On the age-associated presence of immunoglobulin and complement in the renal glomeruli of mice.

Immunofluorescence studies revealed the age-associated presence of mouse IgG, with or without beta1 C in renal glomeruli of various strains of laboratory mice. These were classified into two types: (1) IgG demonstrated without beta1 C and the fluorescence of which was easily decreased by prewashing with PBS. (2) IgG demonstrated almost always with beta1 C and the fluorescence of which remained unchanged by prewashing with PBS. The deposition of immunoglobulin seems to be closely connected with the immune state of animals including the phagocytic function of the mesangium.

The application of immunofluorescence to the study of renal disease. I. Influences of various conditions of specimens and conjugates on the fluorescent patterns of kidney.

Some basic problems in immunofluorescence were reexamined, limiting the object to kidneys. As to thickness of sections, 4 mum was demonstrated to be the most reasonable also to kidney specimens. Treatment of PBS for a short time before staining was recommended not only for cleanup effect but also for the possibility to disclose covered antigenic determinants. It was also established that fluorescent antibody with adequate F/P molar ratio, as well as with strict specificity, should be used, in order to prevent "false positives".

Antibacterial sesquiterpene aryl esters from Armillaria mellea.

Investigation of the mycelial extract of Armillaria mellea led to the isolation of the known melleolide (2a) and two new sesquiterpene aryl eters, 4-O-methylmelleolide (2b) and judeol (1c). Their structures were deduced from spectral data and that of (2b) confirmed by X-ray analysis. The new esters (1c) and (2b) showed strong antibacterial activity against gram-positive bacteria.
