Aqueous Leaf Extract

Background: Plants are important source of chemical substances with therapeutic effects. Although, the promising potentials for good number of medicinal plants are being established, there exists in developing countries where people resort to herbal plants without proper awareness of the associated risks particularly in event of excessive or chronic use. Hence, the need to evaluate the histological and biochemical effects of aqueous leaf extract of Cadaba farinosa used traditionally for treatments of gastrointestinal parasites, cancer and diabetes in North-Eastern Nigeria. To evaluate the histological and biochemical effects of aqueous leaf extract of Cadaba farinosa on liver of adult Wistar rats.Methods: Twelve adult Wistar rats of both sexes were used and divided into four groups of three rats each. Group 1 served as control. Aqueous leaf extract were orally administered for 28 days at doses of 100, 200 and 300mg/kg respectively. Biochemical and histological analysis were performed.Results: This study showed significantly elevated levels of aspartate transaminase, alkaline phosphatase and alanine transaminase in animals treated with Cadaba farinosa (especially the highest dose 300mg/kg) compared to negative control. Elevated liver enzymes were corroborated by histopathological changes of liver exhibiting ballooning degenerations and steatohepatitis.Conclusions: Cadaba farinosa causes hepatic injury. Hence, further work needs to be done to ascertain whether reducing the dose of Cadaba farinosa would ameliorate this effect. Authors speculate that injury to multiple organelles including fat droplets and endoplasmic reticulum contribute to this characteristic finding.

Background: The process of wound healing is influenced by various factors such as age, hormones, and wound care. Wound care is done to accelerate wound healing which can be done by various methods, one of them is traditional care. Traditional wound care can use medicinal plants. Rhodomyrtus tomentosa is a medicinal plant that has an antioxidant, anti-inflammatory, antitumor and antibacterial content. Thus this study aims to evaluate the effectiveness of the antiseptic solution of the Rodhomyrtus tomentosa leaf extract on wound healing in male Wistar rats. Method: this research is pure experimental research with post test only control group design. Thirty male white rats were divided into five groups, namely negative control, positive control, Rhodomyrtus tomentosa leaf extract 15%, 30%, and 60%. Rhodomyrtus tomentosa leaf extraction was carried out by maceration method with 70% ethano solvent. The extraction results are divided into 3 concentrations (15%, 30% and 60%). The wound healing process was evaluated by measuring the length of the wound manually from 0 to 10 days in each group. Meanwhile, the number of fibroblast cells was calculated through hematoxylin eosin (HE) staining and observed using an Olympus CX41 microscope with a 10x magnification and objective lens magnification in 3 fields. Result: There was a significant difference in the reduction in wound length (p =< 0,000) between the five experimental groups (Rhodomyrtus tomentosa leaf extract solution 15%, 30% and 60%, negative control and positive control. Solution of rhodomyrtus tomentosa leaf extract accelerated the increase in the number of fibroblasts compared to the negative control group (p = 0.003), but did not make a difference (p = 0.403) with the positive control group. Rhodomyrtus tomentosa leaf extraction solution had the same microscopic effect on the number of fibroblasts with a positive control group given 0.9% NaCl solution. Conclusion: There was a significant difference in the number of fibroblasts between all groups, but no difference in wound healing length.

Diabetes mellitus is a metabolic disease that always increasing in prevalence. Excessive glucose intake and oxidative stress that can lead to damage to the pancreatic cell or insulin resistance, are such factors that influence the occurrence of diabetes mellitus. Graptophyllum pictum (L.) Griff leaf contains active metabolites such as flavonoid which able to decrease free radical levels. This study aimed to prove the effectiveness of Graptophyllum pictum (L.) Griff leaves extract on blood glucose levels in alloxan-induced Wistar rats. In this study, twenty-five male Wistar rats were divided into five groups. On day 0, the negative control and each treatment group injected with 125 mg/kg dose of alloxan and would be checked on 4th day. On the 4th day after the rats had diabetes, normal group (K-1) was given only standard feed, Negative control (K-2) was given only alloxan intraperitoneally on day 0, first treatment group (K-3) was given 50 mg/kg dose of Graptophyllum pictum (L.) Griff, second treatment group (K-4) was given 100 mg/kg dose of the leaf extract, and the third treatment group (K-5) was given the leaf 200 mg/kg dose of the leaf extract. On the 10th day, fasting blood glucose was taken from the rats. Post-test only group design was used to be the experimental design. There were significant differences in the treatment groups (K-3, K-4, and K-5) compared to the negative control group (K-2) after treatment. The mean of blood glucose levels decreased with the increased doses of Graptophyllum pictum (L.) Griff leaf extract treatment. The treatment groups (K-3, K-4, and K-5) were not significant compared to the normal group (K-1).

AbstractThe current study provides novel results on the synthesis of bimetallic nanoparticles (BNPs) of gold and palladium (Au–Pd) with an eco-friendly and non-toxic aqueous leaf extract of plant Citrus limon. The BNPs were characterized and toxicity bioassay was examined on the larvae of the pathogen vectors such as Anopheles stephensi and Aedes aegypti mosquitoes. The predation efficiency test was evaluated on the invertebrate non-target organisms such as natural predatory nymphs of dragonfly and damselfly. The results of material characterization using UV VIS spectroscopy confirmed the synthesis of Au–Pd BNPs with the appearance of the SPR bands. FT-IR spectroscopy indicates the presence of functional groups containing high amounts of nitro compounds and amines on the surface of BNPs. TEM result shows the presence of spherical polydisperse Au–Pd BNPs in the sample. The XRD pattern displayed the semi-crystalline nature and the changes in the hydrodynamic size and surface potential was determined for the sample at 0 h, 24 h, 48 h, and 72 h of synthesis through DLS and ZP analysis. Au–Pd BNPs Bioassay provided the effective lethal concentrations (LC50) against the I–IV instar larvae of An. stephensi and Ae. aegypti after 24 h, 48 h, and 72 h of exposure. The LC50 obtained from the larvicidal bioassay was used to test its effect on the predation efficiency of the selected nymphs which showed increased predation from 40 to 48 h of exposure as compared to the negative control. Hereby, we conclude that Au–Pd BNPs bioassay shows toxic mosquito larvicidal activity at the selected concentration with no lethal effect on the predation efficiency of the selected stage of the predatory non-target aquatic invertebrate insects.
