Alveolar hydatid disease of the liver. An experience based on 20 cases. II. Pathology (author's transl)

A three-factor factorial experiment was performed to assess the efficiency of lipid extraction from the back of human volunteers. Chloroform-methanol (2:1 v/v) proved substantially superior to acetone or diethyl ether. The latter two solvents were also significantly more efficient than n-hexane. The implication of the findings is discussed with regard to the isolation and characterization of fungistatic and bacteriostatic agents on the surface of the skin.
