SummaryTwenty-one rabbits were infused with 20μg/kg/hr of E. coli endotoxin for 6 hr. Eight of the animals were preinjected immediately before the infusion of endotoxin, with a bolus dose of human AT III calculated to increase the antithrombin content of the plasma by about 4 units/ml. All eight animals which were preinjected with AT III survived, while 5 of the 13 control rabbits infused with endotoxin alone died. The changes in coagulation parameters from the baseline values, between the 8 control rabbits which survived and the 8 animals which were preinjected with AT III were compared. The concentration of the preinjected human AT III declined significantly faster (P: <0.01) than that of the native rabbit AT III. AT III prevented the decline of F.XII throughout the infusion of the endotoxin. However, the decline in F.V, fibrinogen, prothrombin and platelets was not affected (P: >0.5) by the injection of AT III.

SummaryPre- and postoperative plasma levels of Prothrombin Fragment 1 + 2 (F1+2), Thrombin-antithrombin III complex (TAT), Fibrinopeptide A (FpA), Fibrin and Fibrinogen Degradation Products (FbDP, FgDP) and Soluble Fibrin (SF) were measured in 40 patients undergoing gastric surgery in order to compare patients operated for benign (n = 21) and malignant (n = 19) disease. Plasma levels of F1+2, TAT, FbDP and SF on the first postoperative day were significantly higher than before operation. F1+2 and FbDP levels were further increased one week after surgery, at which time FgDP levels were also higher than preoperatively. A significant postoperative increase in FpA levels was found only in patients with malignant disease. When age was taken into consideration, significant differences between patients with and without malignancy were found only in the late postoperative period, as cancer patients had higher FpA and FbDP levels one week after surgery and higher FbDP levels one month after discharge from hospital.

SummaryBased on gelfiltration studies, the part of AT III which becomes bound to thrombin during the process of in vitro blood coagulation was calculated to be about 40% of total AT III. Complexes consisting of one AT III and one thrombin molecule could not be detected while fractions corresponding to molecular weights of about 190,000 Dalton show AT III as well as thrombin activities. The AT III - thrombin complex in normal human serum consists, therefore, of either 2 AT III and 2 thrombin molecules or of one AT III and 4 thrombin molecules.

SummaryAntithrombin III (AT III) plasma levels were investigated in 18 full term neonates and 14 healthy preterm neonates. A control group of 20 healthy adults was also studied. AT III was measured as antigen concentration (Ag) and antithrombin or anti-factor Xa heparin cofactor (H. C.) activities. Crossed immunoelectrophoresis on heparin-agarose (H-CIE) was carried out on plasma samples; moreover the distribution of isoantithrombins was investigated on whole plasma by a technique of crossed immunoelectrofocusing (CIEF). AT III plasma levels in full term infants were significantly lower as compared to the adult values. The preterm newborns group showed a further significant decrease in AT III levels as compared to the full term neonates. In all infants AT III H-CIE runs displayed a single fast moving anodal peak, so that a normal binding to heparin was demonstrated. The CIEF AT III plasma pattern of the adults as well as of all neonates displayed three major peaks at pH range 5.2-4.9, a small amount of AT III at pH 4.9-4.8 and a minor peak at pH 4.8-4.6, so that it was concluded that the isoantithrombins plasma distribution in neonatal age is identical to that of the adult subjects. Four neonates whose mothers were affected by AT III congenital defect were also investigated: diagnosis of congenital deficiency was established in three cases.

Antithrombin Iii Activity

It is known that antithrombin III (AT III) is the main inhibitor of blood coagulation. It inactivates thrombin and activated × factor. Heparin increases the AT III activity in vitro as well as in vivo. The authors have studied the AT III activity in sera of 30 pregnant women, at term, before labour started (2–24 hrs) and 30 as well as 60 min after the birth of placenta and daily for five days after delivery. The AT III activity was determined using the modified method of Gerendas. Out of the 30 women 15 were given 5000 IU heparin subcutaneously 1½—2 hours before delivery. In the 15 women with no heparin treatment AT III activity of serum significantly decreased after birth of placenta compared with the predelivery value and became normal on the fifth postpartum day. Heparin given subcutaneously prevented development of this decrease.
