Results The Cronbach’sα coefficient of the general item of MMPI is 0.94, each scale is 0.71～0.87. In validity scale F of schizophrenes is obviously higher than that of healthy recruits, and L,K is less.
Methods The heart rate variability (HRV) was analyzed and the baroreflex sensitivity (BRS) was evaluated in 14 civil flying personnel with hypertension and 14 age matched healthy subjects using conventional AR spectral analysis and sequential analysis respectively.
Methods The study population consisted of 118 pilots and 96 healthy subjects as controls. The genotypes for an I/D polymorphism in intron 16 of the ACE gene were determined by the polymerase chain reaction (PCR).
Methods:Eight healthy volunteers were given a single dose of amikacin 5 mg/kg im under 3different conditions in succession:Ⅰ. without HBO treatmentⅡ. a week later,right before 0.25MPa(2. 5 ATA) HBO 1h treatment;
In order to study the characteristics of human body dynamic responses to impact acceleration during manned spacecraft landing, 5 healthy young men were exposed to 4～10 g for 50～80ms halfsine acceleration pulse in 20° supine angle and 10 g for 50ms halfsine acceleration pulse in 30°～60° supine angle.
Study subjects were divided into three groups: subjects in group 1 were microalbuminuric diabetic (n = 33), in group 2 subjects were normoalbuminuric diabetic group (n = 32), and group 3 was formed from nondiabetic healthy control subjects (n = 18).
As both P and Q are constant for a healthy motor, they are represented by a dot on the PQ plane.
In the dry year (2002), for several months, soil water content of potted trees was lower than its threshold value for non-available soil water content, which could influence the healthy growth of trees.
Genomic DNA was extracted from blood samples of healthy controls and from patients with HBV infection.
Eight young, healthy male volunteers were exposed to two 24 h periods of continuous wakefulness during the crossover experiment.
