Systematic analysis of esophageal pressure topography in high-resolution manometry of 68 normal volunteers

2013

Summary The introduction of high-resolution manometry (HRM) has been a significant advance in esophageal diagnostics. Normative values however are currently based upon a single set of published reference values, and multiple new metrics have been added over the past several years. Our goal was to provide a second set of ‘normal-values’ and to include all current metrics suggested by the 2012 Chicago classification. Sixty-eight subjects without foregut symptoms or previous surgery (median age 25.5 years, ranging from 20–58 years, 53% female) underwent esophageal motility assessment via an established standardized protocol. Normative thresholds were calculated for esophago-gastric junction (E…

AIM: To assess the esophageal motility in patients with irritable bowel syndrome (IBS) and to compare those with patients with autoimmune disorders. METHODS: 15 patients with IBS, 22 with systemic lupus erythematosus (SLE) and 19 with systemic sclerosis (SSc) were prospectively selected from a total of 115 patients at a single university centre and esophageal motility was analysed using standard manometry (Mui Scientific PIP-4-8SS). All patients underwent esophago-gastro-duodenoscopy before entering the study so that only patients with normal endoscopic findings were included in the current study. All patients underwent a complete physical, blood biochemistry and urinary examination. The gr…

Ein gestieltes D�nndarmsegment zum zirkul�ren Ersatz des extrahepatischen Gallengangs bei erhaltener papill�rer Passage

1991

The effect of a small bowel segment as a extrahepatic bile duct replacement was examined in 12 pigs followed-up for a period of 420 days. No complications, either during the operation or postoperatively, were observed in any of the animals. The laboratory parameters were within normal range over the entire observation period of 420 days. After 2, 6, and 12 months there was no anastomotic stenosis in the PTC. The intrahepatic biliary tract was not dilated. There was obvious peristalsis of the small bowel transplant towards the papilla of Vater. The autopsy showed that the grafts had healed without any sign of irritation. Histologically the structure of the graft remained undisturbed. There w…

Inhibitory influences of vagal afferences on the oesophageal EMG peristaltic pattern

1987

AbstractThe influence of vagal afferents on the EMG peristaltic pattern was studied in pigeon oesophagus.Bilateral vagotomy did not abolish the primary peristalsis, but induced significant modifications of the peristaltic pattern parameters.Vagal afferent stimulation induced an inhibitory effect consisting of a temporary break or definitive block of the EMG peristaltic activity already in progress.Vagal afferent stimulation also induced a reduction of the spontaneous EMG activity and this effect was abolished either by glossopharyngeal bilateral section or ganglionic block.Likewise vagal afferent stimulation, the crop distension caused inhibitory effects on EMG peristaltic pattern. This eff…

FUNCTIONAL STUDY ON THE ROLE OF TACHYKININS IN COLONIC PERISTALTIC ACTIVITY IN MICE

2009

Because the role of tachykinin receptors in colonic peristalsis remains incompletely understood, we studied the effect of tachykinin receptor antagonists on mouse colonic peristaltic activity. Peristaltic activity was assessed by quantifying the amplitude and interval of distension-induced pressure waves in proximal and distal colon segments of mice using a modified Trendelenburg set-up. We studied the effect of the NK1, NK2 and NK3 tachykinin receptor antagonists RP67580 (2 mM), nepadutant (1 mM) and SR142801 (0.3 mM) respectively. Gradual distension of proximal and distal colon segments induced repetitive rhythmic pressure waves which were blocked by tetrodotoxin (1 mM) and virtually abol…

Utveckling av uttal hos svensk- och tyskstuderande under utlandsstudier

2013

Tämän pro gradu -tutkielman tarkoituksena on selvittää kohdekielisessä maassa tapahtuvan opiskelijavaihdon vaikutuksia ruotsin ja saksan opiskelijoiden ääntämiseen, eli muuttuuko ääntäminen ja millaisia mahdolliset muutokset ovat. Tutkimukseen osallistui neljä ruotsin ja neljä saksan opiskelijaa, jotka olivat opiskelijavaihdossa yhden lukukauden ajan Ruotsissa tai Saksassa. Tutkimusmateriaali koostuu luetusta puheesta, joka kerättiin ennen ja jälkeen opiskelijavaihdon. Nauhoitukset tehtiin kielistudiossa ja molemmilla kerroilla käytettiin samoja tekstejä, jotta foneettisten aineistojen vertailu onnistuisi. Aineisto analysoitiin pääasiallisesti auditiivisesti, mutta tukena käytettiin myös ak…
