Ethanolic Leaf Extract

Cadmium is a well-known environmental pollutant that has been proven to be nephrotoxic and hepatotoxic in the body. In this study, the effect of ethanolic leaf extract of Irvingia gabonensis (O’Rorke) Baill (IG) against cadmium-induced nephrotoxicity and hepatotoxicity in Wistar albino rats was investigated. 30 female wistar rats of weights between 98-153g were grouped into 6 groups of 5 animals each. Group 1 served as the control and was placed on rat feed and water. Groups 2, 3, and 4 were administered 10mg/Kg body weight (mg/kgbw) of cadmium chloride (CdCl2) only,10mg/Kgbw CdCl2 and 200mg/kgbw extract, 10mg/Kgbw CdCl2 and 400mg/kgbw extract, respectively. Groups 5 and 6 were given 200mg/kgbw and 400mg/kgbw of IG extract respectively and the treatments lasted for 28 days. Results obtained revealed significant (p<0.05) increases in the serum levels of all renal and liver function biomarkers in group 2 (CdCl2 only) as compared with the control. There were however significant (p<0.05) decreases in the serum levels of the assayed parameters when groups 3 and 4 were respectively compared with group 2. It can therefore be concluded that ethanolic leaf extract of Irvingia gabonensis (O’Rorke) Baill enhances the integrity of the kidneys and liver of cadmium-induced wistar albino rats.

Abstract Pesticides are viewed as a major wellspring of ecological contamination and causing serious risky consequences for people and animals. Imidacloprid (IM) and hexaflumuron (HFM) are extensively utilized insect poisons for crop assurance on the planet. A few investigations examined IM harmfulness in rodents, but its exact mechanism hasn’t been mentioned previously as well as the toxicity of HFM doesn’t elucidate yet. For this reason, the present study was designed to explore the mechanism of each IM and HFM–evoked rat liver and kidney toxicity and to understand its molecular mechanism. 21 male Wistar albino rats were divided into 3 groups, as follows: group (1), normal saline; group (2), IM; and group (3), HFM. Both insecticides were orally administered every day for 28 days at a dose equal to 1/10 LD50 from the active ingredient. After 28 days postdosing, rats were anesthetized to collect blood samples then euthanized to collect liver and kidney tissue specimens. The results showed marked changes in walking, body tension, alertness, and head movement with a significant reduction in rats’ body weight in both IM and HFM receiving groups. Significant increases in MDA levels and decrease of GHS levels were recorded in liver and kidney homogenates of either IM or HFM groups. Liver and kidney tissues obtained from both pesticide receiving groups showed extensive histopathological alterations with a significant increase in the serum levels of ALT, AST, urea, and creatinine and a decrease in total proteins, albumin, and globulin levels. In addition, there was upregulation of the transcript levels of casp-3, JNK, and HO-1 genes with strong immunopositivity of casp-3, TNF-ὰ, and NF-KB protein expressions in the liver and kidneys of rats receiving either IM or HFM compared with the control group. In all studied parameters, HFM caused hepatorenal toxicity more than those induced by IM. We can conclude that each IM and HFM provoked liver and kidneys damage through overproduction of ROS, activation of NF-KB signaling pathways and mitochondrial/JNK-dependent apoptosis pathway.

Ethanolic Leaf Extract

The purpose of the present study was to evaluate the laxative and antimicrobial activities of ethanol extracts of leaf and root of Amaranthus viridis L. The laxative activity of ethanolic leaf extract of A. viridis was studied using six groups of wistar albino rats; Group I which served as the negative control received 0.5ml/kg of normal saline, Group II received 10mg/kg of Dulcolax and the rest of the groups (III-VI) received 400, 200, 100 and 50mg/kg of the extract respectively. The laxative activity of the ethanolic leaf extract was expressed as the mean of total weight of faecal output in each group. A significant (p<0.05) dose dependent increase in the faecal output was observed at the 200mg/kg (3.00 ±1.41gm) and 400mg/kg (3.50 ±2.12gm) doses compared with the negative control. The antimicrobial activity was expressed as the diameter of the zone of inhibition hence the minimum inhibitory concentrations were determined. The antimicrobial activity of the A. viridis leaf and root extracts had dose dependent increases in all the tested organisms from their various minimum inhibitory concentrations (MIC). The result confirmed that the leaves and root of A. viridis possess laxative and antimicrobial activity.

Ethanolic Leaf Extract

Byrsocarpus coccineus is an indigenous herb widely dispersed in tropical Africa and commonly known as Crimson thyme. The leaf and root of the plant is noted to possess medicinal benefits in traditional medicine of the Western part of Nigeria. The plant has been reported to possess analgesic, antiplasmodial, inflammatory, antidiarrhic and antipyretic activities. The present study was therefore aimed at determining the sub-acute toxicity of ethanolic leaf extract of Byrsocarpus coccineus. The ethanolic leaf extract of the plant was administered orally at 250, 500, and 1000 mg/kg to three groups A, B and C of Wistar rats respectively for 14 days while the control group D was administered orally with 3ml/kg of distilled water. Blood samples were then obtained from the anaesthetized rats for haematology and serum biochemistry. The result obtained from serum analyses showed a significant increase (p<0.05) in the levels of blood urea nitrogen and creatinine levels while the increase in alkaline phosphatase is not significant for the treated groups B and C compared with the control. It was therefore concluded that high doses of the extract may have untoward effects on the kidney and therefore, the use of the plant extract in high doses should be discouraged.

The aim of this experimental study was to assess the spine development in growing rats following pinealectomy or partial sensorimotor cortical area damage. A total of 68 Wistar albino rats (Rattus norvegicus v. alba f. domestica) aged 3–4 weeks were divided into four groups. In group 1 (n = 22) pinealectomy was performed, in group 2 (n = 24) the sensorymotor cortical area 2 × 1 × 1 mm below the coronal suture was removed. Sham operation consisted of a craniotomy (n = 11) and a craniotomy with a durotomy (n = 11). All surgeries were performed from the left side. The rats were killed four months after surgery and radiography was then made. Scoliosis, C2-T7 lordosis and T7-S1 kyphosis were measured.The brains of rats after sensorimotor cortical area removal were isolated and investigated including histological examination (light microscope). Scoliosis of 9–14 degrees (mean value 10.8) was developed in five animals after pinealectomy; in rats after removal of the sensorimotor cortical area scoliosis of 10–24 degrees (mean value 15.9) was observed in eight animals. The scoliotic curves were non structural. Our results indicate the importance of cortical area damage, together with craniotomy and durotomy in the development of growing rat spine. These damages could cause a disorder of balance between smaller inhibitory and greater facilitating area of central nervous system, controlling the muscular tone and resulting in the development of increased lordosis and kyphosis and non structural scoliosis due to muscle imbalance. Thus the new hypothesis of scoliosis aetiology was introduced.
