25. Platelet factor 3 in normal subjects and patients with renal failure
Two tests were used to differentiate abnormalities in release of platelet factor 3 (PF3) from quantitative deficiencies of this factor in normal subjects and in patients with renal failure. The first test was an assay which determined availability of PF3 (PF3-A time) and involved the use of a mixture of patient's platelet-rich plasma (PRP) and normal platele

26. Safe per-operative anticoagulation
Pre-, per-, and post-operative anticoagulation at the therapeutic level is nowadays the most, if not the only, available effective method to prevent post-operative thrombo-embolism. There is no increased tendency to bleeding to be feared during the operation. The real danger of this prophylaxis consists of a treacherous tendency to acute relative overdosage

27. First trimester fetal diagnosis of genetic disorders: clinical evaluation of 250 cases.
Chromosome and enzyme determinations were performed in 250 pregnancies between the 7th and the 12th week of gestation. The majority of the tests were performed for risk of chromosomal abnormalities and 75% of the women were 35 years old or more. We describe a chorionic villi sampling (CVS) technique which proved to be highly efficient, with a diagnostic succ

28. Preservation of hemostatic and structural properties of rehydrated lyophilized platelets: potential for long-term storage of dried platelets for transfusion.
Currently, therapeutic platelet concentrates can be stored for only 5 days. We have developed a procedure that permits long-term storage of fixed and lyophilized platelets that retain hemostatic properties after rehydration. These rehydrated lyophilized platelets (RL platelets) restore hemostasis in thrombocytopenic rats and become incorporated in the hemost

29. Fibrinogen Bethesda: a congenital dysfibrinogenemia with delayed fibrinopeptide release
A dysfibrinogenemia (fibrinogen Bethesda) was detected in a 9 yr old male of Mexican-English extraction who had a lifelong history of mild bleeding diathesis. The prothrombin and partial thromboplastin times were moderately prolonged; the thrombin and Reptilase times were markedly prolonged. The plasma fibrinogen level was normal by conventional methods but

30. Hereditary deficiency of the sixth component of complement in man. II. Studies of hemostasis.
Prompted by previous observations of defective blood clotting in rabbits deficient in the sixth component of complement (C6), an evaluation was made of the hemostatic functions of the homozygous proband of a newly recognized human kindred with hereditary C6 deficiency. This human subject, who had no clinical evidence of a bleeding disorder, exhibited a total

31. Survival from hepatic transplantation. Relationship of protein synthesis to histological abnormalities in patient selection and postoperative management.
Forty-one patients, all in end stage hepatic failure, underwent 46 liver transplantations with a long-term survival rate of 63%. Six patients died of uncontrollable bleeding due to primary graft malfunction at or immediately after operation. Nine died early or late with overwhelming infection. In addition to clinical assessment, needle liver biopsy, central
