Patterns of social desirability and anger in young men with a parental history of hypertension: association with cardiovascular activity.

We identified, via cluster analysis, subgroups of young men with a parental history of hypertension (PH+) who differed in their profiles of need for approval, covert experience of anger, and extent to which they express anger when provoked. The PH+ subgroup with high need for approval and low anger acknowledgment scored higher on denial but lower on measures of angry temperament and overt display of anger than did the PH+ subgroup with low need for approval and high anger acknowledgment or men without a parental history of hypertension (PH-). Moreover, the PH+ subgroup with high need for approval and low anger acknowledgment manifested significantly higher stressor-induced blood pressure (BP) responsivity than did the other two groups. Possible relations between parental history status, need for approval, anger, BP reactivity, and essential hypertension are discussed.

Automated computerized rat eater meter: description and application.

A real-time Automated Computerized Rat Eater Meter was developed by modifying commercially available metabolic cages. Food access via a feeding tunnel was monitored by photocells. Food consumption was measured by an electronic scale. The signals thus generated were processed by a computer. This allowed us to continuously measure the spontaneous feeding behavior of free-feeding nondeprived Fischer rats for a sum total of 35 study days. Based on our data, we defined a meal as an episode of food consumption preceded and followed by at least 5 minutes of no feeding. Fischer rats showed periodic nychthemeral eating behavior. Food consumption, number of meals, meal sniffs, intermeal sniffs, and, consequently, eating activity were greater during the dark cycle than the light cycle. Meal duration, meal size, and thus food consumption rates remained constant throughout both cycles. Our modification of commercially available metabolic cages provides unique data for continuously monitoring rat feeding patterns over prolonged periods of time.
