    IgE antibody-mediated shock reaction caused by topical application of chlorhexidine (1986)

    Notes: A case of an anaphylactic shock following topical application of chlorhexidine preparation is reported. Specific skin-sensitizing antibodies against chlorhexidine were demonstrated in the serum from the patient by a passive transfer test. IgE antibodies against chlorhexidine were also detected by radioallergosorbent technique (RAST). Paper discs conjugated with chlorhexidine-HSA (human serum albumin) significantly bound the IgE antibodies. Furthermore, all of the sera from seven other patients with shock reactions following the topical application of chlorhexidine preparation also showed high RAST counts. Both chlorhexidine gluconate and chlorguanide which represents approximately half a molecule of chlorhexidine inhibited the reaction in a dose-dependent fashion. It is suggested that the shock reactions following topical application of chlorhexidine are mediated by IgE antibodies against chlorhexidine and that chlorhexidine and chlorguanide share the same antigenic determinant.

    Detection and characterization of acidic compartments (vacuoles) in Chlorella vulgaris 11h cells by 31P-in vivo NMR spectroscopy and cytochemical techniques (1987)

    Notes: Abstract Acidic inorganic phosphate (Pi) pool (pH around 6) was detected besides the cytoplasmic pool in intact cells of Chlorella vulgaris 11h by 31P-in vivo nuclear magnetic resonance (NMR) spectroscopy. It was characterized as acidic compartments (vacuoles) in combination with the cytochemical technique; staining the cells with neutral red and chloroquine which are known as basic reagents specifically accumulated in acidic compartments. Under various conditions, the results obtained with the cytochemical methods were well correlated with those obtained from in vivo NMR spectra; the vacuoles were well developed in the cells at the stationary growth phase where the acidic Pi signal was detected. In contrast, cells at the logarithmic phase in which no acidic Pi signal was detected contained only smaller vesicles that accumulated these basic reagents. No acidic compartment was detected by both cytochemical technique and 31P-NMR spectroscopy when the cells were treated with NH4OH. The vacuolar pH was lowered by the anaerobic treatment of the cells in the presence of glucose, while it was not affected by the external pH during the preincubation ranging from 3 to 10. Possible vacuolar functions in unicellular algae especially with respect to intracellular pH regulation are discussed.

    Characterization of the pyrenoid isolated from unicellular green algaChlamydomonas reinhardtii: Particulate form of RuBisCO protein (1988)

    Notes: Summary The pyrenoid is a protein complex in the chloroplast stroma of eukaryotic algae. After the treatment with mercury chloride, pyrenoids were isolated by sucrose density gradient centrifugation from cell-wall less mutant cells, CW-15, as well as wild type cells, C-9, of unicellular green algaChlamydomonas reinhardtii. Pyrenoids were characterized as a fraction whose protein/chlorophyll ratio was very high, and also examined by Nomarski differential interference microscopy. Most of the components consisted of 55 kDa and 16 kDa polypeptides (1∶1) which were immunologically identified as the large and small subunit of RuBisCO (ribulose-1,5-bisphosphate carboxylase/oxygenase) protein, respectively. Some minor polypeptides were also detected. Substantial amount of RuBisCO protein is present as a particulate form in the pyrenoid in addition to the soluble form in algal chloroplast stroma.
