{"product_id":"the-paraganglia-von-p-bock","title":"The Paraganglia","description":"\u003cp\u003eOur knowledge of chromaffin tissue has increased enormously since the last comprehensive treatise in this series was published in 1943, chiefly as a result of the development of new histological methods and technical improve­ ments. Less than 40 years have passed since the review by MAX WATZKA, and essentially only 25 years were required to accumulate an abundance of revolu­ tionizing findings: it was not until 1957 that the carotid body was first studied successfully with the electron microscope. In 1962 the technique of formalde­ hyde-induced fluorescence was introduced, yielding a view of adrenergic struc­ tures that was completely new and far better than that obtained with the chro­ maffin reaction. Immunohistochemistry made it possible to localize enzymes responsible for catecholamine synthesis and to detect peptide hormones. Autora­ diographic techniques were used at the level of the electron microscope, the method of chemical sympathectomy was introduced and still other technical improvements could be mentioned. I myself have been interested in chromaffin cells and sympathetic neurons since 1965, when I entered the Department of Histology, University of Vienna, as a medical student. Therefore I have not followed the developments mentioned above retrospectively, but have actually experienced them. Anyone who experi­ ences such a development comes to believe that he is well acquainted with the various results and interpretations and is thus capable of objectivity.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783642682100\"\u003e\u003ch3\u003e\u003c\/h3\u003e\u003c\/div\u003e","brand":"Libri","offers":[{"title":"Softcover - 9783642682100","offer_id":39432059519069,"sku":"9783642682100","price":106.99,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/6180aadf-f0ea-45d9-bfa2-725391f48216.jpg?v=1761716656","url":"https:\/\/shop.autorenwelt.de\/en\/products\/the-paraganglia-von-p-bock","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
