It can lead to cardiovascular disease and functional disturbances including haematological parameters. Full blood count (FBC) parameters of a total of 60 consecutively-recruited hypertensive subjects and 30 age-matched non-hypertensive controls were studied between June and September, 2018. Ethylene Diamine Tetra Acetic Acid (EDTA) anticoagulated blood and serum from subjects and control participants were analyzed for FBC. The total white cell count (WBC), packed cell volume (PCV) haemoglobin (Hb), neutrophils and eosinophils were significantly lower among hypertensive subjects compared to non-hypertensive controls (p 40-year-old compared to those <40 years of age (p = 0.02 and 0.01) respectively. The RBC count was significantly higher among female compared to male hypertensives (p = 0.05). The haemoglobin and monocyte count were significantly higher among male compared to female hypertensives (p = 0.02 and 0.04) respectively. The monocyte count was significantly higher among hypertensive subjects of Hausa ethnic group compared to Fulani (t = 2.79, p < 0.01). The findings from this study indicates that the WBC, PCV, Hb, neutrophils and eosinophils were significantly lower among hypertensive subjects compared to non-hypertensive controls. Stage of the disease, age, gender and ethnicity had a significant effect on the FBC parameters of the hypertensive patients. There is need to step up public enlightenment programme to educate hypertensive patients on the need for attending clinic regularly for effective follow up. It is recommended that facilities for the routine monitoring of FBC parameters among hypertensive in the area be provided.展开更多

This gas has capacity to bind with haemoglobin to compete for oxygen uptake when inhaled, thereby altering the blood physiology. Aim: The aim of this study is to determine the effect of carbon monoxide on haematology and haemostasis parameters among the exposed workers at gasoline generators service centre in Benin City. Methodology: Eighty-eight participants (workers n = 44 and;controls n = 44) took part in this study. Carbon monoxide used for this study was sourced from the smoke being emitted by gasoline generators during repairs. The participants’ haematological parameters were analysed using haematology autoanalyzer (Sysmex Poch 100i model, Germany), while PT and PTTK were assayed using standard methods. Results: The mean values of red blood cells (RBC), white blood cells (WBC), platelets (PLT), haemoglobin concentration (Hb), hematocrit (HCT), mean cell volume (MCV), mean cell haemoglobin (MCH), mean cell hemoglobin concentration (MCHC) and red cell distribution width coefficient variation (RDW-CV) observed in both the workers at generator service center and their controls fell within normal ranges, but the mean red cell distribution width standard deviation (RDW-SD) of workers at generator service center fell below normal as against the normal value for controls. There were no significant differences in serum concentrations of lymphocytes (p = 0.134), and granulocytes (p = 0.584). In contrast, significantly (p Conclusion: In this study, carbon monoxide emitted during repairs has no deleterious effects on haematological and haemostasis parameters of the exposed workers at generator service centre in Benin City. However, PT and PTT exceeded normal value in the workers at the generator service centre compared to the controls. More work needs to be done especially on longer duration of exposure and at various concentrations of carbon monoxide exposure.展开更多
