The study determined if administration of Vernonia amygdalina and Carica papaya plants provides synergistic effects in ameliorating plasmodium infection in mice. Thirty mice (17.88–25.3 g) were divided into 6 groups of 5 mice each. Group 1 was normal control, while groups 2–6 were intraperitoneally inoculated 2.5 × 107 Plasmodium berghei parasitized red blood cell, followed by daily administration of 350 mg/kg aqueous leaf extracts after establishment of infection. Group 2 was disease control, while group 6 was treated with standard drug for four consecutive days. The results showed significant (P<0.05) reduction in percentage of parasite load between the infected treatment groups and disease control group at day 3 after infection, which remained consistent until the end of the experiment. All infected treated groups showed significant (P<0.05) increases in RBC and PCV recovery compared to the disease control, with the exception of WBC. There was insignificant (P>0.05) change in mean body weight of all treated groups except in disease control group. Histological studies of the infected mice indicate recovery of hepatic cells from congested black pigmentation. The reduction in parasite load and recovery of hepatic cell damage/hematological parameters were induced by these plant extracts. This highlighted the important usage of the plant in traditional remedy of malaria infection.

Objective. The study was designed to evaluate pharmacological potential of hydroalcoholic leaves extract of Chrozophora tinctoria intended for wound healing in diabetic rats’ model. Methods. The method used to evaluate the pharmacological potential of hydroalcoholic leave extract was physical incision rat model. In this model, cutting of the skin and/or other tissues with a sharp blade has been made and the rapid disruption of tissue integrity with minimal collateral damage was observed shortly. Animals used in the study were divided into four groups that consist of six animals in each group. Group I serves as normal control, Group II serves as disease control, Group III was used as standard treatment (Povidone iodine 50 mg/kg b.w.), and Group IV was used for test drug (C. tinctoria 50 mg/kg b.w.). Result. The hydroalcoholic leave extract of Chrozophora tinctoria has been significantly observed to heal the wound (98%) in diabetic rats within 21 days, while standard drug (Povidone iodine) healed the wound about 95% in the same condition. The oral dose (50 mg/kg b.w.) of Chrozophora tinctoria was also found to improve the elevated blood glucose level in comparison to disease control group, which increased after the oral administration of Streptozotocin. Conclusion. The Chrozophora tinctoria has significant wound healing potential in the animal having physically damaged tissue in diabetic condition.

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.

Plant-based products, believed to be less toxic have been employed as hepatoprotective agents in recent times. Polyherbal therapy is reported to have therapeutic benefits over single herb therapy. Allium sativum and Carica papaya are two known plants used traditionally for the treatment of liver related diseases. Thus, in this study, the hepatoprotective and antioxidant potential of hydroethanol extracts of Allium sativum cloves (Garlic) and Carica papaya (Pawpaw) leafs (singly and combined) against CCl4-induced toxicity in rats was evaluated. Thirty male albino rats used were classed into six (groups A- F) groups of five rats each and treated (orally) for 14 days. Group A- rats + distilled water (negative control); Group B- rats + CCl4 in olive oil (positive control); Group C- rats + 200 mg/ kg-day combined extract of A. sativum and C. papaya (1: 1 ratio); Group D- rats + 200 mg/ kg-day extract of A. sativum; Group E- rats + 200 mg/ kg-day extract of C. papaya; Group F- rats + 100 mg/kg bw of silymarin. CCl4 induce hepatotoxicity was characterized by an upsurge (P<0.05) in serum Alkaline Phosphatase (ALP), Aspartate Aminotransferase (AST) and Alanine Transaminase (ALT) activities, and total bilirubin. Also, CCl4 administration led to a substantial reduction (P<0.05) of reduced glutathione (GSH), Glutathione peroxidase (GPx), superoxide dismutase (SOD) and catalase (CAT) activities and an increase (P<0.05) in lipid peroxidation (MDA) in the liver tissue. However, treatment with hydroethanol extract of A. sativum and C. papaya prevented the CCl4 induced lipid peroxidation and returned the altered marker enzymes of serum and antioxidant enzymes level to near normal. The extracts of both plants demonstrated significant antioxidant and hepatoprotective activity as reflected by the results. Comparatively, the combined extract gave the most promising antioxidant and hepatoprotective potential, which may be due to positive synergistic effects of both plants over either plant used singly, thereby vindicating the use of polyherbal remedy over a single herb.

Abstract BackgroundRecently, artemsinin-resistant malaria strains and clinical cases have appeared in Southeast Asia. Reportedly, there are malaria mutants in Africa that are resistant to artemisinin and its derivatives. Thus, it’s imminent to develop new antimalarial drugs. Brucea javanica is an effective antimalarial drug recorded in Chinese traditional medicine, which has been widely used in the folk for hundreds of years. Brusatol is the main active constituent of Brucea Javanica, thus we studied the effects of brusatol on prevention of malaria infection in vivo. MethodsTo determine the antiplasmodial activity of brusatol, a four-day suppressive test was used by dividing 56 mice into 7 groups of 8 mice each and given 4mg/kg, 3mg/kg, 2mg/kg, 1mg/kg, 0.5mg/kg of brusatol, the standard drug ((artesunate of 140 mg/kg) and the vehicle (normal saline). The best effective dose was used in the following test. The effects of brusatol to plasmodium berghei transcription were tested through RNA-seq and the results were confirmed by RT-qPCR. We also explored the expression of TNF -α, IFN-γ, IL-4, IL-12 to evaluate antimalarial mechanism of brusatol to host by ELISA.ResultsThe results showed that brusatol effectively inhibited plasmodium berghei infection, the best effective dose was 2mg/kg, and the side effects of brusatol to liver and kidney were slight and reversible. The expressions of GSK3β, ATP6A, ATP6B, ATP6M, MSP-2, EMP1, CTCS in plasmodium were significantly lower after brusatol treatment compared with control, while the expression of AMA-1 was significantly increased. The serum concentrations of IFN-γ, TNF-α and IL-4 in artesunate and brusatol group decreased significantly compared with the control group, while there was no statistical difference of the serum concentrations of IL-12.ConclusionsTaken together, these results demonstrated brusatol could be a priority candidate for antimalarial medicine development.

Extracts of Alstonia boonei and Carica papaya are used in herbal medicine for the treatment of malaria. This work investigated the phytochemical, antioxidant, and antimalarial effects of hydromethanolic extracts of Alstonia boonei and Carica papaya. A four-day chemosuppressive test was conducted to assess the ability of the extracts to prevent establishment of infection. Three doses of the extracts were administered—100, 200, and 400 mg/kg bw—prior to Plasmodium berghei challenge. Change in body weight, parasitemia, packed cell volume (PCV), and mean survival time was determined. A three-day curative test was also carried out on Plasmodium berghei-infected mice to determine the effects of the plant extracts (200 mg/kg bw) on parasitemia and biochemical indices of liver and kidney functions, lipid metabolism, and oxidative stress. The study revealed that the extracts possessed phenolic compounds (34.13 ± 1.90 mg GAE/g for Alstonia boonei and 27.99 ± 1.46 mg GAE/g for Carica papaya) and flavonoids (19.47 ± 1.89 mg QE/g for Alstonia boonei and 18.24 ± 1.36 mg QE/g for Carica papaya). In vitro antioxidant activity measured as total antioxidant power, total reducing power, and DPPH radical scavenging activity showed that the extracts possessed higher antioxidant activity than the reference compounds. The outcome of the chemosuppressive test revealed that whereas Plasmodium berghei-infected mice had high parasitemia, decreased mean survival time, exhibited loss of weight, and had low PCV, treatment with the extracts reversed the effects in a concentration-dependent manner. Similarly, the curative test revealed that the extracts significantly suppressed parasitemia compared with the malaria negative control group. This was mirrored by reversal of indices of hepatic toxicity (AST, ALT, and ALP levels), nephropathy (urea and creatinine levels), oxidative stress (SOD, CAT, GPx, GSH, and lipid peroxides), and dyslipidemia (TC, HDL, and TG levels and HMG-CoA reductase activity) in infected but treated mice compared with negative control. Put together, the results of this study demonstrate that the extracts of Alstonia boonei and Carica papaya possess antimalarial properties and are able to ameliorate metabolic dysregulations that characterize Plasmodium berghei infection. The phytoconstituents in these extracts are believed to be responsible for the pharmacological activity reported in this study.

Trianthema triquetra Rottl. Ex.Willed (T. triquetra) is a medicinal plant that belongs to the family Aizoaceae. The plant has been used traditionally as fodder, as a remedy for chronic ulcer, fever, and healing wounds. Therefore, the present study was intended to investigate the anti-ulcer ability of different fractions of T. triquetra to verify its folklore use in ulcer cure. Acute oral toxicity of all the fractions of T. triquetra was evaluated at a dose of 2g/kg b.wt. Anti-ulcer potential of nbutanol (TTB), chloroform (TTC), ethyl acetate (TTEA) and aqueous (TTA) fraction of crude methanolic extract of T. triquetra was assessed by using ethanol- induced gastric ulcer model in rats. Omeprazole at a dose of 20 mg/kg b.wt. was used as standard drug. After 1 hour of administration of all the fractions of T. triquetra, at a dosage of 300mg/kg b.wt., the gastric ulcer was induced in all animals by administering absolute ethanol (1mL/animal) orally except normal control group. After an hour, all the rats were sacrificed. Ulcer index, % age of ulcer inhibition, gastric pH, gastric volume, total acidity, gastric wall protein, gastric wall mucus and histopathology of the stomach wall of rats were assessed. All fractions of T. triquetra showed a substantial decrease in ulcer index and improvement in percentage inhibition compared to the disease control group. There was a rise in the amount of gastric wall mucus content, total protein content, gastric pH and a decrease in gastric volume and total acidity. Histopathological studies showed severe mucosal injury, leucocyte infiltration and edema in the disease control group compared to omeprazole and plant fractions treated animal groups. The present work encourages the conventional use of T. triquetra in the cure of ulcers.

Background and Objective: Rheumatoid arthritis (RA) is an autoimmune disease characterized by failure of spontaneous resolution of inflammation with lifetime perseverance, becoming principal cause of inactivity. Many conventional therapies are in use but the side effects associated with them are equally problematic. Therefore an urge to explore advanced therapeutic approaches with least adverse events has seeded the idea of discovering newer herbal drugs and their respective constituents in management of RA. The current research explores anti-arthritic activity of Terminalia catappa fruits hydroalcoholic extract in CFA induced Wistar rats. Methods: The fruits were obtained, washed, dried and processed to obtain hydroalcoholic powdered extract which was dissolved in water and given orally to the rats. Wistar rats of either sex were used in the study. The animals were injected with 0.1 ml of complete freund’s adjuvant (CFA) in footpad of left hind paw. The treatment was initiated from day 0 by oral dosing of Terminalia catappa fruit extract in doses of 40 mg/kg and 80 mg/kg followed by CFA administration to day 21 and behavioral, hematological parameters besides histopathological screening were assessed simultaneously. Results: The arthritic symptoms were observed to gradually decrease in treatment groups when compared against disease control groups. The parameters like body weight and pain latency were increased whereas paw volume and arthritic score were found to significantly decrease in treatment groups as compared to disease control group. The hematological parameters were also modified and were studied in treatment groups. The histopathological estimation depicted extent of damage in joint tissue of diseased rat comparable to normal, standard and combination therapy group. Conclusion: The fruits possess anti-arthritic properties and significantly reduced paw volume, arthritic score and increased pain threshold and body weight gain besides theory hematological effects like increase in Hb and RBC and decrease in WBC, platelets and ESR levels simultaneously. The histopathological estimation confirmed decreased deterioration of joint tissue in treatment groups as compared to disease control group hence proving to be an emerging therapeutic option in management of RA.

Objective: This study was undertaken to screen the effect of administration of various doses of hydroethanolic extract of unripe fruit of Carica papaya L. (HEECP) against Dalton’s ascitic lymphoma (DAL) in Swiss albino mice.Methods: DAL cells were injected intraperitoneally (1×106 cells) to each mouse and divided into various groups. The animals were treated with various doses (200 mg/kg and 400 mg/kg) of HEECP. A standard drug (5-fluorouracil, 20 mg/kg/day) was also used. The animals were evaluated for hematological and biochemical parameters and were compared with the same parameters in the standard by collecting blood from a retro-orbital blood vessel of mice. Results: The life spans of the animals were increased. In the DAL tumor control group, the average life span of animals was found to be 45% whereas, 200 and 400 mg/kg of test drug showed increase in life span to 67% and 75%, respectively. Platelets count was significantly (p<0.001) decreased in cancer control group and was brought back to normal after treatment. Conclusion: These observations suggest that the extract possesses antineoplastic effect against DAL.

Visceral leishmaniasis (VL) is a vector-borne parasitic disease targeting tissue macrophages. It is among the most neglected infectious diseases. As available therapeutics for treatment of this disease have many side effects, there is a need for safer alternatives. One of the immunopathological consequences of active visceral leishmaniasis is suppression of protective T-helper (Th)-1 cells and induction of disease-promoting Th-2 cells, and thus the treatment of VL relies on immunomodulation. In the current study, herbal drugs derived as whole-plant extracts of Asparagus racemosus and Withania somnifera were used to treat Leishmania donovani-infected BALB/c mice. Keeping the scenario of immunosuppression during VL in mind, the potential of these drugs in the restoration of murine Th-1-type protective immune responses was evaluated. To investigate the propensity of these drugs to treat VL, liver parasite load, delayed-type hypersensitivity responses and parasite-specific immunoglobulin levels were studied. Various biochemical and haematological tests were also carried out. A positive-control group used the standard drug treatment of sodium stibogluconate. Treatment of infected mice with A. racemosus and W. somnifera in combination at the higher dose of 200 mg (kg body weight)−1 not only resulted in a successful reduction in parasite load but also generated protective Th1-type immune responses with normalization of biochemical and haematological parameters, suggesting their potential as potent anti-leishmanial agents.

The rapid emergence and spread of Plasmodium falciparum resistance to Artemisinin derivatives and all the conventional antimalarial drugs necessitates the importance of ethnobotany, resulting in need to study the antiplasmodial potentials and the resultant effects of the methanolic leaf extract of Daniella oliveri (D.oliveri) on the biochemical and haematological parameters of the infected and treated albino mice. A total of 30 mice were randomized to six groups; 1 (positive control), 2 (negative control), 3 (normal control), 4, 5 and 6 (treatment groups) of five mice per group, body weights of mice were measured before and after infection and treatments, the mice were Infected intravenously with 0.2 ml of 1x107 standard inoculum of chloroquine sensitive Plasmodium berghei infected erythrocytes on the first day (day 0), treatment commence 72 hours later (day 3), continued for 5 days to terminate on day 7. On day 8, the Swiss Albino mice used for antiplasmodial activity were subjected to euthanasia under chloroform, aseptically dissected and blood was collected through cardiac puncture in lithium heparin bottle for biochemical assays and in an ethylene diamine tetra- acetic acid (EDTA) bottles for haematological assays.All mice in the treatment group showed decrease in body weight except for normal control group that showed increase in body weight. Methanolic leaf extract of D.oliveri contains some secondary metabolites that are hepato-protective in nature with no significant effects on the biochemical and hematological parameters of the malaria infected and treated albino mice.
