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.

PURPOSE: The modern era of hypospadias surgery has brought functional and cosmetic results to a high level in children. However, little data are available on the outcome of adult hypospadias repairs. The objective of this study was to evaluate the results of 46 adult patients with hypospadias repairs. MATERIALS AND METHODS: One surgeon performed forty-six consecutive adult hypospadias repairs. The mean age at the time of surgery was 22.1 years (range 13 to 59). Follow up ranged from 3 months to 7 years (mean 11.3 months). We retrospectively analyzed surgical outcomes, with respect to previous repair, surgical procedure and complications. RESULTS: Of 46 adult hypospadias patients, 20 had had previous repairs and 26 had had no previous repairs. Surgical procedures consisted of 7 onlay island flap, 6 pyramid, 4 transverse island flap, 2 King, 3 MAGPI, 2 Mathieu, 3 tubularized incised plate and 1 meatal advance in the group with no previous repairs. In the group that had undergone previous repairs there were 10 Thiersch-Duplay, 2 Johanson, 2 transverse island flap, 1 MAGPI, 1 King, 1 Durham-Smith, 1 Mustard, 1 meatal advance and 1 onlay island flap. Complications developed in 11 patients from the no previous repair group, including 6 fistula, 2 stricture, 4 wound infection, 2 wound dehiscence and 1 ventral curvature, and were as follows for the previous repair group; 12 fistula, 5 stricture, 3 wound infection and 4 wound dehiscence. CONCLUSIONS: For both groups analysed, adult hypospadias repair was much less successful than childhood repair. Further studies are necessary to decrease the complications.

In order to study the efficacy of a 0.2% ciprofloxacin-soaked collagen shield for the treatment of Staphylococcus aureus keratitis, an experimental study was performed on 40 eyes of 20 rabbits. Twenty hours after intrastromal injection with S. aureus, the rabbits were divided into four groups: Group 1(10 eyes) was treated with a 0.2% ciprofloxacin-soaked collagen shield with an additional instillation of 0.2% ciprofloxacin drops every 30 minutes for 4 hours; Group 2 (10 eyes) was treated with a 0.2% ciprofloxacin-soaked collagen shield for 4 hours; Group 3 (10 eyes) was treated with 0.2% ciprofloxacin drops every 30 minutes for 4 hours; Group 4 (10 eyes) received BSS every 30 minutes for 4 hours as a control. Bacterial killing was quantitated by culturing corneal homogenates and calculating the number of viable bacteria (colony-forming units) per cornea. Groups 1, 2, and 3 showed significantly reduced numbers of bacteria compared with the control (p<0.01). The order of efficacy in the treatment for S. aureus keratritis were groups 1, 2 and 3, respectively, but the statistical difference was not significant among groups 1, 2, and 3(p>0.05). These results suggested that a 0.2% ciprofloxacin-soaked collagen shield may be an effective and convenient mode of therapy for S. aureus keratitis.

TGF-beta1 is a potent chemotactic factor for inflammatory cells and fibroblasts. It also stimulates the celluar source and components of extracellular matrix and the production of proteinase inhibitors. Collectively, these biologic activities lead to the accumulation and stabilization of the nascent matrix, which is vital to wound healing. The objective of this study is to investigate production of TGF-beta1 in vitro fibroblast culture in the presence of Staphylococcus enterotoxin B(SEB) and/or lipopolysaccharide(LPS) and to elucidate the role of TGF-beta1 which may be responsible for wound healing The fibroblasts were originated from facial dermis and hypertrophic scar in 26 year-old male patient. In the presence of LPS(0.0l microgram, 0.1 microgram, 1.0 microgram), SEB(0.0l microgram, 0.1 microgram, 1.0 microgram) respectively, cells(5x103ml) were cultivated in vitro. At 1, 3, and 5 days after incubation, cells were counted. Also, cells(2.5x105ml) were cultivated in EMEM with LPS(0.01, 0.1 and 1.0 microgram), SEB(0.01, 0.1 and 1.0 microgram) respectively and LPS(0.1 microgram) and SEB(0.1 microgram) in combination for 24, 48, and 72 hours respectively. Culture supernatants were harvested at 1, 2, and 3 days after incubation period and triplicate culture supernatants were pooled and TGF-beta1 was assayed in duplicate. The results were as follows. 1. In facial dermal fibroblast induced with SEB and LPS respectively or in combination, the suppression of cell proliferation occurred very significantly at 1 day after incubation, compared with the control. In SEB exposure, the production of TGF-beta1 was decreased very significantly at 1 day after incubation, compared with the control. However, in LPS, SEB and LPS exposure, the production of TGF-beta1 was increased very significantly at 1 day after incubation, compared with the control. 2. In hypertrophic scar fibroblast induced with SEB and LPS respectively or in combination, the suppression of cell proliferation did not occur at 1 day after incubation, compared with the control. In SEB and LPS exposure in combination, the production of TGF-beta1 was increased very significantly at 1 day after incubation, compared with the control. However, the production of TGF-beta1 did not occur in SEB and LPS exposure respectively. In conclusion, the concentration of bacterial toxins and the incubation period correlated with cell proliferation and production of TGF-beta1 very significantly and both fibroblasts have different phenotype each other in this regard. This data suggest that the significant production of TGF-beta1 may develope abnormal wound healing associated with tissue fibroproliferative disorder, such as hypertrophic scar and keloid formation.
