Urinary catecholamine excretion and blood sugar response during acute poisonings with dinitrobenzenes.
Rats were injected intraperitoneally with 0.015 mmol of p-dinitrobenzene/kg, 0.15 mmol of m-dinitrobenzene/kg and 0.45 mmol of o-dinitrobenzene/kg body wt. The dinitrobenzenes induced methaemoglobin concentrations of 86%, 60% and 49%, respectively, as well as increases of urinary catecholamine excretion and blood sugar concentration. Due to hyperglycaemia the glycolysis may be stimulated as mechanism for energy production in methaemoglobin-induced oxygen deficiency and as mechanism for reduction of methaemoglobin, that means as responses favouring survival after poisoning.
