RESUMEN
Background: Polycystic ovary syndrome (PCOS), associated with a state of low grade chronic inflammation, depends on multiple genetic and environmental factors. Elevated levels of inflammatory markers including intercellular adhesion molecule-1 (ICAM-1) have been demonstrated in affected women. Recent evidence indicates a significant linkage between chromosome 19p13 loci and multifactorial diseases that have an inflammatory component. The aim of this study was to assess the possible association of the lys469glu (K469E) polymorphism of the ICAM-1 gene located on chromosome 19p13 with risk of PCOS in Kashmiri women. Material and Methods: The K469E single nucleotide polymorphism (SNP) was analysed with DNA from peripheral blood leukocytes of 220 PCOS cases and 220 age matched non-PCOS healthy controls using PCR-RFLP. Results: Genotypic frequencies in cases were found to be 32 (14.5%) for EE, 98 (44.5%) for KE, and 90 (40.9%) for KK, with 130 (59.1%) for the KE+EE genotypes compared to healthy control values of 29 (13.2%) for EE, 113 (51.4%) for KE, 78 (35. 5%) for KK and 142 (64.5%) for KE+EE combined.The odds ratios for the EE, KE and KE:EE genotypes were 0.95(95% CI= 0.53-1.71)[p= 0.88], 0.75(95% CI= 0.50-1.12)[p =0.168] and 0.79 (95% CI =0.53-1.16) [p = 0.23], no statistically significant differences being found between cases and controls (χ2 =2.07; p=0.35). Conclusion: In conclusion, there was no apparent significant influence of the K469E polymorphism on risk of PCOS, or any clinical or laboratory parameters.
RESUMEN
In-vitro antimicrobial and antioxidant activities of various concentrations ranging from 150 to 500 µg/ml of alcoholic (methanol and ethanol) extracts of Rumex dentatus were analyzed on different clinical bacterial strains (Shigella flexneri, Klebsiella pneumoniae, Escherichia coli, Pseudomonas aeruginosa, Salmonella typhimurium, Staphylococcus aureus) and fungal strains (Aspergillus versicolor, Aspergillus flavus, Acremonium spp., Penicillium dimorphosporum, Candida albicans, Candida kruesie, Candida parapsilosis) using agar disk diffusion method and broth dilution method (MIC and MBC determination) for antimicrobial activity and DPPH (1,1-diphenyl-2-picrylhydrazyl) assay, Riboflavin photo-oxidation assay, deoxyribose assay, lipid peroxidation assay for antioxidant activity. The extracts showed maximum inhibitory effect against K. pneumonia and P. aeruginosa with no activity against S. typhimurium from among the bacterial strains while as in case of the fungal strains the maximum effect was observed against C. albicans by both the extracts. MIC and MBC values determined for active fractions of the extracts against some bacterial strains (S. flexneri, K. pneumonia and E. coli) revealed that the test organisms were inhibited by all the extracts with methanol showing lower values of both MIC and MBC indicating it as a better antimicrobial agent. The antioxidant activity showed that the extracts exhibited scavenging effect in concentration-dependent manner on superoxide anion radicals and hydroxyl radicals leading to the conclusion that the plant has got a broad spectrum antimicrobial and antioxidant activity and could be a potential alternative for treating various diseases.
