Purpose. We aim to identify the methylation status of delta-like 1 (DLK1) in the placenta and the correlation between DLK1 methylation and maternal serum glucose level and fetal birth weight. Methods. We analyzed the gene expression of DLK1 gene in both maternal and fetal sides of the placenta in a GDM group (n=15) and a control group (n=15) using real-time polymerase chain reaction. With MethylTargetTM technique, we detected the methylation status of DLK1 promotor in the placenta. Furthermore, Pearson’s correlation was used to confirm the association of methylation alteration of DLK1 promoter and maternal 2 h OGTT glucose level and fetal birth weight. Results. In our study, we found that DLK1 expression in both maternal and fetal sides of the placenta decreased significantly in GDM group compared with control group, and it was caused by hypermethylation of DLK1 promoter region. Additionally, the methylation status of DLK1 gene in the maternal side of the placenta highly correlated with maternal 2 h OGTT glucose level (coefficient=0.7968, P<0.0001), while the methylation status in the fetal side of the placenta was closely related to fetal birth weight (coefficient=0.6233, P<0.0001). Conclusions. Our results demonstrated that altered expression of DLK1 was caused by the hypermethylation of DLK1 promoter region in the placenta, and intrauterine exposure to GDM has long-lasting effects on the epigenome of the offspring.

Visfatin Level

Background: Adipocytokines have been recently implicated in the pathogenesis of preeclampsia. Visfatin is one of such adipokines. Objective: To determine the association between serum visfatin levels and preeclampsia. Methods: A prospective, case-control study was carried out in 160 pregnant women consisting of 80 pre-eclamptics and 80 normotensive controls, matched for age and parity during the third trimester. Maternal serum visfatin levels were determined in both groups using a visfatin (Human) enzyme- linked immunosorbent assay. Serum Visfatin levels were compared between the groups and correlated to the blood pressure, proteinuria, fetal birth weight and Apgar scores. Results: The mean serum visfatin level was significantly higher (10.3±6.9 ng/ml) in preeclampsia than (7.4±4.4 ng/ml) in the control group (p=0.001). The mean serum visfatin level was higher in severe pre-eclamptics (10.8±8.9 ng/ml) compared to (9.6±5.8ng/ml) in mild preeclamptics and this was statistically significant (p=0.021). Visfatin levels showed a negative and non-significant correlation with both systolic (r= -0.011 and p=0.924), diastolic blood pressure (r= -0.012, p=0.913) and body mass index (r= -0.142, p=0.209) in both study and control groups. Mean birth weight was significantly lower in the preeclampsia (2.8±0.25 kg) compared to the control group (3.2±0.31 kg) P=0.000. the mean birth weight was lower in severe preeclampsia (2.7±0.25 kg compared to 2.9±0.39 in mild preeclamsia. There was no significant correlation between the visfatin levels and Apgar score at 5minutes and birth weights in both groups (P=>0.05). Conclusion: This study showed a significant increase in the level of visfatin in preeclampsia compared to their normo-tensive controls. However, this increased level was not consistent with the severity of the disease.

Abstract Background DNA methylation is an epigenetic process for modifying transcription factors in various genes. Methylenetetrahydrofolate reductase (MTHFR) stimulates synthesis of methyl radical in the homocysteine cycle and delivers methyl groups needed in DNA methylation. Furthermore, numerous studies have linked gene polymorphisms of this enzyme with a larger risk of recurrent pregnancy loss (RPL), yet scarce information is available concerning the association between epigenetic deviations in this gene and RPL. Hypermethylation at precise DNA sequences can function as biomarkers for a diversity of diseases. We aimed by this study to evaluate the methylation status of the promoter region of MTHFR gene in women with RPL compared to healthy fertile women. It is a case–control study. Hundred RPL patients and hundred healthy fertile women with no history of RPL as controls were recruited. MTHFR C677T was assessed by polymerase chain reaction-restriction fragment length polymorphism (RFLP). Quantitative evaluation of DNA methylation was performed by high-resolution melt analysis by real-time PCR. Results The median of percentage of MTHFR promoter methylation in RPL cases was 6.45 [0.74–100] vs. controls was 4.50 [0.60–91.7], P value < 0.001. In the case group, 57 hypermethylated and 43 normo-methylated among RPL patients vs. 40 hypermethylated and 60 normo-methylated among controls, P< 0.005. Frequency of T allele in C677T MTHFR gene among RPL patients was 29% vs. 23% among the control group; C allele vs. T allele: odds ratio (OR) = 1.367 (95% confidence interval (CI) 0.725–2.581). Conclusion Findings suggested a significant association between hypermethylation of the MTHFR promoter region in RPL patients compared to healthy fertile women.

Background : Pregnancy is a state of physiological adaptations to accommodate the needs of the developing fetus. Elevated blood glucose during pregnancy could lead to gestational diabetes and anemia could cause intercurrent infection.Objective: To assess the serum glucose level & hemoglobin concentration in third trimester of pregnancy in order to find out the risk of gestational diabetes and physiological anemia.Method: This cross-sectional study was carried out in the Department of Physiology Mymensingh Medical College, Mymensingh, between the period of July, 2013 to June,2014. One hundred pregnant women in their third trimester of pregnancy aged 18-35years were enrolled in study group and age matched 100 healthy non-pregnant women were control group. Random serum glucose was estimated by GOD-PAP method and hemoglobin concentration was measured by cyanmethemoglobin (CMG) method. Data were analyzed by student’s un paired t test and chi square test.Result: Mean serum glucose level (6.76±1.72 mmol/L) was significantly higher and hemoglobin concentration (8.21±1.23 g/dl) was significantly lower in pregnant women than non-pregnant women. Increased frequency of high glucose (38%) and low H b(88%) was found in pregnant women in third trimester.Conclusion: This study concludes altered glucose metabolism may lead to gestational diabetes as well as physiological anemia may be exaggerated in third trimester of pregnancyBangladesh Soc Physiol. 2015, December; 10(2): 67-70

Duration Of Pregnancy

This study was aimed at evaluating the association between gestational diabetes mellitus (GDM) and fetal birth weight considering duration of pregnancy, maternal age and body mass index (BMI). This was a retrospective cross-sectional study followed by cohort type of study. Initially, pregnant women in their 24 to 28th week of gestation were selected for determining their fasting blood glucose (FBG) level and blood glucose level 2 hrs after 75 g oral glucose intake. The cut-off value for the diagnosis of GDM was > 5.3 mmol/l for FBG level and > 8.6 mmol/l for taking 75 g oral glucose intake after 2 hrs. Both GDM and control group subjects were followed up to neonatal period to find out neonatal outcomes. Among the total 215 subjects, 84 pregnant women were selected with GDM and rest 131 were control. It is found that GDM alone had a significant (p = 0.05) positive effect on both the duration of pregnancy and fetal birth weight, but not on maternal BMI. Both the effects of duration of pregnancy and GDM are considered together on fetal birth weight, only GDM had significant impact on fetal birth weight compared to the control group. Similarly, when the effect of maternal BMI and GDM is considered together on fetal birth weight, only GDM group was found to have significant effect on fetal birth weight. Parallel results were observed for the effect of both maternal age and GDM on fetal birth weight. In binary logistic regression analysis, when the differences are considered in maternal age, duration of pregnancy and maternal BMI along with GDM, both maternal age ≥ 35 years (OR: 9.43, p = 0.001) and GDM (OR: 10.60, p = 0.003) was found to have significant positive effect on fetal birth weight. It was found that the GDM showed significant influence on fetal birth weight considering the effects of maternal age, duration of pregnancy and maternal BMI. Dhaka Univ. J. Biol.

AbstractManilkara hexandra (Roxb.) Dubard (common name Khirni, family: Sapotaceae) is an evergreen traditionally used medicinal plant. The present study aimed to see the effects of leaf aqueous extract of M. hexandra (LAEMH) on digestive and glucose metabolic enzyme action and serum glucose level in rohu, Labeo rohita, fingerlings. Experimental fish were fed a basal diet (Group I), and diets supplemented with LAEMH at 300 mg (Group II) and 600 mg (Group III) kg−1 body weight. A significant reduction in serum glucose was noticed in the treated groups when compared with the control group. The reduced amylase activity was noticed in the treated fingerlings in a dose-dependent manner. However, lipase and protease activities didn’t differ significantly among the experimental groups. Reduced serum glucose level might be correlated with the decline in the activity of digestive amylase in fish. Group II (3.35±0.19U) and Group III (3.49±0.13 U) were recorded with reduced glucose-6-phosphatase activities than the control group (4.4±0.39 U). Moreover, the study revealed a decline in fructose-1,6-phosphatase activities in the treated groups in comparison to the control group. The decline in the activities of the metabolic enzymes might be associated with the non-availability of glucose owing to reduced activity of the digestive amylase in the treated groups. In conclusion, the present study established the hypoglycaemic effect of the leaf aqueous extract of M. hexandra in a fish model.

Metformin is now being recognized as the standard therapy in T2D patients who are overweight. Metformin has many drug-disease interactions that can increase the risk of metformin-associated lactic acidosis. Therefore this study was conducted to evaluate any possible pharmacodynamic interactions between metformin and drugs used to treat chronic diseases e.g. Hypertension. The rats were fasted overnight before inducing diabetes with streptozotocin. The rats were given an intraperitoneal injection of streptozotocin (50 mg kg−1) freshly prepared in 0.1M sodium citrate buffer. The diabetic state was confirmed 72 h after streptozotocin injection. Diabetic rats were grouped into seven groups each group of five rats and distributed among the normal control group diabetic control group and the treatment groups. The treatment continued for 10 days. Blood samples were taken before treatment and after 10 days and analyzed for serum glucose, cholesterol, HDL, LDL, and triglycerides. In the diabetic control group which was given STZ alone the blood glucose level decreased significantly (p &lt; 0.05) after 10 days but still above the hyperglycemic level (200mg/dl). The same was observed in the group treated with metformin. The group treated with nifedipine and aspirin showed significant reduction (p &lt; 0.01) in the glucose level below the hyperglycemic level (200mg/dl). While the groups treated with (Metformin + Nifedipine) and (Metformin +Aspirin) showed highly significant reduction (P&lt;0.001) in blood glucose level. These results conclude that the combination of (metformin +Nifedipine) and the combination of (Metformin + Aspirin) have highly significant hypoglycemic effect. It also showed that Nifedipine has promising role in reducing blood glucose level, lipid profile especially LDL-cholesterol, and body weight.

The study was conducted to investigate the effects of caffeine treatment during organogenesis period to the fetal birth weight, using rat (Rattus norvegicus) as the animal model. Thirty-six primipararat obtained from Unit Pengembangan Hewan Percobaan, Gadjah Mada University (UPHP-GMU), 3 month old, 165-200 g body weight, were divided into 6 groups, consisted of 6 rats each. Six of the ratshave been selected based on the estrous cycles, and only rat with regular estrous were use for theexperiment. The rat then were mated, and during day 6-14 of the pregnancies were treated orally withcaffeine diluted in aquadest in dosage: placebo (1 cc aquadest) for group I (control), and 5.4, 10.8, 16.2,21.6, and 27 g/200 g body weight/day for treatment groups II-VI respectively. The pregnant rat bodyweights were determined at day 6 of pregnancies for calculating the caffeine treatment dosages. At day 20thof the pregnancies all of the pregnant rats were caesarotomized, and all of the fetuses were removed and weighed. The results showed that all of the treatment groups have significantly lower birth weightcompare to the groups control group. More over, fetal obtained from the treatment groups also showedserious subcutaneous hemorrhagic.Keywords: organogenesis, Rattus norvegicus, birth weight
