TREATMENT OF TEST MATERIAL PRIOR TO TESTING
All the concentrations and dose-levels were expressed as active item taking into account the purity of 59.8%. Before preparation, the vehicle was degassed by sonication for at least 15 minutes and then saturated with nitrogen gas, and kept under nitrogen atmosphere for 15 minutes. The test item dosage form was prepared extemporaneously under nitrogen atmosphere (under magnetic stirring) and protected from light. They were kept under nitrogen gas and protected from light before being used within 30 minutes/1 hour after preparation. The test item was ground to a fine powder using a mortar and pestle, dissolved in the vehicle in order to achieve the concentration of 100 mg/mL (expressed as active item) and then homogenized using a magnetic stirrer. Using a treatment volume of 20 mL/kg, the target dose-level was 2000 mg/kg. - Radiolabelling:

- CRITERIA FOR DOSE SELECTION:
On the basis of a previous bone marrow mouse oral micronucleus test (CIT/Study No. 11042 MAS), which was conducted with the same compound up to the maximum dose of 2000 mg/kg (i.e. 1086 mg/kg when expressed as active item) and which was negative, a limit test at 2000 mg/kg (expressed as active item) was performed .
PRINCIPLE :
The serum samples were deproteinized by addition of methanol. The clear supernatant (containing the test item) was analyzed by reversed phase chromatography (HPLC) with detection at 560 nm. - Details on dosing and sampling:

Applicant's summary and conclusion
- Conclusions:
- Under experimental conditions of this study, the Acid Violet 43 after oral gavage at 2000 mg/kg was found in serum of treated rats at each time point samples. The study showed a systemic exposure of rats after oral gavage.
- Executive summary:
This GLP compliant study was performed to assess a potential systemic exposure in rats which were treated orally with the registered substance Acid Violet 43. This study was performed on satellite animals used for in vivo micronucleus assay.
3 rats per sex and per time point group were dosed orally by gavage. At 15 minutes, 30 minutes and 1 hour, blood was sampled in orbital sinus. Serum was isolated and deproteinsed. The amount of the test item was measured by a HPLC-UV method and calculated by interpolation with a calibration curve (made with known concentration curve) by linear regression analysis with the serum blood samples.
Under experimental conditions of this study, the Acid Violet 43 after oral gavage at 2000 mg/kg was found in serum of treated rats at each time point samples. The study showed a systemic exposure to the test item of rats after oral gavage. No clastogenic effects were reported.
