The purpose of this study was to investigate the effectiveness of 4-methylthiobenzoic acid (MTBA) as a protection agent against cisplatin (CDDP)-induced changes in organ of Corti surface structure, compared to electrophysiological changes. Electrophysiological change was assessed using auditory brainstem response (ABR) and morphological changes were(More)
Alstroemeria (Liliales) has two layers of petaloid tepals, in which the often spotted narrow inner tepals can be distinguished easily from the wider outer tepals. In order to explore this floral morphology in Alstroemeria, we investigated the tepal morphology and the expression patterns of three class B genes, whose homologs in eudicots have been shown(More)
We prepared antisera to both the N and C termini of amyloid beta-protein precursor (APP). Both antisera labeled 110 to 140 kd proteins from rat testis by immunoblotting. Northern blot analysis using oligonucleotide probes complementary to respective APPs showed that APPs expressed in rat testis contained Kunitz-type protease inhibitor domains.(More)
OBJECTIVES To determine the mechanism of intermediate- and high-level echinocandin resistance, resulting from heterozygous and homozygous mutations in GSC1 (FKS1), in both laboratory-generated and clinical isolates of Candida albicans. METHODS The DNA sequences of the entire open reading frames of GSC1, GSL1 (FKS3) and RHO1, which may contribute to the(More)
The subcellular localization of glucagon-like materials in the thalamus-hypothalamus and brain stem of the rat was investigated. Both glucagon immunoreactivity (GI) determined by C-terminal specific antibody and glucagon-like immunoreactivity (GLI) determined by non-specific antibody were enriched in the microsomal and synaptosomal fractions relative to the(More)
After introducing potassium ion through the round window into the perilymphatic space of 40 guinea pigs by means of iontophoresis, physiological and histochemical investigations were performed to determine the role of the high perilymphatic potassium concentration in the vertiginous attack of Ménière's disease. About 15 min after the iontophoretic(More)
Sixty-five guinea pigs were used to investigate the influence of rotatostimulations on the lateral crista ampullaris. After repeated turning stimulations with the cupulometric mode (the terminal turning velocity: 180 degrees/sec) for 24-72 hours, the morphological changes in the crista ampullaris on the ampullopetal flow side were compared with those on the(More)
The ganglionic blocking effects of the secondary and tertiary amines, mecamylamine and pempidine, on the spinal reflex of cats of both sexes were investigated. These blocking effects were then compared with findings in the quaternary ammonium compounds such as tetraethylammonium (TEA) and decamethonium (C10). Mecamylamine (5 mg/kg) and pempidine (1 mg/kg)(More)
