Protein was determined by the macro-Kjeldahl procedure and lysine by a microbiological technique described earlier (3). The protein content was 9.2% and the concentration of lysine was 4.25 g/100 g protein. Maize was given in the form of chapati (unleavened bread) or porridge. In addition, all the children received one multivitamin tablet (vitamin A, 2,000 IU; vitamin D, 200 IU; thiamin, 1 mg; riboflavin, 1.2 mg; ascorbic acid, 30 mg) and one fersolate tablet (60 mg iron) per day. A daily record of clinical progress and body weight was maintained. Blood samples were obtained at the time of admission and again on the 10th and 30th days of treatment. Hemoglobin was determined as oxyhemoglobin and serum albumin was estimated by the micro-Kjeldahl method after fractionating with 28% sodium sulfite. Criteria employed in the assessment of response are 1) time taken for the disappearance of edema, 2) gain in weight after the minimum body weight was reached, and 3) serum albumin regeneration. and methods the diet completely because cases were excluded from the Ten children who consumed others who consumed the followed for a period of 4 groups were comparable with and severity that a diet children is effective milk. as with Ten a skim observed skim good Twenty-two children with kwashiorkor were investigated. They were grossly underweight with varying levels of edema and hypoalbuminemia. In addition, some of them showed mental changes and skin changes. Their ages ranged from 1 to 5 years and their weights from 5 to 10 kg. The children were hospitalized for 4 to 5 weeks and were given diets which provided 4 g/kg of protein and 200 kcal/kg body wt. They were divided into two groups. One group received a diet based on opaque-2 maize and the other group received a skim milk diet. Children with severe anorexia refused to take the maize so they had to be given skim milk.

In recent years, efforts have been made to produce food grains of better nutritional quality. Opaque-2 maize is a variety of corn which contains higher amounts of lysine and tryptophan than ordinary corn. Studies in experimental animals have shown that PER value for opaque-2 maize is equal to that of milk protein (1, 2) and it has been suggested that this can replace milk in the diets of children in poor communities. A clinical trial was therefore undertaken to test the efficacy of opaque-2 maize in the treatment of protein-calorie malnutrition. Materials maize’ of the bulk.

These two regard to age, weight, Results Acceptability The skim milk diet was readily accepted by all the children but some difficulty was encountered in feeding the maize diet. They could not take the diet completely because of the bulk. Even the 10 children who consumed the maize diet had to be coaxed and persuaded to do so during the first 4 to 5 days. Once they recovered from the acute stage, however, feeding was no longer a problem. ‘From Council of the National Institute of Nutrition, Medical Research, Jamai-Osmania, bad-500007, of edema.

Gupta ABSTRACT and with TREATMENT Clinical OF KWASHIORKOR response There was littledifference between the two groups with regard to the rate of clinical improvement (Table 2). The time taken for the disappearance of edema ranged from 1 to 3 weeks in both groups. At the end of 4 weeks of treatment, the mean weight gain after the minimum body weight was reached was 0.7 kg in the group who received the maize diet and 0.9 kg in the children who received the skim milk one. Improvement of the associated signs of malnutrition such as the mental and skin changes also did not differ in these two groups.

However, these differences were not statistically significant. The results of the present study indicate that opaque-2 maize is effective in the treatment of kwashiorkor. The response observed in children who consumed the maize diet was comparable to that obtained with skim milk. The rise in serum albumin in these children was nearly 90% of that observed in children treated with skim milk. Earlier studies with different vegetable proteins have shown that although they are effective in controlling the acute clinical manifestations of kwashiorkor, they are inferior to skim milk as far as serum albumin regeneration is concerned (4). In this study, the mean rise in albumin level obtained with opaque-2 maize was I .08 g/ I 00 ml, which is close to the I .04 g/100 ml observed in the earlier experiment with bengal gram protein (4) and much higher than the values obtained with diets based on cottonseed (5), sesame, groundnut and cerealpulse combinations (4). Thus, the quality of the protein of SE. 9.3± 0.39 opaque-2 maize appears to be that of several vegetable proteins and close to that of milk protein.

A rise in serum albumin levels in these children was approximately 90% of that observed in children treated with skim milk, Because the nutritive quality of protein of opaque-2 maize is almost equivalent to that of milk protein, inclusion of this millet in the diets may be expected to improve the quality of the diet and thus improve the nutritional status of undernourished populations.

(New Series No. 6), New Delhi, Downloaded from ajcn.nutrition.org by guest on September 9, 2014 protein food, one of the most important is its nutritive value, Studies in experimental animals have shown that the PER value for opaque-2 maize is equivalent to that of casein (1, 2). The results of the present study as well as the balance studies reported in normal subjects (6-8) confirm the fact that the nutritive value of opaque-2 maize protein is indeed high and is well utilized by humans. Recipes containing opaque-2 maize as an ingredient can therefore be recommended as food supplements to prevent protein-calorie malnutrition in children. Though children with kwashiorkor who were acutely ill could not consume the maize diet completely, acceptability was found to be good after recovery and also among those children who were suffering from a mild or moderate degree of malnutrition. Maize is an important food crop in India and is well accepted by many people. Hybrid com has already gained popularity among our farmers. Recently, high-lysine maize composites,shakti and rattan, containing the opaque-2 gene have been developed at the Indian Agriculture Research Institute (9) and are now available for cultivation. Food grains of high nutritive quality have tremendous significance in the nutrition of people in many developing countries. Inclusion of such grains in the diets appears to be a practical approach to improve the protein nutritional status of the population. GUPTA
