Major R&D obstacles include inability to recover whole plants from cultured cells of many economic plants, ignorance of hormone mechanisms, and lack of suitable markers and general methods for ...producing haploids. Too many grant proposals ignore basic principles, lack concise goals, and are not funded. Regional workshops and small meetings could help.

A previous study indicated that the Comprehension subtest of the Wechsler Adult Intelligence Scale (WAIS) might be a sensitive instrument for evaluating mental status in schizophrenic patients. To ...test this hypothesis, 3 groups of subjects were given the WAIS Comprehension subtest repeatedly at brief intervals. The results indicate that for a given individual (normal control or stable chronic schizophrenic), scores do not increase even with 4 consecutive weeks of testing. In contrast, a group of schizophrenic patients tested shortly after readmission and again after being established on neuroleptic medication showed a marked improvement in scores which, somewhat surprisingly, were not correlated with changes in global ratings of disordered thinking by the treating psychiatrist. This standardized test may offer a convenient objective technique for quantifying some aspects of thinking in schizophrenic patients.

Steroid secretion was ...studied during acute carotid arterial constriction and subsequently after exogenous ACTH injection in anesthetized animals with a chronic indwelling adrenal venous catheter. Aldosterone secretion increased during carotid constriction in only four of nine experiments. In one animal, the increment in aldosterone output was associated with an increase in adrenal blood flow. In the other three experiments the increase in aldosterone output appeared to be secondary to an elevation in circulating ACTH as indicated by simultaneous increments in corticosterone and cortisol secretion. A striking increase in secretion of all three steroids occurred following the subsequent administration of 100 mU ACTH. No evidence was obtained to indicate that carotid constriction augments aldosterone output by activation of a central nervous mechanism except via ACTH release. Key Words: steroid secretion corticosterone secretion cortisol secretion ACTH release
