Results and discussion

Any other information on results incl. tables

When haemolysates of infantile erythrocytes were mixed with 50, 100, 200 and 500 gamma menthol, the methaemoglobin content rose by up to 100 %, namely from 0.7% to 1.5%; these values values are absolutely within physiological limits.

Applicant's summary and conclusion

Conclusions:
When haemolysates of infantile erythrocytes were mixed with 50, 100, 200 and 500 gamma menthol, the methaemoglobin content rose by up to 100 %, namely from 0.7% to 1.5%; these values values are absolutely within physiological limits.
Executive summary:

in vitro test: 

when haemolysates of infantile erythrocytes were mixed with 50, 100, 200 and 500 gamma menthol, the
methaemoglobin content rose by up to 100 %, namely from 0.7 to 1.5%; these values are absolutely within physiological limits and this effect could be neutralized with vitamin C (test substance: unspecified isomer)
