ABSTRACT
Aim: The effect of Solanum aethiopicum (SA) on the haematological indices of Wistar rats was investigated in this study. Methodology: A total of 20 male Wistar rats with an average 172.45±0.15 g were distributed into four groups (A – D) and allowed to acclimatize for two weeks. Group A served as the control, while groups B, C, and D were given aqueous extracts of SA at doses of 75 mg/kg, 150 mg/kg, and 225 mg/kg per body weight, respectively, every 48 hours for 30 days. After the exposure period, a final evaluation and sacrifice of the rats was performed. Blood sample collection was carried for full blood count and blood film preparation. Results: The result of this study showed that leaf extract of Solanum aethiopicum caused a significant increase in white blood cells (18.18±0.78 - 27.08±2.68 x 103/?l), especially lymphocytes (13.58±2.48 - 30.95±4.65 x 103/?l) in group of rats when compared to control. On the contrary, there was a non-significant reduction in red blood cells (7.78±0.04 - 7.19±0.45 x 106/?l), hemoglobin (16.92±0.62 - 14.55±0.95 g/dl), haematocrit (41.49±0.29 - 38.38±1.68 %), mean corpuscular hemoglobin (21.71±0.91 - 20.30±0.10 ?g) when compared to the control. Platelet (451.25±87.25 - 724.75±249.25 x 103/?l) and Plateletcrit (0.36±0.07 - 0.50±0.17 %) was significantly higher in treated group, while mean platelet volume (8.21±0.31 - 6.98±0.07 ?m3) and platelet distribution width (18.68±1.38 - 15.93±0.73 %) was low when compared with control. Conclusion: The current study has demonstrated that the leaves of Solanum aethiopicum may be safe to consume in regulated amount, as it has been shown to boost blood indices. These plant extracts may be utilized as a blood promoting potentials as it has been shown to strengthens the body's immune system particularly cell-mediated immunity, have no hemotoxic impact on the red blood cell and its indices and improve the ability for the body to repair itself as seen from the platelet count and its indices.
ABSTRACT
Background:Schistosomiasisand Malaria are among the most prevalent afflictions of humans who live in areas of poverty in the developing world. The present study was aimed at determining the socio demographic characteristics and prevalence of schistosomiasis and malaria in childrenliving in Suburb of Malentouen Health District and analyzing the effect of co-infection on haemoglobin level, mean corpuscular volume and platelet count. Methods:Questionnaires were distributed to parents or guardians of children attending public primaryschool in the area. A total of 429 pupils aged 6-15 years old were screened for urinary schistosomiasis and 228 out of the 429 were tested for. Prevalences of thetwo parasites were calculated; Haemoglobin level, Mean Corpuscular Volume and platelets count of the 228 participants were recorded.Results:The prevalence of malaria was 26.75%, where as that of schistosomiasis was 43.82%. 31(13.60%) of the participants were co-infected with the two parasites. Mean haemoglobin level obtained was 11.01± 1.19 G/dL, that of MCV was 84.50±5.31/fl and the mean platelet count was 255.13±96.99/μl. In malaria single infected and co-infected participants, low haemoglobin level (2= 50.315, p = .000), low MCV (2= 27.448, p = .000) and low platelets count (2= 37.253, p = .000)were observed with significant variations.Conclusions:The three haematological parameters analysed in this study (Hb, MCV, Platelets count), showed low level or amount in malaria and malaria-schistosomiasis infected participants. Moreover, thrombocytopenia in children in this endemic area may be useful as supportive diagnostic criteria for malaria in case with low level of parasite number
ABSTRACT
@#Haematological cellular structures may be elucidated using automated full blood count (FBC) analysers such as Unicel DxH 800 via cell population data (CPD) analysis. The CPD values are generated by calculating volume, conductivity, and five types of scatter angles of individual cells which would form clusters or populations. This study considered 126 CPD parameter values of 1077 healthy Malaysian adults to develop reference intervals for each CPD parameter. The utility of the CPD reference interval established may range from understanding the normal haematological cellular structures to analysis of distinct cellular features related to the development of haematological disorders and malignancies.
