Data from 75 bird species weighing between 6 g and > 16 kg confirmed a supposition that the amount of haemoglobin per unit surface area of erythrocyte was not dependent on body mass. It showed a constancy across the range reflecting adjustment of the total surface area of erythrocytes in relation to blood haemoglobin concentration. This conclusion is based on an inverse correlation between the numbers and sizes of red blood cells.

The literature provides all the data needed to calculate the ratio between the amount of haemoglobin and the total surface area of erythrocytes in 54 species of mammals ranging in body mass from 2.5 g to more than 1000 kg. Analysis shows that the concentration of haemoglobin (Hb; g%) does not defend on the body mass ofthe mammals studied. The number of erythrocytes in 1 mm of blood (RBC; 10 x mm ) is significantly lower, and the diameter of these cells significantly higher, among larger mammals as opposed to smaller ones. The result is that the total surface area of erythrocytes in 1 mm of blood (TSAE; mm x mm ) is significantly lower among larger mammals, while the Hb/TSAE ratio (pg x ^m- ) is significantly greater. These results point to the smaller size of erythrocytes of smaller mammals permitting much greater numbers to exist, thereby producing a greater TSAE and smaller Hb/TSAE ratio. The greater total surface area of red blood cells per unit volume of blood in small mammals can in turn be presumed to allow for full saturation of haemoglobin by oxygen, even where the period of contact between erythrocytes and air in the lungs is shorter than in their larger counterparts.

The ferryl derivatives of hemoglobin are products of the reactions of oxy- and methemoglobin with hydrogen peroxide. Ferryl hemoglobins, either with or without a radical site on the protein moiety, are oxidizing species. Plant polyphenols, flavonoids, have been shown to act as antioxidants in vivo and in vitro. Reactions of met- and oxyhemoglobin with hydrogen peroxide in the presence of catechin, quercetin and rutin were studied. These flavonoids accelerated reduction of ferryl hemoglobin to methemoglobin. The rate constants of the reactions of ferryl hemoglobin with catechin, quercetin and rutin were in the order of 102 M-1 s-1, i.e. similar to the rate constants of ferryl hemoglobin with intracellular reducing compounds like urate or ascorbate. The beneficial effect of flavonoids against oxidative damage of hemoglobin caused by hydroperoxides, reported in the literature, is probably, at least in part, connected with the ability of flavonoids to scavenge ferryl hemoglobin.

We have previously reported on the identification and characterization of the Porphyromonas gingivalis A7436 strain outer membrane receptor HmuR, which is involved in the acquisition of hemin and hemoglobin. We demonstrated that HmuR interacts with the lysine- (Kgp) and arginine- (HRgpA) specific proteases (gingipains) and that Kgp and HRgpA can bind and degrade hemoglobin. Here, we report on the physiological significance of the HmuR-Kgp complex in heme utilization in P. gingivalis through the construction and characterization of a defined kgp mutant and a hmuR kgp double mutant in P. gingivalis A7436. The P. gingivalis kgp mutant exhibited a decreased ability to bind both hemin and hemoglobin. Growth of this strain with hemoglobin was delayed and its ability to utilize hemin as a sole iron source was diminished as compared to the wild type strain. Inactivation of both the hmuR and kgp genes resulted in further decreased ability of P. gingivalis to bind hemoglobin and hemin, as well as diminished ability to utilize either hemin or hemoglobin as a sole iron source. Collectively, these in vivo results further confirmed that both HmuR and Kgp are involved in the utilization of hemin and hemoglobin in P. gingivalis A7436.

This study aims to describe the hemoglobin Fannin-Lubbock-I, which has a rare mutation substituting the amino acid glycine with aspartic acid at codon 119 of the β-globin chain. A Bengalee Hindu Brahmin family from Kolkata in West Bengal was the focus of this study. Molecular analysis using ARMS-PCR and direct DNA sequencing revealed the presence of a GGC > GAC mutation in codon 119 of the β-globin gene in a heterozygote state in three women of the same family. This is the first report of the hemoglobin Fannin-Lubbock-I from India. Our results will help to identify this mutation, which is relatively infrequent in our population.

The aim of the study was to evaluate the usefulness of the reticulocyte indices in the diagnosis of anaemia in piglets. The piglets in group I (n=16) were treated with iron dextran (200 mg of Fe, i.m.) at the age of 16 d. In group II (n=16), piglets at the age of 3 d received 100 mg of Fe and then at the age of 22 d - 200 mg of Fe. The piglets in group III (n=16) received 200 mg of Fe at the age of 3 d. From the 7 d of age, all the piglets had access to creep feed. In group I, there was a decrease in red blood cell indices and the piglets developed anaemia. These piglets had a lower growth intensity compared to piglets of groups II and III. In comparison with Hb, PCV, and RBC, the reticulocyte indices (haemoglobin concentration in reticulocyte and index RET-Y) reflexed more rapidly impaired erythropoiesis and in the case of mild iron deficiency (group II) they reacted more effectively to iron treatment.
