[Ulcerative colitis associated with chronic atrophic polychondritis. One case (author's transl)].

A male patient has developed ulcerative colitis at the age of 70. Signs of chronic atrophic polychondritis appeared 9 months after the first attack. Subsequently, during the course of the disease each attack of ulcerative colitis was preceded by an exacerbation of polychondritis, which suggests a causal relationship rather than a chance association between the two conditions. The clinical response of polychondritis to sulfones in daily doses of 200 mg was satisfactory, but this dosage, which at present seems appropriate requires to be confirmed by further observations.

[Associated vertebral angioma and epidural cavernoma (author's transl)].

A 27 year old man developed a pyramidal syndrome with hypoesthesia up to the level of D8, over a period of two months. Radiographic examination revealed the presence of an angioma of D8. Selective angiography demonstrated that there was epidural invasion as well as an angioma of the vertebral body, and enabled embolization of the 2 pedicles of the lesion to be performed. This produced only a partial, temporary improvement, and a posterior epidural tumor was found and removed by operation. The histological appearance of the tumor was that of a cavernoma, and rapid and permanent recovery of normal neurological function was obtained after the operation. The authors discuss the pathogenicity of the neurological disorders associated with single bone angiomas, and the problems raised by their treatment.

[Action of cadmium on a free dinoflagellate Prorocentrum micans E: growth, cadmium absorption and cell modifications].

The study of the growth of Prorocentrum micans E. submitted to sublethal doses of cadmium demonstrated a high sensitivity of this Dinoflagellate to the polluant starting with concentration of 5 microgram/l. The uptake of cadmium was measured by pulse polarographic analysis of the filtered culture medium. Structural modifications, not apparent in living cells, are visible after fixation. The high sensitivity of Prorocentrum micans to cadmium, also its easy culture, makes it a suitable pollution indicator of this heavy metal.
