[Retrospective analysis of the risk factors in patients with ischaemic heart disease hospitalized in the years 1983-1992].

Purpose: The aim of this study was to perform a retrospective analysis of selected risk factors and their variability in a 10 years period of observation in patients with ischemic heart disease (IHD).

Material And Methods: We reviewed 5219 questionares of patients hospitalized at internal wards of the Internal Medicine Institute of the Pomeranian Medical University in Szczecin. Among the participants 1709 were females with mean age 56.

[Strongyloidosis--a case report].

A case of Strongyloides stercoralis infection was described.

[Gastroesophageal reflux disease--diagnostic and therapeutic problems].

Endoscopy is the method commonly used in the diagnosis of GERD (Gastroesophageal Reflux Disease). Although it is not rare that despite of typical clinical symptoms of the disease, investigation doesn't show any changes. The aim of endoscopy is to monitor pathological changes occurring in GERD--severe inflammation of the esophagus, strictures, ulcers and Barrett's esophagus.

[Vitamin C and uric acid concentrations in plasma and gastric mucosa in patients regularly consuming vegetables, fruits and fruit juices].

Unlabelled: Vitamin C (Asc) as a reactive oxygen species scavenger inhibits detrimental oxidation reactions and counteracts formation of mutagenic compounds which damage DNA in the gastric and duodenal mucosa. It has been considered as an important factor in reducing risk of gastric carcinoma. However, the role of uric acid (UA) as an antioxidant factor and its influence on gastric mucosa has not been so well investigated.

[Malonyldialdehyde, uric acid and white cell count as markers of oxidative stress in acute myocardial infarction and acute coronary insufficiency].

Unlabelled: Free radicals, produced in large amounts during myocardial ischemia and reperfusion, take part in the degradation of cellular and subcellular membrane structures. The source of oxygen radicals in the ischemic myocardium are neutrophils recruited into the necrotic region, as well as metabolic transformation of hypoxantine and xantine to uric acid. Subsequent reactions generate lipid peroxides and cytotoxic and-products of oxidation, among which is malondialdehyde (MDA).
