Peritoneal dialysis related peritonitis: insights from a long-term analysis of an Italian center.

Background: Peritonitis is a common and severe complication of peritoneal dialysis (PD). For comparative analysis standardized definitions as well as measurements and outcomes are crucial. However, most PD-related peritonitis studies have been using heterogenous definitions and variable methods to measure outcomes.

[The mechanisms of the influence of the thalamic nuclei on the heart].

A major part of the ventromedial hypothalamus and the solitary tract nucleus in realisation of the thalamic effects on the heart, was revealed in rabbits. The polychemosensitive organisation of the thalamic neurons prompts specific functional shifts in the myocardium.

[Various mechanisms of neural regulation of the excretory and secretory functions of the stomach].

Activation of the brainstem RF with small doses of aminasine increases the gastric secretory and excretory functions in dogs. Changes in these functions following bilateral vago-and splanchnicotomy suggest the gastric vagal nerves to be related both to the secretory and excretory functions. The vagal and celiac nerves are supposed to alter the permeability of the gastric glands as well.

[Mechanism of the effect of the ventromedial, paraventricular and dorsomedial nuclei of the hypothalamus on the heart].

The influence of electrical stimulation of ventromedial, paraventricular and dorsomedial nuclei of the hypothalamus on polycardiographic data and on the serotonin level in the blood was studied in anesthetized rabbits as well as the unit activity of the above nuclei. The nuclei of the hypothalamus seem to be involved in the change of the myocardium functional state. The role of the serotonin content change in the blood was shown in making these nuclei influence the heart.
