    Notes: Abstract  Azorhizobium caulinodans strongly colonized the rhizosphere of rice plants after incorporation of Sesbania rostrata in a field trial throughout the growing season and during the fallow period until 19 weeks after incorporation of S. rostrata. A. caulinodans became well established in the rhizosphere (7.17 log cfu g–1 dry rice root) and colonized subsequent S. rostrata test plants. Three traditional and three improved high-yielding rice varieties were inoculated with A. caulinodans under gnotobiotic conditions. In none of the combinations did acetylene reduction activity significantly increase. Ethylene production on colonized rice roots only started after the growth medium had been supplemented with an extra C source (0.1 to 0.25% Na-lactate). This indicates that the bacterial nitrogenase activity is limited by energy supply. Four possible inoculant-carriers (peat, coir dust, bagasse, rice straw) were compared for long-term survival of the bacterial strain. Independent of the storage temperature (26  °C or 4  °C), the survival of A. caulinodans in peat and coir dust was very high during a 12-month period (〉8 log cfu g–1 dry carrier), whereas the bagasse and rice straw carriers showed a serious decline from 3 months onwards.

    Tissue expression of CA-125 and carcinoembryonic antigen in ovarian carcinoma in relation to nuclear DNA content, histologic grade, and patient survival (1992)

    Notes: In a prospective study the immunohistochemically detectable tissue expression of the antigens CA-125 and CEA in 112 epithelial ovarian carcinomas and 23 borderline tumors was related to histologic features of the tumor and to patient survival. The CA-125 antigen was expressed mainly in non-mucinous tumors, with no evident association between histologic grade and immunoreactivity. CEA was expressed in mucinous tumors regardless of tumor grade. Flow cytometric DNA analysis was performed on fresh frozen tissue in a subgroup of 60 cases. There was no association between DNA ploidy or S-phase fraction and the CA-125 or CEA antigen expression. Tumor stage, size of residual tumor masses after surgery and DNA ploidy had independent associations with patient survival in multivariate log-rank analysis of prognostic factors. However, there was no association between the CA-125 or CEA antigen expression and patient survival. Thus, in ovarian carcinoma the expression of the CA-125 and CEA antigens seems to be independent of the inherent malignant potential of the tumor epithelium, while DNA analysis provides valuable prognostic information.

    CHEMICAL INHIBITION OF CROP GERMINATION BY WEED SEEDS AND THE NATURE OF INHIBITION BY ABUTILON THEOPHRASTI (1964)

    Notes: Summary. Aqueous extracts of the ground seeds of thirteen weed species were assayed for their ability to inhibit the germination on filler paper of eight crop species. All of the extracts delayed germination of at least some of the crop species. Germination of some crop species was delayed when the crop seeds were surrounded by weed seeds on filter paper, The seeds of Abutilon theophrasti were inhibitory to tomato (Lycopersicum esculentum) germinated in sterile and non-sterile soil in the laboratory. The inhibition of germination was apparent under conditions which excluded light, water and minerals as factors in the competition. Chemical studies indicated that the inhibition by Abutilon seeds was due to free amino acids emanating from the seeds.

    Atopy patch test with house dust mite allergen – an IgE-mediated reaction? (2004)
    Oxford, UK : Munksgaard International Publishers
    Allergy 59 (2004), S. 0 
    Details

    Topics: Medicine
    Notes: Background:  The eczema reaction in the atopy patch test (APT) is proposed to be immunoglobulin (Ig)E mediated, but can take place also in individuals lacking allergen-specific IgE in serum. The purpose of this study was to evaluate the importance of allergen-specific serum IgE for the APT reaction.Methods:  Ten patients with reproducible positive APT to extract of Dermatophagoides pteronyssinus, five patients with (group A) and five patients without (group B) detectable serum-IgE to D. pteronyssinus, were tested with extract of D. pteronyssinus on normal skin for 6, 24, 48 and 72 h. Skin biopsies were taken and analysed for cell infiltrates, eosinophils (EG2), IgE, FcɛRI, CD1a, CD4, CD8 and metalloproteinase 9 (MMP9).Results:  The number of IgE+, CD4+, EG2+ and MMP9+ cells increased with time in group A. FcɛRI+ cells and CD8+ cells increased with time in both groups. A correlation was found between the levels of D. pteronyssinus-specific serum-IgE and the score of dermal cell infiltrates at 72 h. The three patients with the highest values of allergen-specific IgE also had the highest expression of EG2+ cells and the highest APT scores.Conclusions:  Our study strengthens the hypothesis that the IgE molecule has a key role, at least as an amplifier, in the APT reaction.

    Effectiveness of occlusive bedding in the treatment of atopic dermatitis – a placebo-controlled trial of 12 months' duration (2001)

    Notes: Background: Several studies on avoidance of house-dust-mite (HDM) and cat allergens have been carried out, most of them in asthmatic patients and only a few in patients with atopic dermatitis (AD). No study so far has focused on which subgroup of AD patients benefits from avoidance measures. Methods: Forty adult patients with AD completed the 12-month avoidance study. They were divided into an active treatment (n=22) and a placebo (n=18) group. Active treatment comprised use of polyurethane-coated cotton encasings for bedding, and placebo use of cotton covers. Patients came for regular checkups during the 12-month period, when eczema severity was assessed and blood samples were analyzed for total IgE, HDM- and cat-specific IgE and soluble CD30 (sCD30) in serum. Dust samples were collected from mattresses before treatment and after 3, 6, and 12 months, and analyzed for content of HDM and cat allergen. Results: Eczema severity decreased significantly in both groups (P〈0.001), with a more pronounced decrease in patients with active covers. The HDM exposure decreased significantly in the active treatment group (P〈0.001), and the levels of HDM-specific IgE were reduced (P〈0.05). Exposure to cat allergens was unchanged in the active treatment group but decreased, albeit not significantly (P=0.19), in the placebo group. sCD30 levels were significantly reduced in both groups (P〈0.001). Patients not sensitized to HDM allergens benefited from the bedcovers as much as sensitized patients. Conclusions: Occlusive bedding significantly reduced HDM exposure in bed (P〈0.001) and eczema severity, and sCD30 levels decreased significantly (P〈0.001). Patients not sensitized to HDM and not exposed to HDM allergens benefited equally from use of the bedcovers, a result which could be due to a reduction of other important allergens, superantigens, or irritants in bed. We therefore recommend the use of bedcovers as part of treatment for AD.

    Sensitization to allergens of house-dust mite in adults with atopic dermatitis in a cold temperate region (1999)
    Copenhagen : Munksgaard International Publishers
    Allergy 54 (1999), S. 0 
    Details

    Topics: Medicine
    Notes: Background: An IgE-mediated contact reaction to airborne allergens has been suggested as one important pathogenetic mechanism in atopic dermatitis (AD). The house-dust mite (HDM) might be a common allergen involved. In Scandinavia, sensitization to HDM has been rare, probably because of the cold, dry climate. However, recent studies indicate high levels of domestic mites and HDM allergen in 15–20% of homes in central and northern Sweden. Methods: To evaluate the importance of the HDM in patients with AD in the Stockholm region, we screened 81 adult Stockholm residents with AD, for the prevalence and degree of sensitization to the HDM, according to specific IgE (RAST), skin prick test (SPT), and atopy patch test (APT). We also assessed the HDM exposure in their homes and correlated the results with clinical history, severity of the dermatitis, and type of residence during childhood and today. Results: The sensitization rate to HDM was high (56% according to RAST, 24% according to SPT, and 47% according to APT), and 20% of the patients were exposed to HDM allergens in their beds. Mite exposure seemed to aggravate the dermatitis in highly sensitized patients. Conclusions: The results indicate that we have to take the HDM into account when discussing aggravating factors in adult patients with AD in the Stockholm region.
