Abstract:Background: Chemotherapy is a common treatment for leukemia as well as in other cancer treatment. The lack of tumor selectivity and development of multi-drug resistance by chemotherapy caused the development of new strategy in cancer treatment become a pressing need. This study was performed to evaluate the anticancer activity and selectivity of seven derivatives of chalcones against K562 and HL-60 leukemia cell lines. Materials and Methods: The cytotoxicity of chalcone’s seven derivatives (compound 1-7) was tested by using MTS (3-(4,5-dimethylthiazol-2-yl)-5-(3-carboxyme-thoxyphenyl)-2-(4-sulfophenyl)-2H-tetrazolium) method. The percentage of cell mortality data was calculated then the IC50 was analyzed using probit analysis (SPSS 17). The selectivity index (SI) then calculated from IC50 ratio of normal lymphocyte cells and cancerous cells line (HL-60 and K562).Results: The IC50 of almost all seven tested compounds were lower in HL-60 cell lines than K562 cell lines, except for Compound 7. The number and position of methoxy groups in chalcone derivatives influenced the anticancer and cancer selectivity of chalcone derivatives.Conclusion: The results revealed that the number and position of methoxy groups in chalcone derivatives influenced the anticancer and cancer selectivity of chalcone derivatives.Keywords: anticancer, chalcone derivatives, methoxy-4’-amino chalcone, leukemia, cytotoxic, selectivity

Abstract:Background: It is important to maintain the adequate level of vitamin B6 to ensure stable metabolism. Vitamin B6 serum level might decreased by absorption disturbance or increasing demand. Valproic acid increase the synthesis of serum GABAergic in the other hand vitamin B6 is required as cofactor for gamma-amino butyric acid (GABA) formation. The dosage and duration of valproic acid therapy might be correlated with vitamin B6 serum level. The aim of this study is to know the correlation between vitamin B6 serum level against dosage and duration of valproic acid therapy in children with epilepsy.Materials and Methods: This is a cross sectional study to investigate the correlation between vitamin B6 serum level against dosage and duration of valproic acid therapy. The level of vitamin B6 serum was determined by checking vitamin B6 active form in serum, pyridoxal 5’-phospate (PLP).Results: In this study, 37 epilepsy children with valproic acid duration therapy more than 3 months was enrolled. Fifty six percent epilepsy children were male, commonly on children age 1-5 years old. Spearman correlation coefficient test showed a significant weak negative correlation between vitamin B6 serum level and dosage of valproic acid (r=–0.35; p=0.03), and very weak negative correlation with valproic acid duration therapy (r=-0.08; p=0.59), however it was not significant. Conclusion: There was a significant weak negative correlation between vitamin B6 serum level and very weak negative correlation with valproic acid duration therapy, but not significant in children with epilepsy.Keywords: correlation, valproic acid, vitamin B6

Abstract:Background: Children’s immunity system is relatively lower on first year of life, causing atopic babies, leading to allergy. Ideally, newborn babies are given breast milk as main food source on the first 6 months, but often being replaced with cow milk which can induce Cow’s Milk Protein Allergy. For the alternative can replace it with soymilk formula which contains phytoestrogen from isoflavon, which works just like estrogen. The aim of this study to determine whether administration of soymilk formula is capable on increasing estrogen level and reducing testosterone level on male infant white Wistar rats (Rattus norvegicus).Materials and Methods: This research used post test only control group design. Samples were consisted of 36 infant male white Wistar rats aged 7 days, weighing from 10-15 grams, divided into 2 groups, control group which was given cow’s milk and intervention group which was given soymilk. Each group were given intervention with the dose 5% of BW (grams), given twice-a-day orally for 21 days, and subsequently in the morning their blood samples were taken to examine the level of estrogen and testosterone hormone.Results: The study showed that the level of estrogen on intervention group was significantly higher than the control group with mean estrogen level of 0.55±0.03 pg/mL in the control group and 0.82±0.01 pg/mL in the intervention group, while the mean testosterone level was significantly lower on intervention group compared with control group (p

Abstract:Background: Many studies had discovered that early onset severe preeclampsia (EO-PE) has worst maternal and neonatal outcome compared to late-onset type (LO-PE), related to its placental involvement. Severe preeclampsia was defined as newly onset severe hypertension developed after 20 weeks gestation in previously normal blood pressure women, with coexistence of proteinuria, or maternal organ or uteroplacental dysfunction. Hemeoxygenase-1 (HO-1) is an enzyme with multiple effect which is protective to pregnancy.Materials and Methods: The total study subjects were 40 pregnant women consisted of 10 EO-PE, 10 normal early onset pregnancy (EO-NP), 10 LO-PE, and 10 normal late onset pregnancy (LO-NP). As much as 5 cc of plasma from umbilical cord was taken as soon as the baby was born, and the HO-1 level was examined by enzyme-linked immunosorbent assay (ELISA). The primary outcome were umbilical cord HO-1 level and neonatal composite morbidity (low Apgar score, low birthweight, length of stay >5 day, respiratory distress syndrome, jaundice and neonatal death).Results: The plasma level of HO-1 in EO-PE subjects were lower than EO-NP (0.96±0.37 ng/mL vs. 2.43±0.58 ng/mL, p

Abstract:Background: Microtia is a congenital malformation in the external ear due to cartilage defect. Adipose-derived stem cells (ADSC) is promising cells to develop cartilage tissue engineering for microtia. In this study, we focused on proliferation and chondrogenesis of ADSC in three different media, which consist of 10% fetal bovine serum (FBS), 10% FBS with L-ascorbic acid, and 10% human platelet rich plasma (PRP). Methods: ADSC were induced to differentiate into adipocytes, chondrocyte and osteocytes. ADSC morphology, proliferation and population doubling time was compared in three different media and analysed. Observation and alcian blue staining were done every 7 days to assess chondrogenic potency of ADSC from each treatment.Results: Isolated ADSC were able to differentiate into adipocytes, osteocytes and chondrocytes. ADSC in all group have fibroblast-like morphology, but cells in 10% FBS and 10% FBS with LAA group were flattened and larger. ADSC in 10% PRP group proliferates faster than 10% FBS with and without LAA. PDT values of ADSC were 34 hours, 44 hours and 48 hours, respectively for 10% PRP, 10% FBS with LAA and 10% FBS group. Alcian blue staining revealed that ADSC in 10% FBS with LAA and 10% PRP were able to proceed to chondrogenesis when cultured time were prolong up to 21 days, but not with ADSC in 10% FBS. Conclusion: We conclude that adding 10% FBS with LAA or 10% PRP into medium culture can support proliferation and chondrogenesis of ADSC. Key words: human ADSC, PRP, L-ascorbic acid, proliferation, chondrogenesis

Abstract:Background: Malaria is still a universal health problem, especially in tropical countries because of high morbidity and mortality rates. Infection by Plasmodium falciparum and Plasmodium vivax could result in asymptomatic disease of malaria and be found in Trenggalek, Jawa Timur. Differences in pathogenesis among affected individuals are affected by many factors, and the immune system is one of them. Among substances involved in the malarial immunity is Tumor Necrosis Factor (TNF)-α and Interleukin (IL)-10, produced by the body's defense system as the reaction to the parasite. Therefore a study was designed to detect the level of TNF-α and IL-10 in asymptomatic malaria patients.Materials and Methods: A cross-sectional study was conducted. Thirty male asymptomatic malaria subjects, age 21 to 60 years were selected. Blood from each subject was collected and the levels of TNF-α and IL-10 were analyzed using enzyme-linked immunosorbent assay (ELISA) method. Significant values considered at p0.05), and positive correlation between TNF-α and the rate of hemoglobin (r=0.002; p>0.05). IL-10 was correlated negatively with the rate of hemoglobin (r=-0.363; p

Abstract:Background: A pressure ulcer (PU) is localized injury to the skin and/or underlying tissue usually over a bony prominence, as a result of pressure, or pressure in combination with sharp surface. Several studies have found that PU is also a common problem in the pediatric population. Infection at PU sites is the most common complication, where PU can host resistant microorganisms and can turn into a local infection that is a source of bacteremia in hospital patients. This study aims to determine the most common bacteria and antimicrobial susceptibility at the site of PU in pediatric patients that serve as baseline data in Haji Adam Malik Hospital.Materials and Methods: A cross-sectional study was carried out in July-December 2017, involving 30 PU pediatric patients. For each subject, swab from ulcers were cultured in microbial laboratory to determine the microbial pattern and antimicrobial susceptibility.Results: The most common age group was 0-3 (53.3%), the highest gender was male (60%), the most common type was type 2 (46.7%), the main location was occipital (30%) and the most common undelying diseases were hydrocephalus (16.6%). The most common microbial pattern in PU pediatric patients is Acinetobacter baumannii (40%). The highest sensitivity is vancomycine for gram positive bacteria and amikacine for gram negative bacteria.Conclusion: The most common microbial pattern in PU pediatric patients in Haji Adam Malik Hospital is Acinetobacter baumannii (40%). The highest sensitivity is vancomycine for gram positive bacteria and amikacine for gram negative bacteria.Keywords: pressure ulcer, pediatric, microbial pattern, antimicrobial susceptibility

Abstract:Background: Recently we have isolated and cultured dental pulp stem cell (DPSC) derived from impacted third molar (DPSC-M3). The DPSC-M3 was suggested as mesenchymal stem cell, however the cell surface markers were not completely clarified. Therefore current study was conducted to investigate the markers.Materials and Methods: Passage 5 DPSC-M3 was cultured, labeled and examined with flow cytometer. All markers were investigated according to the proposed cell surface marker panel for the minimal identification of human mesenchymal stem cell (MSC) by International Society for Cellular Therapy (ISCT). The positive markers were cluster of differentiation (CD)90, CD73, CD105, while the negative markers were CD34, CD45, CD11b, CD19, and Human Leukocyte Antigen (HLA)-DR. Results: Results showed that the size and granularity of DPSC-M3 were ranged from 75 to 230 and 27 to 203, respectively. The cell surface antigens examination showed that CD90, CD105 and CD73 were highly expressed (>95%), meanwhile expressions of CD45, CD34, CD11b, CD19 and HLA-DR were
