BACKGROUND AND PURPOSE Immune and inflammatory responses, mediated by cytokines, play important roles in the pathophysiology of asthma. These responses are associated with over expression of T helper (Th)-2 cytokine, particularly interleukin (IL)-4 and IL-5, and decreased expression of Th-1 cytokine, IL-2 and IFN-γ. We hypothesized that there would be an(More)
The natural killer (NK) cells have distinct receptors called killer cell immunoglobulin-like receptors (KIR) which are responsible for regulating NK cell responses to infections and malignancy. The extensive variations in the number and type of KIR genes can be used as a tool to understand the differentiation of populations and also for tracing genetic(More)
The authors studied the prevalence of the human leukocyte antigen (HLA) Class I gene in 136 (85 male, 51 female) India-born schizophrenia patients residing in and around the Siliguri subdivision of West Bengal by the PCR-SSP method. The control group consisted of 150 age- and sex-matched healthy individuals from the same ethnic group as the patients.(More)
The effect of in vitro exposure of human erythrocytes to micromolar concentrations of hydroquinone and copper simultaneously on oxidative status-related biochemical parameters was studied. Hydroquinone is a component of cigarette smoke and serum copper level is increased in smokers. Copper forms a complex with hydroquinone and enhances its auto-oxidation to(More)
