Medial meatal fibrosis is a rare condition in which the medial portion of the external auditory canal is obliterated with fibrous tissue. We selected 4 cases of patients with medial meatal fibrosis with a history of recurrent otorrhea who underwent surgery during the years of 2012 and 2013, presenting the surgical results here. Physical examination showed an obliterated external auditory canal ...

Tail skin cuffs have been grafted to the upper forelimb of red-backed salamanders in either normal or 180 degrees-rotated dorsoventral orientation. Subsequent amputation through the graft region resulted in arrested regeneration, distally deficient or typical four-digit regenerates. Distribution was not substantially influenced by graft orientation nor were there any supernumerary limbs induced...

Gross and microscopic observations of skin homograft rejection carried out in cortisone-conditioned and non-conditioned rabbits seem to indicate that humoral antibodies play an important role in the phenomenon. Thus, local administration of isoimmune serum to animals bearing skin homografts resulted in a significantly earlier rejection of that particular test graft without modifying the course ...

Immunoglobulin G (IgG) has been shown to protect graft rejection after transplantation, whereas the molecular mechanism of IgG in promoting graft acceptance has not been well established. In this study, we tested the effectiveness of IgG in preventing rejection of transplanted skin graft in an immunologically potent rat model, and studied the mechanism of this protection. We found that systemic...
