Abstract

Penelitian ini bertujuan mengetahui pengaruh penambahan vitamin E dan mineral Zn terhadap kualitas semen kambing Boer. Rancangan yang digunakan adalah rancangan acak lengkap (RAL) dengan empat perlakuan, yakni P0= tanpa penambahan vitamin E maupun mineral Zn; P1= pemberian vitamin E 50 IU/ekor/hari; P2= pemberian mineral Zn 25 mg/ekor/hari; P3= pemberian vitamin E 50 IU/ekor/hari dan mineral Zn 25 mg/ekor/hari. Penelitian menggunakan 12 ekor kambing berumur 3 tahun, masing-masing perlakuan menggunakan 3 ekor kambing. Data yang diperoleh dianalisis menggunakan analisis ragam dan dilanjutkan dengan uji beda nyata terkecil (BNT). Hasil penelitian menunjukkan bahwa pemberian vitamin E dan mineral Zn serta kombinasi keduanya tidak memengaruhi volume semen kambing Boer, tetapi berpengaruh terhadap motilitas dan persentase spermatozoa abnormal (P0,05) dan terhadap persentase spermatozoa hidup (P0,01). Pemberian mineral Zn dan campurannya dengan vitamin E mampu meningkatkan kualitas spermatozoa kambing Boer.

Abstract

This study aimed to evaluate anticancer activity and apoptosis induction of ethanolic extract of Arcalengisia flava (AF) roots on HepG2 cancer cell lines. The AF roots were extracted by maceration using ethanol 80%. MTT assay method was used to evaluate the anticancer activity and the proliferation of HepG2 cells. Flow cytometry method was used to assess the induction of HepG2 cells apoptosis. This study showed that the IC50 of AF ethanol extract against HepG2 cells was 109.14 μg/ml. With IC50 treatment, the apoptosis assay showed a significant decrease in intact cells (80.10±1.7%) and a significant increase in early apoptosis (7.9±0.7%) and late apoptosis cells of HepG2 cancer cells (4.9±0.35%) compared to control cells. Moreover, the proliferation of HepG2 cells was declined significantly in 48 and 72 hours after treatment with IC50 (77.5±5.76% and 64.3±5.37%, respectively) and 2xIC50 of the extract (75.9±1.79% and 70.5±4.27%, respectively). This research suggests that the ethanolic extract of AF roots can potentially be used for hepatocarcinoma treatment.

Abstract

The aim of this study was to observe cortisol levels and liver histopathology of broiler chicken that were treated with black cumin oil (BCO) under heat stress. A total of 15 broiler chickens were used in this study and divided into 5 groups, K- (without treatment), K+ (given heat stress), P1 (given heat stress and 0.56mL BCO/400kg body weight, P2 (given heat stress and 1.11 mL BCO/400 g body weight), and P3 (given heat stress and 2.22 mL BCO/400 g body weight). Heat stress was given for 5 hours with temperature range of 34-35° C for 7 days. Cortisol was measured using the cortisol enzyme-linked immunosorbent assay (ELISA) kit. Liver histopathology was stained with hematoxylin eosin and observed with electron microscope. The data were analyzed using one way analysis of variance (ANOVA). This study found that application of heat stress to broiler chickens increased cortisol levels and induced histopathological changes in the liver. The BCO administration reduced cortisol level significantly (P0.05) in heat-stressed broilers. BCO administration also significantly  reduced (P0.05) the degenerative changes in liver histopathology such as fat degeneration, hemorrhage and necrosis in broiler chickens under heat stress, but did not significantly influence the inflammatory cells infiltration. As conclusion, BCO administration to broiler chickens under heat stress can reduce cortisol levels and minimize histopathological changes in the liver.

Abstract

This study aimed to determine the ability of highly pathogenic avian influenza virus (HPAI) virus subtype H5N1 originated from Indonesia to induce apoptosis in Madin-Darby Canine Kidney (MDCK) cells. Three HPAI virus subtype H5N1 isolates with different genetic characteristic namely A/Bird/Bali1/2011, A/Chicken/East Java/BwiI2/2010 and A/Chicken/West Java/1074/2003, were cultured in MDCK cells. Apoptosis was identified by deoxyribonucleic acid (DNA) fragmentation of infected MDCK cells using Apoptotic DNA Ladder Kit. The results showed that all three HPAI virus isolates used in this study did not able to induce apoptosis in the MDCK cells within 5 to 72 hours post infection.
