A FURTHER CONSIDERATION OF COMPLEMENT FIXATION IN TUBERCULOSIS

Studies on Complement Fixation in Tuberculosis. Iii

The prolonged extraction of the tubercle bacillus with boiling ethyl alcohol, followed by one or more reprecipitations by chilling the hot alcoholic solution, easily yields a preparation very active as antigen in the complement fixation reaction. This preparation gives a precipitation reaction with high dilution of the normal blood serum of a number of species. The precipitation reaction presen...

A Further Consideration O F Ewing’s Sarcoma

Since Ewing’s first report of a previously unrecognized tumor of bone derived from endothelial elements (1)’ there have been numerous reports of tumors which have conformed with his endothelial myeloma, and others which have sought to deny the existence of such a tumor. Among these was an article by the present writer (2) agreeing almost entirely with Ewing’s conclusions. Kolodny (3) believed t...

Complement Fixation in Diseased Tissues

An immunohistologic complement fixation test has been used in an effort to detect immune complexes in sections of kidney from rats injected with rabbit anti-rat kidney serum and in sections of biopsied kidneys from four humans with membranous glomerulonephritis. Sections of the rat and human kidneys were treated with fluorescein-conjugated anti-rabbit globulin or antihuman globulin respectively...
