Abstract

The liver is an organ that has an important role in metabolic and detoxification processes. Alcohol consumption will cause metabolic disorders in the liver and can cause changes in histological structures. Interleukin-6 has a profound role in liver pathology and plays an important role in the body's defense mechanism, and contributes to the manifestation of tissue damage. This study was an experimental study using 20 Rattus norvegicus treated with 25% alcohol, and a normal treatment only given distilled water. Histological observations were carried out on each preparation in 5 fields of view. The hepatotoxicity effect of alcohol was observed based on the presence of cell degeneration and necrosis in histological preparations stained with hematoxylin eosin. IL-6 detection with polymerase chain reaction was analyzed qualitatively using electrophoresis. Based on the statistical test results, the sig. (2 tailed) of 0.00 < 0.05 so that it can be seen that there is a significant difference in histological results between the normal control group without treatment and the group induced by alcohol. The administration of alcoholic beverages with 25% ethanol content in vivo for 21 days causes necrosis and bleeding around the hepatocyte cells. IL-6 overview appeared to be stronger in the group with alcohol-induced drinking, it could indicate that giving alcohol causes a higher inflammatory response. This study provides scientific evidence that alcohol consumption significantly damages the liver. Further research can be conducted to increase the sample size and quantitatively assess IL-6 expression.

Abstract

Background: Tissue preservation is a crucial procedure in pathological studies to maintain cellular and structural integrity, commonly performed through formalin fixation. However, formalin fixation may cause DNA degradation, posing challenges for molecular analysis. Detection of cancer biomarker genes, such as Murine Double Minute 2 (MDM2), can be performed using Polymerase Chain Reaction (PCR), a technique for amplifying specific DNA fragments. Objective: This study aimed to determine the presence of the MDM2 gene in formalin-preserved tissues stored for different periods using PCR. Methods: A descriptive qualitative design with random sampling was employed. The study was conducted at the Anatomical Pathology and Molecular Biology Laboratories of Sekolah Tinggi Ilmu Kesehatan Nasional. Samples included 10 hair and nail tissues as controls, and formalin-fixed tissues stored for 2 days, 1 month, 2 months, and 8 years. DNA isolation was performed using the Geneaid gSYNC™ DNA Extraction Kit. DNA quality was assessed by 1.5% agarose gel electrophoresis, while concentration and purity were measured using a UV-Vis spectrophotometer. DNA concentrations ranged from 320–420 ng/µL, with purity ratios between 0.8 and 1.125. Results: The results showed that the MDM2 gene (178 bp amplicon) was detectable in tissues stored for up to 2 months but was not detected in tissues stored for 8 years. Conclusion: These findings indicate that storage duration affects the success of gene detection in formalin-fixed tissues.

Abstract

Minuman suplemen yang beredar dimasyarakat mengandung senyawa yang dapat menimbulkan adiksi dan hepatotoksik. Honeybee atau madu adalah bahan yang secara empiris dimanfaatkan di masyarakat yang memiliki berbagai kandungan senyawa metabolit sekunder. Penelitian ini berguna untuk melihat gambaran histologi hepar tikus putih yang diberi madu dengan konsentrasi 20% setelah perlakuan minuman berenergi. Hewan uji yang digunakan dalam penelitian sebanyak 25 ekor. Hasil makroskopis memperlihatkan bahwa organ hepar berwarna merah kecoklatan, tekstur kenyal dan ukuran cukup bervariasi namun tidak ada perbedaan antara kelompok. Hasil pengamatan mikroskopis memperlihatkan perubahan sel berupa degenerasi dan nekrosis. Uji ANOVA didapatkan nilai sig yaitu 0,393 (≥ 0,05), yang berarti pemberian madu menunjukkan perbaikan histopatologi hepar tikus putih setelah diberi tambahan minuman berenergi
