    Notizen: : The physicochemical, textural, and quality characteristics of Chinese-style meatball (20% fat) containing varying levels of bacterial cellulose (nata) were evaluated. Cooking losses of nata-containing Chinese-style meatballs were higher than those of control (containing no nata and 20% fat [C20]). Raw nata-added batter had higher water-holding capacity than control, but the pattern was reversed after cooking. N10 (10% nata) and C20 had the highest springiness scores. Textural hardness and shear-force value were significantly higher for C20, but both attributes for nata-added treatments decreased with increasing nata levels. Addition of 10% nata to Chinese-style meatballs produced products with acceptable textural and sensory qualities. Nata showed potential as a functional ingredient in Chinese-style emulsified meat products such as Chinese-style meatballs.

    Purification and Characterization of Escherichia coli Sulfite Reductase and its Application in Surimi Processing (2002)

    Notizen: : The NADPH-sulfite reductase from Escherichia coli was purified to electrophoretic homogeneity by ammonium sulfate fractionation, and DEAE Sephacel and Sephacryl S-300 HR chromatography. The recovery and molecular weight were 31.7% and 119000, while the optimal pH and temperature for the activity were 7.7 and 25°C, respectively. It was strongly inhibited by PCMB, KCN, Hg2+, Fe2+, Fe3+, Ca2+, Co2+, and Cu2+, moderately by NEM, PMSF, IAA, Cd2+, Zn2+, Mn2+, and Ba2+. Addition of purified reductase significantly increased the reactive SH and gel strength of surimi prepared from frozen mackerel. The data suggest the high potential of microbial NADPH-sulfite reductase in surimi processing using frozen fish or denatured muscle proteins as raw materials. Keywords: Escherichia coli, sulfite reductase, mackerel, purification, characterization

    Occurrence of peptic ulcer disease in connective tissue disease patients associated with xerostomia (2003)

    Notizen: Background : Saliva plays a role in mucosal protection and ulcer healing.Aim : To study whether decreased salivary production leads to peptic ulcer disease in connective tissue disease patients associated with xerostomia.Patients and methods : Two hundred and two connective tissue disease patients (90 with xerostomia and 112 without xerostomia) were enrolled. Their demographic data and use of medications were recorded. Peptic ulcer disease was confirmed by endoscopy. The stimulated salivary output and secretory epidermal growth factor level were measured.Results : Compared with non-xerostomic counterparts, xerostomic patients manifested a higher occurrence of peptic ulcer disease (31% vs. 12%, P = 0.001), lower stimulated salivary output (9.3 ± 4.1 vs. 22.9 ± 5.9 mL/15 min, P 〈 0.001) and lower stimulated salivary epidermal growth factor output (1.40 ± 0.77 vs. 3.00 ± 0.96 ng/min, P 〈 0.001). Multivariate analysis disclosed that an older age (≥ 60 years) (odds ratio, 4.71; P 〈 0.001), xerostomia with stimulated salivary output of ≤1 mL/min (odds ratio, 7.54; P = 0.014) and the use of non-steroidal anti-inflammatory drugs (odds ratio, 5.76; P = 0.031) were the risk factors leading to peptic ulcer disease. In addition, xerostomic connective tissue disease patients receiving non-steroidal anti-inflammatory drugs manifested an extremely high risk of development of peptic ulcer disease (odds ratio, 19.78; P 〈 0.001).Conclusions : Ageing, the use of non-steroidal anti-inflammatory drugs and poor salivary function are potential risk factors for the development of peptic ulcer disease in patients with connective tissue disease. If these xerostomic subjects consume non-steroidal anti-inflammatory drugs, they will encounter an extremely high peptic ulcer disease risk.

    The potential risk factors leading to peptic ulcer formation in autoimmune disease patients receiving corticosteroid treatment (2002)

    Notizen: Aim : To study the potential risk factors leading to peptic ulcer disease among autoimmune disease patients on corticosteroid treatment.Methods : One hundred and thirty-eight corticosteroid-treated autoimmune disease patients were enrolled; their demographic data were recorded and laboratory data were measured. Endoscopy was performed to assess the occurrence of peptic ulcer disease. Helicobacter pylori infection was diagnosed on the basis of rapid urease test and histological examination.Results : Twenty-eight (20%) of 138 autoimmune disease patients had peptic ulcer disease, including 17 with gastric ulcer, eight with duodenal ulcer and three with gastric ulcer plus duodenal ulcer. Eighty five (62%) had used non-steroidal anti-inflammatory drugs and 46 (33%) had H. pylori infection. The majority of peptic ulcer disease subjects showed the following characteristics: age ≥ 60 years; male; smokers; non-steroidal anti-inflammatory drug users, particularly the non-specific cyclo-oxygenase inhibitors; presence of hyperpepsinogenaemia I; low H. pylori colonization (P 〈 0.05). Multivariate analysis revealed that an age ≥ 60 years [odds ratio (OR), 6.80; P = 0.001], smoking (OR, 7.94; P = 0.004) and the use of non-specific cyclo-oxygenase inhibitors (OR, 4.71; P = 0.030) were the predominant risk factors for the development of peptic ulcer disease among these patients, whereas H. pylori infection showed a protective role (OR, 0.20; P = 0.022).Conclusions : Old age, smoking and the use of non-specific cyclo-oxygenase inhibitors are risk factors for peptic ulcer disease in autoimmune disease patients on corticosteroid treatment. H. pylori infection appears to protect against peptic ulcer disease in these patients.
