The role of social experience in the production of gastric ulcers in hooded rats placed in a conflict situation.

Abstract: 40 male hooded rats were used in an investigation concerning the relation of social experience to ulcer formation in a long-term approach-avoidance conflict situation. The hypotheses were: "1. Animals placed in the conflict situation alone are less resistant to ulceration than animals tested with other animals present. 2. Animals reared in isolation are less resistant to ulceration than animals reared together. 3. Interaction effects between these 2 sets of conditions exist." The first hypothesis was confirmed… Show more

“…Similarly, in both monogamous prairie voles as well as non-human primates, stress responses (corticosterone/cortisol) to a novel environment were reduced when accompanied by a con-specific (30,31). Linking the presence of familiar others with health-related outcomes, the efficacy with which unexpected electric shock led to peptic ulcers in rats was shown to be due, in large part, to whether the rats were shocked in isolation (high ulcer rates) or in the presence of littermates (low ulcer rates) (32). Moreover, social crowding led to hypertension in mice, but only when mice were placed with strangers, not when they were placed with littermates (33).…”

“…One manifestation of this is the organism's characteristic response to separation as a physiologic stressor 42–44 and social bonding as its salutary antithesis 45,46 . In nonhuman social animals these effects occur whether the bonds are those of a sexual pair, 41 parent‐offspring, 47 littermates, 48,49 or social companions 32 . Evidence from the experience of humans with separation and reunion suggests that we experience similar physiologic interdependence 50,51 .…”

“…Furthermore, the susceptibility to such ulcers appears to be influenced by such variables as the social interactions among these animals. 3 Bonfils and his associates 2 ' a have produced gastric ulcers in a high percentage of Wistar rats following approximately 20 hours of physical immobilization together with food and water deprivation. The lesions resulting from this procedure were located in the body of the stomach, which is the glandular, acid-secreting, lower portion.…”
