[Characteristics of anaphylaxis in fasting rats].

The effect of 4-day fasting was studied in male Wistar rats (200-150 g) sensitized by ovalbumin on anaphylaxis manifestations in vivo, antigen-dependent histamine secretion by mast cells in vitro, concentration of serum specific IgG antibodies. The fasting ended by a shocking allergen dose. It is shown that in the condition of food deprivation anaphylactic severity significantly lowered as well as antigen-dependent histamine secretion by mast cells. No changes were seen in the levels of specific antibodies in the serum.
