Treatment of splenic leukocytes from Cornell K strain male chickens (homozygous at the B15 locus of the major histocompatibility complex) with ovine corticotropin-releasing factor (oCRF), before their co-incubation with naive chicken adrenal cells, resulted in an increase in corticosterone production. Supernatants from the oCRF-treated splenic leukocytes caused a time-dependent increase in corticosterone production when incubated with chicken adrenal cells. Adding oCRF directly to chicken adrenal cells did not increase corticosterone production. Pretreatment of peripheral leukocytes with oCRF increased their activity in a concanavalin A mitogen assay. Thus, chicken leukocytes stimulated with corticotropin releasing factor appear to increase the production of an "adrenocorticotropin-like" substance (adrenocorticotropin-like because it increases corticosterone production by adrenal cells), and increased their cell-mediated immune activity.

The clinical response of schizophrenic patients to treatment with gamma-type endorphins was found to be associated with certain HLA class I antigens (Bw22, B15, B13). Moreover, pretreatment of lymphocytes from healthy donors with des-Tyr1-gamma-endorphin (DT gamma E) inhibits the complement-dependent cytotoxicity between alloantisera and those HLA antigens, of which the frequency was increased among schizophrenic patients, who respond well to the gamma-endorphin therapy. Also for the opiate antagonist, naloxon interactions with HLA class I antigens could be demonstrated. Using the inhibition assay with DT gamma E it was possible to detect a subtype of HLA-A2, which, until now, was only defined by cytotoxic T lymphocytes and biochemistry. These data suggest an interaction between the HLA class I antigens and the receptor(s) for DT gamma E and naloxon, which may support the hypothesis that HLA class I antigens play a role in many recognition processes. Their role in immunological recognition would then be only a specialized form of a more general function.

Whilst investigating 26 members of the same family, we discovered 5 cases of multiple endocrine neoplasia type II a. The present report demonstrates the diagnostic value of basal plasma thyrocalcitonin (TCT) assays, before and after stimulation with pentagastrin, and of plasma carcinoembryonic antigen (CEA) assays. Some of the clinical features encountered were novel--e.g. in one patient the phaeochromocytoma was revealed by a haemothorax with cardiovascular collapse--and others were peculiar; thus, in 4 cases the medullary thyroid carcinoma (MTC) was less than 2 cm in diameter and without lymph node or visceral metastases, even in patients aged 87, 59 and 56. More classically, MTC, always multifocal, was clinically silent, as were the two cases of phaeochromocytoma and hyperparathyroidism. Phaeochromocytomas were difficult to diagnose. Ultrasonic tomography did not prove very helpful and the disease was transmitted as an autosomal dominant trait. Finally, MTC secreted a variety of substances (TCT, CEA, beta-endorphin, somatostatin), and HLA A2-B15 antigens were found in 3 patients.
