Abstract
Purified blood monocytes from patients with rheumatoid arthritis (RA) were significantly less capable of presenting purified protein derivative of tuberculin (PPD) to autologous lymphocytes than monocytes from patients with osteoarthritis, degenerative spine diseases, or healthy controls. Since lymphocytes from RA patients exhibited a normal response to soluble PPD or concanavalin A, the lowered T-cell reactivity had to be attributed to a diminished antigen-presenting capacity of monocytes. Several reasons may be responsible for this altered monocyte function in rheumatoid arthritis: a shift of monocytes to subpopulations expressing less Ia-like antigens, an inherent monocyte disorder, or a "preactivation" of monocytes associated with a reduced antigen-presenting capacity.

Abstract
We microdissected a Y chromosomal lampbrush loop pair from primary spermatocyte nuclei of Drosophila hydei and cloned the DNA directly at the microscale. Four of the 12 recombinant DNA clones recovered display in situ hybridization to mitotic metaphase Y chromosomes, preferentially in the chromosomal region identified as the origin of the lampbrush loop pair. All clones, however, also hybridize to autosomal and X chromosomal loci in polytene chromosomes. Y chromosomal DNA sequences of D. hydei again prove to be members of different families of repeated sequences distributed throughout the genome. These microcloning experiments, which were carried out under very unfavourable experimental conditions (low DNA content of the lampbrush loops in the presence of large amounts of RNA) prove that almost any chromosomal structure detected by light microscopy is directly accessible to molecular cloning experiments by micromethods.

Abstract
Six recombinant DNA clones are described, which are derived from the Y chromosome of Drosophila hydei. They reveal characteristic features of Y chromosomal DNA sequences. Three of the cloned inserts are Y-specific and are members of the same family of repeated sequences associated with the lampbrush loop-forming fertility gene "nooses" in the short arm of the Y chromosome. The other three cloned sequences are members of three different families of repeated sequences, but display a small amount of homology to one another and to the family of the nooses sequences. These three cloned sequences are found preferentially in the Y chromosome, but also in other chromosomal positions. The Y chromosomal copies are located in the short arm of the Y chromosome. The other copies are found in autosomal kinetochore-associated heterochromatin or, for one of the cloned sequences, in one band of the giant chromosome 4, in addition to the kinetochore heterochromatin.

Abstract
Between July 1973 and June 1981 systemic fungal infections were found in 27 of 270 autopsies of patients with hematologic malignancies: in 16 aspergillosis, in 6 candidiasis, in one aspergillosis and candidiasis, and in 4 mucormycosis. The frequency increased from 6% during the first 6 years to 25% during the last 2 years (p = 0.025). Fever despite antibiotics and new pulmonary infiltrates were the major symptoms. In only 6 of 16 patients did microbiological findings support the clinically suspected diagnosis. Systemic fungal infections were the principal cause of death in 12 patients. Because of the difficulty of establishing the diagnosis, empiric antimycotic therapy should be started promptly on clinical suspicion in patients with neutropenia and fever despite antibiotics.

Abstract
By recombinant DNA techniques, a Y chromosomal sequence of Drosophila hydei was isolated. This DNA sequence of 8.93-kilobase length is a member of a family of repetitive sequences located in the short arm of the Y chromosome. Tissue-specific transcripts complementary to the cloned sequence were found in testes RNA. In situ hybridization demonstrated that such transcripts are present in the lampbrush loop pair "nooses" in primary spermatocyte nuclei--a loop pair that is associated with the only fertility gene in the short arm of the Y chromosome.

Abstract
To investigate the histocompatibility requirements for the macrophage-T cell interaction in the secondary antibody response, splenic T cells from antigen (carrier)-primed F1 hybrid mice were restimulated in vitro with carrier-pulsed F1, parental or allogeneic macrophages. Surviving T cell were cocultured with hapten-primed F1 or parental "B cells" and restimulated with the appropriate hapten-carrier conjugate. The IgG antibody-forming cell response was then measured using a plaque assay. Mapping of the genetic restriction was performed by use of different strain combinations. T helper cells could be restimulated in the presence of macrophages only provided they shared the I-A subregion of the major histocompatibility complex with the F1 T cells frm F1 hybrids restimulated with parental or I-A-identical macrophages were shown to only cooperate with parental B cells of the same I-A haplotype as the macrophages used for restimulation. The defect was at the level of the macrophage, as addition of macrophages of the I-A haplotype used for the restimulation culture reconstituted ability of F1 helper cells to cooperate with the I-A-nonidentical B cells.

Abstract
TSH, T3 and T4 response to stimulation with thyrotropin releasing hormone (TRH) has been investigated in 24 young healthy adults after intravenous injection and in 25 young healthy adults upon oral application of 40 mg of TRH. After intravenous injection the TSH concentration raises from a mean of 1.6 to a mean maximum of 11.7 muU/ml. A statistically significant sex difference could not be found. T3 shows a statistically significant increase which is however too small to be of diagnostic value in an individual test. After oral stimulation with 40 mg of TRH, TSH rises to a slightly higher maximum of 13.2 muU/ml after 3 h. The T3 increase from 1.5 to 2.19 ng/ml is significant and considerably higher than after intravenous stimulation. The thyroxin increase is statistically significant. The present results compare well with previously published data for intravenous stimulation. The oral route of TRH application has not yet been widely used and the present series establishes the normal response in young healthy adults. Repetitive stimulation with three times 40 mg of TRH leads to a decrease in TSH stimulation which reaches 5.8 muU/ml 3 h after the third dose. This is in contrast to a comparable increase in plasma T3.

Abstract
The generation of T helper cells in vitro requires macrophages or macrophage-derived factors such as genetically related macrophage factor (GRF) or nonspecific macrophage factor (NMF). However, there is a basic difference of T helper cell induction when using particulate antigens. The present study demonstrates that this difference is based on the activation of two different T cell subsets. GRF activates short-lived 'T1' cells which amplify the induction of T2 cells, which are the helper cell precursors. Thus, the genetic restriction of T helper cell induction seen with soluble antigen or GRF lies on the level of macrophage or GRF interaction with T1 cells. NMF (or macrophages) and particulate antigens directly activate the helper cell precursor (T2) indicating no requirement for T1-T2 cooperation. The direct activation of the helper cell precursor with particulate antigens does not require histocompatible macrophages or NMF from histocompatible macrophages. The present results may explain some of the discrepancies reported in the literature concerning the genetic requirements and specificity of T cell activation.

Abstract
In a Zurich autopsy study comprising 7947 adults (over 20-year-olds), cor pulmonale was diagnosed in 8.9% (709 cases). In more than half of the cases the cor pulmonale was caused by lung diseases associated with chronic bronchitis and emphysema or with fibrosis of the lung. In 7 cases recurrent thromboembolism was the sole cause of cor pulmonale, whereas in 103 cases additional lung diseases were involved. 7 cases could be attributed to primary pulmonary hypertension. Cor pulmonale is, as a rule, the result of multiple lung conditions. The lesions of pulmonary vessels in cor pulmonale are produced either by parenchymatous lung changes (such as pneumoconiosis, sarcoidosis, etc.) or by pulmonary hypertension.

Abstract
Dry heat forms a specific burn toxin in mouse and human skin from a naturally occurring precursor by a polymerization process and not by producing breakdown products. Precursor and toxin are both macromolecular lipid-protein complexes with similar chemical composition and physical structure both occurring in mouse and human skin as well as in serum of burned patients. Specific toxicity resides only in the apoprotein of the polymeric toxic form which also has new specific artificially produced antigenic site or sites. This phenomenon makes it possible to jump the species from man to mouse, shown by the success of specific immunotherapy. Neutral apolar lipids of the coat are contributing in an unspecific but significant manner to the toxic effect. Bacteria are not involved in toxin production nor in toxin activity. The target systems of the toxin are the cell wall membranes of all parenchymal cells of paractically all organs. The toxin apparently causes severe damage of the membrane verified by an increased permeability for compounds which otherwise do not penetrate. This basic cell damage itself is able to kill the animal, depending on the ratio of intact to damaged cells. Sublethal doses of toxin, however, prepare the background upon which bacteremia in burn injuries leads to a lethal sepsis. Finally, the direct toxic action as well as the enhancement of the susceptibility for gram-negative organisms both leading to the lethal outcome can be counteracted by specific passive antitoxic immunotherapy.

Abstract
The RNAs of several avian tumor virus recombinants that had inherited their focus-forming ability from a sarcoma virus and their host range marker from a leukosis virus were investigated. Electrophoretic analyses showed that the cloned sarcoma virus recombinants contained only size class a RNA, although they had acquired a marker that resided on class b RNA in the leukosis virus parent. Class a RNA of different recombinant clones, derived from the same pair of parental viruses and selected for the same biological markers, differed slightly in electrophoretic mobility from each other and from the parental sarcoma virus. They were also found to have different fingerprints of RNase T1-resistant oligonucleotides. The average complexity of the 60-70S RNA prepared from Prague Rous sarcoma virus of subgroup B was estimated to be 3.5 x 10(6) daltons from the size of 20 RNase T1-resistant oligonucleotides, which represented 3.9% of the RNA and that of a recombinant to be 3.3 x 10(6) daltons from 23 oligonucleotides, which represented 4.7% of the RNA. This result suggests that the genome of wild-type and of recombinant RNA tumor viruses is polyploid. The sum of these observations led us to propose that recombination among avian tumor viruses occurred by crossing-over between homologous pieces of nucleic acid.
