    Notes: Chloroplast DNA variation in 96 Prunus avium L. cultivars was assessed and compared with the results of a previous study of cpDNA diversity in 23 wild populations of the species. The polymerase chain reaction-restriction fragment length polymorphism method was used in these studies. Approximately 9% of the chloroplast genome was analyzed, using five universal primer pairs and three restriction enzymes. Ten polymorphic fragments were common to both the wild and sweet cherry; eight polymorphic fragments were found only in the wild cherry. In the cultivars, all mutations were small (5-30 bp) indels. In the wild populations, a point mutation was also detected in addition to indels. The mutational combinations revealed three haplotypes in the cultivars, which are the main haplotypes in the wild cherry populations. Chloroplast DNA diversity in wild cherry is higher (16 haplotypes) than in sweet cherry cultivars (three haplotypes). The probable wild origin of the sweet cherry cultivars in the maternal line, on the basis of haplotypic similarity, was discussed.

    Notes: Granulomatous ulcerative colitis: a re-appraisal of the mucosal granuloma in the distinction of Crohn's disease from ulcerative colitis Aims: To determine whether the presence and location of giant cells or granulomas in relation to crypts distinguishes between ulcerative colitis and Crohn's disease. Methods and results: Twenty-nine large bowel mucosal biopsy specimens showing giant cells and/or granulomas in a background more typical of ulcerative colitis than Crohn's disease were collected between 1986 and 1996. Each was subject to detailed independent analysis by three histopathologists. Follow-up of the cases was by examination of all previous and subsequent gastrointestinal surgical or biopsy material and by scrutiny of the clinical notes by a gastroenterologist. On the basis of the accumulated histological data 10 of these 29 cases were accorded the diagnosis of ulcerative colitis. In nine of these 10 cases the clinical diagnosis, where known, was in keeping with this and all nine contained only crypt-associated giant cells and/or granulomas. The tenth case contained a solitary free-standing granuloma and clinically the patient had perianal disease, suggesting that the true diagnosis was Crohn's disease. Conclusions: Isolated giant cells and well-defined epithelioid granulomas distant from crypts do not, as a rule, occur in ulcerative colitis, and hence their presence in a colonoscopic biopsy showing features of chronic inflammatory bowel disease is a strong pointer towards the diagnosis of Crohn's disease. Crypt-associated giant cells and granulomas can occur in ulcerative colitis and in themselves are unreliable features for the discrimination between Crohn's disease and ulcerative colitis.

    Notes: Summary Humic acid-type polymers (melanins) synthesized in culture media by the fungi Aspergillus glaucus, Eurotium echinulatum, Hendersonula toruloidea, Stachybotrys atra and Aspergillus sydowi were analysed for elemental composition, functional group content, infrared (IR) and electron spin resonance (ESR) properties. Results were discussed in comparison with range values referred for soil humic acids. The fungal polymers showed significant differences in carboxyl and nitrogen content and C/H atomic ratios, reflecting a different degree of condensation (aromaticity) among the various samples. IR analysis gave evidence of: (a) the predominant aromatic character of melanins from A. glaucus, E. echinulatum and H. toruloidea; (b) the high content of aliphatic and olefinic components of S. atra melanin; (c) the typical presence of amide bonds in the nitrogen-richest melanins from A. sydowi and H. toruloidea; and (d) the generally low amount of free carboxyl groups, which often appeared involved in hydrogen bonds. ESR spectra showed that all the melanins studied contained appreciable concentrations of organic free radicals of prevailing semiquinonic nature and of the same order of magnitude commonly measured in humic acids from soil and other sources. The free electron concentration was shown to be directly related to the C/H atomic ratio and to the degree of aromaticity shown by IR analysis. This indicated that the highest free radical content in the melanins from E. echinulatum and A. glaucus was associated with the highest presence of condensed aromatic structures. Humic acid-type polymers synthesized by soil fungi may, therefore, contribute to the total free radical content of soil humic substances and play important roles in all reactions involving free radicals in soils and related environments.

    Notes: Summary Mouse hepatitis virus 3 (MHV-3) is highly hepatotropic in sensitive mice. Temperature-sensitive mutants (ts mutants) induced by N-methyl-N′-nitrosoguanidine and 5-fluorouracil were isolated. Twelve mutants which were able to induce the formation of syncytia at 33°C but not at the restrictive temperature (39.5°C) were selected for detailed study. No viral RNA synthesis was detected after infection at the restrictive temperature with six of the mutants (RNA−) whereas six others were RNA+, although they displayed RNA synthesis which was generally reduced. No differences have been detected in the size of the genome or the viral-intracellular RNA species found in wild type virus or ts mutant infected cells at permissive temperature. The pattern of virus-induced proteins analyzed after immunoprecipitation by SDS-PAGE was similar in wild type virus and RNA+ mutant infected cells at 39.5°C. Complementation experiments between ts mutants enabled us to distinguish five groups. Three of the groups contained RNA− mutants and two of them RNA+. Plaques made by mutants in one group displayed characteristic features that distinguished them from the wild type.

    Description / Table of Contents: Résumé Un allotype lent de l'albumine a été trouvé chez un donneur de sang. L'étude familiale confirme la liaison du locus de l'albumine et du système Gc. Parmi les 16 sujets porteurs du trait en simple dose, aucune manifestation pathologique ne semble associée. L'un des individus porte l'allèle lent en double dose, ce qui serait le premier cas d'une telle variété cathodique de l'albumine.
    Abstract: Zusammenfassung Bei einem Blutspender wurde ein langsamer Allotyp des Albumins gefunden. Der Zusammenhang zwischen Albumin-Locus und Gc-System wurde durch Familien-studien bestätigt. Bei 16 Patienten, Träger dieses Faktors in einfacher Dosis, scheint keine Beziehung zu pathologischen Beziehungen zu bestehen. Eine der Personen besitzt das langsame Allel in doppelter Dosis, was der erste Fall einer solchen kathodischen Albumin-Varietät wäre.
    Notes: Summary A slow albumin allotype was found in a blood donor. The albumin locus-Gc system relationship is confirmed by family studies. There seems to be no association with pathological manifestations among the 16 subjects bearing this factor in simple dose. One of the individuals possesses the slow allele in double dose, a fact which would be the first case of such a cathodic albumin variety.
