RESUMO
Protein-energy malnutrition is one of the major public health problems in developing countries of the world due to prevailing socio-economic problems. This study aimed to observe the effect of formulated complementary blends on biochemical parameters of rats. Extruded complementary blends from maize fortified with cowpea or soybean at a level of 35% and 25% respectively were fed to 4 groups of rats for 28 days. Similarly, 3 other groups of rats were placed on casein, non-protein or rat pellet diet. Biochemical analysis was done on blood samples of the rats. Results from previous studies show the protein content of the formulated diets to range from 15.75% in UMC to 17.24% in MMS. Significantly (p < 0.05) lower WBC, Hb, MCHC, total protein, albumin and globulin values were recorded for the rats fed a non-protein diet (NP). The serum AST level was 75.5, 71.2, 63.2, 51.0, 60.5 and 55.7, respectively, for rats on casein, rat pellet, MMS, UMS, MMC and UMC (list of abbreviations is shown in the appendix) diets. Alkaline phosphatase was significantly (p < 0.05) higher in soybean-based diets while cholesterol was lowest in rats fed the non-protein diet (NP). The value obtained for serum electrolyte concentration in the rats fed NP compared well with rats on other diets but, however, had a significantly (p < 0.05) higher serum sodium value. These results confirm that the experimental diets supported growth, as shown in a previous study, and had no harmful consequence.

The effectiveness of rice flour and maize flour based oral rehydration solution (ORS) in treating mild and moderate dehydration was studied among 88 children aged to 6 to 42 months at the Oni Memorial Children Hospital, Ibadan. In this randomized clinical trial, fifty children were treated with rice-based ORS while fifty-three received the maize-based ORS, over a four hour period. There was clinical improvement in the signs of dehydration with a significant increase in body weights and a significant fall in the packed cell volume following the administration of the two preparations. The maize-ORS contains 4.3 g protein, 179.3 Kilocalories and rice-ORS contains 3.6 g protein and 152.1 Kilocalories per litre of the preparation, respectively. It is concluded that rice and maize based ORS were acceptable and effective in oral rehydration of diarrhoea patients. They may also contribute to the nutrient intake of patients with (mild to moderate) 'some' dehydration. However other sources of energy, protein and mineral intake should be continued in these patients.
