Axonal outgrowth, i.e. number of axons, determined by ocular evaluation after 48 hr in culture. The experiment was repeated three times except for the concentrations of 10 and 100 ng/ml on SCG, which were repeated twice. For ranking see Materials and Methods subheading Axonal outgrowth. nd, Not determined; n, number of animals.
