Plasminogen activators in developing peripheral nervous system, cellular origin and mitogenic effect.

Newborn rat dorsal root ganglia release two different plasminogen activators (PAs): the urokinase (UK) and the tissue (tPA) type. The former is secreted by neurons while the latter is secreted by Schwann cells. tPA release by Schwann cells is modulated by choleratoxin, a known mitogen for these cells. UK but not tPA stimulates in a dose-dependent fashion the proliferation of Schwann cells. This effect is observed in the absence of plasminogen, suggesting that the substrate for PAs in the developing nervous system is not plasminogen. Since UK is secreted by neurons, our data suggest a new mechanism for neuronal control of Schwann cell proliferation. [less ▲]

Fifty patients with moderate or severe endometriosis received 5 mg/day lynestrenol for 6 months prior to microsurgery. A significant regression of the ovarian and peritoneal implants was observed in 72% of the cases after progestative treatment, but the presence of residual epithelium in all cases made surgical resection necessary. After preoperative medical treatment and microsurgery, intrauterine (living births) pregnancy rates of 60 and 47% were obtained in cases of moderate and severe endometriosis, respectively. The following prognostic factors were found in this series: the degree of endometriosis, the concomitant male factors, the decrease of endometriotic lesions after treatment, and the unilaterality of ovarian endometriosis.

The authors present 50 cases of cervical spondylotic myelopathy treated by anterior or posterior approach. To assess the severity of the pre- and postoperative neurological symptoms, they define an original ten-point classification scale taking into account gait and urinary disturbance, ability to manipulate objects and pain. With C2-C7 laminectomy, 60% of the patients are improved, essentially for walk. A few cases only (14%) are upgraded for upper limbs function. The authors conclude that this surgical treatment should be applied only when there is a multi-level narrowed canal and predominant lower limbs deficits. The efficacy of the anterior approach depends on complete removal of osteophytes. In cases with complete osteophytectomy, this surgical treatment can improve both the upper and lower limbs function and 77.8% good results are obtained. In a few cases it may be necessary to use both approach successively. Discriminant analysis applied to 12 factors shows that pre-operative scores of upper and lower limbs and sagittal diameter of spinal canal are the most important factors for neurological prognosis.
