The main events caused by anaphilaxis in selenium haemostasis in rats include significant increase of selenium excretion with urine (6.36 +/- 1.18 nM Se/18 h., n = 10, compared with 1.72 +/- 0.38 nM Se/18 h., n = 10) and decrease of selenium plasma/selenium erythrocytes ratio from 0.939 to 0.791. Reduced glutathione (G-SH) administration led to 1.5-fold decrease of plasma selenium level and 1.3-fold increase of selenium concentration in intestinal walls of sensitized rats (r = -0.720, P < 0.001). Chromatographic separation of plasma proteins showed that intragastric intubation of G-SH to sensibilized rats significantly decreased the protein P content and did not influence the concentration of Se-GSHPx, thus indicating the local selenium acceptor role of G-SH...

In this paper we outline the importance or the histamine in the genesis of cardiac arrhythmias. Such an event can verify not only in patients with allergic diseases especially versus specific substances (antibiotics and anesthetics), but also after endoscopy of surgery which make free a large amount of histamine. For this reason, we outline the possible evenience anaphilaxis after coronarography or cardiac surgery with extracorporeal circulation. Therefore it is always very important to modulate the histamine tone to avoid arrhythmias which can be serious...

Mast cells and their chemical mediators play a role in cardiac and systemic anaphilaxis. Perivascular and cardiac mast cells have been implicated in the pathogenesis of coronary artery spasm, atherosclerosis, myocardial ischemia, and cardiomyopathy. Despite this, nothing is known about the immunological and biochemical characteristics of the human heart mast cell (HHMC). We have isolated and partially purified HHMC and compared them with mast cells isolated from lung (HLMC) and skin (HSMC) tissues. Cross-linking of the high-affinity receptor for IgE (Fc epsilon RI) by a polyclonal anti-Fc epsilon antibody caused the release of preformed (histamine and tryptase) and de novo synthesized mediators [peptide leukotriene C4 (LTC4) and prostaglandin D2 (PGD2)]...

The aim of this work was to study the effect of lymphocytes from individuals infected with Trypanosoma cruzi (Chagas' patients) on the contractile behaviour of living heart tissue. Chagas' lymphocytes (ChL) reacted with isolated rat atria preparations increasing the isometric development tension (IDT) and frequency of contractions (FC) in a dose-dependent manner. The maximal stimulatory effect was reached after 30-40 min of contract. In contrast, normal lymphocytes (NL) did not alter the basal IDT and FC values...

Eosinophil leukocytes migrate from the blood to the uterus under estrogen stimulation, redistribute through uterine extravascular compartment, degranulate in the organ, and release agents that are involved in several parameters of estrogen action. Agents that induce blood eosinopenia, block their migration to the uterus, interfere with their redistribution within the organ or modify their degranulation, selectively interfere with eosinophil-mediated responses to estrogen. The present study investigated whether ketotifen, an antiallergic agent that inhibits allergen-induced eosinophil degranulation, interferes with estrogen-induced eosinophil migration to the uterus and their subsequent degranulation...

Drug alergy is always a risk in Therapeutics. Penicillin allergy although less frequent than usually though, is very important because sometimes is life threatening. Penicillin allergy is an immunological phenomenon, it is possible to use in vitro and in vivo procedures able to demonstrate individual ability to develop allergical reaction, in particular to predict such severe reactions like anaphilaxis. This paper review current concepts regarding immune mechanisms for Penicillin allergy and immunological testing useful in its study...
