Toxicol Res (Camb) 2023; 12:26-32. [PMID: 36866220 PMCID: PMC9972815 DOI: 10.1093/toxres/tfac078] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/15/2022] [Revised: 09/22/2022] [Accepted: 10/13/2022] [Indexed: 12/23/2022] Open
Abstract
A high-fat diet (HFD) is one of the most prominent causative factors for obesity and metabolic inflammation. The effects of HFD overconsumption on intestinal histology, expression of haem oxygenase-1 (HO-1), and transferrin receptor-2 (TFR2) remain elusive. The present study was conducted to analyze the effect of HFD on these parameters. To develop the HFD-induced obese model, rat colonies were divided into 3 groups; the control group was reared on normal rat chow, whereas groups I and II were given HFD for 16 weeks. Hematoxylin and eosin (H & E) staining revealed marked epithelial changes, inflammatory cell infiltrates, and destruction of mucosal architecture in both experimental groups as compared to the control group. Sudan Black B staining showed a high triglyceride deposition in the intestinal mucosa of animals fed on HFD. Atomic absorption spectroscopy revealed a decrease in tissue copper (Cu) and selenium (Se) concentration in both HFD experimental groups. Whereas the cobalt (Co) and manganese (Mn) levels were comparable to controls. The mRNA expression levels of HO-1 and TFR2 were found to be significantly upregulated in HFD groups compared to the control group. Hence, HFD consumption leads to histopathological changes and altered gene expression in the rodent intestine. So, one should remove HFD from daily meals to avoid related metabolic complications.

Abstract
Oleandrin is a highly lipid-soluble cardiac glycoside isolated from the plant Nerium oleander (Apocynaceae) and is used as a traditional herbal medicine due to its excellent pharmacological properties. It is widely applied for various disease treatments, such as congestive heart failure. Recently, oleandrin has attracted widespread attention due to its extensive anti-cancer and novel anti-viral effects. However, oleandrin has a narrow therapeutic window and exhibits various toxicities, especially typical cardiotoxicity, which is often fatal. This severe toxicity and low polarity have significantly hindered its application in the clinic. This review describes natural sources, structural properties, and detection methods of oleandrin. Based on reported poisoning cases and sporadic animal experiments, the pharmacokinetic characteristics of oleandrin are summarized, so as to infer some possible phenomena, such as enterohepatic circulation. Moreover, the relevant factors affecting the pharmacokinetics of oleandrin are analyzed, and some research approaches that may ameliorate the pharmacokinetic behavior of oleandrin are proposed. With the toxicology of oleandrin being thoroughly reviewed, the development of safe clinical applications of oleandrin may be possible given potential research strategies to decrease toxicity.

Abstract
Oleander is a spontaneous shrub widely occurring in Mediterranean regions. Poisoning is sporadically reported in livestock, mainly due to the ingestion of leaves containing toxic cardiac glycosides (primarily oleandrin). In this study, 50 lactating Fleckvieh cows were affected after being offered a diet containing dry oleander pruning wastes accidentally mixed with fodder. Clinical examination, electrocardiogram, and blood sampling were conducted. Dead animals were necropsied, and heart, liver, kidney, spleen, and intestine were submitted to histological investigation. Oleandrin detection was performed through ultra-high performance liquid chromatography-tandem mass spectrometry in blood, serum, liver, heart, milk, and cheese samples. Severe depression, anorexia, ruminal atony, diarrhea, serous nasal discharge, tachycardia, and irregular heartbeat were the most common clinical signs. The first animal died within 48 h, and a total of 13 cows died in 4 days. Disseminated hyperemia and hemorrhages, multifocal coagulative necrosis of the cardiac muscle fibers, and severe and diffuse enteritis were suggestive of oleander poisoning. The diagnosis was confirmed by the presence of oleandrin in serum, liver, heart, milk, and cheese. Our results confirm the high toxicity of oleander in cattle and report for the first time the transfer into milk and dairy products, suggesting a potential risk for the consumers.

Abstract
Introduction: Nerium oleander is a plant that is frequently grown in gardens and public areas. N. oleander is distributed originally in subtropical Asia but is now growing in many parts of the world, such as the United States, Australia, China, and Middle East countries. Pharmacological effects of plant including antinociceptive, anti-inflammatory, and anticancer activity were reported, but the potential toxic effects of all parts of the shrub either fresh or dried on animal and human body were documented. Method: The data of this review article were obtained from Medline/Pubmed, Scopusand Google Scholar databases in English until September 2019. To include all publications in this field, keywords such as N. oleander and toxicity were used. Results: The poisoning effects of plant or their active alkaloids induced infiltration of cells with hemorrhage and sever negative changes in the lung, induce lesions, and infiltration of inflammatory cells into the portal spaces with scattered necrosis of hepatocytes in the liver, cardiac toxicity of the plant in the heart were included, induced varying degrees of hemorrhage, myocardial degeneration, and necrosis. It also induced arrhythmia, sinus bradycardia, and prolonged P-R interval in electrocardiographic records. Conclusions: The toxic effects of N. oleander are mostly related to its inhibitory effects on the Na+-K+ ATPase pump in the cellular membrane. However, the exact molecular mechanism involved in the toxicity of N. oleander is not clear.

Abstract
Oleander (Nerium oleander) is an ornamental plant common in tropical and sub-tropical regions that is becoming increasingly widespread, even in temperate regions. Oleander poisoning may occur in animals and humans. The main active components contained in the plant are cardiac glycosides belonging to the class of cardenolides that are toxic to many species, from human to insects. This work describes a case of oleander poisoning that occurred on a small cattle farm and resulted in the fatality of all six resident animals. Furthermore, the investigation of the poisonous agent is described, with particular focus on the characterization of the oleandrin toxin that was recovered from the forage and rumen contents. The innovation of this study is the first description of the detection and quantification of the oleandrin toxin by liquid chromatography-high resolution mass spectrometry (LC-HRMS) in rumen.

Abstract
Nerium oleander (N. oleander) is a well-known poisonous shrub that is frequently grown in gardens and public areas and contains numerous toxic compounds. The major toxic components are the cardiac glycosides oleandrin and neriin. The aim of our study was to evaluate the toxic effects of an ethanolic N. oleander leaf extract on haematological, cardiac, inflammatory, and serum biochemical parameters, as well as histopathological changes in the heart. N. oleander extract was orally administered for 14 and 30 consecutive days at doses of 100 and 200 mg of dried extract/kg of body weight in 0.5 mL of saline. The results showed significant increases in mean corpuscular volume, white blood cell counts, platelet counts, interleukins (IL-1 and IL-6), tumour necrosis factor alpha, C reactive protein, alanine aminotransferase, lactate dehydrogenase, creatine kinase and creatine kinase MB, especially at high doses. Marked pathological changes were perceived in the heart tissue. Thus, it can be concluded that exposure to N. oleander leaf extract adversely affects the heart and liver.

Abstract
In the North Eastern region of Morocco, many people are interested in medicinal plants and their uses. However, the rationale for the utilization of medicinal plants has remained largely underestimated with little or no scientific data on plant safety. In this paper we attempt to describe and establish a detailed list of current knowledge in relation to the toxicity of these plants and to evaluate the scientific data concerning the harmful effects of the selected natural products. Our approach consists of collecting published data from literature in specialized journals, books and website related to the toxic plants. This research revealed that 89 plant species, retrieved from 287 plants used as medicine in the North-Eastern region of Morocco, are considered toxic or present some kind of toxicity. Our data determines 55 compounds isolated from the plants which are dominated by five groups of toxic compounds: alkaloids followed by glucosides, terpenoids, protides and phenolics. The present work discusses toxicity-related issues arising from the use of medicinal plants by local people. We conclude that the database considered in this study could serve as an important source of information on the toxicity of medicinal plants used by this society.
