The aim of this study was to investigate the variations of vitamin B12 and homocysteine in blood of dairy cows during subacute ruminal acidosis (SARA). On 228 subjects ruminal liquid was collected through rumenocentesis technique and rumen pH was immediately measured by a portable pH-meter. On the basis of pH values all cows were classified (bovine class) in Group A (animals with rumen pH>5.7),...

IN the course of studying the inhibition of the liver tyrosine oxidase system by L-epinephrine and analogsl the desirability of prpearing a ferrous complex of this hormone became apparent . Although Although such a complex has been described empirically in stucües of the effects of cations and anions on .the the oxidation of catecholamines2 4 and by Yogeler5 , no attempts have been reported to ...

BACKGROUND AND OBJECTIVE A new catheter-free outpatient oesophageal pH-meter system (Bravo) has recently been developed. The objective of this study is to test the tolerance, safety and efficacy of the system in the measurement of gastric-oesophageal reflux by comparing it with a conventional pH system. PATIENTS AND METHOD The study was performed on a control group consisting of 10 healthy vo...

The purpose of our study was to assess whether the chemical composition of drinking water in the city of Szczecin, Poland, creates the correct environment in the oral cavity for promoting regeneration processes in the mineralized tissue of teeth. The drinking water samples were collected from a water treatment station, as raw and treatment water, and from consumer’s water pipes. The concentrati...

Hypothesis / aims of study Acidic urine may play a role in the development of symptoms in patients with interstitial cystitis/bladder pain syndrome (IC/BPS) because activation of afferent C-fibres can be triggered by excessive H + ions in acidic urine. In a previous study, which was presented at the AUA in 2009, we demonstrated that urine alkalinisation could be effective for reducing symptoms,...

OBJECTIVE Hydroxyl (OH-) and calcium (Ca++) ion release was evaluated in six materials: G1) Sealer 26, G2) White mineral trioxide aggregate (MTA), G3) Epiphany, G4) Epiphany + 10% calcium hydroxide (CH), G5) Epiphany + 20% CH, and G6) zinc oxide and eugenol. MATERIAL AND METHODS Specimens were placed in polyethylene tubes and immersed in distilled water. After 3, 6, 12, 24, and 48 h, 7, 14, a...
