Blood Flow in the Human Calf during Tobacco Smoking.
THE cutaneous vasoconstrictive effect of tobacco smoking has been demonstrated by several groups.1-4 In about 50 per celit of people, smoking has been reported to diminish the increase in foot blood flow, called reactive hyperemia, which follows a period of arterial occlusion. Experiments on patients with sympathectomized limbs showed that the decrease in reactive hyperemia was mediated through...
متن کاملThe Effect of Tobacco Smoking on Gingival Crevicular Fluid Volume
OBJECTIVES The negative effects of smoking on periodontal health are well known. But the mechanism is not clear yet. The aim of the present study is to investigate the effects of smoking on gingival crevicular fluid (GCF) volume. METHODS The study included 26 age and gender matched periodontally healthy males. Half of the participants were smokers and the others were non-smokers. After period...
متن کاملSkin cooling maintains cerebral blood flow velocity and orthostatic tolerance during tilting in heated humans.
Orthostatic tolerance is reduced in the heat-stressed human. The purpose of this project was to identify whether skin-surface cooling improves orthostatic tolerance. Nine subjects were exposed to 10 min of 60 degrees head-up tilting in each of four conditions: normothermia (NT-tilt), heat stress (HT-tilt), normothermia plus skin-surface cooling 1 min before and throughout tilting (NT-tilt(cool)...
متن کاملBlood carboxyhaemoglobin changes during tobacco smoking.
Using multiple samples collected via an indwelling venous cannula changes in blood carboxyhaemoglobin (COHb) were studied in five subjects before, during and up to 24 hr after smoking. On average the smoking, with inhalation, of one cigarette in 64 min raised the % COHb by 1-6, compared with 2-2 for 24 min of inhaled cigar smoking and only 0-2 for 20 min of non-inhaled pipe smoking. It is sugge...
متن کاملRegional cerebral blood flow responses to smoking in tobacco smokers after overnight abstinence.
OBJECTIVE The purpose of the study was to determine the effects of cigarette smoking on brain regional function in a group of chronic smokers by using cerebral blood flow (CBF) measures and positron emission tomography (PET). METHOD Nineteen tobacco smokers were studied after about 12 hours of smoking abstinence. Regional CBF (rCBF) measures were obtained with PET and [15O]H2O in six consecut...
