Abstract

Abstrak Sindroma metabolik yang ditandai dengan abdominal obesity, resistensi insulin, dislipidemia, perubahan tekanan darah, dan obesitas, prevalensinya semakin meningkat setiap tahun, serta disinyalir sebagai penyebab tingginya penyakit diabetes mellitus tipe 2, penyakit kardiovaslular, dan kematian, baik di negara maju maupun berkembang. Penelitian ini bertujuan untuk mengetahui efek dari pemberian diet tinggi karbohidrat dibandingkan dengan diet tinggi lemak terhadap kadar glukosa darah  dan kepadatan sel beta pankreas tikus Rattus novergicus strain wistar. Kadar glukosa darah diukur dengan menggunakan metode Glukose Oksidase (GOD-PAP); kepadatan sel Sel-β pankreas dihitung jumlahnya menggunakan mikroskop elektron dalam 20 lapang pandang dengan perbesaran 1000 x. Diet tinggi karbohidrat dan diet tinggi lemak diberikan secara isokalori selama 12 minggu, dengan komposisi: diet tinggi karbohidrat (80,57%; 14% protein; dan 5,41% lemak); diet tinggi lemak (55,63% karbohidrat; 14,25% protein; dan 30,10% lemak). Kadar glukosa darah puasa berbeda signifikan antar kelompok perlakuan (p=0.000); rerata kadar glukosa darah puasa darah tertinggi terdapat pada kelompok (P2) 293.57 mg/dl. Kepadatan sel beta pankreas berbeda signifikan antar kelompok perlakuan (p=0.000); rerata kepadatan sel beta pankreas terkecil  terdapat pada kelompok (P2) 45,06 mm2. Diet tinggi karbohidrat dan diet tinggi lemak, keduanya menstimulasi perubahan kadar glukosa darah dan mengurangi kepadatan sel beta pankreas pada tikus wistar jantan. Kata Kunci: diet tinggi karbohidrat, diet tinggi lemak, glukosa darah, kepadatan sel beta pankreas  AbstractThe metabolic syndrome includes the clustering of abdominal obesity, insulin resistance, elevated blood pressure, and obesity associated with the increasing risk of diabetes mellitus, cardiovascular diseases, and death both in less developed and developed countries in the world. The prevalence of metabolic syndrome increasES every year. The aim of this study was to assess blood glucose level using Glucose Oksidase (GOD-PAP) and beta cell pancreas density using microscope.  Blood glucose concentration and beta cell pancreas density were compared in rats fed isocalorically a high carbohydrate diet for 12 w (80,57% carbohydrate, 14% protein, and 5.41% fat) or a high fat diet for 12 w (55,63% carbohydrate; 14,25% protein; and 30,10% fat). At the end of the study, high carbohydrate rats had higher blood glucose concentration than the high fat group (293.57 mg/dl). High carbohydrate and high fat diet both resulted in elevated beta cell pancreas density, but the density was seen lowest in high carbohydrate fed (45,06 mm2). The findings suggest that both high carbohydrate and high fat fed elevated blood glucose concentration and decreased the density of beta cell in rats. Keywords: high carbohydrate diet, high fat diet, blood glucose, beta cell pancreas density

Abstract

Isoflavones (genistein, daidzein) on soybean milk have phytoestrogenic properties. In Asia, the blood phytoestrogen levels can reach 160 ng/ml (80 times higher than Western). This may potentially disrupt endocrine functions regarding its binding with estrogen receptors.. Since the function and distribution of adipose tissues are regulated by estrogen receptors, the reduction of estrogen receptor-α(ERα) results in ectopic fats distribution around visceral tissues, such as the pancreas. Aim: To investigate the impact of subchronic soybean milk and genistein supplementation on pancreatic fatty infiltrations in mice. Methods: The experiment used 35 Sprague dawley male mice under 7 treatment groups within 60 days: negative control with standard rationed food, 3 groups with a variable dose of soybean milk: 100 mg, 200 mg, and 400 mg, and 3 groups with a variable dose of genistein: 0.4 mg, 0.8 mg, and 1.6 mg. Histological measurements on the level of pancreatic fatty infiltrations were conducted after. Analyses used Kruskal-Wallis and post-hoc Mann-Whitney. Results: Medium to a high level of pancreatic fatty infiltrations were found at the control group while there is a decreasing trend on the level of pancreatic fatty infiltrations on groups with soybean milk and subchronic genistein compared with the control group, proportional to higher dosage supplementation. The reduction of pancreatic fatty infiltration levels on groups with soybean milk and subchronic genistein supplementation is not statistically significant compared to control. Conclusion:  Supplementation of soybean milk and subchronic genistein do not significantly reduce the levels of pancreatic fatty infiltrations in Sprague dawley male mice.

Abstract

Endocrine Disrupting compounds (EDCs) are exogenous materials that can interfere with the functions of the endocrine system. Research has demonstrated that pyrethroid compounds affect endocrine function. Transfluthrin belongs to the pyrethroid group that is widely used. These compounds could interact with estrogen receptor α and may increase the expression of estrogen receptor α in rat testis. Aim: to determine the effect of subchronic inhaled transfluthrin exposure on the expression of estrogen receptor α (ERα). Method: we used 35 adult male Wistar rats as experimental animals, which were randomly divided into 5 groups (n=7 per group): negative control group (rats without treatment), solvent control group (rats exposed to n-hexane solvent), and three treatment groups of subchronic inhaled transfluthrin: 0.1 mg/ml (treatment 1),  0.2 mg/ml (treatment 2) and 0.4 mg/ml (treatment 3), treated for 60 days. The immunohistochemical (IHC) staining was used to assess the expression of ERα. Result: there was a tendency for an increase in ERα expression with the addition of a transfluthrin dose. ER α in negative control group, solvent control group, treatment 1 group, treatment 2 group, and treatment 3 group was 16.75 ± 5.01 %; 16.64 ± 13.00 %; 19.31 ± 6.52 %; 25.63 ± 7.08 %, and 28.79 ± 20.31 %; p>0.05, respectively. There was a weak positive correlation between the dose of transfluthrin with ERα expression (r = 0.38, p = 0.025). Conclusion: subchronic inhalation exposure of transfluthrin in rats showed a tendency to increased the expression of ERα (dose-dependent). There is a weak positive correlation between the dose of transfluthrin with ERα expression.                                                                                           Â
