Purpose: Caffeine is widely consumed as kola nuts and in other products in sub Saharan Africa.
We examined the acute effect of caffeine on the intraocular pressures of healthy Nigerian volunteers between the ages of 20 and 27 years.
Methods: Intraocular pressure and blood pressure were measured 0, 30, 60, and 90 minutes after the ingestion of coffee by two groups of participants, namely the ex perimental (caffeinated coffee) and control (decaffeinated coffee) groups.

Since calcium and magnesium are essential to the body’s needs, their input and output are generally balanced by their dietary intake and their loss through the excretory organs. This study investigated the concentrations of calcium and magnesium in the sweat excreted from normal Nigerian men sweating under raised temperature or during exercise heat and exercise conditions.

The study examined the role of peers and parental influence on career choice in medicine. One research hypothesis was formulated to guide the study. Three research instruments were used; they are: the students occupational clusters preference scale (OCPS), peer pressure assessment scale (PPAS) and the parental influence assessment inventory (PIAI). Two private and two public schools were randomly selected for the study. Twenty-five respondents were randomly selected from each of the schools giving a total of a hundred respondents. Data were recorded or collected from each respondent.

Cataract is the most common cause of curable blindness in Nigeria1, 2. Nigeria has an overall population of approximately 110 million with a blindness prevalence rate of 1%. Cataract is responsible for 30 – 60% of the blindness1, 2. A great deal of blindness prevention activity should therefore centre around cataract surgery if we are to clear out cataract back log of over ½ individuals. Only 106 cataract surgeries were performed in the 24 months reviewed.

The unipolar Heamiarthroplasty designs introduced by Thompson and Moore, have been the popular choice for femoral neck fractures in elderly patients. Some implant related complications were observed to be more severe or accentuated in the more active and mobile elderly. The introduction of the Bipolar type was meant to reduce such complications. Presented is a 5 year report on our experience with the bipolar implant at the University of Benin Teaching Hospital (UBTH).

For more than two decades, the Republic of Chad has been caught up in a complicated tangle of domestic problems which worsened from day to day. This apparently overwhelming series of crises was encouraged and complemented by external forces, and made the solution to the country’s problems more difficult to achieve.

Different methods of storing coconut were examined to determine their effects on changes in nut water and endosperm. The first preliminary experiment was carried out for 72 days and the second for 8 months. The results showed that the nuts generally dried up (without liquid endosperm) after 5 months of storage but those stored in bags and watered, retained liquid endosperm for 6 months.

For many decades, sociological perspectives dominated learning in science education. Recently, a shift has occurred from science for specific social purposes, situated cognition to anthropological perspective that contextualizes science learning in cultural milieu. Such anthropological perspectives view science and science education as cultural enterprise, which form parts of the wider cultural matrix of society.

Seed of Leucaena leucocephala were analyzed to determine the oil content and physiochemical characteristics of the oil. The results obtained are compared with the characteristics of known oils. The iodine value of the oil (107 – 158) and saponification value in the range of 231 – 273mg KOH compared closely with those of known drying oils of high unsaturation level with potentials for the preparation of soap and the formulation of surface coating. The peroxide value and acid values show close comparison with the refractive index (1.468).
