Protein-calorie malnutrition (PCM) in Egypt immunological changes of salivary protein in PCM.

Whole saliva protein as well as the separated protein components were estimated in normal and malnourished Egyptian infants and young children. In normal, 8 protein components (Albumin, alpha1-antitrypsin, haptoglobin, beta2-lipoprotein, transferrin, IgA, IgM and IgG) were detected, while in PCM cases two more components (prealbumin and alpha2-macroglobulin) were found. The results also showed that the level of salivary protein components are markedly increased in edematous cases. In non-edeomatous ones, the level of these constituents are slightly increased in 3rd marasmus, but diminished in 2nd grade. It is concluded that the elevation of protein components in saliva of edematous cases could be a result of severe glandular tissue involvement as compared to controls and non-edematous cases. The value of IgA immunoglobulin as specific antibody originated from blood plasma and/or salivary glands may be used to reflect the extent of tissue affection in salivary glands of malnourished cases.

A study of the relationship between the energy contents of Schistosoma mansoni cercariae and their death during penetration of mammalian host skin.

Immersion of Biomphalaria pfeifferi in 1.5% glucose solution showed that the snails did not absorb any glucose during the first six hours but that almost 30% of the glucose was absorbed after 24 hours. The glycogen content of such "glucose-fed" snails was much higher than that of control normal snails. Cercariae of S. mansoni collected from the former snails exhibited a much lower level of death (20%), during penetration of mouse skin, than that of control normal cercariae (36%). It is suggested that death of S. mansoni cercariae during penetration of mammalian host skin is probably due to exhaustion of their energy reserves.

Diagnostic and prognostic significance of serum and urinary enzymes in nephropathies among Egyptian children.

Study of serum and urinary enzyme pattern in nephropathies revealed that before treatment, cases of both acute nephritis and nephrotic syndrome were found to have an increased activity of the three enzymes studied in both serum and urine (Alkaline and acid phosphatases and Lactic dehydrogenase). However, there was no constant correlation between the level of serum and urinary enzyme activities. Distorted pattern of the enzymes has a more protracted course in nephrotics. After treatment, serum and urinary enzymes tended to normalise in cases of acute glomerulonephritis. However, urinary alkaline phosphatase remained high nephrotics after clinical remission. In some cases of acute nephritis, a persistently high level of serum enzyme may indicate an incipient nephrotic element. Nephrotics not responding to the four weeks course of corticosteroid therapy have persistently high serum and urinary enzyme activities. Thus, estimation of serum and urinary enzyme pattern in nephropathies may be of diagnostic and prognostic value.
