Background : Hyperglycemia on diabetes mellitus can cause increasing of free radicals production. Free radicals caused lipid peroxidation reaction by forming malondialdehyde (MDA). β-carotene has antioxidant activity may inhibit the formation of ROS.Objective : To prove the effect of multilevel doses β-carotene 1 mg/kg BW, 20 mg/kg BW and 20 mg/kg BW on alternate days within 30 days orally supplementation on blood glucose level and MDA level on Sprague Dawley male rats induced by streptozotocin (STZ). Methods : Thirty rats were randomly divided into 5 groups: X1=Negative control/diabetic, X2 (STZ 40 mg/kg BW + BC 1 mg/kg BW), X3 (STZ 40 mg/kg BW + BC 10mg/kg BW), X4 (STZ 40 mg/kg BW + BC 20 mg/kg BW), X5 (technic control/non diabetic). β-Carotene supplementation was given by nasogastric tube on alternate days within thirty days. Blood glucose level was measured by GOD-PAP and MDA level by ELISA with TBARS methods. Data was analized using paired t-test, wilcoxon, one way anova and post hoc bonferroni. Results : there was a significant difference of blood glucose level (p = 0,0001) and MDA level (p = 0,0001) after suplementation β-carotene on alternate days within 30 days orally. β-carotene 10 mg/kg BW was the most effective and efficient dose to lowering blood glucose, while 20 mg/kg BW to lowering MDA level. Conclusion : The multilevel doses β-carotene (1 mg/kg BW, 10 mg/kg BW and 20 mg/kg BW) on alternate days within 30 days orally supplementation can decrease blood glucose and MDA level. β-carotene 10 mg/kg BW is the most effecetive and efficient to decrease blood glucose and β-carotene 20 mg/kg BW to decrease MDA level.

Background: Hemoglobin H (HbH) disease is alpha thalassemia characterized by inactivation of three of four α-globin genes due to deletions with or without non-deletional α-thalassemia. Hb Quong Sze (Hb QS) is a very rare non-deletional α-thalassemia in Indonesia caused by a CTGLeu>CCGPronucleotide substitution at codon 125 of α2 globin gene generating highly unstable hemoglobin. Compound heterozygosity for Hb QS and Southeast Asian double α-globin gene deletion (--SEA) result in accumulation of b-globin tetramers, causing hemolytic anemia.Case Report: A 49 years old Chinese Indonesian female was assessed for thalassemia screening. The phenotype of the proband was normal and only mild anemia was noticeable. She experienced blood transfusion five years ago due to a sudden fall of hemoglobin level after malarial infection. Complete blood count found hemoglobin 8.3 g/dL, Mean Corpuscular Volume (MCV) 65.7 fl and Mean Corpuscular Hemoglobin (MCH) 17.1 pg. HbH disease suggested by abundant Hb H inclusion bodies in the red blood cells. Microcapillary hemoglobin electrophoresis result showed HbH 31.8 %, Hb Bart 0.4%, HbA 67.3% and HbA2 0.5%. Molecular studies were carried out using multiplex polymerase chain reaction (PCR) method, and the common a0-thalassemia(--SEA) was detected in one allele. Direct sequencing analysis of the α1 and α2 globin genes revealed Hb QS in the other allele.Conclusion: Non-deletional Hb H disease due to compound heterozygous of  Hb QS with Southeast Asian double α-globin gene deletion (--SEA) has a very low incidence in Indonesia. An advanced molecular analysis should be performed to determine this rare mutation.

BACKGROUND: Inflammation plays an important role in the atherosclerotic process. High-sensitivity C-reactive-protein (hs-CRP) is commonly used as inflammatory biomarker. It is well known that regular physical activity lowers hs-CRP levels, while prolonged exercise induces hs-CRP elevations. However, the relationship of training and exercise characteristics with hs-CRP levels remains not well elucidated. We evaluated baseline and post-exercise hs-CRP levels and its association with training and exercise characteristics.METHODS: Eighty-eight male endurance cyclists were involved. Demographic data, health condition and training characteristics were collected. Baseline and postexercise blood-samples were collected to determine hsCRP concentrations. A hs-CRP cut-off point of 3 mg/L was used. Blood-cell count and biochemical parameters were measured at baseline. Heart rate (HR) was measured during exercise.RESULTS: Cyclists performed 7.3 hours (interquartilerange (IQR) = 5.4-7.5) of endurance exercise at intensity of 81.8 % (IQR = 74.9-85.8). Cyclists with baseline hsCRP ≥ 3 mg/L reported higher body mass, body mass index (BMI), waist-circumference and total-cholesterol. An increase in hs-CRP was following endurance exercise. Cyclists with any elevation of hs-CRP reported a higher BMI, HR during exercise and exercise intensity. Binary logistic regression analysis showed BMI (OR = 1.24, 95% CI = 1.04-1.48) and cycling distance (OR = 0.22, 95% CI = 0.06-0.76) were associated with post-exercise hs-CRP elevations.CONCLUSION: Body mass, BMI, waist-circumference, total- and HDL-cholesterol are associated with baseline hsCRP, whereas BMI and cycling distance were associated with hs-CRP elevations. These findings suggest that anthropometry parameters and lipid levels attributed to baseline hs-CRP, while anthropometry parameters and cycling intensity attributed to post-exercise hs-CRP elevations.KEYWORDS: C-reactive-protein, exercise, endurancecycling, inflammation, acute-phase-response

Background: The research on association between differentiation of Th1 and Th2 were previously conducted on experimental animals. The study on association between umbilical cord zinc and the risk of allergy symptoms during early stage of life has not been conducted in Indonesia. Studies on zinc and allergies are commonly investigated during adulthood and the results are still contradictive. Objective: The aim of the study is to determine the extent of zinc’s role in the emergence of atopic allergy symptoms during the first 4 months age Methods: This prospective cohort study includes consecutive 80 healthy newborns followed up for 4 months after birth at Semarang Sultan Agung Islamic Hospital and Bangetayu Primary Health Care. Hypothesis testing were analyzed with unpaired t-test , chi-square test or fisher’s test Results: The mean value of cord blood zinc in allergic infants were significantly lower when compared with non atopic allergy (74.1 ± 17.3 μg / dL vs 91.5 ± 22.6 μg / dL, p=0.029). Very early formula feeding were 4.4 times more at risk of suffering from allergies(p=0.023). Conclusion: Umbilical cord zinc levels are associated with atopic allergy symptoms for the first 4 months of life. Formula feeding before 1 month of age was associated with atopic allergic infants Bangladesh Journal of Medical Science Vol.19(1) 2020 p.114-121
