The competitive action of acetil-salicylic acid with respect to colinesterasi is demonstrated. The A. proposes a routine dose of this enzyme in the preparation for surgery with a high haemorrhage risk, such as tonsillectomy.
Complex formation between salicylic acid and adenosine or adenosine triphosphate in 0.2m phosphate buffer at pH=7 was investigated as a potential factor contributing to the prolongation of acetylsalicylic acid-induced GI blood loss. Spectrophotemetric techniques were used to evalute the
Buffered acetylsalicylic acid (Alka Seltzer, B-ASA) and plain aspirin (P-ASA) tablets were compared as to their effects on bleeding time and platelet function in eight healthy male volunteers. Two doses (500 and 1000 mg) of each preparation were investigated in a cross-over design, each volunteer
1 g acetyl salicylic acid orally significantly enhanced the initial rate of platelet aggregation induced by 1 mumol/l and 2.5 mumol/l ADP. Sodium salicylate was without effects on the platelet aggregation and specifically it did not prevent acetylsalicylic acid from inhibiting the secondary
1 In normal volunteers maximum reductions in platelet functions, collagen aggregation, adhesion and PF4 availability, were achieved using combined doses of 50 mg three times daily dipyridamole + 180 mg ASA or 75 mg three times daily dipyridamole + 120 mg ASA daily. 2 These doses did not prolong the
OBJECTIVE
The aim of this multicentre, randomized open trial was to compare the efficacy and tolerance of 4-ASA vs 5-ASA enemas in the treatment of distal moderately active ulcerative colitis. Fifty patients were randomized to receive enemas in 100 mL suspension of 4-ASA (2 g, n = 26), or 5-ASA (1
