Sphaeroides oblongus: cardiovascular and respiratory effects
Sanyal Bratati, BB Patra, BP Mukherjee, S Ganguli
A toxic principle (FT) isolated from Sphaeroides oblongus, a poisonous fish, showed dose-dependent (25-800 'g/kg) decreasein cardiac rate and blood pressure accompanied by respiratory depression including transient apnoeic phases in urethane-anaesthetized cat preparations. A peripheral mechanism of action comprising blockade of sympathetic (vasomotor) axonal conductiion, a transient myocardial depression and partial direct musculotropic effect is suggested to be responsible for the bradycardia, hypotension and respiratory depression.
