Response of fibrinolytic activity to venous occlusion.

Response of fibrinolytic activity to venous occlusion.

Resting fibrinolytic activity and the response of the fibrinolytic system to venous occlusion were studied in a group of healthy middle-aged men. All subjects showed increased fibrinolytic activity but of varying degrees. There was a linear relationship between resting and occluded levels of fibrinolytic activity but many subjects with lower levels of fibrinolytic activity showed an anomalous r...

Fibrinolytic Response to Standardized Venous Occlusion in Different Age Groups

The purpose of this study was to find out the range and distribution of fibrinolytic response to standardized venous occlusion in healthy volunteers and to determine whether there were any differences according to age and sex. In 118 healthy volunteers (55 males, 63 females) of various age groups, the total fibrinolytic activity in euglobulin fractions was measured by a well controlled fibrin p...

Effect of local exercise and vessel occlusion on fibrinolytic activity.

Arterial occlusion of the upper limb did not affect the fibrinolytic activity in the venous blood of that limb; venous occlusion associated with venous distension resulted in a marked rise in activity. Local fibrinolytic activity was increased substantially by active exercise; passive exercise induced a smaller increase. Active exercise undertaken during arterial occlusion did not result in a r...

Increased fibrinolytic activity in venous blood of hemiplegic limbs.

Fibrinolytic therapy and deep venous thrombosis.

SIR,-Further to the interesting leading article "Nutrition and Sleep" (20 May, p. 418) one may ask whether sleep is not the "natural" state and wakefulness merely a res,pite for the satisfaction of instinctual (and socially inculcated) drives. The hibernating animal is unlikely to chance upon dangerous predators. On this model the satisfqction of drives would lead to sleep and their continued f...
