The radiopharmaceuticals are products that combine two very stringent regulatory requirements from two different authorities: as medicine from a pharmaceutical point of view (Afssaps) and as radioactive source with specific authorization (ASN). This article discusses the different regulatory constraints imposed by these authorities but suggests also that legislation is supposed to be modified in the coming years in collaboration with nuclear physicians and their Society (SFMN).  相似文献

The acrosome reacting capacity of spermatozoa is essential for the fertilization of the oocyte. Several methods are available for the evaluation of the acrosomal status; each method detects a step of the reaction which is a continuous process. Due to the diversity and the relative specificity of each technique, it is difficult to compare results in absolute values. The reaction is Ca++ dependent. The use of Ca++ ionophores is valuable for a dynamic study which gives a better appreciation of the capacity of spermatozoa to react to a specific stimulus. Many authors have attempted to correlate the acrosomal status to the fertilizing ability of spermatozoa. The results show a reduced induction of AR in hypofertile sperm. More studies with standard materials and methods are needed in order to confirm the diagnostic value of this test.  相似文献

This paper sets out to place The Interpretation of Dreams within an historical context. It argues that it is impossible to have complete confidence in Freud’s words when, in his letters to Wilhelm Fliess, he characterized himself as a mere discoverer. In reality, Freud also felt he belonged to a learned community of dream specialists, whom I call “dreaming scientists” and “scientific dreamers”. Here, I offer, as example, a portrait of Freud as a reader of two French authors, Alfred Maury, and, indirectly, Léon Hervey de Saint-Denys. I analyze how Freud positioned himself as Maury’s successor and sometimes experienced dreams like Hervey de Saint-Denys. The premise of this work is that we must set aside Freud if we want to venture into the learned dream culture peculiar to the 19th century. Only afterwards can we return to Freud and place him in this context as a creative heir.  相似文献
