Abstract
Purpose: To evaluate MR findings in early (T1 and T2 stages) glottic carcinomas and the predictive value of MR imaging for the rate of 5-year local control with radiation therapy. Material and Methods: Eighty-three patients with early glottic carcinomas were prospectively examined with MR at 1.5 T. MR investigation included unenhanced T1-weighted, T2-weighted, dynamic and contrast-enhanced T1-weighted images. Three patients with presumed advanced diseases on MR were initially treated with total laryngectomy and were excluded from the study. The remaining 80 patients were treated with radiation therapy with curative intent. Tumor detectability, size and relationship to the thyroid cartilage were determined on MR images. The MR findings were then correlated with the rate of local control. Results: Forty-eight of 80 lesions (60%) were detected on MR imaging. All detected lesions but 1 demonstrated increased signal on T2-weighted images. The lesions were best delineated on dynamic images (statistically significant). The 5-year local control rate with radiation therapy was 72%. Univariate analysis revealed clinical T stage, MR detectability, tumor size and relationship to the thyroid cartilage as significant predictors. Multivariate analysis revealed that the relationship to the thyroid cartilage was an independent factor. Conclusion: MR provides prognostic information about the results of definitive radiation therapy. To evaluate the tumor extension in lesions detected on precontrast MR images, contrast-enhanced dynamic images should be obtained.

Abstract
There is no one common immunotherapy for the treatment of head and neck cancer (H&N cancer). A streptococcal agent, OK-432, which is classified as a biological response modifier (BRM), is occasionally used by means of local administration for recurrent H&N cancer, and the response rate is approximately 18%. In regard to specific immunotherapy, a murine monoclonal antibody (named mAb 225) against the epidermal growth factor receptor (FGFR) that is frequently overexpressed in H&N cancer has been produced in the U.S.A. Furthermore, to obviate human anti-mouse antibody responses, a chimeric human-to-murine version of mAb 225 (C225) was developed by exchanging the constant regions of mAb 225 to counterparts in human immune globulin. Phase I clinical trials of C225 in the U.S.A. demonstrated that treatment with C225 was well tolerated and that C225 given in combination with cisplatin has biologic activity. On the other hand, many tumor antigens recognized by cytotoxic T lymphocytes (CTL) have been identified from a variety of malignant tumors and some of them, including the MAGE-3 antigen, are frequently expressed in H&N cancer. We identified an MAGE-3-derived epitope recognized by HLA-A24-restricted CTL from peripheral blood mononuclear cells (PBMC). In contrast we failed to generate CTL specific for MAGE-3+/HLA-A24+ tumors from PBMC in any of 5 HLA-A24+ cancer patients whose tumors expressed the MAGE-3 gene. Therefore, we did not apply MAGE-3-derived CTL epitope in clinical uses such as peptide vaccine and peptide pulsed dendritic cell infusion for H&N cancer.

Abstract
BACKGROUND AND PURPOSE Tumor volume and cartilage invasion have been suggested as prognostic factors of glottic carcinomas following definitive radiation therapy. Radiologic examinations provide additional information regarding the deep extension of tumor. We determined whether dynamic helical CT can predict local control of early (T1 and T2 stage) glottic carcinomas treated with definitive radiation therapy. METHODS Sixty-eight patients with early glottic carcinoma evaluated on pretreatment dynamic helical CT were treated with definitive radiation therapy. Tumor detectability, maximum dimension, tumor volume, and involvement of anatomic subsites (anterior commissure, ventricle, subglottic region, and thyroid and arytenoid cartilages) were determined by consensus by three radiologists without previous knowledge of the clinical information. The CT findings were correlated with local control. RESULTS The two-year local control rate was 76%; 91% for T1 and 60% for T2 lesions. Univariate analysis revealed clinical T stage, tumor detectability, maximum dimension, tumor volume, anterior commissure involvement, ventricle involvement, and thyroid cartilage involvement as significant prognostic factors. Thyroid cartilage involvement was an independent predictor by multivariate analysis. The lesions separate from the thyroid cartilage had a 95% probability of local control, whereas the lesions adjacent to the cartilage had only a 42% control rate. CONCLUSION Dynamic helical CT provides prognostic information for the results of definitive radiation therapy. Patients with a tumor adjacent to the thyroid cartilage had an increased risk of local failure.

Abstract
We examined the frequency of p53 mutations in 38 oropharyngeal squamous cell carcinomas (SCC), using both a yeast functional assay and a conventional immunohistochemical staining method (IHC) to detect p53 mutations. We also explored the clinical importance of p53 mutations in oropharyngeal SCC. An accumulation of p53 protein was detected in 17 of the 38 (45%) tumors by IHC, whereas the yeast-based assay detected 6 additional p53 mutations, for a total of 23 tumors (61%) with p53 mutations. The cDNA sequencing analysis revealed that the 6 mutations undetected by IHC consisted of 3 frameshift, 1 nonsense and 2 missense mutations. Thus, the yeast functional assay was more sensitive than conventional IHC for detecting p53 mutations. Subsequently, the relationship between p53 mutations and the clinico-pathological parameters in oropharyngeal SCC was evaluated using the results of the functional assay. Mutation of p53 was not associated with the patient age, sex, tumor stage or degree of tumor cell differentiation. Interestingly, heavy drinking had a significant positive correlation with the p53 mutation, but heavy smoking did not, suggesting that prolonged exposure to alcohol is more related to p53 mutation in oropharyngeal SCC than to tobacco consumption. Radiation sensitivity was examined by comparing tumor size on magnetic resonance images before and after completion of therapy with 45 Gy radiation, in the 18 cases of T2 oropharyngeal SCC that were initially treated by radiotherapy. The results showed that tumors with wild-type p53 decreased in size significantly compared to those with mutant p53. In 33 patients treated with curative intent, the overall survival after the completion of therapy was better in patients with a wild-type p53 tumor than in patients with a mutant p53 tumor. We conclude that p53 mutation is associated with radiation resistance and a decreased probability of survival in oropharyngeal SCC.

Abstract
BACKGROUND The human MAGE-3 gene encodes tumor-specific antigens that are recognized by cytotoxic T lymphocytes (CTLs) and expressed in a high percentage of various malignant tumors. Of the five MAGE-3-derived CTL epitopes identified to date, two nonapeptides (TFPDLESEF and IMPKAGLLI, designated MAGE-3.A24a and MAGE-3.A24b, respectively) can be expressed on the tumor surface by binding to the HLA-A24 molecule, which is the most frequent HLA class I molecule in Asian populations. To compare the immunogenecities of the two peptides, individual specific CTL lines were generated for each peptide (MAGE-3.A24a and MAGE-3.A24b). METHODS Peripheral blood mononuclear cells (PBMCs) from four HLA-A24+ healthy donors were stimulated in vitro with autologous dendritic cells pulsed with MAGE-3.A24a, MAGE-3.A24b or both and were subsequently cultivated with a cytokine combination including interleukin-2. RESULTS We succeeded in generating peptide-specific CTL lines in two of the four donors. The two CTL lines showed similar cytolytic levels against three MAGE-3+/HLA-A24+ cancer cell lines and also target cells pulsed with the corresponding peptide. Cytolytic activities were blocked by either anti-CD8 or anti-HLA-A24 monoclonal antibodies. CONCLUSIONS The results suggest that MAGE-3.A24a and MAGE-3.A24b peptides have equal potential in inducing MAGE-3-specific and HLA-A24-restricted CTLs.

Abstract
Evidence has accumulated indicating that HLA-A2-restricted CTLs specific for human wild-type sequence p53 epitopes lyse tumor cells expressing mutant p53. To explore the possibility that wild-type sequence p53 peptides could also be used in vaccines for patients expressing HLA-A24 antigen, another frequent HLA class I allele, we investigated the induction of HLA-A24-restricted p53-specific CTLs from the peripheral blood lymphocytes of normal donors. Of six p53-derived peptides possessing an HLA-A24 binding motif, the p53 peptide 125-134 (p53(125-134)) was found to have a high binding capacity and induced peptide-specific CTLs from peripheral blood mononuclear cells, using peptide-pulsed autologous dendritic cells and subsequent cultivation with cytokines interleukin 2 and interleukin 7. Bulk CTL populations lysed peptide-pulsed HLA-A24+ targets as well as HLA-A24+ squamous cell carcinoma of the head and neck (SCCHN) cell lines. However, IFN-gamma pretreatment of HLA-A24+ SCCHN cell lines was necessary for lysis, suggesting that a ligand density higher than that normally expressed by tumor cells is required for these CTLs to mediate lysis. Moreover, a cloned CTL, designated TH#99, isolated from the bulk population by limiting dilution, lysed HLA-A24+ SCCHN targets more efficiently than the bulk CTL population. Lysis was inhibited by anti-HLA class I monoclonal antibody but not by anti-HLA-DR monoclonal antibody. These results indicate that HLA-A24-restricted CTLs recognizing the wild-type sequence p53(125-134) can be generated using autologous dendritic cells from precursors present in peripheral blood lymphocytes obtained from normal HLA-A24+ donors. This finding suggests that vaccine strategies targeting wild-type sequence p53 epitopes can be extended to a wider range of cancer patients.

Abstract
BACKGROUND Association between certain human leukocyte antigen (HLA) types such as HLA-A1 and -A3 and squamous cell carcinoma of the head and neck (SCCHN) has been demonstrated in the Caucasian population. HLA typings in these studies were performed by conventional serological methods. However, recent comparison studies between serological and molecular typings have revealed that the former are often inaccurate. METHODS The frequency of HLA-A alleles in 100 Japanese patients with SCCHN and 100 control subjects was determined by the polymerase chain reaction, with primers specific for the HLA-A locus, in combination with dot-blot hybridization with 31 sequence-specific oligonucleotides. RESULTS The frequencies of HLA-A*2602 and HLA-A*3303 were higher and those of HLA-A*2603 and HLA-A*3101 were lower in the patients with SCCHN than in healthy controls, but these differences were not statistically significant. In the 39 male patients with laryngeal carcinoma, the most common malignancies in Japanese patients with SCCHN, the frequency of HLA-A*2402 was significantly lower than that in the 80 male controls; however, after correction of the P value, statistical significance was not confirmed. In oral carcinoma patients, the frequency of HLA-A*2402 was significantly higher than that in healthy controls. CONCLUSIONS These results suggest that the contribution of certain HLA-A alleles to susceptibility to SCCHN may differ between sites in the head and neck regions, despite these cancers being of an identical histological type, and that HLA-A*2402 may influence the development of oral carcinoma in Japanese patients.

Abstract
The application of platelet-activating factor (PAF) to the nasal mucosa of humans has been shown to increase histamine-induced hyper-reactivity. To test the hypothesis that PAF acts by increasing the reactivity of sensory nerve endings in the nasal mucosa to histamine, we examined PAF-stimulated rat trigeminal nerve ganglion cells. We found that relatively low concentrations of PAF (10(-12)-10(-9) M) induced increased histamine H1 receptor mRNA expression. This increase appeared as early as 1 h after PAF stimulation, peaked at 4 h, and disappeared after 24 h. The PAF receptor antagonist WEB2086 inhibited the increased expression of histamine H1 receptor mRNA induced by PAF, suggesting that the effects of PAF are mediated by specific receptors. This PAF effect was abolished by actinomycin D, suggesting that PAF induces de novo transcription of histamine H1 and/or PAF receptor mRNA. PAF may be important in the hyper-responsiveness of nasal mucosa exposed to histamine.

Abstract
Five MAGE-3-derived peptides carrying an HLA-A24-binding motif were synthesized. Binding capacity of these peptides was analyzed by an HLA-class-I stabilization assay. Two of the 5 peptides bound to HLA-A*2402 molecule with high affinity, and 3 peptides with low affinity. Peripheral-blood mononuclear cells (PBMC) depleted of CD4+T cells were stimulated with the peptides to determine whether these peptides would induce cytotoxic T lymphocytes (CTL) from PBMCs obtained from 7 healthy HLA-A*2402+ donors. Peptide M3-p97 (TFPDLESEF; corresponding to amino-acid residues 97-105 of MAGE-3), with high binding capacity to the HLA-A*2402 molecule, elicited the peptide-specific and HLA-A24-restricted CD8+CTL lines in 2 of the 7 donors, while none of the 4 other peptides induced CTL specific for the corresponding peptide in any of the donors. CTL lines induced by stimulation with peptide M3-p97 exhibited cytolytic activities against HLA-A*2402 transfectant cell lines (C1R-A*2402) in the presence of peptide M3-p97, but not in unloaded or irrelevant peptide-pulsed C1R-A*2402 cells. The CTL lines and a cloned CD8+CTL isolated from one of the bulk populations by limiting dilution could lyse MAGE-3+/HLA-A*2402+ squamous-cell-carcinoma(SCC) lines but neither MAGE-3-/HLA-A*2402+ nor MAGE-3+/HLA-A*2402- SCC lines, indicating that M3-p97 can be naturally processed and presented on the tumor-cell surface in association with HLA-A*2402 molecules. Combined with the 4 currently reported CTL epitopes derived from MAGE-3 and presented by HLA-A1, HLA-A2, HLA-A24 or HLA-B44, identification of this CTL epitope presented by the HLA-A*2402 molecule will extend the application of MAGE-3-derived peptides for immunotherapy for cancer patients.

Abstract
We performed neurologic and otologic examinations in 14 patients with Fisher's syndrome to determine whether its manifestations inducing acute ophthaloplegia, ataxia and areflexia may involve the auditory and vestibular systems. Tests included pure tone audiometry, auditory brainstem response, observations of nystagmus, smooth pursuit test, saccade test, optokinetic nystagmus test, and the caloric test. One patient showed downbeat nystagmus and lateral gaze nystagmus without restriction of eye movement, two patients showed dysmetria on saccades without restriction of eye movement, and three patients showed superimposed saccadic eye movement on smooth pursuit without lateral gaze nystagmus. The abnormalities in those six cases could not be explained by solely muscular weakness, but also appeared to involve the central oculomotor system. In the other patients, nystagmus could be explained by muscular weakness alone. Additionally, three patients, including two patients with dysmetria on saccades, showed a unilateral diminished response to caloric testing with no severe restriction of eye movements. In evaluating the auditory brainstem response of these three patients, one patient, who showed abnormality on the saccade and caloric tests, showed an elongation of wave I latencies and of wave I-III interpeak latencies at both ears, and one other patient showed an elongation of wave III-V interpeak latencies at both ears. This disorder may involve the peripheral and central auditory systems as well as the peripheral vestibular system.

Abstract
BACKGROUND The mediators involved in eosinophil accumulation in diseases such as allergy continue to be an area of interest, even though little is known regarding the signaling involved in the human cell type recruitment. In the present study, we demonstrate a novel modulatory role of tyrosine kinase and tyrosine phosphatase activities on normal human eosinophil chemotaxis induced by different groups of chemoattractant. METHODS Purified eosinophils were obtained from normal healthy volunteers with the CD16-negative procedure. Chemotactic activities against platelet-activating factor (PAF), vasoactive intestinal peptide (VIP) and eotaxin were assessed using a 48-well microchemotaxis chamber assay. Purified eosinophils were pretreated with herbimycin A, erbastatin or pervanadate to examine the role of tyrosine kinase in chemoattractant signaling. RESULTS Pretreatment of eosinophils with the tyrosine kinase inhibitors herbimycin A and erbstatin significantly blocked chemotaxis induced by eotaxin whilst both inhibitors augmented chemotaxis induced by VIP; however, they had no effect on PAF-induced chemotaxis. On the other hand, pretreatment of eosinophils with the phosphotyrosine phosphatase inhibitor pervanadate resulted in augmentation of eotaxin-induced chemotaxis and inhibition of VIP-induced chemotaxis, but it had no effect on PAF-induced chemotaxis. CONCLUSIONS These results suggest that protein kinase plays a modulatory role in eosinophil chemotaxis induced by various chemoattractants.

Abstract
BACKGROUND Eosinophil granule proteins deposition at the site of allergic inflammation contributes to the late-phase reaction of hypersensitivity diseases. In the present communication, we describe the effect of human eotaxin on normal human eosinophil exocytosis measured as degranulation of eosinophil-derived neurotoxin (EDN). METHODS Purified eosinophils were obtained from normal healthy volunteers with the CD16-negative procedure. Purified eosinophils were stimulated with various concentrations of eotaxin and the amount of EDN released was analysed by radioimmunoassay. Flow cytometry was used to examine the surface expression of adhesion molecules on eosinophils. RESULTS Eotaxin significantly induced EDN release in a dose-dependent manner. The potency of eotaxin in this effect was equal to that of RANTES, and comparable to that of platelet-activating factor. Eotaxin-induced EDN release was blocked by cytochalasin B in a dose-dependent manner. The surface expression of CD11a, CD11b, CD18 and VLA-4 adhesion molecules on normal human eosinophils were not modulated by eotaxin stimulation. CONCLUSIONS These results indicate that eotaxin may play an important role not only as a selective chemotaxin for the cell type but also as a secretagogue. Furthermore, they demonstrate a degranulation mechanism(s) involving cytoskeletal changes which is probably independent of the quantitative expression of adhesion molecules.

Abstract
We have demonstrated degranulation of mast cells in the endolymphatic sac as well as an increase in audiological threshold shift in the experimental animal models following antigen provocation. Mast cells, however, release such chemical mediators as histamine, platelet activating factor (PAF), and leukotriene due to an antigen-antibody reaction on the cell surface. The aim of this study was to clarify the major chemical mediators responsible for hearing impairment in the animal models following antigen provocation. Guinea pigs were actively sensitized with DNP-Ascaris and provoked with an injection of DNP-BSA. A significant audiological threshold shift was observed at 1, 10, 24, and 72 h following challenge with allergen. The peak shift was at 10 h; all changes were reversed after 7 days. This threshold shift was abolished by prior injection of either a histamine- or PAF-receptor antagonist to allergen, but not of a leukotriene-receptor antagonist. Results suggest that histamine and PAF are involved in the hearing impairment induced by allergen exposure in the guinea pig.

Abstract
Although Type I allergy is a trigger for provoking chronic inflammation, whether allergic sinusitis (AS) can be distinguished from sinusitis due to chronic infection is still debated. This study was performed to characterize inflammatory cells in AS and to determine whether patients with AS differ from patients with chronic suppurative sinusitis (CSS). 5 patients with AS and 10 patients with CSS were investigated. Cellular infiltration was studied using immunohistochemistry with monoclonal antibodies using CD3, CD4, CD8, CD25, major basic protein (BMK13), eosinophil cationic protein (EG2), neutrophil elastase, and tryptase. There were no differences in CD3+, CD4+, CD25+, and tryptase+ cells between the groups. Whereas the total number of eosinophils (BMK13+) also did not significantly differ, the number of activated eosinophils (EG2+) was significantly higher (P < 0.05) in patients with AS. Furthermore, a statistically significant increase in the percentage of activated eosinophils to total eosinophils (P < 0.05) was observed in patients with AS. In contrast, the number of neutrophil elastase+ cells was significantly higher (P < 0.05) in patients with CSS. These results suggest that patients with AS can be distinguished immunohistochemically from patients with CSS, with AS being distinguished by activated eosinophil infiltration.

Abstract
BACKGROUND Angioimmunoblastic lymphadenopathy (AILD) is rare in the head and neck and its definition remains controversial. METHOD A case of AILD with an ulcer of the lateral pharyngeal wall was studied for viral infection, immunohistologic findings and T-cell receptor (TCR) V beta rearrangement. RESULTS We observed elevation of antibodies against herpes simplex virus and herpes zoster virus as well as Epstein-Barr virus considered closely associated with AILD. The affected neck lymph node showed a preponderance of T-cells, predominantly CD4+ over CD8+ T-cells and all V beta gene families were expressed in the T-cells without enhancement of any particular TCR gene usage. CONCLUSION Viral infection may occur easily in patients with AILD, possibly owing to immunodeficiency. Assessment of TCR V beta gene usage indicated T-cells to non-specifically become lymphomatous in AILD-like T-cell lymphoma.

Abstract
The MAGE-4 gene, a member of the MAGE gene family, is expressed in various cancers, including head-and-neck squamous-cell carcinomas (HN-SCC), but is not expressed in any normal tissues except for the testis and placenta. The aim of this study was to determine whether serum MAGE-4 protein is a useful tumor marker for detection of HN-SCC. An enzyme-linked immunosorbent assay was used to measure serum level of MAGE-4 protein. The serum level of MAGE-4 in pre-operative HN-SCC patients was significantly higher than that in patients with non-malignant diseases (NMD) of the head and neck, volunteers undergoing cancer screening (VOL), or healthy donors (HD). When the cut-off level was determined at 1.15 ng/ml (mean plus 3 SD of HD), sera from 28 of 96 patients with HN-SCC (p < 0.0001 vs. the other groups), 7 of 82 patients with NMD, 2 of 92 with VOL, and 0 of 68 HD were positive for MAGE-4. Serum levels of MAGE-4 protein in all 7 HN-SCC patients whose sera were positive for MAGE-4 before operation decreased after operation, and, in one patient, a renewed rise in serum level was followed by recurrence. These results indicate that MAGE-4 protein is detectable in sera of a significant number of HN-SCC patients, and that serum MAGE-4 protein might be a useful tumor marker to monitor the recurrence of MAGE-4-positive HN-SCC.

Abstract
Emedastine difumarate (emedastine), an anti-allergic agent with anti-histaminic properties, was studied for its effect on human eosinophil chemotaxis induced by platelet activating factor (PAF). Peripheral blood eosinophils (98% purity) were obtained from healthy donors and chemotaxis assay were performed in microchemotaxis chambers. Emedastine showed a significant inhibitory effect on 10(-6) M PAF-induced eosinophil chemotaxis, in dose dependent fashion, at concentrations from 10(-6) to 10(-8) M. Conversely, no inhibitory effect was observed on human neutrophil chemotaxis. Pretreatment of eosinophils with Pyrilamine did not affect PAF-induced eosinophil chemotaxis. Thus emedastine appears to possess a potent and selective inhibitory effect on eosinophils chemotaxis, an action which is probably unrelated to its anti-histamine properties.

Abstract
Eosinophilic granuloma of the soft tissue (EOSG) is a rare disease of unknown cause. Since the in vivo mechanism of eosinophilia remains unclear, the present study was performed to investigate the mechanism of the infiltration of eosinophils into the granuloma tissue. Immunohistochemical techniques and an eosinophil chemotactic assay were used in analysis. Peripheral blood eosinophils obtained from one patient showed an increased chemotactic response against tissue extract that was inhibited by pretreatment with anti-IL-5 antibodies. Eosinophils obtained from the peripheral blood of patients with EOSG showed a significant increase in chemotactic activity toward 10(-9) M recombinant human (rh) IL-5 versus that of healthy individuals, whereas eosinophils from granuloma tissue showed no chemotactic response toward rhIL-5, indicating that IL-5 may deactivate the eosinophils. Immunohistochemical studies showed that CD4+ cells were predominantly found in the extrafollicular region, along with interleukin-5+ (IL-5) cells. Staining of the adjacent 3-micrometers sections for CD3, eosinophils, and IL-5 revealed that most of the IL-5 immunoreactive CD3+ cells exhibited cytoplasmic staining. Conversely, 97% of IL-5+ eosinophils were stained peripherally in a ring-like manner, suggesting that IL-5 was bound to its cell surface receptor on the eosinophil. IL-5 mRNA expression was detectable in the CD3+T lymphocytes but not in eosinophils from granuloma tissue. These findings suggest that locally produced IL-5 from T lymphocytes may enhance the infiltration of eosinophils into the eosinophilic granuloma.

Abstract
Although many studies have suggested a relation between allergy and Ménière's disease, the pathophysiology of this condition remains controversial. The aim of this study was to clarify whether an anaphylactic reaction in the inner ear can disturb hearing and equilibrium, and whether such disturbances recur in response to repeated anaphylactic reactions. Increases in audiological threshold, nystagmus, and endolymphatic hydrops were observed in response to a single exposure to antigen administered to actively sensitized guinea pigs. The increase in audiological threshold was maximal 10 h after antigen challenge (p < 0.005) and returned to the baseline level after 7 days. Nystagmus and the increase in audiological threshold induced by antigen exposure were inhibited by prior administration of pemirolast potassium (p < 0.05), an inhibitor of chemical mediator release from mast cells. A second challenge with antigen 7 days after the first also induced an increase in audiological threshold (p < 0.05) and nystagmus. These results suggest that studies of repeated antigen challenge in actively sensitized animal models may increase our understanding of the pathophysiology of Ménière's disease.

Abstract
The messenger RNA level of several MAGE genes, some of which have been proven to encode tumor rejection antigens recognized by cytotoxic T lymphocytes, were examined in 41 benign and malignant lesions of the head and neck region. By a reverse transcription-polymerase chain reaction assay and Southern blot hybridization, MAGE-1, -2, -3, -4, and -6 genes were expressed in 25%, 41.7%, 33.3%, 8.3% and 33.3% of 12 non-squamous cell carcinomas, respectively. These tumors consisted of 6 papillary adenocarcinomas, 3 adenoid cystic carcinomas, 2 adenocarcinomas, and 1 mucoepidermoid tumor. Of 7 non-Hodgkin's lymphomas, one case from the oropharynx and 2 from the nasopharynx expressed for the MAGE-1 and MAGE-2 genes, respectively. In contrast, none of 12 benign tumors expressed any of these MAGE genes. Interestingly, of 10 other lesions including hyperplasia, keratosis, and ulcer, one histologically diagnosed as dysplasia expressed the MAGE-2, -3, -4, and -6 genes. These results suggest that the MAGE genes may be expressed in malignant tumors and precancerous lesions but not in benign tumors. In addition, non-squamous cell carcinomas may be suitable targets for specific immunotherapy against MAGE gene products.

Abstract
Substance P (SP) is a tachykinin involved in the regulation of inflammatory processes. To investigate a modulatory role of the neuropeptide SP in allergic inflammation, we studied its priming effect on human eosinophil chemotaxis and kinetic responses towards platelet activating factor (PAF) and recombinant human interleukin 5 (rhIL-5). Blood was obtained from normal subjects and eosinophils were separated by Percoll discontinuous density gradient centrifugation. High purification was obtained by negative selection procedure (CD16-beads) and the experiments were performed in a 48-well microchemotaxis Boyden chamber. In the present study we demonstrate a potent synergistic effect of 1OOnM dose of SP on the migratory function of human eosinophils stimulated by PAF and rhIL- 5. This synergism was chemotaxis specific and was abolished by NK-1 receptor antagonist (FK888). The results suggest that neurogenic stimuli may play a significant role in eosinophil infiltration via its priming effect on the cell.

Abstract
To investigate patients with Menière's disease and the association of cholinergic hyperreactivity, we performed muscarinic acetylcholine receptor assay using peripheral blood lymphocytes from patients with Menière's disease and non-dizzy, non-allergic control subjects. Cholinergic receptor maximal bindings (Bmax) and dissociation constants (Kd) were compared between the two groups, indicating the number and the affinities of the receptors, respectively. The receptor Bmax value in Meniére's patients during the remission state (108.6 +/- 51.2 fmol/l x 10(6) lymphocytes) was higher than that in normal controls (45.8 +/- 9.2 fmol/l x 10(6) lymphocytes) (p < 0.01). Furthermore, during an exacerbated state, Bmax was increased significantly (223.7 +/- 90.2 fmol/l x 10(6) lymphocytes) compared to the remission state (p < 0.01). In contrast, Kd values for the receptor did not differ between the two groups. These results suggest that patients with Menière's disease have cholinergic hyperreactivity, which may be further upregulated during a state of exacerbation due to an increase in the number of cholinergic receptors.

Abstract
A retrospective analysis was performed to investigate the radioprotective effects of azelastine against radiation dermatitis for patients with head and neck cancers. The effects of azelastine were studied in 19 patients with laryngeal cancers treated by irradiation. As controls, 29 patients with laryngeal cancers treated by irradiation without the administration of azelastine were studied. All patients were irradiated using 3 MV linac X-rays. Azelastine was administered orally twice a day. Moist desquamation was observed in four of 29 control patients whereas no such moist desquamation developed after the administration of azelastine. Two cases of moist desquamation that developed before the administration of azelastine regressed during irradiation in patients placed on azelastine. Radiotherapy was completed without interruption in all patients treated with azelastine. No severe side effects were observed. Azelastine, administered orally, was a safe drug and has the potential of improving skin tolerance in irradiation therapy.

Abstract
We examined the killing activity of transmigrated lymphokine-activated killer (LAK) cells and their surface molecules associated with both transendothelial migration and cytotoxicity, using human umbilical vein-derived endothelial cell (HUVEC) monolayers on fibronectin with gelatin separating the upper chamber from the lower chamber. Migratory LAK cells were significantly more cytotoxic to Daudi target cells, expressed more LFA-1, and were more likely to be positive for CD2, compared to those LAK cells not adherent to the HUVEC monolayer. In contrast, in the absence of the HUVEC monolayer, there was no difference in LAK activity between migratory and non-adherent LAK cells. These results indicate that the interaction between LAK cells and the HUVEC monolayer allows selective migration of LAK cells with cytotoxic activity that is enhanced with respect to some surface molecules.

Abstract
The MAGE genes encode certain tumor-associated antigens recognized by cytotoxic T lymphocytes. We investigated the expression of the MAGE-1, -2, -3, -4, -41, and -6 genes in 88 head-and-neck squamous-cell carcinomas (83 fresh tumor samples and 5 cell lines), using a reverse-transcription-polymerase-chain-reaction assay, followed by dot-blot hybridization with sequence-specific oligonucleotides and/or restriction enzyme-pattern analysis. The MAGE-1, -2, -3, -4, -41 and -6 genes were expressed at the mRNA level in 27, 34, 36, 22, 16 and 35, respectively, of 83 fresh tumor samples. At least one of these genes was expressed in 59 of the 83 samples. Neither non-tumor inflammatory cells nor normal tissues were positive for these genes. The MAGE-1 gene was expressed relatively frequently in SCC of the oropharynx, hypopharynx and maxillary sinus, but at lower rates in SCC of the larynx and of the tongue and oral cavity. MAGE-1 was frequently expressed in poorly differentiated SCC, somewhat less frequently in moderately differentiated SCC, and only infrequently in well-differentiated SCC. The expression levels of the other MAGE genes also varied with the anatomic site as well as the degree of differentiation. Our results suggest that specific immunotherapy against MAGE gene products may be useful for patients with head-and-neck carcinomas.

Abstract
Twenty-one cytotoxic T lymphocyte (CTL) clones or lines that killed autologous tumor cells, but not allogeneic tumor, K562, or Daudi cells, were established from fresh tumor-infiltrating lymphocytes of two individuals (HP-1 and HP-2) with head and neck cancer by limiting dilution in the presence of recombinant interleukin-2. Sixteen (76%) of these 21 clones or lines comprised CD4+ CTLs and the other five comprised CD8+ CTLs. These observations suggest that autologous tumor cell-specific CD4+ CD8- and CD4- CD8+ CTLs are present in vivo at the tumor site in head and neck cancer. Analysis of T cell receptor (TCR) gene arrangements in 20 of the 21 CTL isolates with reverse transcriptase and the polymerase chain reaction revealed that five of 12 and five of eight isolates from HP-1 and HP-2, respectively, were clones, the other isolates being lines comprised of two or more clones. Each CTL clone showed a different combination of V alpha and V beta gene expression, suggesting that more than five different tumor-associated antigens may be expressed on head and neck cancer cells. In spite of the diversity of TCR alpha beta combinations, TCR V alpha 1, V alpha 3, V alpha 8, V alpha 10, V beta 8, V beta 9, and V beta 17 were also frequently expressed in both patients. These data suggest that specific CTLs proliferate oligoclonally and contribute to the specific immune response against head and neck cancer in vivo.

Abstract
Pretreatment of squamous cell carcinoma (SCC) cells from four patients with low doses of cisplatin, carboplatin or 5-fluorouracil increased the susceptibility to lysis by autologous killer cells in vitro. Exposure of two SCC cell lines to low doses of these drugs increased the cell surface expression of both HLA class I and intercellular adhesion molecule-1 (ICAM-1). HLA class II, neural cell adhesion molecule and B7 were not expressed on the cell surface before or after such treatment. The results suggest that these drugs increase the susceptibility of tumor cells to autologous cell-mediated cytotoxicity, at least in part, by enhancing the expression of HLA class I and ICAM-1.

Abstract
We analysed the expression of melanoma antigen-encoding (MAGE) gene-1, -2, and -3 in 20 maxillary carcinomas consisting of two cell lines: freshly isolated cancer cells from specimens from 13 patients, and 5 biopsy specimens. The cells were subjected to reverse transcription by the polymerase chain reaction. Fourteen (70%) out of 20 maxillary carcinomas expressed at least one of the MAGE genes. In contrast, five control samples of inflammed mucosa from the maxillary sinus of patients with chronic sinusitis were all negative for the expression of these genes. Results indicated that patients with maxillary carcinoma may be good candidates for specific immunotherapy.

Abstract
Using head and neck tumors, we studied the role of HLA class I and DR antigens on tumor cells in cytotoxic T lymphocyte (CTL) induction. Expression of major histocompatibility complex (MHC) antigens was investigated by two-color flow cytometry analysis and for this study we used the tumor cells, over 50% of which expressed both HLA class I and DR antigens on their surface. In seven cases, tumor cells were divided into three groups according to the specificity of monoclonal antibodies (mAb) to MHC to study the role of MHC antigens on tumor cells in CTL induction: one was not blocked (MHC double-positive tumor), a second was blocked by anti-class I mAb (class-I-negative DR-positive tumor) and third was blocked by anti-DR mAb (class-I-positive DR-negative tumor). Subsequently, these tumors were used to stimulate an autologous mixed lymphocyte/tumor cell culture for 5 days (MLTC) followed by further cultivation with interleukin-2 for 12 days. The induced autologous tumor killer cells were most cytotoxic when non-treated tumors, which consist mainly of cells that are both HLA-class I and DR-positive, were used as stimulator cells. When the tumor cells blocked by anti-DR mAb were used as stimulators, autologous tumor killer activity was lower than that induced by tumor cells blocked by anti-class-I mAb. Moreover, cytolysis by autologous tumor killer cells induced by stimulation of non-treated tumor cells was blocked during the effector phase, 26.6%-42.3% and 32.7%-53.8% by anti-class-I and anti-DR mAb respectively, suggesting that majority of the autologous tumor killer cells are MHC-restricted CD8+ or CD4+ CTL. These results suggest that both MHC class I and class II antigens on head and neck tumor cells play a critical role in inducing CTL.

Abstract
In this study, we analyzed T cell receptor (TCR) gene rearrangements in tumor-infiltrating lymphocytes (TIL) freshly obtained from 15 patients with head and neck cancer using the reversely transcribed polymerase chain reaction (RT-PCR) method. These TILs showed preferential expression of V alpha 10, V alpha 8 and V alpha 1, detected in 13 (87%), 11 (73%), and 9 cases (60%), respectively. The TCRV beta gene revealed diversity without preferential usage. The head and neck region is exposed to bacteria and viruses, so it is possible that the tumor site can become infected and accumulate T cells involved in infection and inflammation. Therefore, we also investigated TCR gene usage in T cells infiltrating in chronic sinusitis mucosa to address the question of whether the V alpha 1, V alpha 8, and V alpha 10 subfamilies are characteristic in TIL from squamous cell carcinoma of head and neck. TCR V alpha 10 gene usage was also the most common in V alpha segment in T cells infiltrating the sinus mucosa, but V alpha 1 and V alpha 8 were not detected in the T cells in sinusitis. These results indicate that the V alpha 10 subfamily, the preferred T cell population in both TIL and T cells in inflammatory disease, might be involved mainly in inflammation or infection. On the other hand, V alpha 1 and V alpha 8 appear to be relatively specific populations for antitumor immunity in head and neck cancer.

Abstract
A cancer cell line named FS-1 was established from maxillary cancer of which histological diagnosis was well differentiated squamous cell carcinoma (SCC). The HLA class I typing showed that FS-1 expressed the same HLA class I antigens as those of the host lymphocytes. The chromosome analysis and nuclear DNA contents suggested that FS-1 was not a normal human cell. FS-1 is characteristic of SCC in that it grows adhesively on the surface of a culture flask. The structure of tumor tissue obtained from FS-1-transplanted nude mice is very much like the original tissue of SCC. The SCC-antigen was determined in the culture supernatant of FS-1. Autologous tumor killing activity was induced from peripheral blood lymphocytes of some patients suffering from head and neck SCC after mixed lymphocyte tumor culture with FS-1. Thus, FS-1 can serve as a useful allogeneic stimulator of SCC for induction of autologous tumor killing activity.

Abstract
Peripheral blood lymphocytes obtained from 2 patients with hypopharyngeal cancer were cultured with mitomycin C treated autologous tumor cells (autologous MLTC) for 10 days and further cultured with recombinant interleukin 2 (rIL-2). In one case 10-day MLTC induced increase of CD25-positive lymphocyte count, indicating that IL-2 receptors were expressed dominantly by the autologous tumor stimulation, and further culture with rIL-2 differentiated killing activity against autologous tumor cells. In the other case, however, MLTC alone induced killing activity against autologous tumor cells, indicating that the tumor cells from this patient might possess stimulatory activity sufficient to induce mature killer cells. Electron microscopic observation of the morphological features of lymphocytes cultured for 10 days revealed mostly small lymphocytes with low incidence of cytoplasmic granules. Further culture with rIL-2, however, induced slightly larger lymphocytes with well-developed microvilli, and cytoplasmic granules were found in many of the cells. Lymphokine activated killer (LAK) cells induced by culture of lymphocytes with rIL-2 alone were much larger and had long microvilli and abundant cytoplasmic granules, and were apparently morphologically different from the killer cells initiated by MLTC. The small lymphocytes induced by autologous MLTC alone might be autologous tumor specific cytotoxic T lymphocytes (CTL) and/or CTL precursors. Further culture with rIL-2 induced maturation of the CTL. However, the nature of the cytoplasmic granules remains obscure.

Abstract
Peripheral blood lymphocytes were cultured for 5 days with allogeneic tumor cells (allogeneic mixed lymphocyte/tumor cell culture), and subsequently cultured with recombinant interleukin-2 for 12 days. These cultured cells were found to be cytotoxic to autologous tumor cells. Results of two-color analysis using monoclonal antibodies to cell markers showed that more than 80% of their cultured cells were CD3+ cells, and CD4+ cells showed a higher distribution than CD8+ cells. However, CD8+ cells had a much higher killing activity with autologous tumor than did CD4+ cells, when estimated by an elimination study using monoclonal antibodies to T cell phenotypes and complement. The "cold-target" inhibition test showed that the cytotoxicity of these cells for autologous tumor cells was inhibited by unlabeled autologous tumor cells but not by unlabeled stimulator cells. Furthermore, about 40% of the cytotoxicity was suppressed by blocking of HLA class I antigen with a monoclonal antibody on autologous tumor cells. Thus, cytotoxic activity of lymphocytes to autologous tumor restricted by target cell HLA class I antigen is possibly induced by allogeneic tumor-stimulation.

Abstract
The proliferative response of T cells cultured with autologous non-T cells is known as the autologous mixed lymphocyte reaction (AMLR). The AMLR in patients with head and neck tumors was found to be significantly decreased in comparison with that in normal donors and patients without evidence of recurrent disease more than 3 years after treatment. Responder T cells in AMLR were CD4+ T cells but not CD8+ T cells. In one patient, AMLR were performed between lymphocytes in condition with tumor burden and those in condition with tumor free by using cryopreserved lymphocytes. T cells in tumor burden state poorly responded to both of these non-T cells. On the other hand, T cell in tumor free state vigorously responded to non-T cells in the same state, but not to non-T cells in tumor burden state. These data indicated that impairment of AMLR in patients with cancer was due to deficit of both responder T cells and autologous stimulator non-T cells.

Abstract
Peripheral blood lymphocytes drawn by leukapheresis using Haemonetics V50 were mixed and cultured with autologous or allogeneic tumour cell line to activate killer cells by tumour antigenic stimulation, and further with recombinant interleukin-2 (rIL-2). Killer cells were intra-arterially infused, as a primary therapy, in 5 patients with maxillary and one with lingual cancer (squamous cell carcinoma). Effects on reduction of primary tumour size were significantly high without any severe side effects. The effects were interpreted mainly by direct day-by-day observation of the site, findings of CT and histology. Histological findings of the tissue obtained by surgical operation performed after adoptive immunotherapy were remarkable changes, such as infiltration of lymphoid cells around the cancer nets, degeneration of cancer cells, infiltration of scavenger macrophages (giant cells) and so on. The results suggested that adoptive immunotherapy by the killer cells can be a powerful treatment to bring the cancer under control, in with combination of other therapies.

Abstract
For clinical application of adoptive immunotherapy, it is necessary to prepare a sufficient number of autologous tumor specific effector cells. A large amount of peripheral blood lymphocytes was obtained by leukapheresis using a Heamonetics V50 pheresis system. Autologous tumor- and lymphokine-activated killer (ATLAK) cells were induced by autologous mixed lymphocyte tumor cell culture (autologous MLTC) and further activation with recombinant interleukin-2 (rIL-2). Another problem was the difficulty of obtaining a sufficient number of highly activated effector cells to reach the target tumor tissue. Direct infusion of effector cells into a feeding artery was effective for cell accumulation in the target. ATLAK cells were infused into maxillary artery in 4 patients with maxillary squamous cell carcinoma. The results indicated that the therapy was effective for reduction of the tumor mass. After immunotherapy, surgery was performed and the tissues were histologically examined. Degenerated tumor cells and intensive infiltration by mononuclear cells and macrophages were seen in the surrounding fibrous tissue. However, the quantity of fresh autologous tumor cells available from open biopsy was limited. Allogeneic cultured tumor cell line was used as stimulator of lymphocytes instead of autologous tumor cells. The killing activity of the allogeneic tumor and lymphokine activated killer (Allo-TLAK) cells was significantly induced against the autologous tumor cells. Antitumor effect was observed in 5 out of 9 patients. Side effects were minor, such as slight fever and blood eosinophilia, which may be due to the rIL-2 function. These results indicate that this method of therapy is an effective form of adoptive immunotherapy.

Abstract
Cytotoxicity was induced in lymphocytes (CL) from 10 out of 15 patients by autologous mixed lymphocyte tumor cell culture and further cultivation with recombinant interleukin-2. In cells from 3 of the 10 patients, cytotoxicity was suppressed by more than 50% when autologous peripheral blood mononuclear cells (PBMC) from the patients with large tumors were added to the autologous killing system. The cells responsible for suppressing the cytotoxicity in the effector phase were adherent or nonadherent to plastic depending on the patient examined. The T cell fraction from 1 patient significantly suppressed the cytotoxic activity, and this suppression was seen only in the autologous system. On the other hand, plastic adherent cells but not T cells from PBMC of 2 subjects suppressed the cytotoxic activity of CL. The reason why the main cell population suppressing the CL activity differed among the patients is unclear. However, the findings that the suppression was mostly abrogated following resection of the tumor mass suggested that suppressor cells, either of macrophage lineage or T cells, are induced in patients with a large tumor mass. This speculation is supported by the finding that the PBMC from a patient with tumor recurrence regained the suppressive activity.

Abstract
Tonsillar (TL) and peripheral blood lymphocytes (PBL) from patients with pustulosis palmaris et plantaris (PPP) or recurrent tonsillitis (RT) were analysed for their proliferative response of T-cells upon stimulation with non-T-cells in the autologous mixed lymphocyte reaction (AMLR). TL and PBL from the same donor were cultured in the AMLR for up to 7 days. Maximum proliferation was observed after a 6-day culture in PBL, whereas that of TL was observed on the 3rd day of the culture. It was also observed that the AMLR of TL in patients with PPP was significantly (p less than 0.01) lower than in patients with RT. On the other hand, it has previously been proved by an immunofluorescence study that there is an identical antigenicity between tonsillar epithelium and skin. From this result, a blastoid transformation study of TL and PBL from patients with PPP was performed by using homologous or autologous skin extracts. Both homologous and autologous skin extract induced blastoid transformation of TL but PBL scarcely responded. These results may support the opinion that an auto-immunological mechanism may take part in the onset of PPP.

Abstract
Antigenic differences between primary tumors and their cervical lymph node metastases of 12 patients with head and neck cancers were examined by measuring their sensitivity to cytotoxic lymphocytes (CL). Cytotoxicity was induced by autologous mixed lymphocyte (CL). Cytotoxicity was induced by autologous mixed lymphocyte tumor cell culture (MLTC), and further cultivation with recombinant interleukin-2 (rIL-2). The effector cells which were used in this study consisted of OKT3+8+ and OKT3+4+ subpopulations. Their cytotoxic nature was different from lymphokine activated killer cell (LAK cell) activity. Cytotoxicity of CLs stimulated by autologous primary tumor cells (CLP) was observed in 7 out of 12 patients (58.3%). In contrast, cytotoxicity of CLs stimulated by metastatic tumor cells (CLM) was observed in 4 out of 12 patients (33.3%). In the cases in which both CLP and CLM were successfully induced, cross-reactivity tests and cold target inhibition tests were performed. These results suggested that a reduction in immunogenicity had occurred at the metastatic site, and sensitivity against autologous CL was different between primary and metastatic tumor cells.
