    Notes: A fundamental point of discussion in poverty research is whether poverty is an absolute or a relative concept. If poverty is seen to be a situation of absolute deprivation, a poverty line will usually be defined to be independent of the general style of living in society. If poverty is considered to be a situation of relative deprivation, a poverty line will be defined in relation to the general style of living in society. The choice for one of these two approaches has important consequences for social policy, as absolute poverty may be reduced by economic growth, while relative poverty will only decrease when income inequality decreases. This paper suggests a poverty line definition that is not a priori meant to be either absolute or relative, but depends on the perception of poverty in society. If the poverty line is higher in countries with higher median income (as an indicator of “general style of living”) the poverty line is said to be relative; if the poverty line does not vary with median income, it is said to be absolute. The poverty line definition suggested appears to be a generalization of almost all well-known poverty line definitions. Poverty lines thus defined are estimated for eight European countries on the basis of a 1979 survey. The resulting lines appear to have an elasticity with respect to median income of 0.51, and hence can be said to be halfway on the scale between absolute and relative.

    Notes: Summary The distribution of type I, III, IV and V collagen in 35 gliomas and 20 meningiomas was studied by indirect immmunofluorescence staining. In addition, the presence of fibronectin (FN) and laminin (LN) is also reported. In gliomas expression of type IV collagen and LN was found in the vessel walls and associated with the endothelial glomerulus-like proliferations. FN and type V collagens were located in proliferating vessel walls in a pattern corresponding both to the basement membrane and the perivascular matrix around the vessels. In the extracellular matrix of grade III and IV gliomas occasional faint intercellular fluorescence was also observed with both FN and type V collagen. Type I and III collagens were localised in the vessel walls and in the perivascular connective sheet. Glioma cells did not express any of the antigens investigated. In meningiomas, type IV and V collagens, LN and FN were found in vessel walls, whorls formations and psammoma bodies. These stainings support the hypothesis of a vascular origin of these psammoma bodies which were only found in syncytial and transitional meningiomas. Both type I and III collagens were detected in the perivascular connective tissue. In general, meningioma cells and extracellular matrix did not express any of these molecules, except in transitional meningiomas where occasional fluorescence was observed in extracellular matrix with type V collagen and FN.

    Notes: Abstract The effects of misoprostol on human gastric antral mucosa were investigated in patients with established diagnoses of either gastric or duodenal ulcer. All patients had pretreatment biopsy. After starting treatment with misoprostol, antral biopsies were taken at four and eight weeks and were fixed in formaldehyde. Following fixation and routine tissue processing, the slides were stained with hematoxylin and eosin. A pathologist from the laboratory preparing the slides reviewed the slides and prepared surgical pathology reports. An identical slide of each biopsy was sent to pathologists at G.D. Searle and Company who were unaware of the diagnoses and who issued an independent descriptive report. Representative cases are presented for discussion. Misoprostol was administered at doses of 100 or 200 μg for four or eight weeks. No cellular or mucosal changes were observed. Both groups of pathologists were unable to recognize any dose-related or structural alterations. No special studies were performed on these tissues due to their fixation and sample size. Infiltration of the mucosa by chronic inflammatory cells with a variable number of granulocytes was the most common finding. There were a few cases of goblet cell metaplasia and mild hyperplasia both before and after treatment. By the application of histochemical and immunohistochemical staining methods it is hoped that the constituents in mucus and specialized cells can be identified.

    Notes: Summary Two F5 strains of tetraploid triticale (2n= 4x=28), obtained from 6x triticaleX2 rye progenies, were crossed with diploid and tetraploid rye, some durum and bread wheats, and various 8x and 6x triticale lines. Meiosis in the different hybrid combinations was studied. The results showed that the haploid complement of these triticales consists of seven chromosomes from rye and seven chromosomes from wheat. High frequencies of PMCs showing trivalents were observed in hybrids involving the reference genotypes of wheat and triticale. These findings proved that several chromosomes from the wheat component have chromosome segments coming from two parental wheat chromosomes. The origin of these heterogeneous chromosomes probably lies in homoeologous pairing occurring at meiosis in the 6x triticaleX2x rye hybrids from which 4x triticale lines were isolated. A comparison among different hybrids combinations indicated that the involvement of D-genome chromosomes in homoeologous pairing is quite limited. In contrast, meiotic patterns in 4x triticale X 2x rye hybrids showed a quite high pairing frequency between some R chromosomes and their A and B homoeologues.

    Notes: Abstract A method for the production of stable mouse-human cell hybrids containing a single human chromosome is described. As a first step in this method, a cloned selectable marker, the E. coli xanthine-guanine phosphoribosyltransferase (Ecogpt) gene, was transferred to human cells to generate cell lines each carrying Ecogpt integrated into a different site. Human chromosomes marked with Ecogpt were transferred further into mouse cells by microcell fusion. Monochromosomal hybrids, in which the human chromosome is maintained by selection, have been produced for chromosomes 2, 5, 16, and a rearranged chromosome involving a translocation between chromosomes 1 and 2. In addition to these monochromosomal hybrids, we have also obtained monochromosomal hybrids for human chromosomes 6, 12, and 17 by selection for the loss of marked chromosome from the microcell hybrids each containing two human chromosomes. Although the human chromosome present in these hybrids cannot be maintained by selection, 80–90% of cells retained the transferred chromosome on continuous growth for 15 days. Monochromosomal hybrids would provide biological materials to construct genetic maps of human chromosomes. In addition, chromosomes marked with dominant selectable markers can be transferred further to any cell line of interest in inter- or intra-species combination.
