| Origin |
HAA (NBRP No.0242) and LAA (NBRP No.0243) strains of Hatano rats were originally selected and bred from Sprague-Dawley rats for their performance in the shuttle-box task at Hatano Research Institute in 1985 (Ohta, 1995). (Jun 17, 2009) |
| Strain characteristics |
HAA rats show high-avoidance in a shuttle-box avoidance task. As compared to HAA, LAA offspring showed lower body weight, delayed eye opening, poorer performance in pivoting and negative geotaxis, and increased open-field activity (Ohta, 1998). Peak level of plasma ACTH during stress condition is significantly higher in this strain (Ohta, 1999, Asai, 2004) and is susceptible to gastric ulceration (Asai, 2006). (Jun 17, 2009) |
