Abstract

High accumulation of lipids in hepatocytes can trigger an increase in the production of radical compounds, leading to fatty liver disease. This condition induces histological changes in the liver, especially in hepatocytes, and affects the surrounding structures. Mahogany seeds have the potential to act as a hypolipidemic agent in treating fatty liver. Mahogany seeds are known to contain phytochemical compounds which act as antioxidants. This study aimed to determine liver histopathology of rats by inducing high-fat diet after giving mahogany seeds ethanol extract which was observed through the percentage of steatosis, hepatocyte diameter, and hepatosomatic index. This study involved thirty male Sprague Dawley rats, divided into 6 groups: P0 (given commercial feed), P1 (given high-fat diet), P2 (given high-fat diet and simvastatin at a dose of 8 mg/200 g BW), P3, P4, and P5 (given high-fat diet and mahogany seeds ethanol extract at a dose of 14, 28, and 56 mg/200 g BW). The results showed that the hepatosomatic index among all treatment groups did not differ significantly; however, the percentage of steatosis and hepatocyte diameter in the groups given mahogany seeds ethanol extract significantly differed from the group given only high-fat feed. Based on these results, it can be concluded that mahogany seed ethanol extract can maintain the histological structure of the liver in male Sprague Dawley rats with fatty liver. Keywords: hepatocyte, hepatosomatic index, high-fat diet, mahogany seeds, steatosis

Abstract

Wound healing in hyperglycemia patients is still a challenge in the medical field. Bioactive compounds of binahong leaf extract can support the wound healing process. Nanoencapsulation of the extract can avoid oxidation and optimize drug delivery to target tissues. This study aimed to analyze the effect of nanochitosan encapsulated binahong extract ointment (NEBE/Oint) on the percentage of wound healing, angiogenesis, collagen density, and epithelial thickness in hyperglycemic rats. This study used 80 mg/kg streptozotocin-induced hyperglycemia rats injured in the back area. Rats were divided into P0 (0,9% NaCl), P1 (10% povidone-iodine ointment (PI/Oint)), P2 (10% NEBE/Oint), P3 (20% NEBE/Oint), P4 (30% NEBE/Oint). Phytochemical screening of binahong leaves extract showed positive results for flavonoids, alkaloids, saponins, and tannins. NEBE particle size was 169 nm with a size distribution of 0.2 and a zeta potential value of -40,2 mV. The results showed NEBE ointment had a significant effect when compared with negative control on wound healing hyperglycemic rats. The conclusion is that nanochitosan drug delivery has the potential as an alternative wound treatment. The novelty of this study is the use of nanochitosan to accelerate wound healing in hyperglycemic rats. The results of this study are expected to become a reference for new wound-healing methods in the medical field.

Abstract

Cigarettes are tobacco products intended to be burned and inhaled, including white cigarettes, which use natural tobacco without additional ingredients, resulting in lower nicotine and tar levels. However, excessive smoking still poses a risk of organ damage, particularly to the liver, due to the presence of toxic chemical compounds in tobacco smoke. This study aimed to analyze the effects of white cigarette smoke exposure on the liver histopathology of white rats (Rattus norvegicus). A completely randomized design was used with 24 male rats (±200 g) divided into four groups: control (P0), exposure to one cigarette/day (P1), two cigarettes/day (P2), and three cigarettes/day (P3), each with six replications. The observed parameters included liver weight, hepatosomatic index, and the diameters of hepatic lobules, central veins, and hepatocytes. Data were analyzed using ANOVA followed by Duncan’s test at a 5% significance level. The results showed that exposure to white cigarette smoke had a negative effect on the diameter of the hepatic lobules, but did not have a negative effect on the other parameters. This study contributes to scientific understanding of the hepatotoxic effects of white cigarette smoke and provides a foundation for further research on the molecular mechanisms of liver injury caused by toxic compounds in tobacco smoke.
