[Changes of anaphylactic sensitivity to some food proteins and aflatoxin B1 in guinea pigs].

The study was made of aflatoxin B1 effect on guinea pig alimentary anaphylaxis to chicken ovalbumin (CO) and pasteurized cow milk (PCM), of CO-specific IgG antibody levels, some serum indices, sensitivity of the animals to LD50 histamine. In response to aflatoxin B1 alimentary anaphylaxis both to CO and PCM became more severe, lethality of the anaphylaxis to CO being in logarithmic relation to aflatoxin B1 dose (p < 0.05); specific IgG-antibodies to CO grew in number; serum total protein increased against unchanged levels of albumins; the activity of gamma-glutamyltransferase inhibited; histamine shock gained severity, its lethality being logarithmically related to the aflatoxin B1 dose. The discussion covers mechanisms underlying the animal allergic reactivity responses to aflatoxin B1.
