Abstract
We measure the energy emitted by extensive air showers in the form of radio emission in the frequency range from 30 to 80 MHz. Exploiting the accurate energy scale of the Pierre Auger Observatory, we obtain a radiation energy of 15.8±0.7(stat)±6.7(syst) MeV for cosmic rays with an energy of 1 EeV arriving perpendicularly to a geomagnetic field of 0.24 G, scaling quadratically with the cosmic-ray energy. A comparison with predictions from state-of-the-art first-principles calculations shows agreement with our measurement. The radiation energy provides direct access to the calorimetric energy in the electromagnetic cascade of extensive air showers. Comparison with our result thus allows the direct calibration of any cosmic-ray radio detector against the well-established energy scale of the Pierre Auger Observatory.

Abstract
QBP359 is an IgG1 human monoclonal antibody that binds with high affinity to human CCL21, a chemokine hypothesized to play a role in inflammatory disease conditions through activation of resident CCR7-expressing fibroblasts/myofibroblasts. The pharmacokinetics (PK) and pharmacodynamics (PD) of QBP359 in non-human primates were characterized through an integrated approach, combining PK, PD, immunogenicity, immunohistochemistry (IHC) and tissue profiling data from single- and multiple-dose experiments in cynomolgus monkeys. When compared with regular immunoglobulin typical kinetics, faster drug clearance was observed in serum following intravenous administration of 10 mg/kg and 50 mg/kg of QBP359. We have shown by means of PK/PD modeling that clearance of mAb-ligand complex is the most likely explanation for the rapid clearance of QBP359 in cynomolgus monkey. IHC and liquid chromatography mass spectrometry data suggested a high turnover and synthesis rate of CCL21 in tissues. Although lymphoid tissue was expected to accumulate drug due to the high levels of CCL21 present, bioavailability following subcutaneous administration in monkeys was 52%. In human disease states, where CCL21 expression is believed to be expressed at 10-fold higher concentrations compared with cynomolgus monkeys, the PK/PD model of QBP359 and its binding to CCL21 suggested that very large doses requiring frequent administration of mAb would be required to maintain suppression of CCL21 in the clinical setting. This highlights the difficulty in targeting soluble proteins with high synthesis rates.

Abstract
Energy-dependent patterns in the arrival directions of cosmic rays are searched for using data of the Pierre Auger Observatory. We investigate local regions around the highest-energy cosmic rays with [Formula: see text] eV by analyzing cosmic rays with energies above [Formula: see text] eV arriving within an angular separation of approximately 15[Formula: see text]. We characterize the energy distributions inside these regions by two independent methods, one searching for angular dependence of energy-energy correlations and one searching for collimation of energy along the local system of principal axes of the energy distribution. No significant patterns are found with this analysis. The comparison of these measurements with astrophysical scenarios can therefore be used to obtain constraints on related model parameters such as strength of cosmic-ray deflection and density of point sources.

Abstract
We report a measurement of the proton-air cross section for particle production at the center-of-mass energy per nucleon of 57 TeV. This is derived from the distribution of the depths of shower maxima observed with the Pierre Auger Observatory: systematic uncertainties are studied in detail. Analyzing the tail of the distribution of the shower maxima, a proton-air cross section of [505±22(stat)(-36)(+28)(syst)] mb is found.

Abstract
OBJECTIVE Hypnotherapy is currently used for tinnitus therapy in our university hospital. The aim of this study was to evaluate its efficacy. MATERIAL AND METHODS This study was performed on 110 patients suffering from distressing tinnitus. They were treated during five sessions with hypnotherapy, supplemented by instruction on self-hypnotherapy. A subjective evaluation was done by the practitioner at the end of the sessions of hypnotherapy. Then a questionnaire on psychologic distress (Wilson 1991) was sent retrospectively to the patients. RESULTS We received 65 responses which were used for this study. Before treatment, the mean value of the Wilson score was 54 (28-104). After treatment, it was: 31 (0-86). 69% of the patients felt an improvement > or = 5 points Wilson score. These results were compared with the evaluation carried out by the practitioner at the end of the sessions of hypnosis. There was a "significant correlation" between the evaluation of the felt benefice, analyzed by the practitioner at the end of the sessions of hypnosis, and by the patient questioned long after the treatment. These results had significant correlation with the evaluation made by the therapist at the end of the five sessions of hypnotherapy. They show, how effective (68% improvement) this therapeutic approach can be. CONCLUSION Hypnotherapy can be regarded as an effective treatment against distressing tinnitus.

Abstract
We describe the measurement of the depth of maximum, X{max}, of the longitudinal development of air showers induced by cosmic rays. Almost 4000 events above 10;{18} eV observed by the fluorescence detector of the Pierre Auger Observatory in coincidence with at least one surface detector station are selected for the analysis. The average shower maximum was found to evolve with energy at a rate of (106{-21}{+35}) g/cm{2}/decade below 10{18.24+/-0.05} eV, and (24+/-3) g/cm{2}/decade above this energy. The measured shower-to-shower fluctuations decrease from about 55 to 26 g/cm{2}. The interpretation of these results in terms of the cosmic ray mass composition is briefly discussed.

Abstract
REASONS FOR PERFORMING STUDY Perineural analgesics are used for lameness diagnosis but the duration of effect, knowledge of which would provide valuable information when performing subsequent blocks, is unknown. OBJECTIVE To evaluate the duration of a palmar digital nerve block using force plate measurements. METHODS Ten horses diagnosed with unilateral navicular syndrome were trotted at range of 3 +/- 0.15 m/sec over a force plate to record ground reaction forces for 5 trials of each forelimb. Data were recorded before nerve block, and then at 15 mins, 1, 2 and 24 h post nerve block. RESULTS Before nerve block, peak vertical force (mean +/- s.e.) was significantly higher in the contralateral forelimb (CL = 5345 +/- 188 N) than in the lame forelimb (L = 4256 +/- 204 N; P<0.05). At 15 mins post nerve block there was no significant difference between the 2 forelimbs (CL = 5140 +/- 184 N; L = 5126 +/- 129 N), and this remained the case for 1 h. By 2 h, the mean score for the lame leg had decreased (L = 4642 +/- 182 N) but was still greater than preblock. By 24 h, vertical forces had returned to preblock values. CONCLUSIONS The palmar digital nerve block was fully effective between 15 mins and 1 h. The analgesic effect began to subside between 1 and 2 h but sufficient analgesia persisted to affect gait characteristics beyond 2 h. POTENTIAL RELEVANCE When using a palmar digital nerve block, it is important to perform lameness evaluations between 15 mins and 1 h to be sure of effective nerve blockade.

Abstract
Facial locoregional anesthetics (ALR) with nervous blocks are simple and reliable to perform, need little technical resources with a very low iatrogenic risk. These blocks allow anesthesia without deforming wound banks using the same materials as usual local anesthetic procedures. Three principal nervous blocks, in a straight line along the vertical pupil axis, allow managing - even extensive - facial wounds. Few side effects may occur which can be easily prevented. It is a good alternative to local anesthetic for the treatment of extensive and deep areas which is performed with a lower number of injections and a high rate of success. These techniques are easy to learn and practise. These anesthetic techniques allow a nice treatment of different kinds of facial wounds from simple suture to flaps.

Abstract
The energy spectrum of cosmic rays above 2.5 x 10;{18} eV, derived from 20,000 events recorded at the Pierre Auger Observatory, is described. The spectral index gamma of the particle flux, J proportional, variantE;{-gamma}, at energies between 4 x 10;{18} eV and 4 x 10;{19} eV is 2.69+/-0.02(stat)+/-0.06(syst), steepening to 4.2+/-0.4(stat)+/-0.06(syst) at higher energies. The hypothesis of a single power law is rejected with a significance greater than 6 standard deviations. The data are consistent with the prediction by Greisen and by Zatsepin and Kuz'min.

Abstract
The surface detector array of the Pierre Auger Observatory is sensitive to Earth-skimming tau neutrinos that interact in Earth's crust. Tau leptons from nu(tau) charged-current interactions can emerge and decay in the atmosphere to produce a nearly horizontal shower with a significant electromagnetic component. The data collected between 1 January 2004 and 31 August 2007 are used to place an upper limit on the diffuse flux of nu(tau) at EeV energies. Assuming an E(nu)(-2) differential energy spectrum the limit set at 90% C.L. is E(nu)(2)dN(nu)(tau)/dE(nu)<1.3 x 10(-7) GeV cm(-2) s(-1) sr(-1) in the energy range 2 x 10(17) eV< E(nu)< 2 x 10(19) eV.

Abstract
Using laser Doppler flowmetry, cochlear blood flow was assessed in Mongolian gerbils exposed to noise. Anesthetized animals were surgically implanted with permanent electrodes and then exposed for 10 consecutive days (6 h on/18 h off) to an octave band noise centered at 4 kHz (85 dB SPL). The auditory brainstem responses and the blood flow in the basal turn of the cochlea were compared with those of gerbils not exposed to noise. The exposed animals developed an initial threshold shift, followed by a progressive reduction in threshold shift up to complete recovery at the end of the test. In the exposed animals, a reduction in the cochlear blood flow during the first 4 days of exposure was observed, which was then followed by a progressive increase up to the end of the test. The results of this study exclude a possible role of the microvasculature of the lateral cochlear wall in determining the resistance to 4 kHz frequency noise exposure.

Abstract
The approach to chronic toxicity testing over the past decade is reviewed and assessed in the light of developing ICH guidelines. The 1990's have seen a general acceptance that studies with a maximal duration of 6 months in rodents are all that is required for adequate safety assessment of developmental pharmaceutical agents. However, controversy has arisen concerning the most appropriate duration for chronic toxicity testing in non-rodents. Initial suggestions that 6 months duration was sufficient have been countered by findings noted in 12-month studies that were not seen in shorter-term studies. Retrospective analysis of available data eventually lead to a subsequent ICH recommendation that studies of 9 months duration would be now acceptable. However, until recently the FDA position on this recommendation was unclear and an analysis of industry practices since the ICH recommendation was made in 1997 has shown that the 9-month guideline is not widely applied. Recent clarification by the FDA will probably result in a continued but limited use of this alternative. An industry view on the future of chronic toxicology testing in rodents and non-rodents is presented.

Abstract
In acute myeloid leukemia (AML) patients, a variety of clinical and biologic parameters, including phenotype, have been examined for potential value in predicting treatment response and survival. The European Group for the Immunological Classification of Leukaemias (EGIL) has proposed that AML be defined immunologically by the expression of 2 or more of the following myeloid markers: myeloperoxidase, CD13, CD33, CDw65, and CD117. With regard to this classification, the prognostic significance of 21 antigens taken separately and with immunophenotypic subgroups were evaluated and compared with other clinical and biological variables in 177 adult AML patients. None of the antigens tested were associated with treatment outcome. In contrast, patients with blasts disclosing a full expression of panmyeloid phenotype (defined by the expression of all 5 myeloid markers) had a higher complete remission rate (P <. 0001) and differed significantly in disease-free survival (P =.02) and overall survival (P =.008) than patients whose cells expressed fewer than 5 of these markers. In multivariate analysis, only age, panmyeloid phenotype, performance status, and permeability glycoprotein activity influence treatment outcome. Cytogenetics was significant in univariate analysis but not in multivariate analysis, most likely because of the redundancy with panmyeloid phenotype and a higher sensitivity of immunophenotyping. Patients whose cells exhibit the panmyeloid phenotype appear to define a relatively homogeneous biological subset of AML. The 4 independent prognostic factors were used to create a prognostic score, defined by the number of factors present. This score permitted a stratification of patients with AML, thereby allowing for the consideration of innovative therapies to improve outcome in the poorer outcome groups.

Abstract
The main goal of the present study was to investigate the response of the human skin equivalent Apligraf in vitro to the application of irritant substances and its predictivity as a screening tool for cumulative skin irritant potential in humans. Vaseline, calcipotriol, trans-retinoic acid, and sodium lauryl sulfate were applied to Apligraf in vitro for 24 h. Cell viability (lactate dehydrogenase leakage), release and mRNA expression of the proinflammatory cytokines IL-1alpha and IL-8, and morphological changes were assessed. The same products were applied to 30 healthy volunteers in a double-blind, randomized, vehicle-controlled within-subject study. The skin reactions after repeated 24-h applications over 3 weeks under Finn chamber patches were monitored by visual scoring and biophysical methods (trans-epidermal water loss, chromametry, and blood flow). Sodium lauryl sulfate was cytotoxic to Apligraf, and increased the release and expression of cytokines at low (0.2%, 0. 4%), but not at high (0.8%, 1%) concentrations. It induced severe irritancy in vivo. Trans-retinoic acid increased the expression and release of cytokines with no detectable cytotoxicity and showed moderate irritancy in humans. Although calcipotriol did neither affect cell viability nor the production of cytokines, it induced morphological signs of irritation and was mildly irritant for healthy volunteers. Vaseline was innocuous in vivo and induced no changes in Apligraf. In conclusion, the cumulative skin irritation potential of the tested products could be predicted with Apligraf in a sensitive and specific manner, by monitoring cytotoxicity, proinflammatory cytokines, and morphological changes.

Abstract
For the development of mechanistic assays in immunotoxicology, the phenotype, cytokine production, and stimulatory function of dendritic cells (DCs) were assessed after incubation with the chemical haptens aminophenol, chlorpromazine hydrochloride, dinitrochlorobenzene (DNCB), and with the DNCB-corresponding tolerogen DCNB, the metal allergen nickel sulfate, the irritants sodium dodecyl sulfate and benzoic acid, as well as with staphylococcal enterotoxin B (SEB) and lipopolysaccharide (LPS). DCs were differentiated from human monocytes by in vitro exposure to GM-CSF and interleukin-4 (IL-4) for 7 days. Flow cytometric data revealed that only representative haptens increased the surface expression of HLA-DR, CD86, CD40, and of CD54 on DCs when compared to irritants or to the tolerogen. This event was associated with an increased ability of DCs to stimulate T cell proliferation. Moreover, after incubation with the haptens, but not with the irritants or the tolerogen, a higher production of TNF-alpha by DCs was observed. Under our experimental conditions, no release of IL-1beta, IL-10, or IL-12 was detected. Compared to the activation elicited by haptens, SEB strongly up-regulated HLA-DR and costimulatory molecule expression. In agreement with this effect, there was a marked release of TNF-alpha and a slight production of IL-12. IL-1beta and IL-10 were not detected in the culture medium. Finally, SEB-pulsed DCs showed a strong T-cell-stimulating activity. These data underline the activating potential of haptens versus irritants or a tolerogen on DC functions. The different levels of DC activation by haptens and SEB suggested that distinct cellular events were involved.

Abstract
The aim of the present study was to confirm the hypothesis that the cochlear efferent system is involved in the mechanisms underlying the "toughening" effect at high frequencies. The toughening effect is defined as a progressive threshold shift reduction when repeated exposures to the same noise are applied. Vestibular neurectomy was performed through a posterior cranial fossa approach in six healthy pigmented guinea pigs, and it assured the interruption of both crossed and uncrossed olivocochlear bundles to one ear only, before their entrance in the internal auditory meatus. The animals were then implanted with permanent electrodes for the electrocochleographic findings. Ten days after the operation the animals were exposed to octave-band toughening noise, centered at 4 kHz, at 85-dB SPL, for 10 consecutive days, 6 hours on/18 hours off. The hearing threshold was registered before and at the end of each exposure session. The behavior of the hearing threshold in the operated ears was then compared to that of the controlateral, nonoperated ears. Complete recovery from TS in the control ear began after four days of exposure, whereas in the operated ear hearing loss increased to day 7 (55 dB), with only a partial reduction (45 dB) beyond ten days of exposure. The results of the present study clearly demonstrated that sectioning of the OCB in guinea pigs causes persistent hearing loss during noise-exposure conditioning, in comparison to the contralateral, nonoperated ear. Thus, one can assume that the lack of decrease of TS during intermittent noise exposure could be due to the loss of the protective effect of the efferent fibers, perhaps mediated by the lateral OC neurons that synapse beneath the IHCs.

Abstract
The immunosuppressive drug, cyclosporin A (CsA), which is successfully used to prevent rejection in organ transplantation, induces renal side-effects as shown by a decrease in glomerular filtration rate and ultrafiltration coefficient regulated by the tone of mesangial cells.The aim of the present study was to investigate the effect of CsA on isolated glomeruli and mesangial cells, which constitute appropriate in vitro models for renal vasoreactivity studies. The roles of different intracellular and extracellular mediators such as calcium, endothelin-1 (ET-1), prostaglandins (TXA(2 )and PGI(2)) and reactive oxygen intermediates (ROIs) were analysed. CsA caused a concentration- and time-dependent decrease in the planar cross-sectional areas of isolated glomeruli and mesangial cells as determined by image analysis. Intracytosolic free calcium concentration determined by fluorimetric analysis was significantly increased after 30 min CsA (10 microM) incubation. In the contraction experiment, the calcium antagonist verapamil inhibited the CsA response. ET-1, TXB(2) and keto-PGF(1alpha) were determined directly, however no changes were found statistically significantly different from respective controls. In contrast to these results, the ET-1 specific antibody was able to reduce CsA-mediated cell contraction. In the presence of a prostacyclin agonist iloprost, CsA-induced contraction was also modified. The role of ROIs using a 2'7'-dichlorofluorescein diacetate (DCFdAc) fluorimetric method was directly determined by observing, with 10 microM CsA, a significant production of hydrogen peroxide (H(2)O(2)), which was able alone to induce mesangial cell contraction. Coincubation with the antioxidants led to a significant inhibition of mesangial cell contraction. These results suggest that CsA caused an imbalance in the normal level of all investigated vasoconstrictive and vasodilator mediators, which shifted towards the advantage of vasoconstrictive action.

Abstract
Administration of antiasthmatic drugs in the form of inhalation particles may alter the cytokine network in the airways, independently of their pharmacological actions. Changes induced by drugs not well tolerated may potentially contribute to the immunopathology of the disease, a strongly undesirable effect. In this study, cell viability assays and characterization of the cellular profile of cytokines and chemokines were performed in order to investigate the response of human bronchoalveolar macrophages and bronchial epithelial cells in culture to inhalation particles of the cyclosporine derivative IMM 125. Interleukin 1beta (IL-1beta), tumor necrosis factor alpha (TNFalpha), and IL-8 were assayed by enzyme-linked immunosorbent assay (ELISA) in the supernatants of bronchoalveolar macrophages, and RANTES, granulocyte--macrophage colony-stimulating factor (GM-CSF), and IL-8 in those of bronchial epithelial cells. Cells were studied both under basal and stimulated conditions (lipopolysaccharide and TNFalpha were used for activating macrophages and epithelial cells, respectively). The immunosuppressant FK 506 and the glucocorticoid Budesonide served as comparison. IMM 125 did not affect cell viability (except at high concentrations and long time periods). Moreover, IMM 125 did not induce an increase in the secretion of any of the cytokines and chemokines measured with respect to nontreated cells, except for a slight increase in IL-8, an effect that was also observed for FK 506, Budesonide, and inert latex particles, and was therefore regarded as nonspecific. Furthermore, IMM 125 significantly decreased the secretion of TNFalpha, IL-1beta by macrophages, and GM-CSF by epithelial cells, suggesting an antiinflammatory potential. In conclusion, the present in vitro results point to a good tolerance of human airways to IMM 125 inhalation particles.

Abstract
The cyanelle of the primitive alga Cyanophora paradoxa is the only photosynthetic organelle where the ribonucleoprotein nature of ribonuclease P has been functionally proven. To increase our knowledge about RNA structure and overall composition of this enzyme, we have now determined relevant physical parameters and performed RNA accessibility experiments. Buoyant density and relative molecular mass of cyanelle RNase P were more similar to the eukaryotic (nuclear or mitochondrial) than to the bacterial enzyme type, despite the close phylogenetic relationship between plastids and cyanobacteria. Enzymatic and chemical probing was used to establish the secondary structure of cyanelle RNase P RNA. The results obtained with the naked transcript support the previously proposed, phylogenetically derived structure. Probing of the RNA in the holoenzyme resulted in reduced sensitivity at a large number of positions, indicating that these regions might be located in the interior of the ribonucleoprotein. Protection of the RNA in cyanelle RNase P was more extensive than reported for the Escherichia coli holoenzyme, but similar to the pattern observed in yeast nuclear RNase P. Taken together, these results indicate that the protein contribution in cyanelle RNase P is much larger than in the bacterial enzymes, and that the overall composition of the holoenzyme resembles that found in eukaryotes.

Abstract
An immunochromatographic 1-step test for the detection of fecal occult blood was evaluated for applicability for the forensic identification of human blood in stained material. The following experiments were conducted: 1) determination of the sensitivity and specificity of the assay; 2) evaluation of different extraction media for bloodstains (sterile water, Tris buffer pH 7.5 provided in the test kit, 5% ammonia); 3) analysis of biological samples subjected to a variety of environmental insults; and 4) evaluation of casework samples. This immunochromatographic 1-step occult blood test is specific for human (primate) hemoglobin and is at least an order of magnitude more sensitive than previous methods for detecting human hemoglobin in bloodstains. The antigen is insensitive to a variety of environmental insults, except for exposure to certain detergents and household bleaches and prolonged exposure to certain preparations of luminol. The entire assay can be conducted in field testing conditions within minutes. When in the laboratory the supernatant from a DNA extraction is used for the assay, there is essentially no consumption of DNA for determining the presence of human hemoglobin in a forensic sample. The data demonstrate that this test is robust and suitable for forensic analyses.

Abstract
An in vitro human reconstructed epidermis model (SkinEthic) used for screening acute and chronic skin irritation potential was validated against in vivo data from skin tolerability studies. The irritation potential of sodium lauryl sulfate (SLS), calcipotriol and trans-retinoic acid was investigated. The in vitro epidermis-like model consists of cultures of keratinocytes from human foreskin on a polycarbonate filter. The modulation of cell viability, the release and gene expression of proinflammatory cytokines, interleukins 1alpha and 8, and morphological changes were evaluated during 3 days as endpoints representative for an inflammatory reaction. The cumulative irritation potential of the topical products was evaluated in a human clinical study by visual scoring and biophysical measurement of inflammatory skin reaction after repeated 24 h applications over 3 weeks under Finn chamber patches. All topical products that were nonirritating in the human study were noncytotoxic and did not induce cytokine expression in the in vitro acute model (day 1 exposure). All irritating controls exhibited specific cell viability and cytokine patterns, which were predictive of the in vivo human data. The ranking of mild to moderate skin irritation potential was based on the lack of cytotoxicity and the presence of cytokine patterns including gene expression specific for each irritant, using the chronic in vitro model (up to 3 days exposure). The human reconstructed epidermis model SkinEthic was shown to be a reliable preclinical tool predicting the irritation potential of topical products. Moreover, it is a useful model in a two-step tiered strategy for screening acute and chronic irritation potential for the selection of vehicles for new topical drugs.

Abstract
In order to develop an in vitro predictive assay for the detection of contact sensitizers, we investigated the possible modulation of the expression of cell-surface molecules in the early phases of treatment of murine epidermal cells (EC) with known contact sensitizers. After in vitro treatment of Balb/c EC with the strong contact sensitizer, TNBS, Langerhans cells (LCs) demonstrated a rapid up-regulation of CD45, CD40, CD32/16 (Fc gamma RII/III) and CD23 (Fc epsilon RII) molecules. CD45 and CD40 were also rapidly up-regulated on the dendritic epidermal T cells. Interestingly, after treatment with this severe sensitizer, a marked induction of CD40 expression was found on a CD45 negative population, most probably keratinocytes. In contrast to these cell-surface molecules, I-Ad/I-Ed and CD90.2 expression were unchanged. No change was observed on the expression of CD45 and CD40 after treatment with a mild or a weak contact sensitizer, citral and citronellal respectively. In contrast, like TNBS, they up-regulated the expression of CD32/16 and CD23 on LCs. The irritant sodium dodecyl sulfate had no effect on all these cell-surface molecules. Our results indicated that in vitro, chemicals with allergic potential induced early specific phenotype changes that may represent an early-activated state of the cells. This state may be responsible for initiating the afferent phase of contact sensitivity in vivo. Based on these findings, it might be possible to develop an in vitro assay to reduce the number of experimental animals for a fast screening of contact sensitizers and for discriminating between mild contact sensitizers and irritants.

Abstract
SDZ PGU 693 acts as a hypoglycemic agent by stimulating glucose utilisation in insulin-sensitive peripheral tissues, such as skeletal muscle and fat. In a 28 day toxicity study the compound was found to induce hepatocellular hypertrophy in Wistar rats treated with 300 mg/kg/day. To gain insights into the pathomechanism of these alterations, aliquots of liver samples from control and treated female Wistar rats were separated by two-dimensional protein gel electrophoresis and the digitized images of the protein patterns were searched for protein abundance changes. Significant treatment-related quantitative changes (P < 0.001) were found in 29 liver proteins. Major increases were observed in several microsomal proteins, including NADPH cytochrome P-450 reductase, cytochrome b5 and serine protease inhibitor. The changes in the cytochrome related enzymes, both known co-factors of the P-450 enzyme system, strongly suggest that SDZ PGU 693 induces microsomal proliferation and induction of the P-450 enzyme system. Decreases were observed in a series of mitochondrial proteins, such as F1ATPase-delta subunit and ornithine aminotransferase precursor as well as in several cytosolic proteins such as the liver fatty acid binding protein, arylsulfotransferase and the senescence marker protein-30. The changes in F1ATPase-delta subunit and liver fatty acid binding protein together suggest a down-regulation of the mitochondrial liver fatty acid metabolism, likely reflecting the pharmacological action of the compound. These results show that SDZ PGU 693 produces a complex pattern of gene expression changes which give insights into the molecular mechanisms of both its pharmacological action and a toxic response.

Abstract
The aim of this study was to compare two types of cyclosporin (Cs) particles, SDZ OXL 400 and SDZ IMM 125, the latter being more hydrophilic, to understand their uptake by airway macrophages. Alveolar macrophages (AM), harvested by bronchoalveolar lavage (BAL) of hamster lungs, were cultured with two different doses (0.1 mg and 0.5 mg) for 1 h, 6 h, and 24 h. Control incubations without Cs particles or with latex particles were carried out simultaneously. Cell viability, cell activation (i.e., respiratory burst, interleukin-6 (IL-6) synthesis) and mean volume of particles phagocytosed per macrophage were measured. Both types of Cs particles did not modify the AM viability, and failed to induce IL-6 synthesis during phagocytosis but slightly decreased the cell oxidative respiratory burst. The comparison between SDZ OXL 400 and SDZ IMM 125 showed that for the lower dose the mean volume of both Cs types phagocytosed was similar at 1 h and 6 h. At 24 h an increase of the mean volume phagocytosed was seen for SDZ IMM 125 but not for SDZ OXL 400. For the higher dose the mean volume of SDZ IMM 125 phagocytosed was higher than SDZ OXL 400 at 1 h and 6 h and comparable for both types at 24 h. SDZ IMM 125 particles were phagocytosed more rapidly than SDZ OXL 400. The mean volume of phagocytosed latex particles increased with time and dose and was higher than for both Cs particle types. In conclusion, AM were seen to phagocytose particles of different physical properties (i.e., form, size, and shape), chemical properties (i.e., inert or peptidic) and degrees of hydrophilicity in a different manner.

Abstract
As it has been demonstrated in many animal experiments, noise can damage the cochlea and the central auditory pathways. It is very difficult in clinical studies to separate the relative contribution of both these sites. Auditory evoked potentials ABR, MLR and SVR study retrocochlear nervous conduction and collectively the results of these techniques proved an objective evaluation of the cochlear function. The Authors have studied a group of 130 sport shooters with high frequency hearing loss and found that in 38 ears a clear retrocochlear component could be recognised. Correlation with intensity, frequency and length of exposure to the traumatic noise demonstrates that explosive noise is an agent for NIHL. However athletes exposed to similar noises did not suffer from similar hearing loss, probably because of the well known individual noise susceptibility.

Abstract
The novel immunosuppressive drug O-hydroxyethyl-D(Ser)8-cyclosporine (SDZ IMM 125) and cyclosporine A (CyA) were compared in different in vitro models with respect to hepatocellular side effects. SDZ IMM 125 was less lipophilic than CyA and also decreased liposomal membrane anisotropy less. Furthermore, SDZ IMM 125 increased Na+ and Ca++ permeability across the liposomal membranes significantly more than CyA. The uptake of CyA and SDZ IMM 125 into freshly isolated rat hepatocytes was neither saturable, Na+ dependent or temperature sensitive, nor could it be inhibited vice versa, indicating passive diffusion. The diffusion coefficient of CyA was about two times higher than that of SDZ IMM 125, reflecting its higher lipophilicity. In primary hepatocyte monolayers the cellular concentrations of CyA were about two times higher than that of SDZ IMM 125. As an indicator of cholestasis the saturable uptake of cholyltaurine into isolated cells was found to be apparently competitively inhibited to the same extent by both compounds. In isolated perfused rat livers SDZ IMM 125 caused a significantly greater decrease in bile flow than did CyA. Release of lactate dehydrogenase from hepatocyte primary cultures and from isolated perfused livers were determined as parameter of cell damage. In both systems the cytotoxicity of SDZ IMM 125 was significantly higher than that of CyA. The data suggest that SDZ IMM 125 causes greater cholestatic and cytotoxic effects than CyA at equimolar cellular exposure.

Abstract
The in vitro micronucleus test is a well established test for early screening of new chemical entities in industrial toxicology. For assessing the clastogenic or aneugenic potential of a test compound, micronucleus induction in cells has been shown repeatedly to be a sensitive and specific parameter. As a measure for numerical and structural chromosome aberrations, the in vitro micronucleus test consists of determining the frequency of micronucleated cells in a representative fraction of cells in a culture. So far, manual counting has been the only method for evaluating microscopic V79 Chinese hamster cell preparations. To replace this tedious and time consuming procedure, a fully automatic system for micronucleus scoring in V79 cells by image analysis has been developed and introduced into the routine genotoxicity screening of drug candidates. The comparison of manual and automatic micronucleus analysis showed a high degree of concordance between the results obtained by the two techniques. For concentration series of cyclophosphamide (CP) and ethyl-methanesulphonate (EMS) as test compounds, the frequency of erroneously missed micronuclei through automatic scoring proved to be below 15% in comparison with manual scoring. Generally, false positive micronucleus decisions could be controlled easily by fast and simple relocation of the automatically detected patterns. The possibility to analyze 24 slides within 1 day by fully automatic overnight analysis and the high reproducibility of the results make automatic image processing a powerful tool for the in vitro micronucleus analysis.

Abstract
Exostoses of the external auditory canal can occur in patients living in coastal, southern California communities with a history of cold-water aquatic activities such as ocean surfing and swimming. Although most canal exostoses are asymptomatic, patients with canal obstruction greater than 80% can have recurrent episodes of external otitis and a related conductive hearing loss. In most cases, medical treatment resolves the symptomatic external otitis and related hearing loss. Patients recalcitrant to medical treatment are candidates for surgical removal of the exostoses. This report reviews the authors' surgical experience with 18 patients (27 ears) who have undergone surgical removal of exostoses. Their preferred surgical technique of transmeatal removal of exostoses with a specialized mallet and thin chisel under local anesthesia is described.

Abstract
Measurement of the frequency of micronuclei induced in cells by ionizing radiation or by chemical treatment is widely used to analyze cytogenetic damage. The microscopic scoring of micronuclei is a tedious and time-consuming procedure. Therefore, attempts have been made to automate micronuclei scoring by means of image analysis or flow cytometry. A new procedure for the flow cytometric analysis of chemically induced micronuclei in V79 Chinese hamster cells has been established in our laboratory. Debris was separated from micronuclei by means of a new gating procedure using area and width fluorescence of the stained suspension of micronuclei and nuclei. In order to test the sensitivity and specificity of this improved method of flow cytometric analysis, five well-known mutagenic compounds were tested. With the new technique, the frequency of micronuclei measured and analyzed corresponded well with results obtained by conventional microscopy. In addition, a large series of negative compounds, and weak, middle, and strong micronuclei inducers, were tested in order to establish criteria for discrimination between genotoxic and nongenotoxic compounds by flow cytometry. This new procedure for flow cytometric detection of micronuclei represents a quick, reliable, and relatively simple method for in vitro micronucleus testing.

Abstract
The mechanisms by which the immunosuppressive drug cyclosporine A (CsA) induces hypertension and nephrotoxicity are still not fully understood. Although smooth muscle cell (SMC) contraction is probably the mechanism of vasoconstriction, the direct contractive effect of CsA on SMCs has not yet been demonstrated. Thus, it was the purpose of this study to evaluate the direct effects of CsA in cultured SMCs through interactive image analysis. In aortic SMCs, CsA at the concentrations of 0.01, 0.1 and 1 microM, caused a concentration-dependent decrease of the planar cross-sectional area (PCSA) after 30 min and 60 min of treatment. The PCSA decreases were statistically significantly different from control at all concentrations. No cytotoxicity was observed under these conditions. Ten minutes preincubation of SMCs with a monoclonal antibody against endothelin-1 (ET-1) significantly prevented the CsA effects at 1 microM. When the same antibody was heat inactivated or an unspecific antibody (anti-desmin immunoglobulin G) was applied, the CsA-induced contractions were not affected. These data suggest that CsA can cause a direct contractive effect on vascular SMCs. This effect is partly mediated by ET-1.

Abstract
OBJECTIVE This study aimed to assess whether transient-evoked otoacoustic emissions (TEOAEs), which are known to be expressions of an intact cochlear function, could be useful for the rationale of hearing preservation in acoustic neuroma (AN) surgery. STUDY DESIGN The TEOAEs were measured before, during, and after surgery in a consecutive series of patients affected by cerebellopontine angle tumors. SETTING The study was performed at the Department of Otolaryngology, University "La Sapienza" of Rome. PATIENTS Five patients with AN and one with a meningioma totally involving the Cochlear (VIII) nerve. INTERVENTION Retrosigmoid approach on the ground of the limited AN size (within 20 mm) and the 30/70 rule, as proposed by the American Academy of Otolaryngology-Head and Neck Surgery nomogram. Two patients also were selected despite a poor hearing level and the absence of TEOAEs. MAIN OUTCOME MEASURES Preoperative and postoperative pure tone audiometry compared with TEOAEs. Intraoperative TEOAEs were compared with electrocochleographic findings. RESULTS The TEOAEs were found to be present also in patients with AN with poor pure-tone average (PTA) threshold (i.e., > 75 dB). Intraoperatively, TEOAEs recording showed to be markedly affected by the environmental noise as well as by specific intraoperative maneuvers, such as drilling of the internal auditory canal or tumor removal or both. In the three patients in whom hearing successfully was preserved. TEOAEs were present in the first postoperative days, despite a temporary deterioration of the PTA threshold. CONCLUSIONS The intraoperative use of TEOAEs showed to be scarcely reliable, whereas their presence in the preoperative assessment of patients with AN could lead to an extended number of patients to be selected for hearing-preservation surgery. Finally, an early postoperative identification of TEOAEs may be considered a favorable prognostic sign for foreseeing a delayed pure-tone hearing threshold recovery.

Abstract
The use of the immunosuppressant cyclosporine A (CsA) is limited by its adverse renal effects. Most recently, we reported that the drug markedly decreases the levels of the calcium-binding protein calbindin-D 28kDa in kidneys of male Wistar rats. In the present study, the potential relationship between drug-induced nephrotoxicity and the decrease in kidney calbindin-D 28kDa was investigated. Four groups of male Wistar rats were treated for 10 or 31 days with either the immunosuppressant CsA (50 mg/kg/day), FK-506 (5 mg/kg/day), rapamycin (5 mg/kg/day) or with the nonimmunosuppressive cyclosporine derivative 3'keto-[Bmt1]-[Val2]-CsA (SDZ PSC-833) (50 mg/kg/day), and the effects on calcium homeostasis, kidney histology and renal calbindin-D 28kDa were examined. Similar effects were found with CsA and FK-506; both drugs strongly reduced kidney calbindin-D 28kDa protein levels, increased urine calcium excretion, caused intratubular calcification, and induced basophilic tubules. In contrast, rapamycin and SDZ PSC-833 caused no decrease in renal calbindin-D 28kDa levels, no noticeable alterations in calcium metabolism, and no renal calcification. The results provide evidence for a link between decreased renal calbindin, increased calcium urine excretion, and intratubular kidney calcification. The present data show no correlation between the decrease in renal calbindin and the induction of basophilic tubules; however, it needs to be investigated if these apparently independent kidney effects may have a common origin upstream of calbindin expression.

Abstract
In man the immunosuppressive drug Cyclosporine A (CsA) has been used successfully in organ transplantation and in the treatment of autoimmune disorders. The drug, however, causes side effects which occur mainly in the kidney but also in the liver. The mechanisms leading to the hepatic side effects are not yet fully understood. Because reactive oxygen production is a common mechanism of drug toxicity, the goal of this study was to evaluate whether CsA induces oxidative stress in rat liver cells. In primary rat hepatocyte 20-h cultures, CsA caused a concentration-dependent increase of free reactive oxygen species, thiobarbituric acid reactive substances, loss of protein thiols and decrease of molar ratios of glutathione and glutathione disulfide in the range of 0 to 50 microM CsA. The weakening or enforcement of the cellular glutathione state by the glutathione synthesis inhibitor buthionine sulfoximine or the glutathione disulfide -reducing agent dithiothreitol either increased or inhibited the CsA cytotoxicity, as determined by lactate dehydrogenase release. CsA also decreased the level of endogenous antioxidant ascorbic acid and increased its oxidation product dehydroascorbic acid. Supplementation of the cell cultures with ascorbic acid significantly reduced the CsA toxicity. The antioxidant DL-alpha-tocopherol-polyethylene-glycol-1000-succinate partly decreased CsA-mediated reactive oxygen species formation, totally decreased thiobarbituric acid reactive substances formation, prevented the loss of protein-bound sulfhydryl groups and in addition totally inhibited the CsA cytotoxicity. The present data provide good evidence that oxidative stress is part of the mechanism by which CsA causes toxicity in rat liver cells.

Abstract
On the grounds of positive results obtained with Meniere's patients, agents such as glycerol and mannitol have been included in the therapeutical protocol of other cochlear disorders presenting with hearing loss either of sudden onset, but not observed at an early stage, or accompanied by tinnitus and aural pressure. Intravenous infusions of either 10% glycerol or 18% mannitol were given to selected patients 3 to 6 times with a time interval of 1 to 3 days. Hearing loss, tinnitus and aural pressure were evaluated as improved, unchanged or worsened. In 33% of the glycerol group and 23.8% of the mannitol group we observed hearing threshold improvement, while aural fullness improved in 45% of the glycerol and 56.2% of the mannitol groups, and tinnitus was only relieved in 13.1% of the glycerol and 5.8% of the mannitol group. A parallel experimental study was carried out on guinea-pigs in order to shed light on the effects of mannitol and glycerol on the inner ear. Cochlear blood flow was measured with a laser Doppler flowmeter at the level of the basal turn of the cochlear lateral wall, both in normal and hydropic guinea-pigs, before and after osmotic intraperitoneal infusion. Basal values in the normal cochlea were much higher than in the hydropic one, and both mannitol and glycerol markedly influenced the local blood flow in the normal cochlea, giving few or no changes in the hydropic one.

Abstract
The indole-3-carboxylic acid scopoine ester. SDZ ICT 322, is a selective hydroxytryptamine (5-HT3) antagonist, which after chronic treatment causes posterior subcapsular cataracts and skin changes such as hair loss, hyperaemia, desquamation and hyperkeratosis in rats. The detailed mechanisms underlying these changes are not yet known. In order to evaluate a possible oxidative stress-induced pathomechanism of SDZ ICT 322, the antioxidative defence capacity in rats was modulated by feeding a special vitamin E- and selenium-deficient (VE/SeD) diet. For this purpose 32 male Wistar rats, age 4 weeks, were pretreated for 8 weeks with either a VE/SeD diet or a normal standard diet. Each dietary group was divided into 8 control and 8 SDZ ICT 322-treated animals. SDZ ICT 322 was administered in feed to rats at an adjusted daily dose level of 125 mg/kg for 14 weeks. Plasma levels of SDZ ICT 322 as well as of the N-desmethyl metabolite were similar in rats fed the different diets in weeks 3, 6 and 14. In SDZ ICT 322 treated VE/SeD rats cataracts were observed by week 7, whereas in rats fed normal diet cataracts were first seen in week 14. In the normal dietary group no corneal opacity was found after SDZ ICT 322-treatment; however, a corneal opacity was seen in the deficiency group in parallel with one of the cataract animals in week 7. The incidence and severity of clinical skin signs were greater and their onset was earlier in the deficiency dietary group: onset occurred after 6 weeks compared to 9 weeks on the normal diet. Thiobarbituric acid reactive substances, an indicator mainly of oxidized lipids, were statistically significantly increased in the urine of rats administered SDZ ICT 322 and the VE/SeD diet. Uric acid, which is an endogenous antioxidant was statistically significantly decreased in the urine and plasma of SDZ ICT 322 VE/SeD treated rats. The clinical eye and skin changes occurring early after VE/SeD feeding, the unchanged drug plasma exposure and unchanged drug metabolite formation in combination with the general pro-oxidative activity of the drug suggest an oxidative stress-mediated pathomechanism of SDZ ICT 322 at high dose levels in rats.

Abstract
Electrocochleography was conducted in 185 patients with Menière's disease and 117 with sudden deafness. Electrophysiological findings from the two groups were compared in order to identify pathogenic similarities between the two conditions. Parameters investigated were the summating potential (SP)/action potential (AP) ratio, audiometric profiles and audiometric changes after medical therapy. A high SP/AP ratio was found in the patients with sudden deafness, thus supporting a possible hydropic aetiology in this group. In conclusion, electrocochleography can be considered a useful technique as it permits identification of an hydropic condition in certain cases of sudden deafness.

Abstract
BACKGROUND Cardiac troponin I (CTn I) has been shown to be a marker of myocardial injury. Incomplete distribution of cardioplegic solution may be responsible for injury in jeopardized myocardial areas. The aim of this study was to compare CTn I release with respect to the route of delivery of crystalloid cardioplegia, either antegrade only or initially antegrade followed by retrograde cardioplegia for the remainder of the operation, in patients undergoing elective coronary artery bypass grafting. METHODS Sixty patients were randomly assigned to one of two cardioplegia groups. Cardiac troponin I concentrations were measured in serial venous blood samples drawn just before cardiopulmonary bypass and after aortic unclamping at 6, 9, 12, and 24 hours and daily thereafter for 5 days. Analysis of variance with repeated measures was performed to test the effect of route of delivery, coronary disease, collateral circulation, risk of cardioplegia maldistribution, and number of grafts on release of CTn I. RESULTS Compared with the antegrade route, the combined route offered no advantage in an unselected group of patients undergoing an elective first cardiac operation and having preserved left ventricular function. The CTn I concentration did not differ between groups for any of the samples considered. In patients with major left main coronary artery stenosis, CTn I release was significantly higher at hour 9 in the antegrade group than in the group with combined delivery. CONCLUSIONS A combined route of delivery of crystalloid cardioplegia is beneficial in patients with major stenosis of the left main coronary artery. Cardiac troponin I sensitivity is relevant in this study. Release of CTn I should be useful in determining the best form of myocardial protection for each patient.

Abstract
RNase P is a ribonucleoprotein enzyme in all organisms and organelles investigated so far, with the exception of chloroplasts where no enzyme-associated RNA has been detected to date. As an approach to answer the question whether an RNA component is present in RNase P from photosynthetic organelles, we have used a phylogenetically oriented strategy and searched for RNase P RNA in a postulated intermediate in plastid evolution, the cyanelle of Cyanophora paradoxa. We have detected a 351 nucleotide long RNA similar to cyanobacterial RNase P RNAs, with a proposed secondary structure that closely resembles a bacterial consensus. The RNA is encoded on the cyanelle genome and copurifies with enzyme activity. The RNA is not catalytically active by itself, but the activity of the cyanelle RNase P holoenzyme is destroyed by nuclease treatment, indicating an essential role of the RNA. Hence cyanelle RNase P, combining properties of bacterial and eukaryotic enzymes, occupies an intermediate position in RNA enzyme evolution. The first description of an RNA component in RNase P from a photosynthetic organelle might thus be an important step towards an understanding of plastid RNase P structure and function.

Abstract
Despite the widespread use of cyclosporine A (CsA), its mechanism of action and side effects are not yet completely understood. There exists a large body of evidence suggesting that disturbance of calcium homeostasis is a critical step in the cascade of cellular and molecular events induced by the drug. As recently shown in our laboratory by two-dimensional protein gel electrophoresis (2-DE) analysis of kidney homogenates, CsA induced numerous changes in several kidney proteins. One kidney protein in particular was shown to be strongly down-regulated by the drug. In this work we report the identification of the strongly decreased kidney protein as calbindin-D 28kDa, a vitamin D-dependent calcium-binding protein associated with calcium handling by cells. The assignment of the down-regulated protein spot is based on its internal amino acid sequence analysis and its specific reaction with a monoclonal antibody raised against calbindin-D 28kDa. In kidney homogenates of male Wistar rats treated with 50 mg/kg/d CsA for up to 28 days, calbindin levels were measured by ELISA and were shown to be continuously decreased with prolonged CsA treatment. To our knowledge, this is the first report describing the effect of CsA on kidney calbindin-D 28kDa protein levels. Further studies are needed to elucidate whether the CsA-mediated down-regulation of the calcium-binding protein calbindin-D 28kDa may be a critical factor for the renal adverse effects induced by this drug.

Abstract
The effects of etomoxir, an irreversible carnitine palmitoyltransferase I inhibitor, on the liver protein pattern and on liver morphology were examined by two-dimensional gel electrophoresis in female Sprague-Dawley rats treated with 125 mg/kg/day etomoxir for 28 days. In livers of treated animals a protein spot was found which was not present in controls. The spot was identified by internal amino acid sequence analysis as the adipose differentiation-related protein (ADRP). The expression of ADRP in liver is a novel finding as the protein has been described previously as adipocyte-specific. Additionally we found histopathologic evidence of lipid accumulation in the livers of etomoxir rats. The data show that for each treated rat there was a good correlation between ADRP levels and degree of lipid droplet formation. This observation may suggest a potential relationship between drug-induced expression of ADRP in liver and lipid accumulation.

Abstract
Lingual thyroid is an uncommon cause of oropharyngeal mass, due to a congenital anomaly of thyroidal development and migration: It is defined precisely as the presence of thyroid tissue in the midline of the tongue base between circumvallatae papillae and the epiglottis. We report a case of lingual thyroid in which the integration of clinical data, sonography, color-duplex Doppler, MRI and scintigraphy was determinant in demonstrating the disease. A 22-year-old woman presented with a sensation of foreign body in the throat, dysphonia, dyspnoea and dysphagia; we performed sonography (7.5 MHz linear probe), color Doppler (7 MHz Doppler frequency, PRF 3500 Hz) and MRI (1.5 T, spin-echo T1- and T2-weighted images with administration of Gd-DTPA); a scan with 123I demonstrated a relevant uptake at the base of the tongue, but no uptake at the typical thyroid location. The gland was removed and partially transplanted in the strap muscles of the neck.

Abstract
The effects of cyclosporine A (CsA), a potent immunosuppressive drug, were examined in rat liver and kidney samples using two-dimensional electrophoretic protein analysis. Of a total of 370 liver and 336 kidney spots analyzed, 8% (29 spots) and 6% (19 spots), respectively, showed a significant drug-induced change (p < 0.01), which was predominantly reflected in increased protein abundance (62% and 74% of the changes, respectively). Of the 48 proteins changed in either organ, 14 were most probably common to both tissues and one of these was significantly increased in both the liver and the kidney. Most of the other 13 showed similar trends (either increases or decreases) in both organs. However, the most striking drug effect seen in this study concerned an unidentified protein present only in the kidney, which completely disappeared upon CsA treatment. It was also investigated whether the drug-induced changes could be prevented by the coadministration of the radical scavengers vitamin E and C with CsA. Spots changed by the administration of the drug were classified according to three different categories, based on their response profiles in rats treated with CsA in combination with the vitamins: (i) spots which were changed by CsA as well as by CsA in combination with the vitamins (12 liver and 4 kidney spots), (ii) spots which were changed by CsA and showed an additional increase of this change by CsA plus the vitamins (no liver and 4 kidney spots), and (iii) spots which were changed by CsA but not by CsA in combination with the vitamins (8 liver and 6 kidney spots). These results showed that in both organs the vitamins were able to prevent around 30% of the effects caused by CsA, and that two-dimensional gel electrophoresis is an excellent tool to demonstrate such drug interactions at the molecular level.

Abstract
The current trend in myocardial revascularization is to use arterial grafts in most, if not all cases. The right internal thoracic artery was a logical choice once the left internal thoracic artery patency on the LAD was known. This study presents our experience of using both attached internal thoracic arteries (ITA). Between January and October 1990, 159 myocardial revascularizations were performed in our department. In 117 cases, bilateral ITA grafting was used with non exclusion criteria. There were 100 male and 17 female patients, with a mean age of 61 +/- 8. The LITA was anastomosed to the LAD in 44 cases, and to the marginal artery in 74. The RITA was anastomosed to the LAD in 68 cases, to the marginal artery in 47 and to the right coronary artery in 2. An average of 3.5 bypasses per patient, including saphenous vein grafts, were performed. Six patients (5%) died within 30 days. Four patients (3.4%) were diagnosed as having periperative myocardial infarcts. There were no reoperations for bleeding. One patient (0.9%) presented a sternal wound infection. Mean follow-up was 18 +/- 7 months. Six patients died during the follow-up and the survival rate was 91%. Ninety-five patients (91%) were symptom-free, 9 patients had a recurrent angina. Postoperative coronary angiography was performed in 11 patients (10%).(ABSTRACT TRUNCATED AT 250 WORDS)
