Late effects of breast-feeding and early weaning: seven-year prospective study in children.

The effect of breast feeding on some clinical and thyroid function parameters was studied in a prospective longitudinal study from birth up to 7 years of age. At the ages 1-7 years, the obesity rates observed in children breast-fed for less than 3 months were substantially higher than in children who had been breast-fed over longer intervals. Mean age when obesity was reported was similar in all groups (4-5 years).

Thyroliberin (TRH) and TRH free acid (TRH-OH) present in milk do not originate from local synthesis in mammary gland.

Unlabelled: Hypothalamic hormones represent a peculiar group of hormones present in milk in surprisingly high concentrations. High levels of these neuropeptides raised the question of their origin. The hypothesis suggesting local synthesis of TRH in the mammary gland was, therefore, tested.

[24-hour measurement of pH and its significance in the diagnosis of gastroesophageal reflux in children].

During 1987-1989 the authors examined 57 patients; reflux disease was detected in 33 (i.e. 57.

[Lipoprotein profiles in 6-year-old children breast fed for different periods of time].

The authors submit results of investigations of the lipoprotein profile in six-year-old children fed a different diet during infancy. It is the continuation of previous results of a long-term longitudinal investigation of this group of healthy children which revealed a favourable effect of breastfeeding on the cholesterol distribution in lipoprotein fractions. Throughout the investigation the children were divided into four groups according to the breastfeeding period.

[The effect of different types of infant nutrition on indicators of lipid metabolism in 1-to-4-year-old children].

The authors present the results obtained in investigations of the influence of different infant diets on some indicators of lipid metabolism in a group of healthy children followed up from birth and aged 1-4 years at the time of the investigation. The work is a continuation of previous investigations which provided evidence of the influence of breastfeeding on blood lipid levels and the cholesterol distribution in different lipoprotein fractions during the early postnatal period. The analysis of the plasma cholesterol and lipoprotein cholesterol in children breastfed for varying periods and children not breastfed bottlefed) at the age of 1, 1.

Thyrotropin releasing hormone in the pancreas of newborn rats from streptozotocin-treated mothers.

The effect of maternal diabetes (induced by i.p. injections of 40-50 mg/kg BW Streptozotocin on the day of mating) on TRH in the pancreas of newborn rats was studied.

Exchange transfusion in premature newborns: effect of maturity on thyrotropin and thyroxine responses.

The effects of exchange transfusion on plasma T4 and TSH were studied in two groups of premature newborns to evaluate the effect of maturation on the reactivity of the pituitary-thyroid axis. In newborns with a birth weight between 1900-2500 g (gestational age 35.4 +/- 0.

Effect of breast-feeding on infant thyroid activity: 3 year follow up--longitudinal study.

The effect of breast-feeding on serum thyroid hormones and TSH was studied in a longitudinal study from birth up to 3 years. T4 was found to be significantly higher in breast-fed than in weaned infants at the age of 4 and 6 months and so was rT3 at the age 4 months. The body weight of breast-fed girls at the age 4 and 6 months was lower than that of formula-fed ones.

Role of thyrotropin-releasing hormone in thyroid-stimulating hormone and growth hormone regulation during postnatal maturation in female Wistar rats.

The role of endogenous thyrotropin-releasing hormone (TRH) in the control of pituitary thyroid-stimulating hormone (TSH) and growth hormone (GH) secretion was studied during postnatal maturation in female Wistar rats. Half of the sucklings in each litter was treated intraperitoneally with either specific rabbit antiserum against TRH or normal rabbit serum (0.1-0.
