An immobilized amino acid napbthylamide substrate for proteinases with tryptic-like specificity was prepared by reacting L-arginine P-naphthylamide with an N-hydroxysuccinimide-activated derivative of agarose. Hydrolysis of the immobilized substrate (AlO-Arg-PNA) was followed by monitoring the increase in fluorescence accompanying the release of /3-naphthylamine. Assays using AIO-Arg-PNA were d...

teolytic enzyme plasmin (fibrinolysin) is supposed to be present in normal blood plasma in an inactive form, called plasminogen (proplasmin). Anxiety, strenuous exercise, hemorrhage, burn , t rauma (‘ ‘tourniquet shock’ ‘) and epinephrine admmistration have heels found to produce increased fibrinolytic activity (plasmin formation) in the blood. 3 The physiologic mechanism of activation of propl...

FORMATION OF FIBRINOLYSIN FROM ITS INACTIVE PRECURSOR IN SERUM WAS OBSERVED UNDER THE FOLLOWING CONDITIONS: (a) by adding the specific antigen to serum from sensitized guinea pigs; (b) by mixing normal guinea pig serum with peptone, agar, hyaluronic acid, chondroitinsulfuric acid, glycogen, pneumococcal polysaccharides, and heparin. Activation of profibrinolysin by these agents differs from chl...

Rhinoplasty is one of the most common aesthetic procedures in the world. It is the most common aesthetic surgery procedure in Iran. Achieving complete patient satisfaction is almost impossible but improving the aesthetics and function of the nose is the aim of surgery. This report describes a 34 years old woman with a large bump in the tip of the nose after three times cosmetic rhinoplasties. T...

Staphylococcus aureus was found in 44% of the rectal swabs from 377 pigs and in 12% of the swabs from 147 cows. Seventy-one percent of the isolates from pigs showed fibrinolytic activity and grew in colonies of the negative violet type on crystal violet agar. In this group, 47% of the isolates coagulated both human and bovine plasmas and were characterized as intermediate type, whereas 24% coag...
