Treatment of Pseudoaneurysm of Internal Maxillary Artery Resulting from Needle Injury.

Pseudoaneurysm of internal maxillary artery (IMA) after trauma is rare, and most cases reported are caused by maxilla-facial blunt trauma. Pseudoaneurysm is discontinuity in the vascular wall leading to an extravascular hematoma that freely communicates with the intravascular space producing pulsatile hematoma rapidly. A 44-years-old woman presented with a pulsatile swelling and pain in the left parotid region.

Cobalt chloride-induced apoptosis and extracellular signal-regulated protein kinase 1/2 activation in rat C6 glioma cells.

Brain ischemia brings about hypoxic insults. Hypoxia is one of the major pathological factors inducing neuronal injury and central nervous system infection. We studied the involvement of mitogen-activated protein (MAP) kinase in hypoxia-induced apoptosis using cobalt chloride in C6 glioma cells.
