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.

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.

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.

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.

BACKGROUND: Interleukin-2 receptor (IL-2) is expressed and released predominantly activated T lymphocyte. Increased serum levels of soluble IL-2R have been noted in a variety of autoimmune diseases and in conditions associated with T lymphocyte activation. OBJECTIVE: We aimed to examine whether the T lymphocyte activation has any association with the pathogenesis of Behçet's disease. METHOD: We have measured the serum level of soluble IL-2R in serum samples obtained from 67 patients with Behçet's disease and 30 healthy people as a control group, using a double-antibody sandwich enzyme-linked immunosorbent assay technique. RESULTS: Serum soluble IL-2R levels were found to be significantly elevated in the group of Behçet's disease as compared with the control group. No significant differences were found within clinical subtypes of Behçet's disease. CONCLUSION: These findings suggest the presence of an ongoing T lymphocyte activation in this disease process.

10.Anesthetic management of ophthalmic surgery.
Korean Journal of Anesthesiology 2009;57(5):553-559
Ophthalmic surgery presents challenges for the anesthesiologists, including control of intraocular pressure, prevention and management of the oculocardiac reflex. In addition to understanding ocular anatomy and physiology, the anesthesiologists must have possess technical expertise and knowledge of ophthalmic drug's systemic effects. Patients undergoing ophthalmic surgery have extremes of age and several medical diseases, like as hypertension, diabetes mellitus, coronary heart disease, chronic renal failure, and chronic obstructive lung disease. Anesthesiologist should be knowledgeable about the content as stated above to perform safe and desirable anesthesia for ophthalmic surgery.
