[Disseminated pigmented nevus syndrome].

Two patients carriers of a neuro-cutaneous syndrome showing scattered pigmentary nevus and neurologic disorders are exposed, who are added to three similar cases presented in a previous publication. Differences with other syndromes that show cafe-au-lait spots, like those of Recklinghausen and Albright, and also of other known publications, are remarked. Ultrastructural studies are contributed. The denomination of "disseminated pigmentary nevus syndrome" is proposed in comparison with the epidermal nevus syndrome.

[Chemiluminescence of oxygen radicals. A computerized method for its evaluation].

The measurement of oxygen free radicals (O2-) production after polymorphonuclear leukocytes (PMNLs) stimulation may be useful to elucidate the pathogenesis of rheumatic disorders and to assess the efficacy of anti-inflammatory and anti-rheumatoid drugs. The Authors describe a computerized method (with original specific analogic/digital converter and software) which allows a rapid and accurate determination of O2- production and a prompt storage of the data. The Authors, in disagreement with the current opinion, believe that PMNLs activity is more truly expressed by the total amount of emitted energy in a defined interval time than by the peak of emitted energy.
