Abstract

One side effect of non-steroidal anti-inflammatory drugs is gastric mucosal irritation, possibly causing gastric ulcers. The aim of this study was to evaluate the protective effect of cincau leaves (Cyclea barbata Miers) on aspirin-induced gastric ulcer in Balb/c mice. Twenty five Balb/c mice (20-30 g, 2-3 months old) were randomly divided into 5 groups. Group I-III were given cincau leave infusion at dosages of 2.5 mg/kg BW, 5 mg/kg BW, and 10 mg/kg BW, respectively, while group IV (positive control) received antacid at a dosage of 20 mg/kg BW, and group V (negative control) one milliliter of distilled water. All interventions were given by the oral route, once daily for seven days. On day 7, the mice were given aspirin (600 mg/kg BW) to induce gastric ulcer. After 30 minutes, all mice were sacrified, and their stomachs examined macroscopically for gastric ulcer, characterized by the presence of ulcer(s) and bleeding. Total ulcer scores were analyzed by one-way Anova to compare between-group protective effect of interventions against aspirin-induced gastric ulcer. Results showed that groups treated with cincau leaf infusion at all dosages experienced a gastric ulcer protective effect. There were significant differences (p=0.002) between treatments, compared to the negative control, but no significant differences (p>0.05) when compared to the positive control. Thus cincau leaves (Cyclea barbata Miers) at dosages of 2.5 mg/kg BW, 5 mg/kg BW, and 10 mg/kg BW, had a protective effect against aspirin-induced gastric ulcer in mice. Higher dosages of cincau leaf infusion have a correspondingly higher gastric ulcer protective power.

Abstract

Intestinal infections with soil-transmitted helminths and protozoa are still prevalent in Indonesia, particularly in urban communities. Transmission of parasitic infections is effected directly or indirectly through objects contaminated with feces, including food, water, fingers and fingernails, indicating the importance of fecal-oral human-to-human transmission. Sidewalk food vendors (SFVs) preparing food for their customers are a potential source of infections with many intestinal helminths and protozoa. Compared to other parts of the hand, the area beneath fingernails harbors the most microorganisms and is most difficult to clean. The objective of this cross-sectional study was to determine the prevalence of intestinal parasites in fingernail dirt of SFVs and to identify the associated factors. This study involved 112 SFVs in the vicinity of Hospital X in Central Jakarta, and used microscopic examination of SFV fingernail dirt for determining species prevalence of intestinal parasites. This study showed that 94 samples out of 112 (83.9%) were positive for intestinal parasites; 60 samples (63.8%) represented single infections and 34 (36.2%) mixed infections. Ascaris lumbricoides eggs were found in 30 (26.8%) samples and Giardia lamblia cysts in 12 (17.89%). The highest prevalence was found in subjects with primary school education, among whom 20 (30.8%) had single infections of A. lumbricoides and 16 (24.6%) mixed infections with A. lumbricoides and Trichuris trichiura. In conclusion, prevalence of intestinal parasites in SFV fingernail dirt is extremely high, with the highest prevalence among less educated SFVs. It is recommended to provide health education and training to all SFVs.

Abstract

Bone remodeling is a physiological process of cortical and trabecular bone reconstruction, with initial bone resorption, by osteoclasts and concurrent bone formation by osteoblasts. Oxidative stress due to coal dust exposure is not only found in the lungs, but also in the circulation or systemically. The aim of this study was to determine the effect of oxidative stress from coal dust exposure on the number of osteoblasts and osteoclasts in rats. In this experimental study, four groups were evaluated: control; coal dust exposure at 6.25 mg/m3 for 28 days; coal dust exposure at 12.5 mg/m3 for 28 days; coal dust exposure at 25 mg/m3 for 28 days (all exposures were given daily for one hour). Circulatory oxidative stress was measured by malondialdehyde level. Osteoblast and osteoclast numbers were counted by light microscopic examination of distal femoral cross-sections stained with hematoxylin eosin. This study showed that malondialdehyde levels were significantly increased in coal dust exposure groups, in comparison with the control group (p<0.05). There were also significantly decreased numbers of osteoblasts (p<0.05) and significantly increased numbers of osteoclasts (p<0.05) numbers in coal dust exposure groups, as compared with the control group. No correlations were found between malondialdehyde levels (oxidative stress) and respective numbers of osteoblasts and osteoclasts in all coal dust exposure groups (p>0.05). Coal dust exposure increased malondialdehyde level and osteoclast numbers, and decreased osteoblast numbers, but no correlation was found between oxidative stress (caused by coal dust exposure) and osteoblast and osteoclast numbers.
