- Details on study design:
- Dose selection rationale : in the dose finding study using 5 males and 5 female rats, no toxicological changes were observed at 1000 or 300mg/kg. Therefore 1000mg/kg was selected as the highest dose, and 300 and 100mg/kg were selected with the common ratio of 3. In addition 14-day recovery test groups were provided in the highest dose group and in the control group. Allocation of animals to each work group was done by a random sampling method after grouping by body weight.

Examinations
- Observations and examinations performed and frequency:
- (1) Observation of general findingsAll animals were observed once a day for external appearance and presence of abnormal behavior. In addition, moribund condition and presence of death were observed twice a day.(2) Detailed observation of clinical signsAll animals were observed for 19 items of detail symptoms such as cognition (stereotypy, passivity, alertness), mood (face washing, vocalisation), central nervous system, excitement (tremor, clonic/tonic convulsion), posture (body posture), ataxia abnormal gait), autonomic symptom (piloerection, hypothermia, skin color,respiration rate, pupil, exophthalmos, salivation, lacrimation, urination), and abnormal behavior (for one minute/animal) according to Irwin's multiple observation method1 on the day before administration start (after allocation to groups), onceafter administration, and once a week thereafter.(3) BodyweightAll animals were weighed on the starting day of administration and twice a week thereafter using an electronic balance.(4) Food intakeFood intake per cage (2~3 animals were housed in a cage) was measured using an electronic balance and food intake per capita in a day was calculated.(5) Functional examinationFive animals each from the control group and high dose group were examined.1) Visual examinationOn the 27th day, animals were examined whether they kept a horizontal posture extending the forelimb before the tactile hairs touch a laboratory desk when the animals were approached from a high position. Evaluation criteria were decided as positive reaction: + (kept a horizontal posture before touching) and negative reaction:- (no extending of forelimb by touching the tip of nose).2) AuditoryexaminationOn the 27th day, reaction to the sound of 3KHz and 120 db was examined using an audiometer (Muromachi Kikai Co., Ltd.). Evaluation criteria were decided as positive reaction: +, and negative reaction:3) Algesimetry (Tail pinch method)On the 27th day, a reaction to pinching the tail by a forceps was examined.Evaluation criteria were decided as a positive reaction or a negative reaction.4) Grasp examinationOn the 27th day, grasp responses of forelimb and hindlimb were measured using a rat-grasp response test system (MK-S80/CM/R: Muromachi Kikai Co., Ltd.). the measurement was performed twice and mean value was recorded.5) Motor activity measurementOn the 22nd day in the treatment period motor activities for male and female were measured by automated activity monitors (Supermex: made by Muromachi machine Co., Ltd.) for 22 hours immediately after administration.Clincial Chemistry and HaematologyDay and method of sacrificeThe animals from test groups after dosing period were sacrificed on the next day of final administration, and the recovery group animals were sacrificed on the next day of recovery period completion by exsanguinations (blood sampling for hematology and blood chemistry) under pentobarbital anesthesia (30 mg/kg).Method of blood samplingThe animals were fasted overnight and supplied with water only. Abdominal incision was made in the animals under pentobarbital anesthesia, and a blood-sampling needle with silicone tube was inserted into the abdominal aorta. The blood flown out naturally was collected. A certain amount of blood was sampled first for coagulation test and hematology, and then sampled for blood chemistry. The blood samples were left untreated for about 50 to 60 minutes in room temperature, and then serum was obtained by centrifugation (5000rpm/min, 10 min) after confirming blood coagulation.The blood sampling was conducted on one animal each from the control group, low dose group, intermediate dose group, and high dose group in this order first, and then reverse order from the high dose group to the control group next. This process was repeated on male first and then conducted on female.The anticoagulant, 3.2 % sodium citrate solution was used for the examination of coagulation system, and EDTA-2K for the other hematology.
- Sacrifice and pathology:
- The following items were examined after sacrifice by exsanguinations.1) NecropsyAll animals were observed macroscopically for body surface, orifices, cranial cavity,organs in thoracic and abdominal cavities, and lymph nodes.2) Organ weightThe brain, pituitary, heart, liver, kidneys, thymus, spleen, adrenals, testes, epididymides, prostate, seminal vesicles, ovaries and uterus from all animals were weighed (absolute) with electronic balance (AEX-200B: Shimadzu Corporation), and organ/bodyweight ratio (relative organ weight) was calculated based on the body weight at necropsy. The kidneys, adrenals, testes or ovaries, and epididymides were weighed right and left organs together. The prostate, seminal vesicle and uterus were weighed on the next day.3) Histopathological examinationThe heart, liver, kidneys, adrenals, spleen, testes, epididymides, prostate, seminal vesicles, ovaries and uterus from the control group and high dose group at the end of administration period and the liver and kidneys from the recovery groups were routinely prepared as paraffin sections and stained with H • E staining for microscopic examination. In addition, the kidneys, testes, and epididymides were stained with PAS reaction and examined microscopically. Evaluation criteria for pathological lesions were indicated as minimal: ±, slight: +, moderate: ++ and severe: +++.
- Other examinations:
- In addition, the organs remained after supplying for the examination described above and the brain, pituitary, eyeball and Harderian gland, salivary gland (submaxillary gland, parotid gland), esophagus, trachea, thyroid (including parathyroid), lung, thymus, heart, stomach and duodenum, small intestine, large intestine, pancreas, adrenals, kidneys, urinary bladder, testes, prostate,epididymides, seminal vesicle, coagulation gland, ovaries, uterus, bone marrow(femur), peripheral nerves, lymph node (mesenteric lymph node) and skin were fixed and preserved in neutral phosphate buffered 10 % formalin. In addition, the testes and epididymides were fixed in Bouin's solution and preserved in neutral buffered 10% formalin
- Statistics:
- Data obtained by each examination were assessed by Bartlet test for homogeneity of variance with multiple comparison method. Where variances were shown to be homogenous one-way analysis of variance was conducted and followed by Dunnet multiple comparison test when significant differences were recognised. Where the test showed unequal variances Kruskal-Wallis rank sum test was conducted and followed by Dunnett's rank test when significant differences were found. However, statistical analysis was not conducted on the data of general condition, detail observation of signs, function test, necropsy and histopathology.

- Executive summary:
Introduction.
The study was designed to investigate the systemic toxicity of the test material and was performed in compliance with the standards stipulated in the GLP of Japanese Chemical Substances Control Law "Testing facilities in conducting tests stipulated in article 4 of the Order Prescribing Those Items of the Test Relating to the New Chemical Substances and Study on Harmful Effects of Designated Chemical Substances". (Kanpoan No.41, March 1, 2000, Japanese Ministry of the Environment, Integrated Environmental Policy Bureau, Seieihatu No. 268, the Japanese Ministry of the Health, Labour and Welfare, Medical Safety Bureau, Kikyoku No.1, the Japanese Ministry of Economy,Trade and Industry, Manufacturing Industries Bureau Joint Notification) and Guideline of Japanese Chemical Substance Control Law " Methods for the Test on New Chemical Substances" Partial Amendment and Others (Kanpogyo No. 700, December 5, 1986, Japanese Ministry of the Environment, Integrated Environmental Policy Bureau, Yakuhatsu No. 1039, the Japanese Ministry of the Health, Labour and Welfare, Medical Safety Bureau, Kikyoku No. 1014, 1986, the Japanese Ministry of Economy, Trade and Industry, Manufacturing Industries Bureau, Notification).
Method
Test material at 1000 mg/kg bw/day (high dose group), 300 mg/kg bw/day (intermediate dose group) or 100 mg/kg bw /day (low dose group) or purified water used as vehicle was administered. In addition, 5 males and 5 females each from the high dose group and the control group were allocated to recovery test groups.
Results
There were no deaths on the study and no changes attributable to the influence of test material were detected in any dose group. Blue staining similar in colour to the test material was seen in feces and urine as well as alimentary tract contents and renal cortex at necropsy. This change was judged not to be toxicity effect.
Conclusion
The NOEL was concluded to be 1000mg/kg/day in both male and female rats
