Clinicopathological assessment of gastric biopsy samples of patients with Helicobacter pylori infection--metronidazole resistance and compliance problems in the United Arab Emirates.

The significance of Helicobacter pylori (HP) infection was assessed prospectively in forty-two patients with dyspepsia using histological, bacteriological and biopsy urease techniques. Thirty-eight patients (90.5%) were positive for HP infection and were treated with bismuth subcitrate (De Nol), tinidazole and doxycycline.

Glutathione and GSH-dependent enzymes in bronchoalveolar lavage fluid cells in response to ozone.

The purpose of this study was to determine if in vivo ozone exposure results in elevations in the levels of glutathione and glutathione-dependent enzymes in cells derived from bronchoalveolar lavage fluid (BALF). Our hypothesis was that, as part of a defense mechanism against oxygen toxicity, such cells would have increased levels of glutathione (GSH) in response to an oxidant stress. Female F344/N rats were exposed to 0.

Glutathione release by pulmonary alveolar macrophages in response to particles in vitro.

We studied whether cultured rat pulmonary alveolar macrophages (PAM) could release glutathione (GSH) in response to latex beads, quartz, and crocidolite asbestos. PAM were exposed for 2 h to 0-100 micrograms of particles per 1 x 10(6) cells. Both quartz and asbestos produced concentration-dependent increases (up to 8-10-fold) in the amount of GSH recovered in the medium and decreases in the cellular GSH levels.

Non-union of fractures of the mid-shaft of the clavicle. Treatment with a modified Hagie intramedullary pin and autogenous bone-grafting.

We reviewed a series of fifty patients who had a non-union of a fracture of the clavicle. Twenty-one patients (42 per cent) who had a symptomatic non-union of the middle of the shaft of the clavicle were treated with open reduction, internal fixation with a modified Hagie intramedullary pin, and autogenous bone-grafting, and those patients form the basis for the report. The average duration of follow-up was thirty-five months (range, five months to eleven years).
