The immunocompetence is important not only to kill the neoplastic cells but also to keep the neoplastic cells from growing further. T lymphocyte is plays the most important role in maintaining the tumor immunity efficiently. T lymphocyte has its specific functions depending in the subset of T lymphocytes. The author analyzed the T lymphocyte subsets in 31 brain tumor patients using anti-CD3, anti-CD4, anti-CD8 monoclonal antibodies and flow cytometry to determine the immunological status of brain tumor patients. All CD3, CD4 and CD8 subsets were reduced in both benign and malignant brain tumor patients but more signigicantly reduced in malignant tumor group. But in benign tumor group, the subtypes of T lymphocytes were not so different from those of normal healthy controls except the pituitary tumor patients, who showed the significant decrease in all the subtypes. In malignant tumor group, each subtype was signigicantly reduced and CD8 subtypes was markedly reduced in metastatic tumor patients, These analyses were considered to have the possibility to be contributable to planning the further immunotherapy and also the possibility to moniter the brain tumor patients clinically.

Malignant melanoma of the spinal cord is a rare tumor 3,8,9,12 The melanomas that originate in the meninges bear a general structural resemblance to those arising elsewhere, but it is questionable whether they ever metastasis outside the central nervous system7. If can be also argued that the primary central nervous system melanoma could actually be a metastasis from an occult primary site in the skin, esophagus, rectum or other sites6. We are reporting a case of malignant melanoma involving the cervical spinal meninges and hard palate.

In 1921, Dandy discussed the clinical diagnosis and treatment of hydrocephalus secondary to occlusion of the foramina of Magendie and Luschka. In 194, Walker reported a case of congenital atresia of the outlets of the fourth ventricle treated surgically. Since a detailed study of this disease entity by Benda in 1954, the condition has commonly been known by the term, the Dandy-Walker syndrome. In 1968, Raimondi and et al refered this condition as the Dandy-Walker cyst. There is considerable discussion as to the nature of the fundamental embryologic error in this condition, but Denda suggested that atresia of developing fourth ventricular foramina was only a part of the syndrome and not its cause, because in some cases reported, the foramina were found to be patent. These patients. Show characteristic clinical symptoms, signs and radiological findings and should suggest the correct diagnosis. This syndrome was one of the first cause of hydrocephalus to be treated successfully by surgery. We are reporting one case of this cyst encountered recently at Yonsei University Medical Center.

Purpose:
This study examined the patient-reported outcome scores at mid-term follow-up after arthroscopic labral preservation in patients with borderline hip dysplasia.
Materials and Methods:
Data were collected retrospectively from patients who underwent arthroscopic labral preservation. Among the 61 patients classified with hip dysplasia, patients with arthritis beyond Tönnis grade II were excluded, Patients with subchondral bony exposure were excluded even if they had arthritis of Tönnis grade I. Forty-two patients with borderline hip dysplasia were enrolled among patients whose lateral center edge angle (LCEA) was between 18° and 25°. The PRO scores including the modified Harris hip score (mHHS), hip outcome score activities of daily living (HOS-ADL), hip outcome score sport-specific subscale (HOS-SSS) and visual analog scale (VAS), were collected and compared preoperatively, and then at one year and a minimum of five years after surgery.
Results:
The mean preoperative LCEA and Tönnis angle were 20.9° (range, 18° to 25°) and 6.3° (range, 0° to 18°), respectively. The mean follow-up was 64.8 (range, 60 to 84) months. The mean mHHS increased from 73.5 before surgery to 86.2 in the fifth year after surgery (p<0.01), the mean HOS-ADL from 70.5% before surgery to 84.9% in the fifth year after surgery (p<0.01), and the mean HOS-SSS from 51.4 before surgery to 69.4 in the fifth year after surgery (p<0.01). The mean VAS score improved from 6.3 before surgery to 1.5 in the fifth year after surgery (p<0.01).
Conclusion
Arthroscopic labral preservation performed in appropriately selected patients with borderline dysplasia showed good results at mid-term follow-up. In borderline hip dysplasia without the progress of osteoarthritis and subchondral bone exposure, arthroscopic labral preservation may be considered a good and less invasive option.

The serologic tests for syphilis including VDRL and TPHA tests were performed on generaI entertainers in Jung Ku and Young Deung Po Ku, and prostitutes including general entertainers in the Pa Ju area from January 1978 to June 1978. In the same period, direct vaginal smear with Gram stain and culture in Thayer-Martin media were carried. aut for all the general entertainers in Jung Ku and Young Deung Fa Ku as well as for the prostitutes in the Pa Ju area. The results were as follows: 1. An overall VDRL reactive rate of 5, 6 A was found among the 6, 666 general entertainers and prostitutes studied. The reactive rate of VDRL test was 5.3, in 5,289 general entertainers, and 7.6% among the 837 prostitutes in the Pa Ju area. 2. With regard to the VBRL quantitative test, the reactive rate of the group with a titration of 1: 8 or higher rvas 34.8, among the general entertainers of Young Deung Po Ku and Jung Ku. 3. The overall biologic false positive rate of VDRL test was 16.8% in the Young Deung Po Ku and Pa Ju areas using the TPHA test as the standard. 4. The positive rates of culture in Thayer-Martin media were 8.6% out of 1,387 general entertainers of Young Deung Po Ku and l.3% out of 4,352 in Jung Ku respectively, and 2.5 out of 326 prostitutes in the Pa Ju area. The findings seem to be probable that no remarkable change of the incidence of syphilitic and gonococcal infection has taken place recently among the genera. entertainers and prostitutes.

BACKGROUND: Neopterin is released from monocytes/macrophages specifically by stimulation with interferon-γ. Therefore the increase refers to the activation of T lymphocytes. OBJECTIVE: Our objective was to examine the potential role of neopterin in the cell mediated immune response to Behçet's disease. METHODS: We studied 67 patients of Behçet's disease classified by Shimizu and a control group of 30 normal healthy people. Serum neopterin was detected by radioimmunoassay technique. RESULTS: The serum neopterin concentration of the group with Behçet's disease was significantly elevated, compared with the control group (6.36 nmol/ml vs 3.63 nmol/ml). The increase of neopterin concentration was well correlated to the clinical severity of the diseases in increasing order. CONCLUSION: Our data suggest that the T lymphocyte derived IFN-γ which stimulates the production of neopterin has some role in the pathogenesis and clinical severity of Behçet's disease.

BACKGROUND: Although the precise pathogenesis of the Behçet's disease is not yet undertween the severity of Behçet's disease and the serum cytokine level. development of cytokine research has made it possible to find out if there is an association between the severity of Behçet's syndrome and the serum cytokine level. OBJECTIVE: Our purpose was to elucidate whether the immunopathological mechanism is associated with the serum tumor necrosis factor (TNF) and interleukin-1β (I1,1β) which are predominantly produced by monocytes/macrophages, and mterleukm-6 (IL-6). METHOD: Sixty seven patients of Behçet's disease and ten healthy adults as a control group were studied. Serum TNF and IL-6 levels were detected by enzyme immunoassay and serum IL-lβ levels by radioimmunoassay. RESULTS: There were no statistically significant differences in the serum levels of TNF, IL-1β, TL-6 compared with the control group. CONCLUSION: These data suggest that the immunopathological reactions of the Behçet's disease are not associated with a monocyte/macrophage dependent mechanism, possibly due to other immunocompetent cells.

The authors have used a B-mode real-time sector scanner and a 10-MHz probe for measurement of the skin thickness at 21 different sites in healthy Koreans. Subjects consisted of 35 adults(17 males, 18 females) who were divided into three age groups .' young(20 39 years, 12 subjects), middle-aged(40 59 years, 13 subjects), and old(over 60 years, 10 subjects). The results were as follows. 1, The measurements of the skin thickness in examined sites varied from 1.99 to 4.59 milimeters . flexor aspect of the upper arm, dorsum of the hand, extensor aspect of the forearm and flexor aspect of the forearm were thinner, and heel, upper back, metatarsus were thicker than other sites. 2, The skin thickness in males was generally thicker than that in females '. cheek, extensor aspect of the thigh were highly significantly thicker (p<0.01), and chest, upper back, lower back, flexor aspect of the upper arm and extensor aspect of the lower leg were significantly thicker(p< 0.05) in males than in females, 3. The skin was thickest in the old age groups.
