Abstract

Background: Oxidative stress reaction can cause liver injury. This process can be prevented by antioxidant activities which can break the destructive chain caused by free radical substances in the liver. Propolis produced by Trigona spp. bee is known to have a high level of antioxidant. The aim of this study was to examine the effect of Trigona spp. bee propolis on liver histological toxicity caused by carbon tetrachloride-induced oxidative stress.Methods:This experimental study was conducted in September 2013 at the Animal Laboratory of Departement of Pharmacology and Therapy, Faculty of Medicine Universitas Padjadjaran. Twenty-four healthy male Wistar rats as objects were adapted for one week and randomly divided into 3 groups. Group I was the control negative, group II was given carbon tetrachloride on day 14, group III was given Trigona spp. bee propolis on day 1-14. On day 14, group III was injected CCl4 intraperitoneally. The quantitative data were statistically analyzed using the one way ANOVA and Tukey test with p value < 0.05.Results: Group I showed the liver contained normal cells, without significant injury of the membrane, round and complete nucleus. The average number of liver cell was 464 ± 9.59281 cells/field; group II underwent necrosis and the average of the cells was 146 ± 7.56885 cells/field; group III showed some normal liver cells, and some necrotic area with the normal liver cells average was 263 ± 14.10860 cells/field. The p-value=0.00.Conclusions: Trigona spp. bee propolis has a hepatoprotective effect against CCl4-induced liver injury histologically. [AMJ.2016;3(3):481–5]DOI: 10.15850/amj.v3n3.861

Abstract

Background: Peptic ulcer disease is commonly found in the community. Nonsteroidal anti-inflammatory drug (NSAID) such as aspirin is one of the predisposing factors to ulcers. According to various studies, plant extracts have been shown to produce promising results in the treatment of peptic ulcers. Xanthone, the active substance contained in the mangosteen pericarp extract has been extensively studied for its role in various diseases. The present study was undertaken to identify the effect of mangosteen pericarp extract on gastric mucosal damage.Methods: This study was carried out from September−November 2014 in the Animal Laboratory of the Department of Pharmacology and Therapy, Faculty of Medicine, Universitas Padjadjaran/Dr. Hasan Sadikin General Hospital, Bandung. Thirty two rats were randomly divided into 2 groups with different treatments and were induced by aspirin. Histologic studies were conducted to determine the score of gastric mucosal damage. The parameters used were Wattimena’s criteria for damage of gastric mucosa. Data was analyzed using Chi Square test and the outcome was measured in relative risk.Results: The study revealed a significant association between pretreatment with mangosteen pericarp extract and incidence of gastric mucosal damage induced by aspirin (p < 0.05). Calculation with a modified 2 × 2 table revealed a relative risk of 0.625.Conclusions: Rats pretreated with mangosteen pericarp extract exhibit less gastric mucosal damage, in experimentally aspirin-induced ulcer.

Abstract

Background: Gentamicin is one of the most common antibiotics related to nephrotoxicity. It has been proposed that the nephrotoxicity is associated with the generation of the reactive oxygen species. Thymoquinone, an active compound of Nigella sativa, shows to have an antioxidant property. The study aims to identify the possible nephroprotective action of Nigella sativa infusion against gentamicin-induced kidney damaged in mice.Methods:This experimental study was carried out in the Department of Cell Biology Laboratory, Universitas Padjadjaran, Bandung from 10th November 2012 to 14th December 2012. There were four groups, each consisting of  6 mice. Group I (control negative), group II (gentamicin 100 mg/kg), group III (3.9 mg Nigella sativa infusion+gentamicin 100mg/kg) and group IV (7.8 mg Nigella sativa infusion+gentamicin 100mg/kg). The kidneys were evaluated histopathologically by light microscope. The percentage average number of normal proximal tubules in group I and the percentage average number of proximal tubules damaged in group II, III and IV were measured.Results: The results showed the percentage average number of the proximal tubules damaged in group II, III and IV were 14.53%, 7.49% and 3.94% respectively. Significant differences were observed between group II and III, group II and IV, and group III and IV.Conclusion:Nigella sativa infusion protects against gentamicin-induced kidney damage in mice.Keywords: gentamicin, kidney, Nigella sativa infusion  Infusa Nigella sativa sebagai Antioksidan Terhadap Kerusakan Ginjal padaTikus yang Diinduksi Gentamisin   LatarBelakang: Gentamisin adalah salah satu antibiotik yang paling sering dihubungkan dengan nefrotoksisitas.

Abstract

Background: Helicobacter pylori and non-steroid anti-inflammatory drugs are the major causes of peptic ulcer in the world. Indonesian native stingless bee species, Trigona spp., produces propolis that might be effective to protect mucosal damage. The aim of the study was to determine the protective effect of Trigona spp. propolis on aspirin-induced gastric mucosal damage in rats.Methods: This experimental study was conducted from September–November 2013 at Animal Laboratory of Department of Pharmacology and Therapy Faculty of Medicine Universitas Padjadjaran. Healthy male Wistar rats (n=24) aged 2–3 months old and weighed 200–250 grams were randomly divided into three groups. The first group was control negative, the second group was given 100 mg/kg body weight of aspirin, and the third group was given 200 mg/kg body weight of Trigona spp. propolis, one hour before administration of 100 mg/kg body weight of aspirin. After two weeks of treatment, rats were sacrificed by laparotomy to obtain gastric tissues, followed by processing for the paraffin section for histopathological analysis. The grade of gastric mucosal damage was determined under a light microscope. Data were then compared between groups using the Mann-Whitney test.Results: Oral administration of aspirin-induced gastric mucosal damage ranging from grade 0 to grade IV; whereas administration of propolis showed a reduction of gastric mucosal damage’s grade when compared to the aspirin group (p<0.05).Conclusions: Trigona spp. propolis has a protective effect on aspirin-induced gastric mucosal damage. Further study is encouraged to study an optimal dose of aspirin after propolis administration.

Abstract

Background: Snakebite is considered a global health issue, especially in the Southeast Asian region. However, data regarding snakebite cases in Indonesia are still very limited. This study aimed to explore the venomous snakebite cases and the serum anti bisa ular (SABU) antivenom effect in treating venomous snakebite caused by other than the snake species indicated in currently available SABU antivenom formulas.Methods: The analytical descriptive method with a cross-sectional study design was conducted in 2021 using a total sampling from the medical records of 63 patients diagnosed with snakebite at Dr. Hasan Sadikin General Hospital Bandung from 2015 to 2019. Characteristics of patients, clinical manifestation, and correlation between snakes species and outcomes after treatment with or without administration of SABU antivenom were collected.Results: Out of 63 patients, males (79%) were predominant with an average age of 39 years. Fifty-six patients arrived at the Emergency Room less than 24 hours after the occurrence (89%). Most cases were categorized as grade 2 (41.%) where the upper extremities were commonly bitten the body area (64%). Edema (83%) was the most common manifestation. There was no correlation between snake antivenom administered to a specific snake species and the stated outcome (p=0.053), meaning that SABU antivenom might be an effective alternative to treat more types of snakebites.Conclusions: Snakebites are most common in males, attack the upper extremities, categorized as grade 2 with edema. Administration of SABU antivenom provides the similar outcome compared to the group caused by the Javan spitting cobra, Banded krait, and Malayan pit viper.
