Remarks on the mass balance for multi-compartmental models; a nonlinear compartmental model.

The article presents remarks on the paper "A Commentary on Fractionalization of Multi-Compartmental Models," by A. Dokoumetzidis and colleagues, focusing on the mass balance for multi-compartmental models, a form of nonlinear compartmental model. It mentions the preservation of the mass balance in the equations presented. It points out a printing error in a one equation. It recommends the presentation of another possible generalization of the system of equations treated in the article.
