Abstract: Cayenne pepper (Capsicum frustescens L ) is commonly in daily food. This study aimed to determine the effect of cayenne pepper to histopathological changes in gaster of Wistar rats induced by aspirin. This was an experimental study. Subjects were Wistar rats consisted of 5 rats as the negative control and 20 rats as the treatment group. Group A, the negative control group, was untreated; group B was treated with aspirin 21mg/day for 10 days; group C was treated with aspirin 21mg/day for 10 days together with cayenne pepper 84mg once daily; group D was treated with aspirin 21mg/day for 10 days followed by cayenne 84mg twice daily; and group E was treated with aspirin 21mg/day for 10 days and then was untreated for 3 days. The histopathological changes in group C showed a lot of inflammatory cells and erosion of gastric mucosa epithelium compared to group B, D, and E. Group D also showed inflammatory cells but no erosion as in group C. Group E had less inflammatory cells than group B, C, and D. Conclusion: Administration of aspirin 21mg/kg BW for 10 days led to acute gastritis in Wistar rat. Administration of aspirin together with cayenne 84mg/day led to acute gastritis and erosion of gastric mucosa epithelium. However, administration of cayenne pepper 168mg/day after aspirin led to acute gastritis without erosionKeywords: pepper, gaster, aspirinAbstrak : Cabe Rawit (Capsicum frustescens L.) banyak dijumpai dalam makanan sehari-hari. Penelitian ini bertujuan untuk mengetahui pengaruh pemberian cabe rawit terhadap gambaran histopatologik lambung tikus wistar yang diinduksi aspirin. Jenis penelitian ialah eksprimental. Subjek penelitian ialah tikus wistar, yang dibagi atas: 5 ekor untuk kontrol negatif dan 20 ekor untuk perlakuan. Kelompok A (kontrol negatif) tidak diberi perlakuan; kelompok B diberikan aspirin 21mg/hari selama 10 hari; kelompok C diberikan aspirin 21mg/hari selama 10 hari bersama cabe rawit 84mg sekali sehari; kelompok D diberikan aspirin 21mg/hari selama 10 hari kemudian dilanjutkan pemberian cabe rawit 84mg selama 3 hari 2 kali sehari; dan kelompok E diberikan aspirin 21mg/hari selama 10 hari kemudian tidak diberi perlakuan selama 3 hari. Hasil penelitian menunjukkan bahwa pada kelompok C terlihat banyak sel-sel radang disertai erosi epitel mukosa lambung dibanding dengan kelompok B, D, dan E. Pada kelompok D pemberian aspirin dilanjutkan dengan cabe rawit dosis 2 kali sehari masih terdapat sel-sel radang tetapi tidak terjadi erosi seperti pada kelompok C. Kelompok E memiliki sel-sel radang yang lebih sedikit dibandingkan kelompok B, C, dan D. Simpulan: Pemberian aspirin 21mg/hari selama 10 hari menyebabkan gastritis akut pada tikus wistar. Pemberian aspirin bersama cabe rawit 84mg/hari menyebabkan gastritis akut erosi sedangkan pemberian cabe rawit 168mg/hari setelah diberi aspirin menyebabkan gastritis akut tanpa erosi.Kata kunci: cabe rawit, lambung, aspirin

AbstractChronic exposure to environmental ultraviolet radiation elicits deleterious photoaging changes and histopathological damage to the skin. In addition to cosmetic surgical procedures, over-the-counter products described as cosmeceuticals are widely used by a large segment of globally aging populations to partially reverse changes induced by photoaging. Many such products are rarely examined in the laboratory to examine their ameliorative properties and microscopic effects on various skin compartments. The hairless mouse is a popular animal model widely used over the last few decades by researchers to compare cosmeceuticals about their properties to combat or reverse cutaneous photoaging changes. In the present experiment, five cosmeceuticals were topically administered to the dorsal skin over 2 weeks in the nonirradiated mice, and skin samples were analyzed for dermal histopathological changes. Histomorphometric procedures were employed to generate quantitative data on skin sections prepared with immunohistochemistry and staining technics, and the data statistically examined. Among the five agents tested, glycolic acid and retinoic acid produced striking changes, while vitamin C, estrogen, and soy product resulted in less remarkable responses. These quantitative data will be useful for further photoaging studies with these cosmeceuticals.

This study was designed to isolate and identify the type of moulds and theirpercentage of distribution with pathological study of highly moulds isolated from(130)samples were included in this study with divided into (30)samples driedmilk,(30).samples baby food ,(30)samples raw milk , (40) samples dairy products .The results revealed the percentage of infection according to total count ofisolation in raw milk were 100 % dairy product 65 %. The most common fungiisolated from raw milk were Asp.niger of 16.2 % Asp. fumigatus of 15 % Asp.flavusof 13.7 % Pencillium spp. 12.5 % . From dairy products were isolated withpercentage of Asp. Fumigatus 34.9% Geotrichum spp . of 23 % ,Asp. nager of 11.5% . Pathological study was carried out to investigate the clinical signs with grosslyand Histopathological changes inoculated with most pathogenic moulds Asp.fumigatus (30)male white swiss mice were used in this study and divided into fourgroups . The first group were injected I/P with 0.2 ml of Asp. fumigatus containing1X105 spores / ml , 4th group (control)given orally 0.2 ml of PBs.Two mice fromeach treated groups and one from each control group were scarified on week (1,2,3,4).the clinical manifestation of the 1st group were at 2nd week showed dyspnea .Mouldisolated from blood and internal organs at third week , with no isolation from 3rdgroup. The Histopathological observations showed presence of degeneration ,necrosis and diffused granuloma in liver, lung , spleen , kidney and hemorrhage withthrombosis in brain and intestine .
