Spondylolisthesis has been become of considerable causative disease for low back pain in orthopedic field recently. Twenty-seven patients with spondylolisthesis, who were taken operation during a 7-year period from Jan. 1978 to Dec. 1984 at Department of Orthopedic Surgery of Presbyterian Medical Center, were studied and analized on clinical and radiological aspects and the results of obtained were as follows: 1. The averake age was 41.7 years with a range of 20 to 63 years, and the incidence was more common in female than male in all types. 2. By Wiltse's classification, isthmic type was most common and 19 patients were included and level of spondylolisthesis was common at fourth lumbar vertebra in degenerative type and fifth lumbar vertebra in isthmic type. 3. By Meyerding's grading, 14 patients (52%) were Grade 1, which was most common and the slipping measured by Taillard's method was most common with a range 10% to 19%, which included 13 patients (48%) and average slipping was 21.4%. 4. Meschan's angle was ranged from 5° to 19° with an average of 13.3°. 5. Myelogram was done in 13 patients and 9 of them showed positive findings. 6. Spina bifida was most common developmental abnormal finding and 11 patients (41%) were included. 7. Posterolateral fusion was done in 24 patients and anterior interbody fusion was done in 3 patients. 8. 24 patients who had taken posterolateral fusion were permitted to ambulate early at 2 weeks with Norton-Brown back brace. 9. After over a year follow-up, 23(85%) of 27 patients had satisfactory result. 10. After follow-up, 21(88%) of 24 patients who had taken posterolateral fusion had successful fusion.

Many difficult problems are encountered in the treatrnent of infected nonunion of long bone. To solve these difficult fractures, authors adopted an active approach-thorough debridement of the infected and necrotic soft tissue and bone, rigid internal fixation with autogenous cancellous bone graft and opening of the wound to ensure continuous drainage until union of the fracture. Authors treated 28 cases of infected nonunions with this method from Mar. 1980 to Feb. 1989, and the results are as follows ;1. Femur(54%) and tibia(43%) were most frequently involved sites. 2. Most of the cases(86%) were treated by rigid internal fixation and cancellous bone graft. 3. In most cases(64%), infection was controlled spontaneously by the time of bony union, but in 5 cases which showed persistent drainage, implant removal controlled the problem, and residual soft tissue and bony defect were solved by Papineau's technique or musculocutaneous flap. 4. Revision was required in 5 cases(18%) because of insercure fixation. 5. Union could be obtained in average 4.8 months, and infection could be controlled in all except 1 case.

The cellular alteration following the electric welding light on the rabbit corneal epithelial cells were studied in several conditions wearing various corneal contact lenses on the corneal surface exposed to the light for 5 minutes at 50 cm in each. The enucleated rabbit eyes 5 hours following the application of electric welding light were histopathologically investigated on the cellular structures of the cornea. The result were as follows: 1. The cellular alterations in a group of soft contact lens wearing consisted of multiple vacuole enlargement, separation of interdigitation and Desmosome, intracellular edema, and loss of organelles in superficial and wing cells layer. Loss of microvilli of the corneal superficial cells were observed. 2. Loss of cytoplasmic microorganelles and microvilli intercellular edema in superficial cell layer, and slight vacuoles enlargement in wing cells layer were demonstrated in a group of the direct light exposure group without contact lenses. 3. Loss of microvilli and intercellular edema with separation of interdigitation in superficial cell layer but no specific changes in wing cells layer were exhibited in a group of hard contact lens wearing. 4. The most destructive features of the corneal epithelial cells were observed in a group of soft contact lens wearing, and it was suggested that the doubtful effects of protection on the corneal superficial tissue in the case of soft contact lens wearing were noteworthy.

The CD8(+)CD28(+) T cells have known to mediate major histocompatibility complex class I-restricted cytolysis and to secret an HIV-1 inhibitory factor. As HIV infection lead to dramatic changes within the cellular immune system, the cellular cytotoxicities decrease in the duration of the HIV infection. To determine the importance of the cellular cytotoxicities in long-term nonprogression, we tried to compare CD28 expression on total T, CD4(+) T, and CD8(+) T cells as one of methods for cellular cytotoxicity measurements between long-term nonprogressor and normal person or between long-term nonprogressor and rapid progressor. The median percentages and counts of CD4(+) T cells of the norrnal, the long-term nonprogressor, and the rapid progressor groups were 39.9 and 0.96 * 10(9) cells/L, 24.6 and 0.58 * 10(9) cells/L, 9.9 and 0.15 * 10 cells/L, respectively. As a result of comparison of the cells having CD28 surface molecules on CD8(+) T cells in the long-term nonprogressor and the rapid progressor group, they showed over 5 times lower than that in the normal group. Especially, the long-term nonprogressor regarded to the healthy HIV-infected patient showed much lower CD28 expression on total T, CD4(+) T, and CD8(+) T cells than those of the normal person. The proportions of CD4'CD28 T and CD3CD28 T cell subsets showed the significant difference between the LTNP and the RP group. In conclusion, although HIV-infected patients were LTNPs having the steady CD4(+) T cell counts and no clinical symptoms, we suggested that HIV led to abnormality within the lymphocyte subsets such as the altered expression of CD28 molecules on various T cell subsets and this result would cause deficiency of host immune function and failure of control of HIV replication by anergy in T cell subsets.

Spinal cord compression is fatal condition to oncologic patients. Metastatic spinal cord compression from ovarian cancer is rarely reported in the literature. We experienced a case of solitary spinal cord compression with paraplegia in recurrent ovarian cancer patients.
