The analysis includes 58 patients with an ulcer in the duodenum, 40 patients with an ulcer in the stomach, and 13 persons making up the control group. In all patients submitted to the ratio-isotopic estimation of the duodeno-gastric reflux as well as to the chromatographic determination of the concentration of bile acids and lysolecithin in the gastric juice, an almost identically frequent occurrence of the reflux of the duodeno gastric contents into the ulcer of the stomach and of the duodenum was confirmed. It was shown that half of the ulcers of the stomach originate without the participation of the duodeno gastric reflux. It was also established that the average total concentrations of bile acids and lysolecithin are very high in the gastric juice, and in some even statistically significant cases, in the ulcer of the stomach in comparison with the remaining analysed groups of patients.

To estimate the correlation between frequency of Helicobacter pylori (H. pylori) infection and intensity of duodeno-gastric reflux it was analysed 61 species with ulcer gastric. Bacterial infection was diagnosed by the breath test with {sup 14}C-labelled urea, whereas presence and intensity of the reflux was found with dynamic scintigraphy with {sup 99}Tm MBrIDA support. The H. pylori infection was present at 42 (68.9%) patients. The presence of throwing back the duodenal liquid was found at 32 (52.5%) diagnosed patients. At 19 (31.2%) of them the reflux has intensity of 1%, at 11 (18%)-2{sup o} and 2 (3.3%)-3{sup o}.The investigations which were carried out, showed that at patients with ulcer gastric disease, duodeno-gastric reflux is an agent which slows down H. pylori infection, however it is easily seen not earlier than at 2{sup o} of its intensity.

Control test including gastroscopy with biopsy of the mucous membranes as well as the radioisotopic evaluation of the duodenogastric reflux were conducted on 101 patients after non-resectional operations of the stomach carried out because of an ulcerous disease. The significantly frequent occurrence was confirmed of atrophic gastritis alterations and dysplasia in cases of prevailing reflux. It was proved that the gastroenterostomy as well as the vagotomy with pyloroplasty were operations particularly leading to the rejection into the stomach of the duodenal content. The high selective vagotomy proved to be the operation least including to reflux. The observations made were fully reflected in the histological picture of the operated stomach.

We assessed by means of Tc-99m-HEPIDA cholescintigraphy the gastroduodenal reflux in 28 children with endoscopic signs of gastric biliary reflux. Those children were selected from a group of 190 children who underwent endoscopy because of abdominal pain disorders. We found the positive cholescintigraphic test in 67% of children. In 6 control tests after 4-months treatment with cisapride we found the withdrawal of cholescintigraphic signs, which corresponded with the improvement of clinical signs. The authors consider the cholescintigraphic examination useful in evaluation of biliary reflux in children, for the sake of more non-invasive character in comparison to endoscopy and X-ray contrast imaging after catheterizing of duodenum.

Choroba refluksowa przełyku a astma oskrzelowa
Directory of Open Access Journals (Sweden)

Full Text Available Astma oskrzelowa i choroba refluksowa przełyku są często współwystępującymi jednostkami chorobowymi. Uważa się, że refluks stanowi potencjalny czynnik wywołujący lub zaostrzający astmę. Hipoteza ta opiera się zarówno na przesłankach patofizjologicznych, jak i badaniach klinicznych. W badaniach eksperymentalnych wykazano, że zakwaszanie dolnej części przełyku powoduje wzmożoną reaktywność oskrzeli. Powstało kilka teorii wyjaśniających to zjawisko, do najistotniejszych należą teoria nerwowa, zapalna i mikroaspiracji. Wykazano również, że nieswoiste testy nadreaktywności oskrzeli mogą indukować epizody refluksu, co przemawia za udziałem samej astmy w promowaniu GERD. Do osłabienia mechanizmów antyrefluksowych prowadzą związane z zaostrzeniami astmy wzrost ujemnego ciśnienia w klatce piersiowej oraz „pułapka powietrzna”, a także niektóre doustne leki rozszerzające oskrzela, zwłaszcza teofilina. Obie choroby mogą oddziaływać na siebie na zasadzie błędnego koła, co pociąga za sobą implikacje terapeutyczne. Nie ma jednak jednoznacznych danych z badań randomizowanych o skuteczności antyrefluksowej terapii farmakologicznej i chirurgicznej. Najnowsze dane z piśmiennictwa nie potwierdzają pozytywnych rezultatów takiej terapii w grupie astmy trudnej, w której dotąd rekomendowano wdrożenie leczenia dużymi dawkami IPP. Nadal brak jest przekonywają- cych danych dotyczących roli niekwaśnego i/lub żółciowego refluksu w astmie. Konieczne jest udoskonalenie i standaryzacja metod diagnostycznych oraz protokołów terapeutycznych pozwalających wyodrębnić grupę pacjentów, u których terapia antyrefluksowa przyniesie najlepsze efekty dla kontroli astmy.

The influence of relativistic effect upon chemical properties of element 104 is discussed. An original method of measurements of adsorption on the surface of thin film of cobalt ferrocyanate was developed and applied for the studies of 104{sup 4+} hydrolysis. Results of this experiments indicate that in the Group 4 tendency to hydrolysis decreases in the order 104{sup 4+}>Zr{sup 4+}>Hf{sup 4+}. The results were explained on the basis of relativistic effect. Unexpected chemical properties of element 104 in aqueous solutions indicate, that due to relativistic effect element 104 differs distinctly from its congeners - Zr and Hf. In contrary it becomes similar to the lightest element in the Group, Ti, through atomic mass of latter is 213 unit less. (author). 119 refs, 22 figs, 7 tabs.

Effect of pre-crop on severity of Fusarium head blight (FHB) and content of mycotoxins in grain of spring wheat was studied. Pre-crops were grain maize and winter rapeseed. In years, when conditions were favorable for FHB development, an increased severity of wheat head infections was observed...... depended on weather conditions. Rainfall and relative humidity during heading and anthesis had the strongest effect on results obtained during three years of study....

In some patients investigated by radionuclide ventriculography poor labeling efficiency of red blood cells with technetium {sup 99m}Tc is observed. Among possible mechanisms responsible for this phenomenon, the pharmacological treatment applied to the patients should be taken into consideration. The aim of the study was to define the effect of selected drugs used in CAD on technetium binding efficiency by erythrocytes in vitro. Blood samples were obtained from 40 normal individuals receiving no medication. The effect of the following drugs were examined: Aerosonit, Isoptin, Bemecor, Dopegyt, Enarenal, Binazin, Furosemid, Aspirin, Vitamin E and Propranolol. Only Enarenal and Vitamin E proved to have no effect on technetium binding efficiency. The most expressed reduction was observed in experiments with Aerosonit, Furosemid and Propranolol and the smallest changes were found in blood samples with Bemecor, Binazin and Aspirin. The results of the study suggest that pharmacological treatment may influence the quality of scintigraphic images obtained with radioisotope ventriculography. For that reason the medicines applied to the patients should be as much as possible reduced or withdrawn for at least several days before examination. (author) 23 refs, 4 figs, 2 tabs
