[Chromatographic determination of arylsulfatases A and B in human gastric mucosa].
In continuation of a previous work, we have confirmed the occurrence of arylsulfatase A in 4 samples of human gastric mucosa analysed by the chromatographic procedure described by Stevens et all. By using the chromatographic method we have also evidentiated the occurrence of arylsulfatase B, which was not detected by using the method of Baum et all. The B form was lower than the A form in 3 samples while it was higher in another sample. In the latter sample of gastric mucosa it was also detected the unusual form Bm of arylsulfatase. It was concluded that both forms A and B of arylsulfatase are present in human gastric mucosa, in variable amounts and that the simple procedure developed by Baum et all., although suitable for the analysis of these enzymes in the urine, is not useful for the determination of arylsulfate B in the gastric mucosa.
