Spinal cord regeneration: new experimental approach.

An experimental study was conducted to enhance regeneration in the spinal cord. Twenty Swiss albino rats were used, of which 8 were controls, and hemicordotomy was performed at mid-thoracic level. In 12 rats a segment of peripheral nerve (sciatic) autograft was taken, minced and implanted in the hemicordotomy site. All the rats were sacrificed at 4-12 weeks. Fixation was carried out by intracardiac perfusion of fixative. Light microscopy was used to study the hemicordotomy site. Two observations were made; first, regeneration of the cord was greatly enhanced, and second, the spinal cord caudal to the hemicordotomy did not disintegrate in the grafted cords.

CT values in orbital hydatid cyst.

The CT values of 15 cases of orbital hydatid cyst operated upon by the author were reviewed. It was found that hydatid cyst of the orbit has high CT value, contrary to the low CT value of nonorbital hydatid. This discrepancy was confirmed by an experiment using human skull and two balls simulating hydatid cyst. One ball was put in the orbit and the other in the cranial cavity. When the skull was CT scanned it was found that the orbital ball CT value was about five times higher than the cranial ball, in spite of the fact that both balls had the same content. It was concluded that the orbital bony pyramid is the cause of this high CT value in orbital hydatid. Hence it is recommended that an orbital lesion with a high CT value can be a hydatid cyst.
