INTRODUCTION The objective of this study was to evaluate the toxicity of the test substance] following a single oral administration in rats. In the assessment of the toxic characteristics of a test substance, determination of acute oral toxicity is an initial step. It provides information on health hazards likely to arise from a short term exposure by the oral route in Man. The study was conducted in compliance with: . O.E.C.D. guideline No. 401, 24th February 1987. . E.C. Directive No. 92/69/E.E.C., Bi, 31st July 1992. 2. MATERIALS AND METHODS 2.1 TEST SUBSTANCE 2.1.1 Identification The test substance ised in the study was supplied by Elf Atochem S.A. The test substance was identified as follows: . name: - protocol and labelling.-! . batch number: - protocol and labelling:^ . Elf Atochem filing number.^ . description: - at r e c e i p t : |P H H I H B v * - on the test article description^ . container: one plastic flask . date of receipt: 23 August 1997 . storage conditions: at room temperature and protected from light . expiry date: August 1998. Data relating to the characterization of the test substance are documented in a test article description (presented in appendix 1) provided by the Sponsor. 'At the finalization of the study report, an analytical certificate was not available. Characterization of the test substance, which appropriately defines the tested batch, is under the responsibility of the Sponsor. 2.1.2 Formulation procedure The test substance was administered in its original form. ,, coniai" TSCftCB lCjSIpawS'','" d 'D M ''0 2.2 TEST SYSTEM 2.2.1 Animals , Species, strain: rat, Sprague-Dawley ICO: OFA-SD (IOPS Caw). Reason for this choice: rodent species generally accepted by regulatory authorities for this type of study. Breeder: Iffa Credo, 69210 L'Arbresle, France. Number and sex: one group of ten animals (five males and five females). Age/weight: on the day of treatment, the animals were approximately 6 weeks old, and had a mean body weight standard deviation of 192 6 g for the males and 144 7 g for the females. Acclimatization: at least 5 days before the beginning of the study. Identification of the animals: the animals were identified individually by earmarks or eamotches. 2.2.2 Environmental conditions During the acclimatization period and throughout the study, the conditions in the animal room were set as follows: . temperature: 21 2C . relative humidity: 30 to 70% . light/dark cycle: 12 h/12 h . ventilation: approximately 12 cycles/hour of filtered, non-recycled air. The temperature and relative humidity were under continuous control and recording. The records were checked daily and retained. In addition to these daily checks, the housing conditions and corresponding instrumentation and equipment are verified and calibrated at regular intervals. The animals were housed in polycarbonate cages (48 cm x 27 cm x 20 cm). Each cage contained four to seven animals of the same sex during the acclimatization period and five rats of the same sex during the treatment period. Each cage contained dust-free sawdust (SICSA, 94142 Alfortville, France). Bacteriological and chemical analysis of the sawdust, including the detection of possible contaminants (pesticides, heavy metals), are performed regularly by external laboratories. The results of these analyses are archived at C.I.T. 2.2.3 Food and water All the animals had free access to A04 C pelleted diet (U.A.R., 91360 Villemoisson-sur-Orge, France), except as noted in "2.3.1 Fasting of the animals". Each batch of food was analysed by the supplier for composition and contaminant levels. The diet formula is presented in appendix 1/2. Drinking water filtered by a F.G. Millipore membrane (0.22 micron) was provided ad libitum. Bacteriological and chemical analysis of the water and diet, including the detection of possible contaminants (pesticides, heavy metals and nitrosamines), are performed regularly by external laboratories. The results of these analyses are archived at C.I.T. No contaminants are known to be present in the diet, drinking water or bedding material at levels which may be expected to interfere with or prejudice the outcome of the study. contain TSCA CEfl C o m p ly SanHte3- 0no .*-*<* J i. 1V> " T? 1w 2.3 TREATMENT 2.3.1 Fasting of the animals The animals were fasted for an overnight period of approximately 18 hours before dosing, but had free access to water. Food was given back approximately 4 hours after administration of the test substance. 2.3.2 Administration o f the test substance As the test substance was anticipated to be non-toxic at 2000 mg/kg, a limit test was performed by administering 2000 mg/kg of the test substance to one group of ten animals (five males and five females). The test substance was administered in its original form taking into consideration that its density was 0.848 The administration was performed in a single dose by oral route using a stainless steel roundtipped probe (diameter: 18 G.2", Perfektum: Poffer & Sons Inc., New Hyde Park, New York 11040, U.S.A.) fitted to a 1 ml glass syringe (0.01 ml graduations, Record: Carrieri, 75005 Paris, France). The volume administered to each animal was adjusted according to body weight determined on the day of treatment. ` 2.3.3 Date of treatment and duration of the study The single administration was performed on 16 October 1997 in the morning (day 1) and was followed by a 14-day observation period until 30 October 1997 (day 15). 2.4 CLINICAL EXAMINATIONS 2.4.1 Clinical signs and mortality The animals were observed frequently during the hours following administration of the test substance, for detection of possible treatment-related clinical signs. Thereafter, observation of the animals was made at least once a day until day 15. Type, time of onset and duration of clinical signs were recorded for each animal individually. Time of death was recorded individually, in terms of the number of hours or days after dosing. 2.4.2 Body weight The animals were weighed individually just before administration of the test substance on day 1 and then on days 8 and 15. , The body weight gain of the treated animals was compared to that of C.I.T. control animals with the same initial body weight. .'Does no,tcontain TSCAC<*r CIT/Study No. 16045 T. Ilf Atochem S.A. 11 2.5 NECROPSY On day 15, all animals were killed by carbon dioxide asphyxiation and a macroscopic examination was performed. After opening the thoracic and abdominal cavities, a macroscopic examination of the main organs (digestive tract, heart, kidneys, liver, lungs, pancreas, spleen and any other organs with obvious abnormalities) was performed. In case of macroscopic lesions, organ samples were taken and preserved in 10% buffered formalin. No microscopic examination was performed. 2.6 DATA EVALUATION Evaluation of the toxicity of the test substance following a single oral administration in rats should include the relationship, if any, between the animals' exposure to the test substance and the incidence and severity of all abnormalities including behavioural and clinical abnormalities, macroscopic lesions, body weight changes, mortality and any other toxic effects. 2.7 PROTOCOL ADHERENCE The study was performed in accordance with Study Protocol No. 16045 TAR and subsequent amendments, with the following deviation from the agreed Study Protocol: - the relative humidity recorded in the animal room was sometimes outside of the target ranges specified in the protocol. This minor deviation was not considered to compromise the validity or integrity of the study. 2.8 ARCHIVING The study documentation and specimens generated during the course o f the study are archived at C.I.T., 27005 Miserey, Evreux, France, for 10 years after the end of the in vivo phase o f the study. The archived study materials include: . protocol and possible amendments, . raw data, . correspondence, . final report and possible amendments. . , _ On completion of this period, the archived study materials will be returned to the Sponsor, or may be archived at C.I.T. for a further period. linpatiYSarftf.Ooesrio'it contain TSC CBl CJLT/Study JNO. 16U4S l\ It Atochem S.A. 12 3.
