Catfish is a traditional part of the diet of a large section of the world’s population. This study compared the effect of smoked and oven-dried catfish on hematological parameters, liver and antioxidant enzymes of wistar rats. Catfish samples were processed by smoking and oven-drying and used for formulation of the experimental feeds. Twenty one wistar rats were acclimatized for seven (7) days, weighed and allotted into three dietary treatments; control (standard feed), smoked and oven-dried fed groups. The study was conducted for a period of 21 days. Haematological analysis was carried out using haematology auto-analyzer. Liver enzymes (Alanine aminotransferase (ALT), Aspartate aminotransferase(AST), alkaline phosphatase (ALP) and Gamma-glutamyltransferase (GGT)) were assayed using standard assay kits while antioxidant enzymes were assayed using spectrophotometric method. The result revealed a significant increase (P<0.05) in the body weights of rats maintained on experimental feeds; oven-dried catfish fed group (240.83±6.13g), smoked catfish fed group (246.83±4.97g). There were no significant difference (P>0.05) in the haematological parameters of the treatment groups except in their total red blood cell counts, mean cell volume and mean cell hemoglobin. A non-significant difference (p>0.05) was observed in the antioxidant enzymes (SOD and CAT) of the test groups, indicating the absence of oxidative stress. The results of this research showed that both drying methods (oven and smoke drying) did not affect the palatability of the diets as the experimental diets were accepted by the experimental animals and their weight significantly improved. However, both diets have deleterious effects on the blood; hence, individuals with severe cases of anaemia and other blood disorders are encouraged to avoid them.

ABSTRACT Objective: The objective was to determine the basic hematological parameters of remunerated blood donors in Benin City and to compare them with those of voluntary donors. Materials and Methods: This is a prospective study conducted in a tertiary health facility in Benin City. Pretransfusion samples were obtained from blood bags after gentle mixing and analyzed for hematological parameters. Samples were analyzed using the hematology autoanalyzer MODEL SYSMEX KN21. Result: A total of 215 samples were obtained comprising 160 remunerated (paid) and 55 voluntary donor samples. In the paid donors, the mean hemoglobin concentration (Hb) and hematocrit (HCT) 7.7±2.9 and 28.8±8.5 respectively. This was significantly lower than those of voluntary donors who had 13.9±1.2 and 42.2±3.3 with P < 0.001. The mean values of the red cell counts (RBC), white cell counts (WBC), mean cell volume (MCV), mean corpuscular hemoglobin (MCH), and mean corpuscular hemoglobin concentration (MCHC) were significantly lower in paid donors as P-values were <0.001. MCV was significantly low but not compared to the other parameters as P=0.04. There was no significant difference in the platelet count. Conclusion: Paid donors in Benin City have significantly lower hematological parameters than controls.

Ethanol Extracts

This study was designed to investigate the effects of the different extracts of Chromolaena odorata leave on the hematopoietic system of Wistar rats. Solvent extraction was used for the ethanol and aqueous extractions while decoction method was used for the crude extraction. Fifty Wistar rats of both sexes weighing 140-180 g were used for this study. They were divided into ten groups each containing five rats. The animals were fed the extracts by oral gavage once daily for 21 days. Blood sample was collected via cardiac artery. Hematological parameters were analyzed using automation method. The ethanol extract gave the highest extract yield. The aqueous, ethanol and crude extraction had median lethal toxicity (LD50) of 2738.6 mg/kg, 1581.1 mg/kg and 224.7 mg/kg, respectively. Significant difference (P<0.05) in the total white blood cell count was observed in the 75 mg/kg ethanol and 300 mg/kg crude extracts when compared with control group. Significant difference (P<0.05) in the hemoglobin concentration was observed in the 150 mg/kg ethanol extracts when compared with the control group. Significant difference (P<0.05) in the packed cell volume was seen in the 75 mg/kg aqueous, 150 mg/kg aqueous and 75 mg/kg ethanol extracts in respect to the control group. The mean cell volume, the mean platelet volume and platelet large cell ratio of the 75 mg/kg aqueous extract were significantly different (P<0.05) when compared with the control group. The present study showed possible treatment-induced hematopoietic function of C. odorata leave extracts.

Age Related Changes

Different studies proved that exposure over prolonged periods to pesticides increase the likelihood of developing adverse effects. 2,2-dichlorovinyl dimethyl phosphate (DDVP) is a predominant pesticide used in controlling insects. Therefore this study was aimed to investigate the age related changes in hematological indices of animals exposed to DDVP. Thirty healthy male Wistar rats were used in this study. Animals were grouped into three major groups of ten animals each. Group one animals served as young group (5 - 6 weeks) while group two and three was the middle-aged (2 months) and old groups (3-4 months) respectively. All the groups were subdivided into control and DDVP group with five animals in each subgroup. The DDVP groups were exposed to DDVP for five weeks. At the end of fifth week, they were euthanized with blood collected through cardiac puncture, hematological indices were analysed with autohematological analyzer.Exposure to DDVP significantly increased white blood cell counts and basophiles in old group. Platelets count and plateletcrit (PCT) were significantly decreased in young animals that were exposed to DDVP while platelet distribution width (PDW) and Mean platelets volume (MPV) were not significantly different across the groups. Red blood cells count, Hematocrit, Hemoglobin concentration, Mean cell volume, Mean cell hemoglobin and Mean cell hemoglobin concentration also show no significant difference across groups. Exposure of Wistar rats to Dichlorvos has no impact on haematological parameters in middle agerats. However, dichlorvos affects young and old animals proving age dependent effect of DDVP on hematological parameters. Keywords: DDVP, hematology, white blood cells, platelet, age

Clarias gariepinus were collected from Lake Chivero, Zimbabwe, and examined for nematode parasites from November 2000 to May 2002. Of the 202 specimens collected, 42.6 % were infected with third-stage larvae of Contracaecum sp. in the body cavity. The intensity of the infection was 1-7 worms per fish (mean intensity = 2.2). Seasonal variation in the prevalence of the parasite was not obvious and there was no significant difference in the prevalence of infection between males and females (c2 = 2.228; P > 0.05). No significant relationship between host size and prevalence was established. There was also no significant relationship between intensity and the body condition factor (r = 0.11; P > 0.05). The low parasite prevalence may have been caused by the disruption of the infection cycle since piscivorous birds, which are the final hosts of the parasite, do not feed on C. gariepinus in Lake Chivero.

Hamidi BL, Samigun, Lestari A. 2010. The effect of extract ethanol of pegagan (Centella asiatica) on the performance of Wistar rats after restraint stress. Biofarmasi 8: 11-16. The aim of this research was to investigate the effects of extract ethanol of pegagan (Centella asiatica) after treated with restraint stress by measuring the eight arms radial maze performance of rats. Pre-test and post-test controlled groups design was applied in this research. Male Wistar rats (Rattus novergicus) with the mean age of 8 weeks and the body weight of 150-200 grams which used for sample were divided randomly into 4 groups, each group consisted of 6 rats, i.e. (i) control group (without any treatment), (ii) stress group (it was given by restraint stress for 2 hours/day for each rat), (iii) pegagan group (it was given by 0.3 mg/g BW/day/rat extract ethanol of pegagan), and (iv) pegagan and stress group (it was given by 0.3 mg/g BW/day/rat extract ethanol of pegagan and restraint stress for 2 hours/day for each rat). The treatments were given for 21 days. Within 12 days for each pre-treatment and post-treatment, a test on the eight arm radial maze was conducted on individual rat to observe its performance. The assessment of rat performance in the eight arms radial maze test was conducted based on error type B. Kruskal-Wallis and Mann-Whitney tests with SPSS for Windows 16 version were applied to analyze statistically the difference between four groups. Kruskal-Wallis test was used to show the significant performance level difference between four groups of rats with p=0.001, while Mann-Whitney test was used to determine the significant difference between stress group and pegagan group (p=0.001), also stress group and pegagan and stress group (p=0.001). The result of research showed that there was no significant difference between control group and stress group (p=0.051), control group and pegagan group (p=0.143), control group and pegagan and stress group (p=0.143), also pegagan group and pegagan and stress group (p=0.952). It was concluded that extract ethanol of pegagan improved the performances of rats on the eight arms radial maze after treated with restraint stress.

Background. Herbal medication is a worldwide and ancient practice, mostly in developing countries, where a large part of the population is involved in this practice. Hence, studies must be conducted to evaluate their safety and efficiency to avoid or prevent toxicological risks due to their usage. In Togo, Carissa spinarum is a medicinal plant belonging to Apocynaceae family, used as an aphrodisiac or to heal some ailments including malaria, sickle cell anemia, hypertension, pain, and asthma. Notwithstanding its several ethnomedicinal benefits, just a few toxicological data associated with its chronic use are available. Objective. Therefore, this study aims to assess the toxicity of an ethanolic root extract of Carissa spinarum in Wistar rats. Methods. The 90-day oral toxicity process following OECD TG 408 guidelines is used. Male Wistar rats received Carissa spinarum root hydroethanolic extract at 500 and 1000 mg/kg for 90 days by oral gavage. Body weight changes, hematological and blood biochemical parameters, organ weight changes, malondialdehyde as a lipoperoxidation marker expressed according to tissue proteins, and histopathology of vital organs were assessed. Results. No signs of toxicity or mortality were observed during the 90 days experiment. Hematological parameters have not shown any treatment-related abnormalities. According to biochemical parameters, an increase in the chloride ion level was observed at 1000 mg/kg p < 0.01 . There was no significant difference between the treated groups and the control group concerning the malondialdehyde concentration, body weight, and organ relative weight. No changes in necropsy and histopathology of vital organs associated with extract treatment were observed. Conclusion. The results indicated that an ethanolic root extract of Carissa spinarum does not cause adverse effects, which can lead to Wistar rats’ death after 90-day oral administration at 500 and 1000 mg.

The main aim of study is to evaluate the anti-arthritic effect of different extracts of Boerhaavia diffusa in arthritic rats. Different extracts were prepared by successive solvent extraction methods by using the various polar and non polar solvents and their % yields were calculated. Arthritis was induced by FCA induced arthritis model in rats and paw volume was measured on different days. Body weights of all animals were also measured simultaneously and at the end of experiment some haematological parameters were measured. On preliminary phytochemical studies extracts showed the presence of alkaloids, fatty acids, terpenoids, flavonoids and phenolic compounds. Among all extracts, methanolic extract significantly decreased the paw volume in all treated groups. Methanolic extracts also restored the body weight significantly. The results of our study revealed that all the extracts treated group’s causes significant alterations in the hematological parameters and maximal effects were observed at 400 mg/kg. Since methanolic extract showed best activity in arthritic model and its phytochemical study showed presence of flavonoids and phenolic compounds, so it may be possible that anti-arthritic activity of root extracts may be due to presence flavonoids.  Keywords: Arthritis, FCA induced arthritis, Boerhaavia diffusa, haematological parameters, and Body weight

Background: A high prevalence of chromium and benzene compounds in the environment associated with motor vehicle and industrial operations arouses interest in the study of these xenobiotics in a long-term experiment. The objective of this work was to analyze effects of a chronic combined exposure to chromium and benzene on the hypothalamic-pituitary-adrenocortical (HPA) and immune systems of male Wistar rats. Materials and methods: Eighty male Wistar rats were administered potassium dichromate and benzene with drinking water in doses equaling one maximum permissible concentration (MPC) during 135 days. The hypothalamus, pituitary gland, adrenal glands, thymus, and spleen were then studied using morphometric, histological, and electron microscopy methods. The streptavidin-biotin peroxidase method was used to determine the expression of pro-apoptotic protein p53 and anti-apoptotic protein bcl2. We also measured the body, thymus and spleen weights of animals, nucleated cell counts in the thymus, spleen, and bone marrow and evaluated the cellular composition of the spleen and bone marrow as well as spontaneous and concanavalin A-induced secretion of interferon gamma (IFN-γ), IL-4, IL-6, and IL-10 cytokines by splenocytes. Results: We established an adverse effect of the exposure on the HPA function expressed in the activation of its secretory activity, blocking the release of hypothalamic neuropeptides at the level of the neurohypophysis and leading to ultrastructural damage to the neurosecretory cells of the hypothalamus, pituitary adenocytes and adrenal cortical cells, as well as in an increase in the programmed death of thymocytes. We also observed a decrease in the thymus weight and thymocyte counts and a complex of structural and functional changes indicating the status of its accidental involution in the exposed rats. The revealed decrease in the splenocyte count in the experimental group was accompanied by an increase in the size of the white spleen pulp. An increase in the induced production of the main immunoregulatory cytokines IFN-γ and IL-4 by splenocytes was found. Conclusion: Our findings can be used to analyze impairments of the HPA and immune systems in workers with a chronic combined exposure to benzene and chromium compounds in the occupational setting.

INTRODUCTION Patients with anaemia are commonly referred for bidirectional endoscopy. The aim of this study was to determine if any haematological parameters could predict positive findings at endoscopy. PATIENTS AND METHODS A total of 209 patients had bidirectional endoscopies performed for anaemia between September 2002 and March 2004. The endoscopy reports, histology and full blood count results (haemoglobin [Hb], red blood cells [RBCs], packed cell volume [PCV], mean cell volume [MCV] and mean cell haemoglobin [MCH]) were then reviewed. Statistical analysis was performed using non-parametric tests. RESULTS Overall, 197 patients had successful bidirectional endoscopies with 12 requiring completion barium enema. In 48 (23%) of these patients, a cause of anaemia was found with 15 (7.2%) carcinomas detected (2 upper GI and 13 lower GI). There was a significant difference in haemoglobin (9.2 g/dl versus 10.1 g/dl; P = 0.0044), RBCs (3.56 × 1012/l versus 3.83 × 1012/l; P = 0.0325) and PCV (0.279 l/l versus 0.31 l/l; P = 0.0112) between patients with positive findings at endoscopy and those with a normal investigation. Cancer patients had significantly lower haemoglobin (8.65 g/dl versus 10.1 g/dl; P = 0.0103), RBCs (3.45 × 1012/l versus 3.83 × 1012/l; P = 0.0179) and PCV (0.27 l/l versus 0.31 l/l; P = 0.0298) compared with patients with normal endoscopies. There was no significant difference in the other haematological parameters between those found to have positive findings and those that had normal endoscopies. CONCLUSIONS Based on this study, the yield of bidirectional endoscopy is low, with haemoglobin and PCV being the most useful haematological indices of significant pathology. Ferritin and MCV did not predict the likelihood of finding a gastrointestinal cause for the anaemia.
