The liver biopsies were performed with Menghini's needle and the material was histologically and cytologically examined. Liver involvement was found in 9 (27%) patients.

A biochemical characterization of human breast tumors.

The activities of PHI, LDH and LDH isoenzymes were examined in 45 samples of human breast tissue. There were 25 carcinomas, 10 fibroadenomas and 10 nontumor tissue samples. In the group of nontumor breast tissue, values were as follows: PHI (X = 574 SD = 69), LDH (X = 634 SD = 91), LDH5/LDH1 (X = 0.
