Abstract
Across multiancestry groups, we analyzed Human Leukocyte Antigen (HLA) associations in over 176,000 individuals with Parkinson's disease (PD) and Alzheimer's disease (AD) versus controls. We demonstrate that the two diseases share the same protective association at the HLA locus. HLA-specific fine-mapping showed that hierarchical protective effects of HLA-DRB1*04 subtypes best accounted for the association, strongest with HLA-DRB1*04:04 and HLA-DRB1*04:07, and intermediary with HLA-DRB1*04:01 and HLA-DRB1*04:03. The same signal was associated with decreased neurofibrillary tangles in postmortem brains and was associated with reduced tau levels in cerebrospinal fluid and to a lower extent with increased Aβ42. Protective HLA-DRB1*04 subtypes strongly bound the aggregation-prone tau PHF6 sequence, however only when acetylated at a lysine (K311), a common posttranslational modification central to tau aggregation. An HLA-DRB1*04-mediated adaptive immune response decreases PD and AD risks, potentially by acting against tau, offering the possibility of therapeutic avenues.

Abstract
Genome-wide association studies (GWAS) suggest that the genetic architecture of complex diseases consists of unexpectedly numerous variants with small effect sizes. However, the polygenic architectures of many diseases have not been well characterized due to lack of simple and fast methods for unbiased estimation of the underlying proportion of disease-associated variants and their effect-size distribution. Applying empirical Bayes estimation of semi-parametric hierarchical mixture models to GWAS summary statistics, we confirmed that schizophrenia was extremely polygenic [~40% of independent genome-wide SNPs are risk variants, most within odds ratio (OR = 1.03)], whereas rheumatoid arthritis was less polygenic (~4 to 8% risk variants, significant portion reaching OR = 1.05 to 1.1). For rheumatoid arthritis, stratified estimations revealed that expression quantitative loci in blood explained large genetic variance, and low- and high-frequency derived alleles were prone to be risk and protective, respectively, suggesting a predominance of deleterious-risk and advantageous-protective mutations. Despite genetic correlation, effect-size distributions for schizophrenia and bipolar disorder differed across allele frequency. These analyses distinguished disease polygenic architectures and provided clues for etiological differences in complex diseases.

Abstract
Coronary artery disease (CAD) including myocardial infarction is one of the leading causes of death in many countries. Similar to other common diseases, its pathogenesis is thought to result from complex interactions among multiple genetic and environmental factors. Recent large-scale genetic association analysis for CAD identified 15 new loci. We examined the reproducibility of these previous association findings with 7990 cases and 6582 controls in a Japanese population. We found a convincing association of rs9319428 in FLT1, encoding fms-related tyrosine kinase 1 (P=5.98 × 10(-8)). Fine mapping using tag single-nucleotide polymorphisms (SNPs) at FLT1 locus revealed that another SNP (rs74412485) showed more profound genetic effect for CAD (P=2.85 × 10(-12)). The SNP, located in intron 1 in FLT1, enhanced the transcriptional level of FLT1. RNA interference experiment against FLT1 showed that the suppression of FLT1 resulted in decreased expression of inflammatory adhesion molecules. Expression of FLT1 was observed in endothelial cells of human coronary artery. Our results indicate that the genetically coded increased expression of FLT1 by a functional SNP implicates activation in an inflammatory cascade that might eventually lead to CAD.

Abstract
Whole exome sequencing (WXS) is widely used to identify causative genetic mutations of diseases. However, not only have several commercial human exome capture platforms been developed, but substantial updates have been released in the past few years. We report a performance comparison for the latest release of four commercial platforms, Roche/NimbleGen’s SeqCap EZ Human Exome Library v3.0, Illumina’s Nextera Rapid Capture Exome (v1.2), Agilent’s SureSelect XT Human All Exon v5 and Agilent’s SureSelect QXT, using the same DNA samples. Agilent XT showed the highest target enrichment efficiency and the best SNV and short indel detection sensitivity in coding regions with the least amount of sequencing. Agilent QXT had slightly inferior target enrichment than Agilent XT. Illumina, with additional sequencing, detected SNVs and short indels at the same quality as Agilent XT, and showed the best performance in coverage of medically interesting mutations. NimbleGen detected more SNVs and indels in untranslated regions than the others. We also found that the platforms, which enzymatically fragment the genomic DNA (gDNA), detected more homozygous SNVs than those using sonicated gDNA. We believe that our analysis will help investigators when selecting a suitable exome capture platform for their particular research.

Abstract
Recent genome-wide association studies (GWAS) have identified several novel single nucleotide polymorphisms (SNPs) associated with type 2 diabetes (T2D). Various models using clinical and/or genetic risk factors have been developed for T2D risk prediction. However, analysis considering algorithms for genetic risk factor detection and regression methods for model construction in combination with interactions of risk factors has not been investigated. Here, using genotype data of 7,360 Japanese individuals, we investigated risk prediction models, considering the algorithms, regression methods and interactions. The best model identified was based on a Bayes factor approach and the lasso method. Using nine SNPs and clinical factors, this method achieved an area under a receiver operating characteristic curve (AUC) of 0.8057 on an independent test set. With the addition of a pair of interaction factors, the model was further improved (p-value 0.0011, AUC 0.8085). Application of our model to prospective cohort data showed significantly better outcome in disease-free survival, according to the log-rank trend test comparing Kaplan-Meier survival curves (p--value 2:09 x 10(-11)). While the major contribution was from clinical factors rather than the genetic factors, consideration of genetic risk factors contributed to an observable, though small, increase in predictive ability. This is the first report to apply risk prediction models constructed from GWAS data to a T2D prospective cohort. Our study shows our model to be effective in prospective prediction and has the potential to contribute to practical clinical use in T2D.

Abstract
BACKGROUND & AIMS Crohn's disease is an inflammatory bowel disease induced by multiple genetic and environmental factors. Genome-wide association studies have identified genetic factors that affect the risk for Crohn's disease in European populations, but information from other ethnic groups is scarce. We therefore investigated genetic factors associated with Crohn's disease in the Japanese population. METHODS We performed a genome-wide association study with 372 individuals with Crohn's disease (cases) and 3389 controls, all from the Japanese population. To confirm identified associations, we performed a replication study with an independent panel of 1151 Crohn's disease cases and 15,800 controls. We also performed an association analysis using genome-wide genotype imputation in the discovery cohort. RESULTS We confirmed associations of Crohn's disease with variants in MHC (rs7765379, P = 2.11 × 10(-59)), TNFSF15 (rs6478106, P = 3.87 × 10(-45)), and STAT3 (rs9891119, P = 2.24 × 10(-14)). We identified 2 new susceptibility loci: on chromosome 4p14 (rs1487630, P = 2.40 × 10(-11); odds ratio, 1.33), and in the SLC25A15-ELF1-WBP4 region on 13q14 (rs7329174 in ELF1, P = 5.12 × 10(-9); odds ratio, 1.27). CONCLUSIONS In a genome-wide association study, we identified 2 new susceptibility loci for Crohn's disease in a Japanese population. These findings could increase our understanding of the pathogenesis of Crohn's disease.

Abstract
Prostate specific antigen (PSA) is widely used as a diagnostic biomarker for prostate cancer (PC). However, due to its low predictive performance, many patients without PC suffer from the harms of unnecessary prostate needle biopsies. The present study aims to evaluate the reproducibility and performance of a genetic risk prediction model in Japanese and estimate its utility as a diagnostic biomarker in a clinical scenario. We created a logistic regression model incorporating 16 SNPs that were significantly associated with PC in a genome-wide association study of Japanese population using 689 cases and 749 male controls. The model was validated by two independent sets of Japanese samples comprising 3,294 cases and 6,281 male controls. The areas under curve (AUC) of the model were 0.679, 0.655, and 0.661 for the samples used to create the model and those used for validation. The AUCs were not significantly altered in samples with PSA 1-10 ng/ml. 24.2% and 9.7% of the patients had odds ratio <0.5 (low risk) or >2 (high risk) in the model. Assuming the overall positive rate of prostate needle biopsies to be 20%, the positive biopsy rates were 10.7% and 42.4% for the low and high genetic risk groups respectively. Our genetic risk prediction model for PC was highly reproducible, and its predictive performance was not influenced by PSA. The model could have a potential to affect clinical decision when it is applied to patients with gray-zone PSA, which should be confirmed in future clinical studies.

Abstract
To identify a novel susceptibility locus for type 2 diabetes, we performed an imputation-based, genome-wide association study (GWAS) in a Japanese population using newly obtained imputed-genotype data for 2 229 890 single-nucleotide polymorphisms (SNPs) estimated from previously reported, directly genotyped GWAS data in the same samples (stage 1: 4470 type 2 diabetes versus 3071 controls). We directly genotyped 43 new SNPs with P-values of <10(-4) in a part of stage-1 samples (2692 type 2 diabetes versus 3071 controls), and the associations of validated SNPs were evaluated in another 11 139 Japanese individuals (stage 2: 7605 type 2 diabetes versus 3534 controls). Combined meta-analysis using directly genotyped data for stages 1 and 2 revealed that rs515071 in ANK1 and rs7656416 near MGC21675 were associated with type 2 diabetes in the Japanese population at the genome-wide significant level (P < 5 × 10(-8)). The association of rs515071 was also observed in European GWAS data (combined P for all populations = 6.14 × 10(-10)). Rs7656416 was in linkage disequilibrium to rs6815464, which had recently been identified as a top signal in a meta-analysis of East Asian GWAS for type 2 diabetes (r(2) = 0.76 in stage 2). The association of rs7656416 with type 2 diabetes disappeared after conditioning on rs6815464. These results indicate that the ANK1 locus is a new, common susceptibility locus for type 2 diabetes across different ethnic groups. The signal of association was weaker in the directly genotyped data, so the improvement in signal indicates the importance of imputation in this particular case.

Abstract
OBJECTIVE Povidone-Iodine preparation is used as a disinfectant in otological surgeries. The ototoxicity of Povidone-Iodine preparation was evaluated using infant, young and adult guinea pigs. The effects of different concentrations and of different exposure durations on compound action potentials were also studied. MATERIALS & METHODS Povidone-Iodine was used to fill one middle ear cavity of the guinea pig, and the compound action potential (CAP) was measured from the round window membrane at 24h, 7 days, and 28 days. The contralateral side was filled with saline as control. Test sounds used were clicks and tone bursts of 2, 4, and 8 kHz. RESULTS At 24h, Povidone-Iodine solution showed a significant toxic effect in the infant group. In the young animal group, no toxic effect was seen. In the adult group, a mild degree of deafness for 2 kHz was found. At 7 days, the young group showed significant hearing loss for all frequencies, but the adult group did not show any hearing loss. With a half strength solution, both young and adult group did not show hearing loss. At 28 days, with a full strength solution, hearing loss became prominent for all sound stimulation. With 1/8th dilution, the young group showed a moderate hearing loss, but the adult group did not. CONCLUSION The thicker round window membrane in human is expected to provide more protection to the human cochlea than in the guinea pig model that we have studied. Mild hearing loss at 24h and 7 days using 10% solution, but no hearing loss with 5% solution at 7 days may indicate that rinsing of the middle ear cavity with saline during surgery should minimize the ototoxic effect of this product. The age of the animals does influence the outcome of the ototoxicity experiment. From this experiment, Povidone-Iodine preparations in the infant should be used with caution. Povidone scrub should not be used for otologic surgery.

Abstract
Chronic viral hepatitis is the most important risk factor for progression to hepatocellular carcinoma (HCC). To identify genetic risk factors for progression to HCC in individuals with chronic hepatitis C virus (HCV), we analyzed 467,538 SNPs in 212 Japanese individuals with chronic HCV with HCC and 765 individuals with chronic HCV without HCC. We identified one intronic SNP in the DEPDC5 locus on chromosome 22 associated with HCC risk and confirmed the association using an independent case-control population (710 cases and 1,625 controls). The association was highly significant when we analyzed the stages separately as well as together (rs1012068, P(combined) = 1.27 × 10(-13), odds ratio = 1.75). The significance level of the association further increased after adjustment for gender, age and platelet count (P = 1.35 × 10(-14), odds ratio = 1.96). Our findings suggest that common variants within the DEPDC5 locus affect susceptibility to HCC in Japanese individuals with chronic HCV infection.

Abstract
Recent genome-wide association studies reported strong and reproducible associations of multiple genetic variants in a large "gene-desert" region of chromosome 8q24 with susceptibility to prostate cancer (PC). However, the causative or functional variants of these 8q24 loci and their biological mechanisms associated with PC susceptibility remain unclear and should be investigated. Here, focusing on its most centromeric region (so-called Region 2: Chr8: 128.14-128.28 Mb) among the multiple PC loci on 8q24, we performed fine mapping and re-sequencing of this critical region and identified SNPs (single nucleotide polymorphisms) between rs1456315 and rs7463708 (chr8: 128,173,119-128,173,237 bp) to be most significantly associated with PC susceptibility (P = 2.00 × 10(-24) , OR = 1.74, 95% confidence interval = 1.56-1.93). Importantly, we show that this region was transcribed as a ∼13 kb intron-less long non-coding RNA (ncRNA), termed PRNCR1 (prostate cancer non-coding RNA 1), and PRNCR1 expression was upregulated in some of the PC cells as well as precursor lesion prostatic intraepithelial neoplasia. Knockdown of PRNCR1 by siRNA attenuated the viability of PC cells and the transactivation activity of androgen receptor, which indicates that PRNCR1 could be involved in prostate carcinogenesis possibly through androgen receptor activity. These findings could provide a new insight in understanding the pathogenesis of genetic factors for PC susceptibility and prostate carcinogenesis.

Abstract
Lung cancer is the most common cause of death from cancer worldwide, and its incidence is increasing in East Asian and Western countries. To identify genetic factors that modify the risk of lung adenocarcinoma, we conducted a genome-wide association study in a Japanese cohort, with replication in two independent studies in Japanese and Korean individuals, in a total of 2,098 lung adenocarcinoma cases and 11,048 controls. The combined analyses identified two susceptibility loci for lung adenocarcinoma: TERT (rs2736100, combined P = 2.91 × 10⁻¹¹), odds ratio (OR) = 1.27) and TP63 (rs10937405, combined P = 7.26 × 10⁻¹²), OR = 1.31). Fine mapping of the region containing TP63 showed that a SNP (rs4488809) in intron 1 of TP63 showed the most significant association. Our results suggest that genetic variation in TP63 may influence susceptibility to lung adenocarcinoma in East Asian populations.

Abstract
The aim of this study was to isolate single-chain variable fragments (scFvs) against human insulin-like growth factor I receptor (IGFIR) from a phage library displaying human scFvs. Isolated scFvs-displaying phages showed affinity for IGF-IR in comparison to the control. Expression of scFv proteins in Escherichia coli for further characterization, however, proved extremely difficult. Alternatively, the scFv protein was expressed as a fusion protein with a maltose-binding protein (MBP) that is a highly soluble E. coli protein. The MBPscFv fusion protein expressed in a soluble form in E. coli was purified to homogeneity by two-step affinity chromatography. The resulting MBP-scFv exhibited affinity for IGF-IR and structurally-related insulin receptor (IR). These results suggest both that MBPscFv fusion proteins are practical alternatives to isolating scFv proteins for further characterization and that successful isolation of human scFvs against a specific protein of interest requires vigorous screening in the early stages. Such screening is accomplished by using two independent screening methods such as measuring binding to IGF-IR but not to IR by ELISA or measuring competitive binding by IGF-I in addition to binding to IGF-IR alone.

Abstract
We describe the Phase II HapMap, which characterizes over 3.1 million human single nucleotide polymorphisms (SNPs) genotyped in 270 individuals from four geographically diverse populations and includes 25-35% of common SNP variation in the populations surveyed. The map is estimated to capture untyped common variation with an average maximum r2 of between 0.9 and 0.96 depending on population. We demonstrate that the current generation of commercial genome-wide genotyping products captures common Phase II SNPs with an average maximum r2 of up to 0.8 in African and up to 0.95 in non-African populations, and that potential gains in power in association studies can be obtained through imputation. These data also reveal novel aspects of the structure of linkage disequilibrium. We show that 10-30% of pairs of individuals within a population share at least one region of extended genetic identity arising from recent ancestry and that up to 1% of all common variants are untaggable, primarily because they lie within recombination hotspots. We show that recombination rates vary systematically around genes and between genes of different function. Finally, we demonstrate increased differentiation at non-synonymous, compared to synonymous, SNPs, resulting from systematic differences in the strength or efficacy of natural selection between populations.

Abstract
OBJECTIVE The objective of this study is to evaluate the safety of two ear drops, Ofloxacin (OFLX: Taribid Otic Solution, Daiichi Seiyaku) and Fosfomycin sodium (FOM: Fosmicin S, Meiji Seiyaku). METHODS Albino guinea pigs were used as experimental animals, and the ototoxicity was evaluated by means of threshold changes in the compound action potentials (CAP), when topically applied to the middle ear cavity of the guinea pig. The sound stimuli applied were; click sound, with tone bursts of 8 kHz, 4 kHz, and 2 kHz. In one group of animals, after one application of the ear drops in the right middle ear cavity, the change in CAP was compared with a contralateral saline control at 24h, one week, and four weeks. In other group of animals, the ear drops were applied into the middle ear cavity for seven consecutive days and the CAP was measured at 24h. RESULTS At 24h the CAP threshold for click, 8 and 4 kHz elevated significantly for both the saline and ear drop treatment, but the threshold returned to normal when measured at 7 days and 28 days. Seven consecutive days of ear drops administration resulted in no reduction in the CAP for either ear drops. CONCLUSIONS Based on the lack of changes in the CAP, these two ear drops studied did not show any significant ototoxicities.

Abstract
To investigate the role of cervical proprioceptive inputs in the process of vestibular compensation, we performed static posturography in patients with acute and compensated unilateral vestibular dysfunction, by applying vibratory stimulation to the dorsal neck muscles. Neck vibration induced disequilibrium in both groups of patients, but was more pronounced in the compensated patients. These results indicate that manipulation of the neck afferents causes discompensation in subjects whose vestibular dysfunction has already been compensated by multisensory inputs including neck afferents.

Abstract
A large negative deflection with a latency of 3 ms was observed in the auditory brainstem response (ABR) waveforms of some patients with peripheral profound deafness. This deflection was termed the N3 potential. In this paper, we review patients with the N3 potential and discuss the characteristics of abnormal ABR waveforms. The origin of the N3 potential was also discussed, especially with respect to vestibular evoked potentials. In most of the patients, audiograms showed no response to the maximum output of an audiometer in the high-frequency range and a residual response in the low-frequency range. The N3 potentials were noted at intensities of 80 dB nHL or greater. As the stimulus intensity increased, the amplitude of the potential increased and the latency decreased. A high repetition rate (83.3/s) of the click stimulus influenced the latency and amplitude of the N3 potential. The potential was replicated on retest within less than a month, and had a consistent latency and amplitude over the scalp. The results indicate that the N3 potential is not an electrical artifact but a physiological neural response evoked by a loud sound. The N3 potential is most likely not an auditory evoked response from cochlear or a response from a semicircular canal, because it has a 3-ms latency, a sharp waveform, and is unassociated with vertigo. The results suggest that the N3 potential may be a saccular acoustic response.

Abstract
The supratubal recess (STR), located superior to the bony eustachian tube and anterior to the attic and often the site of disease, is clearly separated from the attic by the presence of a bony partition. Its anatomic development in childhood, however, remains nuclear. We reviewed serial horizontal sections of fetal and children's temporal bones from the collection of the Otopathology Laboratory, University of Minnesota. Apparently, upward expansion of the bony eustachian tube begins at a late fetal stage and continues throughout childhood, thus forming the STR. Our finding that the STR had already developed in temporal bones without pneumatization of petrous bone suggests that its formation is independent of the air-cell system. Absorption of mesenchymal tissue in the STR tends to be slower than elsewhere in the temporal bone. Surrounded solely by petrous bone, the STR seems, both developmentally and anatomically, a distinctive compartment of the middle ear.

Abstract
Three-component analysis of Benign Paroxysmal Positional Nystagmus (BPPN), focusing on the horizontal, vertical, and torsional, using a computerized eye movement analysis system, was carried out in 10 patients. Using a pendular rotation stimulus, we also measured three components of eye movement elicited from the vertical semicircular canals in normal subjects. We compared two components (vertical and torsional) of BPPN with that of eye movements elicited from the vertical semicircular canals. In BPPN, the torsional component of eye movements was larger than that of the vertical component. Conversely, the vertical component from the vertical semicircular canals was larger than that of the torsional component. From these results, by analysing the vestibulo-ocular reflex of the vertical semicircular canals, it is difficult to support the idea that the pathology of the BPPV is localized in the posterior semi-circular canal alone.

Abstract
The acoustic biasing technique using low-frequency sound is of increasing interest to investigators, not only as a means of studying cochlear transduction but also as a promising tool for assessing cochlear pathology such as endolymphatic hydrops. We compared normal modulation patterns of round window responses in guinea pigs and chinchillas, whose low-frequency auditory characteristics are known to be different. A 50-Hz sine wave (90 dB SPL for guinea pigs and 80 dB SPL for chinchillas), which evoked an equivalent magnitude of cochlear microphonics (CM) in both species, was used to modulate the compound action potential (CAP) and the summating potential (SP) elicited by 8-kHz tone bursts. Overall patterns of CAP and SP modulation were almost identical between the two species except for a difference in the phase of 50 Hz CM. The phase of maximum SP enlargement was in accord with that of maximum CAP suppression, which led to inferred basilar membrane (BM) position at maximum scala tympani displacement by between 45 and 90 degrees. More complex or hysteresis effects seemed to be involved in the modulation of CAP and SP magnitude, in addition to the biasing effect owing solely to BM displacement.

Abstract
We developed a device for odorous stimuli control to record olfactory evoked responses from the human scalp. The characteristics of the apparatus are as follows. Translating the subject's respiration into electric signals with a sensor attached to the nose. The period and timing of odorous stimuli could be adjusted, so that stimuli could be synchronous with respiration. The interstimulus interval could be arbitrarily selected once every 1 to 9 respiration(s) so that adaptation could be prevented. We obtained evoked responses to odorous stimuli using this apparatus from the human scalp, whose positive peak latencies were approximately 350 and 700 msec. Such responses were not recorded if oxygen stimuli were used instead of odorous stimuli or with click sounds produced by the switching electromagnetic valve. Three types of odorant evoked scalp potentials were obtained in normal human subjects. The first type consisted mainly of two positive peaks with a peak latency of about 350 msec (P350) and about 700 msec (P700). The second type and the third type consisted of only one positive peak with a peak latency of about 350 msec and 700 msec, respectively. Such a P350 or P700 peak as that observed in the normal subjects was not detected in anosmic patients.

Abstract
The scalp topography of binaural interaction (BI) in the auditory brainstem response (ABR) was studied in fourteen normal individuals. BI was observed from all recording sites of the scalp, and the peak amplitude was noted mostly in the bilateral parietal and occipital regions. There was a significant difference in amplitude shown by significance probability mapping (SPM) when the waveform obtained by binaural stimulation was compared with the sum of the waves obtained by monaural stimulation. The topography of BI was different from that of the wave III and the wave IV/V complex. In contrast to previous reports by other workers, we found that BI mainly corresponded to the first half of the wave IV/V complex.

Abstract
The auditory brainstem responses (ABRs) obtained from 28 normal healthy adults were studied using the ipsilateral and contralateral recordings from the positions of vertex and each mastoid to monaural stimulation. Each wave of ABRs recorded by ipsilateral and contralateral derivations to stimulation site showed slightly significantly differences. Comparing the ipsilateral and contralateral data, the latencies of waves II and V showed a slightly small reduction in the ipsilateral recording, while these of waves III and IV showed a small increase. Next, the distributions of potentials and latencies of waves II to V were investigated from ABRs situating different electrodes in mid-coronal array of the scalp and non-cephalic reference electrode on the seventh cervical vertebra (CVII). The results of latencies showed the reverse relation to the data obtained from the ipsilateral and contralateral recordings using the reference electrodes on each mastoid. These facts suggest that the comparable differences of latencies in the bilaterally recorded ABRs are explained by the pseudo-phenomena of differential recordings, which the phase delayed or advanced potential propagated to each mastoid being reference electrode position.

Abstract
Multiple myeloma is a malignant disease of the skeleton. Anatomically, any bone may ultimately come to be involved in a given case. In a literature review, no published series of temporal bone findings have been reported. In this study, oto-histopathologic changes associated with multiple myeloma are analyzed and reported in 15 temporal bones from 8 patients. The bone marrow of 13 temporal bones was involved by the tumor. Osteolysis was evident in 11 temporal bones. Serous otitis media (SOM) or purulent otitis media (POM) was seen in 13 ears with 12 showing mastoid effusions. Eight ears exhibited pathological changes in inner ears, including degeneration of the organ of Corti, atrophy of stria vascularis, decreased ganglion cells, and labyrinthine hydrops. The inner ear changes were most severe in 2 patients who had otologic symptoms. Infiltration of myeloma cells was not apparent in the middle ear mucosa or the inner ears.

Abstract
In spite of the wealth of information on the clinical, histologic, and pathologic aspects of tympanosclerosis, the pathogenesis of tympanosclerosis is still unclear. In an attempt to understand the pathogenesis, 319 human temporal bones from 196 individuals with otitis media were studied. The extent and nature of tympanosclerosis and the characteristics of the otitis media associated with it were studied. Forty-five temporal bones from 35 individuals with otitis media were found to have tympanosclerosis, giving an incidence of 14.1%. It was seen most commonly in individuals over 40 years of age (86.7%). The male-to-female ratio was 1.6:1. The most common site of occurrence was the tympanic membrane (88.9%). Tympanosclerosis was seen more often in the anterior and posterior inferior quadrants of the tympanic membrane and that, too, in a central position. Tympanosclerosis was seen more commonly in temporal bones with irreversible inflammatory changes, and in this group, late plaques were more commonly seen than early or intermediate plaques. Audiometric charts failed to show any direct relationship between extent of tympanosclerosis and the severity of hearing loss. The only audiometric finding of any consequence was a mixed hearing loss in the presence of middle ear tympanosclerosis.

Abstract
Histopathological findings in seven temporal bones from four infants diagnosed as Potter's syndrome are described. The infants were labelled as Potter's syndrome after autopsy confirmed bilateral renal agenesis. Extrarenal manifestations included pulmonary hypoplasia and facial anomalies. The middle ear volume in infants with Potter's syndrome remained unchanged with age resulting in a significantly higher percentage of residual middle ear mesenchyme in these infants as compared to normal infants. Dehiscence of the facial nerve was seen in all the temporal bones studied. One ear showed the presence of eosinophilic effusion in the endolymphatic sac, an underdeveloped malleus and a wide facial nerve canal. The inner ear structures showed no significant anomalies except for the absence of the organ of Corti in the basal turn of the cochlea in one of the ears.

Abstract
Three-component analysis of caloric nystagmus, focusing on the horizontal, vertical, and torsional, using a computerized eye movement analysis system, was carried out in 10 normal human subjects. The caloric response was induced by cold stimulation to the right ear of the subjects in the supine and prone positions. In the supine position, the three components of nystagmus were toward the left (10 subjects), upward (eight subjects) or downward (two subjects), and clockwise (10 subjects). In the prone position, on the other hand, the three components were directed toward the right (10 subjects), downward (five subjects), upward (three subjects), and counterclockwise (10 subjects); there was no vertical direction in two subjects. These findings indicate that caloric stimulation activates the three semicircular canals simultaneously. Also the changes in the nystagmus direction in the supine and prone positions could be explained, at least partially, by the nonconvective component of caloric stimulation.

Abstract
We have tested the hypothesis that the cause of cochlear dysfunction associated with perilymphatic fistula (PLF) is closely related to endolymphatic hydrops (ELH). Using guinea pigs, we studied the tone-burst elicited compound action potential (CAP) and its modulation as caused by a 50 Hz biasing tone in experimental PLF. We compared these results with those of experimental ELH. Following perilymph aspiration through the perforated round window membrane, mild but significant elevations of CAP thresholds at tested frequencies were found. A reduction in the amplitude of cochlear microphonics (CM) for a 50 Hz sine wave appeared to correlate with these CAP threshold changes. However, there were no significant changes in the modulation effect of the 50 Hz biasing tone on the CAP elicited by an 8 kHz tone burst. This finding differed from that in ears with experimental ELH, in which significant reductions of both 50 Hz CM and the degree of CAP modulation were consistently observed. We concluded that it is unlikely that the underlying mechanisms of a modification to the low frequency response of the base of the cochlea following perilymph aspiration is linked to that of experimental ELH.

Abstract
By the use of computer-assisted morphometric analysis of the organ of Corti and/or measurements of action potential threshold changes, inner ear changes in chinchillas were evaluated 4 weeks after application on the round window membrane of a Pseudomonas aeruginosa exotoxin A solution. Severe inner ear damage was detected after application of 50 ng (5 microL at a concentration of 10 micrograms/mL) exotoxin A, whereas application of 5 ng exotoxin did not cause measurable inner ear damage. Perilymph concentrations of exotoxin A were measured with an enzyme-linked immunosorbent assay 1.5 to 19 hours after 50 ng, 0.5 micrograms, or 5 micrograms of exotoxin A was applied on the round window membrane. Only the highest concentration produced measurable levels of exotoxin in the inner ear fluids. It is concluded that exotoxin A present on the round window membrane of the chinchilla has the ability to penetrate into the inner ear and cause irreversible inner ear changes.

Abstract
Bestron, a new otic preparation containing cefmenoxime, was applied to the round window membrane of the chinchilla and the long-term cochleotoxicity was evaluated by means of electrocochleography. The thresholds of the compound action potential (CAP) in all frequency areas tested ranged within normal values. The input-output and -latency relationships of the CAP resulted in no significant deterioration of hearing. However, identical treatment with Cortisporin resulted in elevated CAP threshold in the high frequency area and deterioration of the input-output and -latency of the CAP. These findings indicate that Bestron is noncochleotoxic as compared with Cortisporin and therefore may be used safely in the treatment of infected ears.

Abstract
Sensorineural hearing loss (SNHL) has been documented in patients with otitis media. Despite a number of clinical and pathologic works dealing with this common problem, animal studies searching for possible relationships between the middle ear inflammation and cochlear function remain insufficient. Bacterial inoculation and ototoxins and inflammatory products in the middle ear cavity cause SNHL in rodents. Human serum albumin placed in the middle ear cavity in chinchillas also produces SNHL, owing to the effects of nonspecific inflammation in the middle ear cavity. Most of the middle ear inflammatory mediators enter the inner ear through the round window route, and alteration of the permeability of the round window membrane plays an important role in causing cochlear dysfunction. Although an immunologic response in the middle ear plays an important role in otitis media, the immunologic response in the inner ear as it relates to middle ear inflammatory mediators requires further study.

Abstract
To investigate the influence of the cervical input to the equilibrium, the effect of neck vibratory stimulation on body sway was analyzed in 49 normal human subjects. Body perturbations during standing posture were recorded by a force platform with or without vibratory stimulus on the upper cervical region, and analyzed by computer. During the neck vibratory stimulation, the center of gravity was shifted to the forward, and the amplitude of the body sway was increased especially along the front-rear axis. These results indicate that the proprioceptive inputs from the cervical receptors largely modifies the body equilibrium in normal subjects.

Abstract
The ionic composition of the endolymph in the endolymphatic sac (ES) of the chinchilla was measured using double-barreled ion-selective micro-electrodes. The DC potential of the ES was 9.3 +/- 1.8 mV (N = 18). The K+, Na+, and Cl- concentrations of the ES were 13.3 +/- 4.7 mM (N = 6), 129.0 +/- 8.8 mM (N = 6), and 124.3 +/- 16.6 mM (N = 6), respectively. In light of the chemical potentials of the cochlear endolymph previously reported [Ikeda and Morizono (1989), Hear. Res., 39, 279-286] the pressure gradient of the endolymph between the cochlea and ES was calculated to be 71.5 mmHg at 38 degrees C. The contribution of the osmotic and hydrostatic pressure gradients of the endolymph to the longitudinal flow is discussed.

Abstract
The ototoxicity of the corticosteroid triamcinolone diacetate was investigated using the compound action potential (CAP) of the auditory nerve as a parameter when the drug was applied to the middle ear cavity of the chinchilla. Comparison with the contralateral ear, instilled with Ringer's solution, demonstrated no significant difference in the threshold, amplitude, and latency of the CAP responses at the overall frequencies tested. In addition, the side difference of the CAP threshold in individual animals showed that this corticosteroid did not induce cochlear dysfunction in any case.

Abstract
Ionic activities (K+, Na+, and Cl-) of the perilymph and endolymph of the basal turn were measured using ion-selective microelectrodes in experimentally induced endolymphatic hydrops of the guinea pig. Three months following the obstruction of the endolymphatic duct and sac, the endocochlear potential (EP) of hydroptic ears was measured at 59.7 +/- 9.6 mV (N = 12) which was significantly lower than the EP of the contralateral control ears (84.4 +/- 2.8 mV, N = 12). A paired t-test (P greater than 0.05) showed no significant differences of ion concentrations of the inner ear fluid between the hydroptic and contralateral ears. Ion permeabilities of the cochlear duct following anoxia were calculated according to the Nernst-Planck equation. Comparing hydroptic and normal ears following anoxia, a statistically significant decrease was observed in the permeability coefficients for K+. Similarly, K+ conductance was significantly lower in the hydroptic ears than in the normal ears. Total conductance of the cochlear duct, defined as the sum of each ion conductance, was 0.560 siemens in the normal ears and 0.217 siemens in the hydroptic ears. On the basis of the Goldman-Hodgkin-Katz equation, preexisting negative EP in the normal state was calculated to be -24.5 mV in normal ears and -21.4 mV in hydroptic ears. Therefore, the positive component of the EP was 108.9 mV in normal ears and 81.1 mV in hydroptic ears. These findings suggest that the pathophysiology of hydrops involves changes in K+ permeability and the inhibition of the electrogenic transport processes.

Abstract
Maintenance of homeostasis of inner ear fluids and biochemical integrity of inner ear tissue are essential for proper functioning of the auditory and vestibular end organs. Although various regulatory mechanisms exist in a different portion of the labyrinth, the inner ear is known to respond to systemic challenges. The association of Meniere's syndrome with an imbalance of inner ear fluid homeostasis has been hypothesized for the past century. Among many factors, the effects of hormonal imbalance on inner ear fluid composition and inner ear function have however scarcely been studied. The purpose of this study was to explore the relationship between the autonomic nervous system and inner ear function and possible mechanisms of functional disturbances in an experimental condition. An infusion of supraphysiologic amounts of epinephrine, a stress related hormone, resulted in an elevation of osmolality in serum and perilymph. Furthermore, the infusion of epinephrine resulted in elevation of threshold, prolongation of latency, and depression of amplitude in the compound action potential of the auditory nerve. These findings were most marked at high frequencies. We hypothesized that the epinephrine-induced hearing loss was brought about by an increase in perilymphatic osmolality, as well as by the ionic imbalance caused by the osmotic gradient. Since emotional stress has been implicated as a mechanism of inducing a Meniere's attack, evaluation of the relationship between the autonomic system and cochlear function may contribute to the understanding of possible mechanisms of inner ear dysfunction caused by hormonal imbalances.

Abstract
The effects of topical otic preparations (Cortisporin, Coly-Mycin, Aristocort, and Bestron) upon the permeability of the round window membrane (RWM) in chinchillas were investigated. Using K(+)-selective microelectrodes, the concentration of tetraethylammonium (TEA) ions was measured. Changes in the thickness of the RWM were measured using light microscopy. The RWM permeability was reduced significantly in Cortisporin- and Coly-Mycin-treated ears. Moreover, these two drugs resulted in a marked thickening of the RWM. In contrast, Aristocort or Bestron resulted in no alteration of the RWM permeability.

Abstract
It is important to be aware of the potential ototoxicity of any drug, vehicle, or antiseptic that is used in the middle ear. Frequently used ear drops (Cortisporin otic suspension, Coly-Mycin S Otic, and VoSoL otic solution) were studied for their ototoxicity. Compound action potentials were measured before and at 1, 2, and 24 hours following drug application on the round window membranes of chinchillas. Each drug was applied for 10 minutes and then was removed by rinsing. The sound pressure in decibels sound pressure level that produced a compound action potential amplitude of 10 microV was defined as the threshold. The change in threshold was interpreted as hearing loss. On the basis of the short-term results at 24 hours following drug application, the ototoxicity of Coly-Mycin was calculated to be twice that of Cortisporin, and the ototoxicity of VoSoL four times that of Cortisporin.

Abstract
Round window membrane (RWM) permeability is the most critical factor influencing cochlear function following otitis media. Because otic drops are frequently used during purulent otitis media (POM), we investigated RWM permeability and ototoxicity of Cortisporin otic suspension after inducing experimental POM. Unilateral POM was induced in eight chinchillas by inoculating type 7F Streptococcus pneumoniae into the right ears. Left ears were inoculated with phosphate-buffered saline (control). When POM resolved, the animals were divided into two groups. The round window niches of group 1 were covered with Cortisporin otic suspension. Compound action potentials were measured before and after drug application. The RWM permeability was measured in group 2 by use of tetraethylammonium (TEA) ions as tracers, and the arrival time of TEA and the slope of the potassium-selective microelectrode response were measured. Animals with otitis media exhibited less susceptibility to ototoxicity of Cortisporin otic suspension and reduced RWM permeability to the medium-sized molecule TEA.

Abstract
A new technique for an eye movement analysis system utilizing infrared video recording and a computerized image recognition method is presented. The system consists of an infrared lighting apparatus, a very small infrared video charge-coupled device camera, a video tape recorder, an analogue-digital converter, and microcomputers. This system makes it possible to simultaneously analyze the slow-phase velocity quantitatively not only of the horizontal and vertical but also of the rotatory components of the energy-induced nystagmus. The maximum slow-phase velocity of the rotatory component of energy-induced nystagmus was found to be 4.1 degrees per second on an average in this study.
