BACKGROUND Iodine is a naturally occurring element commercially available alone or in a multitude of products. Iodine crystals and iodine tincture are used in the production of methamphetamine. Although rarely fatal, iodine toxicity from oral ingestion can produce distressing gastrointestinal symptoms and systemic symptoms, such as hypotension and tachycardia, from subsequent hypovolemia. OBJ...

chronic plaque-type psoriasis may be difficult to control without the use of potent systemic therapies that are accompanied by systemic toxicity. mycophenolate mofetil is a novel agent that may be effective in the treatment of chronic plaque type psoriasis. our purpose was to investigate of the safety and efficacy of oral mycophenolate mofetil in the treatment of chronic plaque-type psoriasis. ...

There is currently no standard method for delineating the oral mucosa and most attempts are oversimplified. A new method to obtain anatomically accurate contours of the oral mucosa surfaces was developed and applied to 11 patients. This is expected to represent an opportunity for improved toxicity modelling of oral mucositis.

Self-assembled cholesterol-asplatin-incorporated nanoparticles (SCANs) were prepared for oral delivery of a Pt(IV) prodrug. SCANs exhibit high gastrointestinal stability, sustained drug release and enhanced cell uptake. The oral bioavailability of SCANs was 4.32-fold higher than that of free Pt(IV) prodrugs. The oral administration of SCANs efficaciously inhibits tumor growth with negligible to...

BACKGROUND 6-Mercaptopurine and its prodrug azathioprine are effective medications for refractory inflammatory bowel disease. However, use of these drugs has been limited by concerns about their toxicity. Colonic delivery of azathioprine may reduce its systemic bioavailability and limit toxicity. AIM To determine the bioavailability of 6-mercaptopurine after administration of azathioprine via...

It is well known that intravenous administration of lipopolysaccharide (LPS) induces severe toxicity in mammals. The maximum tolerated dose of intravenous administration of LPS in humans is reported to be only 1 to 4 ng/kg body weight. However, oral administration of a high dose of LPS caused no toxicity or systemic inflammation in other mammals, birds, or fish. Two weeks of oral administration...
