This study investigates the action of the central administration of the lectins isolated from Canavalia brasiliensis seeds (ConBr) and from Canavalia ensiformes seeds, (Concanavalin A, ConA) in the forced swimming test (FST) in mice. ConBr (1-10 micro g/site, i.c.v.), but not ConA, produced a decrease in the immobility time in the FST (observed at the time(More)
Overproduction of nitric oxide and activation of soluble guanylate cyclase (sGC) are important in sepsis-induced hypotension and hyporesponsiveness to vasoconstrictors. A time course of the expression and activity of sGC in a sepsis model [cecal ligation and puncture (CLP)] was evaluated in rats. Soluble GC alpha-1 and beta-1 subunit mRNA levels increased(More)
BACKGROUND AND PURPOSE There is increasing evidence that potassium channels are involved in the cardiovascular dysfunction of sepsis. This evidence was obtained after the systemic inflammation, cardiovascular dysfunction and organ damage had developed. Here we have studied the consequences of early interference with potassium channels on development of(More)
