FAA was administered orally to adult rats at 1\/2 LD<jats:sub>50<\/jats:sub> and subcutaneously to infant rats at LD<jats:sub>100<\/jats:sub> or 1\/10 LD<jats:sub>50<\/jats:sub>. Electrocardiogram (ECG), respiration and motor activity were registered for 7 days. Clinical analysis of ECG and the heart rate variability (HRV) was carried out to assess the state of the vegetative nervous system.<\/jats:p><jats:p>In adult rats, FAA caused marked disturbances in the activity of cardiovascular and respiratory systems, including the development of a potentially lethal acute cor pulmonale. Conversely, there were no significant changes of cardiac function and respiration in infant rats; they died because of extreme emaciation accompanied by retardation of development. In adult rats, bursts of associated cardiac and respiratory tachyarrhythmia, as well as regular high amplitude spasmodic sighs having a deca\u2010second rhythm were observed. In both infant and adult rats, FAA caused short\u2010term enhancement of humoral (metabolic) and sympathetic activities, followed by a gradual and stable predominance of parasympathetic influence on HRV. Under conditions of FAA inhibition of the tricarboxylic acid cycle, the observed physiological reactions may be explained by activation of alternative metabolic pathways. This is also supported by a lack of ontogenetically caused inhibition of spontaneous motor activity in infant rats poisoned with FAA, which highlights the significance of the alternative metabolic pathways for implementation of deca\u2010second and minute rhythms and a lack of a rigid dependence of these rhythms upon activity of neuronal networks.
