salivary gland inflammation ( J:153355 )
• sialadenitis is observed in both diabetic and non-diabetic mice at 6 months of age; average number of lesions observed is similar to number found in NOD mice
insulitis ( J:153355 )
• diabetic animals develop insulitis, however, lymphocytic infiltration is less than in diabetic NOD controls
decreased susceptibility to autoimmune diabetes ( J:153355 )
• hyperglycemia in females occurs at a lower percentage and later incidence than NOD controls
