Sixty-five women (aged 32 - 54 yrs) were assessed at 2 months before to 8 months after total abdominal hysterectomy on four separate occasions. Beck's Depression Inventory (BDI), Taylor's Manifest Anxiety Scale (TMAS), the Buss-Durkee Hostility Inventory (BDHI), Measurement of Masculinity-Femininity (MF), Likert scales and semantic differentials for psychological, somatic and sexual factors varied as assessment tools. High-dysphoric and low-dysphoric women were compared with regard to hysterectomy outcomes. Married nulliparae suffered from enhanced depression post-surgery. Pre-surgery anxiety, back pain and lack of dyspareunia contributed to post-surgery anxiety. Pre-surgery anxiety was related to life crises. Pre- and post-surgery hostility occurred in conjunction with poor sexual gratification. Post-hysterectomy health improved, but quality of sexual relationship was impaired. Partner support and knowledge counteracted hysterectomy aftermath. Post-hysterectomy symptoms constituted a continuum to pre-surgery signs of depression, anxiety or hostility.

In 2 experiments, the authors examined 69 mice selectively bred for high or low levels of open-field (OF) thigmotactic behavior (high open-field thigmotaxis [HOFT] and low open-field thigmotaxis [LOFT], respectively). They found that the strains differed in defecation during the 60-min exposure to the OF. Furthermore, the strains differed with regard to their life spans: The more thigmotactic HOFT mice lived longer than the LOFT mice. The strains were not differentiated by food intake or excretion. The strain difference in thigmotaxis was not age dependent, and it persisted in the home-cage condition as well. Neither the location (center or wall) of the starting point nor the shape (circular or square) of the OF arena affected the difference in wall-seeking behavior between the two strains. The authors concluded that the difference in thigmotaxis (or emotionality) between the HOFT and LOFT mice is a stable and robust feature of these animals.

The present study assessed the life spans in two lines of mice selectively bred for high (Turku Aggressive, TA) and low (Turku Nonaggressive, TNA) levels of aggression. The maintained parental Swiss albino strain (N), normally distributed with regard to aggression, served as a control line. It was found that the TNA males had a significantly shorter life span than the other lines of mice of both sexes. The relative early death of the TNA males was discussed in terms of male age‐related decline of inherited low levels of catecholamine and androgenous hormone concentrations. © 1996 Wiley‐Liss, Inc.

The main purpose of this research was to investigate whether the difference in open-field (OF) thigmotaxis between mice selectively bred for high and low levels of wall-seeking behavior originated from genetic or acquired sources. Unfostered, infostered, and crossfostered mice were compared in two experiments in which the effects of strain, sex, and fostering on ambulation, defecation, exploration, grooming, latency to move, radial latency, rearing, thigmotaxis, and urination were studied. These experiments revealed that OF thigmotaxis was unaffected by the foster condition and thus genetically determined. The selected strains of mice also diverged repeatedly with regard to exploration and rearing. The findings are in line with the previously described existence of an inverse relationship between emotionality and exploration.
