- Details on study design:
- MATERIAL AND TECHNICAL EQUIPMENT
- Laminar flow bench: HERAsafe KS 18 (Thermo ELECTRON CORPORATION)
- CO2 incubator: Heraeus BBD 6220
- Incubation conditions: 37°C ± 1°C, 5% ± 1% CO2, 90% ± 5% humidity
- Spectrophotometer: SunriseTM Absorbance Reader
- Wavelength: 570 nm without reference filter
- Assay medium: OCL-200-ASY
- Detection agent: 3-[4.5-dimethylthiazol-2-yl]-2.5-diphenyltetrazolium bromide (MTT)
- Extracting agent: Isopropanol p.a
TISSUE PREPARATION:
Preincubation: On the day of arrival in the laboratory, the tissues were transferred to sterile 6-well plates with 1 mL assay medium and preconditioned in the incubator at 37°C. After 1 h, the preincubation medium was replaced with fresh medium and preconditioning continued in the incubator at standard culture conditions for 16 – 24 h.
Pretreatment: After the pre-incubation, the tissues were pre-treated with 20 μL of PBS in order to wet the tissue surface. The tissues were incubated at standard culture conditions for 30 minutes.
APPLICATION OF THE TEST ITEM:
Using a sharp spoon, approx. 50 μL of the undiluted test material was applied covering the whole tissue surface. Control tissues were applied with 50 μL of negative and of positive control. After application, the tissues were placed into the incubator until the total exposure time of 6 h.
REMOVAL AND POSTINCUBATION PERIOD:
To remove the test item, the tissues were washed with sterile PBS. Tissues were immersed and swiveled three times in each of three beakers filled with PBS. Washed tissues were immediately immersed into 12-well plates and pre-filled with 5 mL/well prewarmed medium (post-soak immersion) in order to remove residual test substance. After 25 minutes of post-soak immersion, each tissue was dried on absorbent paper and transferred to fresh 6-well plates filled with 1 mL/well pre-warmed medium.
The tissues were incubated at standard culture conditions for 18 hours (postincubation period).
MTT INCUBATION:
After the post-incubation period, the assay medium was replaced by 0.3 mL MTT solution and the tissues were incubated in the incubator for 3 hours. After incubation, the tissues were washed with PBS to stop the MTT-incubation. The formazan that was metabolically produced by the tissues was extracted by incubation of the tissues in isopropanol at room temperature overnight or for at least 2 hours on a plate shaker. The optical density at a wavelength of 570 nm (OD570) of the extracts was determined spectrophotometrically. Blank values were established of 4 microtiter wells filled with isopropanol for each microtiter plate.
EVALUATION CRITERIA:
A chemical is considered as "irritant", if the mean relative tissue viability with a test material is ≤ 60%.
However a borderline range is statistically determined. Therefore, mean percent tissue viability equal to ± 5% of the cut-off value is considered to be discordant. - Irritation parameter:
