The present study investigated the body weight and platelet count changes observed in zidovudine pre-administered Wistar albino rats on treatment with ethanolic extracts of the leaves Annona muricata (AM) and roots of Fagara zanthoxyloide (FZ). Plants samples were collected from Alakahia community, Rivers state and Opoo community, Ogun state; while Wistar albino rats were grouped into normal control, negative control (receiving zidovudine at 100 g/ml/Kg bw), AM and FZ extract treatment (at 4.5 and 3.8 g/ml/Kg B.W respectively) groups with analysis performed bi-weekly. All tests were performed using standard procedures with all reagents of analytic grade. Phytochemical screening of the extracts showed significantly high amounts of alkaloids (10.47- 21.15 mg / 100 g), phenols (10.60-15.22 mg / 100 g) and tannins (14.23 - 50.19 mg / 100 g). The investigation into their proximate compositions also showed high fat (5.78 ± 0.02) in FZ, moisture (10.47 ± 0.05) in AM and fibre (7.37 ± 0.03) in FZ. The amino acid phenylalanine (5.10-6.01 g / 100 g), isoleucine (4.44-5.20 g / 100 g), lysine (4.03 -5.31 g / 100 g) was observed to be available in the extracts. In the normal control group body weight increased by 20.75 g at week 6 while administration of Zidovudine, resulted in a decreased in bodyweight by 1.14 g in week 2 and 3.32 g in week 6. Extract treatment caused a significant increase (p≤0.05) in body weight by 17.95g (AM) and 18.23g (FZ) at week 6. Platelet count was also observed to significantly decrease (p≤0.05) by 33.42% in the negative control group when compared to the normal control. This was observed to significant increases in extract treatment by 49.56% (AM) and 51.32% (FZ). The results thus suggest a possible beneficial effect of the extracts of AM and FZ in checkmating the weight and platelet loss observed as a side effect of zidovudine therapy as well as the possible use in haemorrhagic conditions to reduce bleeding without thromboembolism.","PeriodicalId":13659,"journal":{"name":"International Blood Research & Reviews","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91132841","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Several epidemiological studies have reported that the distribution of different ABO blood groups vary markedly among the populations of different geographical areas reflecting racial differences. \u0000Aims: The aim of this study was to determine the association between ABO blood group and anthropometric indices among apparently healthy young adults of Yoruba ethnicity. \u0000Study Design: This is a cross-sectional descriptive study. \u0000Place and Duration of Study: The study was carried out at Department of Physiological Sciences and University Health Centre, Obafemi Awolowo University, Ile-Ife between May 2016 to June 2017. \u0000Methodology: Eighty apparently healthy young adults who were purposely selected participated in the study after screening for the ABO blood groups following the standard protocol. They were divided into four equal groups; 20 in each of blood groups A, B, AB and O who were age- and sex - matched. The weight (kg) and height (cm) of the participants were measured following standard protocol. Body mass index (BMI) and body surface area (BSA) were estimated from weight and height using Quetelex and Mosteller formulae respectively. Chi-square was used to compare grouped data while the comparison of means of parameters among the four blood groups was done using Analysis of Variance (ANOVA). A p-value of < 0.05 was taken statistically significant. \u0000Results: Out of the total 80 participants, 15% were males. The mean ± SD of height(m) of participants with blood groups A, B, O and AB were 1.65 ± 0.06, 1.63 ± 0.08, 1.62 ± 0.08 and 1.63 ± 0.08 (F= 0.349, p= 0.790) respectively. The mean ± SD of weight(kg) of the participants with blood group A,B, O and AB were 56.15 ± 8.71, 56.00 ± 11.21, 57.10 ± 12.73 and 58.05 ± 10.35 (F= 0.154, p= 0.927) respectively.

Von Willebrand factor (VWF) is an important marker of endothelial dysfunction. Plasminogen activator inhibitor-1 antigen (PAI-1-Ag), the major physiological inhibitor of tissue plasminogen activator (tPA), is mainly produced by endothelium. The aim of this study is to measure plasma levels of von Willebrand factor, Plasminogen activator inhibitor-1 antigen in type 2 diabetes mellitus patients and to correlate with glycated haemoglobin (HbA1c). \u0000Study Design: This prospective cohort study was conducted on 30 diagnosed type 2 DM patients who were about to start treatment. \u0000Place and Duration of Study: Medical outpatient (MOP) clinic of Enugu State University of Science and Technology Teaching Hospital (ESUTTH), between January and December 2016. \u0000Methodology: We included 30 patients (13 men, 17 women; age range 40-80 years) with type 2 diabetes mellitus. Blood samples were drawn from the patients before they commenced treatment, six months into the treatment and at twelve months of the treatment. Blood samples were also drawn from 25 age matched non diabetic patients. Plasma von Willebrand factor and Plasminogen activator inhibitor-1 antigen levels were determined by Enzyme linked immunosorbent assay. Glycated haemoglobin (HbA1c) and fasting blood sugar (FBS) levels were also evaluated along with them. \u0000Results: This study was conducted on 30 type 2 DM patients consisting of 13 males and 17 females. At treatment naïve, mean levels of vWF were significantly increased (45.48 +/- 6.46) in male type 2 Diabetic patients compared to the control (20.45 +/- 0.26). Six months into treatment mean levels of vWF were significantly increased (48.18 +/- 4.99) in female type 2 Diabetic patients compared to the control (37.64 +/- 7.93). The plasma levels of vWF were significantly and positively correlated with HbA1c at six months into treatment in male type 2 DM patients. The plasma levels of vWF were also significantly and positively correlated with PAI-1 at six and twelve months into treatment in both genders. \u0000Conclusion: There was strong significant positive correlation between plasma levels of vWF and PAI-1 in type 2 diabetes mellitus patients.","PeriodicalId":13659,"journal":{"name":"International Blood Research & Reviews","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-05-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82235753","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

An additional role for alterations in epigenetic mechanisms has been also highlighted in the pathogenesis of the disease. This may have a role in determining the disease outcome, impact the treatment decision and provide options for targeted therapies especially in patients who lack genetic aberrations. One of the modes of epigenetic dysregulation is mutation in genes encoding isocitrate dehydrogenase 1 and 2 that has been observed in AML with a higher incidence in patients with normal karyotype (NK). \u0000Aim of the work: The aim of this work was to study the frequency of IDH1 (R132) and IDH2 (R140Q, R172K) mutations in adult Egyptian patients with de novo acute myeloblastic leukemia (AML), their relation with clinical characteristics, other molecular markers (the internal tandem duplication (ITD)) mutation of FLT3 gene and NPM1 gene mutation) and impact on treatment outcome. \u0000Methods: Peripheral blood samples from 50 adult patients with denovo acute myeloid leukemia, admitted to the haematology unit at Alexandria Main University Hospital from February 2015 to February 2017, were used. The polymerase chain reaction-restriction fragment length polymorphism method (PCR-RFLP) was used for detection of IDH1 codon R132 and IDH2 codons (R140, R172) mutations on genomic DNA. PCR was used for detection of FLT3-ITD mutation on genomic DNA. PCR was used for detection of NPM1 mutation on RNA. \u0000Results: IDH 1and 2 mutations occurred in 30% of newly diagnosed AML patients and 47.6% of NK patients. Both mutations did not co-occur except in one case. IDH positive patients were significantly older than IDH negative patients (p=0.003). There was no statistically significant correlation between any of the clinical parameters and the IDH mutations. FAB-M2 was the most common FAB subtype among IDH positive patients. No correlation between IDH mutations and NPM1 or FLT3 could be demonstrated. IDH positive patients had significantly lower CR rates after induction chemotherapy than IDH negative patients (p=0.021). \u0000Conclusion: IDH1, 2 mutations are recurring genetic alterations in AML with a higher incidence in patients with normal karyotype and they may have an unfavorable impact on clinical outcome in adult AML patients.","PeriodicalId":13659,"journal":{"name":"International Blood Research & Reviews","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89869328","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Two hundred and twenty three (223) adult male and females (MSK traumatized) and fifty apparently healthy volunteers (adults) were ethically recruited from the National Orthopaedic Hospital, Enugu, regional centre for trauma, orthopaedic, burns and plastic surgery in south-east Nigeria. Using the Leishman’s stained blood smear technique, leucocyte profiles [Neutrophil, Lymphocytes, Basophils, Eosinophils and Monocyte counts] were obtained for each participant. In all case, Age, Gender and duration of hospitalization were also obtained. Following careful analysis, study found, using one way analysis of variance (ANOVA), a statistically significant increase (p < .05) in acutely traumatized subjects; with adults of ages 20 to 49 years constituting the majority (70%). A statistically significant lymphopenia was also observed in test population, with Pearson Product Moment Correlation proving positive for higher levels of WBC counts. A negative correlation was also seen for Neutrophils and lymphocyte counts, implicating the Neutrophil-Lymphocyte Stress Factor (NLSF).
