| 4th seah cheng siang memorial lecture. primary gastrointestinal lymphoma in hong kong. | many primary gastrointestinal lymphomas (pgl) are treatable and carry a good prognosis, particularly of localized and of "low grade" malignancy. in general, the stomach is the most commonly involved site followed by the small and then large intestines. the incidence of gastric lymphoma may be on the rise, and the response of lymphoma arising from gastric mucosa associated lymphoid tissue (malt) to treatment of the co-existing helicobacter pylori infection has added a new dimension to the study o ... | 1994 | 7944264 |
| prevalence of metronidazole resistant helicobacter pylori strains among chinese peptic ulcer disease patients and normal controls in hong kong. | a study was conducted to evaluate the prevalence of metronidazole resistant helicobacter pylori strains among the chinese in hong kong. the efficacy of the triple therapy that contains metronidazole as one of the anti-microbial agents in eradication of the metronidazole susceptible and the metronidazole resistant strains was also assessed. | 1996 | 8707111 |
