The adult galactosemic phenotype

Postnatal glucocorticoid exposure alters the adult phenotype.

We examined the effect of six doses of dexamethasone (Dex) administered daily (2-7 days of age) to postnatal rats on body weight gain, food and water intake, peripheral hormonal/metabolic milieu, and hypothalamic neuropeptides that regulate food intake. We observed a Dex-induced acute (3 days of age) suppression of endogenous corticosterone and an increase in circulating leptin concentrations t...

Corneal re-epithelialization in galactosemic rats.

Abnormalities in corneal epithelial healing in diabetic patients have been described recently. Defects in corneal re-epithelialization in diabetic rats have been reported, and it was found that treatment with aldose reductase (AR) inhibitors effectively prevented these defects. Experiments using galactosemic rats to study further the role of AR in these defects, since AR is known to be the comm...

ADULT-TYPE HYPOLACTASIA: Genotype-phenotype correlation

Galactose oxidation using 13C in healthy and galactosemic children

Galactosemia is an inborn error of galactose metabolism that occurs mainly as the outcome of galactose-1-phosphate uridyltransferase (GALT) deficiency. The ability to assess galactose oxidation following administration of a galactose-labeled isotope (1-(13)C-galactose) allows the determination of galactose metabolism in a practical manner. We aimed to assess the level of galactose oxidation in ...

A simple and stable galactosemic cataract model for rats.

Rat galactosemic cataract is commonly used in the investigation of sugar cataract. In current study, 21-day sprague-dawley (SD) rats were randomly divided into two groups (n=42), which were fed by normal water and galactose solution (12.5%-10%) for 18 days respectively. Every 3 days, lens opacity was observed by a slit lamp, and 6 rats of each group were executed for the analysis of aldose redu...
