[Anti-hypoxia and anti-glucose deficiency effects of PQS on guinea pig papillary muscle in low frequency electrical stimulation].

Panax quinquefolium saponin (PQS) increases the contractibility of papillary muscle of guinea pigs during electrical stimulation with frequency of 1/8-1/64Hz (P < 0.05). In Krebs-Henseleit solution purged with gas containing 95% N2 and 5% CO2 regardless of containing glucose or not, PQS (0.3mg/kg) has the effect of anti-hypoxia and anti-glucose deficiency (P < 0.05, P < 0.01) in the electrical stimulation with frequency of 1/8-1/64Hz.
