为比较下腰痛非手术疗效,４１９例腰椎间盘突出症患者采用腰椎牵引（甲组１９５例）、激素硬膜外注射（乙组１９２例）及经皮穿刺椎间盘切吸术或胶原酶溶解术（丙组３２例）进行治疗和随访,采用改良Ｍａｃｎａｂ标准评定。结果：优良率甲组４９％,乙组６６％,丙组８４％,Ｐ＜０．０１;甲组疗效与病程相关,病程＜６个月疗效较好（Ｐ＜０．０５）;平均治疗次数有甲组＞乙组＞丙组的倾向。结论：单纯腰椎牵引对病程较短者疗效较好;病程较长,神经根刺激症状明显者加用激素硬膜外注射可提高疗效;经腰牵、激素硬膜外注射等非手术治疗无效者,如严格掌握适应证和操作技术,采用经皮穿刺椎间盘切吸术或胶原酶溶解术可取得很好疗效     

Analysis of orthograde fast axonal transport and nonaxonal transport along the optic pathway of albino rabbits during increased and decreased intraocular pressure

Orthograde fast axonal and nonaxonal transport through the optic disc was studied quantitatively and autoradiographically in albino rabbits during elevated (30 or 50 mmHg), normal (13–15 mmHg) and decreased (0–4 mmHg) intraocular pressure (IOP). In cases of intraocular hypertension up to 50 mmHg, autoradiographic findings of a disturbed orthograde fast axonal transport were seen in the optic disc within 3 hr. The blockage was relatively mild and uniform, and was distributed adjacent to the extension line of sclera. Despite this histological evidence of blockage, a quantitative analysis showed no statistically significant decrease in axonally transferred radioactivity within 3 hr. Decrease in the transferred material was evident at 6 hr, and the extent of decrease was mild (ca. 20% at the most prominent portion). In cases of moderate intraocular hypertension (30 mmHg) for 6 hr, a quantitative analysis showed no decrease in axonal transport. After 3–6 hr of intraocular hypotension (0–4 mmHg), papilledema did not develop and autoradiographically there was no accumulatjon of axonal components. Axonally transferred material remained quantitatively at the same level as in the control animals. Nonaxonal transport along the optic nerve was doubly enhanced in cases of intraocular hypertension up to 50 mmHg, and was reduced to one thrid at level of 0–4 mmHg. Filtration of intraocular fluid through the optic disc appears to be the largest component of the nonoxonal transport.     

Lumbar disc herniation in teenagers

Summary We report 48 patients operated on for lumbar disc herniation in the second decade of life (aged 13–20 years) in our Neurosurgical Division. To analyze the clinical and diagnostic features and surgical outcome of the disease in teenagers and to point out any differences from adults, we made a detailed study of over 900 juvenile cases and compared them with 11000 adult cases reported in the literature. Low-back pain proved to be less frequent among youngsters both as a first symptom and at diagnosis, while sensorimotor deficits have the same frequency in the two age groups. Herniation occurs more often at L4–L5 and is more frequently median among teenagers. The long-term surgical results in children and adolescents are better than in adults.     

Histochemical and ultrastructural observations on brown degeneration of human intervertebral disc

Thirty-eight fresh human intervertebral discs collected during anterior interbody fusion surgery were histochemically and ultrastructurally analyzed for pigments. Macroscopically, five stages of degeneration were classified according to the color, fibrosis, and fragility of the nucleus pulposus of the discs. In order to demonstrate lipofuscin granules, specimens were subjected to special staining procedures, including carbol fuchsin lipofuscin stain, the Schmorl's reaction, and autofluorescence. Lipofuscin granules were distributed from the inner layer of the annulus fibrosus to the nucleus pulposus. Such granules were numerous in cases of slight or severe degeneration, whereas fewer granules were found in cases of moderate degeneration. However, the stage of macroscopic degeneration of the intervertebral disc did not necessarily correlate with the incidence of lipofuscin granules. By ultrastructural observation, the morphological features of the components of the intervertebral disc and the ultrastructure of the lipofuscin granule were clarified. The ultrastructure of the "brown degeneration" disc exhibited markedly increased amorphous electron-dense bodies located among collagen fibrils in the matrix.
