As experiencias demonstram que a conducção nuclear tambem se processa nos systemas praticamente impolizaveis, (metal/sol. do mesmo metal), onde é bem determinada e caracteristica. O estudo destes systemas pode fornecer dados seguros para a analyse do phenomeno da polarização, assim como do electrotonus physico do nervo. Na proxima nota analizaremos o phenomeno quantitativamente e esboçaremos sua theoria. Desejamos deixar expresso os nossos agradecimentos aos Professores Miguel Osorio de Almeida e José Felippe, pela attenção com que acompanham nossos trabalhos, assim como pelas suggestões que nos foram feitas, e ao Professor Evandro Chagas o nos ter facilitado o uso do Electrocardiographo.

Surgical removal of large amounts of hepatic tissue in male albino rats results in a rapid and conspicuous raise in cellular nuclear volumes. Measurements were made exclusively in resting nuclei. This volume variation is transitory. Nuclear volumes return to the normal value withins 6 days of restoration. The higher value are abserved 48 hours after the hepatic removal, indicating probably that this effect is due to hydration of the nucei, as occurs in the cytoplasm. This hydration could be correlated to the mitotic activity of the renmant tissue since a peak of mitoses parallels the changes in the nuclear volumes.

This comment corrects the errors in the estimation process that appear in Martins (2001). The first error is in the parametric probit estimation, as the previously presented results do not maximize the log-likelihood function. In the global maximum more variables become significant. As for the semiparametric estimation method, the kernel function used in Martins (2001) can take on both positive and negative values, which implies that the participation probability estimates may be outside the interval [0,1]. We have solved the problem by applying local smoothing in the kernel estimation, as suggested by Klein and Spady (1993).
