The in vivo reconstruction of conjunctiva was investigated by using modified poly(lactide-co-glycolide) (PLGA) 50/50 scaffolds. The porous PLGA matrices were prepared by a solvent-casting particulate-leaching method with NaCl, then modified with collagen, hyaluronic acid (HA) or/and human amniotic membrane (AM) component. The growth of corneal epithelial(More)
Histoplasmosis is a very rare disease in Korea. Clinical manifestations are very similar to those of tuberculosis. This is the first case report of combined disseminated histoplasmosis and tuberculosis in a patient with HIV infection in Korea. A 42-year-old Korean with Acquired Immunodeficiency Syndrome (AIDS) was diagnosed with tuberculosis. He had lived(More)
There have been some individual case reports and a few large series of reports describing the clinicopathologic features of follicular dendritic cell sarcoma. This tumor originates from the dendritic cells of lymphoid follicles and is extremely rare in the extranodal location. We report the case of a 68-year-old man who presented with low back pain. A mass(More)
Benign neoplasia of the duodenum are very rare. Moreover, duodenal tubulovillous adenomas are more uncommon lesions. The microscopic structure of tubulovillous adenoma has frond-like projection of mucosa with branching papillary structure and generally upward growth into the lumen. We describe a 72-year-old man who showed aduodenal tubulovillous adenoma(More)
The difficulties encountered in dealing with the bone deficient acetabulum are amongst the greatest challenges in hip surgery. Acetabular reconstruction in revision total hip arthroplasty can successfully be achieved with hemispherical components featuring a porous or roughened ingrowth surface and options for placement of multiple screws for minor(More)
Ordinary heterotrophic organisms (OHO) of an activated sludge wastewater treatment system showed an atypical growth behaviour when they are inoculated to batch aerobic growth tests with a high substrate-loaded condition. For example, the OHO maximum specific growth rates on readily biodegradable substrates (μ H) increased with a high ratio of substrate(More)
