Biochemical approach to bovine leukemia.

Many bovine leukemic lymphocytes produce virus particles when kept in survival cultures in Eagle's Minimum Essential Medium supplemented with 20 percent of inactivated fetal calf serum. Virus particles equilibrate at a density of 1.16 g/ml in sucrose gradients and at a density of 1.12 g/ml in metrizamide gradients. Simultaneous detection tests show that a high molecular weight RNA-reverse transcriptase complex exists in these viruses. Hybridizations between total RNA from bovine leukemic lymphocytes and C-DNA prepared in various known RNA oncogenic viruses show that the virus associated with bovine leukosis is unrelated to RLV, SSV-1, MSV-Ki, FSV-Ga and FLV-Ri.

The chemical composition of idiopathic nonarteriosclerotic cerebral calcifications.

Calculi from a case of cerebral idiopathic nonarteriosclerotic calcification (Fahr's disease) were examined. The stone consists of hydroxyapatite and possesses a typical structure: the calcification process seems to be initiated by the formation of small round bodies that are cemented to each other to form the final stone. Calcified vessels are also present, but seem to be a secondary effect. From a comparison with other calcifications, it is concluded that no pathologic significance should be attached to the relatively high levels of trace metals such as zinc, iron, copper, magnesium, lead, and others, with the possible exception of manganese. The organic matrix of the stone contains large quantities of protein. On hydrolysis of this fraction, an important unidentified ninhydrin-positive peak was found. No mucopolysaccharides were found.
