Abstract

BACKGROUND: Acetaminophen, when used at low doses is a safe drug, but at higher doses it induces apoptosis in hepatoma cells. Arcangelisia flava that grows widely in Kalimantan Island, Indonesia, contains berberine which is effective in protecting the liver. This work was aimed to study the effect of A. flava extract on the modulation of caspase-3 in acetaminophen-induced hepatotoxicity.METHODS: Thirty-five Wistar male rats were divided into groups: I the normal control (water); II the negative control (Arabic gum powder or PGA, 2% in suspension); III the positive control (silymarin); IV-VII (A. flava extract 100, 200, 400, and 800 mg/Kg of body weight (BW), respectively) for 14 days. At day 15th, group II-VII were induced with acetaminophen 1000 mg/Kg of BW per oral for 7 days along with the extracts. At day 22nd, the animals were measured for their serum glutamic oxaloacetic transaminase (SGOT), serum glutamic pyruvic transaminase (SGPT) and gamma-glutamyl transferase (GGT), histological examination, and Western blotting.RESULTS: Acetaminophen elevated the SGOT and SGPT (3x compared to normal group), and GGT (5x compared to normal group) of the animals in group II. Pre-treatment with higher doses of A. flava extract (group VI and VII) significantly prevented the biochemical changes induced by acetaminophen. Normal histology of the liver was showed by group I, III, VII, whereas dilated sinusoids, central vein (CV) lesion, and local haemorrage were observed in group II, IV, V and VI. Western blotting showed an inhibition of caspase-3 expression by A. flava extract in dose-dependent manner.CONCLUSION: A. Higher dose A. flava extract shows hepatoprotective activity by preventing the elevation of serum transaminases and transferase levels. Eventually, no damage in the acetaminophen-induced rat’s liver was observed. This plant modulates the expression of caspase 3 protein in dose-dependent manner.KEYWORDS: Arcangelisia sp, caspase-3, berberine, hepatoprotective activity, NSAIDs, yellow root

Abstract

BACKGROUND: Central obesity is known as a risk factor for type 2 diabetes mellitus (T2DM). Its development is influenced by many factors such as a progressive failure of pancreatic beta cell function. The beta cells increase their function to secret insulin along T2DM development to compensate before it becomes exhausted. Zinc (Zn) plays a crucial role in beta cell function and insulin secretion. The majority of Zn in serum are bound to protein which is not readily available interact with cells. The free Zn in serum has been suggested as being more representative than total Zn in beta cell function. This research aimed to investigate the correlation between serum free Zn and homeostasis model assessment for beta cell function (HOMA-B) and to predict the pancreatic beta cell function in the development of T2DM.METHODS: This study was designed as an observational with a cross-sectional approach. The subjects were centrally obese men aged 30-50 years and who had met the inclusion and exclusion criteria from the screening tests. Control subjects were lean men without T2DM. Serum free Zn and serum total Zn were measured by using inductively coupled plasma-mass spectrometry (ICP-MS).RESULTS: There was positive correlation between serum free Zn and HOMA-B (R=0.361, p-value<0.001) but there was no correlation between serum total Zn and HOMA-B (R=-0.062, p-value=0.563). This study found that if the concentration of serum free Zn >1.7 ug/dL in central obese men was suggested as an excessive function of pancreatic beta cell and as an early warning before its exhausted.CONCLUSION: This study suggested that serum free Zn had a correlation with beta cell function and had a predictive ability for beta cell excessive function before its exhausted.KEYWORDS: Type 2 diabetes mellitus, HOMA-B, serum free zinc, central obesity
