Ameliorating effects of herbal formula hemomine on experimental subacute hemorrhagic anemia in rats.
Hemomine (HM) is an herbal mixture consisting of 5 varieties of the hematopoietic herbal extracts (Angelica gigas Nakai, Cnidium officinale Makino, Paeonia lactiflora Pall., Rehmannia glutinosa Liboschitz ex Stueudel, Glycyrrhiza uralensis Fischer).. Anemia has been treated with iron supplements, whereas it could cause adverse side effects such as digestive discomfort. In the present study, HM was applied to SHA rats to test for several activities so as to verify its therapeutic potentials on anemia and digestive discomfort.. Sprague-Dawley rats were assigned to seven groups: (Two controls, two references (ferric hydroxide polymatose (FM) and ferritin extract glycerin hydrate (FA)), three different concentrations of HM, n=8 per groups), and induced subacute hemorrhagic anemia (SHA) through blood exsanguinations once a day for 7 days.. The SHA animal model showed changes in the markers related to classic iron-deficient and regenerative anemia in this experiment. However, the SHA related anemic signs were dose-dependently inhibited by the administration of HM 2, 1, and 0.5ml/kg for 7 days, and more favorably than the equal dosages of FM and FA. In addition, FM and FA showed the typical constipation signs, including reduction of in thickness of the colonic mucosa, in contrast, HM 2, 1, and 0.5ml/kg groups had no effects on the gastrointestinal motilities and the colonic mucous components when compared to the controls. The results suggested that the HM significantly showed to have therapeutic effects in the experimental SHA in rats, and is more potent than the commercial iron supplement through the proliferation of hematopoietic stem cells with reduced digestive discomfort.. Therefore, Hemomine may prove to be a promising hematopoietic and therapeutic agent for anemia.

Increased iron requirement in hemodialysis patients on antiplatelet agents or warfarin.
Many hemodialysis patients receive antiplatelet therapy or warfarin; however, little is known about the effect of this on iron requirements. Given the association of antiplatelet therapy with bleeding we hypothesized that there should be a greater need for iron in such patients, which we tested in this study.. Retrospective 1-year cohort study of 205 chronic hemodialysis patients. The primary outcome variable was total iron dose, which was analyzed according to antiplatelet/warfarin use. Data were also collected on potential confounders, allowing for both unadjusted and adjusted (multiple regression) analysis.. 97/205 patients received antiplatelet/warfarin therapy. This group was older, with a higher incidence of macrovascular disease and diabetes and a higher median C-reactive protein (6.0 vs. 3.75 mg/l). Overall, median iron requirement was 1,300 mg/year. In a multiple regression analysis, antiplatelet/warfarin use was associated with an additional iron requirement of 703 mg (95% confidence interval 188-1,220 mg), with the strongest effect observed in patients with normal inflammatory markers.. We found a high requirement for iron in patients receiving antiplatelet agents/warfarin. We argue that the most likely mechanism for this association is chronic, low-grade blood loss, although further study is required before causality can be established.

Bioavailability of iron from oral ferric polymaltose in humans.
The bioavailability or iron from iron(III)hydroxide polymaltose complex (ferric polymaltose, Fe-PM) was studied in human volunteers with normal or depleted iron stores as well as in patients with iron deficiency anemia. From an oral iron dose of 100 mg neutron activated Fe-PM, starved subjects with depleted iron stores absorbed significantly less (p < 0.003) 59Fe (3.91 +/- 2.24%, mean +/- SD) as compared to the reference, aqueous 59Fe(II) ascorbate solution (13.8 +/- 6.19%). Using non-radiolabeled, commercial Fe-PM no postabsorptive serum iron increase was found after oral Fe-PM (100 mg Fe dosage) in a group of 7 patients with haemorrhagic or posthaemorrhagic iron deficiency anemia. In addition, almost no haemoglobin increase was observed in 9 patients during a 4-weeks treatment period when given Fe-PM (100-300 mg Fe/d) on empty stomach, whereas subsequent treatment with ferrous sulfate (100-200 mg Fe/d) was therapeutically effective (0.15-0.23 g/dl Hb-increase/d). When given 100 or 300 mg Fe/d Fe-PM together with meal, 3 out of 6 patients showed a higher iron utilization rate (3.4-11.9%/d) than given without meal (0.5-7.5%/d). In vitro incubation studies demonstrated that Fe-PM is very stable at neutral pH. A small release of iron from the high molecular weight complex was found only at low pH (< 2). However, high amounts of ionic iron were measured in the reaction tubes after incubating solutions of Fe-PM together with ascorbic acid. This finding could explain the somewhat higher bioavailability of Fe-PM when given with vitamin C containing meals.(ABSTRACT TRUNCATED AT 250 WORDS) Topics: Administration, Oral; Adult; Anemia, Hypochromic; Biological Availability; Ferric Compounds; Ferrous Compounds; Hematinics; Hemorrhage; Humans; Hydrogen-Ion Concentration; Iron; Iron Radioisotopes; Neutron Activation Analysis | 1994 |
