The Spectral VEP in Normal Subjects and Dichromats

The spectral VEP in 13 normal subjects(25 eyes),four cases(8eyes)of protanopes and 8 cases(15 eyes)of deuteranopes were tested.Innormal subjects,the shortest latencies of N1,P1,N2 were in 560 nm and thegreatest amplitudes of N1-P1 and P1-N2 were in 560-570 nm,around which thelatencies were delayed and the amplitudes were decreased as the wave-lengthes of stimulative light increased or decreased gradually.The spectralVEP pattern of deuteranopes was similar to the normal subjects.In theprotanopes,the shorter latencies of N1,P1,N2 and greater amplitudes of N1-P1,P1-N2 appeared in 520-530 nm and 570 nm,forming the two-thoughs and two-peaks shapes,with the shortest latencies and the greatest amplitudes in 520-530 nm.There were statistically significant differences of amplitudes and/orlatencies in some wavelengthes between the protanopes and normals and be-tween the deuteranopes and normals.Eye Science 1992;8:126-130.

Body Mass Index,Body Height,and Subsequent Risk of Colorectal Cancer in Middle-Aged and Elderly Japanese Men and Women: Japan Public Health Center-Based Prospective Study

Objective To investigate the association of body mass index (BMI) or body height with colorectal cancer incidence in a population-based prospective study.Methods We identified 986 (626 men and 360 women) newly diagnosed cases of colorectal cancer during the 9.4-year follow-up of a cohort consisting of 102,949 (49,158 male and 53,791 female) middle-aged and elderly Japanese.Results Lower BMI groups (lower than 23) were not associated with colorectal cancer compared with the 23–24.9 BMI group. Any categories of 25–26.9, 27–29.9, or 30 or more BMI were associated with an increased risk of colorectal cancer compared with the lower than 25 BMI (RR, 1.2 for 25–26.9, 1.4 for 27–29.9, and 1.5 for 30 or more; p for trend, 0.004) in men. These associations were more evident only in invasive-type cancer analysis. BMI was not associated with the risk of colorectal cancer in women. No significant association with height was obtained for either men or women.Conclusions The association of BMI with colorectal cancer was confirmed in a Japanese population as well as Western populations. Only invasive-cancer analysis suggested that BMI was important for tumor growth and proliferation. Approximately 6.7% of colorectal cancer was attributable to a BMI of 25 or higher in middle-aged and elderly Japanese men.     

Recommendations for blood pressure measurement in humans and experimental animals. Part 2: Blood pressure measurement in experimental animals: a statement for professionals from the subcommittee of professional and public education of the American Heart Association council on high blood pressure research

In experimental animals, as in humans, techniques for measuring blood pressure (BP) have improved considerably over the past decade. In this document, we present recommendations for measuring BP in experimental animals with the goal of helping investigators select optimal methods for BP monitoring in the research laboratory. The advantages and disadvantages of various BP measurement methods are discussed and specific recommendations are provided for selecting the optimal technique depending on the study objective. Although indirect techniques that permit only sporadic measurements of BP may be suitable for some purposes, methods for directly measuring BP are generally preferred because of their ability to monitor the highly dynamic nature of BP in a comprehensive fashion. Selection of the methods to be used should ultimately be guided by the study objectives to insure that the techniques chosen are appropriate for the experimental questions being explored.
