isolation and characterization of an endogenous type c virus of rhesus monkeys.a type c retrovirus was isolated from a continuous cell line established from a spontaneous esophageal carcinoma of a rhesus monkey (macaca mulata) by prolonged cocultivation with canine cells. a dna transcript of the viral rna hybridized to a high level and kinetic analysis indicated the presence of multiple copies of the viral genome in rhesus monkey dna, showing that the virus is endogenous in this species. the rhesus monkey virus closely resembles, in several respects, an endogenous type c v ...197987013
leucocyte migration inhibition test as an index of immunological response to measles virus. iv. blood, spleen, lymph nodes and peritoneal exudate cell reaction.the migration inhibition test of leucocytes isolated both from the peripheral blood, spleen and lymph nodes as well as peritoneal exudate cells of guinea pigs, immunized with the various doses of measles virus was determined. for in vitro testing of cellular immunity to measles virus, viral antigens could be used in both infective and inactivated form.197987118
similarity of casein- and endotoxin-induced, myeloma- associated and aged sjl/j amyloid in various strains of mice.amyloidosis was induced in a number of strains of mice by repeated injections of casein and endotoxin. spontaneous amyloid was obtained from balb/c mice bearing a myeloma tumor (igg2a producing mopc 173 tumor) and from aged sjl/j mice. both the induced and spontaneous forms were similar in their size, immunological reactivity, peptide maps and in the susceptibility of histological sections to oxidizing agents with or without trypsin digestion. since case-induced murine amyloid resembles the noni ...197987374
