[Phosphohexose isomerase in psoriasis]. 
--The authors study in psoriasis an enzyme of the glucolytic way, the Phospho-hexose-isomerase.  --They find significant high levels in blood and damaged skin, while these were "normal" in healthy skin.  --Phospho-hexose-isomerase acts as a biological marker in psoriasis, and acquires the significance of an active cellular proliferation.  --The highest values are those of the erythrodermaes which become normal with clinical involution.  --The authors suggest that psoriasis, by an exaggerated cellular division inhibition mechanism, metabolism is deviated in order to bring the energetic elements and substrate to form the new cell.  --Phospho-hexose-isomerase is not specific of the malignant process.
