BACKGROUND Intestinal ischemia-reperfusion (I/R) injury is a devastating complication in the perioperative period. Dexmedetomidine is commonly applied in the perioperative period. The authors aimed to determine the effects of different doses of dexmedetomidine (given before or after intestinal ischemia) on intestinal I/R injury and to explore the underlying mechanisms. METHODS Intestinal I/R ...

  Wax precipitate is one of the most serious issues the oil industry is currently facing, since it can cause some troubles such as increasing of the pressure losses in pipe which subsequently increases the required power for pumpage. To remove this problem, prediction of wax disappearance temperature (WDT) seems necessary. In this study, the pressure influence on the wax disappearance temperatu...

Pet owners desire treats with adequate nutritional profiles, functional benefits, long-lasting properties and an interactive nature. Therefore, it is pivotal to understand the digestion characteristics of treats produced by different processing methods and having variable nutritional composition. The objective of the present study was to measure in vitro disappearance characteristics of selecte...

Aims: The aim was to study the elimination and Phase 2 biotransformation of 4'-hydroxy-4-methoxychalcone ( 1 ) its bis-Mannich analog in small intestine rat. Background: Earlier studies indicated that chalcones are promising starting points for drug design. Aminomethylation drugs is considered improve their delivery into human body. Objectives: To set up validated HPLC-UV methods quantitate inv...

The influence of volatile fatty acids on the ecology of the bacterial flora of the mouse intestinal tract has been studied in three situations where large fluctuations in the composition of the microflora have been observed. Young mice were shown to ingest solid food particles when 11 days old; this correlated with the appearance of strictly anaerobic fusiform bacilli in the intestinal lumen an...

The efficacy of orally given bicyclomycin on shigellosis was studied in rhesus monkeys infected with Shigella fIexneri 2a. All the animals developed lethal infection after rectal inoculation of the virulent strain 5503. Bicyclomycin and the kanamycin control were given orally at daily dosage of 40 mg;kg for a period of 5 days beginning 24 hours after the inoculation. Bicyclomycin compared favor...

The development of the intestinal flora in newborn infants starts during birth when the aseptic gastrointestinal tract of the fetus is inoculated by bacteria from the mother’s intestinal and vaginal flora. This leads to a diverse flora comprising Bifidobacteria, Clostridia, and gram positive Cocci (Heine et al., 1998). After this first inoculation, the flora changes rapidly, presumably under th...

BACKGROUND The clinical significance of intestinal spirochetosis is uncertain, therefore the aim of the present paper was to assess the prevalence of histological intestinal spirochetosis in patients with and without chronic watery diarrhea and to evaluate its clinical relevance. METHODS A prospective diagnostic work-up of intestinal spirochetosis was made on biopsy samples taken from patient...
