Investigations on the presence of antibodies to papova viruses in patients with different forms of cancer and in other categories of patients or apparently healthy subjects. Note I. Neutralizing antibodies to SV-40 in the cerebrospinal fluid of patients with brain tumors and chronic neurological diseases.

Neutralizing antibodies to SV-40 were detected in cerebrospinal fluid samples from 16 out of 43 patients with brain tumors and in 6 out of 20 patients with different nonmalignant chronic neurological diseases. The patients' age excluded the correlation with a vaccine-associated or occupational contact with SV-40. The results ascertain the occurrence of SV-40 or of an antigenically related virus in the population of Romania.

Hormonal evidence for the dissemination through the cerebrospinal fluid, of secreting cells from invasive pituitary adenomas.

In 13 patients with invasive pituitary adenomas submitted to pituitary surgery (5 HGH-secreting adenomas, 6 prolactin-secreting adenomas, 2 non-secreting adenomas), the concentrations of HGH and prolactin (PRL) constantly decreased after operation both in the cerebrospinal fluid (CSF) and serum, and the CSF/serum ratio remained under one, with few exceptions. These last cases (2 with acromegaly, 2 with invasive prolactinomas), showed an increase of HGH or PRL concentrations in CSF when serum levels decreased; the CSF/serum ratio rose above one within 2 weeks post surgery in 2 patients, and within 2 years post surgery in another two. The circulation of CSF was not obstructed. This indicated the appearance of a new, extrapituitary source for secreting HGH or PRL directly into the CSF, a source which most probably developed through the dissemination, via CSF, of secreting cells from malignant pituitary adenomas.
