Plates 1-15 of the Ishihara tests for color blindness were administered to 5,580 boys and 5,405 girls in primary and secondary schools in Lagos. The difference between males and females in the frequency of total color blindness was not significant. The frequency of total color blindness among the children was 0.19%. However, the frequencies of red-green color blindness, which were 3.60% and 0.81% among the males and females, respectively, were significantly different. Deutans occurred at a...

Physical inactivity, a primary risk factor for cardiovascular disease, is more prevalent within the African-American population. Unfortunately, only a few investigators have documented the effects of exercise training studies on cardiovascular fitness in this cohort. Therefore, the purpose of this study was to examine the effects of a six-week endurance exercise training program on aerobic fitness (VO2peak) in African-American females. Twenty-five women (16 treatment, 9 controls, mean age...

The aim was to examine the effects of lysophosphatidylcholine (LPC), an amphiphilic lipid metabolite in ischemic myocardium, on intracellular pH (pH(i)) regulatory systems in guinea pig papillary muscles.In CO2/HCO(3-)-buffered Tyrode solution, pH(i), intracellular Na+ activity (aNai) and membrane potential of isolated guinea pig papillary muscles were measured using ion-selective microelectrode and conventional microelectrode. Standard ammonium prepulsing with 20 mM NH4Cl was used to...
