Studies on vaccinia haemagglutinin: II. Some immunological properties

Studies on plague. II. Immunological properties of purified Pasteurella pestis toxin.

The role played by the toxin of Pasteurella pestis in immunity against plague has been to date largely conjecture. The isolation of a highly purified toxin from this organism (Ajl et al., 1955) offers the necessary specific agent for the investigation of this problem. The studies to be described in this report were undertaken with a threefold purpose. They included (a) an attempt to manufacture...

On some properties of Banach operators. II

Using the notion of a Banach operator, we have obtained a decompositional property of a Hilbert space, and the equality of two invertible bounded linear multiplicative operators on a normed algebra with identity. 1. Introduction. This paper is a continuation of our earlier work [7] on Banach operators. We recall that if X is a normed space and α : X → X is a mapping, then following [4], α is sa...

In vivo antiviral properties of biologically active compounds. II. Studies with influenza and vaccinia viruses.

The in vivo anti-influenza virus and antivaccinia virus activity of 156 biologically active compounds was determined. One of two criteria was used for evaluating activity against the influenza virus. The criteria were increase in survivor number and mean survival time, and reduction in virus-induced lung consolidation in treated, infected Swiss mice. Increase in survivor number and mean surviva...

Chemo-immunological Studies on Conjugated Carbohydrate-proteins Ii. Immunological Specificity of Synthetic Sugar-protein Antigens

The function of carbohydrates as determinative substances in bacterial specificity is well illustrated in the immunological differentiation of thespecific types of pneumococci and of Friedlander bacilli. Previous studies have demonstrated that the presence of type-specific polysaccharides in these encapsulated organisms determines the antigenic properties of the cell and the serological relatio...
