PURPOSE:The most important regulatory factor for IGF-I and IGFBP-3 known so far GH and food intake. Poor nutrition in children with acute lymphocytic leukemia(ALL) increase morbidity during treatment. The aim of this study was to assess the changes of serum IGF-I and IGFBP-3 concentration during induction chemotherapy in 13 children with acute lymphocytic leukemia. METHODS:13 children aged between 1.6 and 13.5 years with ALL were studied the changes of serum IGF-I and IGFBP-3 concentration before, at 2 and 4 weeks after induction chemotherapy. Serum IGF-I and IGFBP-3 were measured using radioimmunoassay. Results : 1) Mean serum IGF-I and IGFBP-3 concentration before induction chemotherapy in ALL patient was significantly lower than the those of normal control(p<0.05). 2) Mean serum IGF-I and IGFBP-3 concentration at 2 weeks of induction chemotherapy were significantly higher than the those of the basal levels (p<0.05). 3) Mean serum IGF-I and IGFBP-3 concentration at 4 weeks after induction chemotherapy were significantly higher than the those of the basal levels (p<0.05). Conclusion : Concentration of serum IGF-I and IGFBP-3 in patients with ALL were significantly increased during induction chemotherapy. These results are probably related to improvement of nutritional status following induction chemotherapy.

Backgroud : The number of proliferating cell populations in the hair is follicles is closely related to the regulation of hair growth. Destruction of hair germ cells and the loss of proliferating cells have been suggested to be of major pathogenetic significance in alopecia areata OBJECTIVE: The purpose of this study is to compare the growth frrections in proliferating cells of normal hair follicles with those in alopecia. METHODS: An immunohiatochemical study was done to detect the proliferating cells in hair follicles using a monoclonal antibody against proliferating cell nuclear antigen(PCNA) in the scalp biopsy of an alopecia patient on the peraffin embedded sections. RESULTS: A significant decrease of the labelling indeces of PCNA were observed in the hair follicles of alopecia compared with normal condition. But we could not find significant differences of labelling index in the clinical types of alopecia, responses to treatment, anc systemic immunologic state. CONCLUSIONS : Whole the above results confirmed that significant decreases of proliferating cells in the hair follicle could explain the part of the pathogenetic mechanism in alopecia, its direct cause which inhibit the proliferation of cells is not clear.

A 7-year-old girl had a 7 × 6cm sized dark red colored tumor on the left elbow and several erythematous macules on the face, right upper arm, and both thighs. Her general health was good and all laboratory findings were within normal limit. Histopathologic examination revealed an infiltration of atypical mononuclear cells in the dermis and subcutis. L26 and leukocyte common antigen were positively stained in an immunohistochemical study. According to clinical, histological and immunohistochemical findings, we diagnosed the disease as primary cutaneous B cell lymphoma. The patient's skin lesions markedly improved after a surgical excision and chemotherapy.

We noticed a group of thoracolumbar and lumbar spine fractures showing a unique fracture pattern that consisted of 1) superior disc injury, 2) crush fracture of the upper half of the vertebral body, 3) sagittal fracture of the lower half of the vertebral body, 4) bone fragments in the spinal canal, and 5) lamina fracture. Some of these fracture patterns were present in type B burst fracture of Denis classification. The purpose of this study was to compare the difference between crush-cleavage fracture and type B burst fracture in the viewpoint of neural canal involvement and neurologic status, and functional outcome with surgical treatment. Ten cases were identified as crush-cleavage fractures in 22 type B burst fractures during a 5 year period from Mar. 1989 to Jun. 1993 at the Department of Orthopedic Surgery of Chonbuk National University Hospital. Four out of 10 crush-cleavage fractures and 4 out of 12 type B burst fractures were paraparetic. Crush-cleavage fracture must be an unstable thoracolumbar comminuted fracture, but there were no significant differences in the neural canal involvement, incidence of neurologic deficit, and in the functional outcome, compared with type B burst fracture (P>0.05). It could be classified as a progressed form of type B burst fracture in Denis classification, or as a burst-split fracture in Magerl classification in the anatomical viewpoint. In conclusion, crush-cleavage fracture must be a variant of burst fracture.

Emphysematous gangrene of the lower extremity in a diabetic patient due to minor trauma is being presented. The gas originating from the extremity extended along to fascial planes into the pelvic cavity, scrotal region, retroperitoneal space, and abdominal wall. CT demonstrated the pathways of upward extension of emphysematousgangrene. Anatomic pathways of the spread of the disease are insertions of the iliopsoas, piriformis and obturator internus muscles, and their fascial investments, and the endopelvic fascia. Anatomic pathways on CT and the roleof CT are discussed.

Porcine reproductive and respiratory syndrome virus (PRRSV), a member of the genus Arterivirus in the family Arteriviridae, is the most important viral pathogens in swine industry worldwide. Here, we have investigated 5' and 3' cis-acting RNA elements required for PRRSV genome replication. Using the infectious PRRSV cDNA, we have manipulated the genomic RNA to generate mutant genomic RNAs, transfected these mutants into susceptible MARC-145 cells, and examined the competence of RNA replication. We found three genetic factors that were essential for viral replication. First, the cap structure present at the 5'-end of the genome was absolutely required for RNA replication. Secondly, polyadenylation of the genomic RNA at the 3'-end was also essential for RNA replication. Thirdly, approximately 100-nucleotide region just upstream of the N protein-coding region was crucial for genomic RNA replication. Taken together, our findings indicate that replication of PRRSV genomic RNA requires three important cis-acting RNA elements: 5' cap structure, 3' poly(A) motif, and an internal sequence of about 100 nucleotides. Further investigation is needed to elucidate the molecular mechanism(s) of how these elements act on PRRSV genome replication.

To investigate the relationship between calcium oxalate stone formation and pathological change of the rat kidney, the early phases of calcium oxalate crystal formation in rat kidneys after intraperitoneal challenge with sodium oxalate were examined at various time interval. The number, size and distribution of the calcium oxalate particles, which were formed intraluminally in proximal tubule, depend on the pathological change according to the time interval after its injection. Tubular obstruction and dilatation due to cellular edema followed by necrosis of tubules and interstitial inflammation were related with increase in number and size of the calcium oxalate particles.

BACKGROUND: Flow cytometric study has been used to measure the DNA content of solid tumors for the last decade. DNA ploidy is an important property commonly measured by flow cytometry. The possibility to study archival paraffin-embedded tumors has hastened an appreciation of prognostic utility of this method. The aim of this study is to look for biologic prognostic indicator for survival time of patients with small cell carcinoma of lung in addition to the well known clinical prognostic factors. METHOD: DNA ploidy was measured by flow cytometric method using tumor cells isolated from paraffin embedded tissue. To evaluate the prognostic significance, DNA ploidy of small cell lung cancer was analysed in 42 patients who died after receiving anticancer chemotherapy. RESULTS: 1) Mean survival time of all patients was 190(+/-156) days. Survival time was shortened, when TNM stage and PS scale were advanced. 2) 62% of all patients was DNA aneuploidy. DNA ploidy had nothing to do with advance of TNM stage and PS scale. 3) Mean survival time of aneuploid tumor was significantly shorter(138+/-90 days) than that of diploid tumors(272 +/- 197 days).(p <0.001) 4) To exclude the influence of clinical prognostic factors such as TNM stage and PS scale, the analysis was restricted to subgroups of identical stage. We were able to find the same tendency. CONCLUSION: DNA ploidy is an independent prognostic factor in small cell lung cancer.
