It was shown that 42.1% of the strains were producers. On the other hand Delayed rabbit skin permeability assay, Rabbit ligated ileum and the enlargments of mouse thymus were done to study heat labile enterotoxin. Results revealed that 36.84% of isolates were producers. Finally, to determine the nature of effect of enterotoxins on intestinal cells a comparison was made on histological section and control animals. No variations were noticed between untreated and negative animals. However, great differences were noted between intestinal tissue of positive suckling mice and others .A destroyed villi layer was noted with the appearance of red corpuscles. Therefore, we conclude that the enterotoxin is cytotoxic to the intestine.

Rafidain Journal of Science, 2005, Volume 16, Issue 10, Pages 210-227
DOI: 10.33899/rjs.2005.43336

It was found that different derivatives from Triazoles produced locally can be used instead of the imported cytokinins in the medium for initiation of cell suspension and single cell of lettuce plant.
Addition of NAA to MS media containing the triazoles derivative enhanced greatly the initiation of cell suspension and division better than the effect of standard growth regulators. Moreover, these compounds sustain the cell division in the systems used. The density of the cells in the suspension medium reached 21.1 X 103 cell/cm3 in the presence of compound E, 17.0 X 10-3 cell/cm-3 with compound G and 11.1 X 103 cell/cm3 with compound F in contrast with 8.8 X 103 cell/cm3 in the standard medium after 6 days of growth.
The results indicate that addition of these compounds increased greatly the viability of the single cell system in the same way as in the case of the standard medium. Addition of these compounds instead of standard cytokinins with NAA stimulates the growth of the cells grown on Agar-Drop system with the formation of callus with the lapse of growth period. The initiation of callus by this method was between18 to 47 % as compared with 63% in the standard medium.
It can be concluded that these prepared compounds can be used as a new growth regulators instead of the standard cytokinins. These compounds can be used in the other tissue culture system for different plants

This study was conducted to investigate the effect of Tannin and anemia on dietary iron absorption and som physiological features in weanling albino male rats, Forty eight rate were used as a biological model for this study. These rats were randomly divided into two major groups (Anemic and Healthy). First group get anemic by induce bleeding from Retro-ocular vein. Each major group contains 24 rats were divided into 4 group, each subdivided group fed one type of diet (4 types of diets were used: Standard Diet, Basic Diet with Tannin, High Density Diet and Low Density Diet). Those diets fed to rats for 10 days, then estimation of dietary iron absorption and nutritional status were performed for anemic and healthy rats by estimating Hemoglobin concentration, Body weight changes, Diet and dietary iron intake weights, And eliminated feces and fecal iron weights, Analysis of variance showed that anemic rats absorb iron more than healthy one, Tannin decrease iron absorption in both anemic and healthy rats. Finally, high density diet is more efficient than other diets in improving nutrition status in anemic rats.
