Factors affecting human tolerance to sustained acceleration.
Linear increases in G tolerance with increases in anti-G suit (AGS) bladder inflation pressure occurred when relaxed subjects were exposed to acceleration plateaus while riding a centrifuge and were either seated upright, (15 degrees seat back angle or SBA) or supine (60 degrees SBA). Supine G tolerance with AGS bladder inflation decreased as G onset time was increased by factors of two and fou...
متن کاملEffect of Hypothermia on the Tolerance of Dogs to Digitalis
H modifies to a considerable degree the effects of various drugs. Among those investigated in the past have been central nervous system stimulants and depressants, hormones, epinephrine, acetylcholine, insulin, thyroid, ethyl alcohol, Dicumarol, oxygen, carbon dioxide, procaine, and cocaine. However, the effect of hypothermia on the action of digitalis has not been extensively investigated. Mos...

متن کاملEndogenous digitalis-like factors. An historical overview.
The sodium pump is a ubiquitous cell surface enzyme, a Na/K-ATPase, that maintains ion gradients between cells and the extracellular fluid. The extracellular domain of this enzyme contains a highly conserved receptor for a plant-derived family of compounds, the digitalis glycosides, used in the treatment of congestive heart failure, and certain cardiac arrhythmias. The concept that an endogenou...
متن کاملAn evaluation of digitalis tolerance with acetyl strophanthidin.
The determination of the state of digitalization in a given patient is often difficult and at times impossible. Although Eggleston1 indicated that the required quantity of digitalis is a function of body weight, the digitalizing dose is an empiric and occasionally a dangerous assumption. Clinically, the classical symptoms of digitalis intoxication may mimic those of circulatory failure. Nausea,...
