Abstract
We have previously reported that IL-2-induced lymphokine-activated killer (LAK) cells have the capacity to lyse autologous and allogeneic monocytes. To understand the biologic significance of this interaction, we investigated the function of human monocytes against the opportunistic pathogen, Candida albicans, subsequent to a short exposure to autologous LAK cells. A highly sensitive radiolabel assay, which makes use of the incorporation of [3H]glucose into residual Candida after their incubation with monocytes, was developed to measure antifungal activity. Cultured monocytes, after 2 to 6 h exposure to LAK cells, were found to be substantially suppressed in their ability to control fungal growth. Moreover, monocytes cultured in the presence of granulocyte/macrophage (GM)-CSF or IL-3, were even more suppressed in function after a short incubation with LAK cells. The effect of GM-CSF was both time and dose dependent, with peak susceptibility induced after 4 days of culture with as little as 10 U/ml of the cytokine. These GM-CSF-cultured monocytes, however, were relatively resistant to inhibition by freshly isolated large granular lymphocytic NK cells. Therefore, IL-2 induces in large granular lymphocytic cells the capacity to inhibit monocyte function. In contrast to GM-CSF and IL-3, IFN-gamma was found to have a protective effect on monocytes, because monocytes cultured 4 days in IFN-gamma were not significantly inhibited by LAK cells. These results indicate that LAK cells may be involved in regulation of monocyte function and suggest that the state of differentiation induced by different cytokines may dictate the level of control of the monocytes by LAK cells.

Abstract
We recently mapped the gene for ataxia-telangiectasia group A (ATA) to chromosome 11q22-23 by linkage analysis, using the genetic markers THY1 and pYNB3.12 (D11S144). The most likely order was cent-AT-S144-THY1. The present paper describes further mapping of the AT locus by means of a panel of 10 markers that span approximately 60 cM in the 11q22-23 region centered around S144 and THY1. Location scores indicate that three contiguous subsegments within the [S144-THY1] segment, as well as three contiguous segments telomeric to THY1, are each unlikely to contain the AT locus, while the more centromeric [STMY-S144] segment is most likely to contain the AT locus. These data, together with recent refinements in the linkage and physical maps of 11q22-23, place the AT locus at 11q23.

Abstract
One hundred and fifteen new patients with Graves' hyperthyroidism were received thyroid suppression test after cessation of 6 month course of drug therapy. The results of follow up for another 12 months were that one of them had lost, 48 cases were in remission, and 66 cases had relapsed. The present study shows that thyroid suppression test, including the 4th, 6th and 24th hour suppression rates, is useful in predicting the outcome of drug therapy. The effect of 6th hour suppression rate is better than that of 24th and 4th hours, with 75.8% sensitivity, 75.0% specificity and 75.4% accuracy when 30% of thyroid suppression rate is as out-off point which is decided by ROC curve. It is suggested that 6 hour 30% suppression rate is better than the traditional 24 hour 50% suppression rate in the prediction of outcome of drug therapy.

Abstract
Two breakpoints within chromosome 11q23 were characterized with 29 DNA probes to establish a physical map of the region. This region is notable in that it contains at least 14 functional genes which are also syntenic in the mouse (chromosome 9). Chromosome 11q23 includes these markers: STMY, CLG, NCAM, DRD2, APOA1, APOC3, APOA4, CD3E, CD3D, CD3G, PBGD, THY1, ets-1, and cbl-2. The two breakpoints, herein called "X;11" and "4;11," defined a region of approximately 8 cM containing the APO and CD3 complexes as well as the polymorphic marker D11S29. DRD2 localized centromeric to the X;11 breakpoint despite evidence for close genetic linkage to D11S29, suggesting that DRD2 lies close to the X;11 breakpoint. THY1, PBGD, and cbl-2 localized telomeric to the 4;11 breakpoint and thus to the [D11S29--APO--CD3] grouping as well. The physical map helps to correlate the cytogenetic and linkage maps of this region. It also suggests that the human 11q23 syntenic grouping is inverted with respect to its murine counterpart. Based on this physical map and on our primary linkage map of the 11q23 region, we are able to confirm a preliminary localization of the gene for ataxia-telangiectasia group A (ATA) to a region centromeric to the interval defined by D11S144 (pYNB3.12) and THY1.

Abstract
One hundred and twelve new cases with Graves' disease were treated by tapazole for 6 months and followed-up for another 12 months in a prospective study. One hundred and eleven cases completed the whole course of study, and only one failed to be followed up. The results of the follow-up for 12 mon showed that the remission rate was 41.4% (46/111) and relapse rate was 58.6% (65/111). The present study indicated that the remission or relapse was related with serum levels of T3 before treatment, shrank goiter and disappearance of goiter bruit during the treatment as well as thyroid suppression rate, but not related to sex, age, period of illness before therapy or severity of the disease. It is suggested that a 6-mon antithyroid drug therapy instead of traditional long term therapy may be suitable for those patients who are with a reduced goiter and disappeared goiter bruit during the antithyroid therapy, and suppressible thyroid up-take by T3 and whose serum levels of T3 before treatment are not very high. So the patients may benefit from the short-term therapy. They are not only able to obtain a prolonged remission but also save time and money.

Abstract
We have constructed a genetic map of the human chromosomal region 11q22-23 by multipoint linkage analysis of 13 DNA polymorphisms that we have condensed into eight loci. An analysis for linkage disequilibrium between tightly linked probe/enzyme systems allows us to make specific recommendations for future DNA typing at these loci. The resulting sex-averaged multipoint map spans approximately 80 cM and differs considerably from previously reported genetic maps of this region. Our mathematically derived "most likely order" of the markers is compatible with physical mapping data using somatic cell hybrids. The known localizations of at least 14 functional genes and several disease loci to 11q22-23, including ataxia telangiectasia, make the mapping of this region especially relevant to studies of disease pathogenesis.
