Nutrient relationships between Orobanche fasciculata Nutt. and its host Artemisia pygmaea Gray in the Uinta Basin of Utah, USA

Patterns of mineral nutrient uptake and distribution within the roots, stems, and leaves of Artemisia pygmaea and in the vascular parasite Orobanche fasciculata were investigated. All nutrients studied were magnified over concentrations found in the soil into the host and parasite. Nitrogen, phosphorus, potassium, and zinc were magnified along the flow gradient of soil-roots-stems-leaves of the host. All others increased in the roots and then decreased in the stems and leaves. Orobanche fasciculata concentrated phosphorus, potassium, and sodium over soil and root concentrations while excluding to some degree all others.     

Absorption of glycine and proline from the small intestine of rats infected withEimeria nieschulzi

Summary The absorption of glycine and proline through the jejunum and ileum of rats with anEimeria nieschulzi infection was impaired when the amino acids were presented to the mucosal surface as either a mixture or the dipeptide, glycyl-proline.     

Effect of various doses of catecholestrogens on uterine eosinophilia in the immature rat

This paper describes the induction of uterine eosinophilia as well as of deep endometrial edema and increase of uterine wet weight in the immature rat by the catecholestrogens 2-OH-estradiol and 4-OH-estradiol. These effects are thought to be mediated by eosinophils via a specific eosinophil receptor system. 4-OH-estradiol was equipotent with estradiol, whereas the effect of 2-OH-estradiol was significantly weaker.
