Item Contributions of Dietary Protein and Zinc Deficiencies to Protein Energy Malnutrition(Ghana Medical Journal, 1990-03) Asibey-Berko, E.Some degree of zinc deficiency seems present in all cases of Protein-Energy malnutrition. Protein Energy Malnutrition (PEM) was induced in male Wister rats fed either adequate (30ppm) or moderately deficient levels of zinc (6ppm) in diets containing either 0.4 01' 20% spray-dried egg white. The protein-deficient rats developed PEM with oedema in 4 - 5 weeks regardless of their dietary zinc level. Except for disorders of the brain, protein deficiency was the major cause of most PEM signs - loss of appetite, growth failure, oedema, water accumulation in the liver, hypalbuminaemia and mortality. Dietary zinc deficiency aggravated some of these to a small extent. Dietary zinc alone accounted for elevations of brain iron and sodium in both PEM and non PEM rats. This suggests that zinc deficiency may significantly contribute to some of the symptoms of PEM.Item Importance of Bulinus Globosus Snails in the Transmission of Urinary Schistosomiasis in Eight Villages in Southern Ghana.(Ghana Medical Journal, 1999-06) Aryeetey, M.E.; Wagatsuma, Y.; Yeboah, G.K.; Asante, M.; Mensah, G.; Kojima, S.Snail survey was carried OUI al water contact siles (WCSs) of 8 villages in southern Ghana 10 establish freshwater snails responsible for schistosomiasis transmission in the area. Bulinus globosus, one of the intermediate host snails of Schistosoma haematobium was found at the WCSs in all 8 villages although those infected were identified at sites in 5 of the villages. The snails were confined to the Densu river itself, its tributaries (streams) and ponds. These snails were found during the minor rainy season. at the beginning of and during the dry season. They were found to be focal in distribution. Also found in the Densu river and the ponds were uninfected Biomphalaria pfeifferi snails. In addition to those indicated above, non·schistosome transmitting snails were also found.
