The problem of the participation of the nervous system in the pathogenesis of anaphylactic shock has been the focus of attention of many researchers. Despite the large number of works, a consensus on this issue has not yet been reached. It is known that isolated organs of a sensitized animal can react to an antigen much more strongly than organs of a non-sensitized animal. By isolating the uterus, a piece of intestine, etc., we separate the latter from the central system and by this we judge that an anaphylactic reaction can proceed without the participation of the nervous system. At the same time, we forget two provisions: first, that the reaction of smooth muscles in isolated conditions differs in many respects from the reaction of the whole organism and, second, that these isolated organs contain elements of the autonomic nervous system in the form of fibers and nerve endings and peripheral ganglion cells. Therefore, we believe that the data obtained on isolated organs cannot serve as evidence of the passivity of the autonomic nervous system in anaphylactic shock, the participation of the latter should be studied on the whole organism. We have published our experimental data on the participation of the nervous system in the pathogenesis of anaphylactic shock. In this work, we tried to establish the importance of the nervous system in the reaction of smooth muscles in the whole organism, which is given a dominant role in the pathogenesis of anaphylactic shock.

The last 20 years have seen an explosion in our knowledge of the autonomic nervous system and our ability to manipulate its parasympathetic and sympathetic portions pharmacologically to achieve therapeutic goals. This article will briefly review the structure and function of the autonomic nervous system, with particular focus on the sympathetic branch. Included in the review is a discussion of the major receptors of the sympathetic system, concentrating on their intracellular mechanism of action, their effects on major target organ systems, and some commonly used pharmacologic agents that influence these organ systems through their actions on sympathetic receptors. Structure and Function of the System The autonomic (or involuntary) nervous system innervates the heart, visceral organs, blood vessels, smooth muscles, and glands. It can be divided functionally into the parasympathetic and sympathetic systems, which have opposing functions. All autonomic nerve pathways consist of two nerves in sequence. Presynaptic nerves begin in the central nervous system and transmit impulses to the postsynaptic nerves. Postsynaptic nerves then carry impulses to the effector organ. Actions of the parasympathetic nervous system include bradycardia, vasodilation in skeletal muscle and skin, contraction of bronchial smooth muscle, increased gastrointestinal motility, pupillary miosis, and contraction of the bladder detrusor coupled with relaxation of the bladder trigone (necessary for spontaneous voiding).

AbstractThe autonomic nervous system controls the smooth muscles of the internal organs, the cardiovascular system and the secretory function of the glands and plays a major role in the processes of adaptation. Heart rate variability is a non-invasive and easily applicable method for the assessment of its activity. The following review describes the origin, parameters and characteristics of this method and its potential for evaluation of the changes of the autonomic nervous system activity in different physiological and pathological conditions such as exogenous hypoxia, physical exercise and sleep. The application of heart rate variability in daily clinical practice would be beneficial for the diagnostics, the outcome prognosis and the assessment of the effect of treatment in various diseases.

The autonomic nervous system and especially the intracardiac autonomic nervous system is involved in Chagas' disease. Ganglionitis and periganglionitis were noted in three groups ofpatients dying with Chagas'disease: 1) Those in heart failure; 2) Those dying a sudden, non violent death and; 3) Those dying as a consequence ofaccidents or homicide. Hearts in the threegroups also revealed myocarditis and scattered involvement of intramyocardial ganglion cells as well as lesions of myelinic and unmyelinic fibers ascribable to Chagas'disease. In mice with experimentally induced Chagas' disease weobserved more intensive neuronal lesions of the cardiac ganglia in the acute phase of infection. Perhaps neuronal loss has a role in the pathogenesis of Chagas cardiomyopathy. However based on our own experience and on other data from the literature we conclude that the loss of neurones is not the main factor responsible for the manifestations exhibited by chronic chagasic patients. On the other hand the neuronal lesions may have played a role in the sudden death ofone group of patients with Chagas'disease but is difficult to explain the group of patients who did not die sudderly but instead progressed to cardiac failure.
