Agonistic action of thrombin and endothelin-1 on vascular and bronchomotor tone in pig

To evaluate the role of thrombin and the involvement of endothelin-1 (ET-1) in regulation of bronchomotor and vascular tone, we used 18 anaesthetised, mechanically ventilated pigs, divided into three groups. Group 1 (n = 6) was treated with E. coli LPS (20 microng/kg/h for 180 min); group 2 (n = 6)...

Abstract To evaluate the role of thrombin and the involvement of endothelin-1 (ET-1) in regulation of bronchomotor and vascular tone, we used 18 anaesthetised, mechanically ventilated pigs, divided into three groups. Group 1 (n = 6) was treated with E. coli LPS (20 microng/kg/h for 180 min); group 2 (n = 6) was infused with a thrombin inhibitor and LPS was administered similarly to group 1; group 3 (n = 6) was pre-treated with a dual ET-1 receptors blocking agent (20 mg/kg i.v.), before endotoxic shock. In presence of the thrombin inhibitor, the LPS-dependent pulmonary hypertension was still present, also if it was less important, and the changes in C sub (L) and R sub (L) were similar to that observed in group 1. The dual block of ET-1 receptors, at contrary, completely abolished the pulmonary hypertension, the changes in C sub (L) and R sub (L), due to LPS infusion, but worsened the systemic hypotension [Per valutare il ruolo della trombina e il coinvolgimento dell'endotelina-1 (ET-1) nella regolazione del tono broncomotore e vascolare, abbiamo utilizzato 18 suini anestetizzati, ventilati meccanicamente, suddivisi in tre gruppi. Il gruppo 1 (n = 6) era trattato con LPS di E. coli (20 microng/kg/h i.v. per 180 minuti); il gruppo 2 (n = 6) veniva infuso con un inibitore della trombina e veniva trattato con LPS con le stesse modalita' del gruppo precedente; il gruppo 3 (n = 6) era pre-trattato con un bloccante non selettivo dei recettori ET-1 (20 mg/kg i.v.) prima dello shock endotossico. In presenza dell'inibitore della trombina l'ipertensione polmonare dipendente da LPS era ancora presente, anche se a un livello minore, e i cambiamenti della C inf (L) e R inf (L) erano simili a quelli osservati nel gruppo 1.
