OBJECTIVES To confirm that laryngotracheal separation (LTS) is a satisfactory treatment for patients with intractable aspiration pneumonia, even though it does not require tracheoesophageal anastomosis. STUDY DESIGN Retrospective. METHODS Nine patients with intractable aspiration pneumonia underwent LTS at our institution from 1996 to 1999. Two patients(More)
The transport kinetics of amino-beta-lactam antibiotics was studied by an in situ rat small intestinal recirculating perfusion technique. The disappearance rates of the antibiotics from the perfusing luminal solution followed mixed-type kinetics with saturable and nonsaturable processes. The kinetic parameters were determined. Pharmacokinetic analysis of(More)
Ocular manifestations in two cases of congenital muscular dystrophy of Fukuyama type were reported. This disease is characterized by early onset of hypotonia, generalized muscle weakness and atrophy, mental retardation, and elevated serum creatine-phosphokinase activity. The symptoms include entropion of lower lids, pathological myopia with astigmatism,(More)
The disposition characteristics of beta-lactam antibiotics in rats were investigated, and a physiologically based pharmacokinetic model capable of predicting the tissue distribution and elimination kinetics of these drugs was developed. Protein-binding parameters in rat serum were determined by equilibrium dialysis. Linear binding was found for penicillin(More)
The degradation rate, solubility, and dissolution rate of amino penicillins, amoxicillin, ampicillin, epicillin, and cyclacillin, were determined quantitatively as a function of pH. In the pH range studied, 0.30-10.50, the degradation of amoxicillin and epicillin followed pseudo-first-order kinetics to give the same type of pH-rate profiles as those of(More)
A highly infectious cDNA clone of clover yellow vein virus (pClYVV) was tested as a viral vector, especially for legume species. The genes for green fluorescent protein (GFP) and soybean glutamine synthetase (GS) were inserted between the genes for P1 and HC-Pro on pClYVV to create three recombinant plasmids: pClYVV-GFP, pClYVV-GFP-GS, and pClYVV-GFP:GS. In(More)
We studied family members of 9 patients with falciform retinal fold, and found a number of cases showing features of familial exudative vitreoretinopathy (FEVR) in the fundi. Retinal fold was also seen in the eye of a cousin of the propositus. Three cases with falciform retinal fold were bilateral and 7 cases were unilateral. Retinal folds were located in(More)
The absorption of cyclacillin at pH 7.0 by the rat small intestine was investigated using in situ perfusion. At the lowest dose of 95 microgram/ml, the antibiotic disappearance was rapid and followed first-order kinetics, with the disappearance being 85% at 100 min. At the intermediate concentrations of 770 and 1200 microgram/ml, the disappearance after 100(More)
The disappearance of various beta-lactam antibiotics from in situ rat small intestinal loops was studied at pH 7.4. For monobasic penicillins, despite the wide variety of apparent partition coefficients in isobutyl alcohol-water, the disappearance from the jejunal loops was almost 30% (+/- 5% SD). On the other hand, the disappearance of amphoteric(More)
