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: 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: 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.

Secondary metabolite compounds from Morus nigra (MN), has been shown to have antioxidant and antimicrobial activities. moreover, phenolics and flavonoids contained in this species are partly responsible for those activities. This study aims to evaluate the mode of action of MN stem bark extract and its antibacterial activity against Streptococcus mutans. The stem bark of MN was macerated using ethanol as a solvent for 72 h. Furthermore, the antibacterial activities of the extract were evaluated using Agar diffusion and microdilution methods, by determining the zone of inhibition and the minimum inhibitory concentration (MIC). Scanning electron microscopy (SEM) was used to observe the morphological changes induced by the extract. The protein and ion leakage from the bacterial cells were analyzed spectrophotometrically. The extract exhibited antibacterial activity against Streptococcus mutans, at a MIC value of 8mg/mL. Furthermore, it discovered via SEM that at 4xMIC, this extract could damage the membrane cell of Streptococcus mutans. Finally, protein and ion leakage were observed in bacterial cells of Streptococcus mutans induced with this extract. MN stem bark extract is a potential herbal medicine, which has antibacterial activity against Streptococcus mutans.

Objective: This study was designed to investigate the sub-acute toxicity profile of hydro-methanol extract of Burkea africana  (BA) stem bark in rats. Methods: The stem bark of BA was extracted by cold maceration using 80% methanol. Twenty female albino rats were randomly assigned into four groups of five rats each. Group 1 (only distilled water). Groups 2-4 received the extract (100, 200, and 400 mg/kg) orally, once daily for 28 days. The rats were observed for signs of toxicity and the bodyweight (b.wt) of rats taken weekly. Blood samples were collected on day 28 for hematology and serum chemistry. Visceral organs were harvested for organ-somatic index and histopathology. Results: There were no toxicity signs observed and no significant (p< 0.05) change in body weight but the pulmo-somatic index was significantly (p< 0.05) higher at 400 mg/kg compared with the control and other treated groups. Significant (p< 0.05) increase in PCV, RBC, and MCV and significant (p< 0.05) decrease in MCHC, Total WBC count, neutrophils and lymphocytes were observed. Also, there were significant (p< 0.05) decreases in ALT, total protein, globulin, total bilirubin of test groups when compared with the control group. Urea concentration of test groups significantly (p< 0.05) increased when compared with that of the control group. Conclusions: BA stem bark extract can be said to have no deleterious effect on erythrocyte, but rather serve to improve erythropoiesis and also has no overt toxic effect on the visceral organs. Also the extract may have immunosuppressive and oxidative tendencies on prolong use.                                   Peer Review History: Received 12 January 2021; Revised 3 February; Accepted 25 February, Available online 15 March 2021 UJPR follows the most transparent and toughest ‘Advanced OPEN peer review’ system.

Miliusa velutina (MV) stem bark has various medicinal uses, but its hepatoprotective effect has not yet been studied. This study investigated the antioxidant and hepatoprotective activity of the ethanol extract of MV stem bark against carbon tetrachloride (CCl4)-induced liver injury. The ethanol extract of MV stem bark was evaluated for in vitro antioxidant activity which exhibited good antioxidant activity in terms of ferric reducing-antioxidant power assay (EC50, FRAP=4.04±0.00 µg/mL), total antioxidant capacity assay (EC50, TAC=8.73±1.08 µg/mL) and 1,1-diphenyl-2-picrylhydrazyl (EC50, DPPH=9.33±0.07 µg/mL) radical scavenging assay. Mice were pretreated with CCl4 (2.5 mL/kg body wight per day) in 4 consecutive weeks. After one hour taking CCl4 by oral administration, mice were treated with the ethanol stem bark extract of MV at various concentrations of 100, 200, and 400 mg/kg body weight. The MV stem bark at the dose of 400 mg/kg body weight effectively reduced the level of alanine transaminase (38±6.78 U/L) and aspartate transaminase (AST) in serum. Besides, the MV stem bark at the dose 400 mg/kg body weight reduced the malondialdehyde (3.12±1,19 nM MDA/g tissue) level, and increased the activity of reduced glutathione (896.21±22.69 nM GSH/g tissue) in liver. The observation of the microscopic cross section of liver tissue also revealed that the mice treated with stem bark extract of MV at the dose of 200 and 400 mg/kg body weight had significantly improvement in liver tissues compared to the non-treated control group. Histological analyses of the MV-treated group exhibited reducing inflammatory process and preventing liver necrosis and fibrosis. In summary, the hepatoprotective effect of MV stem bark was seemingly associated with its antioxidant activity.

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.

In most of the Ayurvedic remedies, Diospyros malabarica is used to obtain Rakthasthambana (coagulation) effect. The effect of leaves and stem bark extract of Diospyros malabarica on human blood coagulation was investigated using Lee and White method at Gampaha Wickramarachchi Ayurveda Institute in Sri Lanka. A total of 20 healthy individuals representing both sex were included in the study. For the test group, three tubes containing a volume of 0.5mL of stem bark extract were allocated, and the sap was replaced with normal saline for the tubes of the control group. A volume of 1mL of drawn blood was quickly added for every six tubes in situ, and all were incubated in a water bath at 37˚C. Every tube of two groups was observed carefully for a clot to measure the average clotting time of each group separately. Above procedure was repeated to all the fresh juice samples of stem bark and the leaves of Diospyros malabarica. The statistically significant reduction of average clotting time has proved that the stem bark of Diospyros malabarica and leaves of Diospyros malabarica have a highly significant effect on clotting cascade.
