ABSTRACT
Background: Today, female feticide and gender preference are a big problem in India. Although there is so much emphasis against it, the problem has become aggravated. In this context, various studies showed that the male child preference leads to skewed sex ratio. The present paper is an attempt to determine the view of the people for giving their preference to the male child. Objectives: The objectives were to study the preference of women for gender of child, as well as reasons for preference for it, and association between socioeconomic factors and demographic factors with gender preference. Materials and Methods: It is a community-based cross–sectional study, in which 500 married women of 15–49 years of reproductive age group, 150 randomly selected women from one urban municipal ward, and 350 randomly selected women from seven villages of rural area were constituted the study population. Widow and separated women were excluded from the study. A pre-tested, semi‑structured questionnaire was administered to each individual to collect information. Microsoft Excel 2007 software and the Chi‑square test were used. Results: Almost half of the women (51.4%) have preference for male child. Women from lower age group (65.25%), currently married (66.42%), Muslim religion (72.22%), lower education (59.01%), and low socioeconomic status (66.67%) and those who are laborer (71.83%) have male child preference. Conclusions: This study concludes that more number of females have preference for male child in women of younger age group. Muslim religion and its customs, thoughts, and rearing practices make difference. Lower socio-economic status and poor education are also major contributory factor. Male child will support in old age and will take social responsibilities are the main basic reasons found to be associated with male child preference.
ABSTRACT
A highly sensitive and selective high performance liquid chromatography–tandem mass spectrometry method was developed and validated for the quantification of alverine (ALV) and its active metabolite, para hydroxy alverine (PHA), in human plasma. For sample preparation, solid phase extraction of analytes was performed on Phenomenex Strata-X cartridges using alverine-d5 as the internal standard. The analytes were separated on Symmetry Shield RP18 (150 mm×3.9 mm, 5 μm) column with a mobile phase consisting of acetonitrile and 10 mM ammonium formate (65:35, v/v). Detection and quantitation was done by electrospray ionization mass spectrometry in the positive mode using multiple reaction monitoring. The assay method was fully validated over the concentration range of 15.0–15,000 pg/mL for ALV and 30.0–15,000 pg/mL for PHA. The intra-day and inter-day accuracy and precision (%CV) ranged from 94.00%to 96.00%and 0.48%to 4.15%for both the analytes. The mean recovery obtained for ALV and PHA was 80.59% and 81.26%, respectively. Matrix effect, expressed as IS-normalized matrix factor ranged from 0.982 to 1.009 for both the analytes. The application of the method was demonstrated for the specific analysis of ALV and PHA for a bioequivalence study in 52 healthy subjects using 120 mg ALV capsules. The assay reproducibility was also verified by reanalysis of 175 incurred subject samples.
ABSTRACT
The present study describes a simple, reliable and reproducible liquid chromatography–tandem mass spectro-metry method (LC–MS/MS) for the simultaneous determination of allopurinol and its active metabolite, oxypurinol in human plasma for a pharmacokinetic/bioequivalence study. After protein precipitation (PPT) of 100 μL plasma sample with 1.0%formic acid in acetonitrile, the recovery of the analytes and allopurinol-d2 as an internal standard ranged from 85.36% to 91.20%. The analytes were separated on Hypersil Gold (150 mm×4.6 mm, 5 μm) column using 0.1% formic acid-acetonitrile (98:2, v/v) as the mobile phase. Quantification was done using electrospray ionization in the positive mode. The calibration concentration range was established from 60.0 to 6000 ng/mL for allopurinol and 80.0–8000 ng/mL for oxypurinol. Matrix effect in human plasma, expressed as IS-normalized matrix factors ranged from 1.003 to 1.030 for both the analytes. The developed method was found suitable for a clinical study with 300 mg allopurinol tablet formulation in healthy subjects.
ABSTRACT
An improved high performance liquid chromatography–tandem mass spectrometry (LC–MS/MS) method has been developed for sensitive and rapid determination of albendazole (ABZ) and its active metabolite, albendazole sulfoxide (ABZSO), in the positive ionization mode. The method utilized solid phase ex-traction (SPE) for sample preparation of the analytes and their deuterated internal standards (ISs) from 100 mL human plasma. The chromatography was carried out on Hypurity C18 column using acetonitrile-2.0 mM ammonium acetate, pH 5.0 (80:20, v/v) as the mobile phase. The assay exhibited a linear re-sponse over the concentration range of 0.200–50.0 ng/mL for ABZ and 3.00–600 ng/mL for ABZSO. The recoveries of the analytes and ISs ranged from 86.03%–89.66% and 89.85%–98.94%, respectively. Matrix effect, expressed as IS-normalized matrix factors, ranged from 0.985 to 1.042 for the both analytes. The method was successfully applied for two separate studies in healthy subjects using single dose of 400 mg conventional tablets and 400 mg chewable ABZ tablets, respectively.
