[Experimental reproduction of lactic acidosis in the pony].
One pony has been subjected to the intravenous injections of L-lactic acid. Two other ponies have been trained to intracaecal administration of L-lactic acid or sucrose. The obtained results show that: Intravenous injection of lactic acid increases the concentration of histamin and lactic acid, decreases the level of magnesium and reduces the pressure of carbon dioxide in the blood (the control animals and the treated animals) without the clinical symptoms of lactic acidosis. Intracaecal administration of lactic acid induces a high liberation of histamin in the caecum (the control animals and the treated animals), however, the level of histamin in the blood is not modified. Intracaecal administration of sucrose decreases pH and increases the concentration of lactic acid in the caecum, although, in this case, the accumulation of histamin in the caecum appears only in the non-fasting ponies, the starved animals, and the fed animals, which suggests the necessity of food's proteins for histamin synthesis.
