[EXPERIMENTAL POSTTERIOIDEKTOMIC FATTY LIVER DISEASE IN RATS].

Unlabelled: The aim was to investigate the morphological features of the liver in animals at different periods of post-operative hypothyroidism to reproduce the experimental fatty liver disease.

Materials And Methods: thyroidectomy was performed 20 laboratory rats, females breed nonlinear, thyroid was mobilized without thyroid thyroidectomy to 10 individuals. The morphological pattern of the rat's liver was studied in terms of 4 and 8 weeks after surgery at the light optical level.

[Gastric and duodenal secretory and motor-evacuatory activity in patients with gastroesophageal reflux disease associated with different types of reflux].

Aim: To estimate esophageal and gastric pH values on an empty stomach and after stimulation of gastric secretion and gastric and duodenal motor-evacuatory activity in patients with gastroesophageal reflux disease (GERD) associated with pathological refluxes, such as gastroesophageal reflux (GER) and duodenogastroesophageal reflux (DGER).

Subjects And Methods: The observational cross-sectional study was conducted to investigate and compare the parameters of intraesophageal and intragastric pH metry and peripheral electrogastroenterography in 103 GERD patients with endoscopically positive distal reflux esophagitis in GER and DGER.

Results: The patients with GERD developed pathological esophageal refluxes (both GER and DGER) in various degrees of impaired gastric production, from anacidity to hyperacidity.
