    Notes: Abstract Convulsions induced by the combination of enoxacin, a new antimicrobial, and nonsteroidal anti-inflammatory drugs including nimesulide, ketoprofen, pranoprofen and loxoprofen sodium, were investigated in mice. The oral administration of nimesulide alone induced clonic convulsions at more than 300 mg/kg. The oral administration of ketoprofen, pranoprofen or loxoprofen sodium induced no convulsion up to 1000 mg/kg, 500 mg/kg and 600 mg/kg, respectively, and that of enoxacin induced no convulsion at more than 5000 mg/kg. The combination of nimesulide at 200 mg/kg and enoxacin at 400 mg/kg induced no convulsion. In contrast, the combination of enoxacin at 100 mg/kg and either ketoprofen at 125 mg/kg or pranoprofen at 500 mg/kg induced clonic convulsions, while that of enoxacin at 400 mg/kg and loxoprofen sodium at 600 mg/kg induced no convulsion. These results suggest that the combination of nimesulide and enoxacin may possibly induce few or less convulsions in the clinical setting.

    Notes: Abstract  To study the proliferation and differentiation of pituitary corticotrophs, we administered bromodeoxyuridine (BrdU) to pregnant rats at 15.5–21.5 days of gestation and to rat pups at 3, 7, and 28 days after birth. The pituitary sections of fetuses and pups were consecutively immunostained with anti-BrdU and anti-adrenocorticotropic hormone (ACTH) to detect proliferating cells and corticotrophs, respectively. The number of cells labeled with BrdU, ACTH, or both were counted. The diameters of their nuclei and the volume of the pituitary were measured. The BrdU-positive cells were around 76,000–96,000/mm3 during the period studied. The corticotrophs were first detected in the fetus at 15.5 days and they increased during the fetal and postnatal periods. The double-labeled cells were first detected in the 17.5-day fetus. They increased markedly at 19.5 days and comprised about one-quarter of the corticotrophs that increased in 24 h at this stage. These results indicate that: (1) at 15.5–18.5 days the corticotrophs were derived almost exclusively from undifferentiated cells; (2) during the later fetal and early postnatal periods, the proliferation of existing corticotrophs contributed, at least in part, to their increase; (3) About 1/20 of proliferating cells differentiated to corticotrophs when their increase was required.

    Notes: In the course of analyzing the partial amino acid sequences of Cry j I, a major allergen of Japanese cedar (Cryptomeria japonica) pollen, we found a peptide fragment which has a significant homology to some pectate lyase isozymes secreted by plant pathogenic bacteria. Therefore, we investigated whether Cry j I has pectate lyase activity. Cry j I reacted with polygalacturonic acid, resulting in the release of unsaturated uronide products. The optimum temperature and pH for the reaction were 60–70°C and pH 10. The enzymatic reaction had an absolute Ca2+ ion requirement. These characteristics were very compatible with the character of the pectate lyase isozymes reported previously. These results clearly show that Cry j I has pectate lyase activity.

    Notes: Background: Japanese cedar (Cryptmeria japonica: CJ) pollinosis is one of the most important allergic diseases in Japan. Recently, the second major allergen (Cry j II) was isolated from CJ pollen. There have been no prevalence studies of sensitivity to Cry j I and Cry j II among a large number of patients with pollinosis.Objective: This study was conducted to evaluate the prevalence of sensitivity to Cry j I and Cry j II. We measured specific IgE antibodies to these allergens in the sera of 145 patients. Furthermore, comparison of the sensitivity to Cry j I and Cry j II was examined by the hisiamine release assay.Methods: Specific IgE antibodies to Cry j I and Cry j II were assayed by a fluorometric ELISA. Allergen-specific histamine release was measured by a radioimmunoassay kit,Results: More than 90% of 145 patients had specific IgE antibodies to both allergens. the remainder had specific IgE to either one or the other. There were seasonal changes in the level of specific IgE. The changes in the levels of anti-Cry j II IgE antibodies were parallel to those of anti-Cry j I IgE. The histamine release assay with leucocytes from the patients demonstrated that the allergenic potency of the two allergens is almost the same.Conclusion: Cry j II is an as important a major allergen as Cry j I.

    Notes: Background Japanese cedar (Cryptomeria japonica; CJ) pollinosis has been reported to occur naturally in Japanese monkeys (Macaca fuscata) as well as in humans. Most human patients and monkeys with pollinosis have specific IgE for Cry j 2, a major allergen of CJ pollen.Objective The main purpose of this study was to identify IgE B cell epitopes of Cry j 2 using a synthetic peptide in humans, monkeys and mice.Methods We synthesized 38 overlapping peptides that span the entire length of Cry j 2. We examined the B cell epitopes of Cry j 2 that are recognized by IgE in the sera of human patients and monkeys with pollinosis and immunized mice using synthetic peptides of Cry j 2. We also examined the reaction of Cry j 2-specific mouse monoclonal IgG antibodies to the peptides. Furthermore, we conducted a histamine release assay with leucocytes from a pollinosis patient using human serum albumin (HSA) conjugated with the peptides as a B cell epitope.Results We found that 16 of the 20 pollinosis patients who had specific IgE to Cry j 2 also exhibited IgE reaction with some Cry j 2 peptides. Of these 16 patients, 10 exhibited IgE reaction with Cry j 2 peptide no. 13 (121GQCKWVNGREICNDRDRPTA140). Five of the seven monkeys with CJ pollinosis exhibited a reaction with peptide no. 13. Furthermore, IgE in mice immunized with Cry j 2 and two mouse monoclonal IgG antibodies reacted with peptide no. 13. Peptide no. 13-conjugated HSA showed the release of histamine from basophils. Furthermore, to determine the minimum epitope in peptide no. 13, we conducted an enzyme-linked immunosorbent assay inhibition test. The core of the epitope in humans, monkeys and mice was 124KWVNGREI131.Conclusion We found that 124KWVNGREI131 is an important B cell epitope recognized by IgE in humans, monkeys and mice.

    Notes: To evaluate the efficacy and safety of two 1-week low-dose triple-therapy drug regimens involving antisecretory drugs for Helicobacter pylori infection, 99␣patients with H. pylori infection were treated with either lansoprazole or ranitidine used together with clarithromycin and metronidazole.〈section xml:id="abs1-2"〉〈title type="main"〉Methods:The drug combination and administration periods in the proton pump inhibitor group were lansoprazole 30 mg o.m., clarithromycin 200 mg b.d. and metronidazole 250 mg b.d., all given for 7 days (LCM group). The ranitidine group received ranitidine 150 mg b.d., clarithromycin 200 mg b.d. and metronidazole 250 mg b.d. also for 7 days (RCM group). The presence or absence of H. pylori was determined from gastric biopsy specimens taken from both the antrum and the body, by smear, culture and tissue section (Giemsa stain). Cure was defined as failure to find evidence of H. pylori infection 4 weeks after antimicrobial therapy had ended.〈section xml:id="abs1-3"〉〈title type="main"〉Results:The cure of H. pylori infection was 88% in the LCM group (44 of 50; 95% confidence interval (CI) = 79–97%) and 92% in the RCM group (45 of 49; 95% CI = 84–99%). The incidence of adverse events was 16% and 18% for the two groups, respectively.〈section xml:id="abs1-4"〉〈title type="main"〉Conclusions:No significant differences in cure rate and safety profiles were noted between the two regimens, suggesting that moderate acid inhibition using an H2-blocker is sufficient to achieve optimal H. pylori eradication.

    Notes: Cry j 1 and Cry j 2 are known to be the major allergens of Japanese cedar pollen. A comparative study was carried out on the immune responses to stimulation with Cry j 1 and Cry j 2 in 24 symptomatic patients and six nonallergic subjects. In T-cell proliferation assays, mean stimulation indexes (SI) were 10.6 for Cry j 1 and 11.7 for Cry j 2 stimulation, respectively, in the allergic patients. Two of the nonallergic subjects showed strong T-cell proliferation to both allergens, while the remainder did not. All the allergic subjects (17/17) showed high titers of anti-Cry j 1 IgE antibody at a mean value of 165 U/ml, whereas only 64% responded to Cry j 2 with low titers at a mean value of 26 U/ml. Nonallergic subjects did not respond with IgE production. Allergic subjects were further examined for their cytokine production profiles. All allergic subjects tested (16/16) produced high levels of interferon-gamma (IFN-γ) in response to Cry j 1 with a mean value of 918 pg/ml, while only five subjects showed significant elevation of IFN-γ production in response to Cry j 2 with a mean value of 679 pg/ml. The remainder produced small amounts of IFN-γ. Cry j 1 induced higher levels of interleukin (1L)-10 gene expression than did Cry j 2 stimulation, while both allergens induced IL-4 expression at a similar level. The IL-12 p35 gene was constitutively expressed, whereas the IL-12 p40 gene expression in Cry j 1-stimulated cells was elevated eightfold over that of nonstimulated cells. Increased expression of the IL-12 p40 gene was negligible in Cry j 2-stimulated cells. Thus, Cry j 1 stimulated mixed features of Th1 and Th2-like responses, while Cry j 2 played a minor role in inducing IgE production and cytokine (IFN-γ, IL-10, and IL-12) production, except for IL-2 production and strong T-cell proliferative activity. Therefore, it was concluded that Cry j 1 is the more important allergen, and that T-cell proliferation assays do not necessarily reflect the level of allergenicity.

    Notes: The immunodominant regions of the Japanese cedar pollen allergen Cry j 2 for T-cell immunity were determined with whole peripheral blood lymphocytes (PBL) derived from seven allergic patients and three nonallergic subjects. Cry j 2-stimulated T-cell proliferation was inhibited by anti-HLA-DR. but not by anti-HLA-DQ antibody, indicating that the responding T cells recognized the allergen peptides associated with HLA-DR molecules. It was found that seven regions of Cry j 2, i.e., regions corresponding to amino acid numbers 1–26, 70–84, 151–167. 187–203, 252–279, 283–314, and 345–362, were immunodominant for T-cell proliferation. Thus, Cry j 2 bears a limited number of immunodominant regions despite polymorphic features of HLA-DR in the immune system. This suggests the possibility of molecularly designing Cry j 2 antagonists that could downregulate allergic reactions to Japanese cedar pollen.

    Notes: The effects of recombinant human interleukin-1β (rhIL-1β) on alveolar bone resorptive activity in rats were examined. Continuous administration of rhIL-1β or phosphate-buffered saline (PBS) was given via osmotic pumps for 3, 7 and 14 days to rats with silk ligatures around second maxillary molars. Other animals without ligatures received insertion of pumps containing rhIL-lp or remained untreated. Sections were subject to three different stains:–hematoxylin and eosin (H-E) for histology, acid phosphatase (ACPase) activity for osteoclast detection, and immunohistochemistry using anti-rat monocyte/macrophage monoclonal antibody (ED 1). In addition, body weight, plasma calcium and phosphorus levels were monitored. The mean body weight of rats receiving rhIL-lp was significantly lower (P 〈 0.05 to P 〈 0.01) compared with untreated rats throughout the experimental period. On Day 7, plasma calcium and phosphorus levels were significantly lower in rats receiving rhIL-1β than in rats receiving PBS only (P 〈 0.05). Sections revealed a moderate inflammatory cell infiltrate reaching near the alveolar crest in both groups with ligatures on Day 3. Only rats receiving rhIL-lp exhibited enhancement of inflammatory cell invasion on Days 7 and 14. In rats receiving rhIL-lp with ligatures, numerous resorption lacunae containing ACPase-positive multinucleated giant cells (MNGCs), coinciding with ED1-positive cells, were located on the mesial side of the septum where extensive bone resorption had occurred throughout the experimental period. In animals receiving rhIL-β without ligatures, compared with untreated rats, increased ACPase-positive cells were observed on the mesial side of the septum on Day 3. In animals receiving PBS only, a few ACPase-positive cells were observed confined to the mesial regions where slight bone resorption occurred on Days 7 and 14. These results indicate that the administration of rhIL-1β accelerated alveolar bone destruction in ligature-induced periodontal tissue inflammation over a two-week period.

    Notes: Abstract Recent studies have demonstrated an important role of vascular cell adhesion molecule-1 (VCAM-1) in the pathogenesis of nephritis. In the present study, renal biopsy specimens from patients with proliferative and crescentic glomerulonephritis were subjected to immunoelectron microscopy using an anti-VCAM-1 monoclonal antibody. In control normal kidney tissue, VCAM-1 expression was restricted to the free surface of parietal epithelial cells. In diseased glomeruli, VCAM-1 was expressed on the free surface of parietal and visceral epithelial cells, on the luminal surface of capillary endothelial cells, on infiltrating monocyte/macrophage-like cells, on mesangial cells, and in the matrix of the expanded mesangium. There was also VCAM-1 expression on almost all cell types in the crescents, including macrophage-like cells, fibroblast-like cells, and epithelial cells. Some cells also showed VCAM-1 positivity in the rough endoplasmic reticulum and the perinuclear space. Both the glomerular capillary lumen and urinary spaces of Bowman's capsule contained positive reaction products, which were often associated with exocytosis by the surrounding cells. VCAM-1 was predominantly expressed on the basal and lateral surfaces of a few proximal tubules, but it could not be localized ultrastructurally. These findings suggest that production and secretion of VCAM-1 by both infiltrating monocyte/macrophages and resident glomerular cells may be related to the pathogenesis of proliferative and crescentic glomerulonephritis.
