Introduction: Pain is managed using conventional drugs like paracetamol, aspirin and diclofenac among others. Synthetic drugs have many side effects. This study aimed at evaluating the analgesic potential of the dichloromethane leaf extracts of Eucalyptus globulus and Senna didymobotrya in mice.Methods: The dichloromethane leaf extracts of E. globulus and S. didymobotrya were subjected to quantitative phytochemical analysis using gas chromatography-mass spectrophotometry (GC-MS). In vivo analgesic evaluation comprised of nine groups of animals (Swiss albino mice): normal, positive, negative control and six experimental groups that received 25, 50, 100, 150, 200 and 250 mg/kg body weight of each plant extract intraperitoneally. Thirty minutes later, they were injected with 0.01 mL of 2.5% formalin. The animals in positive control group were administered diclofenac (15 mg/kg) and formalin, the normal control mice received 3% dimethyl sulfoxide (DMSO) in normal saline, while the negative group received DMSO in normal saline and formalin. All the doses were administered intraperitoneally. The duration of shaking and licking of the injected paw was scored and analyzed.Results: The analysis revealed that E. globulus contained alpha-pinenes, endo-fenchol, α-eudesmol, myrcene, camphene, alpha-phellandrene, limonene, and camphor while S. dymobotrya possessed camphene, alpha-phellandrene, limonene, and camphor. In the late phase, E. globulus at the doses of 25, 50, 100, 150, 200 and 250 mg/kg reduced the paw licking time by 34.03%, 60.79%, 84.33 %, 90.65%, 94.49%, 98.52%, respectively while S. didymobotrya extract reduced the paw licking time by 26.48%, 32.96%, 87.04%, 91.27%, 93.40%, 90.97%, and 96.82%, respectively.Conclusion: The results of this study validate and support the traditional uses of these plants as analgesics.

Abstract Stachytarpeta jamaicensis L. Vhal (SJ) tea has been empirically used as an anthelmintic, but scientific evidence on its use as an anthelmintic against Fasciola sp. is still limited. The aim of this study was to determine the effective concentration of SJ tea as an anti-Fasciola. S. jamaicensis leaves were cut, dried and then packed in the form of tea bags. The presence of secondary metabolites in the tea was also analyzed phytochemically. The anthelmintic activity assay of SJ tea was carried out using an in vitro experimental design with a post-test with control group design. The in vitro test consisted of negative control (0.9% NaCl), positive control (10% Albendazole) and SJ tea with a concentration of 10%, 5%, and 2.5%. The worm’s movement was observed and the time required for the death of Fasciola was recorded and analyzed. Phytochemical analysis shows that SJ tea contained alkaloid compounds, flavonoids, saponins, tannins and triterpenoids. Time required for death of Fasciola in the positive control, the negative control, the tea concentration of 10%, 5%, and 2.5% were 18.75, 168.75, 23.75, 42.5, and 66.25 min, respectively. S. jamaicensis tea with a concentration of 10% showed comparable effectiveness (p>0.05) to standard reference 10% Albendazole as an anti-Fasciola and resulted in the fastest death of Fasciola fluke compared to other concentrations of the tea. The results of this study indicate that SJ tea can be used as an alternative in overcoming Fasciola infestation. Further works are required to determine its safety when used in vivo.

<p class="Abstract">In this study the antidiarrheal activity of ethanolic extracts of the leaves of <em>Mikania cordata</em> and <em>Litsea monopetala</em> was evaluated. Diarrhea was induced in mice by oral administration of castor oil (0.5 mL) 30 min after the administration of the extracts. During a 4 hour study the number of diarrheal feces and percentage inhibition of the extracts (200 and 400 mg/kg body weight) was determined. Loperamide (3 mg/kg body weight) served as standard and belonged to the positive control group. The extracts exhibited potent antidiarrheal activity as well as achieved statistically significant p value (p&lt;0.01 and p&lt;0.05) compared to control group. Among the extracts the highest percentage inhibition of defecation (60%) was recorded for leaf extract (400 mg/kg body weight) of <em>L. monopetala</em>. So, the study corroborates the significant antidiarrheal activity of <em>M. cordata</em> and <em>L. monopetala</em> leaf extracts and raises the demand of further sophisticated investigation.</p><p> </p>

Objective: The current study was carried out to evaluate the anthelmintic activity of the rhizome extract of Curcuma longa as an alternative source of effective remedies for nematodiasis.Methods: The anthelmintic activity of the C. longa was assessed in vitro against Haemonchus spp., a gastrointestinal (abomasum) parasite of goats. Different concentrations of the extracts (1 mg/mL, 2.5 mg/mL, 5 mg/mL, and 10 mg/mL) in phosphate-buffered saline (PBS) were tested, and the results expressed in terms of time of paralysis (minute) and time of death (minute) of the worms. Albendazole (1 mg/mL) was used as a reference (positive control) and PBS as a control group (negative control).Results: The qualitative phytochemical analysis of the methanolic extract (ME) of the plant disclosed the presence of alkaloids, glycosides, terpenoids, flavonoids, tannins, saponins, phenol, anthraquinone, and carbohydrates; whereas, the aqueous extract (AE) showed the presence of alkaloids, carbohydrate, flavonoids, and saponins. Both ME and AE of the C. longa (rhizome) expressed significant efficacy (p≤0.05) in causing paralysis as well as the death of the worms within 12 h of exposure at all tested concentrations, as compared to the negative control. The rhizome extracts of C. longa showed dose-dependent efficacy in causing paralysis of the worm motility and the final progression to death. The results showed that the ME at 10 mg/mL was significantly more potent (p≤0.05) over the AE.Conclusions: This study concluded that the rhizome extract of C. longa exhibited potent anthelmintic efficacy against the nematode parasite, Haemonchus spp.

ABSTRACTEthnopharmacological relevance of the studyDiarrhea remains one of the main killers of children aged below five years. Traditional antidiarrheal remedies form a potentially viable source of novel low cost efficacious antidiarrheal remedies in low resource settings. There is therefore a pressing to scientifically evaluate these remedies.Aim of the studyThis study aimed to investigate the in vivo and in vitro antidiarrheal activity of Bidens biternata a herb species used in traditional Ayurvedic medicine in the management of diarrhea.Materials and MethodsIn the castor oil test twenty (20) adult Sprague-Dawley rats were randomized to the negative control (normal saline), positive control (5 mg/kg loperamide), (200 mg/kg Bidens biternata extract) and (400 mg/kg Bidens biternata extract) groups (n=5 in each group). Castor oil (4 ml/kg) was then administered to the animals one hour after administration of the respective treatments after which the total mass of fecal output excreted after four (4) hours was determined.In the charcoal meal test fifteen (15) Sprague Dawley rats were randomized to the negative control (normal saline 5 ml/kg orally), the positive control (atropine sulphate 0.1 mg/kg i.p) and test (400 mg/kg Bidens biternata extract) groups (n=5). Charcoal meal was then administered via oral gavage to each rat thirty (30) minutes after the administration of the various treatments. The distance covered by the charcoal meal from the pylorus was then determined after sacrifice of the animals.In the enteropooling test twenty (20) Sprague-Dawley rats were randomized to the negative control (5% v/v ethanol in normal saline), positive control (5 mg/kg loperamide) and test (400 mg/kg Bidens biternata extract) groups and prostaglandin E2 (PGE2) (100μg/kg) administered immediately after the treatments. The animals were then sacrificed half an hour later and the volume of the small intestine contents determined. The effects of different concentrations of Bidens biternata extract (0.5. 1.0, 2.0, 3.0 and 5.0 mg/ml) on jejunal contraction were investigated and a dose-response curve constructed using the experimental data after which The ED50 dose determined. The effect of tamsulosin (α1 adrenergic blocker), yohimbine (α2 adrenergic blocker), propranolol (β adrenergic blocker) and naloxone (μ opioid blocker) on the contractile activity of the extract were also investigated.The experimental data were expressed as mean ± standard error of mean (SEM) and then analyzed using one way ANOVA followed by Tukey’s post hoc test in cases of significance (set at p<0.05).ResultsThe freeze dried extracts of Bidens biternata had significant antidiarrhealeffects in the castor oil induced diarrhea model (p=0.0075) with maximal activity being observed at the 400mg/kg dosage level (1.66± 0.81g vs. 4.54 ± 0.51 g negative control, p=0.01). Bidens biternata extract had significant effects on intestinal motility in the charcoal meal test compared to the control group (43.61 ± 4.42% vs. 60.54 ± 3.33%: p= 0.02). Bidens biternata extract had a significant effect on PGE2 induced enteropooling (3.06 ± 0.07 ml vs. 4.74 ± 0.10 ml; p<0.001).The freeze dried extracts of Bidens biternata had a significant negative effect on the contractility of the isolated rabbit jejunum (p<0.001). The effects of the extract were significantly attenuated by tamsulosin (53.94 ± 4.20% vs. 80.57 ± 4.09%; p=0.0067) and naloxone (53.94 ± 4.20% vs. 73.89 ± 7.26 %; p=0.0358). Yohimbine (p=0.4598) and propranolol (p=0.5966) however did not have any significant effect on the contractile activity of the extract.ConclusionsThe freeze dried extract of Bidens biternata possess significant antidiarrhealactivity in both in vitro and in vivo models which appears to be mediated by modulating both the intestinal motility as well as the secretory activity. The results of this study also validate its traditional use as an antidiarrheal remedy.

Background: The present study was performed to explore whether the aqueous extract of Senecio biafrae (S. biafrae) roots provide any in vivo protective activity against carbon tetrachloride (CCl4)-induced hepatotoxicity in male albino rats. Methods: Rats (150-200 grams) were grouped into five groups (A-E) of six rats each and were treated orally for twelve days with 72 hourly administration of CCl4 (1 mL/kg) as follows: Group A received distilled water only (negative control), Group B was administered distilled water plus CCl4 (positive control), Group C was administered 400 mg/kg extract and CCl4, Group D received 200 mg/extract and CCl4, while Group E was administered standard drug (Silymarin 25mg/kg, PO). Results: Pre-treatment with the extract of S. biafrae (200 or 400mg/kg) or Silymarin (25mg/kg) caused significant restoration in the biomarkers as evaluated by reducing the levels of malondialdehyde, transaminases and elevating the levels of superoxide dismutase, catalase and glutathione peroxidase activities, which were altered by CCl4 toxicity. The extract at a dose of 400mg/kg demonstrated similar activities comparable to the standard drug (Silymarin). Conclusion: The results of this study indicate that the root extract of S. biafrae possesses hepatoprotective and anti-oxidant properties which may be due to the presence of phytochemicals in it.

Background: Although scientific studies have confirmed the action of homeopathic high dilutions in living organisms an endless debate on the choice of the most fitting dilution, the frequency of administration and the dose (amount of medicine) still remains. Aims: This study sought to assess the in vivo effect of 2 different concentrations of Arsenicum album 30cH in order to elucidate some problems in the homeopathic notion of dose. Methods: Male Wistar rats previously intoxicated with sodium arsenate by peritoneal injection were treated with undiluted Ars 30cH and Ars 30cH in 1% solution administered by oral route. Atomic absorption spectroscopy was employed to measure the levels of arsenic retained in the animals as well as the amounts eliminated through urine. Urine samples were collected before and after and during treatment. A positive control group (intoxicated animals) and negative control group (non-intoxicated animals) were administered only the vehicle used to prepare the medicine (ethanol). Results: The groups treated with undiluted Ars 30cH and Ars 30cH in 1% solution eliminated significant amounts of arsenic through urine when compared to the control groups. The group treated with undiluted Ars 30cH eliminated significantly higher amounts of arsenic than the group treated with the same medicine in 1% solution. Conclusion: These results suggest that undiluted Ars 30cH was more effective than in 1% solution in this experimental model.

Background and Aim: Global trend to remove the antibiotic growth promoter (AGP) from animals contributes to the exploration of successful measures to sustain production and reduces the intestinal diseases in the post-AGP era. Plant extracts, therefore, have been used to improve performance and intestinal health. Here, we conducted a study to evaluate the effects of neem (Azadirachta indica) leaf extracts (NLE) as alternatives to AGPs in broiler chickens. Materials and Methods: Sixty day-old broiler chicks were assigned to 12-floor pens, each stocked with five birds and divided into three treatment groups of four pens per treatment. The groups were: Negative control, basal diet without additives; positive control, basal diet with antibiotics and vitamins; and NLE treated group, basal diet supplemented with 0.1% aqua extract of neem leaves. Results: Overall feed intake was significantly (p≤0.05) highest in the positive control. Higher body weight, higher dressing percentage, and lower feed conversion ratio were observed in birds treated with NLE compared to the negative control group (p≤0.05) but not the positive control group (p>0.05). There was no significant variation in hematology between different groups. Furthermore, the economic evaluation indicated that the NLE treatment was found cheaper than control and antibiotic treatment in cost-benefit analysis. Conclusion: We suggest NLE might be a cheaper alternative to antibiotics in broiler production as indicated by improved body weight and feed efficiency.

Background: Gonorrhea cases experiencing antibiotic resistance are increasing due to inadequate treatment or failure to contribute to an increase in antibiotic resistance cases; WHO suggests adding herbal therapy treatment methods is expected to minimize the occurrence of drug resistance as much as possible. Previous studies that have been carried out using other herbal plants have not shown any potential to inhibit the growth of Neisseria gonorrhoeae bacteria, seen from the amount of extract concentration and the dosage and content of the compounds in the contents monitoring the time.Objective: To analyze the difference in the effect of various concentrations of Matoa Leafs Extract (Pometia Pinnata) compared to 500mg Levofloxacin on the increase in the growth inhibition of Neisseria gonorrhoeae.Methods: This is true-experimental research with a post-test-only control group with a randomized design. The sample in this study was the microorganism Neisseria gonorrhoeae obtained through vaginal swabs in 2 females (FSW) positive for Gonorrhea by gram staining and microscopic examination and culture on Chocolate Agar Plant (CAP) media. The culture was then suspended in CAP media. Matoa Leaf extract concentration of 100%, 80%, 60%, 40%, 20%, positive control with Levofloxacin 500 mg and negative control with distilled water with four replications and monitoring in 24 hours, 48 hours, 72 hours, and 96 hours. Data analysis used Kruskal-Wallis, Mann-Whitney, and cohen's test. Result: Levofloxacin 500mg in inhibiting Neisseria Gonorrhoeae bacteria is very effective, and Matoa Leaf extracts 60% and 40% P=0,026 have a strong enough potential to inhibit the growth of Neisseria gonorrhoeae bacteria with the same potential strength. The cohen's test 1.4 effect the levofloxacin 500mg provides a significant influence inhibiting Neisseria Gonorrhoeae.Conclusion: Matoa Leaf extract 60%, and 40% have solid antibacterial potential, although not as strong as Levofloxacin 500mg.
