Functional evaluation of pallid mice with genetic emphysema.

Studies on pallid mice models of genetic emphysema have conventionally focused on morphological or biochemical evaluations. However, it is important to consider the functional aspects. We evaluated the exercise capacity and respiratory function in male pallid mice and male C57BL/6J mice at 3, 6, 12, and 15 months of age.

Current status of sentinel lymph node navigation surgery in breast and gastrointestinal tract.

Sentinel lymph node biopsy (SLNB) has been developed as a new diagnostic and therapeutic modality in melanoma and breast cancer surgery. The purpose of the SLNB include preventing the operative morbidity and improving the pathologic stage by focusing on fewer lymph nodes using immunocytochemic and molecular technology has almost achieved in breast cancer surgery. The prognostic meaning of immunocytochemically detected micrometastases is also evaluating in the SLN and bone marrow aspirates of women with early-stage breast cancer.
