Malaria is a life-threatening disease and emergence of malaria parasite resistance to antimalarial drugs, has necessitated the need for discovery and development of an alternative to malaria medicine. This study assessed the ethanolic leaf extract of Eucalyptus citriodora for the presence of bioactive components qualitatively and efficacy of the extract against the malaria parasite. Standard methods were used to determine the bioactive components of the leaf extract. Twenty (20) albino mice of body weight between 18-25 g were randomised into 5 groups of four mice each for acute toxicity test, while twenty-four (24) mice were randomised into six groups of four mice each (group 1, 2, 3, 4, 5 and 6) for antiplasmodial activity. All the groups were infected with P. berghei, except group 3 (normal control). Group 4, 5 and 6 were treated with 0.2 mL of 200, 400 and 800 mg/kg body weight of extract respectively. Group 2 (positive control) were treated with 0.2 mL of 5 mg/kg body weight of chloroquine. Group 1 (negative control) were administered with 0.2 mL of normal saline, while group 3 (normal control) were administered with 0.2 mL of normal saline for four consecutive days. Phytochemical screening revealed the presence of alkaloids, saponins, tannins, anthraquinone, flavonoids and cardiac glycosides and the extract was found safe and nontoxic. The antiplasmodial investigation revealed a decrease in percentage parasitaemia level in mice of group 4, 5 and 6 (extract treated group) compared with mice of group 1 (infected and not treated). The parasitaemia reduction was higher in group 6 (800 mg/kg). This significant decrease (P<0.05) in percentage parasitaemia level in the study was dose and time-dependent. The study revealed the potency of E. citriodora leaf extract as a future herbal candidate for the treatment of human malaria infection.

The leaf, stem and bark of Eucalyptus citriodora are combined for use in the treatment of malaria in Anyigba, North Central, Nigeria. However, no scientific investigations have been carried out to know the effect of this plant on biochemical parameters of experimental mice. Thus, this study evaluated the biochemical parameters of mice infected with Plasmodium berghei after the administration of ethanolic leaf extract of E citriodora. Twenty-four (24) mice of body weights between 18-25 g were grouped into six groups. Group 1, infected but not treated (negative control), group 2, infected and administered with 0.2 mg/kg of chloroquine (positive control), group 3, not infected, but administered with 0.2 ml of normal saline (normal control), while the remaining three (3) groups were infected and treated with 200, 400 and 800 mg/kg body weight of the extract respectfully. The pack cell volume (PCV) was assessed before and after infection and treatment using standard procedure. The mice were sacrificed on the sixth day and blood samples were collected for biochemical analysis using standard methods. The PCV in mice of all groups decrease significantly (p<0.05), except group 3 (normal control) that increased. The alanine transaminase (ALT), aspartate transaminase (AST), total bilirubin level was higher in negative control (group 1) than in all other groups studied, but it was higher in the group treated with 200 mg/kg bd wt of the extract than in the positive control and the groups treated with 400 and 800 mg/kg body weight of the extract. A similar trend was observed in the levels of cholesterol, triglycerides, high density lipolipid (HDL) and low density lipolipid (LDL). The level of creatinine, blood urea and nitrogen were observed to be low in groups 1 and 2, compared to other groups. This study revealed that E. citriodora ethanolic leaf extract does not exact toxic effect on the internal organs like liver, kidney and heart.

The blood glucose- lowering potentials of ethanol leaf extract of Annona muricata were studied. Thirty wistar albino rats were divided into six groups of five rats per group. Group 1 served as “Normal control” animals and received normal rat pellets and water. Diabetes mellitus was induced in Groups 2, 3, 4, and 5 by intraperitoneal injection of alloxan (130 mg/kg). Group 6 rats were administered with 400 mg/kg daily of the extract without induction; group 3 rats were treated with glibenclamide (5 mg/kg body weight), groups 4 and 5 received 200 mg/kg and 400 mg/kg body weight of A. muricata leaf extract daily respectively throughout the duration of the experiment of 14 days. Group 2 rats were induced but not treated with any drug, thus it served as the “Negative control” group. Quantitative phytochemical analysis of the leaf extract was carried out using the Association of Official Analytical Chemists (AOAC) methods. Acute toxicity test of the leaf extract of A. muricata was determined using 12 rats by Lorke’s toxicity testing method. The blood glucose levels of the animals in each group were determined using Accu-chek test strip method. The weights of the animals were determined using a standard electronic weighing balance. The result of the quantitative phytochemical analysis of the leaf showed that the ethanol leaf extract contains the following: phenols (74 mg/100 g), flavonoids (3.70 mg/100 g), tannins (2.95 mg/100 g), oxalate (6.48 mg/100 g), terpenoid (13.88 mg/100 g), phytates (130 mg/100 g), saponins (6800 mg/100 g), alkaloids (570 mg/100 g), cardiac glycoside (1690 mg/100g). Acute toxicity studies showed that LD50 was 3807.89 mg/kg body weight. The results of the average blood glucose levels (mg/dl) of the rats in each group were group 1, 82.6071±7.7524, group 2, 309.3571±163.6923, group 3, 226.7143±132.8182, group 4, 146.5000±140.1465, group 5, 150.4783±81.8340, and group 6, 83.4643±12.5329 for each group respectively. The average body weights of the rats in each group were group 1, 192.8571±22.5844, group 2, 185.7143±33.6759, group 3, 177.1429±36.67500, group 4, 219.2857±21.2908, group 5, 119.5455±23.5993, and group 6, 191.7857±25.2475. The findings from this study suggest that ethanolic leaf extract of A. muricata has notable effect in lowering blood glucose levels in diabetic rats and is a more potent drug in the treatment and management of diabetes mellitus and oxidative stress- related diseases.

Background: Anemia is regarded as public health challenge and is predominant in developing countries due to nutritional deficiencies. Aim/Objectives: The study was carried out to evaluate the biological properties of Ficus capensis fruits and vegetables on some haematological parameters in 2, 4 (dinitrophenyl hydrazine) induced anemic rat. Materials and Methods: Ficus capensis leaves and fruits were separately plucked, sorted cleaned. Twenty male adult rats were purchased from the Department of Veterinary Pathology, University of Nigeria, Nsukka. The animals were divided into 4 groups of 5 rats each on the basis of body weight. The rats in all the groups received 2, 4-DNPH (20 mg/kg body weight) once daily for 7 days to induce anaemia. Group I were fed rat chow alone, group 2 were fed rat chow with ferrous sulphate, group 3 were fed rat chow with Ficus capensis leaves extract and group 4 were fed rat chow with Ficus capensis seed extract. The aqueous extracts of the leaves and fruits were tested for haematinic effects in albino rats. Blood parameters such as Packed Cell Volume (PCV), Red Blood Cell (RBC) count, White Blood Cell (WBC) count and Haemoglobin concentration (Hb) were measured. Results: The result showed that the mean PCV baseline of the rats were (38.72-39.24%), mean PCV of anemic rats (33.01- 34.60%) and the mean PCV of the rats after test of recovery were group 1 (34.10%), group 2 (51.81%), group 3 (40.20%) and group 4 (38.20%).The result showed that the mean HB baseline of the rats were (9.67-10.47 g/dl), mean HB of anemic rats (6.50- 7.10 g/dl) and the mean HB of the rats after test of recovery were group 1 (6.51 g/dl), group 2 (12.32 g/dl), group 3 (9.73 g/dl) and group 4 (9.69 g/dl). The results of the effect of the extracts on the haematological parameters indicated that oral administration of the aqueous extract of Ficus capensis leaves and fruits after 22 days exhibited a significant (P < 0.05) increase in haematinic activity by increasing the blood parameters Hb, PCV, WBC and RBC.

ABSTRACT Objective: to evaluate the influence of acetylsalicylic acid (ASA) on cell proliferation after partial hepatectomy in rats. Methods: 40 male Wistar rats were separated into four groups of ten rats each. Groups 1 and 2 (controls): undergoing 30% partial hepatectomy and, after one day (group 1) and seven days (group 2), to euthanasia; daily administration of 0.9% saline solution (1mL per 200g of body weight). Groups 3 and 4 (experimental): undergoing 30% partial hepatectomy and, after one day (group 3) and seven days (group 4), to euthanasia; daily administration of ASA (40mg/mL, 1mL per 200g of body weight). The absolute number of cells stained with PCNA was counted in photomicrographs, in five fields, and it was calculated the mean of positive cells per animal and per group. Results: the final mean of PCNA+ cells per group was: in group 1, 17.57 ± 6.77; in group 2, 19.31 ± 5.30; in group 3, 27.46 ± 11.55; and, in group 4, 12.40 ± 5.23. There was no significant difference at the two evaluation times in the control group (p=0.491), but there was in the experimental group (p=0.020), with a lower number of PCNA+ cells on the seventh day. The comparison between the two groups, on the first day, showed more PCNA+ cells in the livers of the animals that received ASA (p=0.047), and on the seventh day the number was lower in the experimental group (p=0.007). Conclusion: ASA induced greater hepatocyte proliferation.

Ethanolic Leaf Extract

The study assessed the antiplasmodial activity of the ethanolic leaf extract of Cymbopogon citratus on chloroquine sensitive Plasmodium berghei in mice. Standard methods were used to determine the bioactive components of the leaf extract, acute toxicity test and antiplasmodial activity.  Mice obtained (of body weight 20-25 g) were housed and acclimatized for seven days at room temperature before the commencement of the experiment. A total of 16 albino mice were randomized into four groups of four mice each for acute toxicity while 35 were grouped into five groups of seven mice each for antiplasmodial activity. All the groups 1-5 were infected with P. berghei and were treated for six consecutive days with leaf extract dosage of 200, 400 and        800 mg/kg, standard antimalarial drug (chloroquine) as positive control and normal saline as negative control respectively. Phytochemical screening/ bioactive compounds of the leaf extract reveals the presence of saponins (10.3 mg/g), tannins (2.38 mg/g), flavonoids (1.87 mg/g), terpenoids (19.12 mg/g), steroids (6.21 mg/g) and glycosides (19.9 mg/g) as secondary metabolites. The leaf extract revealed decrease in body weight of the infected mice and did not show any toxicity at all dosage levels used. The antiplasmodial investigation revealed a decrease in percentage parasitaemia level in mice of extract treated groups compared with mice infected and not treated. The parasitaemia reduction was higher in 800 mg/kg than 200 mg/kg and 400 mg/kg. This significant decrease (P<0.05) in percentage parasitaemia level in the study was dose and time-dependent. The extract showed significant (p<0.05) antiplasmodial activity and could serve as possible candidates for the development of new effective drugs for the treatment of malaria.

Background: Alloxan is widely used to induce experimental diabetes mellitus (DM) in animals with different grades of disease severity by varying the dose of Alloxan used. This method has however be questioned by recent research work as an appropriate technique for the induction of diabetes. Objective: To provide a simple, yet concise and reproducible experimental procedure and model for Alloxan-induced DM in rats. Methods: The study was divided into 2 separate experiments. Experiment 1: Alloxan was administered, into four subgroups each (group 1- 100 mg of Alloxan /kg of rat body weight, group 2- 120 mg/kg, group 3- 150 mg/kg, and group 4- 170 mg/kg); in each subgroup, the dose of Alloxan was administered at different concentrations (20 mg/ml, 10 mg/ml, 5 mg/ml and 4 mg/ml) in groups of 10 rats each. The pre-induction fasting period was also varied between groups. Experiment 2:Following a pre-induction fasting period of 36 hours, animals received 150 mg Alloxan /kg body weight and at a concentration of 20 mg Alloxan/ ml. Result:Alloxan administered intraperitoneally at 150 mg/kg of rat body weight, at 20 mg/ml and following a pre-induction fast period of 36 hours yielded the most favorably conditions with the least recorded mortality. Conclusion: From the results of this study, it can be concluded that alloxan is a diabetogenic drug with a strict protocol of use in inducing a predictable DM in rats and as such, this model is a standard and reproducible technique for the induction of DM in experimental rats.

Diabetes mellitus (DM) is a metabolic disease in which there are high blood sugar levels. Type 2 is due to the cells of the body not responding properly to the insulin produced. The aim of this study was to evaluate the enzyme activity in glutathione peroxidase in type 2 diabetic rats induced streptozotocin Wister rats. Enzyme linked immunosorbent assay (ELISA) methods was used. Thirty-two (32) adult rats of Wister strain weighing between 120 g – 200 g of both sexes equally were used. Streptozotocin was used to induce diabetes after high fat diet. The rats were randomly grouped into 4 groups of 8 rats; group 1 are rats fed with only feed and water, group 2 were given 37 mg/kg of streptozotocin with feed and water, group 3 had 37 mg/kg of streptozotocin, feed, water and treated with 2ml of freshly prepared bitter leaf extract daily, group 4 had feed, water, 37mg/kg of streptozotocin and treated with 5 mg/kg of glibenclamide (anti diabetic drug). Severity of the induced diabetic state was assessed by daily and weekly monitoring of body weights and blood glucose levels. The result of fasting blood sugar shows a significant difference (P<0.05) at group 3(7.72±0.99) compared to group 4(9.93±1.22) in week 2.There is also a significant decrease (p<0.05) at group 3(7.72±0.99) compared to group 4(9.90±1.24) in week 3.There is also a significant decrease (p<0.05) at group 3(6.22±1.20) compared to group 46.50±0.70) in week 5. There is a significant increase (p<0.05) at group 1(7.63±0.71) compared to group 4(5.78±1.40), group 2(7.45±0.87) compared to group 4(5.78±1.40)in week 4.There is also a significant decrease in GPX activity in group at group 1(424.59±102.65) compared to group 2(307.34±75.66). There is no significant difference (p>0.05) at group 2(307.34±75.66) compared to group 3(204.31±46.51). There is also no significant difference (p>0.05) at group 2(307.34±75.66) compared to group 4(206.12±55.37). No significant difference (p>0.05) at group 3(204.31±46.51) compared to group 4(206.12±55.37). In conclusion, the result of this study suggest that bitter leaf extract reduced glucose level and has no  damage effect on the liver.

Monosodium glutamate (MSG) is a flavor enhancer. Its toxicity in a malnourished state appears not to have been fully investigated. This study was carried out to determine the effects of MSG on malnourished rats. Rats were randomly assigned into four groups of five rats/group. Group 1 rats were fed with malnourished feed; Group 2 rats received malnourished feed with dosed 1.6 mg/g MSG per body weight; Group 3 rats were fed with normal feed and dosed 1.6 mg/g MSG per body weight and Group 4 rats served as the control group (normal healthy rats) and were fed with normal feed for 28 days. After 28 days, the rats were sacrificed with the liver harvested and blood samples collected. Results from the study showed that malnourished rats had significantly lower levels of oxidative stress biomarkers including, anti-oxidants compared with the control. The levels of malondialldehyde concentration and xanthine oxidase activity were high in malnourished fed rats. Aspartate aminotransferase and alanine transaminase levels of malnourished and normal rats administered MSG were significantly low compared to the normal healthy suggesting that labialization occurs in liver leading to leakage of these enzymes from the liver to the serum. Malnourished rats showed significant decrease in body weight losing 48 grams after 28 days compared to malnourished and normal rats fed with MSG which recorded significant increase in body weight after 28 days adding 26 g and 42 g respectively.
