Sacro-iliac joint is, as other joints, the prediIection site of tuberculous or pyogenic arthritis as well as primary or metastatic tumor. The writers reviewed twenty cases of sacro-iliac lesion performed at the Department of Orthopedic Surgery, Seoul National University Hospital, for the period of five years from June 1972 till May 1977. 1. They are tuberculous arthritis eleven, pyogenic arthritis five, ankylosing spondylitis two(one associated with spinal stenosis, the other with hip invoIvement), osteosarcomatosis one, metastatic tumor from adenocnrcinoma of prostate one 2. Infection is the predominant Iesion in sacro-iliac joint, and tuberculous arthritis is twice than pyogenic arthritis. 2. Early diagnosis of sacro-iliac lesion is difficult, but S-I stress test is a valuable finding. 4. Two of eleven cases of tuberculous arthritis, two of five cases of pyogenic arthritis with mild involvement were treated conservatively without sequele, but in more advanced cases, surgical intervention was preformed.

BACKGROUND: Endoprosthetic reconstruction is widely applied for pathological fractures of the proximal humerus; however, functional impairment is usually unsatisfactory. The aims of the current study are to evaluate the reliability of interlocking intramedullary (IM) nailing with cement augmentation as a fixation method in proximal humeral lesions and to assess functional outcomes. METHODS: We reviewed 32 patients with pathological fractures of the proximal humerus who underwent interlocking IM nailing and cement augmentation. Functional scores and pain relief were assessed as outcomes. RESULTS: The mean follow-up period was 14.2 months. The mean Musculoskeletal Tumor Society functional score and Karnofsky performance status scale score were 27.7 and 75.6, respectively. Improvement of pain assessed using the visual analogue scale was 6.2 on average. Thirty-one patients (97%) experienced no pain after surgery. The mean ranges of forward flexion and abduction were 115° and 112.6°, respectively. All patients achieved stability and had no local recurrence without failure of fixation until the last follow-up. CONCLUSIONS: Proximal interlocking IM nailing with cement augmentation appears to be a reliable treatment option for pathological or impending fractures of the proximal humerus in selected patients with metastatic tumors, even with extensive bone destruction.

Uterine tumor resembling ovarian sex-cord tumor (UTROSCT) were first described by Clemen and Scully in 1976. They are a heterogenous group of uterine neoplasm characterised by pure or predominant histological patterns that resembled sex cord tumors of ovary. Clemen and Scully divide the tumors into two groups according to sex-cord-like structures within tumors (the so-called group I tumors with 50% of sex-cord elements, the so-called group II tumors with almost completely sex-cord-like structures). The histogensis of the sex-cord-like elements is uncertain, the group I tumor appears to be more malignant. We experienced a case of UTROSCT in a 44 years old woman underwent LAVH under tantative diagnosis of uterine myoma and report the case with brief review of literature.

BACKGROUND: The importance of the determination of cell viability has prompted the development of several assays of viability that utilize the exclusion of certain dyes by viable cell membranes. Recently, flow cytometry has been adapted to estimate cell viability by using fluorescent dye which is excluded by living cells on the basis of altered dead cell properties. OBJECTIVE: We have developed a flow Cytometric method for measuring cell viability after staining with propidium iodide (PI) and have compared it with the classical colorimetric method, MTT assay, which is currently widely used in cytotoxicity assays in the research field. METHODS: We performed flow cytometry and MTT assay for the comparison of the sensitivity of the assessment of cell viability. RESULTS: Decrease of cell viability was measured by flow cytometry with the addition of as little as 0.002% Triton-X 100 in comparison to MTT assay which could only reveal a similar decrease of cell viability with the new method to 0.008% Triton-X 100. CONCLUSION: Our results demonstrate this new method to be more sensitive and simple for the assessment of cell viability.

BACKGROUND: The severity of several chronic inflammatory diseases was reported to be associated with polymorphism of the IL-1 receptor antagonist gene(IL-lrn). OBJECTIVE: This study was performed to study the polymorphism of the IL-1rn in vitiligo and in the normal Korean population. METHODS: Thirty one cases of vitiligo and seventy nine normal Koreans as control were studied for the polymorphism of IL-1 rn. RESULTS: The frequency of allele 2 of the IL- I rn in 31 patients with vitiligo was compared with that of the 79 healthy controls. The frequency of allele 2 was 1.6% in vitiligo patients and 3.8% in the normal controls. CONCLUSION: There was no significant difference in the frequency of allele 2 between the vitiligo patients and normal controls.
