Keywords: α-gustducin DiI neuronal tracer enteric nervous system immunohistochemistry autonomic nervous system α-transducin morphometric analysis gastrointestinal tract mucosa-associated lymphoid tissue (MALT) Broiler Pectoralis major muscle parietal cells, enteroendocrine cells Fish oxyntopeptic and enteroendorcine cells

The researches concern the following topics: 1) Studies of cutaneous pathologies of the dog, by means of the use of the analysis of computerized image. 2) Morphologic studies in the gastrointestinal tract in the weaning pig after administration of alternative additives to the promoter of increase. 3) Immunocytochemical studies on the enteric nervous system in sheep with various genetic susceptibility regarding the scrapie in healthy and in naturally and experimentally infected subjects. 4) The morphology and the neurochemistry of descending and ascending myenteric plexus neurons of sheep ileum. 5) Immunohistochemical study of the presence of the α-transducin and α-gustducin immunoreactive cells and their enteroendocrine profile in the of human, swine, chicken and some fish species of commercial interest gastrointestinal tract: these α-subunit protein were also investigated in the testis and in the boar sperm.  6) Localization in pig skeletal muscle of proteins regulating intracellular lipid storage and mobilization. The presence of Perilipin 2 was related to the histochemical and immunohistochemical characteristic of muscle fibers. 7) The distribution, organization and innervation of gastric mucosa associated lymphoid tissue has been studied in conventional pigs by means of histological, immunohistochemical and DiI tracers methods. 8) Morphological and molecular-genetic characterization of an experimental model of  non-aganglionic congenital megacolon in the rabbit. 9) Histological and morphometrical study of the broiler Pectoralis major muscle skeletal fibers. 10) Study of the morphological characteristics of the gastrointestinal tract of fish of commercial interest: morphometric evaluations of oxyntopeptic and enteroendocrine cells.

Techniques of histochemistry, immunohistochemistry on whole mount preparations and organotypic culture, retrograde or ortograde transport were utilized for the researches.
