Abstract
BACKGROUND From 1999, Norwegian guidelines recommend two escalated (esc) BEACOPP (bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine, prednisolone) followed by six standard (s) BEACOPP for patients with advanced-stage classical Hodgkin lymphoma (HL) with an international prognostic score (IPS) ≥ 4. We evaluated retrospectively the experience with this recommendation at the Norwegian Radium Hospital, also including all IPS 3 patients treated with the same regimen. PATIENTS AND METHODS Forty-seven patients were treated between June 1999 and December 2008. IPS was 3 in 10 patients and ≥ 4 in 37. RESULTS Thirty-five patients received eight cycles of BEACOPP, 12 patients received one to six cycles only, mainly due to toxicity. Sixty percent of patients had dose reductions. With median follow-up of survivors of 89 months, 5-year progression-free and overall survival are 84% [95% confidence interval (CI) 73% to 95%] and 91% (95% CI 82% to 100%), respectively. Toxicity was considerable with grade 3 or more infections/febrile neutropenia in 66% of patients, including one death and three cases of Pneumocystis jiroveci pneumonia. Of note, 10 patients (21%) experienced symptomatic aseptic osteonecrosis, of whom 3 have had hip replacement surgery after treatment. CONCLUSION Two escBEACOPP plus six sBEACOPP is efficacious in advanced-stage high-risk HL. We document a high incidence of aseptic bone necrosis, possibly related to prednisolone.

Abstract
Reduced-intensity conditioning (RIC) allo-SCT is a potentially curative treatment approach for patients with relapsed Hodgkin's or non-Hodgkin's lymphoma. In the present study, 37 patients underwent RIC allo-SCT after induction treatment with EPOCH-F(R) using a novel form of dual-agent immunosuppression for GVHD prophylaxis with CsA and sirolimus. With a median follow-up of 28 months among survivors, the probability for OS at 3 and 5 years was 56%. Treatment-related mortality was 16% at day +100 and 30% after 1 year of transplant. Acute GVHD grades II-IV developed in 38% of patients, suggesting that the regimen consisting of CsA and an ultra-short course of sirolimus is effective in the prevention of acute GVHD.

Abstract
There is no consensus on the optimal chemotherapy regimen for Hodgkin's lymphoma patients > or = 60 years. We present our institution's results of 5 years, using CHOP-21 as standard for this patient group. Twenty-nine patients with a median age of 71 years (range, 60 - 91) were included in this cohort. Fifty-five percent had known co-morbidities. Stage I/IIA patients (38%) were treated with 2 - 4 cycles of CHOP followed by radiotherapy. Stage IIB - IV patients (62%) received 6 - 8 cycles of CHOP and for the majority (13/18 pts) no radiotherapy. Two treatment-related deaths occurred. Febrile neutropenia was the most common toxicity (31%). The complete response rate after CHOP +/- radiotherapy was 93%. With a median follow-up of 41 months, five patients have relapsed and four have died from Hodgkin's lymphoma. So far, no relapses have occurred after 2 years from the end of therapy. Overall survival and progression-free survival at 3 years were 79% and 76%, respectively. We conclude that CHOP-21 is a well-tolerated and effective treatment for elderly patients with Hodgkin's lymphoma.

Abstract
BACKGROUND A graft-versus-lymphoma effect against diffuse large B-cell lymphoma (DLBCL) is inferred by sustained relapse-free survival after allogeneic stem-cell transplantation; however, there are limited data on a direct graft-versus-lymphoma effect against DLBCL following immunotherapeutic intervention by either withdrawal of immunosuppression or donor lymphocyte infusion (DLI). MATERIALS AND METHODS An analysis was carried out to determine whether a direct graft-versus-lymphoma effect exists against DLBCL. The analysis was restricted to patients with DLBCL, who were either not in complete remission at day +100 after allogeneic stem-cell transplantation or subsequently relapsed beyond this time point. RESULTS Fifteen patients were identified as either not in complete remission (n = 13) at their day +100 evaluation or subsequently relapsed (n = 2) and were assessed for subsequent responses after withdrawal of immunosuppression or DLI. Eleven patients were treated with either withdrawal of immunosuppression (n = 10) or a DLI (n = 1) alone; four patients received chemotherapy with DLI to reduce tumor bulk. Nine (60%) patients subsequently responded (complete = 8, partial = 1). Six responses occurred after withdrawal of immunosuppression alone. Six patients are alive (range 42-83+ months) in complete remission without further treatment. CONCLUSION The demonstration of sustained complete remission following immunotherapeutic intervention provides direct evidence of a graft-versus-lymphoma effect against DLBCL.

Abstract
This study reports on oncology professionals' knowledge and attitude toward complementary and alternative medicines (CAM), classified according to their primary application as complementary or alternative methods. In June 2002, we conducted a national, multicentre survey of 828 Norwegian oncologists, nurses, clerks and therapeutic radiographers. A response rate of 61% was achieved. Only a few physicians (4%) described their reactions to alternative medicine as positive compared with nurses (33%), therapeutic radiographers (32%) and clerks (55%) (P<0.0001). Females showed a more positive view than males (33% versus 14%, P<0.0001). More participants expressed a positive attitude to complementary versus alternative medicines. Most respondents regarded healing by hand or prayer, homeopathy, and Iscador (mistletoe) as alternative therapies. In contrast, most respondents classified acupuncture, meditation, reflexology, music/art-therapy, aromatherapy and massage as complementary therapies. This survey demonstrates major differences, by gender as well as oncology health profession in views about and the classification of various CAM methods.

Abstract
GOALS OF WORK It is well documented that an increasing proportion of cancer patients today use complementary and alternative medicine, mostly alongside conventional therapies. This study investigates the use of complementary and alternative medicine among oncology health workers and the reported effects. PATIENTS AND METHODS In June 2002, we conducted a national multicentre survey including 828 Norwegian oncologists, nurses, clerks and therapeutic radiographers. The response rate was 61.5%. MAIN RESULTS We found that females were more often users of both complementary and alternative methods than males (39% versus 15% and 47% versus 17%) and that few oncologists had tried such treatments compared to nurses, therapeutic radiographers and clerks (20/12% versus 50/40%, 41/33%,and 31/50%). Interestingly, the majority of those who had tried unconventional methods reported some or very good effects. Acupuncture, homeopathy, aromatherapy and massage were the most popular therapies. Sub-group analyses including only oncologists showed that female physicians were more often users of both complementary and alternative methods compared to males (33% versus 12%, 25% versus 3%). Moreover, participants below the age of 35 years and Christians more often reported use. CONCLUSIONS This survey demonstrates that significant proportion of oncology health workers in Norway have used non-proven therapies and that most have had a positive experience. Differences in use is highly dependent on gender, profession, age and religion.

Abstract
The aim of this study was to investigate the late effects of ABMT on the immune system with regard to protective humoral immunity against common antigens and responses to recall antigens (vaccines). The vaccines were given according to EBMT guidelines from 1995. The protocol included 35 patients with malignant lymphoma in CR 4-10 years after ABMT, and 35 controls. The results show that prior to ABMT the proportion of patients with protective immunity against poliomyelitis, tetanus and diphtheria was similar to that of controls. At study entry 4-10 years after ABMT, the proportion of patients with protective immunity against poliomyelitis and diphtheria was reduced, while all patients maintained protection against tetanus. A significant decrease in geometric mean antibody concentrations or titres was observed against all three antigens during this period. Serum levels of antibodies against different pneumococcal serotypes were lower in the patients than in the controls prior to vaccination. The responses to pneumococcal vaccination, which is considered to be a T cell-independent vaccine, were studied. Unlike controls, a minority of patients achieved protective levels of antibodies after a single vaccination. Despite persistent levels of protective antibodies in many patients post ABMT, secondary booster responses after one vaccination with T cell-dependent vaccines (tetanus, diphtheria and polio) were absent. In conclusion, this study shows that post ABMT, a full re-vaccination program was necessary to mount responses comparable to those observed after a single vaccination in controls.

Abstract
Thirty-one previously untreated patients with follicular low-grade B-cell non-Hodgkin's lymphoma expressing the CD20 antigen were treated with iodine-131 tositumomab therapy between 1996 and 1998. The therapy led to a temporary depletion of peripheral blood B-lymphocytes. Recovery of B-cells occurred in most cases by 3 to 6 months and in all patients by 12 months posttherapy. A temporary decline in T-cell subpopulations, but no reduction in serum immunoglobulin levels, could be observed. ELISA techniques were used to detect specific antibodies against rubella, mumps, varicella zoster, measles, and tetanus. Almost all patients remained seropositive against the different antigens during the 1- to 2-year follow-up. No significant reduction in antibody concentrations to tetanus or measles could be detected. The data show that acquired humoral immunity against common antigens appears to be preserved despite a temporary loss of B-lymphocytes.

Abstract
OBJECTIVE To determine clinical outcomes of primary intracapsular cataract surgery with and without implantation of anterior chamber lenses. DESIGN A multicenter randomized clinical trial. PARTICIPANTS One thousand two hundred twenty-nine male and female patients 40-75 years of age with senile cataract. METHODS Study patients were recruited from screening eye camps and outpatient clinics. Randomization to the two treatment groups was performed after screening for predetermined inclusion and exclusion criteria. Demographics, visual acuity, intraocular pressures, and corneal endothelial cell data were recorded before surgery and at 6 weeks, 12 months, and 24 months after surgery. Monitoring of the study was secured by a standardized image documentation procedure on all patients using the IMAGEnet digital imaging system. Analysis of corneal endothelial cell images was performed with the Cell Soft software (Topcon Corporation, Japan). MAIN OUTCOME MEASURES Visual acuity and central corneal endothelial cell loss. RESULTS The patients were randomized to intraocular lens (IOL; n = 616) and no IOL (n = 613) implantation. Surgical complications were reported in 177 (14.4%) patients (IOL = 14.8%; no IOL = 14.0%). The most frequent complication observed was vitreous loss which occurred in 10.3% of eyes (IOL = 11.2%; no IOL = 9.5%). At the final examination (2 years after surgery), 88% of the operated eyes had a best corrected vision of 6/18 or better (IOL = 88.8%; no IOL = 86.6%). Analysis of corneal endothelial cell data showed a small but significantly greater cell loss 6 weeks after surgery in eyes with IOL compared with those without IOL, but no overall difference was found between the treatment groups in the long term follow-up. CONCLUSIONS The findings indicate that there is a rationale for the use of anterior chamber intraocular lenses in primary intracapsular cataract surgery.

Abstract
In February 1997 a questionnaire on alternative medicine was distributed to 172 physicians, 374 nurses and 96 clerks, all employed in hospitals in the northern part of Norway. A response rate of 57% was achieved. The aim of the study was to compare different health professions regarding views on and use of alternative medicine. Among all respondents 56% described themselves as having a positive attitude towards alternative medicine (16% of the physicians, 71% of the nurses and 72% of the clerks). Twelve percent of physicians, 32% of nurses and 46% of clerks had been using alternative medicine. Female physicians and female nurses showed a more positive attitude and were more frequent users of alternative medicine than their male counterparts. Physicians had confidence in acupuncture, herbs and diets, mainly as treatment of muscle-skeletal disorders, and migraine. Nurses and clerks on the other hand tended to believe in various alternative methods against a broad range of disorders. Female physicians and nurses emphasised the importance of more information, knowledge and openness towards alternative treatments more than their male counterparts. They also believed that traditional medicine could benefit from adopting principles from alternative medicine.

Abstract
The aim of the present study was to investigate whether the early changes in the immune system observed after ABMT would persist over years. Eighty-five patients with malignant lymphoma were treated with ABMT in Norway from 1987 until 1993. Of the 46 patients in CR by 1997, 36 were enrolled in our study. Median time from ABMT was 5 years (4-10 years). Immunophenotyping showed an increase in the median number of B cells (0.35 x 109/l in patients vs 0.28 x 109/l in controls), and a decrease in T cells (1.08 vs 1.35 x 109/l). Furthermore, a lower median count of CD4+ T cells (0.54 x 109/l in patients vs0.87 x 109/l in controls) resulted in reduced CD4/CD8 ratios (0.8 in patients vs 1.6 in controls). The subgroup of CD4+ T cells expressing the 'naive' phenotype CD45RA was 19.5% in patients vs 38% in controls. In contrast, the fraction expressing the 'memory' phenotype CD45RO was higher in the ABMT group (76% vs 54%). When stimulated, larger fractions of CD3+CD4+ cells in patients produced IFN-gamma (32% vs 16%) or IL-4 (7% vs 1%) compared to controls; thus a differentiation into the functionally separate subgroups Th1 and Th2, with a dominant Th2 response. Our data further suggest that the decrease in CD4+ T cell counts and the imbalance between CD45RA+ and CD45RO+ subsets persists 4-10 years after ABMT.

Abstract
Increase in UV-B radiation, due to stratospheric ozone depletion, is an environmental threat to arctic ecosystems and the health of their inhabitants. The aims of this longitudinal study are to provide basic population risk perception data related to UV-B and ozone depletion, and to compare the UV-B risk perception over time and with risk perception related to other objects and occurrences. A survey questionnaire, calling for a total of 118 judgments, measures risk perception, worries, and anticipated consequences. In the 1996 study, 143 persons completed the questionnaire, 34 of whom belong to the indigenous Sami population. Risk perception and the possibility of protecting oneself against 13 risks were measured on 7-point scales. The mean risk rating for depletion of the ozone layer and UV-B radiation was moderate to high. The possibility of protection was rated relatively low. Women, the youngest, and respondents in the North were most worried and perceived the highest risks. The Sami respondents are less worried and perceive a lower risk, a realistic short-term evaluation due to their protection by pigment in the skin and their clothing habits.

Abstract
In the past high-dose chemotherapy with autologous stem cell support in the treatment of certain types of cancer, was centralized to two hospitals in Norway. Almost three years ago it was decided that the treatment should be offered by all five university hospitals. In the northernmost university hospital of Norway, Tromsø, peripheral stem cells were harvested from 29 patients after successful mobilization with chemotherapy and granulocyte colony-stimulating factor (G-CSF). After high-dose chemotherapy, more than 2 x 10(6) CD34-positive stem cells/kg were transplanted in 24 patients and a sign of reconstitution of bone marrow function was achieved with mean time for neutrophils > 0.5x10(9)/l, 9.8 days and for platelets > 20x10(9)/l, 10.8 days. No treatment-related deaths have occurred. Transplantation of selected CD34-positive stem cells has been performed in one patient. Recovery was comparable to the recovery of patients who had undergone transplantation with unselected products. This indicates that even small centres performing as few as ten procedures per year may offer high-dose chemotherapy with autologous stem cell support safely and successfully.

Abstract
Since 1994, 17 breast cancer patients and 16 lymphoma patients have been treated at the Norwegian Radium Hospital with high-dose therapy supported by autologous peripheral progenitor cells. All the patients were given granulocyte colony stimulating factor in the recovery phase after cytotoxic treatment in order to mobilize and harvest peripheral progenitor cells. Aphareses were successful in all patients and the mean number of CD34 cells reinfused per kilo body weight was 7.05 x 10(6) for the lymphoma patients and 11.1 x 10(6) for the breast cancer patients. The mean time to recover > or = 0.5 x 10(9)/l granulocytes and > or = 20 x 10(9)/l platelets after reinfusion of stem cells was 10 days and 11.7 days respectively for the lymphoma patients, while the breast cancer patients engrafted at day 8.6 and day 9.3. No severe treatment-related complications were observed.

Abstract
The palindromic dodecamer [d(GCCGATATCGGC)]2 has been titrated by Hg(ClO4)2 in order to study sequence dependent HgII ion interactions. The titration pattern as monitored by 1D and 2D 1H NMR is consistent with a transition to a new conformer of the dodecamer induced by HgII ions. At intermediate stages of the titration, the proton signals from the new conformer coexist with those of the original one, indicating slow exchange between the two forms on the NMR timescale. The data clearly show that there is no major alteration in the secondary structure, e.g. B-->Z-form or duplex-->hairpin transition. The intra- and inter-residue sequential walk is completed except for a break between T6 and A7. At a concentration level r = [HgII]/[nucleobase] < 0.20 all four central imino signals are present. This definitely excludes thymine N3 as a possible mercuration site. In the imino region of the spectra HgII ions induce a large upfield shift of the thymine imino resonance T8-N3H, while the other thymine resonance T6-N3H is unperturbed. The guanine imino signal G4-N1H shows a large downfield ring current shift caused by major conformational changes in the duplex. The complete titration experiment indicates that mercury, initially, binds selectively to the A5'-T8 base pair. A tentative model is proposed where mercury is cross-linking the two strands via thymine T8-O4 and the deprotonated amino group of the complementary adenine base A5'.

Abstract
The new human-human hybridoma TrD3 secretes a cytotoxic IgM mAb, which reacted with 28 of a panel of 56 HLA-typed lymphoblastoid cells. All 28 TrD3+ cells expressed the HLA-B supertype Bw6, whereas 10 Bw6+ cells were not recognized by the mAb. None of the 17 Bw4 homozygous cells were positive with TrD3. Thus, TrD3 divided the Bw6+ HLA-B specificities of the cell lines into two subgroups, namely, Bw6+TrD3+ and Bw6+TrD3-, and therefore defines a new HLA-B supertype. TrD3 reacted strongly with some B8+ cell lines and weakly or not at all with others, suggesting a new split of HLA-B8. Compared with cell lines, TrD3 reacted more weakly with freshly isolated T cells from blood. The Bw6-specific rat mAb SFR8-B6 partially blocked the binding of 125I-labeled TrD3 to a Bw6+ cell line. By using cell lines transfected with hybrid genes between HLA-B7 (Bw6+) and HLA-B27 (Bw6-) as targets in flow cytometry, critical residues for the TrD3 epitope could be mapped to the amino acid region 24-62 of the HLA class-I alpha 1 domain. Comparison of deduced amino acid sequences of TrD3-positive and -negative cells indicated that a tryptophane residue at position 95 destroyed the TrD3 epitope, and that one or more of the residues in positions 24, 45, and 46 may be critical, suggesting that it is a discontinuous epitope. It is notable that none of these residues are located on alpha-helixes.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
We here report two human-human hybridoma antibodies: TrB50 (IgG) and TrE11 (IgM), derived from the same donor. They displayed an identical reaction pattern with 76 Epstein-Barr virus-transformed cell lines. Of these, 29 lines were completely HLA-typed and both antibodies recognized all cells expressing DPwl (six lines), DPw3 (five lines), or DPw5 (three lines). In addition, they bound to one out of four DPw2+ cells and three out of four DPblank+ cells. This specificity correlated strikingly with a characteristic DP beta amino acid sequence (DEAV) at positions 84-87 that had been determined by others. Binding of 125I-labeled TrB50 to lymphoblastoid cells was inhibited by unlabeled IVA-12 (anti-DR + DP monomorphic) and by TrE11. Furthermore, antigens in lysates from TrB50+TrE11+ cells cross-linked TrB50 and TrE11 to the monomorphic anti-DP monoclonal antibody B7/21. Collectively the data provide strong evidence that the epitopes reside on DP molecules. TrE11 can be used to type for this DP beta supertypic specificity by microcytotoxicity using isolated blood B lymphocytes as targets or by a rosette assay directly on whole blood.

Abstract
TrC7 is a cytotoxic IgM human-human hybridoma anti-HLA Ab. Its reaction pattern with a panel of 48 HLA-typed EBV-transformed cell lines and PBMC from 348 HLA-typed individuals correlated precisely with expression of HLA-A29. TrC7 did not react with HLA-A30, -31, -32 or -w33, which, like A29, are splits of Aw19.

Abstract
Epstein-Barr virus (EBV) transformed B-cells from patients with multiple sclerosis (MS) and healthy controls were analysed for reactivity with the HLA-DQ-specific human-human hybridoma Ab TrB12 (anti-DQw6 + DQw8 + DQw9) by indirect immunofluorescence (IIF). Positive results were obtained with 34 out of 35 MS patients (97.1%) and 79 out of 106 controls (74.5%) (p less than 0.005, RR = 11.6). Thus, DQ molecules that express the TrB12 epitope may contribute to the susceptibility to develop MS.

Abstract
We have generated two IgG human-human hybridoma Abs, TrG6 and TrC5, that define subsets of HLA-DQ. TrG6 combined selectively with lymphoblastoid cell lines that expressed DQw1 or DQw4. By sequential immunoprecipitation, competition with other mAbs of defined specificity for binding to antigen, and experiments where HLA antigens from cell lysates crosslinked pairs of mAbs, it was established that TrG6 bound a DQ-molecule. mAb TrC5 specifically recognized DQw2+DR3+ and DQw7+DR5+ cells. The reaction pattern of TrC5 with HLA-loss mutants indicated that TrC5 bound to DQw2 of the DQw2+DR3+ haplotype. Antigens in lysate from DQw7+DR5+ cells crosslinked TrC5 to the murine mAbs Tü22 (anti-DQ monomorphic) and IVD-12 (anti-DQw7 + DQw8 + DQw9), demonstrating that on these cells the TrC5 epitope is located on DQw7 molecules. Lysates from DQw7+DR5+/DQw4+DRw8+ heterozygous cells crosslinked TrG6 and TrC5, and available evidence indicated that the epitopes defined by these two mAbs were expressed by the transcomplementing DQ-molecule DQw7 alpha/DQw4 beta, where the DQw7 alpha chain specifies epitope TrC5 and the DQw4 beta chain specifies epitope TrG6. Taken together with published nucleotide sequences of DQ alpha and beta genes, our data are consistent with the conclusion that the amino acids at positions 69 and/or 75 of the DQ alpha chain of DQw2+DR3+ and DQw7+DR5+ haplotypes are critical for epitope TrC5. The previously reported human-human hybridoma Ab TrB12 reacts with DQw6, DQw8, and DQw9. The specificity of the murine mAb IIB3 is similar to that of TrB12, but, unlike TrB12, IIB3 also binds DQw4+ cells.

Abstract
Assessment of medical technologies is an important topic in health services research. The article describes a special aspect of user-related evaluation of devices in Norway. The Norwegian hospitals have high technical capacity and standards but the equipment is not assessed before being purchased by the hospitals. The idealistic rules for technology assessment are of no use in practical situations. The health authorities in Norway have established a national database for users' experiences and hazard registration. When assessing equipment, it is necessary to take into consideration the situation and the people handling the devices. A system-analytic perspective is proposed for better understanding. The database for experiences with devices stores information concerning maintenance, repair and service, i.e. the whole life history of the medical technology. All this information will be accessible for the hospitals through electronic mail or electronic meetings.

Abstract
TrH6 is a new human-human hybridoma antibody (Ab) of IgM, lambda isotype. At concentrations of 17-5000 ng IgM/ml, TrH6 killed twelve out of fourteen lymphoblastoid cell lines that expressed DRw52, but none of the nine DRw53 homozygous lines. Both DRw52+ cells (LUY, TAB) not killed by TrH6 were DR8+, suggesting that these lines express a structural variant of DRw52 linked to DR8. The murine cytotoxic DRw52-specific mAb 7.3.19.1 (Koning et al. 1984) exhibited the same pattern of reactivity with DRw52+ cells as TrH6. However, unlike TrH6, 7.3.19.1 cross-reacted weakly with two DR7+DRw53+ homozygous cell lines, suggesting that the TrH6 epitope has a more limited distribution. The reactions with a panel of cells with known deletions in the HLA-region supported the conclusion that TrH6 is specific for DRw52. Further evidence was obtained in a competition RIA, where the murine mAbs L243 (anti-DR monomorphic) and 7.3.19.1 (anti-DRw52) inhibited binding of radiolabeled TrH6 to DRw52 homozygous cells. TrH6-coated magnetic beads provided a simple rosette-assay for typing of "buffy-coat" leukocytes for the TrH6 epitope.

Abstract
The authors of the paper argue that Norway's national health service, despite public perceptions, is both inexpensive and technologically advanced. Norway has a highly regulated medical system at both the national and local levels, and many distribution issues take the form of political debate. As a result, the authors believe that medical care and equipment is equitably distributed, but perhaps over-densely, throughout the country. Although the overall picture is optimistic, there is some concern that technologies, health care priorities, and decision-making processes should be more carefully examined by consensus conferences, advisory groups, and experts in technology assessment.

Abstract
A human-human IgM (lambda) hybridoma antibody (called Tr7E2) was constructed by fusing Epstein-Barr virus-transformed cells from a multiparous woman with the human fusion partner KR12. By eosin exclusion microcytotoxicity the monoclonal antibody killed 12 of 13 human leukocyte antigen DQw1-bearing lymphoblastoid cells. No reaction was seen with any of 19 DQw1-negative cells. The single DQw1+ cell line that was not killed by Tr7E2 was the homozygous cell called 9WS 806 TAB (DR8,8; DQw1,1) of Japanese origin. The radioimmunoassay indicated that this result was probably not because of a decreased expression by this cell of DQ antigens, and these cells were killed by the mouse monoclonal antibody Genox3.53G2a5, reported to be specific for DQw1. Thus, the Tr7E2- cell line TAB probably expresses a novel structural DQw1 variant. Of 213 Norwegians, 107 were Tr7E2+ Genox+; none expressed only one of these epitopes. The putative split is, therefore, probably very rare in this population. Monodisperse magnetic polymer beads coated with Tr7E2 formed rosettes selectively with peripheral blood mononuclear cells from DQw1-positive individuals, suggesting a new approach to typing for class II antigens.

Abstract
We have constructed an IgG, kappa human--human hybridoma Ab(TrB12), which precipitates a molecule consisting of two polypeptides of about 33 and 27 kD in size. TrB12 reacted with; (1) 7 out of 10 DQw1-positive cell lines in IIF, and all 10 in a rosette-assay; (2) 5 out of 12 DQw3-positive cells, both in IIF and the rosette-assay; (3) none of 4 DQw2 homozygous cells. Detergent cell lysate of DQw1 homozygous cell lines contained antigens that cross-linked the mouse monoclonal antibody Genox 353 G2a-5 (anti-DQw1) and TrB12. TrB12 competed with the mouse DQw3-specific monoclonal antibody IVD-12 for binding to DQw3 homozygous cells. The data imply that the TrB12 epitope is associated with molecules that carry DQw1 and DQw3 serological specificities. By radioimmunoassay, TrB12 and the mouse monoclonal antibody IIB3 divided both DQw1- and DQw3- bearing cell lines into three phenotypic groups: (1) TrB12+IIB3hi, (2) TrB12-IIB3lo, and (3) TrB12-IIB3-. For DQw1 the results suggest that the first two groups represent structural variants but the third group may reflect low expression of DQw1. For DQw3 the evidence suggests that all three phenotypes represent structural variants. DQw3 has previously been divided into two serologically defined alleles, TA10+IIB3- and TA10-IIB3+. The TrB12+IIB3hi and TrB12-IIB3lo variants of DQw3 described in this study probably represent novel subgroups of the TA10-IIB3+ allele.

Abstract
Mononuclear blood cells from a multiparous woman were transformed with Epstein Barr virus, and a cell line (Tr2D8) producing anti-HLA antibody was obtained. This cell line was immortalized by hybridization to the human fusion partners KR4 and KR12. While the EBV line died after 7 months, the hybridomas have remained stable for 13 months. The EBV line supernatant (40 micrograms IgM/ml) lysed peripheral blood mononuclear cells (PBMC) bearing B15, B17, B5 and B35. Consistent lysis of B18 bearing cells was only observed with lymphoblastoid cell lines. The supernatant from the Tr2D8 (EBV line X KR4) hybridoma (2.7 micrograms IgM/ml) only lysed B15 bearing PBMC. At a concentration of 13.5 micrograms IgM/ml, the hybridoma antibody lysed lymphoblastoid cell lines bearing B15, B17, B5, B35 and B18.

Abstract
IgG antibodies to neutrophil polymorphonuclear cells (PMNs) were detected by a simple indirect immunofluorescence method that did not require chemical or enzymatic modification of the cells. Based on recent information about the human PMN Fc gamma-receptor, nonspecific binding of IgG to PMNs was virtually completely prevented by incubating cells at 37 degrees C with human serum diluted 1 to 3 in the presence of a high concentration of rabbit IgG. This also facilitated distinction of sera with weak anti-PMN activity from normal sera. On the other hand, nonspecific staining remained on a fraction (10-25%) of mononuclear leukocytes. Following first-time transfusion of 0.5 to 5 units of whole blood or red cell concentrate, 4 of 27 patients (15%) developed anti-leukocyte antibodies. Anti-leukocyte antibodies were detected in 51 percent of 47 patients with reported febrile transfusion reactions; the IgG antibodies bound to PMNs in 38 percent of these 47 patients. Since only about one in three patients with febrile transfusion reactions had detectable IgG anti-PMN antibodies, fever may be caused by lysis of leukocytes other than PMNs.

Abstract
This report presents the major findings of the Nepal Blindness Survey, the first nationwide epidemiological survey of blindness, which was conducted in 1979-80. The survey was designed to gather data that could be used to estimate the prevalence and causes of blindness in the country. Ancillary studies were conducted to obtain information on socioeconomic correlates and other risk factors of blinding conditions and patterns of health care utilization.The nationwide blindness prevalence rate is 0.84%. Cataract is the leading cause of blindness, accounting for over 80% of all avoidable blindness. Trachoma is the most prevalent blinding condition, affecting 6.5% of the population. Very few cases of childhood blindness were detected.The implications of the survey findings for programme planning, health manpower development, and health education are discussed.

Abstract
The relationship between cataract prevalence, altitude, and sunlight hours was investigated in a large national probability sample survey of 105 sites in the Himalayan kingdom of Nepal, December 1980 through April 1981. Cataract of senile or unknown etiology was diagnosed by ophthalmologists in 873 of 30,565 full-time life-long residents of survey sites. Simultaneously, the altitude of sites was measured using a standard mountain altimeter. Seasonally adjusted average daily duration of sunlight exposure for each site was calculated by a method which took into account latitude and obstructions along the skyline. Age- and sex-standardized cataract prevalence was 2.7 times higher in sites at an altitude of 185 meters or less than in sites over 1000 meters. Cataract prevalence was negatively correlated with altitude (r = -0.533, p less than 0.0001). However, a positive correlation between cataract prevalence and sunlight was observed (r = 0.563, p less than 0.0001). Sites with an average of 12 hours of sunlight exposure had 3.8 times as much cataract as sites with an average of only seven hours of exposure. Sunlight was blocked from reaching certain high altitude sites by tall neighboring mountains.

Abstract
A technique that permits removal of viable retinal pigment epithelial (RPE) explants of determined size from Bruch's membrane, and the transfer of such explants with maintained apico-basal polarity to cell culture dishes is presented. The RPE is a polarized tissue where the apical surface is involved in the interchange of material between the choroid and sensory retina and in phagocytosis of visual receptor outer segments. The maintenance of this polarity is of importance in studies aimed at elucidating these functions on pure RPE explants in early primary culture. No previous work has presented a method that permits this maintenance. The possibility of standardizing the size of these explants should facilitate quantitative studies on phagocytosis and uptake of markers and labelled compounds. The described dissection procedure is also currently used to separate the RPE as a pure cell population from surgically removed chorio-retinal biopsies for cell culture purpose.

Abstract
Explants from the retinal pigment epithelium and the underlying choroid and sclera were dissected from human eyes and transferred to culture wells. The mechanical trauma caused by the dissection and removal of the explants, and the changes in biological milieu caused by transfer of the tissue to an in vitro system causes injury, necrosis and detachment of cells from Bruch's membrane. In the retinal pigment epithelium, cells adjacent to damaged, spherical and detaching cells and smaller cell free zones from rosettes. At the periphery of big defects, the cells spread out to cover the denuded areas of Bruch's membrane. The present work has shown that cell injury in the human retinal pigment epithelium is followed by reactive cellular changes in vitro. The result of these reactive changes are increased variation in cellular form and magnitude and in pigment concentration per unit area.

Fresh and undamaged cornea had unchanged endothelial cell density for four weeks in culture, while eyes removed at autopsy suffered a cell loss. Acceptable cell density was found in eyes removed within eight hours, and this was confirmed by the results of 55 penetrating grafts using cultured autopsy material. Storage in culture for more than one week seemed to influence the results unfavourably. Immune reactions were not seen.

Abstract
Seveteen children under the age of ten years with unilateral traumatic aphakia, who had been fitted with contact lenses, were reviewed by an ophthalmologist and an orthoptist, on average three years after the injury. Thirteen children were still using their lenses. Of the seventeen, none were deeply amblyopic. Only one had orthophoria. Twelve of the seventeen had heterotropia, which in most cases was moderate. Six of the children achieved stereopsis in the synoptophore, only four by the Titmus sterotest, all of these were six years old or more at the time of the injury, and had had lenses fitted within the first six months of the injury. All the patients, as well as their parents, were motivated for lens-wearing, and the lens played an important part in the treatment of amblyopia. It is concluded that the sooner the contact lens is supplied, the better are the changes of obtaining binocular function. Beginning with a soft lens a few weeks after achieving clear pupil is recommended.
