    Notes: [Auszug] A normal thromboplastin generation test was carried out using normal absorbed plasma, serum and platelets but with the prior addition of a suitable concentration (0-85 unit/ml.) of heparin. Little thromboplastin was formed. If the addition of heparin to the normal mixture is delayed until 3 min. ...

    Notes: [Auszug] If a critical strength of an isolated phospholipid, active in the Stypven system, is added to platelet -poor plasma at 37 C. or 10 C. it is found that this activity has decreased at the end of 2 hr. (To 0-5 ml. of fasting platelet-poor plasma is added 0-5 ml. of a predetermined concentration of ...

    Notes: [Auszug] A gelatinous material was scraped off the cleaned endothelial surface of fresh human aortas and shaken in saline to give a thick suspension. It was shown histologically that this manoeuvre removed the endothelium from the aorta. It was frozen and thawed twice and examined as follows : To 0-1 ml. ...

    Notes: Polymers containing pendant mereaptan groups can be prepared by the reaction of copolymers containing a small amount of glycidyl methacrylate with an excess of thioglycolic acid. Two mercaptan groups are introduced for each original epoxide group. Chain transfer constants were determined for these groups with styrene and with methyl methacrylate and were found to be similar to those found with simple mercaptans. Free-radical polymerization of styrene, of acrylate, and of methacrylate monomers in solution at 60°C. in the presence of the pre-formed mercaptan-containing polymer produced graft copolymers in high efficiency through chain transfer with the highly active mercaptan sites. The efficiency of grafting was determined from extraction data and by titration of the residual mercaptan groups; the results generally agreed well with those predicted from the theory presented in the companion paper.
