An Electrolytic Elemental Iron Powder Effectively Regenerates Hemoglobin in Anemic Rats and Is Relatively Well Absorbed When Compared to Ferrous Sulfate Monohydrate.

Elemental iron powders are used as food fortificants to reduce the incidence of iron deficiency anemia. However, many commercially available iron powders are relatively untested in vivo. The purpose of this study was to determine the hemoglobin regeneration efficiency (HRE) and relative iron bioavailability (RBV) of an electrolytic elemental iron powder (EIP), by treating anemic rats with 14 d iron repletion diets fortified with four different concentrations (12, 24, 36, or 48 mg iron/kg diet) of EIP and bakery-grade ferrous sulfate monohydrate (FS; FeSO4•H2O), or no added iron (control); n = 9-12/group. The HRE of FS was significantly higher (p ≤ 0.05) than EIP at each concentration of dietary iron tested. For EIP, the HREs (ratios) of diets containing 12, 24, 36, and 48 mg iron/kg were 0.356, 0.205, 0.197, and 0.163, respectively. For both EIP and FS, HRE was inversely associated with increasing dietary iron. The RBVs (%) of iron from EIP in diets at 12, 24, 36, and 48 mg iron/kg as compared to FS were 64.5, 59.1, 50.6, and 54.3%, respectively. Overall, findings show that at the concentrations of iron tested, EIP has RBVs greater than 50% and is an effective fortification agent to replenish hemoglobin and correct iron deficiency anemia.

Hemoglobin Regeneration Efficiency and Relative Iron Bioavailability of Four Elemental Iron Powders in Rats.

Effective food fortification strategies using elemental iron powders (EIPs) are needed to combat iron deficiency anemia. The purpose of this study was to determine hemoglobin regeneration efficiency (HRE) and relative iron bioavailability (RBV) of four food-grade EIPs (El-Lyte (EL), Hi-Sol (HS), H-325 (H3), and A-131 (A1)) by treating anemic rats with 14 d iron repletion diets (uncooked and cooked), fortified with a 12, 24, or 36 mg iron/kg diet of the EIPs, ferrous sulfate monohydrate (FS, FeSO4•H2O), or no added iron (control), n = 9-12/group. The ability of EL and HS to maintain hemoglobin for 6 weeks on the 6 mg iron/kg diet was also studied. The dissolution rate of iron from the EIPs was measured in hydrochloric acid at pH 1.0. Compared to FS, the EL, HS, and A1 EIPs had >50% overall RBV, with the following order: HS > A1 > EL > H3 (p ≤ 0.05); the effect of cooking was not significant (p > 0.05). Dissolution testing revealed that the mean RBV of the EIPs was positively associated with the percentage of iron solubility. In the 6-week maintenance study, EL and HS maintained hemoglobin as well as FS. Overall, the findings show that at the concentrations of iron tested, these EIPs are effective fortification agents to replenish hemoglobin and correct iron deficiency anemia.

Effects of Aloe Vera Gel on Red Blood Cell-parameters in Phenylhydrazine-induced Anaemic Wistar albino Rats

Background & objective: Anaemia is the most significant disorder of the blood. Many researchers have developed the concept of using medicinal plants as an alternative source of treatment for anaemia with fewer side effects. Aloe vera, being a medicinal plant, is popularly used as a natural drug in haematological disorders. The present study was intended to observe the effects of Aloe vera gel on red blood cell parameters in phenylhydrazine (PHZ)-induced anaemic Wistar albino rats. Methods: This Experimental study was conducted in Dhaka Medical College, Dhaka from July 2021 to June 2022. A total of 24 healthy Wistar albino rats were selected for the study. After procurement, the rats were initially kept in a standard laboratory condition on a 12/12-hour light/dark cycle for 14 days of acclimatization before 21 days of the experiment. All the rats had free access to basal diet and normal saline during the period of acclimatization and experiment. After acclimatization for 14 days, the rats were divided into three groups-Group A (baseline control group, n = 8), Group B (PHZ-treated group, n = 8), and Group C, the Experimental Group (PHZ-induced and Aloe vera gel treated group, n = 8). To induce anaemia, Group B and Group C received intraperitoneal injection of PHZ at a dose of 0.5 ml/100 g body weight on days 1, 3, 5 and day 7. Moreover, the experimental group (Group C) received Aloe vera gel orally at a dose of 0.6 ml/kg body weight from Day 8 to Day 21. On day 22, rats were sacrificed to test their blood samples for haematologic variables (RBC count, Hb conc., and PCV) and haematological indices (MCV, MCH and MCHC). Result: All the haematological parameters and indices were almost similar among the study groups at baseline (on Day 1). On Day 8, rats of groups B and C demonstrated a drastically reduced count of RBC (2.66 ± 0.53 and 2.69 ± 0.52 million/μl respectively) compared to the rats of group A (8.16 ± 0.76 million/μl). On Day 22, the RBC count in rats of Group C staggeringly increased to 7.63 ± 0.64 million/μl; however, the RBC count in rats of Group B remained almost the same as was found on Day 8. A significant decrease in Hb conc. and PCV in PHZ-induced control on Day 8 compared to that on Day 1 was also observed. The mean MCV in all the study groups on Day 1 was around 50 fl, which abnormally increased to 85 and 87 fl in Groups B and C respectively on Day 8. On Day 22, Group B further exhibited an increase in MCV to > 87 fl. Meanwhile, the MCV in Group C (Aloe vera-treated group) favourably decreased to 55 fl. On the 8th Day of intervention, the MCH level significantly decreased in Groups B and C. Although no significant change in MCH was observed in Group B from Day 8 to Day 22, group C demonstrated a significant increase in the mean MCH to nearly 18 pg during the same period. The mean MCHC significantly dropped to < 23% in Groups B and C on Day 8 from the baseline figure of 34%. While no significant change in MCHC was evident in Group B from Day 8 to Day 22, it significantly improved to about 28% in Group C during the same period. Conclusion: From the study, it can be concluded that Aloe vera has significant erythropoietic potentials which result in the improvement of red blood cell parameters (RBC count, Hb conc., PCV, MCV, MCH and MCHC) in PHZ-induced anaemic rats.

Antianemic Activity of Allolobophora caliginosa Extract against Phenylhydrazine-induced Anemia in Rats

Background:: Anemia is a global hematological disorder. Earthworms have antimicrobial, antispasmodic, antihypertensive, antiallergic, anti-inflammatory, and anticoagulant properties. Objective:: Our study aimed to investigate the anti-anemic activity of the earthworm Allolobophora caliginosa extract (AcE) on phenylhydrazine-induced hemolytic anemia in rats. Methods:: Eighteen adult male albino rats were randomly divided into 3 groups (n = 6 per group) as follows: Control, PHZ, and AcE-treated groups. Induction of anemia was done by intraperitoneal administration of phenylhydrazine (40 mg/kg) for 2 consecutive days. Treatment of AcE by intraperitoneal injection (45 mg/kg) for six successive days. Results:: Treatment of anemic rats with AcE extract caused significant increases in red blood cells (RBCs), hemoglobin (HB), hematocrit (HCT), total protein (TP), albumin, glutathione reduced (GSH), catalase (CAT), and glutathione-S-transferase (GST), as compared to the PHZ group. While, mean corpuscular haemoglobin (MCH), mean corpuscular hemoglobin concentration (MCHC), alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), malondialdehyde (MDA), and nitric oxide (NO) levels significantly decreased after intraperitoneal administration of AcE, when compared to the PHZ group. Liver sections from the AcEtreated group restored the normal micromorphological features of the liver. The expression of caspase- 3 was weak and/or there was no expression in the liver sections from AcE groups. AcE caused a significant reduction in the incidence of DNA damage, which appeared as less DNA in the tails. Conclusion:: The present research sheds light on the antianemic efficacy of AcE in rats. This study reveals that AcE has antianemic activity, which can be linked to its iron and branched-chain amino acid content, as well as antioxidant and anti-apoptotic properties.

Evaluation of haematinic activity of <i>Tapinanthus globiferus</i> (A. Rich.) van Tiegh leaf extract and fractions in phenylhydrazine-induced anaemic rats

Anaemia is a leading cause of morbidity and mortality in both males and females of all ages. Anaemia was induced by intraperitoneal (i.p.) administration of phenylhydrazine (60 mg/kg) for a period of 3 days. Anaemic rats were allotted to five (5) groups; group I served as the negative control, group II served as the positive control received Astyfer syrup (0.15 mg/kg p.o) , groups III-V served as the test groups that received Tapinanthus globiferus methanol extract, ethyl acetate and n-hexane fractions (100, 200 and 400 mg/kg, p.o.), respectively. Packed cell volume (PCV), haemoglobin concentration (HB) and red blood cell count (RBC) were analysed as indices of anaemia at 7-day intervals for 21 days. The mean cell volume (MCV) and mean cell haemoglobin concentration (MCHC) were calculated accordingly. Leaf extract and fractions of Tapinanthus globiferus significantly (P<0.001) increased the PCV, the HB concentration and the RBC, which had been originally decreased by phenylhydrazine (P<0.001) administration within one week of treatment. The extract and fractions were compared with rats administered with the positive and vehicle-treated group. The results suggested that Tapinanthus globiferus leaves have haematinicactivities.

Anti-anemic properties of Pterocarpus marsupium latex and its cytotoxic and embryotoxic effects.

Abstract Anemia is a hematological disorder, and a large number in the developing world are affected with significant morbidity and mortality. Among them, most depend on traditional medicine to strengthen the hematopoietic action. The availability, low cost, and minor side effects are thought to be associated with this high selection rate of traditional medicine. The Pterocarpus marsupium is a medicinal plant native to Sri Lanka, India, and Nepal. In which the different components are used by traditional medical practitioners in treating different disease conditions, specifically, latex in enhancing hemoglobin production in anemic patients. However, the scientific evidence for using the Pterocarpus marsupium latex as an anti-anemic agent is minimal. Therefore, this study is planned to evaluate its anti-anemic effect, erythropoietin (EPO)-like effect, toxicity, phytochemical composition, and bioactive ingredients. Consequently, we aim to apply in vitro and in vivo assays to investigate the toxicity and favorable anti-anemic and other hematopoietic potentials of the plant latex using normal human cell cultures, rat-derived hematopoietic stem cell cultures, zebrafish embryos, and phenyl hydrazine-induced anemic rats with identification of bioactive ingredients that might mediate such potentials. If we discover a similar action of EPO in this plant latex, it would be beneficial in the way of treating anemia-associated disease conditions such as chronic renal failure, myelodysplasia, rheumatoid arthritis, HIV, and cancer as a replacement for recombinant human EPO (rhEPO). This will be beneficial in the way of reducing the high cost of rhEPO treatment as well. Finally, an attempt to discover a therapeutic agent for anemia from a safe, natural source will considerably contribute to traditional medicine/herbalism due to the crucial role of traditional medicine in the prophylaxis or therapy of hematological diseases in Sri Lanka.

Hydrophilic extract of Pistacia vera pericarp protects against phenylhydrazine-induced hepatotoxicity and hemolytic anemia.

Pistacia vera is commonly used in traditional medicine to treat various disorders. This study aims to investigate the anti-anemia and hepatoprotective effects of Pistacia vera pericarp extract (PVPE) in a rat model of phenylhydrazine (PHZ)-induced anemia. PVPE was prepared using the maceration method. The extract was administered at doses of 20, 80, and 160 mg/kg for 28 days to normal and PHZ-treated rats. The effects of PVPE were evaluated in terms of changes in biochemical, histological, hematological, and molecular biomarkers in the liver and blood. Administration of PVPE to the anemic animals significantly restored these deleterious effects on hematological parameters compared to the anemic group. Kupffer cell activation was seen in the liver tissue of the anemic rats. Administration of PVPE mitigated these deleterious effects. PVPE has potent antioxidant activity and may represent a promising treatment for anemia and liver protection in clinical settings.

Pre-clinical protective potentials of Carica papaya constituents in experimentally induced anemia.

Anemia is a pathological condition characterized by reduced oxygen bioavailability and/or changes in hematological parameters. This study investigated the anti-anemic activities of Carica papaya (CP) phytoconstituents in aluminium-chloride-induced anemic rats. Twenty-seven rats were randomized into nine groups of three rats as follows; group 1 was the normal (non-induced) group, 2-9 were anemic rats administered 1 mL distilled water, standard drug (3 mg/kg body weight (bw) ferrous sulphate), 100, 300 and 500 mg/kg bw of crude methanolic extract of CP (CMECP) of the leaf and 100, 300 and 500 mg/kg bw of CMECP of the seed respectively in the first stage of the study. In the second stage, thirty-three rats were randomized into eleven groups of three rats as follows; group 1 was the normal group, 2-11 were anemic rats treated with 1 mL distilled water, standard drug, 75 mg/kg bw, 150 mg/kg of alkaloid fraction of CP seed, 75 mg/kg bw, 150 mg/kg bw of flavonoid fraction of CP seed, 75 mg/kg bw and 150 mg/kg of alkaloid fraction of CP leaf, 75 mg/kg bw and 150 mg/kg bw of flavonoid fraction of CP leaf respectively. Treatment of anemic rats with CP extracts and fractions of the seed and leaf significantly reversed the hematological parameters and body weight of anemic rats in a dose independent fashion. The CMECP leaf at 100 and 500 mg/kg gave PCV of 42.50±0.50 and 47.00±0.50, while the seed gave 49.50±0.50 and 42.50±0.50 respectively after 2 weeks of treatment. However, the alkaloid and flavonoid fraction of CP presented better anti-anemic properties probably due to constituents' synergism. This study concluded that CP possesses phytoconstituents which potentiates it as a safe anti-anemic drug candidate.

Hematopoietic effect of echinochrome on phenylhydrazine-induced hemolytic anemia in rats

Background Hemolytic anemia (HA) is a serious health condition resulting from reduced erythrocytes’ average life span. Echinochrome (Ech) is a dark-red pigment found in shells and spines of sea urchins. Aim Studying the potential therapeutic effect of Ech on phenylhydrazine (PHZ)-induced HA in rats. Methods Eighteen rats were divided into three groups (n = 6): the control group, the phenylhydrazine-induced HA group and the Ech group, injected intraperitoneally with PHZ and supplemented with oral Ech daily for 6 days. Results Ech resulted in a considerable increase in RBCs, WBCs, and platelets counts, hemoglobin, reduced glutathione, catalase, and glutathione-S-transferase levels, and a significant decrease in aspartate & alanine aminotransferases, alkaline phosphatase, gamma-glutamyl transferase, bilirubin, creatinine, urea, urate, malondialdehyde & nitric oxide levels in anemic rats. Histopathological examination of liver and kidney tissue samples showed marked improvement. Conclusion Ech ameliorated phenylhydrazine-induced HA with a hepatorenal protective effect owing to its anti-inflammatory and antioxidant properties.

Determination of the Effect of Oral Dosage of Labna Product Supplemented with Fe3O4 Conjugated with Chitosan Nanoparticles on Growth Parameters, Liver and Kidney Parameters in Anaemic Rats Induced by Phenylhydrazine

The research aims to investigate the effect of Fe3O4-NPs and its conjugated with chitosan nanoparticles on the rat’s body weights, liver enzymes, and the kidney function parameters in the serum of male albino rats induced with anaemia by phenyl-hydrazine. The rats were separated into six groups in five replicates, each of which included (T1) the control group, (T2) anaemia induced group, T3 group animals given Labneh enrichment with 2.5 mg of Fe3O4-NPs ml/day, T4 group animals given Labneh enrichment with 2.5 mg of Ch-NPs ml/day, T5 group animals given Labneh enrichment with 2.5 mg of each Fe3O4-NPs conjugated with Ch-NPs ml/day, T6 group animals given Labneh enrichment with 2.5 mg of Hamvir ml/day, and were fed for 30 days. The results showed a significant decrease (p≤0.05) in the Rat body weight gains of the anaemia-induced Rats group T2 (-1g) compared with the T1 group (22g). The liver enzyme concentration of AST, ALT and ALP was seen as a significant increase in the anaemia group T2 and became at 57.0, 62.6 and 82.0 compared to the T1 group at 38.3, 47.0 and 63.6 (IU/L) respectively. Also, the Creatinine and Urea of kidney function parameters were increased to 2.85 and 62.0 compared to the T1 group at 0.89 and 38.3 mg/dl respectively. The results of the oral dose of rats treatment groups T3, T4, and T5 and the treatment by drug Hamvir T6 were shown to significantly ameliorate the parameters of body weights, liver enzymes AST, ALT, ALP and kidney parameters of Creatinine and Urea parameters to its becomes at the values near of its in T1 value.

Oral Zinc-Rich Oyster Supplementation Corrects Anemia in Rats

This study investigates the impact of various zinc supplementation methods on anemia in rats induced by phenylhydrazine (PHZ) and in 5/6-nephrectomized anemic rats. We compare oral zinc sulfate (ZnSO4) supplementation, oyster Crassostrea gigas supplementation, and hard clam Meretrix lusoria supplementation on red blood cell (RBC) levels. Oral zinc-rich oyster supplementation (2.70 mg Zn (30 g oyster)/day/rat) effectively corrects anemia in both experimental groups. Rats orally fed oysters for four days exhibit similar effectiveness as those receiving a single ZnSO4 injection (0.95 mg Zn (4.18 mg ZnSO4⋅7H2O)/rat). In contrast, oral ZnSO4 supplementation (2.70 mg Zn (11.88 mg ZnSO4⋅7H2O)/day/rat) does not significantly increase RBC levels, suggesting better zinc absorption from oysters. A placebo group of anemic rats supplemented with hard clams, similar in composition to oysters but much lower in zinc, did not change RBC counts. This supports oysters’ high zinc content as the key to correcting anemia. Oysters also contain high iron levels, offering a potential solution for iron-deficiency anemia while supporting bone marrow erythropoiesis. In summary, oral oyster supplementation emerges as an effective strategy to correct anemia in rats with added zinc and iron support for erythropoiesis.

Embryonic Ectoderm Development (EED) Inhibitor APG5918 Improves Chronic Kidney Disease- (CKD)-Induced Hemoglobin Insufficiency in Preclinical Models of Anemia

Introduction Anemia can be caused by infections, malignancies, CKD, or chemotherapy. Increasing Hb or fetal hemoglobin (HbF) can prevent or reduce anemia-related pathophysiology. Polycomb inhibitory complex 2 (PRC2), consisting of EZH2, EED, and SUZ12, is a subunit of the major transcriptional corepressor complex of BCL11A, and targeting EED may be one novel approach for treatment of patients with anemia. We report the effects of APG-5918, a small-molecule selective EED inhibitor, on Hb and HbF induction in human CD34⁺ hematopoietic stem cells (HSCs) and the efficacy of APG-5918 in a CKD-induced anemia model in vivo. Methods The pharmacodynamic (PD) effects of APG-5918 were evaluated in human cord blood CD34⁺ HSCs by flow cytometry, RT-qPCR, and ELISA. In vivo, the antianemia effect of APG-5918 was evaluated in adenine-induced renal anemic Sprague-Dawley rats. Results APG-5918 inhibited H3K27me3 inCD34⁺ HSCs, the critical epigenetic mark catalyzed by PRC2. APG-5918 also increased γ-globin coding gene ( HBG) and β-globin coding gene ( HBB) mRNA levels in a dose-dependent manner. After 7 days of treatment with APG-5918 at 1 μM, HBG and HBB mRNA increased to 12.36-fold and 4.76-fold of the control group, respectively, which was pharmacologically superior to effects observed with hydroxyurea at 33 µM (~6.53-fold and 2.27-fold increases in HBG and HBB mRNA, respectively). Hb and HbF protein were also upregulated in a dose-dependent manner. A total of 1.69-fold and 1.9-fold increases in HbF and Hb protein expression were observed after 7 days of treatment with APG-5918 at 1 μM.HbF and Hb protein showed no significant difference after hydroxyurea treatment. In an adenine-induced renal anemic rat model, APG-5918 was administered orally once daily at 3 dose levels (5, 15, and 45 mg/kg). Both body weight and the blood parameters erythrocytes, Hb, hematocrit (HCT), and reticulocytes (RET) improved significantly in a dose-dependent manner compared to the model (adenine) group ( p < 0.05, 0.01, or 0.001) (Figure 1). APG-5918 showed similar in vivo efficacy with erythropoietin (EPO): body weight and blood parameters in the group treated with APG-5918 45 mg/kg were comparable to those in the EPO group. In addition, blood parameters in the APG-5918 (15 mg/kg) plus EPO group recovered to the level of the control group, which was superior to the APG-5918 and EPO monotherapy groups. Conclusions APG-5918 demonstrated its effects as a single agent on inhibition of H3K27me3 inCD34⁺ HSCs, HbF and Hb induction, and normalization of hematologic parameters in a CKD-induced anemia model. APG-5918 also showed synergistic antianemia effects when combined with EPO. These findings support APG-5918 as a novel treatment option for CKD-induced anemia.

Kigelia africana improves libido in phenyl hydrazine induced anaemic female Wistar rats

Background and Objective: Anaemia is a global public health challenge affecting adolescent girls, women of reproductive age, pregnant women and children in low and middle income countries. This study therefore was designed to evaluate the effect of extract of Kigelia africana on female sexual hormones following phenyl hydrazine induced anaemia. Materials and Methods: This research work was carried out using twenty five (25) female Wistar rats. The experimental rats were randomly divided into five (5) groups, with five animals per group .Group A served as Normal control (non-anaemic control), group B: Anaemic control(induced with phenyhdrazine) without treatment ,group C; anaemic rats treated with feroton (Standard control), group D; Anaemic rats co-administered with 200mg/kg petroleum ether leaf extract Kigelia africana extract (PETLETKG1), and group E; Anaemic rats treated with 200mg/kg between petroleum ether leaf extract Kigelia africana extract (PETLETKG2) .All administrations were done orally using oropharyngeal cannula once per day for 14 days (2 week). Blood was collected by cardiac puncture using disposable syringe and needle to draw blood into plane sterile tubes. Thereafter, the samples were analyzed using standard methods. Results: The result depicts the significant (p<0.05) increase in serum follicle stimulating hormone, prolactin, progesterone, oestrogen when compared with both normal and standard control. More so, the petroleum ether extract of K. africana showed no significant (P<0.05) difference on L.H hormone when compared with both the standard and the normal control. Contrastingly, the extract of K. africana decreases serum testosterone significantly (P<0.05) when compared with both the standard and normal control. Conclusion: The result suggests that the extract might be useful in improving the sexual health and libido of female animals following phenyl hydrazine induced anaemia.

Haematinic and Hepatoprotective Properties of Telfairia occidentalis Fruit Mesocarp on Phenylhydrazine-Induced Anaemia in Experimental Rats.

The level and potential of iron contained in fluted pumpkin (Telfairia occidentalis) has been exploited as a blood tonic; however, the potentials of some other parts of the plant are unknown. The effect of T. occidentalis fruit mesocarp (aqueous extract) on phenylhydrazine (PHZ)-induced anaemia in experimental rats was investigated in a bid to determine its curative properties and potential in reversing haemolytic anaemia and protection of liver health. The LD50 of the fruit extract was determined using Lorke's method for the determination of acute toxicity. The study involved oral administration of varying doses of the extract to different groups of rats which were monitored for 24 hours. The test sample did not show any signs of toxicity at doses of 5000 mg/kg b.wt, which is the highest possible recommended dose for toxicity testing. For the evaluation of the effects of the fruit extract on haematological indices and biochemical enzyme markers in anaemic rats, 30 matured albino Wistar rats were used. The rats were divided into five groups of six rats each. Group 1 consisted of normal rats (control group), Group 2 consisted of anaemic untreated rats, and Group 3 consisted of anaemic rats treated with the standard drug Astymin, while Groups 4 and 5 were made up of anaemic rats given the extract at doses of 600 mg/kg b.wt and 1000 mg/kg b.wt, respectively. The fruit extract failed to show any significant effect in improving the haemoglobin (Hb), alanine aminotransferase (ALT), aspartate aminotransferase (AST), and alkaline phosphate (ALP) levels in anaemic rats but rather may have contributed to a reduction in Hb levels and an unhealthy increase in serum enzyme levels. This is indicative of the apparent inability of the aqueous extract of the T. occidentalis fruit mesocarp to reverse PHZ-induced haemolytic anaemia and may suggest a possible detrimental effect of high doses of the extract over a prolonged period.

Determining the Effect of Fe3O4 Conjugated with Chitosan Nanoparticles on Labneh Product Characteristics and its Effect on Blood Picture Parameters in Anemic Rats Induced by Phenylhydrazine

The research aims to investigate the effect of Fe3O4-NPs and it's conjugated with chitosan nanoparticles on the immunological indicators, such as IgA, IgG, and interleukin-6, and the iron indicators, of Ferritin, Transferrin, TIBC, and Iron in the serum of male albino rats induced with anemia by phenyl-hydrazine. The rats were separated into six groups in five replicates, each of which included (T1) the control group, (T2) anemia induced group, T3 group animals given Labneh enrichment with 2.5 mg of Fe3O4-NPs ml/day, T4 group animals given Labneh enrichment with 2.5 mg of Ch-NPs ml/day, T5 group animals given Labneh enrichment with 2.5 mg of each Fe3O4-NPs conjugated with Ch-NPs ml/day, T6 group animals given Labneh enrichment with 2.5 mg of Hamvir ml/day, and were fed for 30 days. The results showed a change and increase in the values of free fatty acids, as they reached their highest value after 20 days of preservation, where the treatment (T1) recorded a noticeable increase, reaching (2.31). Likewise, in the treatment (T5), we notice a significant increase in it, as it reached (0.75), in contrast to the rest. All coefficients that were (T2), (T3) and (T4) recorded (0.53), (0.58) and (0.63), respectively. the values of RBCs and Hb, which gave a significant decrease and it was at 2.84 (1×106/ ml) and 6.4 (g/dl), respectively, compared to the control treatment (T1).

The Role of Extracellular Signal-Regulated Kinase Pathways in Different Models of Cardiac Hypertrophy in Rats.

Cardiac hypertrophy develops following different triggers of pressure or volume overload. In several previous studies, different hypertrophy types were demonstrated following alterations in extracellular signal-regulated kinase (ERK) pathway activation. In the current study, we studied two types of cardiac hypertrophy models in rats: eccentric and concentric hypertrophy. For the eccentric hypertrophy model, iron deficiency anemia caused by a low-iron diet was implemented, while surgical aortic constriction was used to induce aortic stenosis (AS) and concentric cardiac hypertrophy. The hearts were evaluated using echocardiography, histological sections, and scanning electron microscopy. The expression of ERK1/2 was analyzed using Western blot. During the study period, anemic rats developed eccentric hypertrophy characterized by an enlarged left ventricle (LV) cavity cross-sectional area (CSA) (59.9 ± 5.1 mm2 vs. 47 ± 8.1 mm2, p = 0.002), thinner septum (2.1 ± 0.3 mm vs. 2.5 ± 0.2 mm, p < 0.05), and reduced left ventricular ejection fraction (LVEF) (52.6% + 4.7 vs. 60.3% + 2.8, p < 0.05). Rats with AS developed concentric hypertrophy with a thicker septum (2.8 ± 0.6 vs. 2.4 ± 0.1 p < 0.05), increased LV muscle cross-sectional area (79.5 ± 9.33 mm2 vs. 57.9 ± 5.0 mm2, p < 0.001), and increased LVEF (70.3% + 2.8 vs. 60.0% + 2.1, p < 0.05). ERK1/2 expression decreased in the anemic rats and increased in the rats with AS. Nevertheless, the p-ERK and the p-MEK did not change significantly in all the examined models. We concluded that ERK1/2 expression was altered by the type of hypertrophy and the change in LVEF.

#5517 IN CHRONIC KIDNEY DISEASE, IRON DEFICIENCY-INDUCED ANEMIA IS ASSOCIATED WITH HIGHER LEVELS OF FGF23 THAT ARE NOT REDUCED BY IRON ADMINISTRATION

Abstract Background and Aims Iron (Fe) deficiency significantly contributes to anemia in chronic kidney disease (CKD). High FGF23 levels, commonly found in CKD, are related to adverse outcomes in patients. In the normal setting, an association between Fe deficiency and FGF23 has been observed. However, it is unknown whether Fe deficiency-induced anemia might contribute to the excessive FGF23 levels in CKD. Thus, this study was intended to evaluate the interplay between Fe deficiency, CKD, and FGF23. Method Male Wistar rats with normal renal function received either standard (40 ppm Fe) or Fe-deficient (4 ppm Fe) diets for 6 weeks to induce anemia. Then, several normal and all the anemic rats were switched to an adenine-enriched (0.6%) diet to induce renal damage. Groups of anemic-uremic animals were treated with oral (ferric citrate, FC and ferrous sulfate, FS) or intravenous (ferric carboxymaltose, FCx) Fe at a dose of 9 mg/kg for 5 weeks. Hematological and mineral metabolism parameters were determined at sacrifice. All experimental protocols were approved by the Ethics Committee for Animal Research of the University of Córdoba. Results Plasma and serum biochemistries are shown in Table 1. CKD per se was associated with derangements in hematological parameters. The presence of Fe deficiency-induced anemia further decreased these parameters, being statistically significant in the case of serum Fe (P = 0.003). Iron therapy improved hematocrit, hemoglobin, and Fe levels, although statistical significance for all of them was only reached when FC was administered (P = 0.012, P = 0.038, and P = 0.002, respectively). As expected, CKD rats exhibited disturbances in mineral metabolism. Interestingly, uremic and anemic rats showed higher intact (P = 0.039) and c-terminal (P = 0.048) FGF23 levels when compared with CKD group. Despite normalization of serum Fe, intact FGF23 further increased following administration of FS (P = 0.022), and same trend was observed with all the compounds. However, cFGF23 levels remained unchanged in all the Fe-treated groups. Conclusion The presence of Fe-induced anemia in an experimental model of CKD is associated with further increases in the levels of both intact and c-terminal FGF23. Thus, other factors distinct than serum Fe might influence FGF23 levels. Our results support the need for investigating the precise mechanisms underlying the relationship between Fe and FGF23 to optimize the clinical management of anemia, particularly in the context of renal dysfunction.
