Median lethal dose

In toxicology, the median lethal dose, LD50, LC50 or LCt50 is a toxic unit that measures the lethal dose of a given substance. The value of LD50 for a substance is the dose required to kill half the m

…P, which triggers inflammation and pain. Studies on the effects of the venom in dogs have shown low lethal doses to be around 0.2 mg/kg (SC). The median lethal dose for females is 0.63 mg / kg (95% confidence interval [0.54-0.71], for females with egg sacs the LD50 is 0.61 mg / kg [0.56-0.73]. For males the LD50…
