Abstract Sequestration of Plasmodium berghei ANKA-infected erythrocytes occurs in BALB/c mice as characteristic of  Plasmodium falciparum infection in humans. Animals’ bile has been widely used for centuries in Traditional Chinese Medicine. Goat bile has been used in healing infectious and non-infectious diseases; however, no report on the use of goat bile against malaria infection and sequestration. The purpose of this study was to analyze the correlation between parasitemia and sequestration in the liver of P.berghei ANKA-infected BALB/c mice treated with goat bile. This research was an in vivo experimental study using the post-test control group design. The male BALB/c mice aged ± 6 weeks, body weight 20-25 g were used. The mice were divided into five groups where Group 1-3 were mice treated with goat bile 25%, 50%, and 100%, respectively. Group 4-5 were negative (sterile water) and positive controls (DHP). Parasitemia was observed daily from each mouse and the number of sequestered infected erythrocytes on the endothelium of sinusoids. The data were analyzed using t independent test. Antimalarial activity of goat bile was shown by the lower parasitemia in goat bile-treated mice compared with the negative control. The average number of sequestration was goat bile concentration-dependent manner. The higher the concentration, the lower the number of sequestration. Sequestration was correlated with parasitemia (p=0,0001). Sequestration of P.berghei ANKA-infected erythrocytes correlated with parasitemia, and was goat bile concentration-dependent manner. Keywords: Malaria, parasitemia, sequestration, goat bileCorrespondence: [email protected]

Abstract Goat bile has been used by some Indonesian people to treat malaria and increase their stamina. This study aimed to prove whether goat bile toxic or not in BALB/c mice and to verify the antimalarial activity of goat bile at various concentrations in mice infected with Plasmodium berghei ANKA. Acute toxicity test was performed using twenty male BALB/c mice with an average body weight of 25 grams, which were divided into four groups. Mice were given 25%, 50%, and 100% goat bile, respectively, while negative control was given distilled water. Any change in weight, odor, color, agitation, appearance, color of urine and feces, coma, and death, were recorded. A different set of mice were infected with P. berghei ANKA. This study conducted using the posttest only control group design with four treatments and five replications. A four day-treatment of goat bile was given by oral gavage to find out its effect on parasitemia level. Infected mice were divided randomly into 4 groups, where the GBNeg group as negative control was given only distilled water. The GB25, GB50, and GB100 groups were treated with 25%, 50%, and 100% goat bile, respectively. The parasitemia was observed daily on Giemsa-stained tail blood smears of each mice. No death or other sign of toxicity was found in goat bile-treated mice. Goat bile showed anti-malarial activity. The parasitemia in all goat bile treated groups was lower compared with the negative control group. The ED50 of goat bile against the growth of parasite was 48,55 %. Goat bile is a potential source of new antimalarial therapies. Further investigations are recommended to yield new anti-malarial drug candidates. Keywords                :    Goat bile, parasitemia, Plasmodium berghei ANKA, ED50Correspondence     :    [email protected]

Background. Malaria is a major health concern in the world in general and developing countries in particular. Nowadays, the control of malaria has ended up steadily more complex due to the spread of drug-resistant parasites. Medicinal plants are the verifiable source of compelling antimalarial drugs. The present study was aimed to assess the in vivo antimalarial activity of leaf latex of A. melanacantha against Plasmodium berghei in mice. Methods. Acute oral toxicity study of the leaf latex was assessed in mice up to a dose of 2,000 mg/kg. A four-day suppressive model was utilized to investigate the antimalarial activity of the plant. Three extract doses, 100, 200, and 400 mg/kg/day, doses of the plant leaf latex, chloroquine, 10 mg/kg (positive control) and distilled water, and 10 mL/kg (negative control) were administered to mice. Percent parasitemia suppression, packed cell volume, mean survival time, body weight, and rectal body temperature were used to determine antimalarial activity. Results. Test groups treated with 100, 200, and 400 mg/kg of the latex showed a significant parasitemia suppression in dose dependent manner compared to the negative control with an IC50 of 22.63 mg/ml. Mice treated with 100, 200, and 400 mg/kg have shown parasitemia suppression of 14.86%, 29%, and 43.2%, respectively. The chemosuppression was significant ( P < 0.05 ) at all doses compared to the negative control. Similarly, mice treated with 100 mg/kg, 200 mg/kg, and 400 mg/kg have shown a significant survival time compared to the negative control. At the same time, weight loss reduction was observed within the test groups treated with 100 mg/kg and 200 mg/kg of the latex while the test groups treated with 400 mg/kg had showed almost no weight loss reduction. The latex also reversed the PCV reduction significantly ( P < 0.05 ) at 200 mg/kg and 400 mg/kg doses and prevented rectal temperature dropping significantly ( P < 0.05 ) at all doses. Conclusion. The leaf latex of A. melanacantha has shown significant antimalarial activity against P. berghei in mice supporting the genuine traditional antimalarial usage of the plant.

Ethnopharmacological relevance: Cymbopogon citratus (DC.) Stapf (Poaceae) is a medicinal plant known for its antimalarial, antipyretic and antifatigue activities in Cameroonian folk medicine. Aim of the study: The aim of this work was to evaluate the prophylactic antimalarial effects of the decoction prepared from the leaves of Cymbopogon citratus on Plasmodium berghei ANKA infection in mice and investigate its action on haematological and serum biochemical status. Materials and methods: Swiss mice were treated with Cymbopogon citratus leaf decoction (25, 50, 100 and 200 mg/kg) and later inoculated with Plasmodium berghei ANKA. The prophylactic antimalarial activity of the decoction was evaluated by determining the parasitaemia, percentage chemosuppression, body weight, body temperature, food and water intake in pretreated parasitised mice. The possible ameliorative effects of the decoction on malaria associated haematological and serum biochemical changes were also assessed. Results: The decoction exhibited a prophylactic activity of 85.32% and its chemotherapeutic effects ranged from 56.88 – 85.32% with maximum effect observed at the highest experimental dose. It significantly inhibited parasitaemia (P < 0.001) compared to the negative control group. Interestingly, treatment of parasitised mice with the decoction significantly restored the malaria modified haematological and biochemical status compared with distilled water-treated parasitised mice. Conclusion: The results of this prophylactic assay indicated that Cymbopogon citratus decoction has antimalarial effects and normalised haematological and serum biochemical aberrations generated by malaria. Hence, Cymbopogon citratus represents a promising source of new antimalarial agents.

Background. Despite a substantial scientific progress over the past two decades, malaria continues to be a worldwide burden. Evergrowing resistance towards the currently available antimalarial drugs is a challenge to combat malaria. Medicinal plants are a promising source of new drugs to tackle this problem. Thus, the present study aimed at evaluating the antiplasmodial activity of Terminalia brownii in Plasmodium berghei infected mice. Methods. A 4-day suppressive test was employed to evaluate the antimalarial effect of 80% methanol and aqueous bark extracts of T. brownii against P. berghei in Swiss albino mice. Results. The in vivo acute toxicity test indicated that both extracts of T. brownii did not cause mortality. The 4-day early infection test revealed that the 80% methanol and aqueous extracts exhibited a significant inhibition of parasitemia p<0.001 compared to negative control. The maximum level of chemosuppression (60.2%) was exhibited at 400 mg/kg dose of 80% methanol extract. Moreover, the 80% methanol extract showed a significant p<0.001 attenuation of anemia associated with infection in a dose-dependent manner. The aqueous extract, on the other hand, exhibited a percent inhibition of 51.1% at the highest dose (400 mg/kg/day). Conclusion. The present study indicated that hydromethanolic and aqueous bark extracts of T. brownii possess a promising antimalarial activity, with higher effect exhibited by the hydromethanolic extract.

Antiplasmodium activity test of methanol extract of leaves of kelwih (Artocarpus camansi) was carried out in vivo in mice (Mus musculus) Balb / c infected with Plasmodium berghei. The purpose of this study was to determine the effective dose of methanol extract of leaves of kelwih as antiplasmodium. Antiplasmodium activity test was carried out in vivo in Balb / c mice that had been infected with Plasmodium berghei. Parameters observed were parasite growth, and parasite inhibition. After the administration of methanol extract of leaves of kelwih and as many as 30 mice were grouped into 5 treatment groups which were given extract doses of 1, 25, 50, 75, and 100 mg / kg BB and one negative control group (without the administration of methanol extract of kelwih leaves). Observations were carried out for 7 days, starting from day 0 (before treatment), 4 days during treatment and 2 days after treatment. The data obtained were analyzed statistically ANOVA using the Kruskal-Wallis H test and continued with Mann-Whitney U test. The results showed that the lowest parasite growth (1.636%) was obtained from the group dose of 100 mg / kg BB, the largest parasite inhibition (72.832% ) also produced by a group dose of 100 mg / kg BB. An extract is said to have positive antimalarial activity if it can reduce parasitemia by 30% or more. A dose of 100 mg / kg body weight produces parasitic growth values, and parasite inhibition is significant to the control (p <0.05). So, from the explanation above, it can be concluded that giving a dose of 100 mg / kg BB of methanol extract of leaves of kelwih has potential activity as an antimalarial.

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.

Introduction: Quercetin is a flavonoid compound found in many medicinal plants. Antispasmodic effect of quercetin has been reported in ileum and uterus smooth muscles but not in bladder. Therefore, the objective of this research was to investigate relaxant effect of quercetin in rabbit isolated bladder. Methods: Male rabbit was asphyxiated with carbon dioxide and then sacrificed. The whole bladder was dissected out and placed in oxygenated Tyrode’s solution. Isolated bladder was cut into longitudinal strips and placed in an organ bath for contraction studies. Contractions were induced with KCl (20mM), acetylcholine (5μM) and electrical field stimulation (EFS). Full inhibitory concentration–response curve was constructed for quercetin following addition of above spasmogens. Quercetin was added into the organ bath with 2 fold increments in concentration until maximum response was achieved. Nifedipine was used as positive control group and equivalent volume of quercetin vehicle (water + DMSO) was used as negative control group.Results: Quercetin (4 μg/mL to 640 μg/mL) in a concentration dependent manner inhibited isolated bladder strips contracted by KCl (IC50=159±25 μg/mL), acetylcholine (IC50=43±9.1 μg/mL) and EFS (IC50=38±9.3 μg/mL). In the highest used concentration, quercetin completely removed contractile responses to KCl, acetylcholine and electrical filed stimulation (EFS). Nifedipine totally inhibited KCl response (IC50=115±36 ng/mL) but only partially inhibited acetylcholine and EFS responses. Conclusion: These results confirm the relaxant effect of quercetin on rabbit bladder and if similar effects are seen in human studies, then quercetin would be a suitable drug candidate to be investigated for bladder incontinence.

Background. Malaria is one of the most critical diseases causing about 219 million cases worldwide in developing countries. The spread and development of resistance against chemical antimalarial drugs is one of the major problems associated with malaria control. The present study was to investigate the antimalarial efficacy of ethyl acetate extract and one fraction of Bidens pilosa in vivo in order to support the usage of this plant by traditional healers to treat malaria. Methods. The extracts were prepared by maceration of B. pilosa leaf powder in ethyl acetate. The liquid filtrate of the extract and the best in vitro antiplasmodial fraction using HPLC were concentrated and evaporated using a rotavapor under vacuum to dryness. The antimalarial activity of B. pilosa plant products were evaluated in vivo against Plasmodium berghei infected mice according to the Peter and Rane test. The antimalarial efficacy of the a selected crude extract (ethyl acetate extract) was evaluated at 125, 250, and 500 mg/kg, while a selected fraction from ethyl acetate extract (fraction 12) was evaluated at 62.5 and 125 mg/kg. Blood from experimental animals was collected to assess hematological parameters. Results. The crude extract of ethyl acetate and fraction 12 demonstrated 100% in vivo parasite suppressive activity at doses of 500 mg/kg and 125 mg/kg, respectively, for the crude extract and fraction 12. The mice treated with 250 and 500 mg/kg had their parasitemia (intraerythrocytic phase of P. Berghei) drop considerably, disappearing by the 8th day in mice receiving 500 mg/kg. The ethyl acetate extract of B. pilosa, fraction 12 showed an even higher antiplasmodial activity. By the 5th day of the experiment, the treatment led to a modification of hematological parameters in mice. The chloroquine (5 mg/kg), fraction 12 (125 mg/kg), and the crude extract (500 mg/kg) groups all survived the 30 days of the experiment, while the negative control group registered 100% of the deaths. Conclusion. This study scientifically supports the use of Bidens pilosa leaves in the traditional treatment of malaria. However, the mode of action and in vivo toxicity of the plant still need to be assessed.

Failure of the efficacy of antimalarial drugs is recognized in different classes of medicines for treating malaria, which urges the need for new drugs. This study tried to check the in vivo antimalarial activity of the root extracts of Acanthus polystachyus Delile against Plasmodium berghei–infected mice. The study revealed that the methanolic crude extract of the root of Acanthus polystachyus Delile showed significant ( P < .01) parasitemia suppressive activities in both models compared with the negative control. Parasitemia suppressive activities were 25.26%, 33.46%, and 51.48% in a 4-day suppressive test and 23.31%, 31.20%, and 43.54% in prophylaxis test at 100, 200, and 400 mg/kg of the extract, respectively, as compared to the negative control. Besides, the extract increases mean survival time significantly in all tested doses in a 4-day suppressive test, but in the prophylaxis model, only mice treated with 200 and 400 mg/kg significantly lived longer. Based on this finding, the root of Acanthus polystachyus Delile has strong antimalarial activity, which may be a good candidate for new antimalarial agents.
