Background: Colorectal malignancies are common, with adenocarcinoma as the most prevalent type. Recently, studies of specific morphology like tumor budding have already started and related with tumor's aggressivity as well as several parameters. This study aims to evaluate the association between tumor budding grade with patient age, sex, tumor location, histological grade, depth of invasion, and nodal status in colorectal adenocarcinoma at Sanglah General Hospital. Methods: This cross-sectional descriptive study used samples of intestinal resection specimens accompanied by Regional Lymph Node (RLN) removal of colorectal adenocarcinoma patients at Sanglah Hospital in 2018-2020. The sampling technique was carried out consecutively, which met the inclusion and exclusion criteria. Data on age, sex, tumor location, histologic grade, depth of invasion, and nodal status were Latar Belakang: Kanker kolorektal merupakan keganasan yang sering ditemukan dengan adenokarsinoma merupakan tipe histopatologi terbanyak. Dewasa ini telah mulai diteliti morfologi spesifik yaitu tumor budding yang dikaitkan dengan agresivitas tumor maupun parameter lainnya. Penelitian ini bertujuan untuk mengetahui hubungan antara tumor budding grade dengan umur pasien, jenis kelamin, lokasi tumor, grade histopatologi, kedalaman invasi, dan status nodal pada adenokarsinoma kolorektal di RSUP Sanglah Denpasar. Metode: Penelitian deskriptif potong lintang ini menggunakan sampel spesimen reseksi usus disertai pengangkatan Kelenjar Getah Bening (KGB) regional pasien adenokarsinoma kolorektal di RSUP Sanglah tahun 2018-2020. Teknik pengambilan sampel

Background: Photoaging increases MMP-1 and damage collagen by forming ROS. The antioxidant compounds in Clitoria ternatea L. have been studied to lower ROS, thus inhibiting the emergence of MMP-1 and preserving the collagen. The study initiated to analyze the Clitoria ternatea L. extract cream 5% effect on inhibiting MMP-1 increase and collagen decrease in female Wistar rat's skin exposed to UV-B. Methods: A randomized post-test-only control group design was conducted on 30 female Wistar rats, aged 8-10 weeks old with 130-150 grams bodyweight. They were assigned to three groups: the untreated group, placebo group, and the Clitoria ternatea L. extract cream 5% group. The last two groups were exposed to UV-B. After  four weeks their skin was examined for MMP-1 levels using ELISA and collagen amount using Picro Sirius Red staining. Results: A comparative analysis showed that the lowest mean levels of MMP-1 was seen in the untreated group (4.64 ± 0.14 ng/ml), followed by the Clitoria ternatea L. extract cream group 5% (5.54 ± 0.21 ng/ml) and placebo group (8.68 ± 0.78 ng/ml). The highest mean of collagen amount was seen in the Clitoria ternatea L. extract cream group 5% (76.12 ± 5.09 %pixel), followed by the untreated group (69.38 ± 3.96 %pixel) and placebo group (30.31±8.06 %pixel). The comparative analysis shows a significant difference between groups (p < 0.05). Conclusion: The Clitoria ternatea L. extract cream 5% has proven to inhibited the increase of MMP-1 levels and decrease of collagen amount in Wistar rats skin exposed to UV-B.
