Extracellular signal-regulated kinase phosphorylation due to menadione-induced arylation mediates growth inhibition of pancreas cancer cells.

Background: Cytotoxicity of Vitamin K3 (VK3) is indicated to have the same mechanism with oxidative stress (H(2)O(2)). In the present study, we analyzed the differences and/or similarities in the cellular responses to oxidative stress and VK3 to clarify the mechanism of growth inhibition.

Methods: Cell viability was determined by a test method with 3-[4, 5-dimethyl-thiazol]-2, 5-dephenyl tetrazolium bromide (MTT).

Ileal perforation in a patient with high spinal cord injury: report of a case.

Assessing abdominal complications in patients who have previously suffered high spinal cord injury is very difficult because the resultant loss of sensory, motor, and reflux function of the abdominal wall can mask the typical signs of acute abdomen such as tenderness, muscle rigidity, and peritoneal rebound pain. We recently diagnosed a small intestinal perforation in a 77-year-old man with a C6-7 spinal cord injury sustained 14 years earlier. The patient was correctly diagnosed as having an acute abdominal condition, despite palsy of abdominal wall sensation.
