1. The nutritional status of children showing no clinical signs of malnutrition, from the University School of Khon Kaen, Khon Kaen province, north-east Thailand and from two villages nearby, was tested. The children were grouped according to their body-weight expressed as a percentage of expected weight-for-height (Harvard standards (Stuart & Stevenson, 1959), as given by Jelliffe (1966)). 2. The differing prealbumin concentrations indicated that nutritional status differed between the groups. 3. The urinary urea: creatinine ratio was significantly lower in the village children compared with the children from Khon Kaen, indicative of the higher dietary protein intake of the latter. 4. alpha1-Acid glycoprotein and the first 'post-albumin peak' (obtained by polyacrylamide gel electrophoresis of serum and containing mainly mainly Gc-globulin, alpha1-antichymotrypsin and alpha1-B-glycoprotein) were found to be significantly higher in the village children compared with children from Khon Kaen. 5. The three main proteins of the first 'post-albumin peak' from polyacrylamide gel electrophoresis of serum were tested separately using the electroimmunoassay method. There was no significant difference in Gc-globulin between the children from Khon Kaen and the village children. The concentration of alpha1-B-glycoprotein from those Khon Kaen children whose body-weight was more than 95% expected weight-for-height was significantly lower compared with that of village children, alpha1-Antichymotrypsin concentration was significantly higher in serum from Khon Kaen children than in serum from village children.

Genetic polymorphism of GC (vitamin D-binding protein) in human urine was revealed by isoelectric focusing and immunoblotting on thin-layer polyacrylamide gels containing 2 M urea. Urine samples from 530 unrelated Japanese from the Fukui district, being only 1-2 ml of original urine, were examined, and correct GC typing was achieved by comparison with the results of direct grouping using plasma. Six common and twelve rare phenotypes were observed. The frequencies of the genes were 0.473 for GC*1F, 0.241 for GC*1S, 0.254 for GC*2, and 0.032 for the total of six rare alleles.

Human urine contains a spectrum of proteins derived from various organs in the body. This investigation was undertaken to identify a group of proteins secreted primarily by bladder urothelium. Saline bladder washouts were collected from 9 male and 4 female patients undergoing routine cystoscopic examination. Each sample was sieved, desalted, freeze-dried and solubilized in urea mix. identical amounts of proteins were pooled according to donor sex. All individual and pooled samples were then subjected to 2-dimensional gel analysis using the ISO-DALT system. Profiles of both groups of subjects were highly reproducible, comparable and resembled those of urine and plasma. Several hundred spots were visualized although most of them as yet remain unrecognized. The proteins identified in bladder washouts include albumin, transferrin, IgG gamma-heavy chain, Gc-globulin, alpha 1-antichymotrypsin, alpha 1-antitrypsin, alpha 1-acid glycoprotein, G4, IgG light chains, alpha 1-microglobulin, and low and high density lipoproteins. Most importantly, while some abundant urinary macromolecules such as Tamm-Horsfall mucoprotein and most acidic urinary proteins were undetectable, albumin and transferrin were relatively less expressed. The 2-dimensional profiles we developed can be used as a data base to study urothelium derived proteins in various disease conditions such as bladder cancer.

As part of our ongoing genetic studies, 2635 samples from 30 populations of the Indian subcontinent have been analyzed for GC subtype variation. Several rare variants were found and have been characterized using isoelectric focusing in 3 M urea and with an immobilized pH gradient and by comparison with known standards. Six new variants, 1A33, 2A22, 2A23, 2A24, 1C56, and 1C59, have been discovered in geographically and ethnically distant populations of the Indian subcontinent. Variants 1C11 and 1C21 have been reported previously in the French population and variant 1C36 has been reported in Nepalis, but all three variants were observed for the first time in the populations of India. The distribution of the rare variants in the Indian subcontinent was examined for anthropological usefulness for differentiation of Indian populations. The data for GC allele frequencies from 144 populations of India were compared for geographic and ethnic variation. A high frequency of the GC*IF allele was observed in populations of eastern India, and various ethnic groups from the eastern zone were clearly differentiated from similar ethnic populations from the rest of India. GC*2 allele frequency data were further correlated with various geographic and climatic variables, such as longitude, latitude, sunshine, solar radiation, and mean annual temperature. A significant positive correlation between GC*2 frequency and latitude was observed. The GC*2 allele frequency showed a cline increasing from south to north. Significant negative correlation was also observed between GC*2 frequency and sunshine, solar radiation, and mean temperature. A possible interpretation for selection of the GC*2 allele in areas with low levels of insolation is provided.
