Abstract:
A neonate with transposition of the great arteries (TGA) was scheduled for arterial switch operation (ASO) and entered to Pediatric ICU on day 4. Although mainly fed with mother's and formula milk, the serum natrium concentration decreased extremely to 104 mEq x l(-1) on day 9. We prioritized treatment of electrolyte disorders, and the operation was postponed on day 13. After the operation, he was diagnosed as syndrome of inappropriate secretion of antidiuretic hormone (SIADH) and post operative course was uneventful. Electrolyte control is very important even if the infant is fed with mother's milk.

Glucose Transporters
Facilitated diffusion-glucose transporters (GLUTs) are encoded by the solute-linked carrier (SLC) family 2, subfamily A gene family, or SLC2A. The 14 GLUT protein members are distributed into three classes:

Renal Tubule and Collecting Duct
Proximal Convoluted Tubule (PCT):
The PCT is the initial segment of the renal tubule, extending from the Bowman's capsule that encloses the glomerulus. Its convoluted structure and microvilli-lined cells increase the surface area for reabsorption. The PCT reabsorbs glucose, amino acids, sodium, and water from the filtrate, ensuring essential...
