    Notes: Summary An immunochemical micromethod was designed to estimate total IgG and IgG sub-classes of anti-insulin antibodies in immunized diabetic patients. Insulin, immobilized on a solid phase, was allowed to react with serum samples containing anti-insulin antibodies. Bound anti-insulin IgG interacted with mouse monoclonal antibodies specific for total IgG or for each IgG isotype. The fixation of mouse monoclonal antibody was subsequently detected using a horseradish peroxidase-conjugated rabbit anti-mouse IgG in the presence of a chromogenic substrate. The test was standardized by an immunocapture assay utilizing coated rabbit anti-human IgG and known concentrations of purified human myelomatous proteins of each sub-class. Results of anti-insulin IgG and anti-insulin IgG sub-classes assay could therefore be expressed in ng equivalent myelomatous proteins per ml of serum. Analysis of serum samples from 24 insulin-immunized diabetic patients revealed a quasi absence of IgG2 anti-insulin antibodies and an increase of the relative abundance of the other three anti-insulin IgG isotypes. In our series, anti-insulin IgG1 was predominant, followed by IgG3 (in 17/24 patients) or IgG4 (in 7/24). Insulin immunization was deduced to be of polyclonal nature, the isotype pattern of which is not representative of the relative proportion of IgG sub-classes in whole normal serum.

    Micropropagation of floribunda, ground cover and miniature roses (1989)
    Springer
    Plant cell, tissue and organ culture 19 (1989), S. 55-64

    Notes: Abstract Cultures were initiated from meristems (0.5 mm) of the rose cultivar Queen Elizabeth (floribunda) and from both shoot-tips and nodal explants (3–5 mm) of cultivars Sunburst Red, Toy Clown (miniatures) and Fiona (ground cover). Average proliferations of 5.0, 3.1, 1.3 and 2.5 shoots were obtained per culture cycle respectively on Murashige & Skoog (MS) medium with BA (1.0 mg l-1), NAA (0.1 mg l-1) and GA3 (0.1 mg l-1). With cv. Fiona, the proliferation rate was more than doubled by removal of the shoot apex. The rate of proliferation of cv. Queen Elizabeth was significantly increased by using long shoots (〉2 cm in length) and by re-culturing shoots to fresh medium every 3 weeks. In vitro rooting percentage with cv. Queen Elizabeth was enhanced by using long shoots (〉2 cm) and by dilution of MS medium to 1/4 strength. Transfer of shoots for direct rooting in compost was significantly improved by pre-culturing shoots for two weeks in vitro in media containing IAA, and by the use of sorbarods.

    The Relationship of pK a and Acute Skin Irritation in Man (1988)

    ISSN: 1573-904X

    Topics: Chemistry and Pharmacology
    Notes: Abstract The relationship between pK a and skin irritation in man is studied for a homologous series of benzoic acid derivatives, which permeate through human skin at comparable rates (15–88 µg/cm2/hr). Skin irritation and pK a are correlated for pK a ≤ 4. Laser Doppler velocimetric assessment of skin blood flow, color meter readings, erythema, edema, and the primary irritation index are all linearly correlated and related to pK a, erythema at 24 hr appears to be the most sensitive parameter to variation in pK a when pK a ≤ 4.
