Characterization of the ilv-2 gene from Neurospora crassa encoding alpha-keto-beta-hydroxylacyl reductoisomerase.

We have isolated the cDNA and corresponding genomic DNA for the ilv-2 locus of Neurospora crassa. This gene encodes alpha-keto-beta-hydroxylacyl reductoisomerase (Ilv-2), required for the synthesis of isoleucine and valine. The gene contains four introns, maps to the right arm of chromosome V, and encodes a protein of 400 amino acids (aa). Alignment of the aa sequence of Ilv-2 with the two other known eukaryotic sequences encoding this enzyme reveals two conserved regions.

The pigtail probe protected by silicone intubation: a combined approach to canalicular reconstruction.

We have devised a method of single-eyelid canalicular reconstruction using the pigtail probe to facilitate identification of the proximal canalicular segment following silicone stent intubation of the normal, uninjured canaliculus. A series of seven acute and two long-standing canalicular lacerations were successfully reconstructed using this technique, which minimizes the risks associated with the use of the pigtail probe.

Altered fractional excretion of uric acid during total parenteral nutrition.

The presence of crystal proven podagra coincident with a 52% decrease in plasma urate after a 3-day course of total parenteral nutrition (TPN) prompted a study of urate excretion in 9 patients with Crohn's disease. By Day 9 in those receiving TPN, plasma urate decreased 58% (p less than 0.001), while fractional urate excretion increased 94% (p less than 0.005). Twenty-four hour urate excretion and serum creatinine were not significantly altered. These findings persisted for the duration of TPN. In 2 patients with ileocolitis, the addition or deletion of either lipid emulsion or multivitamin infusions during TPN had no effect on urate values. Rather, the amino acid load or a specific constituent appears to be the causal factor. These data suggest that hypouricemia due to extensive net urate excretion is common during TPN therapy. Finally, patients with established gout may be at risk for acute gouty attacks during TPN therapy.
