To clarify the mechanism of castor oil-induced diarrhea, this study was performed by using rats in relation to nitric oxide (NO) and prostaglandin (PG). Castor oil induced diarrhea in all rats within 3 hr in the control group. The pretreatment of NG-nitro-L-arginine methyl ester prevented the
Clostridium difficile infection (CDI) symptoms range from diarrhea to severe toxic megacolon and even death. Due to its rapid acquisition of resistance, C. difficile is listed as an urgent antibiotic-resistant threat, and has surpassed methicillin-resistant Staphylococcus aureus (MRSA) as the most
The novel small molecule, BIT225 (N-[5-(1-methyl-1H-pyrazol-4-yl)-napthalene-2-carbonyl]-guanidine: CAS No. 917909-71-8), was initially identified using a screening strategy designed to detect inhibitors of Hepatitis C virus (HCV) p7 ion channel activity. Here we report that BIT225 has potent
BACKGROUND
Polyhexamethyleneguanidine hydrochloride (PHMG) is an antimicrobial biocide of the guanidine family. In the period from August 2006 to May 2007, more than 12500 patients were admitted to hospital with a history of drinking illegal cheap "vodka" in 44 different regions in Russia, of whom
A patient who consulted because of diarrhea was diagnosed of thyroid medullar carcinoma (TMC) associated to pheochromocytoma. All members of his family were studied for a possible family variety of TMC with a genetic origin. In the 21 family members studied basal and calcium-pentagastrin stimulated
Pathogenesis of cholera diarrhea requires cholera toxin (CT)-mediated adenosine diphosphate (ADP)-ribosylation of stimulatory G protein (Gsα) in enterocytes. CT is an AB5 toxin with an inactive CTA1 domain linked via CTA2 to a pentameric receptor-binding B subunit. Allosterically activated CTA1
A multiplex polymerase chain reaction (multiplex-PCR) to detect and differentiate bovine herpesvirus 1 (BoHV-1) and 5 (BoHV-5) was developed using primers for the gene sequence that encodes the glycoprotein C. The technique was assessed against the BoHV-1 and BoHV-5 cell culture adapted strains, and
Goat's rue (Galega officinalis) leaves and flowering tops contain numerous guanidine derivatives, including galegine which may cause hypoglycemia. Goat's rue is widely used internationally as a galactogogue.[1-4] No scientifically valid clinical trials support this use, although some old, poorly
