Effects of semi-refined carrageenan (food additive E407a) on cell membranes of leukocytes assessed in vivo and in vitro
Aim To assess the impact of semi-refined carrageenan (E407a) on hydrophobic regions of phosphololipid bilayer in cell membranes of leukocytes collected from rats orally administered this food additive and white blood cells incubated with E407a.Methods Fluorescent probes (ortho-hydroxy derivatives of 2,5-diaryl-1,3-oxazole) were used to estimate the...

A study of enterocyte membranes during activation of apoptotic processes in chronic carrageenan–induced gastroenterocolitis
Aim To investigate the lipid membranes of rat enterocytes in chronic carrageenan-induced gastroenterocolitis accompanied by the activation of apoptotic processes. Methods Steady-state fluorescence spectroscopy: a study by fluorescent probes-by ortho-hydroxy derivatives of 2,5-diaryl-1,3oxazole. Activity of apoptosis signal-regulating kinase 1 and p...
