Bromadiolone damaged the erythrocytes, resulting in a probable saturation of transferrin, a deposit of iron in the connective tissue and in a few cells of the proximal tubules of the kidneys and an increased storage of ferritin in the spleen. In the hepatocytes, mitochondria were distorted, their lipid inclusions being granular; a large depletion of glycogen may be considered a reflection of an elevated phosphorylase a ascribable to the proliferation of the smooth endoplasmic reticulum. In the kidneys, pyelonephritis may be irrelevant to the poisoning of the animals. Bromine could not be detected using microanalytical methods.

Rabbit muscle phosphoglucomutase was irreversibly inactivated upon preincubation with vitamin C (Vit C). Fe(III), NADH.NADH oxidase.Fe(III), or ferritin.Vit C. Substrate, glucose 1-phosphate and Mg2+ afforded partial protection. No altered amino acid could be detected in the inactive enzyme. Enzyme so inactivated was more susceptible to trypsin. More importantly, during inactivation, the enzyme lost up to 70% of its enzyme-bound phosphate; the completely inactivated enzyme retained the remainder of the bound phosphate which was isolatable as phosphoserine residing in the 22-amino acid long tryptic peptide. Free phosphoserine as well as those in phosphorylase alpha and phosphocasein were resistant to the oxidizing system, suggesting that the phosphoserine of phosphoglucomutase is uniquely vulnerable to these treatments. Alternatively, a fraction of the total 1 mol of phosphate in the phosphoform of phosphoglucomutase may not be associated with phosphoserine. Phosphoglyceromutase, which has phosphohistidine at its active site, was also inactivated by the oxidizing system. However, it did not release any of the bound phosphate.

A novel packing for high performance gel filtration chromatography (GFC) was synthesized and characterized. High porosity silica prepared by base-dissolving method was used as the matrix. gamma-(2,3-Epoxy propoxyl) propyltrimethoxysilane was used as the ligand and covalently bonded onto the silica matrix. After acidic hydrolysis, the epoxy groups were converted to the diol groups. Because a condensation tube filled with water at 70 degrees C was used in the grafting reaction, the resulting methanol could easily be discharged from the reaction system to shift the reaction equilibrium to achieve high ligand density. The hydrolysis condition greatly affects ligand density and column efficiency. The high column efficiency is observed when the ligand density is between 2.6 and 3.5 +/- mol/m2. Several proteins, such as cytochrome C, chymotrypsin, ovalbumin, bovine serum albumin, aldolase, ferritin, insulin, gamma-globulin, phosphorylase, actin, carbonic anhydrase, were used to characterize the separation properties of the resulting high performance GFC column. It was shown that the excluded limit of relative molecular mass for the separation of bio-molecules was 300 000. The recovery yield of bovine serum albumin was 99%.
