The antigenic properties of normal 19S gamma-globulin, pathologic macroglobulins, beta(2A)-myeloma proteins, and Bence Jones proteins have been compared with 7S gamma-globulin and the small 3.5S units derived from it by gel diffusion precipitin techniques. These studies demonstrate that the determinant groups on the 7S gamma-globulin molecule responsible for the cross-reaction with each of the ...

Immunofluorescence and fluorescent microscopy permit the demonstration of fixation of antibody, previously made fluorescent, on a specific antigen. A direct technic reveals the antigen to which globulins representing the antibodies of immune serum, previously conjugated with a fluorescent substance, are fixed. An indirect technic makes use of antihuman globulins developed in rabbit sera and mad...

Passive anaphylaxis of the guinea pig has been subjected to numerous immunological studies (1). They have established for both systemic (2) and cutaneous anaphylaxis (3) the levels of specific antibody required, and the need for a latent period of sensitization (4, 5) which is generally believed to be the time required for the binding of the antibody to tissue receptors. Further evidence for an...

Masawe, A. E. J., and Rwabwogo-Atenyi, J. (1973). Archives of Disease in Childhood, 48, 927. Serum protein and transferrin determinations to distinguish kwashiorkor from iron deficiency anaemia. Serum proteins and serum transferrin levels were studied in 38 African children of whom 10 were normal controls, 18 had severe iron deficiency anaemia, and 10 had kwashiorkor. The results showed that th...

The level of protein-bound hexoses was compared in several fractions of electrophoretically separated globulins in the sera of normal and wounded rats. Changes in the concentration of protein components which were not apparent from the amount of total protein of different fractions could be identified. Although wounding resulted in no change from the normal protein level of one a-globulin fract...

The objective of this study was to determine reference intervals for plasma protein fractions of normal appearing, wild Atlantic loggerhead sea turtles, Caretta caretta. Blood was collected into heparinized vacutainer tubes from the following groups of turtles: 1) ten adult males; 2) eleven adult females; 3) ten juvenile males; and 4) ten juvenile females. Plasma was removed and total protein c...

The aim of this study was to evaluate the effect of the season (ambient temperature and relative humidity) on some blood metabolites in dairy cows during postpartum period. Blood samples were collected from 195 clinically healthy dairy cows of 8 Italian dairy herds in spring (April-May 15.5±4 °C and 69.5±0.7 %), summer (June-July 23±1.5 °C and 69±1.3 %) and autumn (September-October 17±2 °C and...
