Abstract: A non-stoichiometric perovskite oxide having the general chemical formula LaXMnOY, in which the molar ratio of lanthanum to manganese (“X”) ranges from 0.85 to 0.95, can be used in particle form as an oxidation catalyst to oxidize NO to NO2 in an exhaust aftertreatment system for a hydrocarbon-fueled engine. The oxygen content (“Y”) fluctuates with variations in the molar ratio of lanthanum to manganese but generally falls somewhere in the range of 3.0 to 3.30. The crystal lattice adjustments spurred by the non-stoichiometric molar ratio of lanthanum to manganese are believed responsible for an enhanced NO oxidative activity relative to similar perovskite oxides with a higher molar ratio of lanthanum and manganese.

Infusion of nitrite iv caused an acute drop in resting energy expenditure (oxygen consumption) and nitrate, when given perorally, caused a drop in oxygen consumption during exercise and a depression of the increase in blood glucose observed after an oral glucose tolerance test. The doses of nitrate and nitrite did not cause any detectable change in methemoglobin levels of blood. Also, nitrate and nitrite did not alter lactate levels in blood. This discovery provides useful treatments to regulate the energy expenditure and glucose homeostasis of a mammal by administration of inorganic nitrite and/or nitrate.
