Table 1: Liposomal β-Glucan: particle size, encapsulation efficiency and polydispersity index: Particle size, polydispersity index (P.I.) and encapsulation efficiency of β-Glucan into liposomes. Particle size and polydispersity index (P.I.) of liposomes were determined by photon correlation spectroscopy with the use of Submicron Particle Sizer. All liposomes preparations were analyzed and Gaussian distributions were recorded. P.I., gives the measurement of homogeneity of dispersion, ranging from 0.0 (homogenous) to 1.0 (heterogeneous). Encapsulation efficiency was determined as the percentage of β -Glucan incorporated into liposomes relative to initial total amount of drug in solution. Results are given as means ± S.E.M. of three separated experiments in triplicate. ****P<0.0001.
