama dengan kelompok 3. Terdapat perbedaan bermakna antara kelompok 1 dengan kelompok 3 dan 4 (P < 0,05). Perbandingan antara kelompok 3 dan 4 tidak berbeda bermakna dalam mencegah peningkatan jumlah melanin (P > 0,05). Simpulan: Pemberian krim ekstrak teh hijau 20% sama efektif dengan krim hidrokuinon 4% dalam mencegah peningkatan jumlah melanin kulit marmut yang dipajan sinar UV-B.Kata kunci: krim ekstrak teh hijau, melanin, ultraviolet B
