Abstract
Shin Nippon Biomedical Laboratories, Ltd. (SNBL) imported and quarantined 3,148 cynomolgus monkeys (aged 2.5 to 6.5 years) from China in 2002. The hematology and blood biochemistry data obtained from these monkeys on Day 32 of quarantine were analyzed separately by sex [2,890 animals in which no abnormalities were observed during the 35-day quarantine period (normal group), and 258 animals which exhibited diarrhea 1 to 12 times (diarrhea group)]. The values obtained for all parameters were within the normal range (mean ± SD), and no significant abnormalities were noted in either sex. The clinical pathology data from 11 animals (6 males and 5 females) exhibiting diarrhea repeatedly (10 to 12 times) were statistically analyzed, and significant differences were noted in PLT and ALP in both sexes. The PLT values of these animals were within the normal group mean ± 2 SD, and were considered within the normal range. A significant difference was noted in some individual ALP values (males: Nos. 2 and 3, females: Nos. 1, 3, and 4). The clinical pathology data obtained from the normal group in this study basically correspond to the widely reported results already obtained from healthy cynomolgus monkeys, from which it can be concluded that the cynomolgus monkeys from China were generally healthy and presenting no particular abnormality. The clinical pathology data from the normal group will serve as valuable baseline data for experimenters using cynomolgus monkeys.
