Three newly designed bayonet clips (crankshaft clips) are presented. They were designed to occlude aneurysms with irregular necks by using the angle and shank portion of a bayonet clip (shank clipping). The new clips have shorter distal blades and longer shanks (proximal blades), and the angle portions are bent to an angle of smaller degree. These clips are(More)
We reported the correlation between the angiographical findings and parameters of the functional images of dynamic CT (FID-CT) in ten patients with cerebral ischemic disease. Six of these ten patients with an abnormal area on corrected mean transit time (CM) and time to peak (TP) had complete occlusion of intracerebral main arteries with poor collateral(More)
Chemokines are potent chemoattractants for immune and hematopoietic cells. In the central nervous system, chemokines play an important role in inflammatory responses through activation of infiltrating leukocytes and/or resident glial cells. We previously demonstrated that N-methyl-D-aspartate (NMDA)-evoked neuronal injury induced astrocytic production of(More)
An attachment device to fix a Sedan side-biting biopsy cannula to a stereotactic frame is described. The disadvantages of the biopsy cup forceps are resolved, and a relatively large amount of multiple specimens can be obtained along a single biopsy trajectory. This attachment device enables the side-biting cannula to follow a straight trajectory biopsy in(More)
