Intranodal palisaded myofibroblastoma (IPM), also known as "intranodal hemorrhagic spindle cell tumor with amianthoid fibers," is a rare benign mesenchymal tumor originating from smooth muscle cells and myofibroblasts, often with the presence of amianthoid fibers. Usually IPM affects inguinal lymph nodes, but three cases have been described in the submandibular and cervical lymph nodes. We repo...

To clarify the mechanisms underlying the submandibular gland atrophies associated with ptyalolithiasis, morphological changes were examined in the rat submandibular gland following either surgical intervention of the duct or functional blockade at substance P receptors (SPRs). Progressive acinar atrophy was observed after duct ligation or avulsion of periductal tissues. This suggested that dama...

  The effects of gentamicin, lithium and combination of these drugs on ultrastructural morphology of rat submandibular glands were studied. Daily intraperitoneal injection of 40 mg/kg of gentamicin which causes chronic salivary gland toxicity, led to a marked decrease in gland's dry weight and total protein concentration but did not affect DNA content. Electron micrograph (EM) of submandibular ...

Sialolithiasis accounts for the most common etiology of salivary gland obstruction which leads to recurrent painful swelling of the involved gland which often exacerbates while eating. Stones may be encountered in any of the salivary glands but most frequently in the submandibular gland and its duct. Simultaneous sialolithiasis in more than one salivary gland is rare, occurring in fewer than 3%...

On physical examination, the right submandibular gland was diffusely enlarged and adherent. Also, seropurulen...

Calorie restriction reduces mammary mitogenesis and tumorigenesis. To test whether epidermal growth factor (EOF) levels are influenced by calorie intake, 72 four-week-old C3H/HeOu mice were separated into two groups and either fed ad libitum (group AL) or calorie-restricted at a mean 19% (group CR). Three mice from each group were evaluated when 6, 8,10, and 12 weeks old for submandibular gland...
