[Changes in porphyrin metabolism of mice given beryllium and/or zinc].

Sangyo eiseigaku zasshi = Journal of occupational health, 1997
Beryllium chloride and/or zinc chloride were intraperitoneally injected into mice. The amount of beryllium (Be) injected corresponded to 1/10th of the LD50 dose intravenously administered. The amount of zinc (Zn) injected was the same as Be. The changes in porphyrin metabolism of the mice were studied.
