Anticatalase Activity of Sulfanilamide and Related Compounds. I. Effect of Ultraviolet Irradiation

Autor: Edna R. Main, Lawrance E. Shinn, Ralph R. Mellon

Publikováno v: Experimental Biology and Medicine. 39:272-276

ConclusionsThe ability of sulfanilamide and structurally related compounds to develop color on ultraviolet irradiation appears to be dependent on the presence or absence of substituents in the p-amino and sulfamido groups. A study of the anticatalase

Anti-Catalase Activity of Sulfanilamide and Related Compounds. VI. Further Studies on Sulfonhydroxamides

Autor: Lawrance E. Shinn, Ralph R. Mellon, Edna R. Main

Publikováno v: Experimental Biology and Medicine. 44:596-600

SummaryP-Caproylaminobenzenesulfonhydroxamide produces bacteriostasis of pneumococci in blood without the lag characteristic of sulfanilamide. The activity is only about one-eighth of the corresponding bacteriostatic power in broth. That the immediat

Immunologic Disparities of Spore and Vegetative Stages of B. Subtilis

Autor: Ralph R. Mellon, Lillian M. Anderson

Publikováno v: The Journal of Immunology. 4:203-208

Résumé A rabbit immunized by a culture of killed B. subtilis spores develops almost an equal amount of agglutinins for both spores and bacilli, unless the disorganized remnants of the latter are removed from the antigen. A rabbit immunized with a c

On the Nature of the 'Cohesive Factor' in Spontaneous Agglutination of Bacteria

Autor: Ralph R. Mellon, W. S. Hastings, C. Anastasia

Publikováno v: The Journal of Immunology. 9:365-381

Introduction. This study purports to make inquiry into the physico-chemical nature and methods of combating the marked cohesion exhibited by many bacteria. As the studies of Northrup and DeKruif (1) have shown, cohesion plays an important part in the

Chemotherapy of Tuberculosis and the Mode of Action of the Sulfonamide Compounds

Autor: Ralph R. Mellon

Publikováno v: Diseases of the Chest. 8:166-172

In one of the sulfones is to be found the first chemotherapeutic agent against tuberculosis that has sufficient promise experimentally to justify a thorough-going trial clinically. As regards the difficult problem concerning the mode of action of the

Anticatalase Activity of Sulfanilamide and Related Compounds. III. Oxygen Tension and Bacteriostasis in Pneumococcal Cultures

Autor: Lawrance E. Shinn, Ralph R. Mellon, Edna R. Main

Publikováno v: Experimental Biology and Medicine. 40:640-645

Summary1. Reduction of the percentage of oxygen in the superambient air of broth cultures of the Type I pneumococcus greatly reduced or prevented bacteriostasis by sulfanilamide.2. When the oxygen concentration was reduced to 0.04% an actual stimulus

New Studies on the Filtrability of Pure Cultures of the Tubercle Group of Micro-Organisms

Autor: L. W. Fisher, Ralph R. Mellon

Publikováno v: Journal of Infectious Diseases. 51:117-128

The experiments to be reported here have been designed to overcome the last remaining obstacles to the acceptance of the view that the acidfast group of bacteria possess a filtrable phase in their life history. The matter is stated in this way becaus
