The purpose of this study was to observe microscopic change of salivary gland tissue,
which is a cause of xerostomia in diabetic condition , for this target, the author injected
streptozotocin 0.1§¢/100 gm b.w. on the rat, Sprague Dawley, to induce diabetes, and
then observed microscopic changes in parotid gland tissue using light microscopy and
electron microscopy.
The results were as follows :
1. carotid gland tissue of the diabetic rat was atrophied or degenerated in lapse of
experimental time, but began to repair from 14 days after diabetic induction.
2. In the basal lamina of the vessel of parotid gland tissue in the diabetic rat, lamina
lucida was discontinued and lamina densa was increased in thickness, but the number of
capillary was gradually increased and dilated.
3. In acinic and intercalated ductal cells of parotid gland in the diabetic rat, changes
of mitochondria, RER, secretory granule, free ribosome were prominent.
In conclusion, the present study demonstrated that degenerative changes of the parotid
gland tissue were due to not completely thickening of the basal lamina of vessels, but
many other causal factors, because thickening of the basal lamina of vessels was not
related with degenerative changes.
