Prevalence of bacterial vaginosis among reproductive age group women in a tertiary care centre

Background: Vaginal discharge in reproductive age poses a serious problem in the developing countries. Bacterial vaginosis also known as non-specific vaginitis is the most common cause of vaginal infections, detecting the organism at an early stage and initiating a proper treatment is very difficult in our country due to lack of awareness and proper follow-up. The disease manifests in the form of vaginal discharge with or without itching. It has a strong association with preterm labor, preterm premature rupture of membranes and low birth weight in pregnancy. The objective of this study was to find out the prevalence of bacterial vaginosis among the reproductive age group women, in a tertiary care centre.Methods: A cross sectional study was conducted among 150 women of the reproductive age group in the department of obstetrics and gynaecology Sree Mookambika Institute of Medical Sciences over a period of one month October 2018 the diagnosis was made with history and nugents scoring system.Results: Out of the total 150 women enrolled in the study 74 had positive results, 50% of them were of the age group 26-30.Conclusions: The study shows us the high prevalence of bacterial vaginosis.

Nucleotide sequences of a cDNA coding for rat hck tyrosine kinase and characterization of its gene product.

The hck gene is member of src family of non-receptor type tyrosine kinases. Here we report the nucleotide sequence of the rat hck eDNA of 1.94 kb. The nuclcotide sequence shows an open reading frame coding for a polypeptide of 503 amino acids. A vector expressing a fusion protein of glutathione-S-transferase with 82 amino acids of the N-terminal region of hck (from amino acids 32 to 113) was constructed, Using this bacterially expressed fusion protein antibodies were prepared which recognize the cellular hck gene product. These antibodies identified, by immunoblotting, two polypeptides of 56 and 59 kDa in rat spleen where hck transcripts are present at high level. Immunoprecipitated hck polypeptides were enzymatically active and were autophosphorylated in the presence of ATP and Mg2+. 1mmunoprecipitated hck could phosphorylate exogenous substrates. Treatment of immunoprecipitated hck by a purified protein tyrosine phosphatase decreased its enzymatic acitivity. Our results suggest that the enzymatic activity of hck tyrosine kinase is regulated by phosphorylation and dephosphorylation.

Molecular cloning of a membrane bound tyrosine-specific protein kinase from rat spleen.

Tyrosine-specific protein phosphorylation is believed to play an important (though poorly understood) role in various cellular functions in many normal and malignant cells. In order to understand the function of tyrosine-specific protein kinases in normal cells, it is necessary, as an initial step, to identify genes (and proteins) for these enzymes. For this purpose cDNA libraries were constructed in plasmid vector pGEM-3Z and lambda gt11 using mRNA from rat spleen. From these cDNA libraries, cDNA clones coding for a src-related tyrosine-specific protein kinase were isolated. The largest clone (L115) was 1.94 kb in size. Various restriction fragments of this clone were subcloned in plasmid vector for sequencing. The complete nucleotide sequence of the largest clone showed an open reading frame coding for a protein of 503 amino acids. The presence of a glycine at position 2 and an arginine at position 7 indicated that this protein is likely to be acylated at glycine 2 and therefore associated with plasma membrane. This gene showed high homology to human and mouse hck and hence it is perhaps the rat homologue of hck. Moderate level of expression of this gene was observed only in the adult rat spleen and not in other tissues. These results suggest that this kinase gene is expressed in a tissue specific manner.
