Abstract

BACKGROUND: The purpose of this research is to understand the secondary metabolites of Momordica charantia L. extract, as well as to disclose the potential of M. charantia extract in the phagocytic activity and capacity of peritoneummacrophages.METHODS: Examination of immunomodulatory effect was done by giving M. charantia ethanol extract on 5 treatment groups, given intra-peritoneally to mice daily. Echinacea extract as positive control and double distilled water as negative control were also given. On the 8th day, mice were infected with Staphylococcus epidermidis. After 30 minutes, peritoneum fluid was obtained to observe the activity and capacity of macrophage cells.RESULTS: The results showed significant phagocytic activity (p<0.05) at a concentration of 1,200 ppm compare to the other groups. Meanwhile the macrophage cell capacity was found statistically insignificant (p>0.05). The highest phagocytic activity was the group treated with 1,200 ppm (62%), significantly higher than other groups.CONCLUSION: The secondary metabolite content of M. charantia is alkaloids, flavonoids, tannins, saponins, and triterpenoids. The 1,200 ppm M. charantia ethanol extract is potential in inducing phagocytic activity and capacity. These results indicate that the M. charantia can be suggested as a natural immunomodulator.KEYWORDS: pare fruit, Momordica charantia L., phagocytosis, macrophage, immunomodulator

Abstract

BACKGROUND: Hypermethylation of RASSF1A and CDKN2A is one of epigenetic factor underlies nasopharyngeal carcinoma (NPC) development. Smoking behavior as an NPC’s risk factor causes aberrant DNA methylation. RASSF1A and CDKN2A promoter hypermethylation from peripheral blood cells correlates with smoking behavior. The use of body fluids including peripheral blood as a specimen for DNA methylation analyzes are widely developed, as less invasive method compared to the use of tissue biopsy. This study aims to observe the association between RASSF1A and CDKN2A methylation in peripheral blood and smoking behavioramong NPC patients.METHODS: Newly diagnosed NPC subjects were recruited from ear-nose-throat (ENT) outpatient clinic of Dr. Sardjito Hospital, Yogyakarta. DNA from buffycoat of 19 smokers and 20 non-smokers NPC’s patients were isolated. Bisulphite modification was applied to 500 ng of the isolated DNA. The methylation status was detected by MSP (methylation-specific polymerase chain reaction (PCR)). The association between smoking status and promoter hypermethylation was analysis using Chi-Square test.RESULTS: MSP analysis of RASSF1A showed that 68.42% smoker and 75% non-smoker NPC’s patients were methylated. MSP analysis of CDKN2A showed that 21.05% smoker and 25% non-smoker NPC’s patients were methylated. There was no association between smoking behavior with RASSF1A and CDKN2A methylation (p>0.05).CONCLUSION: Statistical analysis showed that smoking behavior is not associated with methylation of RASSF1A and CDKN2A among NPC’s patients.KEYWORDS: DNA methylation, CDKN2A, RASSF1A, Nasopharyngeal carcinoma, Smoking

Abstract

BACKGROUND: Acetaminophen, when used at low doses is a safe drug, but at higher doses it induces apoptosis in hepatoma cells. Arcangelisia flava that grows widely in Kalimantan Island, Indonesia, contains berberine which is effective in protecting the liver. This work was aimed to study the effect of A. flava extract on the modulation of caspase-3 in acetaminophen-induced hepatotoxicity.METHODS: Thirty-five Wistar male rats were divided into groups: I the normal control (water); II the negative control (Arabic gum powder or PGA, 2% in suspension); III the positive control (silymarin); IV-VII (A. flava extract 100, 200, 400, and 800 mg/Kg of body weight (BW), respectively) for 14 days. At day 15th, group II-VII were induced with acetaminophen 1000 mg/Kg of BW per oral for 7 days along with the extracts. At day 22nd, the animals were measured for their serum glutamic oxaloacetic transaminase (SGOT), serum glutamic pyruvic transaminase (SGPT) and gamma-glutamyl transferase (GGT), histological examination, and Western blotting.RESULTS: Acetaminophen elevated the SGOT and SGPT (3x compared to normal group), and GGT (5x compared to normal group) of the animals in group II. Pre-treatment with higher doses of A. flava extract (group VI and VII) significantly prevented the biochemical changes induced by acetaminophen. Normal histology of the liver was showed by group I, III, VII, whereas dilated sinusoids, central vein (CV) lesion, and local haemorrage were observed in group II, IV, V and VI. Western blotting showed an inhibition of caspase-3 expression by A. flava extract in dose-dependent manner.CONCLUSION: A. Higher dose A. flava extract shows hepatoprotective activity by preventing the elevation of serum transaminases and transferase levels. Eventually, no damage in the acetaminophen-induced rat’s liver was observed. This plant modulates the expression of caspase 3 protein in dose-dependent manner.KEYWORDS: Arcangelisia sp, caspase-3, berberine, hepatoprotective activity, NSAIDs, yellow root

Abstract

BACKGROUND: Obesity is an important cardiovascular risk factor and associated with low grade inflammation in chronic kidney disease (CKD) patients. This study aims to assess the association between body fat with serum high sensitivity C-reactive protein (hs-CRP) level in CKD patients.METHODS: A cross-sectional study was performed in 71 CKD patients. Anthropometric measurements included body weight, height, body mass index (BMI), body fat percentage (BFP), skinfold thickness (SKF) of triceps and biceps were performed by trained physician. BFP was calculated using Kwok’s Formula and hs-CRP was measured by Particle enhanced Turbidimetry.RESULTS: The averaged BMI of our subjects was 25.8±4.4. There was no significant difference in BMI between pre-dialysis and hemodialysis CKD patients. Positive correlation was found between BFP and hs-CRP (r=0.266; p<0.05), while there was no significant correlation between BMI and hs-CRP.CONCLUSION: Body fat percentage was associated with hs-CRP. Hence, it will be more beneficial to assess nutritional status in CKD using BFP rather than BMI alone since it was demonstrated to correlate with hs-CRP in our studyKEYWORDS: CKD, obesity, inflammation, body fat, hs-CRP

Abstract

BACKGROUND: The leaf and fruit of Psidium guajava L. are potential for neutraceutical beverage especially for antidiabetic drink. The aims of this study were to determine the antidiabetic activity of aqueous extract of leaf (LE) and fruit (FE) from P. guajava.METHODS: Both extracts were investigated for their inhibitory effect on α-glucosidase activity in vitro. Their antioxidant activities were measured by 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical scavenging, ferrous ion chelating, reducing power and phosphomolybdate methods.RESULTS: The IC50 of LE, FEandacarbose as a positive control were 5.67, 428.00 and 823.99 μg/mL, respectively. The enzyme kinetic analysis indicated that LE inhibited α-glucosidase in a competitive inhibition type, similar to that of acarbose. Both extracts showed antioxidant activities, with LE showed stronger activities than FE in all methods. In DPPH method, IC50 of LE and FE were 74.77 and 843.84 μg/mL respectively, compared to 53.24 and 21.36 μg/mL for reference antioxidants butylated hydroxytoluene (BHT) and ascorbic acid (AA), respectively. In ferrous ion chelating activity, the IC50 were 147.07 and 2105.05 μg/mL for LE and FE, whereas ethylenediaminetetraacetic acid (EDTA) as a control sample was 66.50 μg/mL. In reducing power and phosphomolybdate methods, at different concentrations, the activities of LE, FE, and standard compounds showed the following order: AA > BHT > LE > FE.CONCLUSION: LE from P. guajava exhibited excellent inhibitory activity against α-glucosidase. In addition, LE had better antioxidant acivities than FE. This study can recommend the aqueous extract from P. guajava as a promising candidate for neutraceutical drink for prediabetic and diabetic patients.KEYWORDS: antioxidant, aqueous extract, α-glucosidase inhibition, guava, Psidium guajava L.

Abstract

BACKGROUND: Atherosclerosis is a leading cause of vascular disease worldwide. During the past several decades, landmark discoveries in the field of vascular biology have evolved our understanding of the biology of blood vessels and the pathobiology of local and systemic vascular disease states and have led to novel disease-modifying therapies for patients. This review is made to understand the molecular mechanism of atherosclerosis for these future therapies.CONTENT: Advances in molecular biology and -omics technologies have facilitated in vitro and in vivo studies which revealed that blood vessels regulate their own redox milieu, metabolism, mechanical environment, and phenotype, in part, through complex interactions between cellular components of the blood vessel wall and circulating factors. Dysregulation of these carefully orchestrated homeostatic interactions has also been implicated as the mechanism by which risk factors for cardiopulmonary vascular disease lead to vascular dysfunction, structural remodeling and, ultimately, adverse clinical events.SUMMARY: Atherosclerosis is a heterogeneous disease, despite a common initiating event of apoB-lipoproteins. Despite of acute thrombotic complications, an adequate resolution response is mounted, where efferocytosis prevents plaque necrosis and a reparative scarring response (the fibrous cap) prevents plaque disruption. However, a small percentage of developing atherosclerotic lesions cannot maintain an adequate resolution response, which leading to the formation of clinically dangerous plaques that can trigger acute lumenal thrombosis and tissue ischemia and infarction.KEYWORDS: atherosclerosis, oxidative stress, inflammation, efferocytosis, foam cells, thrombosis

Abstract

BACKGROUND: Lack of appetite in young children leads to growing incidences of physical and mental growth disorders. Supplementation of certain micronutrients can increase appetite and improve nutritional status. This study aims to analyze the effects of zinc and iron supplementation on appetite, nutritional status and intelligence quotient (IQ) in young children.METHODS: An experimental study withrandomized control group pre/post-test design was conducted in Semarang, Indonesia. A total of 68 children were divided into four groups. The first group was the control group, which was given a placebo; the second group was given a zinc supplement at 10 mg/day; the third group was given an iron supplement at 7.5 mg/day; andthe fourth group was given zinc and iron for three months. Appetite was assessed based on eating frequency and energy intake. Nutritional status was assessed by weight per age (W/A) and height per age (H/A) z score. IQ score was assessed based on Wechsler Preschool and Primary Scale of Intelligence (WPPSI).RESULTS: Before intervention, low zinc intake was observed in 27.7% of the subjects and low iron intake was observed in 58.5% of them. After intervention, appetite in the second and fourth groups increased. W/A z score increased in the second and third groups. IQ score increased in the third group. No significant effect on H/A z score was observed in all groups.CONCLUSION: Supplementation of zinc and iron for three months had a positive effect on appetite, body weight and IQ score but no significant effect on body height.KEYWORDS: appetite, zinc, iron, growth

Abstract

BACKGROUND: Diabetes Mellitus (DM) is a heterogeneous group of disorders characterized by increasing blood glucose levels caused by insufficiency of insulin hormone production and activities. There are significant increases in DM case every year in Indonesia, as a consequent, alternative and better drug is needed to be developed. One of the plants that were often used as traditional medicine for DM in Indonesia was Muntingia carabula L. (kersen) leaf. The aim of this research was to evaluate the antidiabetes activity of M. carabula leaves.METHODS: This study was conducted in vivo by evaluating the antidiabetic activity of M. carabula leaf water extract on two animal models, those are insulin deficiency and insulin resistant model animal. The insulin deficiency animal model was developed by aloxan administration at dose of 50 mg/Kg body weight (bw) intravenously. While the insulin resistance animal model was developed by lipid emulsion administration at dose of 0.42 mL/20 grams bw orally. Both groups were randomly devided into 6 groups, which are negative control group, positive control group, standard drug group (glybenclamide 0.65 mg/Kg bw or  metformin 135 mg/Kg bw), and extract groups at dose of 100, 200 and 400 mg/Kg bw. Parameters which were evaluated are fasting blood glucose (FBG) levels for insulin deficiency models and values of constant of insulin tolerance (KITT) for insulin resistant models.RESULTS: In insulin deficient model group, administration of glibenclamide lower the FBG by 43%, furthermore, the extract of M. calabura at doses of 100, 200 and 400 mg/Kg bw also lower the FBG by 13%, 22% and 29%, subsequently. In insulin resistant models, metformin increased the value of KITT from less than 0.5 to 2.91, and administration of the extract at doses of 400, 200 and 100 mg/Kg bw also increased the KITT value to 2.31, 1.57, 1.13, respectively.CONCLUSION: The conclusion was M. carabula leaves water extract with dose of 400 mg/Kg bw had the antidiabetic activities with mechanisms to lower blood glucose level, regenerate pancreatic β cells, and increase insulin sensitivity.KEYWORDS: diabetes mellitus, kersen leaves, Muntingia calabura L., insulin deficiency, insulin resistance

Abstract

BACKGROUND: Caffeic acid inhibits osteoclastogenesis by downregulating expression of Cathepsin K and Nuclear Factor of Activated T cells (NFATc)1, as well as inhibiting activity of Nuclear Factor kB (NFkB). Meanwhile TNF Receptor-associated Factor (TRAF)6 was not influenced by caffeic acid. In order to investigate further caffeic acid's mechanism in inhibiting osteoclastogenesis, regulation of caffeic acid on p38 Mitogen-activated Protein Kinase (MAPK) was investigated.METHODS: RAW-D cells were pretreated with/without caffeic acid and treated with/without 20 ng/mL RANKL and 1 ng/mL TNFα for 0.2, 1, 6, and 12 hour. Tartrate Resistant Acid Phosphatase (TRAP) staining was performed. Then, western blot analysis was performed to detect p38 MAPK and phosphorylated-p38 MAPK. Resulted protein bands were quantified and statistically analyzed.RESULTS: Under induction of 20 ng/mL RANKL and 1 ng/mL TNF-α, RAW-D cells were successfully differentiated into TRAP+ osteoclast-like polynuclear cells. Under treatment of 20 ng/mL of RANKL and 1 ng/mL of TNF-a for 0.2 or 1 hour, significant (p=0,000, T test) increment of phosphorylated p38 MAPK was observed as compared with control. Pretreatment of 10 μg/mL caffeic acid significantly (p=0.000, T test) suppressed the 20 ng/mL of RANKL and 1 ng/mL of TNF-a-induced phosphorylation of p38 MAPK.CONCLUSION: RANKL and TNF-a are potent osteoclastogenesis inductors in RAW-D cells, meanwhile caffeic acid could inhibit the RANKL and TNFa-induced osteoclastogenesis through p38 MAPK.KEYWORDS: caffeic acid, osteoclastogenesis, RANKL, TNF-a, p38, MAPK, RAW-D cells
