(3)Judgementof the result Judgement (Encircleone) I Reason for judgement: Positive (::@egativeD The test substance did 'notincrease the cells with structural chromosomal aberrationsand polyploidcellswith or withoutmetabolicactivation. These resultsled to the conclusionthat the test substancedid not have clastogenic potential. (4)Referenti.amlatters 1. The test substance was insoluble in water and,DMSO and was soluble in acetone. But the test substance in DMSO was dispersed in culture medium better than that in acetone. ThereforeDMSO was selectedfor solventof the test substance. 2. In the cell growth inhibitiontest,50% inhibitiondose of cell growth (TCID5o) was 60gglmt in 24-hourtreatment.73g g/mt in 48-hourtreatmentwithoutmetabolic activationand 71 gg/mt with metabolicactivation. In all treatmentgroups, cell growth indexat lOOg g/mt or more did not increaseor slightly increasedand this concentrationcoincidewith that beginningto precipitate. So it was considered that the testsubstancewas saturatedat lOOg glmt or more (Fig.1, 2). From these results, the highest concentration in chromosomalaberration test was set at lOOg g/mt with or withoutmetabolicactivation. 3. In chromosomalaberration test, the test substanceprecipitatedor floated in culturemediumat 100 g glmt 4. Data were statisticallyanalysedby the x '-testagainst the negative control. Structualaberrantcells only with gaps were excludedfrom this analysis. 6 6.
