Microradiographicstudies in the sialogram of the submandibular gland of the dog in various conditions were carried out and the results are as follows.Techniqe of X-ray ;500u thick frozen sections of the submandibular gland were put on the films. The pictures were made by means of Softex(18 KV and 10mA).(1) The normal group:The contrast medium (40% Moljodol with lard added), which filled the Whartons duct and the branchs of the duct and arrived to the acini showed the small spotty sha- dows.An increase in the amount of the injected medium showed an in crease in density and enlarg- ment of the small spot shadows.(2) The group with acute inflammation:Ma- ny of the sialograms showed the dapple-like sha- dows at the gland portion.The microsialogram (M-gram) of these cases indicated granule-like or confluenced shadows of medium, which were for- med by leakage of the medium in the tissue of the surrounding of the ductules.(3) The group with destructive alteration: The sialogram showed the dapple-like shadows and lighter than normal shadows at the gland portion. The M-gram of those cases was like(2), but of these cases the medium at the gland was rarely found.(4) The group with chronic inflammation: The duct system of the group in the sialogram showed the marked dilatation and the shadows at the grand portion showed almost normal types.The M-gram of these cases presentad marked dila- tation of the ductules and gave scattered small granule-like shadows at the gland portion.(5) The group with ligation of the Whartons duct:The sialogram was characteristic of the dilatation of the duct system.The findings of the M-gram were also remarkable for the dilatation of the duct, and showed unevenly small spot or small granule-like shadows at the gland portion.
