The first normal oral mucosa epithelium in which γ-glutamyl transpeptidase activity has been detected
A portion of consistently γ-glutamyl transpeptidase-positive epithelium in the normal oral mucosa of rats is described. This is the first normal oral mucosa epithelium reported to express activity of the trans...

Simultaneous analysis of skin response to the different L.E.T. regions of a 55 MeV helium ion beam
Rat tail epidermis was used to analyze the in vivo response of a biological system to heavy particle irradiation. The conical configuration of the rat tail gives rise to a variable energy degradation of the be...
