Bioluminescent Study of the Distribution of High-Molecular-Weight Protein Fraction of Cellex Daily Preparation in the Brain after Intranasal Administation.

Permeability of the blood-brain barrier for protein fractions 50-100 kDa (PF) of Cellex Daily preparation labeled with fluorescent tracer FITC and non-conjugated FITC were compared after intranasal administration of the preparations to healthy rats. Fluorimetrical analysis of the serum and cerebrospinal fluid samples showed that Cellex Daily PF-FITC administered intranasally penetrated into the blood and cerebrospinal fluid with maximum accumulation in 2 h after administration and persists in the circulation for 24 h probably due to binding with plasma proteins. The differences in the kinetic profile of PF-FITC and free FITC indirectly suggest that the major part of the preparation is not degraded within 24 h and FITC is probably not cleaved from the protein components of the preparation.

[Immunomorphologic comparisons in glomerulonephritis].

Immunomorphological data in membraneous, mesangioproliferative, proliferative and fibroplastic types of glomerulonephritis revealed that the concentration of IgG was reduced in membraneous, the IgG and IgA in proliferative glomerulonephritis. T- B-suppression was weakened. T-immunodeficiency and increase of blood serum IgM was seen in all types of glomerulonephritis.
