[LDH activity in human ovarian tissue and in ovarian carcinoma (author's transl)]

Lactate-dehydrogenase activities were measured from tissue homogenates of 34 human ovaries and ovarian carcinomas. Mean activities were 265.2 nmol/s/g tissue in normal ovaries and 695.1 nmol/s/g in ovarian carcinoma tissue. One and the same ratio was obtained from two comparative group of one and the same age. The above difference was significant. No relationship was found to exist between LDH activity in tumour tissue and stage of the disease.
