Histological Investigation Of The Rectal Sac In Bombyx Mori L., Gamze Turgay İzzetoğlu, Ayla Öber Jan 2011

Histological Investigation Of The Rectal Sac In Bombyx Mori L., Gamze Turgay İzzetoğlu, Ayla Öber

Turkish Journal of Zoology

The rectal sac (Rs) is formed by enlargement of the rectal portion of the hindgut in Bombyx mori. The Rs consists of epithelium, connective tissue, and many rectal pads (Rps). Rps have a cortex and medulla. In the medulla 2-5 pyramidal epithelial cells synthesize proteinic secretory material (Ps), and then this substance localizes within epithelial cells and connective tissue. It was thought that lipoid secretory material (Ls) was synthesized by epithelial cells in the midgut and was delivered to the Rs; however, Ls was localized in the epithelium of the Rs and in the periphery of Rps. Both secretions were …

United States Department of Agriculture Wildlife Services: Staff Publications

What are the birds worth--what is their actual dollar value to human society? To most of us in the ornithological community, birds are invaluable. But in these times we need more specific rationales to convince policy makers and business leaders to include bird conservation in land-use and development decisions. Over the past two decades, awareness of our dependence on a variety of ecosystem services (natural ecological processes that benefit human society) and of their importance and prevalence has progressed toward the goal of making conservation a mainstream value. Building strategies for the protection of ecosystem services into conservation and land-use …

Morphological And Ultrastructural Changes In Tissues Of Intermediate And Definitive Hosts Infected By Protostrongylidae, Abdurakhim Ergashevich Kuchboev, Eric P. Hoberg Jan 2011

Morphological And Ultrastructural Changes In Tissues Of Intermediate And Definitive Hosts Infected By Protostrongylidae, Abdurakhim Ergashevich Kuchboev, Eric P. Hoberg

Turkish Journal of Zoology

Cellular and subcellular mechanisms involved in tissue responses to larval and adult lungworms (Protostrongylidae) were respectively explored through experimental and natural infections in molluscan intermediate (Xeropicta candacharica) and ruminant definitive hosts (Ovis aries). Reaction to developing larval stages in the gastropod is manifested as cellular infiltration involving lymphocytes and macrophages into the infected tissue, which restricts damage and may result in destruction and elimination of parasites from the intermediate host. Variations in the patterns of localization for infective third-stage larvae in the foot tissue of the intermediate host are described. In the definitive host, evaluation of lung tissue by histology …
