Background: Ergonomic furniture design which is based on the application of the anthropometric measurements of the intended users does not only reduce the risk of developing musculoskeletal disorders such as low back pain, but also improves work performance. Aim: The main aim of this study was to survey and describe Nigerian University students based on important anthropometric measures relevant to ergonomic classroom furniture design. Method: A total of fi ve hundred and ninety (undergraduate and graduate) students where surveyed using the traditional methods of data capture. The measurement considered were the most important anthropometric features relevant to ergonomic furniture design. Result: The result of the survey was stratifi ed according to gender and age. Across all age groups, males had higher mean values for anthropometric measurement except for the hip width which was found to be higher in females than in males. When the participants were considered broadly as just males and females without consideration for their age groups, sexual dimorphism was seen to still exist. The males had higher mean values for all the anthropometric measurement except for hip width (males = 30.7±2.7cm; females = 33.9±3.7cm). Dimensions for ergonomic furniture design for the study population was also determined and presented. Conclusion: The study anthropometrically describes young Nigerians and therefore provides data which can be deployed by furniture designers for ergonomic product manufacture.

Background: Cadmium (Cd) has been reported to cause distinct neurotoxic effects in adult and newborn animals. This study was designed to investigate some of the effects caused by cadmium on the lateral geniculate body of adult male wistar rats and the ameliorative properties of antioxidants present in Moringa oleifera seed oil and walnut oil extracts. Methods: Seven groups of fi ve animals each were used in this experiment. Group A received 3 ml of 0.9% normal saline; group B received 2.5 mg/kg bw of 3CdSO 4 .8H 2 O, group C received 5 mg/kg bw vitamin C & 6 mg/kg bw vitamin E, group D received 5 mg/kg bw vitamin C & 6cmg/kg bw vitamin E + 2.5mg/kg bw Cd, group E received 2.5 mg/kg bw Cd + 4 mg/kg bw Moringa oleifera Oil, group F received 2.5 mg/kg bw Cd + 4 mg/kg bw walnut oil, while group G received 2.5 mg/kg bw Cd + 2 mg/kg bw walnut + 2 mg/kg bw Moringa oleifera oil concomitantly for 3 weeks, histomorphological investigations were carried out in the brain tissues. Results: Light microscopy examination revealed marked changes in the structure of the studied tissues of Cd administered animals. However, administration of vitamin C & E, walnut and Moringa oleifera seed oil was seen to counteract the changes of the measured parameters and restore the damaged tissues associated with Cd administration to appear nearly like those of the control group A. Conclusion: Walnut and Moringa oleifera seed oil administration attenuated morphological changes induced by cadmium in the lateral geniculate body of the brain of the adult male wistar rats.
