Plasma Protein Level

Total plasma protein levels were determined for 292 female and 228 male American kestrels (Falco sparverius) in the wild. Plasma protein levels were significantly higher in females than in males, and higher during prelaying than during incubation. For both sexes, plasma protein levels did not vary significantly with the number of days before or after egg laying on which the sample was taken, time of sampling, prey abundance, age, molt, or infection by the blood parasite Haemoproteus sp. Protein levels in females increased with date of sampling and body condition during prelaying, while the same pattern was seen in males during incubation. With the exception of those of prelaying females, plasma protein levels increased with ambient temperature. The results of this study suggest that at least some of the variation observed in total protein levels is attributable to physical condition. However, further investigation is required before the reliability of using total plasma protein level as a tool to assess the health and condition of kestrels is known.

Plasma Protein Level

1. Experiments on five dogs are described consisting in the daily removal of blood plasma in amount from 25 to 100 cc. the red cells being returned to the circulation in Locke's solution. In no case was there a significant drop in plasma protein concentration. 2. A gravimetric method for the determination of total plasma protein is described. 3. A case is reported of cirrhosis of the liver in which over 10 gm. of protein daily was lost in the ascitic fluid during a period of 7 months without any lowering of plasma protein concentration. 4. The constancy of the plasma protein level and the adequacy of the mechanism of regeneration is pointed out.

The Difference

The rate of plasma protein turnover is more rapid in dogs receiving adequate dietary protein than when a diet devoid of protein is fed. Both albumin and combined globulins are involved in this change. The difference in turnover is reflected in a total protein half-life of 4.8 days with protein feeding versus 7.8 days without protein in the diet and in the metabolism of 1.0 and 0.65 gm. per kilogram of body weight per day on the respective diets. Additions of dietary protein from 10 to 30 per cent caused no further increase in the rate of plasma protein turnover. With protein depletion due to plasmapheresis and a very low protein diet there is evidence of reduced protein metabolism as indicated by nitrogen retention as well as a reduction in total plasma protein breakdown and interchange of isotope between plasma and tissue proteins. Following introduction of labeled plasma protein into the circulation the net amount of isotope transferred to tissues has been computed from the difference between total plasma protein breakdown and combined C14 excretion in urine and expired air. In animals receiving adequate dietary protein, tissue transfer amounts to 70 per cent of the total lost from the plasma proteins each day while the percentage rises to 85 in depleted dogs deprived of protein. In dogs with both plasma and tissue proteins labeled it can be estimated that, under conditions of protein feeding, an amount of C14 approximately equal to that lost from the plasma must recycle to account for the observed decrease in Apparent plasma protein turnover rate, (t½ of 15 versus 5 days). Without protein in the diet the isotope contribution of the tissues to the maintenance of plasma protein levels must be as great as or greater than that transferred in the opposite direction.

Plasma Protein Level

A non-splenectomized dog, on a vitamin-adequate basal diet, in the course of a plasmapheresis experiment, developed an uncontrollable anemia associated with the presence of bodies in or on the erythrocytes, indistinguishable from the descriptions of Bartonella canis. The normal plasma protein level of 7.3 per cent was reduced to 4.1 per cent by diet and the removal of 5354 ml. of whole blood in 33 bleedings. The Bartonella infection was transferred to a splenectomized dog by an intravenous injection of whole blood. Each animal was apparently sterilized by one injection of neoarsphenamine equivalent to 15 mg. per kilo weight. It is possible that the spleen liberates some substance into the blood stream which has an inhibitory effect upon a latent Bartonella infection and that this protective substance was diminished by the many bleedings associated with the lowering of plasma proteins in the non-splenectomized dog and was lacking in the inoculated splenectomized dog.

Thrombin generation, plasma antithrombin levels, and plasma protein levels were measured in dogs following rapid massive bleeding and transfusion. Three groups of four dogs per group were used. One group was transfused with saline, one with dextran, and one with a plasma fraction. The plasma fraction was prepared from mixed dog plasma by a procedure designed to remove most of the known clotting factors with a minimum of damage to other proteins. The in vivo dilution of blood by transfusion with two volumes of saline or one of plasma fraction increased the rate of thrombin generation. Dilution by transfusion with dextran decreased both rate and amount of thrombin generation. For the first few hours following transfusion with saline, plasma antithrombin increased more rapidly than total plasma protein. This was probably a result of increased lymph flow. Fluctuations in the coagulability of the blood were observed up to 72 hours following bleeding and transfusion. The fluctuations following saline transfusion were less prolonged than when dextran or plasma fraction was used.
