Copper and zinc content of human leiomyomas

The copper and zinc levels of leiomyomas were determined and compared to the levels in the uninvolved myometrium and myocervix. In general the levels found in leiomyomas were similar to those of the smooth muscle of isthmus and corpus but different to those of the myocervix. There were no significant differences in the levels found in smooth muscle of uteri with or without leiomyoma.
