Lê Dũng Trángough to ensure that the line suffers no serious optical depth effects. This requirement often makes the line of the less abundant species impossible to detect. Hence many experiments yield double isotope abundance ratios by comparing the line strengths if two molecules having isotope substitutions o

Noboru Nakayamacumulated at the present on these elements focusing in particular on their isotopic composition. Study of isotopes is indeed most profitable in the sense that they are less affected than elements by chemical fractionation processes although such processes can be considered and be important (see e.g.

Carlos T. Simpson examination in patients who have attained complete remission (Mathé .., 1966; Sharp .., 1967). A number of methods have been tried to eliminate or reduce extramedullary relapses. Some of these approaches have been directed at a specific site of potential involvement (George and Pinkel, 1965; Frei .

The incidence of late central nervous system metastases has been noted in tunours in which it was previously a rare complication. This is especially true in testicular tumours, sarcomas, and more recently, ovarian carcinoma
