On page 224 in the 5 July 2012 issue, there is an error in the text. The third sentence of the “Histologic and immunohistochemical analysis” section, “Histofine simple stain MAX PO (Rat) kits” should have read, “Histofine simple stain MAX PO (R) kits.” The sentence reads, “Histofine simple stain MAX PO (Rat) kits and subsequently diaminobenzide (DAB) solution (Nichirei Biosciences) was used to generate brown-colored signals.” The sentence should have read, “Histofine simple stain MAX PO (R) kits and subsequently diaminobenzide (DAB) solution (Nichirei Biosciences) were used to generate brown-colored signals.”
