In 4 dogs injected intravenously (i.v.) with 125I labeled fibrinogen, 51Cr labeled platelets and 99mTc labeled albumin, and subjected to successively increasing amounts of i.v. infused monomethylmethacrylate, doses corresponding to the amounts released into the blood stream following implantation of acrylic cement during total hip replacements did not affect the clotting mechanism, did not cause trapping of platelets and fibrin in the lungs, did not generate fat emboli, and did not cause depression of the arterial oxygen tension or blood pressure. Monomethylmethacrylate in whole blood was associated with both blood cells and plasma.

In studying hemocoagulation in dogs under conditions of Frunze (760 m above the sea level) and Tuya-Ashu (3200 m above the sea level) it was shown that in the "emergency" phase of adaptation (the first three days) there was seen activation of fibrinolysin and profibrinolysin with depression of antifibrinolysins and inhibitors of profibrinolysin activators. The concentration of plasma fibrinogen at that period decreased by 100 mg%, which could promote an increase in the vascular permeability and improvement of oxygen approach to the tissues. Later, along with elevation of fibrinolysin and profibrinolysin activators there was a marked increase in the level of fibrinolysis inhibitors. Correlation of all the fibrinolysis components was established at a new level.

Certain physiologic and hematologic data were determined in ponies given Escherichia coli endotoxin by three routes: single IV dose, single intraperitoneal (IP) dose, and multiple IP boluses. In all ponies, the reaction was characterized by weakness, depression, peripheral circulatory abnormalities, and pyrexia. The pyrexia was more severe and was sustained in the ponies given multiple IP bolus endotoxin. Changes in packed cell volume, peripheral blood neutrophil, lymphocyte, and thrombocyte counts, and blood glucose were noticed in the three groups. Blood lactate and beta-glucuronidase values were determined and increases occurred only in the two IP endotoxin administration groups. A fibrinogen increase was observed in only the multiple IP bolus group. Attempts were made to correlate the lactate and beta-glucuronidase values with the severity and prognosis of the endotoxemia response. In general, the single IV bolus and, to a lesser extent, the single IP bolus endotoxin produced abrupt but transient responses. The multiple IP bolus endotoxin administration produced a more gradual and sustained response, which was more closely comparable with a clinical gastrointestinal disease problem than the other routes of administration produced.

An outbreak of chronic liver disease was investigated in a kennel of dogs. Anorexia, depression, polyuria, polydipsia, icterus and a terminal hemorrhagic diathesis were noted in clinically affected dogs. Thrombocytopenia, hypofibrinogenemia, elevated fibrinogen degradation products and prolonged activated partial thrombosplastin times (PTT) and one-stage prothrombin times (PT) were associated with the hemorrhagic crisis. Aflatoxicosis was confirmed by the presence of significant levels of aflatoxicosis was confirmed by the presence of significant levels of aflatoxin B in the commercial dog food being fed. A subacute hepatitis was found on necropsy. Disseminated intravascular coagulation was suspected as the cause of the hemorrhage in these cases and treatment was instituted.

Coagulation factor XIII and plasma fibrinogen chromatographic assays have been performed serially in patients suffering from acute myocardial and cerebral infarction, and in others with disseminated intravascular coagulation. The findings were compared with 2 groups of "controls"; normal clinically-well subjects and hospitalized patients with cerebral infarction who exhibited minimal, stable, or improving neurological deficits. Substantial depression of factor XIII concentrations developed in the 3 patient groups, together with concomitant significant increases in the proportion and concentration of plasma high molecular weight fibrin(ogen) complexes (HMWFC). An inverse correlation (p less than 0.05) between coagulation factor XIII concentration and percentage of HMWFC was demonstrated in the early stages of the illness. These findings suggest that depression of coagulation factor XIII concentration in these states, is secondary to extravascular or intravascular coagulation and may reflect its degree.

Oral contraceptive (OC) use has been associated with 50 different metabolic changes but few women require increased amounts of nutrients to prevent deficiencies. Plasma triglyceride levels are markedly increased by OCs, but no consistent changes have been found in plasma cholesterol, fatty acids, or phospholipids. Small elevations in blood glucose and plasma insulin levels result from OC use, and plasma albumin is decreased and the alpha and beta globulins and fibrinogen are increased. Women on the pill show slight increases in the urinary excretion of some of the amino acids and decreases in some of the blood amino acids. Tryptophan metabolism is altered by OC use; changes in parameters of Vitamin-B6 metabolism are seen and Vitamin-B6 is used as a cofactor for several enzymes in the tryptophan pathway. At the beginning of OC use the retention of dietary nitrogen increases, and weight gain may result. The estrogens in OCs reduce plasma calcium, phosphorus, and magnesium. Most studies demonstrate an increase in serum iron and copper and a decrease in plasma zinc. Studies have also found an increase in plasma levels of Vitamin-A and a decrease of carotene, Vitamin-E, ascorbic acid, folacin, Vitamin-B12, and Vitamin-B6. 20% of OC users have enlarged cervical and vaginal cells as a result of abnormal folacin metabolism. The abnormality is corrected by oral folacin supplementation. Some women respond to OC treatment with biochemical signs of Vitamin-B6 deficiency and depression. These women should receive 20-40 mg Vitamin-B6 as a supplement.

Plasma fibronectin (cold-insoluble globulin) is known to be cross-linked to fibrin during the final stage of blood coagulation and is probably the major nonspecific opsonin of blood. We measured the concentration of plasma fibronectin in 36 hospitalized patients (11 with malignancy, 12 with infection, 13 with other underlying diseases) with evidence of fibrin depostion and lysis. Plasma fibronectin concentration was greater than 2 S.D. below the mean of normals in 17 of the patients (p less than 0.001). Depression of fibronectin was not related to severity of disseminated intravascular coagulation, as assessed by fibrinogen concentration and the quantity of FDP in serum. Depressed plasma fibronectin concentration and the quantity of FDP in serum. Depressed plasma fibronectin concentration was an unfavorable prognostic finding, inasmuch as 12 of the 17 patients with depressed fibronectin concentrations died during hospitalization as compared to five of the 19 patients with normal fibronectin concentrations (p less than 0.02). We speculate that specific depletion of plasma fibronectin, because of codeposition with fibrin or due to increased utilization as a nonspecific opsonin, may contribute to the organ failure seen in severely ill patients.

When rats were given single or multiple doses of warfarin, the levels of prothrombin and factors VII, IX, and X were depressed, as expected. However, modest reductions of factors V, VIII, XI, and XII, but not of fibrinogen, also occurred. The levels of all eight factors promptly returned to normal when vitamin K1 was given. Warfarin-resistant rats had no depression of any of the eight factors. When vitamin K deficiency was induced by internal or external biliary fistula, factors II-VII-IX-X decreased sharply and factors V-VIII-XI-XII decreased modestly. Again, all depression were promptly reversed by vitamin K1. Isolated livers from warfarinized rats did not generate the classic vitamin K-dependent factors during 5 h of perfusion but did generate small amounts of factors V, XI, and XII, although less than normal. The isolated rat liver apparently does not generate factor VIII.

Twelve patients with acute, untreated inflammatory bowel disease (IBD) were followed prospectively for coagulation and platelet function. With no symptomatic coagulopathy, abnormalities were found in all patients. With acute diseases, elevations of fibrinogen (9/12), factor V (8/12), and factor VIII (6/12) were common. Depressions of antithrombin III levels were also observed acutely (8/12). Abnormalities of platelets were both quantitative and qualitative. Thrombocytosis was present (11/12), and abnormalities in the rate and percent platelet aggregation were seen (9/10). During therapy, factors V and VIII, antithrombin III levels, and the quantitative and qualitative platelet abnormalities returned towards normal in direct correlation with sedimentation rate and clinical disease activity.

Three cases are described showing a seasonal exacerbation of their nephrotic syndrome in association with an atopic trait and grass pollen allergy. The first patient has a history of four consecutive seasonal relapses each requiring steroid therapy. Following a course of desensitization injections he has now been free of relapse for 3 consecutive years. The second patient has also had a recurrent steroid-sensitive nephrotic syndrome often associated with the pollen season and allergic rhinitis. In this patient a course of cyclophosphamide has reduced his tendency to relapse. The third patient who has been on continuous prednisone therapy shows a seasonal increase in proteinuria. Serum changes in the first two patients include: a seasonal rise in total and grass pollen specific IgE; the continued presence of grass pollen specific IgG throughout the year but with a reduction during the pollen season in association with a more pronounced fall in the total IgG level; a depression in the C3 level in association with each major relapse; a mild rise in the I-K titre and a positive result in the Clq test for circulating complexes. A renal biopsy performed on the first patient when in relapse showed minor histological changes only and IgG, IgM, IgA, IgD, IgE, C3 and fibrinogen were undetectable by immunofluorescent examination. The probable mechanism for the development of proteinuria in these patients is discussed.
