Genetic identification and subsequent LC-QTOF MS analysis of plant remains (Oenanthe spp.) could prove the cause of an undetermined sudden death.

Int J Legal Med 2021 Jan 27. Epub 2021 Jan 27.

Galician Institute of Legal Medicine and Forensic Science, IMELGA, Lalín 4, 36209, Vigo, Spain.

In recent years, recorded cases related to forensic botany and, in particular, of plant poisoning have become rare. We report on the medicolegal characteristics of an undetermined sudden death (USD) of a woman in which scene there were remnants of a vegetal peeling. After the autopsy, macroscopic findings reported multiorgan failure and requested the investigation of the cause of death. Read More

G Ital Nefrol 2020 Apr 9;37(2). Epub 2020 Apr 9.

Divisione di Nefrologia, Ospedale Miulli, Acquaviva delle Fonti, Bari, Italia; Associazione Nefrologica Gabriella Sebastio, Martina Franca, Taranto, Italia.

Rhabdomyolysis (R) is a complex condition involving the rapid dissolution of damaged or injured skeletal muscle. This leads to the direct release of intracellular components, including myoglobin, creatine kinase, aldolase, and lactate dehydrogenase, as well as electrolytes, into the bloodstream and extracellular space. Clinically, R shows a triad of symptoms: myalgia, limb weakness, and myoglobinuria without hematuria, while myoglobin has been recognized as playing a part in the development of acute kidney injury.

Alkaloid-Containing Plants Poisonous to Cattle and Horses in Europe.

Toxins (Basel) 2015 Dec 8;7(12):5301-7. Epub 2015 Dec 8.

Department of Health, Animal Science and Food Safety (VESPA), Università degli Studi di Milano, Via Celoria 10, 20133 Milan, Italy.

Alkaloids, nitrogen-containing secondary plant metabolites, are of major interest to veterinary toxicology because of their occurrence in plant species commonly involved in animal poisoning. Based on epidemiological data, the poisoning of cattle and horses by alkaloid-containing plants is a relatively common occurrence in Europe. Poisoning may occur when the plants contaminate hay or silage or when forage alternatives are unavailable. Read More

Poisonous plants: effects on embryo and fetal development.

Birth Defects Res C Embryo Today 2013 Dec;99(4):223-34

USDA-Agricultural Research Service, Poisonous Plant Research Laboratory, 1150 East 1400 North, Logan, Utah, 84341.

Poisonous plant research in the United States began over 100 years ago as a result of livestock losses from toxic plants as settlers migrated westward with their flocks, herds, and families. Major losses were soon associated with poisonous plants, such as locoweeds, selenium accumulating plants, poison-hemlock, larkspurs, Veratrum, lupines, death camas, water hemlock, and others. Identification of plants associated with poisoning, chemistry of the plants, physiological effects, pathology, diagnosis, and prognosis, why animals eat the plants, and grazing management to mitigate losses became the overarching mission of the current Poisonous Plant Research Laboratory.

Water hemlock poisoning in cattle: Ingestion of immature Cicuta maculata seed as the probable cause.

Toxicon 2011 Jan 20;57(1):157-61. Epub 2010 Nov 20.

USDA ARS Poisonous Plant Research Laboratory, 1150 E. 1400 N., Logan, UT 84341, USA.

It is well understood that water hemlock tubers are highly toxic to animals and to humans. However, this is the first time that immature seed from (Cicuta maculata) has been implicated in livestock poisoning. Nine mature Hereford cows from a herd of 81 died in northwestern Utah after ingesting immature seed heads of water hemlock (Cicuta maculata) in late summer. Read More

What killed Socrates? Toxicological considerations and questions.

Authors:
A D Dayan

Postgrad Med J 2009 Jan;85(999):34-7

The death of Socrates in 399 BCE, as reported by Plato in the Phaedo, is usually attributed to poisoning with common hemlock. His progressive centripetal paralysis is characteristic of that poison. Socrates is said to have had a prominent loss of sensation extending centrally from his legs, which is not a feature of hemlock poisoning, and he seems not to have had the unpleasant taste or common gastrointestinal effects of that poison.

Food Chem Toxicol 2004 Sep;42(9):1373-82

Faculty of Veterinary Science, Department of Botany, Szent István University, 1400 Budapest, Pf. 2. Hungary.

One of the most poisonous species amongst higher plants is Conium maculatum. It is a very common nitrophile weed species, belonging to the Apiaceae (formerly Umbelliferae) family. It contains some piperidine alkaloids (coniine, N-methyl-coniine, conhydrine, pseudoconhydrine, gamma-coniceine), which are formed by the cyclisation of an eight-carbon chain derived from four acetate units.
