Aim: The current study determined phytochemical constituents evaluated the acute and sub-chronic toxic profiles of Lannea acida methanol leaves extract (LAMLE) in Wistar albino rats Methodology: The phytochemical screening of LAMLE was conducted using standard methods. A total of 31 male albino rats were used for the antioxidant studies. A total of 31 male albino rats were used for the toxicological study. The LD50 was determined using six (6) rats according to OECD, 2001 using fixed limit dose. For the sub-chronic study, the rats were divided into five (5) groups of five (5) rats. Control group (group 1) received distilled water orally 2ml/kg. Groups (2-5) received doses of 250, 500, 1000, 2000 mg/kg of the extracts. The experiment lasted for 28 days. Results: The phytochemical screening revealed the presence of Flavonoids, Phenols, Tannins, Saponins, Alkaloids and Steroids. The LD50 of the extract was found to be greater than 5000mg/kg. There were significant reduction in the concentration of ALT, ALP and ALB (P<.05) in the group that received the highest dose of the extract when compared to the normal control while other liver biomarkers were not significantly different (P>0.05) from the control. The sub-chronic dose of 2000mg/kg of the extracts shows significant (P<.05) decrease in all kidney function biomarkers except chloride when compared to the control. The haematological parameters (WBC, RBC, HGB, Neutruphils) showed a significant decrease in Group 5 when compared to the normal control group while MCV and lymphocytes showed significant decrease (P<.05) when compared to the control.   Conclusion: The result suggests that the methanol leaves extracts of Lannea acida is relatively safe and can be used in medicinal formulations.

Aim: The present study was designed to investigate the invivo antioxidant effects of coconut (Cocos nucifera) water extract in wistar albino rats. Methodology: Thirty (30) male wistar albino rats of mean weight 128 g were used for the study. The animals for the study were grouped into five (5) of six (6) rats each. Group 1 served as the normal control group that received feed and water only while groups 2, 3, 4, and 5 served as the test groups that were orally given 10 ml, 20 ml, 30 ml, and 40 ml of the coconut water extract for 28 days. The rats were sacrificed after 28 days and the blood samples were collected for biochemical analysis.  Results: From the result obtained there is a significant increase (p< 0.05) between the normal control group (group 1) and the test group (group 2) that received 20 ml of the coconut water extract for MDA. There is a significant increase (p< 0.05) between the normal control group (group 1) and the test groups (groups 2 and 5) that received 10 ml and 50 ml of the coconut water extract for SOD. Also, there is a significant increase (p< 0.05) between the normal control group (group 1) and the test groups (groups 2, 3 and 4) that received 20 ml, 30 ml and 40 ml of the coconut water extract for Catalase. For GSH and Vitamin C, there is a significant increase (p< 0.05) between the normal control group (group 1) and the test groups (groups 2, 3, 4 and 5) that were orally given 10 ml, 20 ml, 30 ml and 40 ml of the coconut water extract. Conclusion: The present investigation showed that the coconut water extract increased antioxidant properties in wistar albino rats and may also be used pharmacologically in the treatment of diseases implicated by free radicals.

Zidovudine administration either in single or fixed-dose combination usually results in a decrease in body weight and in some cases thrombocytopenia. The present study investigated the body weight and platelet count changes observed in zidovudine pre-administered Wistar albino rats on treatment with ethanolic extracts of the leaves Annona muricata (AM) and roots of Fagara zanthoxyloide (FZ). Plants samples were collected from Alakahia community, Rivers state and Opoo community, Ogun state; while Wistar albino rats were grouped into normal control, negative control (receiving zidovudine at 100 g/ml/Kg bw), AM and FZ extract treatment (at 4.5 and 3.8 g/ml/Kg B.W respectively) groups with analysis performed bi-weekly. All tests were performed using standard procedures with all reagents of analytic grade. Phytochemical screening of the extracts showed significantly high amounts of alkaloids (10.47- 21.15 mg / 100 g), phenols (10.60-15.22 mg / 100 g) and tannins (14.23 - 50.19 mg / 100 g). The investigation into their proximate compositions also showed high fat (5.78 ± 0.02) in FZ, moisture (10.47 ± 0.05) in AM and fibre (7.37 ± 0.03) in FZ. The amino acid phenylalanine (5.10-6.01 g / 100 g), isoleucine (4.44-5.20 g / 100 g), lysine (4.03 -5.31 g / 100 g) was observed to be available in the extracts. In the normal control group body weight increased by 20.75 g at week 6 while administration of Zidovudine, resulted in a decreased in bodyweight by 1.14 g in week 2 and 3.32 g in week 6. Extract treatment caused a significant increase (p≤0.05) in body weight by 17.95g (AM) and 18.23g (FZ) at week 6. Platelet count was also observed to significantly decrease (p≤0.05) by 33.42% in the negative control group when compared to the normal control. This was observed to significant increases in extract treatment by 49.56% (AM) and 51.32% (FZ). The results thus suggest a possible beneficial effect of the extracts of AM and FZ in checkmating the weight and platelet loss observed as a side effect of zidovudine therapy as well as the possible use in haemorrhagic conditions to reduce bleeding without thromboembolism.

The high costs and extensive time needed for the treatment of critical-sized bone defects are still major clinical concerns in orthopedic surgery; therefore, researchers continue to look for more cost and time-effective methods. This study aims to investigate the effects of a decellularized omentum scaffold with a combination of platelet-rich plasma (PRP) and mesenchymal stem cells on the healing of critical-sized bone defects. Wistar albino rats (n = 30) were investigated in five groups. Critical-sized bone defects were formed on bilateral radius shafts. No scaffold, decellularized omentum, omentum with PRP and omentum + mesenchymal stem cells was used in group 1 (control group), 2, 3 and 4, respectively. In addition, omentum with a combination of mesenchymal stem cells +PRP was used in group 5. After 6 weeks, both radiological and histological healing were evaluated comparatively among the groups. After the use of a decellularized omentum scaffold, vitality of new cells was maintained, and new bone formation occurred. When compared to the control group, radiological healing was significantly better (p = 0.047) in the omentum and omentum + PRP-treated groups. Furthermore, histological healing was better in the omentum and omentum + PRP-treated groups than the control group (p = 0.001). The use of a decellularized omentum scaffold is suitable in the healing of critical bone defects.

This study aimed to investigate whether berberine nanoparticles (BBR-NPs) and/or cisplatin supplementation could prevent hepatocarcinogenesis-induced by N-nitroso-diethylamine (DENA) in male rats. Male Wistar albino rats were divided into five groups; Group 1: Control; Group 2: DENA-CCl4; Group 3: DENA-CCl4+Cisplatin; Group 4: DENA-CCl4+BBR-NPs; Group 5: DENA-CCl4+Cisplatin+BBR-NPs. DENA-CCl4 significantly increase AST, ALT, ALP, LDH, GGT, AFP activities and total bilirubin, while, 5, NT,  total protein and albumin decreased. DENA-CCl4 treatment caused increment in MDA levels and reduction in SOD, CAT, GPx and GSH in liver tissues. Moreover, DENA-CCl4 increase the gene expression of ADAM17 and TNF-α however,  P53 was declined. In addition, DENA-CCl4 caused severe histopathological lesions in the liver tissue. Interestingly, administration of berberine nanoparticles alone or in combination with cisplatin improves the hepatocarcinogenesis induced by DENA-CCl4 on the physiological, biochemical, molecular and histological levels by decreasing oxidative stress and preserving gene expression of ADAM17, TNF-α and P53. The present findings suggest that BBR-NPs with cisplatin might offer a promising strategy for the prevention of liver cancer.

The present investigation was carried out to assess the antioxidative potential of Broccoli sprouts aqueous extract (BE) against triazophos (TZ) induced oxidative stress (OS) in brain and spleen. In the experimental setup, six groups of rats were formed; Control (group 1), BE (group 2), TZ (group 3), and also BE+TZ groups such as BE1 (group 4), BE2 (group 5) and BE3 (group 6) groups. Rats were orally intubated for 30 days as per experimental design. After sacrifice, OS biomarkers viz; catalase (CAT), superoxide dismutase (SOD), glutathione reductase (GR), glutathione peroxidase (GPx), glutathione-S-transferase (GST), and lipid peroxidation (LPO) levels were determined in brain and spleen. Acetylcholinesterase (AChE) activity was observed in plasma and brain samples. Histological study of the spleen in TZ rats showed increased thickness of capsule, congestion and hypocellularity in follicles of spleen’s white pulp and the histoarchitecture was restored in TZ+BE group rats. TZ caused degenerative changes in brain histology and rats showed mild congestion along with haemorrhage in the cerebral cortex. Results suggest that TZ exposure is associated with neural toxicity along with altered spleen stress biomarkers, which further corroborates with histopathological findings. It is inferred that BE exerts multi-mechanistic protective effects against TZ induced neuro-splenic toxicity which is attributable to its protective antioxidant actions.

Effects of n-butanol fraction of Gongronema latifolium leave extract on some kidney function and histological parameters in (CCl4) carbon tetrachloride-induced oxidative damage in Wistar albino rats were assessed. Fifty-four (54) Wistar albino rats were divided into treatment and LD50 groups. The treatment group was further divided into seven groups of 6 animals each by the randomized random design method, each were allowed food and water ad libidium. Group A (normal control) was given feed and water, Group B (vehicle control) was injected with olive oil intraperitoneally, while the rest groups (C, D, E, F and G) were injected intraperitoneally with a single dose of CCl4 (148 mg/kg) at 1:1 (v/v) solution in olive oil and all the animals were fasted for 36 hours. This was repeated once every week for a period of four (4) weeks. At the end of 28 days of treatment, there was significant (p<0.05) reduction in weight change of CCl4-induced control rats when compared with the normal control and induced treated groups. Kidney function studies showed that there was significant (p<0.05) increase in creatinine and urea levels of CCl4-induced control group when compared with the normal control and induced treated groups but there was no significant (p>0.05) difference between the normal control and induced treated groups. Also, the kidney homogenate revealed significant (p<0.05) decrease in superoxide dismutase, catalase and glutathione peroxidase activities in CCl4-induced control rats when compared with the normal control rats but there was no significant (p>0.05) difference between the normal control and induced treated groups. However, malondialdehyde concentration was significantly (p<0.05) higher in CCl4-induced control rats when compared with the normal control and induced treated rats. These findings suggested that n-butanol fraction of methanolic leave extract of G. latifolium may have anti-nephrotoxic and antioxidative effects against CCl4-induced kidney damage in rats.

Adipose tissue is an endocrine organ and has central role in interaction with other organs or tissues while propolis can induce lipolysis. Therefore, the aim of this study is to provide detailed information about adipose tissue homeostasis modifications and body composition during propolis supplement consumption. Twenty male Wistar albino rats (8 weeks) were divided into two groups of 10 animals each and fed for 90 days with two different types of diets: standard for the control group (diet C) and standard diet + 2% propolis (diet P). Thyroid hormones did not show differences, while ghrelin and adiponectin decreased in the group that was fed propolis. Insulin, leptin, and non-esterified fatty acids also increased along with reduced body weight and fat, in addition to increased lean mass when propolis was in the diet. We conclude that propolis could decrease ghrelin and adiponectin but increase non-esterified fatty acids and insulin secretion, which improves body composition.

Lipid lowering effect of polyherbal formulations using eight different plants was evaluated in triton and diet induced hyperlipidemic models of wistar albino rats. Formulations such as Tablet, Syrup and Suspension inhibited the elevation in serum cholesterol and triglyceride levels on Triton WR 1339 administration rats. The formulations at the same dose level significantly attenuated the elevated serum total cholesterol and triglycerides with an increase in high-density lipoprotein cholesterol in high-fat diet-induced hyperlipidemic rats. The standard drug Niacin showed slightly better effects. The treatment with herbal formulations produced 30-35 percentage improvement in oral glucose tolerance. Similarly all the formulations also reduced the elevated C-reactive protein which is a marker of Hyperlipidemia. In histopathological study it was found that treatment of polyherbal formulation significantly reduced the plaque size in aorta compared with HFD treated control group. The outcome of the study reveals the lipid lowering activity of polyherbal formulations in dyslipidaemic conditions by interfering with the biosynthesis of cholesterol and utilization of lipids.

Abstract Ethnopharmacological relevanceAnemia is a very serious condition in Zambia. One of the plants that has been used traditionally is Phyllanthus muellerianus where different parts of shrub are used to treat a number of diseases in Zambian folklore medicine. Earlier studies have investigated medicinal properties of its aqueous root extracts. This study evaluated the effect of P. muellerianus roots on the hematological indices of albino rats and determined its phytochemical profile. Aim of the studyTo carry out phytochemical screening of the root extract and assess the ant-anemic effect of the aqueous extract on laboratory rats with tail-bled induced anemia Materials and MethodsThirty-six male albino rats placed in six groups were used for the study. The groups comprised the 100, 200, and 400 mg/kg plant extract, Ranferon (200 mg/kg) positive control, anemic non treated control and a normal (non-anemic) control. Anemia, induced through bleeding of the rats, was defined as hemoglobin (Hb) levels less than 12 g/dL. The anti-anemic potential of the plant was determined by comparing its effect on the hematological parameters of rats on treatment to that of the control group.ResultsAfter treatment, rats on the 400 mg/kg plant extract dose showed the greatest increase in the mean values for Hb, Packed cell volume (PCV) and RBC count were 43.3±1.2%, 15.4±0.3 g/dL and 6.3±0.3 x106 /mL respectively, when compared to the negative control group (P < 0.05). Phytochemical screening revealed positive results for alkaloids, flavonoids, saponins, glycosides, steroids, triterpenoids and tannins with varying amounts.Conclusions. The aqueous root extract of P. muellerianus was efficacious against anemia in a dose-dependent manner. The phytochemical compositions seem to be responsible for its hematopoietic properties. Thus, the root decoction of P. muellerianus is useful in alleviating anemia and the results lend credence to its use in traditional medicine in the management of anemia.
