PURPOSE:Bone mineral mass increases with age, weight and pubertal development. Several factors influence the process of bone mineralization, and evaluation of bone mineral density(BMD) in children gives important clue to the different mechanisms of bone mass accumulation. To investigate the abnormality in bone mineralization, the normal range of bone mineral content in healthy children should be understood. The pattern, time and velocity in the decrease of bone mineral contents depend on disease entities. Because the ratio of trabecular and cortical bones and turn-over rates differ in each bone, it is needed to make normal data for trabecular and cortical bones respectively in children. METHODS:In 75 children(40 boys) with normal growth and development, BMD was measured with XR26 Bone densitometry using DEXA. The BMD of trabecular bone was obtained at lumbar spine at 2-4 level, and that of cortical bone was measured at femur neck. RESULTS:The BMD of trabecular bone increased with age without sexual difference. But the BMD of cortical bone was higher in male significantly at 8-9 and 10-11 yr of age. In both male and female, the BMD of trabecular and cortical bones correlated positively with age, bone age, height, weight, and body surface area. CONCLUSION: With this data, the changes in BMD affected by several diseases could be assessed.

Prostatic carcinoma is one of the most common malignancies in males of western countries but it is a rare malignancy in Korea. If it occurs, it commonly metastasizes to other organs. In-spite of its high incidence of distant metastasis, the cutaneous metastasis of the prostatic carcinoma is very rare and seems to have a poor prognosis. A 67-year-old man presented multiple nontender nodules on the skin of the right thigh and had episodes of multiple metastases from prostatic carcinoma to the lungs and bones. Histopathologic findings of the skin showed atypical cells infiltration at the dermis. Immunohistochemical staining for prostate specific antigen showed a positive reaction, therefore, we reached the diagnosis of cutaneous metastasis from prostatic carcinoma.

BACKGROUND: The characteristic t(15; 17) of acute promyelocytic leukemia (APL) fuses the retinoic acid receptor alpha (RARA) gene on chromosome 17 to the PML gene on chromosome 15. The test of PML-RARA rearrangement is essential for diagnosis and therapy of APL. We analyzed breakpoints of the PML gene as a basic study for PML-RARA rearrangement test. METHODS: PML-RARA rearrangements, breakpoints of the PML gene and junction sequences were analyzed in 41 patients with APL using RT-PCR and direct sequencing. RESULTS: Forty out of 41 cases revealed PML-RARA rearrangement, of which results coincided with cytogenetic data. Breakpoint distribution was 26 cases in burl (65%), one in bcr2 (2.5%), and 13 in bcr3 (32.5%). Sequencing data showed invariable joining of exon 3 of the RARA gene and exon 6 (bcrl type) or exon 3 (bcr3 type) of the PML gene. One case with bcr2 type had breakpoint in exon 6 of the PML gene with 57 bp deletion. CONCLUSIONS: Bcrl Is the most common breakpoint site of APL in Koreans, and bcy1+2/bcr3 ratio is approximately 2.1. PML-RARA junctions were continuous and joined by a correct splicing event. Breakpoint analysis would be useful in quality control of PML-RARA rearrangement test and the fused protein analysis.

Tbe presence of certain HPV types in the female genital tract was associated with a number of diseases, including condyloma, cervical, vaginal and vulvar intraepithelial neoplasia and carcinoma. It is generally accepted that these viruses are predominantly sexually transmitted. HPV cannot be cultured in vitro, and immunological tests are inadequate. Indirect evidence of anogenital HPV infection can be obtained through the physical examination and by the presence of characteristic cellular changes associated with viral replication in Pap smear or biopsy specimens. Alternately cervical scrapes can be analyzed by nucleic acid hybridization to directly detect the presence of HPV DNA, Historically, HPV 16 and HPV 18 have been regarded as high risk cancer associated HPVs and HPV types 6, 11, 42, 43 and 44 as low risk HPVs. Subsequently HPV types 31, 33, 34, 35, 45, 51, 52, 56 and 58 have been demonstrated to have and intemediate association with cancer, This study was performed for high and intermediate types HPV DNA detection on cervical carcinoma with Virapap Probe B. HPV DNA were detected 82.3% on cervical carcinoma and 7,1% on control samples. HPV DNA test will be apply as a triage for cervical cancer detecting test.

The prognosis of transitional cell carcinoma(TCC) of the urinary bladder is related to histopathologic parameters, among which the clinical stage and histopathologic grade are most important prognostic determiantors. Recently the immunohistochemical assessment of proliferating cell nuclear antigen(PCNA) and nucleolar organizer region number(AgNORs) can obtain the PCNA, and AgNORs stainings were studied in 55 the sequential biopsies of 22 recurrent TCCs of the urinary bladder. 6 cases showed the increased changes of grade, of which 5 cases was independently to the change of grade. The AgNORs in 18 cases showed increase in 10 cases. The comparison between PCNA count and AgNORs score according to grade was performed in the changes between grade II and III, both PCNA count and AgNORs score were increased with in crease of grade. However, The change of the PCNA count was stastically significant, but not AgNORs score.
