in order to determine the changes in serum and blood factors of rainbow trout following experimental infection with a pathogenic aeromonas hydrophila, the cause of haemorrhagic septicemia in fish, three groups of rainbow trout (10 fish in each group) were injected intraperitoneally with 105, 106 and 107 of this bacteria respectively. the same number of fish in a control group were injected simi...

A marked imbalance of the two light chain types of immunoglobulins was observed in two young male adults suffering from primary hypogammaglobulinemia and intrinsic factor-deficient pernicious anemia. In one patient, the i/A light chain ratio of serum immunoglobulins was 0.01; in the other it was approximately 6 (normal value, 1.8 ± 0.3). This light chain imbalance was found within each of the t...

The maternal immunoglobulins acquired through the colostrum play a significant role in the defense mechanism of lamb against neonatal diseases until its own immune system is primed and produces significant amount of antibodies. The absorption of these immunoglobulins from the intestine is maximum during first six hours of life and no absorption occurs 24-36 hours postpartum. Neonatal lambs with...

The purpose of this investigation was to study the distribution and levels of the following immunoglobulins, IgA, IgG, and IgM ,in sera and in some secretions of monkeys (M. fascicularis). IgG, IgA, and IgM were isolated from monkey serum and secretory IgA was separated from monkey milk by combined gel filtration and ion-exchange chromatography. These pure preparations served as standards to qu...

Acute renal failure is one of the side effects while using intravenous immunoglobulins. This complication is also observed with iodinated contrast media. Herein, we describe a patient with acute renal failure who received intravenous immunoglobulins and iodinated contrast media concomitantly. Both drugs are responsible for osmotic nephrosis. The same effect on renal cells may explain a synergis...
