    Notes: This study was designed to determine seasonal changes in cytokines, soluble CD23 and specific IgE in the serum of patients with seasonal allergic rhinitis, and the effect of immunotherapy on these seasonal changes. Fifty-four patients with seasonal allergic rhinitis caused by Japanese cedar pollens were divided into a medication group and an immunotherapy group. The patients of the medication group were treated with non-sedating antihistamines alone during the pollen season. The patients of the immunotherapy group had been treated for variable periods (mean, 5.0 ± 3.2 years) with immunotherapy using Japanese cedar pollen antigens. Serum samples were collected before and during the pollen season from each patient, to determine specific IgE, interleukin-4 (IL-4), interferon-γ (IFN-γ) and soluble CD23 levels in serum. A significant increase in specific IgE and IL-4 and a significant decrease in IFN-γ were observed during the pollen season in the medication group. In contrast, in the immunotherapy group, none of specific IgE, IL-4 and IFN-γ was significantly changed following natural exposure to pollens. However, these effects were not significant in patients undergoing immunotherapy for 3 or fewer years. Seasonal rates of increase in specific IgE and IL-4 differed significantly between good responders and poor responders to immunotherapy, but seasonal rates of decrease in IFN-γ did not. A seasonal rate of increase in soluble CD23 was significantly correlated with a seasonal rate of increase in specific IgE, in both the medication and the immunotherapy groups. The seasonal rate of increase in soluble CD23 was significantly smaller in the good responders than in the poor responders to immunotherapy. In conclusion, pollen immunotherapy reduces the seasonal increase in specific IgE, IL-4 and soluble CD23 in serum, and in addition switches the seasonal preferential activation of Th-2 cells to reciprocal activation of Th-1 cells with treatment over several years. It is likely that the mechanisms responsible for the clinically beneficial effects of immunotherapy principally involve the modulation of Th-2 rather than Th-1 cytokines.

    Notes: Salivary glands of autoimmune MRL/1 mice were examined ultrastructurally and by immunoelectron microscopy to further characterize the Sjögren's syndrome-like disease in these animals. Major salivary glands from 12 female and 7 male MRL/1, two female MRL/n, and one female BALB/c mice were examined by electron microscopy and the glands from 4 female MRL/1 mice were subjected to immunoelectron microscopy in order to detect Lyt-1 and Lyt-2 positive lymphoid cells. Mononuclear cell infiltrates were not seen in the salivary gland from the BALE mouse and occurred rarely in glands of MRL/n mice. However, in MRL/1 mice, numerous lymphoid cells were present and acinar cells displayed low cytoplasmic density, cytoplasmic vacuolization and cellular lysis. Lymphoid cells were predominantly Lyt-1 positive although some Lyt-2 positive cells were observed. These results suggest that the MRL/1 mouse represents a useful model for the study of the pathogenesis of Sjogren's syndrome in man.

    Notes: The specific IgE antibodies to moth (Bombyx mori) and midge (Chironomus yoshimatsui) were measured by the Pharmacia CAP system in 51 house-dust-mite-sensitive asthma patients. None of these patients had definite histories of exposure to these insects or apparent evidence of insect-induced asthma symptoms. The RAST-inhibition assay was performed to investigate cross-allergenicity between these two insects. Furthermore, IgE immunoblotting was done to study the IgE-binding components in moth and midge extracts. Thirty (59%) of these patients showed positive IgE antibodies to moth, while 25 (49%) showed positive IgE antibodies to midge. Those frequencies of positivity were similar to that for Japanese cedar pollen, which is well known to cause allergy. A significant correlation (r=0.863) was observed between IgE antibody liters of these two insects. The results from the RAST-inhibition assay indicated cross-allergenicity between these insects and also the existence of species-specific allergens. Fifteen IgE-binding components in moth extract were observed. The most frequent IgE-binding protein was the 79-kDa (84.2%), followed by the 72-kDa (78.9%), the 82-kDa (57.9%), and the 76-kDa (57.9%) proteins. Those were considered to be major allergens in moth. Twenty-four IgE-binding components in midge extract were observed. However, no IgE-binding protein to which over 50% of patient sera reacted was observed. These results suggest that these two insects may be considered to bear important allergens and that there is cross-allergenicity between these insects as well as species-specific allergens.

    Notes: : To examine gastric mucosal ulcerogenic responses to indomethacin and HCl/ethanol in adjuvant arthritic (AA) rats.〈section xml:id="abs1-2"〉〈title type="main"〉Methods and Results: Arthritis was induced in male Dark Agouti (DA) rats by injection of Freund's complete adjuvant (FCA) into the right hind paw. The gastric ulcerogenic response to indomethacin was markedly worsened in AA rats, depending on the degree of arthritic change. This aggravation of indomethacin-induced gastric lesions in AA rats was significantly prevented by NG-nitro-L-arginine methyl ester (L-NAME) and amino-guanidine as well as dexamethasone. In contrast, the mucosal ulcerogenic response to HCl/ethanol was inhibited in AA rats. The suppression of HCl/ethanol-induced gastric lesions in AA rats was reversed almost totally by L-NAME and aminoguanidine as well as dexamethasone and partly by indomethacin. The expression of inducible nitric oxide synthase (iNOS) mRNA was observed in the stomach of AA rats but not of normal rats. Moreover, the luminal releases of nitric oxide (NO) metabolites as well as prostaglandin (PG) E2 were significantly increased in AA rats.〈section xml:id="abs1-3"〉〈title type="main"〉Conclusions: The gastric mucosal ulcerogenic responses were modified in AA rats, in different manners depending on the irritants; an increase in response to indomethacin and a decrease in response to HCl/ethanol. These changes may both be accounted for by increased production of NO by iNOS, and the latter is also partly related to increased production of PGs.

    Plating fog generation in the forming of printed circuits by the additive method (1997)

    Notes: Abstract Plating fog is often observed when metallizing a latent pattern by electroless copper plating. Metallic elements in the nuclei of plating fog particles are analysed using electron probe microanalysis (EPMA). Silver and iron are invariably found in the particles. The iron is driven into the board during the liquid honing process and reduces silver ions in the photosensitive material to silver metal which causes plating fog. Plating fog also arises from reduced copper particles or generated hydrogen gas bubbles when they are trapped on the unpatterned region. Mechanical stirring accompanied by substrate oscillation is an effective method of avoiding plating fog.

    Notes: Summary Living and growing microbial cells were immobilized by entrapping in synthetic resin gels prepared from their prepolymers, and used in the production of various useful substances. The production of the desired metabolites and also both the activity and the stability of the catalytic systems were seriously affected by the physico-chemical properties of the prepolymers, and those of the resin gels subsequently formed, such as gel network, hydrophilicity-hydrophobicity balance and ionic nature, as well as by the type of bioreactors. Hydroxylation of steroids and production of antibiotics, polypeptides and other biologically active substances, and the effects of gell properties on them are discussed as examples.

    Notes: Abstract Bombyxin is a 5 kDa insulin-related peptide produced in four pairs of medial neurosecretory cells in the brain of the silkmothBombyx mori. We demonstrate here the presence of bombyxin mRNA in tissues other than brain: ganglia, epidermis, testis, ovary, fat body, silk gland, Malpighian tubule, midgut, and hindgut of theBombyx fifth instar larvae. Bombyxin mRNA was detected by Oligotex reverse transcription-polymerase chain reaction (RT-PCR), a rapid and simple procedure of reverse transcription-PCR, and in situ hybridization. The Oligotex RT-PCR method effectively eliminated the contaminating DNA in RNA samples and amplified bombyxin mRNA efficiently. In situ hybridization of theBombyx ovary clearly demonstrated the localization of the bombyxin mRNA in the ovariole. The present study is the first demonstration of expression of brain neurosecretory peptide in tissues other than the central nervous system in insects at RNA level.
