The study was undertaken to clarify any quantitative abnormalities in peripheral blood T lymphocytes and T subsets, mediating cell meliated immunity, and the presence of any relation between the degree of quantitative abnormalities and extent of skin lesions and activity of disease in patients with psoriasis by monoclonal antibodies. The results were as follows. 1. Mean percentages of total and suppressor T lymphocytes in 39 patients with psoriasis are significantly decreased as compared with those in 32 controls. Mean ratio of percentage of helper T lymphocytes to that of suppressor Tlymphocytes in 39 patients with psoriasis are significantly increased as compared with that in 32 controls. 2, As classified into three groups according to extent of skin lesions (E: less than 5% E,: 5-30%, and E,: more than 30%), mean pereentages of total T lymphocytes in E, and E, psoriasis group and those of suppressor T lymphocytes in all three psoriasi., groups are significantly decreased as compared with those in controIs. Mean percentages of helper T lymphor,ytes in L psoriasis group and mean ratios of percentage of helper T lymphocytes to that of suppressor T lymphocytes in E, and E, psoriasis groups are significantly increased as compared with those in controls. 3. Cis classified into three groups according to activity of disease (A,: stationary, A,: active, peripherally spreading and A,: active, small papules spreading), mean percentage of total T lymphocytes in peripheral blood lymphocytes in A, psoriasis group and those of suppressor T lymphocytes in all three psoriasis group are significantly decreased as compared with those in controls. Mean percentages of helper T lymphocytes and mean ratios of percentage if helper T lymphocytes to that of suppressor T lymphocytes in A, and A, psorixsis groups are significantly increased as compared with those in controls. These results clarified that there are quantitative abnormalities in peripheral blood I' lymphocytes and T subsets in patients with psoriasis and the degrees of abnorrnalities are related to extent of skin lesions and activity of disease. The aanorrnalities in peri.pheral blood T lymphocytes and T subsets in patients with psoriasis seem to be attributed to primary defect of suppressor T lymphoytes.

Traumatic loss of a finger in part or in which inevitably leads to significant functional deficit and a distortion in body image of the inflicted individual. The available reconstructive option in these circumstances have been toe to finger transfer using microsurgical technique, flap coverage after bone graft, and osteodistraction of the remnant finger. Each method carries advantages and drawbacks inherent in the technique, and generally requires long operative time and hospitalization. Furthermore, the postoperative results after such procedures can be said to be less satisfactory in aesthetic perspectives. Apart from the toe to finger transfer, not much can be sought in terms of functional recovery of the reconstructed part, For a long time finger prosthesis have been used as a replacement of the lost finger part, but it fails to deliver functional strength and tends to be dislodged rather easily. To overcome these shortcomings in the technique, an osseointegrated finger prosthesis has recently been devel-oped. Thumb, index and middle finger in 3 patients were reconstructed with this osseointegrated finger prosthesis. The procedure requires two procedures; the first stage involves placement of a titanium screw in the phalangeal or metacarpal bone proper, followed by fixation of an abutment onto the titanium screw 3 months after the primary operation. The skin surrounding the abutment is thinned out to minimize mobility of the prosthesis at this second stage of operation. After wound stabilization in 2-3 weeks, a custom-made silicone finger prosthesis is made and attached to the implanted abutment using super power magnets. The entire procedure requires 4 months up to the completion, but the procedures can be carried out on the outpatient basis under local anesthesia, not having to interfere with the daily activities of the patient. The aesthetic results with osseoperception have been found to be rewarding, and usual activity like a hand writing and typewriting have been possible. This alternative method could be used for finger reconstruction in cases of usual reconstructive surgery being impossible.

The authors studied the ultrastructural changes of liver cell mitochondria in autolysis. The male Sprague-Dawley rats, weighting 140~160 gm were sacrificed for extract liver tissue. The slices of the liver tissue were incubated in 37 degrees C aseptic normal saline, and those were examined by following intervals; 10, 20 and 30 minutes and 1, 2, 6, 12 and 24 hours with light and electron microscope. The results obtained by light microscopy were summerized as follow. Several fine intracytoplasmic vacuoles were observed 1 hour after incubation. After 3 hours, focal destruction of cytoplasmic membrane with pyknosis of nuclei were observed. More delicate intracytoplasmic architectural changes could not be detected at light microscopic studies. The cord arrangement and cellular boundaries were relatively well preserved until 24 hours after incubation. Electronmicroscopically, mild intramitochondrial swelling with diminution of intramatrical granules were observed at 20 minutes. These were the earliest findings. Both high amplitude swelling and destruction of mitochondrial membrane were observed concurrently at 1 hour after incubation. The earlier membrane changes were observed at inner membrane with cristae and followed by degeneration of the outer membrane. The intramatrical amorphous dense deposits were observed at 30 minutes when the membranes were not destroyed. These deposits were noted in the other experimental groups which were incubated longer than 30 minutes. More electron dense deposits were observed after 1 hour at that time the membrane changes appeared. Vhe results suggest in this experiment that the earliest autolytic changes of liver cell mitochondria is loss of intramitochondrial granules and the membraneous changes led to the irreversible mitochondiral injury. The appearance of two types of intramitochondrial dense deposits would be an interesting finding needed to require further investigation for the chemical stucture and mechanism of dense deposit formation.

Spinal stenosis is a localized narrowing of spinal canal due to strurctural abnormalities. Its symptoms are obscure, and characterized by chronic, poorly localized, bilateral nerve root compression signs. Computerized tomography(CT) has been accepted as almost an absolute diagnostic method for spinal stenosis after its application in the orthopedic field. During the period of 2 years, from March 1982 to March 1984, 26 cases of spinal stenosis were treated surgically after botlt CT scanning and myelography. We obtained following results about advantage of CT scanning in spinal stenosis. 1. Myelography showed following findings: Hourglass defect 9, Complete block 8, Unilateral focal defect 4, Uniform narrowing 1, Mixed 2, Negative finding 2. Myelographic finding was not specific for spinal stenosis and diagnostic accuracy was inferior to CT. 2. The type of spinal stenosis was identified by CT scan finding. Of 26 cases, 21 cases were degenerative spinal stenosis, of which central stenosis was present in 7 cases, and lateral stenosis was present in all cases. The remaining 5 cases were combined type, and both central and lateral stenosis were present in all cases. 3. The diagnostic accuracy,in localizing the level of stenosis was 61.5% by myelography, and 96.2% by CT scan. CT was especially superior to myelography in the localization of the multi-segmental stenosis. 4. CT gives valuable information about extent and degree of stenosis, especially lateral recess stenosis, thus helping the surgeon to decide on the extent of decompressive lamininectomy preoperatively.
