OBJECTIVE
To study the regulatory effect of Huoxiang Zhengqi Extract (HZE) on the intestinal mobility in rat model of diarrhea-predominant irritable bowel syndrome (D-IBS).
METHODS
Eighty experimental rats were randomly divided into two parts, forty in each. Rats in one part were used in the carbon
The bovine viral diarrhea virus (BVDV) strains exist as two biotypes, cytopathic (cp) and noncytopathic (ncp), according to their effects on tissue culture cells. It has been previously reported that cell death associated to cp BVDV in vitro is mediated by apoptosis. Here, experiments were conducted
Hemolytic uremic syndrome (HUS) is characterized by microangiopathic hemolytic anemia, thrombocytopenia and acute renal failure. Besides diarrhea-associated HUS, due to verotoxin-producing Escherichia coli, in children HUS without prodromal diarrhea may be associated with other infectious and
Cryptosporidiosis, a diarrheal disease usually caused by Cryptosporidium parvum or Cryptosporidium hominis in humans, can result in fulminant diarrhea and death in AIDS patients and chronic infection and stunting in children. Nitazoxanide, the current standard of care, has limited efficacy in
Between June and October 1982, Vibrio cholerae el tor Inaba phage type Russian 13, resistant to ampicillin (Ap), chloramphenicol (Cm), colistin, neomycin (Nm), kanamycin (Km), gentamicin (Gm), trimethoprim sulfamethoxazole (TMP-SMZ), and tetracycline (Tc), was isolated from 31 children with diarrhea
Given that there was documented evidence of an association between diarrhea and high nitrate ingestion, the authors examined drinking water nitrate concentration and its possible correlation(s) with methemoglobin levels, cytochrome b5 reductase activity, and recurrent diarrhea. In addition, the
Mevinolin reduces cholesterol synthesis by inhibiting 3-hydroxy-3-methylglutaryl-coenzyme A reductase. The safety and effectiveness of this agent was evaluated in a double-blind, placebo-controlled study in 59 healthy men (serum cholesterol 3.88--7.76 mmol/liter) in five centers. Subjects maintained
Genetic variations of the enzymes involved in chemotherapy metabolism in cancer patients may play a role in determining relapse and toxicity risks. Methotrexate is a key drug in acute lymphoblastic leukemia (ALL) treatment; it inhibits DNA replication by blocking the conversion of 5,10 methylene
OBJECTIVE
To study the safety, pharmacokinetics, biologic activity, and preliminary efficacy of the bispecific 5-alpha-reductase inhibitor (LY320236) in prostate cancer.
METHODS
Fifty-one patients with recurrent or metastatic prostate cancer were sequentially (nonrandomly) assigned in cohorts to
The effects of reduced glutathione on the development of choleragenic diarrhea and the activity of glutathione transferase (GT), glutathione peroxidase (GP-GTB and GP-H2O2), superoxide dismutase (SOD), glutathione reductase (GR) in the small intestine and liver of rats with experimentally ligated
The aim of the present study was to evaluate the influence of severe protein-energy malnutrition on the antioxidant defense system in the small and large intestine in rats at weaning. Chronic diarrhea and the subsequent malnutrition were induced by oral intake of a lactose-enriched diet. Twenty rats
The evolution of antimicrobial resistance in Salmonella isolates causing traveler's diarrhea (TD) and their mechanisms of resistance to several antimicrobial agents were analyzed. From 1995 to 2002, a total of 62 Salmonella strains were isolated from stools of patients with TD. The antimicrobial
Tolerance and pharmacokinetics after single-dose administration of atorvastatin, an investigational inhibitor of HMG-CoA reductase, were examined in 22 healthy volunteers in a three-period, partially-blinded study. Participants received capsule and solution doses of atorvastatin (0.5 to 120 mg) and
Specific activities of five enzymes were measured in intestinal mucosa of zinc-deficient rats and compared to activities in appropriate zinc-sufficient controls. Three disaccharidases were found to be significantly reduced in zinc deficiency. Alkaline phosphatase, a zinc metalloenzyme, also showed
CB1954 [5-(aziridin-1-yl)-2,4-dinitrobenzamide] is converted by the bacterial enzyme nitroimidazole reductase (NTR) into a potent cytotoxic bifunctional alkylating agent, which can be delivered to tumors in adenoviral vectors as virus-directed, enzyme prodrug therapy. This report summarizes a Phase
