Nt, fixed in formalin, embedded in OCT compound (Tissue Tek, Torrance, CA, USA) and sectioned applying a cryostat. The In Situ Cell Death Detection Kit (Roche Applied Sciences, Indianapolis, IN, USA) was made use of for TUNEL staining. Pictures were obtained making use of a fluorescent microscope (Olympus, Center Valley, PA, USA; IX71). The images have been acquired by Photometric CoolSnap HQ camera (Photometric, Tucson, AZ, USA) employing 20 magnification and imported into MetaMorph computer software (Molecular Device, Sunnyvale, CA, USA). (d) The pictures were enhanced by digital thresholding plus the percentage of apoptotic cells was calculated as total area occupied by FITCstained cells/total area occupied by four,6diamidino2phenylindolestained cell for the same image. The bars represent the imply of apoptotic cells .d.
