Abstract
Observations made of the influence upon the blood volume of various cardio-tonics injected during the feverish course in typhoid and paratyphoid cases have proved that : (1). Total blood volume generally decreases 40-60 minutes after intravenous injection of 5.0cc of Digitamin, or, 30-40 minutes after intravenous injection of 0.13-0.075mg of Uabanin (g-Strophantin), and, the effectiveness by the latter is found especially much distinct. (2). Tatal blood volume is found increased as a rule 20-30 minutes after subcutaneous injection of 4.0cc of Spiramin, which does, however, cause it decreased on the contrary when the total blood volume has unusually been on the actual increase beforehands.
