Table 1: Calculation and Results
Vehicle: acetone:olive oil (4+1 v/v)
Test item concentration % (w/w)
number of lymph nodes
DPM per lymph nodeb)
BG = Background (1 ml 5% trichloroacetic acid) in duplicate
1 = Control Group
2-4= Test Group
S.I. = Stimulation Index
a) = The mean value was taken from the
figures BG I and BG II
b) = Since the lymph nodes of the
animals of a dose group were pooled, DPM/node was determined by dividing
the measured value by the number of lymph nodes pooled
EC3 value could not be calculated, since all S.I.´s are below the
threshold value of 3.
The sensitization potential was investigated according to OECD Guideline
The test item concentrations chosen for the LLNA test were 2.5, 5,
No deaths occurred during the study period. No systemic or local
findings were observed during the study period. The body weight of the
animals was within the range commonly recorded for animals of this
strain and age.
