1. Serum proteins were studied in 106 children ranging from 3 to 14 years using a modification of Laurell's method of quantitative immunoelectrophoresis. 2. Quantitative values are given for eleven proteins, viz.: α1 lipoprotein, α1 antitrypsin, α1 easily precipitable glycoprotein, α1 group specific component, α2 macroglobulin, caeruloplasmin, haptoglobin, transferrin, haemopexin, β lipoprotein, and β1AC(C3). 3. There were no significant differences in protein levels between the sexes, and no correlation between age and protein level within the age range studied. 4. The values were also compared with those of infants aged 6–12 months, young adults of 16–25 years, and adults of 16–65 years.

Age Range

The T wave in the precordial V leads was studied in 187 normal children and young adults in the age range of 2 weeks to 20 years and in 164 individuals of like age with cardiovascular disease or with disease or medication capable of affecting the cardiovascular system. On the basis of this analysis correlated with a survey of the literature, it is concluded that: a. An upright T wave in lead V2 or leads further to the right should be considered abnormal in children between 2 weeks and 9 years of age until proved otherwise. b. The normal sequence in the direction of the T wave from V4R to V6 is from a negative to a positive wave with transitional forms which may be notched or diphasic. The reversal of this pattern is to be considered abnormal. c. The presence of unexpected T wave contours in specific leads at the different ages should be considered as evidence demanding re-examination of the ECG and of the child for abnormalities.

The level of total serum protein in the fowl has been followed from the 14th day of incubation to the 13th week of egg production. Serum proteins have been fractionated concurrently by zone electrophoresis in filter paper. Serum protein level in the 14-day embryo was 0.9 gm./100 ml. and the protein comprised a prealbumin fraction, albumin, α2- and β-globnlins. Sera from chicks aged seven days no longer contained a prealbumin fraction but α1-,α3- and γ-globulin fractions had appeared by this stage and the protein level had reached 2.3 gm./100 ml. Total serum protein in females increased to a maximum of about 5.4 gm./100 ml. in the week before laying of the first egg. By that time two new protein fractions had appeared. These new fractions accounted for the greater part of the increase over the levels (4.0 gm./100 ml.) prevailing in the prepuberal stage. Serum protein level declined during the first three weeks of laying to average levels below 4.0 gm./100 ml.; and this decline appeared to affect albumin and α1-globulin as well as the new fractions. As laying progressed, the total serum protein tended to regain a level around 4.0 gm./100 ml. The electrophoretic pattern also tended to return towards that prevailing in the week before laying. Some tentative correlations of the results of zone electrophoresis with published results for free electrophoresis of fowl serum proteins are presented.

Access To Water

SUMMARYSows housed with free access to water were found to have urine protein levels comparable to those recorded for man, dog and sheep. However, in stalled sows with restricted access to water, urine protein levels were twice as high as those of penned sows.Physiological proteinuria has been found to occur in the piglet, in which respect it is similar to the ruminant and the dog. Proteinuria reaches a peak within 20 hr of birth and lasts for approximately 48 hr. The rapid decline in urine protein levels after this period coincides with gut closure. Proteinuria did not occur in piglets fed on glucose saline, only in those receiving colostrum; however, the continued feeding of colostrum did not prolong the period of proteinuria. In piglets fed varying levels of colostral protein there was a direct correlation between serum protein levels and mean urinary protein concentration during the period of proteinuria, but there was no direct correlation between the amounts of colostral protein ingested and the serum protein level.

Abstract The effect of wounding and formation of regenerating wound tissue on the level of the serum proteins was studied in rats on a protein-free diet. It was found that the level of the globulin component having the third greatest electrophoretic mobility, probably part of the α2-globulin fraction, rose about 60% within 3 days after wounding and did not begin to return to normal until about 10 days later. Concomitantly, the level of the globulin with least mobility, presumably the -globulin component, decreased about 35% and also began to return to normal within 2 weeks after wounding. Varying the rate of healing, by the addition of protein or methionine to the diet, had no effect on the changes in the serum globulin levels. The newly formed α2-globulins were shown to be distinct from fetuin.

Protein Levels

The amount of protein in the serum depends on the balance between the rate of its synthesis, and that of its catabolism or loss. Abnormal metabolism may result from nutritional deficiency, enzyme deficiency, abnormal secretion of hormones, or the actions of drugs and toxins. Renal cancer is the third most common malignancy of the genitourinary system, and accounts for 3% of adult malignancies globally. Total serum proteins were measured in malignant kidney tumor, benign kidney tumors, and non tumoral kidney diseases patient groups, as well as in healthy individuals. A significant decrease (p< 0.001) of total serum protein levels in patients with malignant kidney tumors when compared with those of benign tumors, non tumoral diseases, and healthy individuals. The lowest serum protein levels were found in patients with stage IV, regardless their genders. Analysis of total serum proteins using PAGE revealed clear differences in the number and shape of the bands in patients with different kidney diseases compared with healthy controls.
