P172 THE NEUTROPHIL RESPIRATORY BURST IS GENERALLY PRESERVED IN CROHN'S DISEASE, BUT DIMINISHED BY CIGARETTE SMOKING

Socioeconomic Status and Current Cigarette Smoking Status: Immigrants’ Diminished Returns

Introduction: Although socioeconomic status (SES) resources influence population and individual health behaviors, socially marginalized groups gain significantly less health from their SES indicators, such as education and income, compared to the socially privileged groups. This pattern is called marginalization-related diminished returns (MDRs). However, most of the MDRs liter...

Hepatocyte growth factor stimulates neutrophil degranulation but not respiratory burst

Neutrophil function is regulated in part by cytokines with growth factor activities for different cell types. Hepatocyte growth factor (HGF) is a cytokine produced during injury to the liver and other organs. Neutrophils are numerous in such tissue injury sites and may be influenced by HGF. In the present study the effect of HGF on neutrophils was investigated. The data show that HGF at 1-10 ng...

the respiratory exchange ratio is higher in older subjects, but is reduced by aerobic exercise training

The hematologic effects of cigarette smoking in healthy men volunteers

Substances existed in tobacco smoke including carcinogens, alkaloids (mainly nicotine), irritants of the respiratory tract and carbon monoxide are known responsible for a wide range of diseases and disorders. The current study was designed to investigate the hematologic effects of smoking. This study is an observational, cross-sectional investigation in which the peripheral blood erythrocytic a...

Detrusor expulsive strength is preserved, but responsiveness to bladder filling and urinary sensitivity is diminished in the aging mouse.

The prevalence of urinary symptoms increases with age and is a significant source of distress, morbidity, and expense in the elderly. Recent evidence suggests that symptoms in the aged may result from sensory dysfunction, rather than abnormalities of detrusor performance. Therefore, we employed a pressure/flow multichannel urethane-anesthetized mouse cystometry model to test the hypothesis that...
