Study of Toxicology Effects of Herbicide Paraquat on Heamatological Parameters of <i>Mesopotamichthys sharpeyi</i>

Pesticides are environmental contaminants that after use in agriculture, aquatic ecosystems are entered. These contaminants can enter the food chain and can cause problems for aquatic organisms and even humans. During the acute toxicity of this herbicide paraquat on some blood parameters, Mesopotamichthys sharpeyi (the total number of red blood cells, hemoglobin concentration, and total white blood cell count, hematocrit and blood indices) in fisheries laboratories, Khorramshahr University of Marine Science and Technology were studied. The sub lethal toxicity studies of 40 fish in 4 treated on the basis of three different treatments LC50 96 h (25, 50 and 75 percent LC50 96 h), and a control treatment for 96 hours were exposed to the pesticides paraquat. 10 fish were randomly distributed into plastic containers 25 liters. Tests based on standard methods O.E.C.D were on the fish and the static. The number of red blood cells, hemoglobin concentration, percent hematocrit, white blood cell count, MCV, MCH and MCHC Mesopotamichthys sharpeyi at different concentrations after 96 h with the control treatment significantly reduced (0.05 > P) that was directly affected by different concentrations of the paraquat.

Haematological Profile of Pregnant Women Attending Antenatal Clinic in Bauchi, Nigeria

Introduction: Haematological profile of pregnant women provides vital information on physiological changes in pregnancy progress, outcome and possible maternal-foetal complications. The study assessed the haematological profile of pregnant women attending the antenatal clinic. Methodology: The cross-sectional study was conducted at the antenatal clinic of Abubakar Tafawa Balewa Teaching Hospital, Bauchi between July and September 2018 among pregnant women attending the antenatal clinic. Study participant was recruited on voluntary basis and study questionnaire and informed consent administered. Blood samples are collected and analysed using System x haematology autoanalyser. Result: A total of 191 study participants comprised of 141 pregnant women at different trimester stages and 50 non-pregnant. Mean haematocrit, haemgloblin, white blood count and platelet count of 35.8 ± 9.0, 11.6 ± 1.6, 7.7 ± 5.7, and 234.0 ± 74.6 respectively. Significant difference was observed between pregnant and non-pregnant women in neutrophil (0.016), mixed (eosinophil, basophil and monocyte, 0.05), lymphocyte (0.000), platelets (0.002) and RDWSD (0.025). Comparing haematological profile with trimester stages, significant association was observed with white blood cells count and mixed cell counts. Conclusion: The reduction in mean white blood cells count and increased haemocrit concentration with the trimester stages contradict patterns in other similar studies. This further highlights the need for local data for early diagnosis of pregnancy-associated clinical conditions and management approach.
