| مستخلص: | Histological methods suitable for use in autoradiographic technics are described. An investigation has been carried out on the amount of activity lost from rat and human tissues during fixation and dehydration. Losses in the processing fluids varied from 25% to 90% of the initial activity for radioactive phosphorus and 4% to 20% for radioactive iodine in various fixatives.The care necessary in handling sections if distribution of total activity is being studied is emphasized and floating on absolute alcohol is suggested as an alternative to warm mercury. Various procedures for staining sections before application of photographic emulsion and after developing are discussed. Ehrlich's hematoxylin applied regressively has given good results and eosin has been used successfully as a counterstain. Orth's lithium carmine is resistant to photographic developer and also Feulgen's stain counterstained with fast green can be used before covering the slides with photographic emulsion. |
