Various tests of psychomotor performance were carried out in a group of 16 healthy male volunteers given a standardized preparation of Korean ginseng (G 115; 100 mg twice a day for 12 weeks) and in a similar group given identical placebo capsules under double-blind conditions. A favourable effect of G 115 relative to baseline performance was observed in(More)
DSP-4, a neurotoxin which produces a marked and long-lasting depletion of norepinephrine (NE) in the central nervous system, was given in a dose of 50 mg/kg by i.p. route to rats prepared for chronic sleep recordings. Light sleep was significantly increased and REM sleep decreased during the first 2 days following DSP-4. Thereafter, REM sleep showed a(More)
A new HPLC assay method was used to investigate the pharmacokinetics of asiatic acid after oral administration of the total triterpenic fraction of Centella asiatica in single doses (30 or 60 mg) and after a 7-day treatment (30 or 60 mg twice daily). Twelve healthy volunteers received each treatment following a randomized cross-over design with trials(More)
Since a great deal of confusion surrounds the different uses made by clinicians, pathologists, and biologists of the term, this paper clarifies the concept of "early" cancer of the larynx. Clinically, this is usually a glottic neoplasm in which full cordal mobility is still present; early supraglottic cancer is infrequent, and usually a chance finding.(More)
The effect of hyoscine on the peristaltic activity of the proximal and distal ileum of the guinea-pig was studied. Hyoscine strongly impaired peristalsis as indicated by the elevation of the threshold pressure and by the increased number of incomplete peristalses and blockades. Functional activity of the circular musculature was more markedly impaired.(More)
AIM The aim of this study was to analyze the long-term results of the surgical management of craniopharyngioma in children by reviewing a series of patients consecutively treated in a single institution, and to assess the efficacy of intratumoral chemotherapy with interferon-alpha. METHODS Sixty-one paediatric patients (38 males and 23 females; mean age:(More)
Experiments were carried out in-vitro using segments of guinea-pig ileum, taenia caeci, ureter and detrusor. In the ileum, oxybutynin (30, 100 nM) competitively antagonized acetylcholine-induced contractions but did not alter those induced by histamine. Higher concentrations of oxybutynin (up to 10 microM) induced a non-competitive depression of responses(More)
Hyperinsulinemia and insulin resistance are common features of obesity in humans and experimental animals. It has been demonstrated that metformin, an antihyperglycemic agent, decreases hyperinsulinemia and insulin resistance leading to decreased adiposity in obese and non-insulin-dependent diabetes mellitus (NIDDM) adults. To evaluate the antiobesity(More)
Some mitochondrial enzymatic activities (succinate dehydrogenase, NADH cytochrome reductase, cytochrome oxidase) were studied in the gastrocnemius and soleus muscle of the rat. The modifications of the enzyme activity, induced by endurance training, were found to be functions of 1) daily work load and 2) total training time. The treatment with an effective(More)
