| Abstract: | Effects of intravenous Y. pestis mouse toxin (LD50) injection on glucose, lactate glucagon, insulin blood levels and cAMP liver content in dynamics of intoxication development were studied. Hypoglycemia, observed 2 hours after toxin administration seems not to be due to the enhanced glucose utilization in peripheral tissues because insulin blood level during this period was decreased and lactate concentration has not been changed. Glucagon content by 2-5 hour of shock was strong elevated. Proposal is made that Y. pestis mouse toxin might induce carbohydrate metabolism alterations via direct liver glucose synthesising enzymes inhibition rather than cAMP-dependent glycogenolysis and gluconeogenesis regulation disturbances in this organ. |
