“…Despite several reports of accidental poisoning in humans by unprocessed seeds of R. communis (De Paepe et al 2005, Nishiyama et al 2005, Lucas et al 2006, Al-Tamimi et al 2008) cases of poisoning in animals have occurred after the intake of processed seeds (Worbs et al 2011). In Brazil, the data reported to date were mainly from experimental studies in cattle, sheep and rabbits (Armién et al 1996, Brito & Tokarnia 1997, Tokarnia & Döbereiner 1997 and spontaneous cases of poisoning in cattle have not been described.…”

Pesq. Vet. Bras. 34(9) The aim of this study is to report cases of spontaneous poisoning of cattle by Ricinus communis (castor beans) in Paraíba, a semiarid region of northeastern Brazil. The cases were observed in 2 herds on neighboring properties in 2013. Clinical signs developed within 6-24 h and consisted of weakness, tachycardia, dyspnea, profuse watery diarrhea, dehydration, depression, instability, cramps, permanent lateral recumbency and death within 48-72 h. Of the 60 cattle at risk, 19 were affected and 14 died. Five fully recovered after the course of 12 days. Three animals were necropsied. The main gross lesions were hemopericardium, hemothorax, pulmonary edema, petechial hemorrhages in the epicardium and endocardium, ecchymoses at the papillary muscles and suffusions on the intercostal muscles. Hemorrhages were also observed in the abdominal cavity, spleen and mucosa of the abomasum and small intestine. The rumen content was liquid with a large amount of castor bean seeds. There were circular, whitish and focally diffuse areas in the liver parenchyma. The main microscopic lesions consisted of multifocal coagulative myocardial necrosis with the presence of mononuclear cell infiltration and varying degrees of bleeding between cardiac muscle fibers. The abomasum and small intestine mucosae and submucosa had mild edema and mononuclear and polymorphonuclear inflammatory cell infiltration. The diagnosis of R. communis was based on the history of plant consumption, clinical signs, pathology of the disease and the presence of large amounts of castor bean seeds in the forestomachs.

“…The ingestion of seeds has occurred for the purpose of committing suicide [3][4][5][6][7], under the direction of practitioners of folk medicine [2,8] or when children have eaten the seeds [11,12,30]. Fatalities have occurred for two adult women: one ingested three or four seeds, 30 h prior to going to the emergency room [8], and one consumed seven crushed seeds, approximately 12 h before being treated at the hospital [6].…”

“…The higher toxicity of younger seeds is often referred to and is related to the greater malleability of the seed; however, there is an absence of data concerning the time frame over which the shell hardens and if there is a change in the activity of abrin as the seed ages. An understanding of these processes may help explain differences in cases where a few seeds result in death [6,8], compared to incidents where consumption of a high number of pierced/crushed seeds ends with full patient recovery [3][4][5]7,8,11,12,30]. Despite the many variables that affect patient outcomes upon ingestion of the toxin, obtaining more information about abrin content in seeds is an attainable goal.…”

A preliminary study was conducted to determine any modifications to basic soil properties following over-abundance of Bambusa bambos, a native bamboo species, that rapidly expanding its population in Intermediate and Dry Zone forests in Sri Lanka. Soil samples taken from representative sites of bamboo-dominated (BAM) and non-bamboo (NBM) forest patches were analyzed for pH, total nitrogen (N), phosphorus (P), soil moisture and microbial biomass carbon (MBC). A growth assay was carried out with Ricinus communis seedlings in BAM and NBM soils (sterilized/unsterilized) in a glasshouse. The soil analysis revealed significantly higher N, P and moisture in BAM soils than in NBM. BAM soils were clayey in nature compared to silty soils in NBM. Ricinus communis grown in BAM soils performed better throughout the experimental period, perhaps due to higher soil nutrients. Ricinus communis grow better in unsterilized soils irrespective of bamboo, indicating a facilitative role of soil microbes on the growth of plants. The preliminary results suggest that either B. bambos spread has the potential to increase the soil fertility status or else B. bambos expands its population preferably on nutrient-rich clayey soils. Therefore, further studies are needed in order to confirm the impacts of B. bambos on edaphic properties which may eventually influence the growth of co-occurring native species.
