Spontaneously hypertensive Wistar-derived male rats are more aggressive than those of their normotensive progenitor strain.

摘要: We compared a group of spontaneously hypertensive rats (SHRs) to Wistar-Kyoto (WKY) on each the three most commonly studied forms aggressive behavior in rats: muricide, intraspecific aggression, and shock-induced fighting (SIF). A significantly higher proportion SHRs were muricidal; they also fought more at lowest shock level. trend for incidence offense behaviors by was not significant. SHR flinch jump thresholds lower than respective WKY thresholds. Although there no significant correlations between any aspects SIF, possibility that strain differences sensitivity may contribute SIF cannot be ruled out. Within strains, among different aggression. Several inherited characteristics associated with accentuation aggression SHRs.
