Segmented organisms have serially repeated structures [1] that become specialized in some segments [2]. We show here that the Drosophila corpora allata, prothoracic glands, and trachea have a homologous origin and can convert into each other. The tracheal epithelial tubes develop from ten trunk placodes [3, 4], and homologous ectodermal cells in the maxilla and labium form the corpora allata an...

The aim of this study was to detect the regional and mucosal distribution of endocrine cells that secrete gulcagon, somatostatin, Chyholecystokinin-8 (CCK-8), serotonin, secretin, substance P (SP) and histamine in the small and large intestine of New Zealand white rabbit (Oryctolagus cuniculus L.) using immunohistochemical peroxidase-antiperoxidase (PAP) method. It was found that most of the im...

Prof. L. Ya. Pine s, whose name became known far beyond the borders of USSR thanks to his outstanding work in field innervation endocrine glands, gives collection a generalization head. them by sector normal histological data on glands and number works employees that replenish this data. The contains preface Pines, 7 articles (L. Narovchatova, R. Maiman, I. Pis, M. Sheftel, B. Shapiro, Kurepin)...

hypothalamic-hypophyseal complex, the gonads, pancreatic islet cells, adrenal glands, thyroid glands, parathyroid glands, ultimobranchial glands and the endocrine cells of the gut. All these organs release hormones into the bloodstream, which act on target tissues by interacting with receptors on the surface of the cell (peptide hormones) or within the cytoplasm or nucleus of the cell (steroid ...

As it regulates important physical functions and general wellbeing, the hypophysis plays a major role in responding to increased demand for different hormones. In current review, we described anatomical histological structures of pituitary glands domestic animals. Unlike other glands, gland has two main parts; adenohypophysis (anterior lobe), which contains multiple populations endocrine cells ...

Endocrine system can be affected by various organic compounds. The review describes the effects of major industrial solvents on adrenal, thyroid and parathyroid glands in man and experimental animals. Further, their toxicity in pancreas, pituitary, testis and ovary has also been discussed. An attempt has been made to offer a historical and general information on solvent toxicity in endocrine gl...

We report a case of non-Hodgkin's lymphoma(NHL) with simultaneous involvement of both thyroid and bilateral adrenal glands. Literature review on a computerized search showed that this is an extremely rare condition. The final diagnosis of diffuse large B cell lymphoma was confirmed by biopsies of thyroid gland, enlarged cervical lymph node, and adrenal gland. The significant endocrine dysfuncti...
