Cytokines are hormone-like proteins which mediate and regulate inflammatory and immune responses. The purpose of this study was to investigate the effect of lipopolysaccharide (LPS), Staphylococcus enterotoxin B (SEB), and Mycoplasma lysates on regulation of IL-6 and IL-8 production by human nasal fibroblasts. Primary cultured cells were incubated with LPS (1.0 ug/ml) from E.coli, SEB (1.0 ug/ml) from S.aureus, or Mycoplasma lysates (M.pneumoniae, Mp; M. fermentans, Mf; M. hominis, Mh, each 1.0 ug/ml). The culture supernatants were collected at 2, 6, and 24 hr and assessed for IL-6 and IL-8 production by enzyme-linked immunosorbent assay. The production of IL-6 in the culture supematant was downregulated by LPS, SEB, or Mycoplasma lysates. But IL-6 was upregulated by mixed exposure with Mp+LPS (2 hr), Mp+LPS+SEB (24 hr), Mf+LPS (24 hr), Mf+LPS+SEB (2 hr), Mh+LPS (24 hr), Mh+SEB (24 hr), or Mh+LPS+ SEB (24 hr). The production of IL-8 in the culture supematant was similar to that of IL-6 by same stimulants. But IL-8 was upregulated by mixed exposure with Mf+LPS+SEB (2 hr), Mh+LPS (24 hr), Mh+ SEB (24 hr), or Mh+LPS+SEB (24 hr). These studies show that costimulation of LPS or SEB with Mycoplasma whole cell lysates upregulates the production of IL-6 and IL-8.

Calvarium protects the brain, the most important organ. The defect of calvarium results in not only deformity but also fatal injury from the trauma. The cranial bone defects result from 1) removal of bone flap for intracranial decompression or infection 2) fracture 3) excision of tumor 4) craniectomy for craniosynostosis. The goals of cranioplasty are to protect the brain from trauma and make the aesthetically acceptable contour. From 1990 to 1995, we experienced twelve cases of cranioplasty using autogenous bone graft; 5 cases with rib bone, 3 cases with iliac bone, 2 cases with calvarial bone, and 2 cases with rib and calvarial bones. The result was very excellent without any significant complications.

We report a case of fixed-type sporotrichosis in a 12-month-old infant, who presented with a well-defined scaly erythematous patch on the right lateral nasal root area of approximately 2.5 months duration. Hiopsy revealed pseudoepitheliomatous hyperplasia with chronic granulomatous inflammation in dermis and PAS-positive fungal spores in the stroma. Sporothrix schenckii was identified with fungal culture of biopsy specimen. The lesion was responded to treatment. with itraconazole(3mg/kg) for 12 weeks, without relapse at 5-month follow-up.

A 24-year-old patient who had a history of right-side orchidopexy 16 years ago presented with right testicular pain. A hypoechoic mass was seen on the ultrasonography. Inguinal orchiectomy of the right testis was performed. On microscopic examination, the specimen was identical as an embryonal carcinoma.
