Abstract

Efek Antimikroba Ekstrak Kulit Jeruk Nipis (Citrus aurantifolia) terhadap Salmonella typhi secara In Vitro. Demam tifoid merupakan infeksi akut saluran pencernaan yang disebabkan oleh yaitu Salmonella typhi yang berada pada urutan kedua di antara penyakit usus setelah gastroenteritis. Peningkatan resistensi Salmonella terhadap antimikroba salah satunya kloramfenikol sudah mulai tinggi, sehingga menimbulkan masalah dalam terapi. Kulit jeruk nipis diduga memiliki efek antimikroba karena mengandung minyak atsiri, flavonoid, tanin, saponin, fenol dan alkaloid. Tujuan penelitian adalah untuk membuktikan efek ekstrak kulit jeruk nipis (Citrus aurantifolia) terhadap pertumbuhan bakteri Salmonella typhi. Penelitian ini menggunakan true eksperimental post test only control. Konsentrasi ekstrak kulit jeruk nipis yang digunakan adalah 100%, 50%, 25%, 12,5%, 6,25%, 3,125%, 1,56%, 0,78%, 0,39%, 0%. Analisa data menggunakan one way ANOVA, Korelasi, Regresi, Kadar Hambat Minimum, Kadar Bunuh Minimum. Signifikan 0,000 (P<0,05) pada uji one way ANOVA menunjukkan adanya perbedaan bermakna antar perlakuan pada jumlah koloni. Semakin tinggi ekstrak kulit jeruk nipis, maka semakin sedikit koloni bakteri Salmonella typhi (r= -0,586). Pemberian konsentrasi ekstrak kulit jeruk nipis berpengaruh terhadap penurunan jumlah koloni bakteri Salmonella typhi (R2=0,34). Hasil penelitian KHM didapatkan pada konsentrasi 12,5%, dan KBM pada konsentrasi 6,25%. Ekstrak kulit jeruk nipis memiliki efek antimikroba terhadap Salmonella typhi.

Abstract

Introduction. One of the sexually transmitted diseases is syphilis which is caused by the bacterium Treponema pallidum. Patients with syphilis can experience severe systemic symptoms and can cause disability. However, in latent syphilis the initial symptoms are minimal or even asymptomatic, so that undetected syphilis sufferers can still escape and can carry out blood donation activities. To meet the demand and need for blood in Denpasar City, the Indonesian Red Cross Blood Donor Unit Denpasar City conducted blood donation activities. However, due to the ongoing Covid 19 world pandemic, including Indonesia, the activities of mobile blood donor units are limited. Providing safe blood is the duty of the blood donor unit. Screening test is a way to detect the presence of Transmitted Infection Through Blood Transfusion (IMLTD). The techniques used are Enzyme-linked Immunoserbent Assay (ELISA) and Chemiluminescence Immunoassay (CLIA). Methods. This research is a retrospective descriptive type by taking secondary data from the screening laboratory of the Denpasar City PMI blood donor unit for the period May-December 2021. Results. There were 21 blood samples with reactive syphilis results from May to August which were performed using the ELISA method with a total of 831 donor bags. A total of 28 blood samples from 1,338 bags that were donated showed reactive results from September to December using the CLIA method. Keywords: Syphilis, ELISA, CLIA, blood donation, prevalence

Abstract

BackgroundPolycystic ovary syndrome (PCOS) can cause significant morbidity through fertility disorders and most often found in the productive age. Recent research suggests that oxidative stress plays an important role in the pathogenesis of PCOS. Astaxanthin (AST) has broad protective effects, particularly in the regulation of antioxidant and anti-inflammatory activity. The objective of this systematic review and meta-analysis was to evaluate the efficacy of AST supplementation on PCOS management. MethodsA systematic literature search was conducted in PubMed, Scopus, Science Direct, and Cochrane Library from January 2020 to March 2025. Randomized controlled trials (RCTs) assessing astaxanthin supplementation in adult women with PCOS were included. Outcomes of interest were malondialdehyde (MDA), superoxide dismutase (SOD), and total antioxidant capacity (TAC). Data were analyzed using Review Manager (RevMan) version 5.4.1. Pooled effects were calculated as mean differences (MDs) with 95% confidence intervals (CIs).  ResultsFour RCTs involving 194 participants were included. Astaxanthin supplementation significantly reduced MDA levels (MD −0.670; 95% CI −1.070 to −0.270; p = 0.001; I² = 93%) and significantly increased TAC levels (MD 0.030; 95% CI 0.000 to 0.060; p = 0.030; I² = 76%). No significant effect was observed on SOD levels (MD 0.025; 95% CI −0.850 to 1.350; p = 0.660; I² = 57%). The overall risk of bias across included studies was low. ConclusionThis systematic review shows that AST supplementation significantly reduced lipid peroxidation in women with PCOS. These findings suggest that AST may serve as potential adjuvant antioxidant therapy in PCOS management.
