  • Poly(ethylene terephthalate) (PET) has been etched by sputtering in the presence of argon gas and the resulting surface modifications investigated via weight loss, time of water permeation, half value period, scanning electron microscope(SEM) and color difference measurements. According to increasing sputter etching time, weight loss increased, the time of water permeation and half value period of the sputter etched PET fabrics decreased. Color depth of fabrics increased by increasing sputter etching time. We investigated the fabric surface modification by SEM. Many microcraters on the fabric surface formed by the sputter etching resulted in increase of surface area of the fabric and wettability.

  • Continuous epidural blockade has been used widely for providing anesthesia and analgesia. But many kinds of unusual complications have been reported such as: kinking, knotting, shearing, abnormal positions of catheter, etc. We experienced a case of malposition of the catheter which pass out the epidural space through the intervertebral foramen in a 33-year-old cancer patient. We confirmed it by epidurogram.
