- CLINICAL SIGNS AND MORTALITY
Four rats from the high dose group died during the sixth week. The level was subsequently lowered to 4.00 g/kg/day for the remaining seven weeks.
BODY WEIGHT AND WEIGHT GAIN
The male control group gained an average of 397.8 g during the course of the experiment, the 0.50 g/kg/day group gained an average of 321.9 g, the 2.00 g/kg/day group gained an average of 207.9 g and the 8.00g/kg/day-4.00 g/kg/day group (three survivors) gained an average of 134.2 g. The female control group gained an average of 166.6 g, the 0.50 g/kg/day group gained an average of 155.3 g, the 2.00 g/kg/day group gained an average of 113.1 g while the 8.00g/kg/day-4.00 g/kg/day group (six survivors) gained an average of 93.8 g.
From the above data it becomes obvious that Aerosol 18 depresses significantly the rate of body weight gain in the rats of all levels under the conditions of this experiment. This depression appears more pronounced in the male than in the female rats.
FOOD CONSUMPTION AND COMPOUND INTAKE (if feeding study)
The mean feed consumption data in g/rat/week for the male control group was 178.4 g, for the 0.50 g/kg/day group 171.5 g, for the 2.00 g/kg/day group 159.9g and for the 8.00g/kg/day-4.00 g/kg/day group (three survivors) 144.0 g. The corresponding mean feed consumption for the female control group was 144.3 g, for the 0.50 g/kg/day group 147.1 g, for the 2.00 g/kg/day group 147.5 g and for the 8.00g/kg/day-4.00 g/kg/day group (six survivors) 141.1 g.
During different weeks the feed consumption of the test animals was significantly depressed more so in the male rats than in the female rats.
FOOD EFFICIENCY
The mean feed efficiency (change in body weight (g)/ feed(g)/rat/week) for the male control group was 0.18, for the 0.50 g/kg/day group 0.15, for the 2.00 g/kg/day group 0.10 and for the 8.00g/kg/day-4.00 g/kg/day group (three survivors) 0.07. The corresponding feed efficiency for the female control group was 0.09, for the 0.50 g/kg/day group 0.08, for the 2.00 g/kg/day group 0.06 and for the 8.00g/kg/day-4.00 g/kg/day group (six survivors) 0.06.
The feed efficiency of the male mid dose and male high dose test groups is decidedly different from that of the male control group. The female groups, however, do not differ from the female control group to the same extent as the male test groups.
HAEMATOLOGY
A. Hematocrit
All rats had normal hematocrit concentrations for the duration of the experiment.
B. Hemoglobin
All rats had normal hemoglobin concentration for the duration of the experiment except for rats #4927, #4935 and #4930 (8.00g/kg/day-4.00 g/kg/day group) which had hemoglobin values of 18.1, 18.3 and 18.1 g%, respectively at six weeks. Rat #4935 had a normal hemoglobin at three months; rat #4927 died of acute, toxic cystitis and rat #4930 died of toxic gastritis before three month data could be taken.
C. White Blood Cell Count
Rats #4891 and #4910 (2.00 g/kg/day group) at six weeks had WBC counts of 36600 and 30900 cells/mL, respectively, but by three months their WBC was normal. Rat #4827 (control group) at six weeks had a WBC of 27800 cells/mLand 25100 cells/mL at three months, but its bone marrow was histologically normal.
D. Differential White Blood Cell Count
The albino rat in our experience displays lymphocytosis normally throughout its lifetime. All rats examined at six and 13 weeks displayed lymphocytosis.
E. RBC Morphology
The RBC’s of all animals were morphologically normal at all time.
CLINICAL CHEMISTRY
A. Blood Glucose
All rats had normal blood glucose values.
B. Blood Urea Nitrogen
All rats examined had normal BUN values.
C. Serum Glutamic Oxaloacetic Transaminase
Female rats #4924, #4940 and #4946 (8.00g/kg/day-4.00 g/kg/day group) had SGOT values at three months of 200, 230 and 250 units/liter, respectively.
D. Serum Glutamic Pyruvic Transaminase
Rats #4924, #4940 and #4946 (8.00g/kg/day-4.00 g/kg/day group) has SGPT values at three months of 112, 125 and 140 units/liter, respectively.
E. Gamma Glutamyl Transpeptidase
All rats examined had normal GGTP values.
URINALYSIS
Some of the rats in all groups displayed hematuria to a greater or lesser degree. Of the animals which were sacrificed at the end of the study, rat #4855 (0.50 g/kg/day group) displayed chronic renal disease, usually seen in this strain of rat but at a later age. The urinary system of the other sacrificed rats which displayed hematuria was not remarkable histologically.
ORGAN WEIGHTS
The weight of the parenchymal organs (heart, liver and kidneys) of the mid dose and high dose male rats and the mid dose group of female rats, are significantly lower than the corresponding weight of the relevant control groups. The heart and kidneys of the high dose female rats are also significantly lower. This parallels the decrease in mean body weight of these same groups. In addition, there is a significant decrease in the mean thyroid weight in the mid dose and high dose rats and in the mean adrenal weight of the mid dose and high dose male groups as well as of all female test groups. Finally there is a significant decrease in the mean ovarian weight of the mid dose and high dose group.
GROSS PATHOLOGY
Zonal fatty infiltration of the liver in het high dosed males and females.
HISTOPATHOLOGY: NON-NEOPLASTIC : The 8.00 g/kg/day rats which died halfway through the experiment displayed classical acute toxic findings of the gastrointestinal and urinary system as described in the appropriate necropsy reports. Some of the high dose test rats which were sacrificed at the end of the experiment displayed zonal fatty infiltration of the liver. The rest of the examined rats from the terminal sacrifice displayed normal histology.

Applicant's summary and conclusion
- Conclusions:
- From the data presented in this study it appears that the NOEL for Aerosol 18 in the rat is < 500 mg active ingredient/kg feed/day when orally administered; NOAEL is considered 500 mg/kg bw/day.
- Executive summary:
The purpose of this study was to investigate the toxic effects, if any, of test item containing 35% active ingredient when fed to albino rats for ninety days at doses of 0.50, 2.00 and 8.00 g act.ingr./kg bw/day. The rats were carefully observed for the duration of the experiment, body weight and feed intake /conversion were measured and pertinent haematological and biochemical parameters were conducted after 6 weeks and after termination. At the conclusion of the experiment all rats were necropsied and all organs and/or tissues were examined histologically from ten rats (five male and five female). Due to mortality of 4 rats at 8 g/kg bw/day, dosing was reduced to 4 g/kg feed/day after 6 weeks. The study further showed decreased body weight gain and food intake at all levels and acute gastro-enteritis and/or acute nephritis within six weeks at 8.00 g/kg/day. When this dose was decreased to 4.00 g/kg/day and given for seven weeks some rats displayed zonal fatty infiltration in the liver. At the lowest dose level, decreases in body weight (gain) and feed intake were minimal (<10%), and were not considered relevant. Decreased organ weights were observed for heart, liver, kidneys, adrenal an thyroid weight at the medium and high doses. From the data presented in this study it appears that the NOEL was < 500 mg act. ingr./kg bw/day, however the NOAEL can be considered to be 500 mg/kg bw/day.
