Abstract

Background: Hypercholesterolemia is one of the most common diseases in the world, with cholesterol levels exceeding normal levels. Hypercholesterolemia can cause various systemic disorders in the body. One of the signs is by decreasing HDL (High-Density Lipoprotein) cholesterol levels. Dragon fruit peel contains many ingredients, such as vitamin B3 (niacin), vitamin C, flavonoids, anthocyanins, and other minerals that can affect the increase in HDL production and reduce total cholesterol levels. Purpose: To know the effect of red dragon fruit peel extract (Hylocereus polyrhizus)on increasing levels of High-Density Lipoprotein (HDL) in male rats (Rattus norvegicus) hypercholesterolemia. Methods: Male rats were made hypercholesterolemic using a mixture of lard (3 ml) and egg yolk (1 g) for 14 days orally. 20 hypercholesterolemic male rats were further divided into 5 treatment groups and given dragon fruit peel extract therapy with different treatments, namely T0 negative control (CMC-Na 1% + aquadest), T1 positive control (Simvastatin 0.0013 mg/200 g BW), T2, T3 and T4 (each 100, 150, 200 mg/kg BW red dragon fruit peel extract) for 14 days orally.  Blood serum was taken on day 36 and tested in the laboratory using a chemical analyzer machine; then the data were analyzed using the univariant multiple way one-way ANOVA statistical test with a significant difference (p>0.05). Results: The P4 treatment group has an effective dose (200 mg/kg BW) to increase high-density lipoprotein (HDL) levels, while the P3 treatment group (dose 150 mg/kg BW) is less effective but can still have an effect. Conclusion: This research showed that red dragon fruit peel extract could increase HDL (High-Density Lipoprotein) cholesterol levels with an effective 200 mg/kg BW dose.

Abstract

Background: Cigarettes are tobacco products processed with or without additives and are known to contain addictive substances that pose serious health risks to individuals and the public. Inhaled cigarette smoke directly stimulates the activation of macrophage cells in the respiratory tract. Among the affected cells, type II alveolar cells which produce pulmonary surfactant to reduce alveolar surface tension are particularly vulnerable to smoke-induced damage. Purpose:  This study aimed to compare the effects of conventional cigarette smoke and e-cigarette vapor exposure on the number of alveolar macrophages and type II alveolar cells in male mice (Mus musculus). Method: A total of 28 male mice were randomly divided into seven groups. The control group (C) was exposed to ambient air only. Groups A1, A2, and A3 were exposed to 1, 2, and 3 conventional cigarettes per day, respectively, while groups B1, B2, and B3 were exposed to 0.7 mL, 1.3 mL, and 2 mL of e-liquid vapor per day, respectively. All exposures were conducted for 36 consecutive days. Results: A significant difference (p<0.05) was observed in the number of alveolar macrophages among groups C, A1, A2 , A3 , B2 , and B3 , whereas no significant difference was found between A1 and B1. The number of type II alveolar cells significantly differed (p < 0.05) across all groups: C, A1, A2, A3, B1, B2, and B3. Conclusion: Both conventional cigarette smoke and e-cigarette vapor increase alveolar macrophage counts and reduce type II alveolar cell numbers compared to controls. Although both exposures pose health risks, e-cigarette vapor appears to cause milder pulmonary effects than conventional cigarette smoke.
