| Abstract: | "Two male adult rhesus monkeys were used and caged individually. The room was temperature-controlled having a light-dark period of 12/12 hours. The animals were rapidly immobilized and immediately anesthetized with ketamine i. m. (10 mg/kg of body weight). They were bled four times at 15, 30, 45 and 60 mins after the ketamine injection, twice a week for 6 weeks. When necessary, maintenance doses of ketamine were administered. The serum levels of cortisol and prolactin after nasal instillation of a suspension of vaginal exudate showed lower values than in control conditions (nasal instillation of saline). The control levels of cortisol tended to increase up to 60 mins, whilst in experimental conditions (nasal instillation of female urine or vaginal exudate) did not show such an increase. Cortisol remained similar during the sampling and similar to the 15 mins control levels, but the difference is statistically significant only after instillation of vaginal exudate as compared with control. The levels of prolactin did not show significant variations during sampling either in control or after female urine instillation. However, the instillation of vaginal exudate decreased the prolactin levels at 15 mins which tended to recover the control levels up to 60 mins. These results support the hypothesis, discussed in a previous paper, that some chemical information from females suppresses or mitigates the effect of acute stress resulting from handling the animals before anesthesia" |
