[Effect of chrome compounds and other chemicals in the content of cement and clincker dust on metabolic parameters++ of lymphoid organs in rats].

Effect of seven-day enteral administration of clinkers, cement and dust sedimented on electric filters on DNA and RNA, total protein levels, adenylate desaminase (AD) and alkaline phosphatase (AP) activities in thymus und spleen was shown in rats. Harmful effect of industrial dust on the lymphatic organs was maximal in thymus: diminished lymphatic tissue, decreased DNA, RNA and total protein levels, increased AD and AP activities. Compounds of chromium with lead, copper and mercury appeared to have maximal harmful effect on the lymphatic tissue.
