cryostat sections from the mesonephros of various pig embryos with a crown-rump-length of between 17 and 95 mm were used for light microscopical assays of acid hydrolases ( acid phosphatase , beta-d-n-acetylglucosaminidase , beta-d-glucuronidase ) , oxidoreductases ( succinic dehydrogenase , nadh- and nadph-tetrazolium reductase ) and adenosine triphosphatases ( mg2+- and na+ -- k+-atpase ) .
