Effect of a high-intensity static magnetic field on sciatic nerve regeneration in the rat.

The effect of a high-intensity static magnetic field on peripheral nerve regeneration is evaluated in rat sciatic nerve. Forty-four rats underwent sciatic nerve repair using polyethylene nerve guides. Postoperatively, the animals were exposed to a 1-tesla magnetic field for 12 hours per day for 4 weeks with appropriate controls. Our results demonstrate that a 1-tesla static magnetic field has no statistically significant effect on nerve regeneration as determined by myelinated axon counts and electrophysiologic studies. Also, the specific orientation of the sciatic nerve with respect to the magnetic field has no influence on axonal growth or nerve conduction. Periods of restraint of 12 hours per day for 4 weeks significantly inhibit weight gain but have no effect on peripheral nerve regeneration.

Intravenous cholangiography: optimum dosage and methodology.

Cholangiography was performed in 442 patients using four dosage regimens of Cholografin: (a) a single-dose, full-strength injection in 10 minutes (150 examinations), (b) two dilute (76 examinations) or very dilute single doses (71 examinations) infused in 30 minutes, and (c) one dilute double dose infused in 30 minutes (145 examinations). Results showed that the double-dose infusion gave maximum visualization, followed by the single-dose injection and the two single-dose infusions. With the double-dose method, both the reaction rate and the incidence of SGOT elevation were twice that seen with any single-dose method, making the single-dose injection the procedure of choice despite slightly lower opacification.

The challenge of continuing medical education.

Continuing education is an important responsibility in the practice of radiology. The response to the growing demand for additional and new educational opportunities includes specialty societies and their programs of scientific paper presentations and refresher courses, audiovisual aids and seminars. Lacking, however, is organization of efforts leading toward programmed instruction, permitting renewal and expansion of knowledge on an organized and continuing basis. The Intersociety Educational Committee is attempting to coordinate educational efforts. A unified and effective educational process would eliminate much duplication of effort and increase efficiency.
