Results and discussion

Any other information on results incl. tables

The LD50 of MnCl2 to mice was found to be 255 mg/kg and in rats was 700 mg/kg. The animals died within 3 -5 days of administration of the toxic doses.

Administration of MnCl2 to rabbits at daily doses of 0.5 and 5 mg/kg for 2 months produced no changes in the animals behaviour or condition. No animal died during this experiment.

The blood levels of manganese after administration of 0.5 mg/kg MnCl2 were identical to those in control group animals. When the higher dose of MnCl2 was used the Mn blood level rose.

Rabbits treated with MnCl2 for 2 months showed no variations in the macro- and microexaminations of various body organs and tissues, the weight and histological structure of internal secretory glands and blood sugar levels compared to the controls.

The local irritant action in response to administration of MnCl2 disappears spontaneously following its withdrawal on completion of a course of therapy.
