Stercorary aseptic peritonitis due to diastatic caecal perforation: Computed tomography findings

2006

Caecal perforation is a complication secondary to colon obstruction. It may present with insidious clinical features and may be associated with chronic constipation. The event may become severe due to the peritonitic development. We present a case of caecal perforation associated with sub-occlusive carcinoma of the left colon and hypotonic colitis caused by chronic lavative abuse, demonstrated with Computed Tomography.

Somatic Hybridization in the Family Apocynaceae (Catharanthus, Rauwolfia, Rhazya, and Vinca Species)

1994

The Apocynaceae family includes about 2000 species belonging to approximately 200 genera (Takhtadjan 1981). The majority of species originate in the tropics, only a few of them are common to Europe (Vinca minor, V. herhaceae, V. major, genus Trachomitum).

Rhein stimulates active chloride secretion in the short-circuited rat colonic mucosa.

1988

In a short-circuited mucosa-submucosa preparation of the rat descending colon with preserved Meissner's plexus mounted as an everted sac rhein transiently increased the potential difference and short-circuit current (Isc) when administered serosally and mucosally, but serosal application was more effective. Maximal effects were obtained at rhein concentrations of 1.6 X 10(-4) and 3 X 10(-4) mol/l. Net chloride absorption was decreased. Indomethacin (5 X 10(-6) mol/l) did not inhibit the increase of Isc, but omission of calcium from the serosal side as well as tetrodoxin (2 X 10(-7) mol/l) decreased it by 50 and 60%. Mechanical removal of Meissner's plexus partly blocked the effect of rhein,…

Intestinal filtration as a consequence of increased mucosal hydraulic permeability

1980

Two mechanisms have been proposed to explain the secretory action of laxative compounds in the intestine: 1. increase of the intracellular amount of cyclic adenosine monophosphate due to stimulation of the adenylate cyclase system and 2. inhibition of intestinal transfer processes, in particular the Na,K-ATPase activated sodium absorption. In a set of in vivo and in vitro experiments in rat colon it could be demonstrated that dihydroxy bile acids (deoxycholate) and diphenolic laxatives (oxyphenisatin) enhance the hydraulic permeability of the mucosal tissue. The permeability changes take place--and there is good experimental evidence--at the zonulae occludentes which bind the epithelial cel…

Catarsi ed Ethos. La musica tra formazione del carattere e cura dei mali nella Grecia antica

2022

Nella Grecia antica la musica è presenza costante e riguarda tutti gli aspetti del sapere. L’idea di un influsso esercitato sull’uomo, e persino sulla sua salute, trova espressione nella nozione di catarsi e nella dottrina dell’ethos, secondo cui la musica esplica un’azione psicagogica in base alle harmoníai («scale musicali») seguite dalle composizioni, e agli strumenti usati. A partire dai riti, la catarsi entra nella riflessione di Platone e di Aristotele. Nel De musica di Aristide Quintiliano, l’analisi della capacità della musica di influire sull’anima si affianca alla speculazione sulle harmoníai e apre la strada alla comprensione del suo influsso sull’indagine medica, definendo nel c…

“Never shake thy gory locks at me” (Macbeth, III.iv.50-51): Objecting to Gestures in Macbeth

2018

International audience; Shakespeare's Macbeth displays a pattern of characters objecting to gestures, be it others' or their own. This includes Macbeth refusing to shake hands with his opponent before the battle, his words to Banquo's ghost quoted in the title above, Banquo's own puzzlement at the weird sisters' placing a finger over their lips, the doctor's suspicions at Lady Macbeth's rubbing her hands and sleepwalking, as well as Malcom's request that Macduff not pull his hat over his eyes. In many of these cases, gesture is pitted against speech, which seems to undermine the classically-derived ideal of "suit[ing] the word to the action, the action to the word" (Hamlet, 3.2.16-18). This…
