Abstract

The tyrosine kinase receptor RET, which is the protein product of the RET gene, is involved in the development of the mammalian nervous system that causes Hirschsprung’s disease (HSCR). RETs are cell surface molecules that are expressed in cells derived from the neural crest. The purpose of this study was to investigate the polymorphism of the RET gene in HSCR in the Yogyakarta population. Genomic DNA was extracted from surgically removed bowel tissues of 54 unrelated HSCR patients. Exon 2 of the RET gene was amplified by polymerase chain reaction (PCR) and analyzed by restriction fragment length polymorphism (RFLP). Molecular results were compared with clinical performance of Hirschsprung patients. RET polymorphism was detected in exon 2 in all of the 54 Indonesian HSCR patients. The allelic distribution of the c135GàA polymorphism in the RET exon 2 indicated that the A allele was more frequent in patients than in control individuals (chi-square test, p= 0.001). Thus the RET variant allele A is over-represented in patients affected with the HSCR phenotype. Polymorphism of exon 2 of the RET gene was found in sporadic Hirschsprung’s disease in the Yogyakarta population, which suggests that the RET gene plays important roles in the pathogenesis of HSCR.

Abstract

BACKGROUNDHypertension is the most prevalent chronic disease and has an impact on one billion people. Production of superoxide radicals and endothelial dysfunction are involved in hypertension. Scurrula atropurpurea (BL.) Dans. is a tea plant parasite. This study aimed to evaluate the role of Scurrula atropurpurea (BL.)Dans. on nitric oxide (NO) as a marker of endothelial dysfunction and malondialdehyde (MDA) as a marker of oxidative stress in hypertensive rats.METHODSThis study subjected rats to deoxycorticosterone acetate (DOCA)-induced hypertension. The experimental groups consisting of the control group and 3 hypertension groups receiving Scurulla  tropurpurea extract at a dosage of 50; 100; and 200 mg/KgBW. Scavenging activity of Scurrula atropurpurea (BL.) extract was analyzed by the 1,1-diphenyl-2-picrylhydrazyl (DPPH) method. The levels of arterial nitric oxide (NO) and pulmonary  malondialdehyde (MDA) were analyzed by spectrophotometry. ANOVA and a post hoc test were applied to find the difference of arterial NO and pulmonary MDA levels between groups.RESULTSThe level of arterial NO was significantly decreased in the hypertension groups as compared with the control group, while the level of pulmonary MDA was significantly increased (p<0.05). Scurulla atropurpurea significantly increases the NO level at a dosage of 200 mg/KgBW, compared with the hypertension groups (p<0.001). Scurulla atropurpurea significantly decreases pulmonary MDA level at a dosage of 100 and 200 mg/KgBW compared with the hypertension groups (p<0.05).CONCLUSIONScurulla atropurpurea extract increases arterial NO and decreases pulmonary MDA in hypertensive rats, thus playing an important role in endothelial dysfunction and oxidative stress.

Abstract

Preterm delivery is one of the causes of high perinatal morbidity and mortality. Matrix metalloproteinase 9 (MMP-9) is important for extracellular matrix (ECM) remodeling and may cause preterm labor and premature rupture of membranes (PROM). Tumor necrosis factor-α (TNF-α) as a pro-inflammatory cytokine plays a role in stimulating uterine activity and cervical ripening by degrading the ECM of the amniotic membranes through MMP-9. This study aimed to determine differences between MMP-9 and TNF-α expression of the membranes in preterm delivery with premature rupture of membranes (PPROM) and without PROM.MethodsAn analytic observational study with cross-sectional approach was conducted in 24 subjects, who were divided into 2 groups, with 12 subjects in the preterm delivery group with PROM and 12 subjects in the preterm delivery group without PROM. The expression of MMP-9 and TNF-α in the amniotic membrane was determined by immunohistochemistry. Data were analyzed using the t test.ResultsMMP-9 expression in the amniotic membrane of preterm delivery subjects with PROM (8.6 ± 3.1%/field) differed significantly with that of preterm delivery subjects without PROM (5.5 ± 2.3 %/ field) (p=0.001). TNF-α expression in the amniotic membrane of preterm delivery subjects with PROM (8.0 ±3.0%/field) also differed significantly with that of preterm delivery subjects without PROM (3,3 ± 1.5%/field) (p=0.000).ConclusionExpression of MMP-9 and TNF-α was higher in the amniotic membrane of preterm delivery subjects with PROM than in preterm delivery subjects without PROM and can thus be used as predictor to avoid PPROM.

Abstract

Takayasu arteritis is a chronic, inflammatory large vessel arteriopathy that primarily affects the aorta, its main branches, and the pulmonary arteries. Fibrosis and thickening of the arterial wall often occur in later stages, resulting in a cerebrovascular accident. A 20-year old man presented with ischemic stroke of young adults due to Takayasu’s arteritis, from which he had been suffering since childhood (age 10). Physical examination showed an abdominal aortic aneurysm, renal artery stenosis, leading to renovascular hypertension, and asymmetrical blood pressure. Aneurysm of abdominal aorta was diagnosed by panaorto-arteriography. Subsequently ischemic stroke of young adults developed, because the arteritis had led to stenosis of the left anterior and middle cerebral arteries, with renovascular hypertension as additional risk factor. On this patient a percutaneous transluminal angioplasty operation of the right renal artery was performed, and it is intended to do an extra-intracranial arterial bypass. Preventive treatment is necessary to stem the extension of the arteritis to other blood vessels.

Abstract

One important aspect that will determine the quality of human life is sex life. Therefore sexual activity may be used in the assessment of the quality of life. Erectile dysfunction (ED) is the inability to continuously achieve or maintain a penile erection quality so as to achieve a satisfying sexual relationship. The aim of this study was to determine the relationship between ED and quality of life in the male elderly. A cross-sectional study was carried out on males aged 60 years and over in West Cilandak village, South Jakarta. The presence of ED was evaluated by means of the International Index of Erectile Function (IIEF) and quality of life with the Short Form Health Survey (SF-36). One-way analysis of variance (ANOVA) was used to compare the mean difference of QOL by erectile dysfunction category. The correlation between the total ED score  and QOL was analyzed using the Pearson correlation analysis. Subjects included 199 elderly male patients, with mean age of 66.7 years (age range 60-81 years), among whom 80.5% presented with ED. The results of ANOVA analysis showed that ED affects quality of life total score (p=0.000), with a significant difference in the vitality (p=0.029), physical function  (p=0.048), and role emotional subscales (p=0.011). ED is a highly prevalent among elderly males and impairs the overall quality of life, The SF-36 is applicable and suitable for evaluation of quality of life.

Abstract

BACKGROUND Imbalance between oxidative processes and antioxidant defenses has been considered to play a role in cataractogenesis, particularly in diabetes patients. Superoxide dismutase (SOD) is an important precursor for oxidative stress in the human lens, and its activity is mainly dependent on the copper and zinc levels in the body. The aim of this study was to compare erythrocyte SOD, erythrocyte zinc and total serum testosterone levels in male patients with early senile nuclear cataract and evaluate the correlations between the parameters in all subjects. METHODS A community-based study of cross-sectional design was conducted at Cilandak District Primary Health Center where 52 adult and 17 elderly men with early senile nuclear cataract were chosen as the study subjects. Erythrocyte SOD, erythrocyte zinc, serum testosterone, and fasting blood glucose (FBG) levels were measured in all subjects. Nuclear cataract stage was assessed with the Pentacam® instrument (Oculus, Germany). Independent Student t test and Pearson’s correlation were used to analyze the results. RESULTS Erythrocyte SOD level was significantly decreased in elderly men compared to adult men (p=0.014). Erythrocyte zinc, serum testosterone and FBG did not differ significantly in adult and elderly males (at p=0.304; p=0.145;and p=0.376, respectively). Erythrocyte SOD activity was significantly associated with erythrocyte zinc level (r=0.486; p=0.048). CONCLUSIONS Lower erythrocyte SOD activity was found in elderly males than in adult males with early nuclear cataract. There was a relationship between erythrocyte SOD and erythrocyte zinc level in elderly males with early nuclear cataract.

Abstract

In March and early April 2009, while much of the world was focusing on the threat of avian influenza originating in Asia, intelligence gathering systems were also extracting evidence of an epidemic of acute respiratory infections in Mexico and southern California. Although the exact sequence of events is uncertain, the Centers for Disease Control and Prevention (CDC) had confirmed the presence of a novel reassortment of Influenza A strain H1N1 from avian, swine, and human strains. On 25 April 2009, The World Health Organization (WHO) declared the swine flu outbreak in North America a public health emergency of international concern. On 29 April 2009, the International Health Regulations emergency committee recommended a change from WHO pandemic influenza phase 4 to phase 5. This means that WHO views a pandemic as imminent. WHO and the CDC have confirmed that the new swine flu virus is transmitted between humans.

Abstract

BackgroundA catechin isolate from the green tea clone GMB 4, which shows antioxidant activity, may be a candidate drug for prevention of atherosclerosis. The aim of this study was to analyze the effect of catechin on endothelial nitric oxide synthase (eNOS) and p110 phosphoinositide 3-kinase inhibitor (PI3K) expression and on p38 mitogen activated protein kinase (MAPK) activity in male rats fed a high fat diet.MethodsTwenty five male Wistar rats were divided into the following five groups: rats on standard diet; rats on high fat diet; rats on high fat diet + catechin 3 mg/day; rats on high fat diet + catechin 6 mg/day; and rats on high fat diet + catechin 24 mg/day. eNOS and p110 PI3K expression and p38 MAPK activity were measured by means of ELISA. ResultsHigh fat diet significantly increased eNOS expression, decreased p110 PI3K expression, and increased p38 MAPK activity in male rats, in comparison with standard diet (p<0.05). Administration of 3 mg/day catechin decreased eNOS expression compared to that in the high fat diet group without catechin (p<0.05). The administration of catechin increased p100 PI3K expression to a similar extent as that in the high fat diet groups with catechin 6 mg/day and 24 mg/day. Administration of catechin at all doses decreased p38 MAPK activity to the level of the standard diet group. ConclusionsHigh fat diet increases eNOS expression, decreases PI3K expression, and increases p38 MAPK activity. Administration of catechin decreases eNOS expression, increases PI3K expression, and decreases p38 MAPK activity.

Abstract

BACKGROUNDLead acetate (Pb) inhibits heme biosynthesis through inhibition of δ-aminolevulinic acid dehydrogenase (δ-ALAD), copro porphyrinogenoxidase, and ferro chelatase. Zinc supplementation increases lead-bindingmetallothionein proteins. The purpose of this study was to find evidence that zinc supplementation prior to lead exposure improves heme biosynthesis in ratsMETHODSThis was a randomized post-test only control-group design study involving 28 rats assigned to 4 groups (1 control and 3 treatment groups). The treatment groups were supplemented with zinc at doses of 0.2, 0.4, and0.8 mg daily by gavage for 3 weeks. From week 4 to 13, all groups wereexposed to lead 0.5 g/kg BW/day by gavage. At the end of week 13, δ-ALAD, erythrocyte protoporphyrin (EPP), and heme concentrations were determined by means of ELISA. One-way ANOVA, followed byBonferroni’s test was used to analyse the data.RESULTSMean δ-ALAD concentrations decreased from the control group down totreatment group 3 (0.24 ± 0.20; 0.15 ± 0.15; 0.12 ± 0.11; 0.05 ± 0.06 ng/mean per unit). Mean EPP concentrations decreased from the control group down to treatment group 3 (1.96 ± 0.50; 1.24 ± 0.24; 1.03 ± 0.05; 0.62 ± 0.16 ng/mL). Mean heme concentrations increased from the controlgroup up to treatment group 3 (8.07 ± 2.64; 10.11 ± 2.27; 10.04 ± 1.65;11.41 ± 2.58 μM). ANOVA followed by Bonferroni showed that EPP concentrations differed significantly between the control group and treatment group 3 (p=0.00).CONCLUSIONZinc supplementation prior to lead exposure improves heme biosynthesis in rats exposed to lead.

Abstract

BackgroundSoil-transmitted helminth (STH) infection can cause malnutrition and vice versa, and decrease serum zinc concentrations. No previous studies were found on the effect of STH treatment on serum zinc concentrations in elementary school children. The objective of this study was to evalaute the effect of STH treatment on serum zinc concentration in elementary school children in Jakarta. MethodsA pre-experimental study (one group pre and post) was conducted on 3rd - 5th grade students in one elementary school in North Jakarta. FLOTAC examination was used to determine infection status and STH intensity, while serum zinc concentrations were measured by atomic absorption spectrometry. All children were given albendazole 400 mg for three consecutive days. Stool and blood samples were collected before and three weeks after treatment with albendazole. A paired t test was used to analyze the data. ResultsThe STH prevalence was 63.4%; these were mainly Ascaris lumbricoides and Trichuris trichiura infections. Before treatment, children infected with A.lumbricoides and T.trichiura had significantly higher serum zinc concentrations (p=0.028; p=0.014). After treatment, children with A.lumbricoides had significantly lower serum zinc concentrations (p=0.039), while children with T.trichiura had slightly lower serum zinc concentrations (p=0.659) than before treatment. ConclusionsAlbendazole treatment produces lower serum zinc concentration in elementary school children with A.lumbricoides infections. A profound understanding of the interaction between helminth infections and zinc may assist in guiding integrated and sustainable intervention strategies among affected children throughout the world.
