A Case of Partial Hypoxanthine-Guanine Phosphoribosyltransferase Deficiency Presenting as Uric Acid Lithiasis
Ji Hae Kim, Mi Jung Kim, Kee Hwan Yoo, Young Sook Hong, Joo Won Lee, Soon Kyum Kim
Clin Exp Pediatr. 2004;47(9):1020-1023.   Published online September 15, 2004
The deficiency of enzyme hypoxanthine-guanine phosphoribosyltransferase(HPRT) results in hyperuricemia and subsequently manifests in diverse symptoms. Lesch-Nyhan syndrome is a disorder characterized by hyperuricemia, mental retardation, choreoathetosis, spasticity and self-mutilation, resulting from complete deficiency of the enzyme, whereas partial deficiency of the enzyme shows symptoms of milder forms more often without abnormal neurologic signs. A 7-year-old boy with normal growth and...

Clin Exp Pediatr. 2004;47(4):430-438.   Published online April 15, 2004
Purpose : Unilateral ureteral obstruction(UUO), a well established experimental model of renal injury, gives rise to tubulointerstitial fibrosis, tubular dilatation and cellular atrophy. Angiotensin(ANG) II may take the prime role in the regulation of this response. The objectives in the current investigation were to determine whether the renal response to UUO involves the dedifferentiation of tubular epithelial cells to mesenchymal...
