“…Our results indicate that known depolarizing agents (K', veratridine, and monensin), as well as others (some amiloride derivatives), whatever their mode of action on the membrane potential, stimulate the metabolism of IPS (Fig. 2 and Tables 1 and 2) (Guiramand et al, 1989). These observations are in agreement with those of other authors showing that in addition to K+, veratridine, and monensin, ouabain, scorpion toxins, pumiliotoxin B, batrachotoxin, and aconitine also increase accumulation of IPS in various experimental models (Kendall and Nahorski, 1984;Habermann and Laux, 1986;Gusovsky et al, 1986;Audigier et al, 1988;Gusovsky and Daly, 1988ab;Baird andNahorski, 1989, 1990; Benuck et al, 1989ab).…”
