Ueber den Nachweis des Mucins in Geweben mittelst der Färbemethode

Morphological characterization of the glandular system in the salamander Plethodon shermani (Caudata, Plethodontidae)

“…Mixed glands ("Drüsen des dritten Typs" = "glands of the third type" as defined by Nicoglu, 1893), in which two-secretion glands are packed in one compartment, are not restricted to P. shermani but have long been known in the skin of amphibians (Hoyer, 1890;Nicoglu, 1893;Dawson, 1920;Delfino et al, 1986). Recent characterization of the skin in Plethodon cinereus by Sever and Siegel (2015) showed the presence of a third gland (described as a mixed gland) in addition to the typical granular and mucous glands.…”

Metachromasy: An Experimental and Theoretical Reevaluation

“…He recommended certain dyes because these stained "die granulierten Zellen metachromatisch, that is to say in a shade deviating from the color of the dye employed." "Chromoleptic substance," although peculiar to Adamkiewicz (1884 a, b;1885 a, b;1890), was the first generic term for substances which stain metachromatically. Paneth (1888) was the first to use the expression "metachromasie" and to carefully define it as a separate and distinct phenomenon (see Mayer, 1920, p. 73).…”

“…The proponents of a physical concept of staining led by Fischer (1899) insisted on the presence of more than one dye. Studies were burdened with this question for many years (Ball and Jackson, 1953;Bouma, 1883;Fischer, 1899;Griesbach, 1888;Hoyer, 1890;Kramer and Windrum, 1955;Lehner, 1924;Mann, 1902;Mayer, 1896;Paneth, 1888;Schaffer, 1888;Singer, Weiss, and Dempsey, 1951).…”

“…), myelin (Adamkiewicz, 1882(Adamkiewicz, , 1884Treitel, 1876; Car], 1877; etc. ), and nervenk5rperchen (Adamkiewicz, 1885 a, b;1890;etc. ) stained in a different color from that of the staining solution.…”

Histochemical Identification of Salivary Mucins

“…in the intestinal glands by Hoyer (1890), as described in his excellent work. This author noticed that while the salivary mucous alveoli showed a reddishpink metachromasia, the nuclei and the surrounding structures and the intestinal goblet cells were colored blue (orthochromatic).…”
