Most cases with antituberculosis drug-induced hepatitis have been attributed to isoniazid. Isoniazid is metabolized by hepatic N-acetyltransferase (NAT) and cytochrome P450 2E1 (CYP2E1) to form hepatotoxins. However, the role of CYP2E1 in this hepatotoxicity has not yet been reported. The aim of this study was to evaluate whether the polymorphism of the(More)
The complete nucleotide sequence of the RNA genome of papaya ringspot virus (PRSV) was determined from four overlapping cDNA clones and by direct sequencing of viral RNA. The genomic RNA is 10326 nucleotides in length, excluding the poly(A) tract, and contains one large open reading frame that starts at nucleotide positions 86 to 88 and ends at positions(More)
The pelvic girdle, thigh, and calf muscles of 29 patients with Duchenne muscular dystrophy (DMD) were evaluated with magnetic resonance (MR) imaging. The muscles that were most resistant to disease were the gracilis, followed by the sartorius, semitendinous, and semimembranous. Sixteen patients had asymmetric involvement in part of the muscle bundles of(More)
OBJECTIVE To evaluate the predictive value of the antral follicle count in patients undergoing assisted reproductive technologies (ARTs). DESIGN Prospective study. SETTING Tertiary care institutional hospital. PATIENT(S) Consecutively seen patients undergoing ARTs such as IVF-ET, gamete intrafallopian transfer, and tubal embryo transfer (TET). (More)
Using the polymerase chain reaction/single strand conformation polymorphism (PCR/SSCP), we studied the molecular characterization of 97 (86 male and 11 female) glucose-6-phosphate dehydrogenase (G6PD) deficient Chinese newborn babies and infants in southern Taiwan. Movement shifts were clearly seen in exon 2, 5, 6 and 12, respectively. No movement shift was(More)
The in vitro corneal penetration and in vivo corneal absorption of acyclovir from an acyclovir-containing liposome system were investigated. Results of in vitro corneal penetration demonstrated that positively charged liposomes resulted in a penetration rate lower than those of negatively charged liposomes and free acyclovir in solution. An in vivo study(More)
Chitosan is a cationic biopolymer derived from chitin with potential therapeutic applications such as controlled drug delivery to mucosal-epithelial surfaces in the body. Inhaled chitosan microparticles (CM), for example, are of potential interest in pulmonary pharmacotherapy. In this context, we examine some basic reactions of lung tissue to CM. Inhaled CM(More)
Apocynin suppresses the generation of reactive oxygen species (ROS) that are implicated in ventilator-induced lung injury (VILI). We thus hypothesized that apocynin attenuates VILI. VILI was induced by mechanical ventilation with tidal volume (V t) of 15 ml/kg in isolated and perfused rat lung. Apocynin was administered in the perfusate at onset of(More)
To identify changes in catecholamine levels and beta-adrenergic receptor density in children with varying degrees of congestive heart failure, we measured plasma norepinephrine (NE), epinephrine, and beta-adrenergic receptor levels in 91 noncyanotic patients using high-performance liquid chromatography and a radioligand binding assay. Plasma NE levels in 41(More)
BACKGROUND AND OBJECTIVES Recent family-based studies have revealed a linkage between human chromosome 5q31 and asthma, elevated serum IgE levels and airway hyperresponsiveness (AHR). Among the candidate genes in this region is the gene encoding IL-4. This gene could be a candidate gene for asthma. The aim of this prospective case-control study was to(More)
