Complement-fixing antibodies in the sera of 534 lepromatous lepers under treatment with sulfones.

Serological behavior of lepromatous sera in relation to complement fixation tests for syphilis, Chagas' disease and brucellosis.

However in a study of 467 lepromatous lepers, Almeida, Lima & Carvalho (1955), found the quantitative complement fixation test of Wadsworth, Maltaner & Maltaner (1938), highly specific for syphilis, when cardiolipin was used as antigen. It was pointed out that the evaluation of the specificity of the reactions, in many cases, was plagued by uncertainties, since reliable information of clinical ...

Complement-fixing antibodies in cattle experimentally infected with Theileria annulata or vaccinated with tissue cultures

The relation of immunoglobulin class, pattern of anti-nuclear antibody, and complement-fixing antibodies to DNA in sera from patients with systemic lupus erythematosus.

Sera from 55 patients with systemic lupus erythematosus were studied to clarify the significance of the patterns of nuclear fluorescence observed. The sera in which the IgG fraction produced a peripheral pattern of nuclear fluorescence were found to contain complement-fixing antibodies to native DNA and to DNA-histone complexes. This correlation did not exist when complement-fixing activity was...

A Case Study of Cryptococal Meningitis

A Case of Cryptococcal meningitis was diagnosed in a 22 year old Pigeon -fancier from Mazandaran prm ince of Iran (close to the Caspian sea). The patient was treated with systemic 5-nuoc to,;in and amphotericin B together with intrathecal injection of ampho. B. Further investigations showed an abnormal reduction in the number ofT-lymphocytes, while humoral immunity was maintained in the normal ...

Differences in acute and convalescent-phase antibodies of cats infected with feline picornaviruses.

Complement fixation inhibiting and complement-fixing antibodies were demonstrated in sera from cats during the acute and convalescent stages, respectively, of feline picornavirus infections. Complement-fixing antibody activity was present in 19S and 7S globulins, whereas complement fixation inhibiting antibody activity was confined to the 7S globulins. Sera with complement-fixing antibody and s...
