Background: Malaria is a parasitic infection that is common in the tropical and sub-tropical regions of the world. It is estimated to kill one million individuals annually. Detarium microcarpum (Fabaceae family) is used traditionally for the treatment of malaria, diabetes, hypertension, convulsions, pneumonia, leprosy, and meningitis. The purpose of this research was to evaluate the antiplasmodial potential and safety profile of the methanol extract of D. microcarpum stem bark. Methods: The extract was subjected to phytochemical screening and oral median lethal dose (LD50) estimation. Using curative, suppressive, and prophylactic experimental animal models, antiplasmodial activity was assessed in mice infected with chloroquine-sensitive Plasmodium berghei berghei. Biochemical and hematological tests were conducted in rats orally administered with the extract for 28 days. One-way analysis of variance (ANOVA) was used to analyze the data, followed by Dunnett's post hoc test. Results: Alkaloids, flavonoids, saponins, tannins, triterpenes, and glycosides were found in the extract through phytochemical analysis. When compared to the negative control group, the extract at the tested doses (200, 400, and 800 mg/kg) showed a significant (P < 0.001) curative, suppressive, and prophylactic effect and significantly (P < 0.001) prolonged the survival time of mice in the treated groups. The extract had an insignificant (P > 0.05) effect on the biochemical and hematological parameters tested. Conclusions: The results suggest that the stem bark extract of D. microcarpum at the doses tested possesses antiplasmodial activity and is relatively safe after short-term use.

Aim: In this study, the methanol stem bark extract of Detarium microcarpum was evaluated for sub-chronic, biochemical and histopathological studies. Methodology: Sub-chronic toxicity studies was investigated in rats administered with 35, 70 and 140 mg/kg doses of the extract orally for 28 days using standard laboratory procedures after the acute toxicity was carried out. Results: The median lethal dose (LD50) of the extract was calculated to be equal to (≥) 5000 mg/kg body weight in rats orally. Serological studies revealed significant (p<0.05) decrease in Alanine aminotransferase (ALT) at all doses tested, while at 140 mg/kg it caused a significant (p<0.05) increase in Alkaline Phosphatase (ALP). At doses of 70 and 140 mg/kg there was a significant (p<0.05) reduction in creatinine level. Histopathological studies on the liver showed moderate hepatocellular necrosis at doses of 35 and 70 mg/kg, while at 140 mg/kg there was intense hepatocellular necrosis,  Kupffer cells and lymphocytes hyperplasia. The Kidney showed intense necrosis of tubules and glomerular necrosis with lymphocytes hyperplasia at all doses tested.  The spleen also showed intense lymphocyte hyperplasia at all doses with sinusoidal congestion at the lowest dose of 35 mg/kg. The heart showed slight necrosis of cardiac muscle cells at all doses with blood congestion at 35 and 70mg/kg body weight. Conclusion: The study indicates that prolong use of the extract in the management of disease conditions may be associated with some adverse effect of some vital organs.

Aim: The aim is to evaluate the antioxidant potentials of Eucalyptus camaldulensis methanol stem bark extract (ECMSBE) on Wister albino rats. Methodology: The phytochemical screening of ECMSBE was conducted using standard methods. A total of 36 albino rats were used for the antioxidant studies. The rats were divided into six (6) groups of six rats. Control group received distilled water orally at 2ml/kg. Oxidative stress was induced in groups 2 to group 6 CCl4 (1ml/kg, s.c) at every 72hrs for 10 days. Group 2 was untreated while groups 3 – 6 received doses of 50, 100, 150 and 200mg/kg of ECMSBE respectively. On the 11th day, the rats were sacrificed and the liver was removed and homogenised and oxidative stress parameters were determined. Results: Phytochemical analysis of ECMSBE revealed the presence of saponins, flavonoids, tannins, phenols, glycosides, steroids, terpenoids and resins. There was no significant difference (P<.05) between the CCl4 induced group and the group treated with ECMSBE (50mg/kg). However, their concentrations were significantly different from the group treated with ECMSBE (100mg/kg – 200mg/kg) when compared to the group treated with CCl4 Only. The CCl4-induced group had its vitamin A, vitamin C and vitamin E concentrations significant different (P<.05) from the groups treated with ECMSBE (100, 150 and 200mg/kg body weight). There was no significant difference (P>.05) in the levels of SOD, CAT and GPx between the group induced with CCl4 only and the group treated with ECMSBE (50mg/kg), however, it these concentrations were significantly higher (P<.05). The enzymatic antioxidants concentration in the normal control group was not significantly different (P>.05) when compared the group that was treated with ECMSBE (200mg/kg) Conclusion: The result suggest that the extract of E. camaldulensis possessed antioxidant properties which can be used as effective protecting agents against oxidative stress and other diseases.

Aim: This study is aimed at evaluating the effects of the aqueous stem bark extract of Stereospermum kunthianum on CCl4-induced hepatotoxicity in rats. Methodology: Analysis of qualitative phytochemical components and antioxidant activity were carried out. Experimental rats were randomly divided into six groups of five rats each. Group 1: served as the normal control group. Group 2: was administered with CCl4 only at a dose of 3 ml/kg b.wt by single intraperitoneal administration. Group 3: served as the standard control group.   Group 4: was administered with 200 mg/kg b.wt of the aqueous stem bark extract + CCl4. Group 5: was administered with 400 mg/kg b.wt of the aqueous stem bark extract + CCl4. Group 6: was administered with 600 mg/kg b.wt of the aqueous stem bark extract+ CCl4. Results: The phytochemical analysis showed the presence of flavonoid, phenols, saponins, and terpenoid while tannins and alkaloids were absent. The antioxidant activity showed that the extract significantly (P<0.05) inhibits Ferric Reducing Antioxidant Power (FRAP) and Thiobarbituric Acid Reactive Substances (TBARS), giving high activity as the concentration of the extract increases. The elevated levels of ALT and AST coupled with Conjugated bilirubin, Total bilirubin, and total protein caused by CCl4 administration were all reduced significantly (P<0.05) by the extract in dose dependent manner. Conclusion: These findings demonstrated that stem bark extract of Stereospernmum kunthianum could be an alternative medication for liver injury.

Different parts of Vitellaria paradoxa plant have many applications in ethno-medicine. Some of the uses of this plant include treatment of diarrhoea and other GIT disorders. In this study the antidiarrhoeal activity of the ethanol extract of Vitellaria paradoxa was evaluated using three experimental models: Castor oil-induced diarrhoea; small intestinal motility and intestinal fluid accumulation (enteropooling) models in mice. Five groups of five mice were used for each model. Group one mice received 10 ml/kg of distilled water, while groups 2, 3, and 4 received 125, 250 and 500 mg/kg of the extract orally respectively. Group 5 mice received Loperamide 5 mg/kg orally. Oral median lethal dose (LD50) of the extract was determined using OECD (2008) Guideline 425. Phytochemical studies were conducted using standard procedures. The LD50 was estimated to be greater than 5000 mg/kg body weight and there were no signs of mortality or visible signs of toxicity in all the mice treated. Phytochemical screening revealed the presence of carbohydrates, alkaloids, flavonoids, saponins, tannins, triterpenes, steroids, cardiac glycosides and anthraquinones glycosides. Extract showed a dose-dependent anti-diarrhoeal activity by reducing stool frequency and consistency. The extract at the higher doses significantly (p < 0.05) inhibited GIT motility and castor oil-induced enteropooling, comparable to that of the reference control drug Loperamide. The study showed that ethanol stem bark extract of Vitellaria paradoxa possess anti-diarrhoeal activity and thus justifies its ethno-medicinal use in the treatment of diarrhoea.

We investigated the antioxidant and anti-inflammatory effects of a 70% v/v ethanol extract of the stem bark of Antrocaryon micraster on murine models of carrageenan-induced pleurisy and paw oedema. Rat pleural fluid was analysed for volume, protein content, and leucocytes, while lung histology was assessed for damage. Lung tissue homogenates were assayed for glutathione (GSH), superoxide dismutase (SOD), catalase (CAT), malondialdehyde (MDA), and myeloperoxidase (MPO). Phytochemical analysis was carried out on the stem bark. Acute toxicity studies were conducted in rats. In the pleurisy model the extract (30–300 mg/kg) significantly reduced the volume and amount of proteins and leucocytes in the exudate and also protected against lung injury. Tissue level of GSH and SOD and CAT expression were increased while MDA level and MPO activity were reduced. The peak and total oedema responses were significantly suppressed when given both preemptively and curatively in the mice paw oedema test. Saponins, alkaloids, triterpenoids, and tannins were present in the stem bark. A. micraster extract exhibited no apparent acute toxicity. We conclude that the ethanolic stem-bark extract of A. micraster has antioxidant action and exhibits significant anti-inflammatory activity through suppression of pleurisy and paw oedema induced with carrageenan.

ABSTRACTBackground: Streptococcus mutans is plaque-forming initiator bacteria. Plaque on the surface base of denture can cause color changing, bad breath, inflammation, and infection  called denture stomatitis. Denture hygiene must be maintained by denture soaking in 0.2% chlorhexidine gluconate. However, 0.2% chlorhexidine gluconatethat used incessantly can cause side effects such as the changing of denture color and the fading of denture base pigmentation. The ironwood stem bark extract can be an alternative for denture cleanser material. Objectives: To analyze the effect of ironwood stem bark extract on the growth of Streptococcus mutans on heat cured type acrylic resin denture plate. Methods: True experimental laboratories research was used with post test only control group design using 9 treatment groups which are 5%, 10%, 20%, 40%, 60%, 80%, 100% concentration of ironwood stem bark extract, 0.2% chlorhexidine gluconate and aquadest. The treatment was performed with 3 times repetition resulting in 27 total samples. Antibacterial activity was measured by calculating the bacteria colony number. Results: The 5% and 10% concentration of ironwood stem bark extract were effective in reducing Streptococcus mutans with30.3 CFU/ml and 10.3 CFU/ml average colony number. The ironwood stem bark extracts with 20%, 40%, 60%, 80%, 100% concentration are effective and equivalent to 0.2% chlorhexidine gluconate against Streptococcus mutans with 0 CFU/ml average value. Conclusion: The 20%, 40%, 60%, 80%, 100% concentration of ironwood stem bark extract is equally effective as 0.2% chlorhexidine gluconatein killing Streptococcus mutans,exhibiting potential to be an alternative for denture cleanser material.Keyword: 0.2% Chlorhexidine gluconate, ironwood stem bark extract, acrylic resin denture plate heat cured type, Streptococcus mutans.

Background. Terminalia mantaly is used in Cameroon traditional medicine to treat malaria and related symptoms. However, its antiplasmodial efficacy is still to be established. Objectives. The present study is aimed at evaluating the in vitro and in vivo antiplasmodial activity and the oral acute toxicity of the Terminalia mantaly extracts. Materials and Methods. Extracts were prepared from leaves and stem bark of T. mantaly, by maceration in distilled water, methanol, ethanol, dichloromethane (DCM), and hexane. All extracts were initially screened in vitro against the chloroquine-resistant strain W2 of P. falciparum to confirm its in vitro activity, and the most potent one was assessed in malaria mouse model at three concentrations (100, 200, and 400 mg/kg/bw). Biochemical, hematological, and histological parameters were also determined. Results. Overall, 7 extracts showed in vitro antiplasmodial activity with IC50 ranging from 0.809 μg/mL to 5.886 μg/mL. The aqueous extract from the stem bark of T. mantaly (Tmsbw) was the most potent (IC50=0.809 μg/mL) and was further assessed for acute toxicity and efficacy in Plasmodium berghei-infected mice. Tmsbw was safe in mice with a median lethal dose (LD50) higher than 2000 mg/kg of body weight. It also exerted a good antimalarial efficacy in vivo with ED50 of 69.50 mg/kg and had no significant effect on biochemical, hematological, and histological parameters. Conclusion. The results suggest that the stem bark extract of T. mantaly possesses antimalarial activity.
