【Abstract】 Glutaraldehyde fixed tissue block(< lmm) of teleost testis were permeabilized with de-tergent Triton X-100 (0.0002%) and stabilized with saponin (0.002%) during the cytochemical reaction based cerium. The results in this study have shown that this mathod is a successful and efficient method to locate phosphatases of intracelluar sites in no-sliced tissue blocks.Traditional. lead method and periodic / thiocarbohydrazide / silver proteinate cytochemical stain technique also have been used to the same materials. The comparision of cerium/cell permeabilization and routine lead method has been disscussed in the paper. It can be clearly seen that the use of cerium as a cytochemJcal probe for phosphatases has many advantages over lead technique.更多还原
