Syzygium guineense is an important medicinal plant effective against hypertension, diabetes mellitus, and cancer but with no evidence of its teratogenicity. This study was planned to investigate the teratogenic potential of S. guineense leaves on rat embryos and fetuses. Five groups of Wistar albino rats, each consisting of ten pregnant rats, were used as experimental animals. Groups I-III rats were treated with 250, 500, and 1000 mg/kg of hydroethanolic extract of S. guineense leaves, and groups IV and V were control and ad libitum control, respectively. Rats were treated during day 6–12 of gestation. Embryos and fetuses were retrieved at day 12 and day 20 of gestation, respectively. The embryos were assessed for developmental delays and growth retardation. The fetuses were examined for gross external, skeletal, and visceral anomalies. In 12-day old rat embryos, crown-rump length, number of somites, and morphological scores were significantly reduced by the treatment of 1000 mg/kg of the extract. The external morphological and visceral examinations of rat fetuses did not reveal any detectable structural malformations in the cranial, nasal, oral cavities, and visceral organs. The ossification centers of fetal skull, vertebrae, hyoid, forelimb, and hindlimb bones were not significantly varied across all groups. However, even if not statistically significant, high-dose treated rat fetuses had a reduced number of ossification centers in the sternum, caudal vertebrae, metatarsal, metacarpal, and phalanges. Treatment with the hydroethanolic extract of S. guineense leaves produced no significant skeletal and soft tissue malformations. The plant extract did not produce significant teratogenic effects on rat embryos/fetuses up to 500 mg/kg doses but retarded the growth of embryos at high dose (1000 mg/kg) as evidenced by decreased crown-rump length, number of somites, and morphological scores. Therefore, it is not advisable to take large doses of the plant during pregnancy.

Soil sample collection Soil samples was collected from four different site Mercato, Koch, Jimma hospital and Yetebaberut of the sample collect different distances from the road side to a depth of 0.0-5.0cm using a soil auger. The soil samples were keeping in a polythene bags and labeled to avoid a mix up of the different soil samples. Then it was bright to the laboratory and keeps in the air dried place prior to analysis for lead and cadmium. Soil sample preparation Unwanted materials such as stones, leaves and debris was remove from the soil samples by hand picking and dried on an air dried oven.

Background In Ethiopia, the majority of animal owners throughout the country depend on traditional healthcare practices to manage their animals' health problems. This ethnoveterinary study was carried out in Ensaro District, North Showa Zone, and Amhara Region, Ethiopia, to identify medicinal plant species used by the local community to treat various livestock ailments. Methods To collect ethnobotanical information, a total of 389 informants (283 men and 106 women) were selected. Among these 95 traditional medicine practitioners were purposely chosen, while the remaining 294 were selected through a systematic random sampling method. Ethnobotanical data were collected through semi-structured interviews, participant observation, guided filed walks and focus group discussions. The Informant Consensus Factor (ICF) and Fidelity Level (FL) values, preference, and direct matrix exercise ranking were determined using quantitative methods. Statistical tests were used to compare indigenous knowledge of medicinal plants among different informant groups. Results A total of 44 ethnoveterinary medicinal plant species were collected and identified that were distributed across 43 genera and 28 families. The family Solanaceae stood first by contributing 4 species followed by Amaranthaceae, Asteraceae, Euphorbiaceae, Fabaceae and lamiaceae with 3 species each. Thirty- seven (88.09%) medicinal plants were collected from wild habitats, 6 medicinal plant species were collected from home garden. The most frequently used life form was shrubs (23 species, 54.76%) followed by herbs (13 species, 30.95%). The widely used parts of medicinal plants were leaves followed by roots. Prepared remedies were administered through drenching, dropping, smearing, eating, wrapping, fumigating and washing. There was significant difference in the indigenous knowledge of medicinal plants between gender, urban and rural people, general and key informants and among age groups. Conclusion Ensaro District is a relatively rich in diversity of ethnoveterinary medicinal plants together with a rich indigenous knowledge in the local communities to collect and effectively utilize for the management different livestock diseases. On the other hand, these days, agricultural expansion, fuel wood collection, cutting plants for fence, furniture and charcoal production are the major threatening factors of these plant resources. Thus, people of the study area must implement in situ and ex-situ conservation strategies to ensure sustainable utilization of these species.

Background: Malaria is among the ten top leading causes of morbidity and mortality in children under-5 years. Due to the rise of drug-resistant parasites and limited therapeutic efficacy of the available drugs, there is a need to search novel antimalarial drugs from medicinal plants commonly utilized as traditional medicines. Traditional medicines are often more available, affordable, sometimes are perceived as more effective than conventional antimalarial drugs, cultural acceptable and the relatively lower cost. Hence traditional medicine becomes the novel candidate for the search and development of drugs for the prevention and treatment of malaria.Objective: The present study aimed to review phytochemical constitute, safety and efficacy commonly used medicinal plants for malaria treatment in Ethiopia. Methods:A web-based literature search was done by using scientific databases including Pub Med, Science Direct, Web of Science and Google Scholar, with inclusion criteria of full length experimental, ethno-botanical and ethno medicinal survey articles reporting on anti-malarial medicinal plants conducted in Ethiopia. Results: The most commonly utilized medicinal plants for the treatment of malaria were Conclusion and recommendation: Aqueous leaf extract of Strychnos mitis possessed a potent chemo suppression of 95.5 % at a dose of 600mg/kg/day. Further chemical isolation, dosage form development, clinical trial, and toxicological study is recommended. Citation: Abera T, Ashebir R, Basha H, et al.
