Summary The effect of prostaglandin E2 on the activity of the pregnant human uterus in vivo has been studied in 50 women at or near term and in need of induction. Labour was successfully induced in all cases with a continuous infusion of 0·5 μg./min. The uterine activity produced by prostaglandin infusion resembled that of normal spontaneous labour. No unphysiological increase in uterine tonus was observed. The average infusion time was 5·5 hours and the average infusion‐delivery interval was 10 hours.
BackgroundNeuropeptide Y (NPY) is known to play a role in the regulation of satiety, energy balance, body weight, and insulin release. Interleukin-1beta (IL1B) has been associated with loss of beta-cell mass in type-II diabetes (TIID).ObjectivesThe present study attempts to investigate the association of NPY exon2 +1128 T/C (Leu7Pro; rs16139), NPY promoter -399 T/C (rs16147) and IL1B -511 C/T (rs16944) polymorphisms with TIID and their correlation with plasma lipid levels, BMI, and IL1B transcript levels.MethodsPCR-RFLP was used for genotyping these polymorphisms in a case-control study involving 558 TIID patients and 1085 healthy age-matched controls from Gujarat. Linkage disequilibrium and haplotype analysis of the NPY polymorphic sites were performed to assess their association with TIID. IL1B transcript levels in PBMCs were also assessed in 108 controls and 101 patients using real-time PCR.ResultsOur results show significant association of both structural and promoter polymorphisms of NPY (p<0.0001 and p<0.0001 respectively) in patients with TIID. However, the IL1B C/T polymorphism did not show any association (p = 0.3797) with TIID patients. Haplotype analysis revealed more frequent association of CC and CT haplotypes (p = 3.34 x 10−5, p = 6.04 x 10−9) in diabetics compared to controls and increased the risk of diabetes by 3.02 and 2.088 respectively. Transcript levels of IL1B were significantly higher (p<0.0001) in patients as compared to controls. Genotype-phenotype correlation of IL1B polymorphism did not show any association with its higher transcript levels. In addition, NPY +1128 T/C polymorphism was found to be associated with increased plasma LDL levels (p = 0.01).ConclusionThe present study provides an evidence for a strong correlation between structural and promoter polymorphisms of NPY gene and upregulation of IL1B transcript levels with susceptibility to TIID and altering the lipid metabolism in Gujarat population.
High doses of cytosine arabinoside (ara-C) have been used in the treatment of refractory forms of acute nonlymphoblastic leukemia (ANLL) and ANLL occurring after previous antineoplastic therapy. In addition to the usual toxicities associated with antimetabolites, neurotoxicity, mainly in the form of cerebellar dysfunction, develops in a significant proportion of patients receiving high-dose cytosine arabinoside HDara-C. This study was performed to determine the incidence of cerebellar dysfunction in our patients and to determine any factors that predict its development. In this series of 30 consecutive patients receiving HDara-C, confusion with cerebellar signs and symptoms developed in seven (23%). Factors that appear to predispose patients to the development of neurotoxicity are (1) past history of neurologic dysfunction and (2) preexisting and progressive hepatic dysfunction. No peripheral neuropathy was seen. In contrast to previous reports, we did not find neurotoxicity to be dose related. Prophylactic use of pyridoxine does not prevent neurotoxicity.
Resistin, an adipokine, is involved in obesity and Type 2 Diabetes (T2D). The current study evaluates the association between RETN polymorphisms (-638 G/A, -420C/G & -358 G/A) and the risk towards T2D. Controls and T2D patients were enrolled from Gujarat, India. Polymorphisms of RETN were genotyped by Polymerase Chain Reaction-Restriction Fragment Length Polymorphism. For the genotype-phenotype correlation analysis Fasting Blood Glucose (FBG), Body Mass Index (BMI) and plasma lipid profile were used. Plasma levels of resistin were assayed by ELISA. Our study suggests an association of RETN -420C/G polymorphism with T2D risk. The CC genotype of RETN -420C/G polymorphism was found to be associated with FBG, BMI, and total cholesterol. Plasma resistin levels were found to be significantly increased in diabetic patients as compared to controls. Our findings suggest -420C/G polymorphism of RETN as an important factor which could pose a powerful risk towards T2D susceptibility.
Adiponectin is a prime determinant of the status of insulin resistance. Association studies between adiponectin (ADIPOQ) gene single nucleotide polymorphisms (Snps) and metabolic diseases have been reported earlier. However, results are ambiguous due to apparent contradictions. Hence, we investigated (1) the association between ADIPOQ Snps: −11377C/G, +10211T/G, +45T/G and +276G/T for the risk towards type 2 diabetes (T2D) and, (2) genotype-phenotype association of these SNPs with various biochemical parameters in two cohorts. Genomic DNA of diabetic patients and controls from Gujarat and, Jammu and Kashmir (J&K) were genotyped using PCR-RFLP, TaqMan assay and MassArray. transcript levels of ADIPOQ were assessed in visceral adipose tissue samples, and plasma adiponectin levels were estimated by qPCR and ELISA respectively. Results suggest: (i) reduced HMW adiponectin/ total adiponectin ratio in Gujarat patients and its association with +10211T/G and +276G/T, and reduced ADIPOQ transcript levels in T2D, (ii) association of the above SNPs with increased FBG, BMI, TG, TC in Gujarat patients and (iii) increased GGTG haplotype in obese patients of Gujarat population and, (iv) association of −11377C/G with T2D in J&K population. Reduced HMW adiponectin, in the backdrop of obesity and ADIPOQ genetic variants might alter metabolic profile posing risk towards T2D.Metabolic Syndrome (MS) is the new wave of diseases that has hit the human population in the last few decadesthe Metabolic Syndrome Era. It has become pandemic and with obesity and type 2 diabetes (T2D) clubbed under the MS umbrella, millions of people around the globe have come under its grip. Though obesity and T2D are ubiquitous, there exists a pattern of prevalence based on ethnicity. A recent report has identified demographic transitions, nutrition and lifestyle in the backdrop of genetic predisposition as the chief factors responsible for the rising trend of obesity associated amongst South Asians 1 . Over accumulation of visceral adipose tissue (AT) has been identified as one of the major driving factors towards T2D. Adipose tissue is an important regulator of metabolic homeostasis by virtue of the adipokines (pro-inflammatory and anti-inflammatory) that it secretes. In obese conditions, the fine-tuned balance between the pro-and anti-inflammatory adipokines gets altered leading to various metabolic disorders 2 . These bioactive peptides act locally and distally to calibrate and fine tune various metabolic pathways. Adiponectin is one such calibrator which is abundantly expressed in white adipose tissue 3 . It circulates in three polymorphic forms, low molecular weight (LMW), moderate molecular weight (MMW) and high molecular weight (HMW). Interestingly, the ratio of plasma HMW adiponectin to total adiponectin is more strongly correlated with plasma glucose levels than any of the forms alone 4 . Adiponectin gene (ADIPOQ/ APM1/GBP28) locus, 3q27, has been strongly associated with a variety of metabolic disorders like-impaired glucose tolerance, obesity, dys...
