Abstract:
Gaseous transmitters were assayed in rat blood during catecholamine-induced damage to the heart. Hypercatecholaminemia was modeled by single subcutaneous injection of 0.1% epinephrine hydrochloride in a dose of 2 mg/kg. The blood concentrations of NO, H2S, and CO were measured. The catecholamine-induced damage to the myocardium resulted in phasic changes in the blood levels of gaseous transmitters: CO concentration increased in 1 h, H2S increased in 24 h, and NO concentration increased in 72 h after injection.

Homogeneous Equilibria for Gaseous Reactions
For gas-phase reactions, the equilibrium constant may be expressed in terms of either the molar concentrations (Kc) or partial pressures (Kp) of the reactants and products. A relation between these two K values may be simply derived from the ideal gas equation and the definition of molarity. According to the ideal gas equation:
Respiration and Gaseous Exchange
Respiration involves the exchange of gases, especially oxygen (O2) and carbon dioxide (CO2), between the alveoli and body cells, a process facilitated by blood circulation. As a result, the cardiovascular system, which involves...
