[Proliferation and differentiation of nerve cells of the human NN. supraopticus et paraventricularis transplanted to the brain of adult rats]. / Proliferatsiia i differentsirovka nervnykh kletok NN. supraopticus et paraventricularis cheloveka, transplantirovannykh v mozg vzrosloi krysy.

Human fetal hypothalamic neurosecretory cells (NSC) were studied after transplantation into the third ventricle of the adult rat brain. 3H-thymidine uptake data have shown that the time of origin and proliferation of NSC of grafted tissue and of supraoptic and paraventricular nuclei in normal embryogenesis was similar. Specific staining revealed that the start of neurosecretory function in grafted tissue corresponded to the date when NSC began functioning in normal ontogenesis.

Enzyme immunoassays of ovarian metastatic antigen 8 (OMA-8) in sera of patients with ovarian cancer have shown its elevation in 74.5% of samples. OMA-8 levels did not correlate with histology, differentiation, clinical stage of the tumour or the presence of ascites. Increased OMA-8 levels in sera of 70% of patients with stage I-II ovarian cancer suggest that it may be a marker of this disease.
