The corpuscles attacked become pale by the destruction of hæmoglobin, swell up and disintegrate, the hæmoglobin becoming converted into granules of black pigment inside the parasite.
Death from the inhalation of illuminating gas is due to the carbon monoxide contained in this, forming a firm chemical union with the hæmoglobin of the red corpuscles so that the function of these as oxygen carriers is stopped.
The hæmoglobin which they contain combines in the lungs with the oxygen in the inspired air, and they give up this indispensable substance to the cells everywhere in the body.
The result is that in these tissues the oxygen pressure is very low, and when the oxygen-laden hæmoglobin reaches them the association of the hæmoglobin with oxygen is at once broken up and the oxygen set free in the tissue.
It is found that when hæmoglobin is brought in contact with oxygen, under sufficient pressure it will form a chemical union with it.
If the oxygen is above a certain rather low pressure, the union will take place; while if the pressure be below this point the union is at once destroyed, and the oxygen leaves the hæmoglobin to become free.
The hæmoglobin is a normal constituent of the blood, and, being red in colour, gives the red colour to the blood.
The blood coming to the lungs contains hæmoglobin, and since the oxygen pressure in the air is quite high, this hæmoglobin unites at once with a quantity of oxygen while the blood is flowing through the air-vessels.
When blood is removed from the body the hæmoglobin is readily separated from the corpuscles by various agents, and is then dissolved in the plasma, which becomes lac-colored.
It is probable that a similar transformation of hæmoglobin takes place in the spleen and elsewhere in melanæmia.
This will remove the hæmoglobin and facilitate examination.
Hæmoglobin estimation is difficult owing to turbidity of the blood after dilution with water.
Hæmoglobin is an exceedingly complex substance, but it contains only one-third per cent by weight of iron in organic form.
Iron is only of value in certain forms of anæmia, and the many patent medicines purporting to contain hæmoglobin or organic iron are therefore useless to neuropaths.
By shaking the solution, oxyhæmoglobin is again reproduced, and gives its special absorption bands.
This change is due to the conversion of hæmoglobin into methæmoglobin, and finally into hæmatin.
If we now add a little ammonium sulphide to this solution, we get the spectrum of reduced hæmoglobin, which is a single broad absorption band situated in the interval between the preceding oxyhæmoglobin bands.
Leichtenstern states that the excess in men of hæmoglobin is 7 per cent.
Wertheim[725] describes certain conditions observed by him and mentions an increase in the number of the leucocytes, together with the presence of hæmoglobin and melanin.
This change in color is due to the action on the hæmoglobin of the gases developed by decomposition.
This change in color is owing to a gradual decomposition of the hæmoglobin of the blood.
The red blood discs, which under normal circumstances stain in pure hæmoglobin colour, now take on a mixed colour.
Among the methods for indirect hæmoglobin estimation, that of calculation from the amount of iron in the blood appears to be quite exact, since hæmoglobin possesses a constant quantity of iron of 0.
Diabella calculates, that with the same amount of hæmoglobin in two blood testings, the stroma may effect differences of 3-5 per thousand in the specific gravity.
From these considerations we see how unreliable in pathological cases is the calculation of the amount of hæmoglobin from the amount of iron.
This calculation may be allowed in all cases for normal blood, for here there is a really exact proportion between the amounts of hæmoglobin and of iron.
However for pathological cases this method of hæmoglobin estimation from the iron present is not to be recommended.
Grawitz assumes, by a diminished affinity of the hæmoglobin for the dye.
Hence the estimation of the specific gravity is often sufficient for the determination of the relative amount of hæmoglobin of a blood.
From what has been said, it follows that all variations must correspond with similarly occurring variations in the factors that underlie the amount of hæmoglobin and the number of corpuscles.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "moglobin" in a variety of sentences. We hope that you will now be able to make sentences using this word.
