[Human serum hexosamine. Determination in Brazilian pemphigus foliaceus].

Abstract

The serum hexosamine levels of 39 patients with Pênfigo Foliáceo Brasileiro were determined. The mean value obtained, compared with the mean value found in 30 normal individuals in our laboratory, by Santos et al. (1977), shows that in this disease, the levels of serum glycosamine are higher than in the normal group. The application of Student's test (/t/) indicates a significant difference in the mean values (/t/) = 9,02 P greater than 0,001). Although little is known about the fundamental processes concerned with the increase of serum glycosamines, the authors based on the suggestions of Seibert et al. (1947) reason on the possibility that the essential lesion, i.e., the destruction of the intercellular cement (of glycoprotein nature) is an important factor in the increase of glycoproteins rich in glicosamines.
