✦ Synopsis


The voluminous literature of the comparative aspects of oxygen-hemoglobin equilibrium has received several complete reviews (Redfield, '33 ; Florkin, '34 ; Prosser, '50).

Krogh and Leitch ('19) reported that, in both fresh and salt water, species of fish which frequently encounter low oxygen tensions have hemoglobins with higher oxygen affinities than those of species which seldom or never encounter low oxygen tensions. Redfield, Coolidge and Hurd ( '26) reported similar findings for several invertebrate species. These authors also pointed out that active species are likely to present hemoglobins with low oxygen affinities and high Bohr effects, while sluggish species are likely to possess hemoglobins with high oxygen affinities and low Bohr effects. Hall and AIcCntcheon ('38) revealed, f o r marine fish, data similar to those of Krogh and Leitch. Hall, Dill and Barron ('36) and Hall ( '37) stated that mammalian and avian species indigenous to the Chilean Andes revealed hemoglobins with higher oxygen affinities than those of their sea level counterparts. The works cited above indicate that the oxygen affinities of specific hemoglobins are correlated with habits and habitats and bear little relevancy to phylogenetic relationships.

This work was done in the laboratories of the Department of Physiology and a Thcse findings were presented as partial fulfillment of the requirements f o r

When hemoglobin is exposed to alkali the globin portion of the molecule is altered resulting in the formation of globin hemochromogen. The rate at which such alkaline denaturation takes place is characteristic of the type of hemoglobin. I n 1934 Brinkman, Wildschut and Wittermans used specificity of

An instrument that accurately measures oxygen consumption (Vow) during field performance is valuable for investigations of physiological workload. Cosmed (Rome, Italy) has introduced such an instrument, the Cosmed K2. In this study the Cosmed K2 was compared with the Oxyconbeta (Jaeger, Breda, The N

We assessed the chromosomal response of insect (mosquito, Aedes albopictus) and mammalian (Chinese hamster ovary, CHO) cells to streptonigrin (SN). Both types of cells were pulse-treated for 20 min with increasing doses of SN and the frequency of chromosome aberrations and sister chromatid exchanges
