The borderline hypertensive rat (BHR) is a first-generation cross between the spontaneously hypertensive rat and the normotensive Wistar-Kyoto rat. The BHR develops frank hypertension when chronically stressed or when fed a high-sodium diet. Stress-induced hypertension can be blocked by exercise. The role of the central nervous system and kidney in(More)
Forty-three male borderline hypertensive rats were subjected to either 3 days, or 4, 10, or 16 weeks of daily stress. An additional 43 animals served as unstressed, age-matched controls. At the end of study, animals were sacrificed, brains were removed, and cardiovascularly-important nuclei in the brainstem and hypothalamus were removed by micropunch.(More)
Two risk factors for cardiovascular disorders, parental history of hypertension and the Type A behavior pattern, were investigated concurrently with respect to cardiovascular reactivity to challenging situations. Sixty-four college males were given both the Structured Interview (SI) and Jenkins Activity Survey (JAS) for the Type A behavior pattern and a(More)
Blood pressure and heart rate responses of the spontaneously hypertensive rat (SHR) and the Wistar-Kyoto rat (WKY) to mild restraint and tone-shock pairings were compared during a pre-stress, aversive conditioning and post-stress period, after five previous days of exposure to the paradigm. Although SHR and WKY showed similar responses to the onset of the(More)
The purpose of this study was to assess the coronary-prone behavior pattern and physiological responses to stress in young women. Thirty-seven women, aged 18-25 yr, were tested; half were studying in nontraditional fields for women, half in traditional. Based on the Jenkins Activity Survey, women in the male-dominated fields of study were more Type A.(More)
