Albendazole and Mebendazole Uptake by Isolated Enterocytes

Developmental Pharmacology and Therapeutics, 1992
Uptake of albendazole (ABZ) and mebendazole (MBZ) by isolated rat enterocytes was carried out. These drugs, widely used oral anthelmintics, exhibit a scarce water solubility which reduce its absorption by the oral tract. The present study was designed to assess the captation for ABZ and MBZ in different enterocyte populations isolated from upper to ...

Basement membrane components enhance isolated enterocyte growth

Journal of Surgical Research, 1992
Isolated enterocyte transplantation may have a potential role in increasing intestinal surface area. However, enterocytes are notoriously difficult to grow. Basement membrane components (BMC) promote adherence, migration, and differentiation of enterocytes. Our aim was to determine if BMC enhance enterocyte growth.

Choline Uptake by Isolated Enterocytes of Guinea Pig

The Journal of Nutrition, 1984
Isolated intestinal epithelial cells of guinea pig were employed to study choline transport. Uptake by cells from the whole length of the small intestine was saturable with an apparent Km value of 119 microM and Vmax of 208 pmol/(mg protein X minute). The compound was taken up by ileal cells about three times faster than by jejunal cells.

Transglutaminase activity in enterocytes isolated from pig jejunum

Molecular and Cellular Biochemistry, 1995
Polyamines appear to be involved in the turnover, growth and maintenance of intestinal mucosa integrity. Since polyamines could act -in part at least- through their incorporation into cellular proteins as catalyzed by transglutaminase, we have measured this enzyme activity in villus enterocytes isolated from pig jejunum and in homogenate derived from ...

Riboflavin Uptake by Isolated Enterocytes of Guinea Pigs

The Journal of Nutrition, 1983
Isolated intestinal mucosa cells of the guinea pig were employed to study the intestinal transport of riboflavin. This method provided a direct approach to characterize the mechanism of riboflavin absorption. Riboflavin was taken up by both jejunal and ileal cells in a temperature-dependent process.

Characteristics of spermidine uptake by isolated rat enterocytes

American Journal of Physiology-Gastrointestinal and Liver Physiology, 1989
Eukaryotic cells require polyamines for growth. The supply of polyamines to growing cells may be increased either by new synthesis or increased uptake. We have recently shown that putrescine uptake by isolated rat enterocytes is energy dependent, saturable, and ouabain insensitive. Although putrescine uptake was inhibited by putrescine and cadaverine,

Characteristics of putrescine uptake in isolated rat enterocytes

American Journal of Physiology-Gastrointestinal and Liver Physiology, 1988
Polyamines are necessary for the growth of eukaryotic cells and are supplied either by new synthesis or cellular uptake. To our knowledge, no information is available on polyamine uptake by gastrointestinal cells. In the current study, isolated villous enterocytes from the rat accumulated putrescine to an eightfold concentration gradient.

Ionic dependence of glycylsarcosine uptake by isolated chicken enterocytes

Journal of Cellular Physiology, 1989
AbstractDipeptide transport was studied in chicken enterocytes and its properties compared with those of Na+‐dependent sugar transport. Results showed that 1) isolated cells were capable of accumulating glycylsarcosine (Gly‐Sar) against a concentration gradient (2.5‐ to 3.0‐fold accumulation).

Specific binding of3H-naloxone with isolated rat enterocytes

Bulletin of Experimental Biology and Medicine, 1985
This paper presents data on the specific binding of naloxone with isolated rat enterocytes. Naloxone was bound with the cells in medium 199 containing 1 mg/ml of BSA. The incubation mixture contained 5 x 100 mM /sup 3/H-naloxone and, if indicated, other substances also. Dose dependence of binding of naloxone with rat enterocytes is shown.

Permeability properties of isolated enterocytes from rat small intestine

Biochimica et Biophysica Acta (BBA) - Molecular Cell Research, 1986
Metabolic and permeability properties of enterocytes isolated by treatment of rat small intestine with hyaluronidase or EDTA were compared. No significant difference was observed in the ability of the two types of cell to produce lactate from glucose. However, while cells obtained with hyaluronidase accumulate alpha-methylglucoside, cells obtained with
