OBJECTIVE To assess the effects of oxygen free radicals on liver regeneration in rats after 80% hepatectomy. DESIGN Open laboratory study. SETTING Institute of Biomedical Sciences, University of Milan, Italy. MATERIAL Female Sprague-Dawley rats. INTERVENTIONS After laparotomy 122 rats had ischaemia induced by clamping of the portal vein and hepatic(More)
To study whether or not the autonomic nervous system influences the defense mechanisms of the gastric mucosa, groups of Sprague-Dawley rats were given stimulants and inhibitors of the different components of the vagus and celiac nerves before administration of absolute or 70% w/v ethanol. The effects of vagotomy and sympathectomy on “adaptive(More)
The inhibition of the H-reflex of the Soleus (Sol) muscle that takes place during and after voluntary release of Sol muscle has been attributed to presynaptic inhibition of autogenetic spindle afferences. In the present study, the time-relationship between onset of H-reflex depression and termination of Sol contraction was investigated to ascertain whether(More)
The lack of callosal fibres between homotopic areas of the hand in the sensorimotor cortex in man and its possible functional correlates were investigated in normal adult subjects by comparing simple reaction times (RTs) of voluntary movements triggered by a somaesthetic stimulus to the same or opposite side of the body. An air jet was delivered to the skin(More)
We have examined the effects of oxygen free radicals, generated by xenobiotics administration, ischaemia-reperfusion or sepsis, on the healing of skin or intestinal wounds in rats. We found that 5 days after operation there was a significant decrease in the wound breaking strength in rats treated with phenazine methosulfate, zymosan, ischaemia-reperfusion(More)
One case has been described of acute thrombosis of bilateral femoral anastomotic pseudoaneurysm. The clinical finding of bilateral acute ischemia of the lower limbs required urgent surgical treatment. The operative technique consisted of excision of anastomotic aneurysms and replacement by a new segment of prosthesis with an end-to-end anastomosis to the(More)
OBJECTIVES To describe the fluctuating high velocity vestibular ocular-reflex (VOR) during the Ménière's attacks and correlate those features with pathophysiology. PATIENTS A patient with unilateral Ménière's disease (MD) was evaluated closely during and after acute vertigo episodes. MAIN OUTCOME MEASURES The spontaneous nystagmus and the dynamic VOR(More)
BACKGROUND On the basis of personal experience and studies, the importance to diagnose quickly the seriousness of an acute pancreatitis with the help of simple and credible criteria of evaluation is underlined. It's also underlined the help of endoscopic papillosphincterotomy in the initial phase of a biliary pancreatitis; in fact this exam permits to(More)
We studied the effect of a new prostaglandin analogue, 9-hydroxy-19,20-bis-norprostanoic acid (rosaprostol), on the duodenal mucosa of humans after administration of 40% ethanol. Eighteen healthy volunteers entered the study, which followed a blind cross-over design. At time 0 all the volunteers received rosaprostol or placebo; 5 minutes later, 40% ethanol(More)
