Sickle cell disorder is a genetic ailment with enormous social and economic burden for patients and caregivers. The most promising management apart from being expensive particularly for poor African people, faces some major incompatibility problems. The patients consequently rely on herbal therapy which could be prepared in single or combination forms to manage the painful episodes and its complications. This present study aimed to formulate polyherbal combination and evaluate three purposively selected plants previously reported for their antisickling activities. The polyherbal products were formulated using both aqueous and 70% ethanol extracts into different combinational ratio with the best in 1:1:1 and evaluated for its antisickling activity. The antisickling activity involved both the inhibitory and reversal effects at varying concentrations from 1.0 mg/ml to 6.0 mg/ml using ciklavit as the positive control. The best inhibitory activity was found in ethanol extract of Piper guineense, Gongronema latifolium and Cymbopogon citratus (PGC) with 70.09 ± 0.67% when compared with the positive control (59.25 ± 0.05%) at 4.0 mg/mg while the reversal ability was 67.87 ± 1.23%. The aqueous extracts of the combinations had activity above 50% with the exception of PGC (2:3:1) which is a little less than 50% (46.67 ± 0.98%) while the highest was 60.02 ± 0.87%. The polyherbal ethanol extract had better effects than the aqueous extract and the standard drug used in this study.

Antiplasmodial and analgesic effects of crude ethanol extract ofPiper guineensewas investigated in mice. The antiplasmodial and analgesic efficacy of the extract was judged on its ability to reduce parasitemia and writhing, respectively, in mice. The antiplasmodial screening involved treating infected mice with 200, 400, and 600 mg/kg body weight of extract while the positive control group was given standard artesunate drug. The analgesic test was carried out by administering 1000, 1500, and 2000 mg/kg body weight of extract to three groups of healthy mice, respectively, after induction of pain with 0.75% acetic acid. The positive control group was given aspirin drug. Parasitemia was reduced by 28.36%, 43.28%, and 62.69% in a dose-dependent pattern in the curative test which was significantly different (P<0.05) from 96.03% of the standard drug. The reduction of writhing by mice given the extract was also dose-dependent (36.29, 45.43, and 59.07%). Aspirin drug was however more effective (86.36%). The extract was safe at 2000 mg/kg body weight. Phytochemical screening revealed the presence of flavonoids, tannins, phlobatannins, terpenoids, and coumarins. Result obtained in this study demonstrated the efficacy of ethanol extract ofPiper guineenseas an antiplasmodial and analgesic agent.

Aim: This study was conducted to determine the anthelmintic activity of aqueous and ethanol extracts of Paraserianthes falcataria bark against Haemonchus contortus. Materials and Methods: Ethanol extract of bark (E.E.B.) waste and aqueous extract of bark (A.E.B.) waste of P. falcataria (at concentrations 0, 0.2, 0.4, 0.8, 1, 2.5, and 5%) and albendazole (2 mg/ml) as the positive control were placed in separate Petri dishes (50 mm). Twenty H. contortus worms were placed in Petri dishes and incubated at 37°C for 0.5, 1, 2, 3, 4, 5, 6, and 12 h. Mortality of each worm was ensured by pressing the body of the worm with a pair of tweezers and keeping it in lukewarm water for 5 min before declaring it dead. Mortality is defined as amount of death individuals and time of mortality of each worm was recorded. The parasites were then observed using scanning electron microscopy (SEM) at an accelerating voltage of 15 Kv. Statistical analysis was performed using SPSS 21.0 software, two-way ANOVA followed by Tukey's test to detect significant differences (p<0.05). The result was expressed as the mean ± standard deviation. Results: The E.E.B. and A.E.B. of P. falcataria contained active compounds, such as tannin, alkaloid, flavonoid, saponin, steroid, and triterpenoid. E.E.B. had a higher content of phenol, while A.E.B. had a higher content of flavonoid. In this study, P. falcataria showed a significant effect (p=0.00) on H. contortus in vitro. E.E.B. (0.8%) was able to exterminate H. contortus completely after 6 h, more effective than A.E.B. (5%) while the positive control requires (2 mg/ml) after 2 h. SEM analysis of the worm treated with E.E.B. and A.E.B. showed damaged cuticle structure. Conclusion: The aqueous and ethanol extracts of P. falcataria bark waste demonstrated anthelmintic activity against H. contortus.

Background: A snake bite is fundamentally an injury often resulting in puncture wounds meted out by the animal's fangs and occasionally resulting in envenomation. Rate of snake bites around 5,400,000 bites per year leads to over 2,500,000 envenomings and around 125,000 fatal cases annually. Snake venom enzymes are rich in metalloproteinases, phospholipaseA2, proteinases, acetylcholinesterases and hyaluronidases. Objective: Cyphostemma adenocoule is traditionally being used for the treatment of snake bites in Eritrea. The present research was aimed at evaluating the snake venom enzyme inhibition activity of C. adenocoule against puff adder venom and developing a base for the traditional use of the plant against snakebites in Eritrea. Methods: The anti-venom activity of C. adenocoule was assessed in-vitro through phospholipaseA2 enzyme inhibition assay using egg yolk as a cell. The ethanol and chloroform extracts of C. adenocoule showed in vitro anti phospholipase A2 activity, whereas the water extracts of the plant showed no activity. Results: Among the extracts of C. adenocoule, the highest percentage of inhibition was obtained from chloroform extract (95.55% at 100mg/ml). The extract showed prominent activity at different concentrations (34.7% at10mg/ml, 48.8% at 20mg/ml, 54.8% at 40mg/ml, 60.9% at 60mg/ml, 80.5% at 80mg /ml). The ethanol extract also showed certain activity at various concentrations (25.22% at10mg/ml, 14.78% at 20mg/ml, 2.6% at40mg/ml). The activity of the chloroform extracts increases as concentration increases, whereas the activity of the ethanol extracts decreases as concentration increases. The aqueous extract of C. adenocoule did not show any activity at all concentrations. Conclusion: In this study, the chloroform and ethanol extracts of the plant inhibited the enzyme of interest and thus proved the efficacy of anti-snake venom activity of the plant.
