Beninese Plant Extracts with Antiplasmodial Activity Select New Allele Variants Msp1 and Msp2 in Plasmodium falciparum.

Natural medicinal products are commonly used as a remedy against malaria infections in African populations and have become a major source of information for the screening of new and more effective antiplasmodial molecules. Therefore, in vitro studies are needed to validate the efficacy of these medicinal products and to explore the potential effects of such drugs on the genetic diversity of Plasmodium falciparum. The current study has investigated the impact of some Beninese plant extracts with antiplasmodial activity on the genetic diversity of P. falciparum. Five (5) ethanolic plant extracts (Dissotis rotundifolia, Ehretia cymosa Thonn, Hibiscus surattensis L., Cola millenii K. Shum, and Costus afer Ker Gawl) and a compound extracted from Ehretia cymosa Thonn (encoded CpE2) were tested against asexual stage parasites of a culture-adapted strain of P. falciparum. Subsequently, the P. falciparum Msp1 and Msp2 markers were genotyped, and the number of allelic variants and the multiplicity of infection (MOI) were compared between drug-exposed and unexposed parasites. All plant extracts have shown inhibitory activity against asexual P. falciparum and selected new allelic variants of the Msp1 and Msp2 genes compared to unexposed parasites. The newly selected allelic variants were K1_100bp and RO33_300bp of the Msp1 gene and FC27_150bp, FC27_300bp, FC27_400bp, and FC27_600bp of the Msp2 gene. However, there was no significant difference in MOI between drug-exposed and unexposed parasites. Our study highlights a source for the selection of new Msp1 and Msp2 alleles after exposure to antimalarial drugs. These findings pave the way for further studies investigating the true roles of these newly selected alleles in P. falciparum.

Anti-psychotic effects of leaf extracts of <i>Palisota hirsute</i> (Thunb.) K. Schum. (Commelinaceae) and <i>Costus afer</i> Ker-Gawl (Zingiberaceae) on ketamine-induced psychotic mice

This study assessed the anti-psychotic activity of the methanol leaf extracts of Palisota hirsute (Thunb.) K. Schum. (Commelinaceae) and Costus afer Ker-Gawl (Zingiberaceae) in Ketamineinduced psychotic mice. Antipsychotic activity of the two plant extracts (Palisota hirsuta and Costus afer) at different doses were assessed using the Ketamine animal model of psychosis. Locomotor and stereotype behaviours were studied in an open-field and transparent chambers, while the force swim test was investigated in a cylindrical glass containing water. From the locomotion test, both doses of the plant extracts tested for activity showed a significant reduction in hyperactivity. Palisota hirsuta and Costus afer (500 mg/kg) antagonised the stereotypy effect induced by Ketamine in the mice. Furthermore, the two doses of Palisota hirsuta (250 and 500 mg/kg) and Costus afer at 500 mg/kg had high anti-depressant activity in that the immobility time recorded during the force swim test was reduced significantly. Palisota hirsuta extract had a good anti-psychotic effect at both the higher (500 mg/kg) and lower doses (250 mg/kg), whereas Costus afer extract had a greater anti-psychotic effect at a higher dose of 500 mg/kg than at a lower dose and these results are similar to those of the positive control drug (Haloperidol).

Anti-Inflammatory Property of Costus afer Ker Gawl Ethanol Leaf Extract in STZ-Induced Diabetic Rats

Costus afer Ker Gawl is an indigenous plant, commonly called a ginger lily, spiral ginger, or bush cane, it has been reported to possess anti-inflammatory properties. The anti-inflammatory activity of C.afer leaf extract in streptozotocin-induced diabetic rats was investigated. Protein denaturation and erythrocyte stabilization assays were used to evaluate in vitro anti-inflammatory activity, and alpha-amylase and alpha-glucosidase enzyme inhibition was used to evaluate in vitro anti-diabetic activity. 60 male Wistar rats were used for the two inflammatory models: the 30 rats were randomly assigned into six groups (n=5) for carrageenan-induced paw edema and cotton pellet granuloma models respectively: Group I: normal, group II: control(untreated), group III: 10mg/kg b.w diclofenac sodium (standard), group IV, V and VI were given 50, 100, 250 mg/kg b.w Costus afer ethanol leaf extract (CAELE) in each of the two models. The study showed that in protein denaturation assay, CAELE and Diclofenac had 56.69% and 80.82% respectively at the highest concentration, erythrocyte stabilization had 80.40% CAELE and 94.88% Diclofenac sodium at the highest dose in a dose-dependent manner. Alpha amylase and alpha-glucosidase showed an increase in percentage inhibition activity at 65.44% and 43.72% respectively against acarbose (standard) at 56.01%. However, in the cotton pellet-induced granuloma model, the concentration exhibited high percentage inhibition (77.82%) comparable to the standard drug at 91.28%, and reduction in paw thickness was also observed in the carrageenan model in a dose-dependent manner respectively. This study showed that CAELE at different concentrations showed anti-inflammatory activity in diabetic conditions.

Effects of sub-chronic oral administration of hydromethanolic stem extract of Costus afer Ker Gawl. (Costaceae) on body weight, relative organ weight (ROW) and histopathology of selected organs in rats

Adverse effects of plant extracts on body weight, relative organ weight and histopathology are important indicators of toxicity. The aim of this study was to evaluate the acute and sub-chronic toxicity of the hydromethanolic stem extract of Costus afer Ker Gawl. (Costaceae). OECD (2008) Guideline 425 was used to evaluate oral acute toxicity of the extract. Sub-chronic oral administration of the extract on body weight, relative organ weight (ROW) and histopathology of selected organs in Wistar rats were evaluated using OECD 1995 guideline 407. Forty Wistar rats of both sexes were divided into 4 groups. Rats in control group (Group I) received 1 ml/kg/day distilled water while Groups II, III and IV rats received 250, 500, and 1000 mg/kg/day of the extract respectively for 28 days. All treatments were administered orally. The rats were sacrificed under light halothane anaesthesia on the 29th day and the target organs were harvested, weighed and examined macroscopically for any morphological changes and microscopically for any lesions. There were no significant changes in mean body weights of rats and relative organ weights of selected organs in the extract treated groups when compared with the control group (distilled water). Although histological features of the brain, heart, stomach mucosa, lungs, spleen, ovaries and uterus in the extract treated groups were similar to those of control, slight to moderate renal and hepatic necrosis and necrosis of secondary spermatogenic cells at doses of 500 mg/kg and above of the extract were observed in the kidneys, liver and testes respectively. Caution should be exercised on sub-chronic administration of this extract as it may be toxic to the kidneys, liver and testes.

Costus afer Ker Gawl (Costaceae): A Review on Its Medicinal uses with Focus on Potential Anti-Inflammatory Effect

More than 80% of the population in Africa by the World Health Organization (WHO) leans on endogenous knowledge to solve their primary health care problems. In this study, we examined the relevance of Costus afer Ker Gawl, a plant called ginger lily, spiral ginger or bush cane. It is believed to be used in traditional medicine practice (TMP) to treat and manage many conditions including diabetes mellitus, stomach ailments, arthritis, inflammation. These alleged traditional incited large researchers to conduct studies on the plant to amass scientific evidence. However, these results are sparse, and thus, an inventory through the present search using online search engines such as Google Scholar, PubMed, Science Direct, Web of Science, Scopus and Chemical Abstracts for the period from 1990 to 2021; provides a bibliographic actualization on the plant, taking into account its traditional uses, phytochemical and nutritional constituents, pharmacological activities and toxicological effects. The online search included the use of the keywords, "Costus afer Ker-Gawl" or "Costus afer". It should be noted that the stem and leaves of the plant contain consistent amounts of micronutrients and macronutrients. The leaves, stem, rhizomes of C. afer contain several steroidal sapogenins, aferosides, dioscin and paryphyllin C and a flavonoid glycoside, kaempferol-3-O- \(\alpha\)-L-rhamnopyranoside. Experimental studies on various parts of the plant have shown biological activities such as anti-hyperglycemic, hepatocellular protection, cardioprotection, nephroprotection, CNS depressant, analgesic, antiarthritis, antibacterial and antioxidant. This wide range of biological properties of Costus afer Ker Gawl would be largely attributed to the essential oil compounds such as Sabinene, \(\beta\) -pinene and \(\beta\) -caryophyllene which are among the major compounds of this plant. Based on these obvious data, it is concluded that the plant could be used as an alternative and complementary therapy for many diseases related to oxidative stress so will guide us future research on the use of Costus afer Ker Gawl as an anti-inflammatory.

Protective Effect of Costus afer Aqueous Leaf Extract (CALE) on Low-Dose Heavy Metal Mixture-Induced Alterations in Serum Lipid Profile and Hematological Parameters of Male Wistar Albino Rats.

The present work investigated the protective effects of Costus afer Ker Gawl. aqueous leaf extract (CALE) on lipid profile and hematological changes induced by exposure to low-dose heavy metal mixture in male albino rats. The experimental animals were divided into six weight matched groups. The normal (group 1) and toxic (group 2) controls received deionized water and metal mixture (20 mg/kg PbCl2, 1.61 mg/kg CdCl2, and 0.40 mg/kg HgCl2), respectively. Test rats in groups 3, 4, and 5 were treated with metal mixture and CALE (750, 1500, and 2250 mg/kg, respectively), and group 6 received metal mixture and ZnCl2. All treatments were administered through oral gavage for 12 weeks. LDHMM caused a marked increase (p < 0.05) in cholesterol, triglyceride, low-density lipoprotein (LDL), and very low-density lipoprotein (VLDL) levels and a decrease in high-density lipoprotein (HDL), percentage body weight gain, and feed and fluid intake. Also, a significant decrease in RBC, Hb, and PCV, a significant increase in WBC, and no significant increase in platelet PLT were observed in the metal mixture-treated group. But in CALE treated groups, their levels were found to attain almost normal values as found in normal control which is also similar to the zinc-treated group. Costus afer may hold a promise in improving lipid profile and hemodynamic picture in cardiovascular diseases.

EFFECT OF SUB-CHRONIC ORAL ADMINISTRATION OF HYDROMETHANOLIC STEM EXTRACT OF COSTUS AFER KER GAWL. (COSTACEAE) ON LIVER AND KIDNEY FUNCTIONS IN WISTAR RATS

The liver and the kidneys are two very important organs in the body and they are responsible for the metabolism and excretion of drugs respectively amongst several other functions. Severe adverse effects on these organs can lead to organ dysfunction or failure and a consequential effect on wellbeing and can even be life-threatening. This study investigated the effects of hydromethanolic stem extract of Costus afer Ker Gawl. (Costaceae) on liver and kidney function indices and the histopathology of the organs in Wistar rats. Serum liver enzymes which include: alanine amino transferase (ALT), aspartate amino transferase (AST) and alkaline phosphatase (ALP), total protein and albumin as well as serum urea, creatinine, sodium ions, potassium ions, chloride ions, bicarbonate ions were evaluated in biochemical studies. Sections of the liver and kidneys appropriately treated were examined microscopically for pathological lesions.There were decreased serum levels of ALT and ALP, but serum levels of AST increased at 500 and 1000 mg/kg doses. Serum levels of total protein (TP) and albumin concentration as well as urea and creatinine serum levels were not significantly (p&gt;0.05) affected. However, histological examination of the liver and kidneys revealed slight to moderate hepatic necrosis and slight tubular necrosis respectively especially at 500 and 100 mg/kg doses of the extract. The results showed that the extract may be harmful to the liver and to a lesser extent the kidneys on prolonged administration and therefore it should be used with caution in such instances.

The protective effect of Costus afer Ker Gawl aqueous leaf extract on lead-induced reproductive changes in male albino Wistar rats.

Introduction:Lead is a multiple organ toxicant and an oxidative-stress inducer. The effect of Costus afer on metal- induced male reprotoxicity has not been previously carried out, hence this study. The present study investigates the protective effect of Costus afer aqueous leave extract on lead- induced reproductive damages in male albino Wistar rats.Methods:Adult male albino Wistar rats were weighed and separated into five groups of five rats each. Groups 1 & 2 served as normal and toxic controls receiving deionized and leaded (CH3COO)2Pb.3H2O and water respectively. Groups 3, 4 and 5 were given 750, 1500 and 2250mg/kg of Costus afer orally, respectively while receiving Pb2+ water ad libitum for 28 days.Results:The reproductive and antioxidant parameters obtained from the result served as scientific evidence in the study. The result showed non-significant changes in the absolute and relative weights of epididymis and testes in the Pb Group versus the control. Significant increases were recorded in the sperm analysis, blood lead (7.9±1.02; 1.1±0.01) level (BLL), luteinizing hormone (LH) (8.5±1.4:5.5±0.4), and a decrease in follicle stimulating hormone (FSH) (4.5±2.6:6.5±1.65), with non-significant changes in testosterone (TET) (1.3±0.00:1.6±0.2) in the Pb group compared to the control.Conclusion:The treatment with Costus afer exhibited dose-dependent significant changes in testicular oxidative stress, hormonal, sperm analysis and histopathological changes induced by lead. Aqueous leaves extract of Costus afer may be protective against lead induced testicular damage.

Investigatory Study of Long Term Doses of &amp;lt;i&amp;gt;Costus afer&amp;lt;/i&amp;gt;, Snail Slime, and Their Combination with a Standard Pharmaceutical Drug on Blood Glucose Level of Alloxan Induced Swiss Albino Rat

The Plant, Costus afer Ker Gawl. belongs to the family of Costaceae and has various uses where they exist. Their use in folk medicine and phytomedicine is in the treatment and management of variety of human ailment, like diabetes mellitus, abdominal problems etc. The search for new antidiabetic therapies has become increasingly urgent due to the development of adverse effects and resistance by the chemically synthesized drugs on one hand and effectiveness with low cost of the plant materials on the other hand. The investigations carried out is to determine the long term effects of Costus afer leaf methanol extract, snail slime and the combined Costus afer and snail slime extracts on blood glucose levels of alloxan induced diabetic Swiss albino rats treated orally for 21 days on graded dose of (100 mg/kg and 300 mg/kg). From the determination, the snail slime showed positive effect on blood glucose lowering level but less effective when compared with similar dose of the Costus afer leaf methanol extract. The investigation indicated that there was 103 mg/dL and 87 mg/dL blood glucose reduction for the low dose of Costus afer and Snail slime respectively while the standard hypoglycemic drug (Glibenclamide, 5 mg/kg) used for comparison yielded a blood glucose level reduction of 103 mg/dL. Similarly, the high dose used in the study gave a blood glucose reduction of 99 mg/dL and 95 mg/dL for Costus afer leaf methanol extract and Snail slime respectively. The results obtained when alloxan induced rats was treated with C. afer leaf methanol extract, Snail slime extract, and combined C. afer and snail slime extracts was analysed using Statistix 8.0 American version. The result showed a dose dependent fashion and the difference obtained from the compared results was statistically significant at p 1]. Still to that, medicinal and pharmacological activities of medicinal plants are often attributed to the presence of the so called secondary plant metabolites. Hence this regenerative capacity of snail slime and the fact that diabetes is characterized by damage of the pancreatic beta cells, may give credit to the hypoglycaemic effect observed in Costus afer methanol leaf extract and snail slime for possible drug formulation for anti-diabetic remedy. Our findings may approve snail slime which is insoluble in both acid and alkaline medium, to act as a carrier of chemical and biological nanoparticles for medical and pharmaceutical use.

Nephroprotective and antioxidant effect of aqueous leaf extract of Costus Afer Ker gawl on cyclosporin-a (Csa) induced nephrotoxicity

BackgroundOxidative stress (OS) has been linked to the pathology of a variety of chronic and degenerative diseases. Medicinal plants contain bioactive compounds which are capable of preventing and fighting these diseases. The nephroprotective and antioxidant properties of the aqueous leaf extract of Costus afer (C.afer) against cyclosporine A CsA - induced nephrotoxicity in Wistar albino rats were investigated.MethodsSix groups of five weight-matched animals each, were used for the study. The first and second groups served as normal and toxic control and were given olive oil and CsA (50 mg/kg b.w.) orally respectively while groups 3, 4, 5 and 6 ingested 375, 750 and 1125 mg/kg b.w. aqueous leaf extract and 100 mg/kg b.w. of the Silymarin respectively one hour prior to administration of CsA 50 mg/kg b.w.ResultsTreatment with C. afer extract at doses of 375, 750 and 1125 mg/kg prevented the CsA induced nephrotoxicity and oxidative impairments of the kidney, as evidenced by a significantly (p < 0.05) reduced plasma creatinine, BUN, K+ and renal malondialdehyde (MDA). Furthermore, all the doses were able to induce a significant increment (P < 0.05) of renal levels of glutathione (GSH) and plasma superoxide dismutase (SOD) activity, catalase(CAT), glutathione-S-tranferase (GST), serum electrolytes (Na+ and HCO3−), body and kidney weight. The nephroprotective effects of C.afer extract were confirmed by a reduced severity of renal cellular damage.ConclusionAqueous leaf extract of C.afer has a protective role against CsA- induced nephrotoxicity probably mediated through its antioxidant properties.
