The aim of the present study was to evaluate the effect of two chewing gums on the production of volatile sulfur-containing compounds (VSC) in vivo. Fourteen periodontally healthy participants (20-35 years old) were included in the test panel. Test gum 1 (TG1) contained sucrose and Test gum 2 (TG2) contained xylitol and zinc citrate. Two series of tests were conducted with a double-blind cross-...

To identify the effect of L-propionylcarnitine (LPC) on ischemia, 31 fasting, untreated male patients with left coronary artery disease were studied during 2 identical pacing stress tests 45 minutes before (atrial pacing test I [APST I]) and 15 minutes after (APST II) administration of 15 mg/kg of LPC or placebo. Hemodynamic, metabolic, and nuclear angiographic variables were studied before, du...

Regarding the loss of spinal GABAergic inhibition in neuropathic state,we assayed for protein level of the GABA transporters (GAT-1 and GAT-3) and GABAA receptor α1subunit in male wistar rats with chronic constriction injury (CCI) model of neuropathic pain (Bennett method,1988).We also examined whether the GABAA receptor agonist muscimol and glial inhibitor pentoxifylline would modify behaviora...

Fetal respiratory (FRM)and body movement (FBM) were studied on a transverse cross-section of the fetal upper-abdomen and plotted on a magnetic tape using an event marker. A total of 8 normal and 8 insulin-dependent pregnancies between 29 and 39 weeks was studied. In normal pregnancies, the % incidence of FRM and FBM was calculated from recordings which started 30 minutes before the beginning of...

Oral glucose tolerance tests were performed in healthy infants, aged one to 29 days. Capillary blood samples were obtained from heel stabs for estimation of glucose and insulin immediately before and 30, 60 and 120 minutes after the administration of glucose (2.0g per kg body weight). The younger infants tended to have delayed and diminished insulin responses to a glucose load than did older in...
