RM-Freetext:
dosage males: 55.4; 228.0; 985.2 mg/kg b.w./day
(calculated)
dosage females: 68.7; 282.6; 1488.5 mg/kg b.w./day
(calculated)
no death, no effect on behaviour, reduced body weight gain, increased feed
(females) and water consumption (males) at the high dose level, absolute and
relative liver weight is significantly dose-related increased at all dose
levels, kidney weight only increased at the high dose level, no
substance-related histopathological effects (47 organs and tissue),
opthalmological, hematological and clinical- chemical parameters within the
normal range, slightly increased tromboplastin/time at the high dose.
Applicant's summary and conclusion
- Executive summary:
In a subchronical 3 month-feeding study male and female rats received the test substance via food in following doses: 0 (control-group); 750; 3000; 12000 ppm.
No mortalities and no effects on behaviour were observed.
Food and water intake were not modified up to 3000 ppm. In the highest dose group of 12000 ppm the female rats consumed more food and the male rats had an increased water consume.
The growth was delayed in male and femal rats in the highest dose group.
The absolute and relative liver weight was significantly dose-related increased at all dose levels, but the kidney weight only increased at the high dose level. No substance related histopatological effects (aorta, eyes with lids, cecum, duodenum, femur, brain, bladder, testicles, skin, heart, pituitary gland, larynx, head, ileum, jejunum, liver, lung, mesenterial lymph node, mandibular lymph node, stomach, lactiferous gland, spleen, femoral musculature, epididymis, nervus ischiadicus, nervus opticus, kidneys, esophagus, ovaries, oviduct, pancreas, prostata, rectum, cervical, thoracal and lumbal spinal cord, seminal vesicle, thyroid gland, salivary gland, sternum, thymus (if present), trachea, extraorbitary lacrimal gland, uterus, vagina, tongue) were observed.
Ophtalmological, hematological and clinical parameters were within the normal range.
Only a slightly increased tromboplastin-time was observed in male rats at 12000 ppm.
The NOAEL for male and female rats therefore is 3000 ppm.
