BACKGROUND/AIMS Previous studies from our laboratory have revealed impaired intestinal absorption of D-galactose in lipopolysaccharide-treated rabbits. The aim of the present work was to examine the effect of LPS on D-galactose intestinal absorption in vitro. METHODS D-galactose intestinal transport was assessed employing three techniques: sugar uptake in rings of everted jejunum, transepithe...

AIM OF THE STUDY The present study describes antispasmodic, antidiarrheal, bronchodilatory and tracheo-relaxant activities of Artemisia vulgaris to rationalize some of its traditional uses. MATERIALS AND METHODS Crude extract of Artemisia vulgaris (Av.Cr) was studied in the isolated tissue preparations of rabbit jejunum and guinea-pig trachea, as well as in the in vivo castor oil-induced diar...

BACKGROUND To explore the morphological evidence of immunoglobulin G (IgG) participating in intestinal mucosal immunity, 8 healthy adult Bactrian camels used. First, IgG was successfully isolated from their serum and rabbit antibody against Bactrian camels IgG was prepared. The IgG antibody secretory cells (ASCs) in small intestine were particularly observed through immumohistochemical staining...

BACKGROUND Myrsine africana is an herbaceous plant that is traditionally used as appetizer and carminative. Locally, it is used for the treatment of pulmonary tuberculosis, rheumatism and diarrhea by healers. The aims of the current study were to screen the crude methanol extract obtained from the aerial parts (leaves and stem) of M. africana, for antispasmodic actions on isolated tissues and f...

for this study the jejuni of 50 adult (2-4 years), apparently healthy iranian river buffaloes were collectedfrom the abattoir for gross morphology, histomorphology, and histomorphometry. our statistical analysisrevealed that, there are significant (p

a 33-year-old female presented with intermittent abdominal pain and severe attacks of lower gastrointestinal (gi) bleeding since 2 weeks. she has had history of irregular menses in last 3 months. in the labeled rbc-scan study, the bleeding site was detected in left upper quadrant (luq). in surgery, a tumor with the diameter of 2ã—1cm in a 65 cm distance of ligament of trietz was detected. in pa...

The cholera enterotoxin produces intestinal secretion associated with an elevation of tissue levels of cyclic adenosine 3',5'-monophosphate levels of cyclic adenosine 3',5'-monosphosphate (cAMP). The objectives of this study were to determine whether intestinal secretion and cAMP elevation induced by cholera toxin could be prevented, or once initiated, reversed by nicotinic acid, an agent known...

BACKGROUND The aqueous-methanolic extract of Amaranthus spinosus (A. spinosus Linn.,) whole plant, was studied for its laxative, spasmolytic and bronchodilator activities to validate some of its medicinal uses. METHODS The crude extract of A. spinosus was studied in-vivo for bronchodilator and laxative activities and in-vitro using isolated tissue preparations which were mounted in tissue bat...
