Aberrant thyroid gland demonstrated by computed tomography.

Computed tomography (CT) demonstrated high attenuation values consistent with thyroid gland in scans of a patient with tumors in the base of the tongue and anterior median neck. Radioiodine scintigraphy revealed positive uptake in the same areas. This is an indication that CT attenuation values may be useful in the diagnosis of aberrant thyroid gland.

Detection of IgG antibody to measles virus by radioimmunoassay technique.

A highly sensitive procedure of solid-phase radioimmunoassay (RIA) was developed for the detection of measles IgG antibody. HeLa cells persistently infected with measles virus were used as a solid-phase antigen. This technique was applied to the detection of measles IgG antibody in patients with subacute sclerosing panencephalitis (SSPE) and multiple sclerosis. Normal subjects having experienced natural measles or measles vaccination and patients with various neurological diseases of non-virus nature were also examined as control groups. Measles antibody was detected at high titers in both the sera and cerebrospinal fluid of SSPE patients. Moreover, RIA/HI ratios of SSPE patients were significantly higher than those of normal subjects, suggesting the presence in the formers of antibodies to nucleocapsids at high titers as well as to viral envelopes. On the other hand, no significant difference was found in both RIA and HI titers between the sera of multiple sclerosis and those of various neurological diseases.

Establishment of a T-cell line from human lymphosarcoma.

A leukemic T-cell line, designated as TALL-1, has been established in continuous culture from the bone marrow of a patient with a leukemic phase of T-cell lymphosarcoma. TALL-1 cells have T-cell properties and lack Epstein-Barr virus or its genome. The cells of TALL-1 line are considered to have originated from the donor's leukemic cells on the basis of their cytogenetic, morphological, and surface features.
