Serum naphythylamidase isoenzymes during hormonal treatment. Electrophoretic and quantitative studies.
Alterations in serum naphthylamidase isoenzymes were studied by electrophoretic and quantitative methods in women treated with oral contraceptives and women treated with naturally occurring conjugated estrogens for climacteric symptoms. In women treated with oral contraceptives the appearance of extra isoenzyme components was accompanied by a distinct and significant increase in the total serum naphthylamidase activity, whereas in treatment with conjugated estrogens no such increase was found. The result suggests that combined oral contraceptives and natural estrogens affect the serum naphthylamidase pattern in different ways.
