Aim: To evaluate the nephroprotective property of Cnidoscolus chayamansa aqueous leaf extract in diabetic rats. Study Design: Rats were randomly divided into five groups with group 1 as the normal control. Diabetic was induced in groups 2-4. Group 2 was used as the test control while groups 3 and 4 were treated with different concentrations of the leaf extract; group 5 was treated with the standard drug, glipizide. Place and Duration of Study: Departments of Biochemistry and Anatomy, University of Jos, Nigeria, between August to November, 2019. Methodology: Fourty (40) male albino Wistar rats were grouped into five groups. The rats were treated for fourteen days and then sacrificed by decapitation after anaesthesia. Blood was collected for biochemical parameters; kidney was excised and stored in formaldehyde until required for histopathological study. Serum urea, creatinine, uric acid, sodium, potassium, chloride and bicarbonate were determined using appropriate methods. Results: The test control had a significant (P < .05) decrease in the concentrations of Na+, Cl- and HCO3- ions; significant (P < .05) increases in serum K+ ion, urea, uric acid and creatinine. Treatments of the test groups with the different doses of the leaf extract and the standard drug increased the concentration of Na+ ion which was not significantly (P < .05) different from the test control. On the other hand, the concentration of Cl- and HCO- ions  were significantly (P < .05) increased; the concentrations of K+, urea, uric acid and creatinine were significantly (P < .05) decreased. The histochemistry of the kidneys revealed that the injury brought about under diabetic condition was ameliorated with the treatments with the low and high doses of the leaf extract, and the standard drug. Conclusion: The results show that the aqueous leaf extract has nephroprotective property.

Aqueous extract of Duranta repens leaves was investigated for its allelopathic effect on Solanum lycopersicum seedlings germinated and grown under salinity condition. The study was carried out using both laboratory petridish and pot assays to simulate the plant’s immediate environmental conditions. The experiment consisted of 5 groups (1-5) each containing 4 replicates (of 10 seeds). Group 1 was treated with distilled water; Group 2 was treated with 5 mM NaCl; Group 3 was treated with Duranta repens aqueous leaf extract, Group 4 was treated with a mixture of 5 mM NaCl and the extract (2:1 v/v) and Group 5 was treated with a mixture of 5 mM NaCl and the extract (1:2 v/v). Results from the studies revealed that treatment with NaCl caused significant (p < 0.05) reduction in percentage germination and growth parameters (plumule and radicle lengths) of S. lycopersicum seedlings, when compared to those treated with distilled water and D. rupens aqueous leaf extract. NaCl treatment (Group 2) also caused an increase in malondialdehyde (MDA) and also increased the activities of superoxide dismutase (SOD) and catalase (CAT) while reducing chlorophyll concentration of the plants. However, in the presence of the extract, the adverse effects of the NaCl were attenuated, implying that the extract improved tolerance of S. lycopersicum seedlings. In conclusion, the findings of this study indicate that the constituents of the extract may play a positive role in plant survival under saline conditions and could be employed in the management of soil salinity problem in agriculture.

The Impact

The blood glucose, total serum cholesterol, High Density Lipoprotein (HDL) and Triglyceride (TRIG) levels of all rats in each group were determined before induction, post-induction with alloxan and post treatment with various concentrations of extract and standard drug. The alloxan diabetic rats treated with gliberclamide and aqueous leaf extract of Annona muricata showed average means of body weights as; (235.73±3.14a, 263.94±2.25a and 236.5±1.74a) respectively after 4 weeks of treatment. The Glucose level revealed; 168.43±5.06e, 65.29±4.57f and 57.86±3.93e respectively. Lipid profile raised significantly post exposure of diabetic rats to both standard drug and extract after 4 weeks of treatment. Therefore, A. muricata compared favorably with the standard drug in the context of diabetes management.

Background: The extract of Hibiscus sabdariffa commonly known as Sobo is widely consumed for its nutritional and health benefits. This study investigated the effect of aqueous leaf extract of  H. sabdariffa on anemic condition caused by phenylhydrazine in rats. Materials and Methods: Thirty (30) rats used for this study were divided into three groups of 10 rats each. Group 1 received distilled water and served as control. Group 2 received phenylhydrazine (40 mg/kg, i.p.). Group 3 was treated with phenylhydrazine (40 mg/kg, i.p.) 30 minutes prior to administration of (200 mg/kg, p.o.) aqueous extract of H. sabdariffa (Sobo) once daily for 14 days. At the end, 2 ml blood samples were collected through cardiac puncture into clean sample bottles containing ethylenediamine tetra acetic acid (EDTA) for hematological analyses. Results: Sobo significantly increased (P<0.05) hemoglobin (Hb) concentration and packed cell volume (PCV) in the phenylhdrazine-treated rats. Also, Sobo significantly (P<0.05) increased total white blood cell (TWBC) in phenylhydrazine administered rats. However, the extract did not produce any significant effect on mean corpuscular hemoglobin concentration (MCHC) relative to control and anemic groups. Conclusion: The findings from this study revealed that the aqueous extract of H. sabdariffa demonstrates anti-anemic effect in rats treated with phenylhydrazine, suggesting its ethno-pharmacological beneficial effect in anemic conditions.

This study was performed to investigate the effects of aqueous Imperata cylindrica root extract on hepatic enzyme levels of alloxan-induced diabetic male Wistar rats. Forty (48) male wistar rats were divided into six groups consisting of eight animals each. Diabetes mellitus was induced using intraperitoneal administration 150 mg/kg body weight of alloxan and treatment was carried out for a period of 28 days. The first group served as the normal control and received only feed and water ad libitum. In Group 2 were diabetic rats without treatment with extracts. Group 3: diabetic rats treated with 200 mg/kg aqueous Imperata cylindrica root extract. Group 4: diabetic rats treated with 400mg/kg aqueous Imperata cylindrica root extract. Group 5: diabetic rats treated with 600mg/kg ethanol extract of aqueous Imperata cylindrica root extract. While Group 6 was diabetic rats treated with 0.5mg/kg Glibenclamide. The liver enzymes alanine aminotransferase, aspartate aminotransferase and alkaline phosphatase levels were significantly (p < 0.05) changed in rats treated with Alloxan (150mg/kg b.w.) while treatment with the respective dosages of extracts significantly changed the levels of these parameters to normal. The results obtained indicate that the different doses of aqueous Imperata cylindrica root extracts were beneficial in mending damages to the liver caused by Alloxan monohydrate in the male wistar rats.

Background: The association between diabetes mellitus and inflammation is established but the use of non-steroidal anti-inflammatory drugs is not without some health risk. Aim: The study was aimed at comparing the levels of some inflammatory biomarkers in diabetic rats treated with aqueous leaf extract of Terminalia catappa, non steroidal anti-inflammatory drugs (NSAIDs) and exogenous insulin. Materials and Methods: Thirty six (36) Wistar rats were assigned to 6 groups of 6 animals each. Group 1 and 2 served as normal and diabetic controls and received orally 5ml/kg body weight of distilled water. Group 3 was diabetic treated orally with 130mg/kg body weight of aqueous leaf extract of Terminalia catappa.  And groups 4, 5 and 6 were administered orally with aspirin (30mg/kg), meloxicam (2mg/kg) and 0.75U/kg body weight of insulin subcutaneously. Diabetes was induced with intraperitoneal injection of 150mg/kg body weight of alloxan solution and diabetes confirmed after 72 hours with blood glucose levels ≥200mg/dl. The experiment lasted for 14 days and blood was collected by cardiac puncture for serum analysis of C-reactive protein, Interleukin-6 and Fibrinogen by ELISA method. Results: The results showed significant (P<0.05) increase in serum levels of C-reactive protein, Interleukin-6 and blood fibrinogen in diabetic group compared to control. These inflammatory biomarker were significantly (P<0.05) reduced by the extract, aspirin, meloxicam and insulin.  Conclusion: The reduced levels of C-reactive protein, Interleukin-6 and fibrinogen by aqueous leaf extract of Terminalia catappa was significant compared to aspirin and meloxicam. This may present the extract as a potent anti-inflammatory agent and could complement the function of insulin in diabetes treatment.

Background: Ocimum gratissimum is an ethnopharmacological plant with numerous healing potentials. But there is paucity in scientific literature on its impact on the blood cells. Aim and Objective: The present study was intended to evaluate the dose and time-dependent effect of aqueous leaf extract of Ocimum gratissimum on some haematological in albino Wistar rats. Methods: Twenty four rats were randomly assigned to four equal groups. Group 1 was control, groups 2, 3 and 4 were given 450 mg/kg, 800 mg/kg and 1800 mg/kg respectively of the extract daily for 30 days. All rats had free access to water and rat chow. Results: The result showed a significantly lower RBC count in groups 3 and 4 when compared with control (p<0.05 and p<0.01 respectively). PCV was significantly lower in group 4 than control (p<0.05). Platelet count was significantly lower in group 4 than control (p<0.05) and group 2 (p<0.05). A significant increase in WBC count was observed in groups 2 and 3 when compared with control (p<0.05 and p<0.01 respectively). A significant reduction in neutrophil count was observed in groups 2, 3 and 4 compared with control (p<0.05; p< 0.05 and p<0.01 respectively). There were significant increases in lymphocyte counts in groups 2, 3 and 4 when compared with control (p<0.05, p<0.01 and p<0.01 respectively). There were no significant changes in MCV, MCH and MCHC in the groups. Conclusion: In conclusion, aqueous leaf extract of Ocimum gratissimum causes reduction in RBC count, PCV, platelet count and neutrophil count but causes increases in total WBC count and lymphocyte count.
