Carcionoembryonic antigen and immunoglobulin IgE in coeliac disease, food allergy and dudenal ulcer disease in children.

The aim of this study was to estimate the behaviour of carcinoembryonic antigen (CEA) and immunoglobulin IgE level in children with coeliac disease (CD), food allergy (FA) and duodenal ulcer disease (UD). In total, 390 determinations of CEA (201 for CD, 27 for FA and 162 for UD) and 558-IgE (238, 136 and 184, respectively) were carried out during disease aggravations and remissions. The analysis of CEA mean values with respect to sex revealed no differences while IgE level in boys with UD was twice as high as in girls.

[Growth hormone concentration following various factors stimulating its release].

Growth hormone concentration has been assayed in 105 children (45 girls and 60 boys) during starvation and following its stimulation with clonidine and insulin and during the sleep. A significant difference between growth hormone concentration during fasting and after stimulation has been noted. No statistically significant difference between growth hormone concentrations during the sleep and following insulin has been found.

[Further steps in regional localization of the gene coding for human arylsulfatase B (ARSB): gene assignment to the section q11-qter of chromosome 5].

The structural gene coding for human arylsulfatase B (ARSB) has been assigned to chromosome 5 and then to 5p11-5qter by means of somatic cell hybridization. The somatic cell hybrids used in the present studies were derived from fusion experiments between Chinese hamster, a3 line (TK-) and human leukocytes from a patient carrying the reciprocal balanced translocation t (5;21) (q11;q22) according to the method described previously. About 90 independent hybrid clones were selected for further analysis.

Triiodothyronine and thyroxine in human, cow's and formula milk.

Triiodothyronine concentration in extracted human, cow's and formula milk was measured. The highest concentration (mean +/- SD = 1.56 +/- 1.
