[Fatal massive intravascular coagulation during phlebography. Responsibility of epsilon-aminocaproic acid?].

The occurrence during phlebography of massive intravascular coagulation involving the inferior vena cava, the right cardiac cavities and the entire pulmonary arterial network suggested that epsilon-aminocaproic acid administered before phlebography was responsible for this complication. The mechanisms of reactions to contrast media are still poorly understood, but these reactions are known to include, in some cases, disseminated intravascular coagulation. This phenomenon was histologically demonstrated in our patient, and it may be suggested that its strong enhancement by the antifibrinolytic agent had resulted in the fatal accident. In view of the possibility of such lethal reactions, the advisability of administering epsilon-aminocaproic acid--a drug widely used in France for the prevention and treatment of contrast media reactions--should be reconsidered.

[Life cycle of Leranthropus kroyeri Van Beneden 1851, hematophagous branchial copepod of the sea bass Dicentrarchus labrax (Linné, 1758) in wild and experimental populations].

The life cycle of Lernanthropus kroyeri Van Beneden, 1851, copepod (Siphonostomatoida) parasite of Dicentrarchus labrax is described. The cycle comprises two nauplii, one infective copepodid, four fixed copepodids and one preadult. All the attached stages are caracterised by the lack of the frontal filament. This is the first description of a life cycle lacking a chalimus for Siphonostomatoida Copepods parasitic on fish.

[Reproduction and sexuality of parasitic copepods of fishes. I. The reproductive apparatus of Chondracanthus angustatus Heller, 1865: anatomy, histology, and spermiogenesis (author's transl)].

The pygmy males of Chondracanthus angustatus are fixed on the genital segment of the female on two anterior-ventral tubercules. The genital system is formed by two dorsal testes, two broad vas deferens and two seminal vesicles each one containing a spermatophore. Two types of cells can be seen in the interstitial tram: the sexual (normal and abortive) and the somatic ones. The plasmic and nuclear membranes joined together on one end of the spermatid; on the opposite pole, the mitochondria penetrate into the cytoplasmic expansions. The non-motile starfish spermatozoa present neither di-ferentiated acrosome nor centrioles. The male gametes are stocked in the spermatophore and enveloped by many kinds of secretions. Spermatozoa are discharged into the female integument folds and they reach the seminal receptacle with the help of the villosities movement; they stay there till fertilization occurs.
