Investigations of B- and β-hematin

Journal of Inorganic Biochemistry, 1997
The preparation from ferriprotoporphyrin IX (FP) in aqueous acid medium of the related pigments beta- and B-hematin [see G. Blauer and M. Akkawi, Biochem. Mol. Biol. Int. 35, 231 (1995)] is presented under different conditions. Both pigments are characterized by infrared spectra which differ in the range of 1600-1700 cm-1 in their strong bands with ...

B-hematin.

Biochemistry and molecular biology international, 1995
Very rapid production in vitro of a particular type of hematin (B-hematin) with high yield at physiological pH and temperature is presently reported, using a simple chemical system including an organic acid in the absence of any enzyme. B-hematin is characterized by infrared spectra and solubility properties.

Micro-Raman high-pressure investigation on the malaria pigment hematin anhydride (β-hematin)

Journal of Inorganic Biochemistry, 2018
The effect of pressure on the Raman and fluorescence spectra of hematin anhydride (β-hematin) is reported. In a diamond-anvil cell, DAC, with applied pressures up to 41 kbar, the Raman spectrum undergoes a series of intensity enhancements and increases in energy for many of the Raman-active bands up to a pressure of ~27 kbar. At higher pressures, there

Effect of hematin in porphyric neuropathy

Neurology, 1977
Early, intravenous administration of hematin in a patient with acute intermittent porphyria and severe quadriparesis may have produced partial but remarkable improvement of neuropathy, and resulted in simultaneous decline of porphyrin precursors in the blood.

Metalloporphyrins inhibit β-hematin (hemozoin) formation

Journal of Inorganic Biochemistry, 2000
Metal-substituted protoporphyrin IXs (Cr(III)PPIX (1), Co(III)PPIX (2), Mn(III)PPIX (3), Cu(II)PPIX (4), Mg(II)PPIX (5), Zn(II)PPIX (6), and Sn(IV)PPIX (7)) act as inhibitors to beta-hematin (hemozoin) formation, a critical detoxification biopolymer of malarial parasites.

Shotgun Hematinic Therapy-Reply

Archives of Internal Medicine, 1979
In Reply.— Dr Lutz's concluding remark is that my statement "the patient suffers both medically and financially" from the use of shotgun hematinic therapy is totally unsubstantiated, except by rhetoric. Yet, Dr Lutz's entire letter is unsubstantiated rhetoric, most of it erroneous and/or inaccurate.

Hematin: effects on hemostasis.

The Journal of laboratory and clinical medicine, 1990
Extensive studies performed over the past 6 years have shown that a degradation product of hematin produces a unique coagulopathy, characterized by thrombocytopenia with platelet degranulation, alteration in the function of numerous clotting and fibrinolytic proteins, and reversible changes in endothelial cells. With the use of degraded hematin, it can

Hematin Therapy in Acute Porphyria

JAMA: The Journal of the American Medical Association, 1985
To the Editor.— I was interested to read Dr Bissell's answer to the challenging question concerning the use of hematin in the patient with acute intermittent porphyria (AIP) and pregnancy, which would also apply in hereditary coproporphyria (HCP) and variegate porphyria (VP). 1,2 We recently have had clinical experience with this difficult situation.
