  Abstract:  Background. Hypothermia is a stressful agent used in order to induce experimental laboratory stress. Aims. The study evaluated the effects of acute hypothermic stress (5° C) on spontaneous motility and emotivity of the rats with and without carnitine supplementation. Methods. The study was made on four groups of male adult Wistar rats (n=10 animals/group) for 3 days long: group I – control, group II – exposed to hypothermic stress, group III – supplemented with carnitine, group IV – supplemented with carnitine and exposed to hypothermic stress. Spontaneous motility (movements and rearings) and emotivity (micturitions and defecations) were evaluated by Open Field Test. Results. The hypothermic stress determines significant decreases of the spontaneous motility and significant increases of the emotivity; carnitine supplementation in acute hypotheremic stress exposed animals induces significant spontaneous motility decrease and significant emotivity increase as compared to the control animals. Conclusions. Acute hypothermic stress with and without carnitine supplementation induces hypomotility and hiperemotivity. Carnitine does not improve the spontaneous motility, but induces significant decreases of the emotivity in acute hypothermical conditions.
