spermine/diarrhea

Intractable diarrhoea is a severe condition of early infancy producing prolonged food intolerance, massive watery diarrhoea and malnutrition. Although the etiology remains unknown in more than half of the cases, a basic physiopathological mechanism appears to be a variable inhibition of the

The dose effects of continuous alpha-difluoromethylornithine (DFMO) infusion on red blood cell (RBC) polyamine levels, host toxicity and tumor growth were determined. Male rats with and without a transplantable methylcholanthrene-induced sarcoma received intravenously either 0.45% NaCl or DFMO at

The syntheses of a group of spermine polyamine analogues and their evaluation as antidiarrheals are described. Each compound was assessed in a rodent castor oil-induced diarrhea model for its ability to reduce stool output and weight loss in a dose-dependent manner. The spermine pharmacophore is

The evaluation of a group of polyamine analogs as agents to ameliorate diarrhea-predominant irritable bowel syndrome is described. Each compound was assessed when administered subcutaneously in a psychological stress-induced model of irritable bowel syndrome in rodents for its ability to reduce

The effects of increasing environmental temperature and of exercise on some biochemical characteristics of the intestinal mucosa were analyzed in hamsters to determine whether damage occurs to the intestine during exercise, because long-distance runners complain of cramp, diarrhea, or retrostaltic

Clinical and experimental data suggest that erythrocyte (RBC) polyamine (PA) levels are markers of tumor proliferation during total parenteral nutrition (TPN). The purpose of this experiment was to determine whether the inhibition of PA synthesis during TPN was greater in tumors than in normal host

To explore the origin of diarrhea or constipation in human Duchenne muscular dystrophy (DMD), the effect of the inhibition of e- , i-, and n-nitric oxide synthase (NOS) on the motility of proximal and distal segments of colon of muscular dystrophy (mdx) and control mice was studied. The frequency of

OBJECTIVE N(1),N(11)-diethylnorspermine (DENSPM), a synthetic analog of the naturally occurring polyamine spermine, can induce polyamine depletion and inhibit tumor cell growth. The objectives of this phase I study were to assess the safety, maximum-tolerated dose (MTD), pharmacokinetics, and

Purpose: Polyamines are essential for the sustained proliferation and biomass required by tumor cells. Bis-alkylated polyamine analogs are nonfunctional competitors of natural polyamines. Of these, PG-11047, a second-generation unsaturated analog of the polyamine

The obligate anaerobe, spore forming bacterium Clostridioides difficile (formerly Clostridium difficile) causes nosocomial and community acquired diarrhea often associated with antibiotic therapy. Major virulence factors of the bacterium are the two large clostridial toxins TcdA and TcdB. The
