ABSTRACT Burn wounds remain a serious problem in several countries. The presence of burn wounds might trigger local or in severe cases also triggers systemic response. Immediate treatment is required to prevent further tissue damage. Silver sulfadiazine cream is commonly used as a burn therapy. However, long-time usage might cause negative side effects. Several effective alternatives with better safety are opted, including virgin coconut oil (VCO). Originating from Cocos nucifera, commonly known as the coconut plant, VCO is a product that contains a lot of beneficial substances, such as lauric acid, polyphenol, and alpha-tocopherol. Hydrolyzed VCO can be an alternative to topical drugs in second-degree burns as it increases Vascular Endothelial Growth Factor (VEGF) expression and collagen thickness in the burn wound healing phase. This randomized post-test only with parallel-group experiment was done using Wistar rats induced to a second-degree burn. The effect of 70% and 100% on second-degree burn healing, measured by hydrolyzed VCO on VEGF expression and collagen thickness was observed between 6 and 12 days of therapy. VEGF expression and collagen expression increased higher in groups treated with 70% and 100% hydrolyzed VCO compared with the control group treated with base cream.

Introduction: Depression is a common condition in epilepsy patients, especially temporal lobe epilepsy both before and after epilepsy surgery. However, not many studies have examined the depression status of patients undergoing surgery outside the temporal lobe (extratemporal resection). Differences in levels of depression between temporal lobe epilepsy (TLE) and extra-TLE patients are also not well known, so the effect of surgery on mood disorders in this group of epilepsy patients needs to be further investigated. Aim: This study aims to study whether there are differences in depression rates for TLE and extra-TLE patients in case studies of post-epileptic surgery patients. Method: The design of this study was cross sectional by conducting research on patients with temporal lobe epilepsy (n = 29) and extra temporal epilepsy patients (n = 24) from 1999 to 2019. The study was conducted at the Hospitals in Semarang. Researchers recorded depression levels using the Beck Depression Inventory - II (BDI-II) after the patient had surgery. The collected data will be analyzed using the parametric 2 independent samples t test. Results: 53 patients who were subject were 29 TLE patients (54.7%) and 24 Extra TLE patients (45.3%). TLE patients who had normal BDI-II results were 14 patients (48.3%), mild depression by 6 patients (20.7%), moderate depression by 8 patients (27.6%) and severe depression by 1 patient (3,4%) while the Extra TLE patients showed normal results of 11 patients (45.8%), mild depression of 8 patients (33.3%), moderate depression of 4 patients (16.7%) and severe depression of 1 patient ( 4.2%). 2 independent samples t test showed insignificant results, namely p = 0.831. Conclusion: There are differences of depression level between TLE and Extra TLE cannot be confirmed, because there are many factors such as the duration of epilepsy and seizure frequency that influence patients. Multifactorial explanation for the depression in patients with TLE and extra TLE must be investigated.Keywords: TLE (Temporal Lobe Epilepsy), extra-TLE, Depression

Background: Atherosclerosis is the main cause of ischemic heart disease which leads to death for people aged more than 40 years old. Genistein is an important isoflavone compound which may protect the blood vessels from endothelial injury. This research is to observe the efficacy of genistein rich edamame as a prevention for atherosclerotic abdominal aortic lesions that seen from abdominal aortic thickness and foam cells count. Method: Thirty rats were divided randomly into five groups and treated for 28 days. The negative control group was given food and drink ad libitum. The positive control group was induced for atherosclerosis using adrenaline 0.006 mg / 200 gr BW injected on the first day and then the next day was given egg yolk 5 gr / 200 gr BW on next day for 28 days. All of the treatment groups were induced for atherosclerosis and treated with genistein-rich edamame extract 5 mg / 200 gr BW, edamame extract 38 mg / 200 gr BW and atorvastatin 1.5 mg / 200 grBW. Data were analyzed using One Way ANOVA - post hoc Bonferroni test, Kruskal Wallis - Mann Whitney test, and Pearson correlation test. Results: There were significant differences (p<0,001) in abdominal aortic thickness and foam cells count between positive control group and treatment genistein-rich edamame extract, edamame extract and atorvastatin. There was a significant correlation between the abdominal aortic wall thickness and foam cells count (correlation coefficient value 0,753; p<0,001). Conclusion: The administration of genistein-rich edamame extract can prevent the thickening of abdominal aorta and foam cell formation. Genistein-rich edamame can prevent foam cells formation better than atorvastatin.
