| propachlor-s-glutathione metabolism by kidneys and ureters of calves. | six anesthetized 2- to 21-d-old male guernsey calves weighing 28 to 61 kg were used in experiments in which either the left kidney was perfused, via the left renal artery, or the left ureter was perfused with metabolites of propachlor (2-chloro-n-acetylacetanilide, a herbicide). the glutathione conjugate of propachlor (2-s-glutathionyl-n-acetylacetanilide) was metabolized by both kidney and ureter to the cysteine conjugate (2-s-cysteinyl-n-isopropylacetanilide). the glutathione conjugate was not ... | 1991 | 2061243 |
| alkaline phosphatase activity and pyridoxal phosphate concentrations in the milk of various species. | because pyridoxal phosphate does not normally cross membranes, it was intriguing that the concentration of pyridoxal phosphate is much higher in goat milk than in human milk. we also noted that, although the total vitamin b-6 concentration of bovine milk was similar to that of caprine milk, the bovine milk had lower pyridoxal phosphate. preliminary data from five alpine goats, five brown swiss cows, five holstein cows and three humans suggested that there was an inverse relationship between pyri ... | 1992 | 1453218 |
