Zinc oxide-turmeric extract dressing has been proven to have anti-inflammatory properties, but its effectivity in the reepithelialization process is still unknown. This study aimed to determine the effect of a wound dressing consisting of zinc oxide and turmeric extract on wound reepithelialization by assessing the expression of cytokeratin 14 (CK14), epidermal growth factor receptor (EGFR), and epithelial cadherin (E-cadherin). Materials and Methods: A total of 40 Wistar rats were randomized into four control and four treatment groups (n=5 per group). On day 1, a square-shaped full-thickness skin excision measuring 6×6 mm in size was created in the dorsal thoracic area of the rats, and the wounds were either dressed with a combination of zinc oxide and ...

Aggrecan is chondrogenic differentiation marker which has a significant role in the early stage of GMSCs' osteogenic differentiation. This study aimed to analyze the expression of Aggrecan post PRF administration on the osteogenic differentiation in vitro. This research is a true experimental study using the post-test only control group design with a simple random sampling. GMSCs were isolated from the lower gingival tissue of healthy male Wistar rats (Rattus novergicus) (n=4), weighted around 250 g, a month old, then cultured for 2 weeks and passaged for 4-5 days. GMSCs in the passage 3-5 were cultured in five M24 plates (N=54; n=6/group) for 7 days, 14 days, and 21 days in three different culture mediums, they were negative control group which included α Modified Eagle Medium; positive control group which contained High Glucose-Dulbecco's Modified Eagle Medium (DMEM-HG) combined with osteogenic medium; and at last, treatment group which were DMEM-HG combined with both osteogenic medium and PRF. A one-way Analysis of Variance (ANOVA) test (P<0.05) was performed. The treatment group showed the highest Aggrecan expression of 16.15±2.15 on the 7 th day. The lowest Aggrecan expression with a value of 3.67±0.76 on the 21 th day occurred in the negative control group. There was a significant difference of Aggrecan expression between groups (P<0.05). PRF administration unexpectedly stimulates Aggrecan expression of GMSCs during the osteogenic differentiation that useful to accelerate the bone remodeling or neo-cartilage formation.

Secondary brain injury is a complex cascade that causes brain cell apoptosis. Curcumin is a natural product that has neuroprotective properties. AIM: This study aimed to investigate the effect of curcumin toward heat shock protein 70 (HSP 70) expression against the expression apoptosis marker (apoptosis-inducing factor [AIF], caspase-3, and TUNEL assay) in brain tissue after TBI. METHODS: Thirty-three Sprague Dawley rats were randomized into three treatment groups, that is, sham-operated controls, closed head trauma (CHT), and CHT with curcumin extract (treatment group). In the treatment group, curcumin was given 500 mg/kg per oral for 7 days, then brain tissues were investigated (marker AIF, caspase-3, TUNEL assay, and HSP 70) through immunohistochemistry. Statistical test using one-way ANOVA test and Tukey honestly significant difference as post hoc test. RESULTS: ...

Damage of these proteins by inflammation may alter digestion, absorption and barrier function. Probiotic has been widely known in maintaining gut health. However, the molecular mechanism of Lactobacillus plantarum IS-2056 probiotic in repairing intestinal brush border is not well defined. Therefore, current study was conducted by investigating the Galectin-4 and Myosin-1a expressions in a rodent model.METHODS: Male Wistar rats were induced with/without lipopolysaccharide (LPS) and treated with/without L. plantarum IS-2056 probiotic. On the seventh day, duodenum, jejunum, and ileum were collected and analyzed with western blot and immunohistochemistry for Galectin-4 and Myosin-1a expressions.RESULTS: Rats administrated with L. plantarum IS-2056 probiotic showed significant increase of Galectin-4 and Myosin-1a expressions in duodenum, jejunum, and ileum compared to...
