Abstract
Summary In the scrotal skin of the boar, the histochemistry of complex carbohydrates has been studied by means of a series of selected methods of light microscopy. The epidermis of the scrotal skin was found to contain neutral and acidic complex carbohydrates with different saccharide residues. The secretory epithelial cells and secretory substances of the saccular apocrine sweat glands contained sulfated, other acidic and neutral complex carbohydrates, whereas the secretory epithelial cells and secretory substances of the tubular apocrine sweat glands involved largely neutral complex carbohydrates. The two types of complex carbohydrates from the both glands were shown to contain commonly substantial amounts of various saccharide residues but were devoid of notable amounts of sialic acid residues. In addition, complex carbohydrates in the smooth muscle cells were reacted for relatively small amounts of saccharide residues. From the present results, the histophysiological significanses of complex carbohydrates in the particular histologic structures of the scrotum have been discussed with special reference to the functions of the skin in the boar.
