Vasopressin-neurophysin (hNpI), oxytocin-neurophysin (hNpII) and blood osmolality were assayed before any treatment in basal conditions in 35 patients suffering from lung carcinoma (20 oat cell, 6 undifferentiated and 9 well-differentiated epidermoid cell carcinomas). Plasma vasopressin (antidiuretic hormone, ADH) was also assayed in 7 of the 20 patients suffering from oat cell carcinoma. We found a close correlation (r = 0.98) between plasma ADH and hNpI levels in the 7 patients. Further, hNpI was elevated in 13 out of the 20 oat cell carcinoma patients and in none of the epidermoid-cell carcinoma group; however, searching for an abnormality of ADH secretion as reflected by a detectable plasma hNpI level together with subnormal plasma osmolality revealed 2 additional positive results in the oat cell carcinoma group, and 2 out of the 6 in the undifferentiated-cell carcinoma group. hNpII was increased together with an increase in hNpI in 6 oat cell carcinoma patients; it was specifically increased without hNpI increment in 2 additional oat cell carcinoma patients and in 2 patients of the undifferentiated-cell carcinoma group (different from the 2 positive for the hNpI-osmolality ratio). hNpI and hNpII were normal in the majority of undifferentiated and all of the differentiated epidermoid-cell carcinoma group. Hence, our results show that simultaneous measurements of hNpI, hNpII, and blood osmolality could detect abnormalities in 17 out of 20 oat cell carcinoma patients, in 4 of the 9 undifferentiated-cell carcinoma patients, but in none of the differentiated epidermoid-cell carcinoma patients, suggesting that the neurophysin assay can be used for the early detection of oat cell- and possibly other neuroendocrine-derived carcinomas.

The hypothalamo-neurohypophyseal function has been tested in 9 normal individuals (age 22 - 50; 2 women and 7 men) in the course of a vasodilatator perfusion (sodium nitroprussiate) in standardized conditions. Vasopressin-neurophysin (hNPI), oxytocin-neurophysin (hNPII) and total immunoreactive neurophysins (IRN) have been assayed. Our preliminary results show a clear-cut increase of hNPI and IRN when the decrease of the mean blood-pressure exceeds 20 +/- 10% (15 - 33). There is only a weak, if any, increase of hNPII. There is a highly significant relationship (r : 0.90, p less than 0.01) between maximal increment of IRN and maximal increment of heart frequency suggesting a similar way of activation. Vasodilatator perfusion could be, in the future, a reliable test for hypothalamo-neuropituitary function although it's reproducibility has still to be deeper investigated.
