| Variation of Quadrupole Splitting in Modified Oxyhemoglobin: A Mössbauer Effect Study  | | | Abstract
| Human adult hemoglobin modified by both pyridoxal-5'-phosphate and glutaraldehyde in the oxy-form was studied by Mössbauer spectroscopy. Mössbauer spectra were measured at 87 and 295 K (hemoglobin in lyophilized form) and at 87 K (hemoglobin in frozen solution). The values of the quadrupole splitting for modified oxyhemoglobin were found to be lower then those of oxyhemoglobin without modifications in lyophilized form and frozen solution, respectively. The Mössbauer spectra of modified oxyhemoglobin were also analyzed in terms of the heme iron inequivalence in a-and /3-subunits of the tetramer. Differences of the tendencies of temperature dependencies of quadrupole splitting for modified and non-modified oxyhemoglobin in lyophilized form were shown. | | |

| Carnivora: The Primary Structures of Adult Lion (Panthern leo) Hemoglobins  | | | Abstract
| Complete amino acid sequences of lion (Panthera leo) hemoglobins are reported. Polyacryl amide gel disc electrophoresis at pH 8.3 and also in the presence of 8 M urea and Triton-X100, RP-HPLC, liquid and gas phase amino acid sequenator. and FAB Mass spectrometer are used. Sequences are aligned with human hemoglobin (Hb A) and compared with other hemoglobins of felidae. | | |

| Hemoglobins in Single Chick Erythrocytes as Determined by a Differential Elution Procedure  | | | Abstract
| The switch from embryonic to adult hemoglobin (Hb) has been studied in vivo by a correlated cytological and electrophoretic analysis of circulating red blood cells from early, purely embryonic-Hb stages to purely adult-Hb stages including the adult chicken. It has been discovered, by using an acid buffer treatment that selectively elutes adult but not embryonic Hb from intact red blood cells, that embryonic and adult Hbs occur together in single cells, and that the switch occurs simultaneously in all cells. These results together with knowledge of the chick erythroid cell dynamics and ontogenetic titers indicate that the initiation of adult Hb synthesis occurs in the circulation in cells previously committed only to embryonic Hb synthesis. | | |

| Embryonale Hämoglobine der Säuger: Die Sequenzen der s-und ^-Ketten vom Hausschwein {Sus scrofa domestica) Embryonic Hemoglobins in Mammals: The Primary Structures o f e-and 5-Chains of the Pig (Sus scrofa dom estica)  | | | Abstract
| The amino-acid sequences of all expressed hemoglobins of the pig embryo are given: Hemo globin Gower I (C2/e 2), Hemoblobin Gower II (oc2/ e 2), Hemoglobin Heide I (C2/>92) and Hemo globin Heide II (a2/<92). The e-and 5-chains were obtained with chromatography on CM-cellu-lose from isolated hemoglobin components. The primary structure was established by sequencing the tryptic peptides in the sequenator: they were isolated using HPLC. The C-chains from pig and human differ in 23, the e-chains in 20 positions. The embryonic globin-gene which express the 5-chains, is a new one in mammals, of e-type and up to now it could only be found in pigs: the amino-acid sequence differ in only 4 positions from the e-chains. Because no y-chains (fetal Hb) are expressed the sequences of all hemoglobins (5 hemoglobin chains forming 5 different hemo globins) of ontogeny in pig are now described. | | |
