Comments

The explanation of the results of the tests is demonstrated in the pictures:

As written in the test above, tests are validated due to comparison with well known materials which are toxic as well as non-toxic.

As well known non-toxic material, (UHMW poly ethelene), is placed in the medium of fibroblasts and shall give no toxic effect.

Lower left:
Material under test:
CMC acupuncture needle materials

Upper right:
Positive control:
A well known toxic material, (pararubber), is placed in the medium of fibroblasts and shall give a strong toxic effect.

Lower right:
