Effects of 04 on cardiovascular system and respiratory system: 1 iv ricin 3.2mcg/kg is the critical dose to produce toxic reactions of heart, liver and kidney in anesthetized rabbits, and less than this dose has no obvious effect on cardiovascular system and respiratory system. When anesthetized cats are injected with 250-500 μ g/kg, blood pressure immediately rises, pulse, respiration or tidal volume increases. When the injection dose was increased to 30mg/kg, the blood pressure dropped to zero, the heart stopped beating during diastole, and tidal breathing occurred and he died. Electrocardiogram showed prolonged R-R interval, disappearance of P wave and inversion of T wave. 250-500 μ g/kg ricin iv can slightly antagonize the B receptor stimulant isoproterenol in anesthetized cats. The first injection of 25 mg/kg ricin can weaken all pharmacological effects of epinephrine, norepinephrine, acetylcholine, vasopressin and histamine. Ricin can also reduce the reflex of ricin and nicotine. Ricinine can also cause blood pressure drop and respiratory depression in experimental animals, which may be related to the cyano group contained in its molecule. Castor leaf decoction can increase the amplitude of normal isolated frog heart and frog heart poisoned by chloral hydrate, ergot extract, acetylcholine, atropine, quinine and potassium chloride. The decoction can lower blood pressure in dogs and dilate blood vessels in hind limbs of rats.
