Recently, the results of many experimental investigations have shown that melatonin possesses gastroprotective properties. On the other hand its role in pathogenesis of upper digestive tract diseases in man still remains unclear. The aim of the study was to investigate nocturnal secretion of melatonin in patients with functional and organic diseases of the(More)
AIM OF THE STUDY We evaluated the effect of melatonin supplementation on the nutritional status of postmenopausal women. MATERIAL AND METHODS The study included 56 women (51-65 years) and 25 healthy women (27-36 years).

Estrogen deficiency is considered to be the main cause of increased appetite and increased weight in postmenopausal women. In this period, reduced secretion of melatonin (MEL) was also observed. The aim of the study was to evaluate the secretion of melatonin, 17-β estradiol and follicle-stimulating hormone (FSH) in relation to body mass index (BMI) in pre-(More)
Helicobacter pylori (H. pylori) infection plays an important role in gastric carcinogenesis. This bacterium may induce cancer transformation and change the susceptibility of gastric mucosa cells to various exogenous dietary irritants.

Helicobacter pylori colonization of gastric mucosa causes pain of unknown etiology in about 15-20% of infected subjects. The aim of the present work was to determine the level of expression of enzymes involved in the synthesis of melatonin in gastric mucosa of asymptomatic and symptomatic H. pylori infected patients. To diagnose H. pylori infection,(More)
