Abstract

BACKGROUND: Biosilica derived from Indonesian marine sponge Melophlus sarasinorum and Xestospongia testudinaria is one of the biomaterials that can be developed together with synthetic polymer as a composite. Poly E-caprolactone (PCL) used as a composite role as an osteoconductive material together with biosilica and also tailored the slow rate of degradation in the body. This study aimed to create a biocompatible biosilica-based scaffold and supports osteogenic differentiation of human Wharton's Jelly mesenchymal stem cell (hWJ-MSCs).METHODS: Biosilica was extracted from M. sarasinorum and X. testudinaria with the acid digestion method. Scaffold was prepared using the salt leaching method. The composite scaffolds were made from seven different biosilica extract and PCL. All of the scaffolds were tested for the cell morphology, Fourier-transform infrared spectroscopy (FTIR), immunocytochemistry, and cytotoxicity.RESULTS: Composite scaffolds of 50% M. sarasinorum and X. testudinaria increased the cell viability and supported the cell growth within 14 days, whereas the osteogenic differentiation can be seen by the presence of collagen type 1 in day 12 based on immunocytochemistry result.CONCLUSION: The biosilica scaffolds from PCL+50% M. sarasinorum and PCL+50% X. testudinaria were promising 3D scaffolds for potential application in bone tissue engineering. In conclusion, this study shows evidence for the osteogenic differentiation of hWJ-MSC, which might be developed for bone tissue engineering.KEYWORDS: sponge, biosilica, scaffold, osteogenesis, stem cell

Abstract

BACKGROUND: Cholestasis caused by obstruction of the common bile duct and may developed gut-derived sepsis due to reactive oxygen species (ROS) accumulation. Ursodeoxycholic acid (UDCA) and glutathione are widely known for their antioxidant properties, that might be beneficial against ROS. However, the effects of UDCA-glutathione combination against ROS have not been well elucidated in previous studies. Thus, this study was conducted to evaluate tumor necrosis factor (TNF)-α level and height of terminal ileal mucosal villus after UDCA-glutathione administration in cholestasis rat model.METHODS: Twenty-eight male Sprague Dawley rats were randomly grouped into four treatment groups, each group consisted of seven rats that had previously undergone bile duct ligation. Three groups received treatment of UDCA-glutathione combination on stratified dose, while the other one only received UDCA. Each treatment was given for 21 days. Ileal samples were collected from the rats and stained with mouse anti TNF-a antibody and hematoxylin-eosin (HE). Immunohistochemistry and histopathological examination were done using microscope and then calculated with ImageJ.RESULTS: The combination of UDCA and glutathione treatment decreased the TNF-α expression (p<0.05) compared to UDCA only group, particularly in group that received 20 mg UDCA and 15 mg glutathione supplementation (p<0.05) and group that received 30 mg UDCA and 20 mg glutathione supplementation (p<0.05). The height of the mucosa villous was higher in the UDCA-glutathione combination groups for all the three dosage variations given (p<0.05) compared to UDCA only group.CONCLUSION: UDCA-glutathione combination downregulates TNF-α expression and improves ileum mucosal villus height in cholestasis.KEYWORDS: cholestasis, glutathione, intestinal villus height, TNF-α, UDCA

Abstract

BACKGROUND: The interaction of carbamazepine (CBZ) and acetaminophen (APAP) could result in hepatic failure and mortality. This study was conducted to analyzed the potential of rosemary ethanol extract (REE) or coenzyme Q10 (CoQ10) to alleviate the interactions between CBZ and APAP.METHODS: Fourty-eight adult male rats were treated differently based on the assigned groups. Oxidative stress parameters, including malondialdehyde (MDA), glutathione (GSH), glutathione peroxidase (GPx), superoxide dismutase (SOD), catalase, and glutathione S-transferase (GST), and the expression levels of CYP3A4, CYP2E1, IL-6, TNF-α, and IL-1B in the liver were estimated. In addition, the histopathology of liver was examined and the plasma clearance rate of CBZ and APAP was estimated.RESULTS: Combination of CBZ and APAP significantly elevated alanine aminotransferase (ALT) activity and hepatic MDA, and reduced the activities of GPx, GST, and GSH level in liver. The gene expression of CYP3A4 and CYP2E1 was upregulated by CBZ and CoQ10, respectively. The expression of IL-6 has decreased in the groups treated with CBZ alone or in combination with APAP. TNF-α expression was significantly downregulated in the groups treated with CBZ, APAP, REE, CoQ10, or combination CBZ and APAP. The liver from CBZ and APAP combination group showed centrolobular degeneration and necrosis. REE and CoQ10 were able to alleviate most of these detrimental effects. The combined administration of CBZ and APAP extended the plasma clearance time of APAP and CBZ from 6 to 24 and from 9 to 24 hours, respectively.CONCLUSION: REE and CoQ10 alleviated the detrimental effects of the combination of CBZ and APAP through enhancing the cellular antioxidant milieu, induction of metabolizing enzymes, reduction of the plasma half-life of APAP and CBZ preventing their accumulation and potential interaction.KEYWORDS: acetaminophen, antioxidants, carbamazepine, CoQ10, CYP3A4, CYP2E1, glutathione, lipid peroxidation, rosemary
