The Relationship

The question of the relationship of the endocrine glands, and in particular the adrenal glands, to immunity has not yet been finally resolved: while some authors recognize only the indirect importance of the endocrine organs in the fight against infection, given the extremely extensive biological role of these organs in the life of the animal body, others are inclined to seek a more direct relationship, allowing their participation or in the production of antithelials, or in the neutralization of bacterial toxins.

Abstract Extensive efforts have been made to explore how the activities of multiple brain cells combine to alter physiology through imaging and cell-specific manipulation in different animal models. However, the temporal regulation of peripheral organs by the neuroendocrine factors released by the brain is poorly understood. We have established a suite of adaptable methodologies to interrogate in vivo the relationship of hypothalamic regulation with the secretory output of the pituitary gland, which has complex functional networks of multiple cell types intermingled with the vasculature. These allow imaging and optogenetic manipulation of cell activities in the pituitary gland in awake mouse models, in which both neuronal regulatory activity and hormonal output are preserved. These methodologies are now readily applicable for longitudinal studies of short-lived events (e.g., calcium signals controlling hormone exocytosis) and slowly evolving processes such as tissue remodeling in health and disease over a period of days to weeks.

The Relationship

Braier (1931) showed that hypophysectomised dogs on a complete diet excrete 24 per cent. less urinary creatinine than the controls, and 35 to 40 per cent. less when fasting. Schrire and Zwarenstein (1933, 1934) found that injection of anterior lobe extracts increased the urinary creatinine in rabbits.These results afford evidence of an endocrine relationship between the anterior lobe of the pituitary and urinary creatinine. In view of the well-established relationship between urinary creatinine and muscle creatine the present authors decided to investigate the relationship of the anterior lobe to muscle creatine. An effect on phosphocreatine of muscle was reported by Marenzi (1933), who obtained a decrease of 33 per cent, following removal of the anterior lobe of the pituitary. The effect of hypophysectomy and of injections of anterior lobe extracts on muscle creatine has not been previously investigated.

The Relationship

The study of the relationship of the psychical and the endocrine mechanisms is made more difficult by the fact that the body does not react by separate systems, but as a coherent interlocking piece of machinery. Not only does the mind react on the glands and vice versa, but each gland reacts on the others to some extent. If follows therefore that one syndrome can be produced by two or more glands or by the mind and one gland. An example of the first is the adiposity, sexual dystrophy and hirsutism which make adrenal and pituitary syndromes so confusing, and of the second the difficulty in differentiating anxiety states from thyroid disease.

Biologic Factors

The Mesozoic-Cenozoic coral Order Scleractinia has been suggested to have originated or evolved (1) by direct descent from the Paleozoic Order Rugosa or (2) by the development of a skeleton in members of one of the anemone groups that probably have existed throughout Phanerozoic time. In spite of much work on the subject, advocates of the direct descent hypothesis have failed to find convincing evidence of this relationship. Critical points are:(1) Rugosan septal insertion is serial; Scleractinian insertion is cyclic; no intermediate stages have been demonstrated. Apparent intermediates are Scleractinia having bilateral cyclic insertion or teratological Rugosa.(2) There is convincing evidence that the skeletons of many Rugosa were calcitic and none are known to be or to have been aragonitic. In contrast, the skeletons of all living Scleractinia are aragonitic and there is evidence that fossil Scleractinia were aragonitic also. The mineralogic difference is almost certainly due to intrinsic biologic factors.(3) No early Triassic corals of either group are known. This fact is not compelling (by itself) but is important in connection with points 1 and 2, because, given direct descent, both changes took place during this only stage in the history of the two groups in which there are no known corals.

Insight Into

Echinodermata is a phylum of marine invertebrates which has been extant since Cambrian time (c.a. 500 m.y. before the present). Modern examples of echinoderms include sea urchins, sea stars, and sea lilies (crinoids). The endoskeletons of echinoderms are composed of plates or ossicles (Fig. 1) which are with few exceptions, porous, single crystals of high-magnesian calcite. Despite their single crystal nature, fracture surfaces do not exhibit the near-perfect {10.4} cleavage characteristic of inorganic calcite. This paradoxical mix of biogenic and inorganic features has prompted much recent work on echinoderm skeletal crystallography. Furthermore, fossil echinoderm hard parts comprise a volumetrically significant portion of some marine limestones sequences. The ultrastructural and microchemical characterization of modern skeletal material should lend insight into: 1). The nature of the biogenic processes involved, for example, the relationship of Mg heterogeneity to morphological and structural features in modern echinoderm material, and 2). The nature of the diagenetic changes undergone by their ancient, fossilized counterparts. In this study, high resolution TEM (HRTEM), high voltage TEM (HVTEM), and STEM microanalysis are used to characterize tha ultrastructural and microchemical composition of skeletal elements of the modern crinoid Neocrinus blakei.
