Coturnism
Coturnism is an illness featuring muscle tenderness and rhabdomyolysis (muscle cell breakdown) after consuming quail (usually common quail, ''Coturnix coturnix'', from which the name derives) that have fed on poisonous plants. Causes From case histories it is known that the toxin is stable, as four-month-old pickled quail have been poisonous. Humans vary in their susceptibility; only one in four people who consumed quail soup containing the toxin fell ill. The toxin is apparently fat-soluble as potatoes fried in quail fat have proven poisonous themselves. Coniine from hemlock consumed by quail has been suggested as the cause of coturnism, though quail resist eating hemlock. Hellebore has also been suggested as the source of the toxin. It has also been asserted that this evidence points to the seeds of the annual woundwort (''Stachys annua'') being the causal agent. It has been suggested that ''Galeopsis ladanum'' seeds are not responsible. Epidemiology Migration routes and sea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aristotle
Aristotle (; grc-gre, Ἀριστοτέλης ''Aristotélēs'', ; 384–322 BC) was a Greek philosopher and polymath during the Classical period in Ancient Greece. Taught by Plato, he was the founder of the Peripatetic school of philosophy within the Lyceum and the wider Aristotelian tradition. His writings cover many subjects including physics, biology, zoology, metaphysics, logic, ethics, aesthetics, poetry, theatre, music, rhetoric, psychology, linguistics, economics, politics, meteorology, geology, and government. Aristotle provided a complex synthesis of the various philosophies existing prior to him. It was above all from his teachings that the West inherited its intellectual lexicon, as well as problems and methods of inquiry. As a result, his philosophy has exerted a unique influence on almost every form of knowledge in the West and it continues to be a subject of contemporary philosophical discussion. Little is known about his life. Aristotle was born in th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bird Problems With Humans
Birds are a group of warm-blooded vertebrates constituting the class Aves (), characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweight skeleton. Birds live worldwide and range in size from the bee hummingbird to the ostrich. There are about ten thousand living species, more than half of which are passerine, or "perching" birds. Birds have whose development varies according to species; the only known groups without wings are the extinct moa and elephant birds. Wings, which are modified forelimbs, gave birds the ability to fly, although further evolution has led to the loss of flight in some birds, including ratites, penguins, and diverse endemic island species. The digestive and respiratory systems of birds are also uniquely adapted for flight. Some bird species of aquatic environments, particularly seabirds and some waterbirds, have further evolved for swimming. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quails
Quail is a collective name for several genera of mid-sized birds generally placed in the order Galliformes. The collective noun for a group of quail is a flock, covey, or bevy. Old World quail are placed in the family Phasianidae, and New World quail are placed in the family Odontophoridae. The species of buttonquail are named for their superficial resemblance to quail, and form the family Turnicidae in the order Charadriiformes. The king quail, an Old World quail, often is sold in the pet trade, and within this trade is commonly, though mistakenly, referred to as a "button quail". Many of the common larger species are farm-raised for table food or egg consumption, and are hunted on game farms or in the wild, where they may be released to supplement the wild population, or extend into areas outside their natural range. In 2007, 40 million quail were produced in the U.S. New World *Genus ''Callipepla'' **Scaled quail, (commonly called blue quail) ''Callipepla squamata'' **E ...

Toxic Effect Of Noxious Substances Eaten As Food
Toxicity is the degree to which a chemical substance or a particular mixture of substances can damage an organism. Toxicity can refer to the effect on a whole organism, such as an animal, bacterium, or plant, as well as the effect on a substructure of the organism, such as a cell (cytotoxicity) or an organ such as the liver (hepatotoxicity). By extension, the word may be metaphorically used to describe toxic effects on larger and more complex groups, such as the family unit or society at large. Sometimes the word is more or less synonymous with poisoning in everyday usage. A central concept of toxicology is that the effects of a toxicant are dose-dependent; even water can lead to water intoxication when taken in too high a dose, whereas for even a very toxic substance such as snake venom there is a dose below which there is no detectable toxic effect. Toxicity is species-specific, making cross-species analysis problematic. Newer paradigms and metrics are evolving to bypass a ...

Conium
''Conium'' ( or ) is a genus of flowering plants in the family Apiaceae. , Plants of the World Online accepts six species. All species of the genus are poisonous to humans. ''C. maculatum'', also known as hemlock, is infamous for being highly poisonous. Hemlock is native to temperate regions of Europe, North Africa and Western Asia. The species ''C. chaerophylloides'', ''C. fontanum'', and ''C. sphaerocarpum'' are all native to southern Africa. Description Plants of the genus ''Conium'' are eudicots, flowering plants distinguished by their two cotyledons (embryonic leaves) and tricoplate (three-pored) pollen. They are typically biennial, forming basal rosettes in the first year of growth, and sprouting a rigid, hollow flower stalk in the second. Germination occurs between spring and autumn. Occasionally, plants which germinate in early spring are annual instead of biennial. These plants grow best in wet, poorly drained areas with nutrient rich soil. They grow well in nitrogen ...

Henbane
''Hyoscyamus niger'', commonly known as henbane, black henbane, or stinking nightshade, is a poisonous plant in the nightshade family Solanaceae. It is native to temperate Europe and Siberia, and naturalised in Great Britain and Ireland. Historical use The name ''henbane'' dates at least to AD 1265. The origins of the word are unclear, but "hen" probably originally meant death rather than referring to chickens. Other etymologies of the word associate it with the Indo-European stem ''*bhelena'' whose hypothetical meaning is 'crazy plant' and with the Proto-Germanic element ''bil'' meaning ‘vision, hallucination; magical power, miraculous ability’. Henbane was historically used in combination with other plants, such as mandrake, deadly nightshade, and datura, as an anaesthetic potion, as well as for its psychoactive properties in "magic brews". These psychoactive properties include visual hallucinations and a sensation of flight.Schultes & Smith 1976, p. 22 It was originally ...

Hellebore
Commonly known as hellebores (), the Eurasian genus ''Helleborus'' consists of approximately 20 species of herbaceous or evergreen perennial flowering plants in the family Ranunculaceae, within which it gave its name to the tribe of Helleboreae. Despite names such as "winter rose", "Christmas rose" and "Lenten rose", hellebores are not closely related to the rose family (Rosaceae). Many hellebore species are poisonous. Description The flowers have five petal-like sepals surrounding a ring of small, cup-like nectaries which are actually petals modified to hold nectar. The sepals do not fall as petals would, but remain on the plant, sometimes for many months. Recent research in Spain suggests that the persistence of the sepals contributes to the development of the seeds. Taxonomy The genus was established by Carl Linnaeus in volume one of his ''Species Plantarum'' in 1753. The scientific name ''Helleborus'' could derive from the Ancient Greek word (), the common name for '' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sextus Empiricus
Sextus Empiricus ( grc-gre, Σέξτος Ἐμπειρικός, ; ) was a Ancient Greece, Greek Pyrrhonism, Pyrrhonist philosopher and Empiric school physician. His philosophical works are the most complete surviving account of ancient Greek and Roman Pyrrhonism, and because of the arguments they contain against the other Hellenistic philosophy, Hellenistic philosophies, they are also a major source of information about those philosophies. In his medical work, as reflected by his name, tradition maintains that he belonged to the Empiric school in which Pyrrhonism was popular. However, at least twice in his writings, Sextus seems to place himself closer to the Methodic school. Little is known about Sextus Empiricus. He likely lived in Alexandria, Rome, or Athens. The ''Suda,'' a 10th-century Byzantine encyclopedia, states that he was the same person as Sextus of Chaeronea, as do other pre-modern sources, but this identification is commonly doubted.

Galen
Aelius Galenus or Claudius Galenus ( el, Κλαύδιος Γαληνός; September 129 – c. AD 216), often Anglicized as Galen () or Galen of Pergamon, was a Greek physician, surgeon and philosopher in the Roman Empire. Considered to be one of the most accomplished of all medical researchers of antiquity, Galen influenced the development of various scientific disciplines, including anatomy, physiology, pathology, pharmacology, and neurology, as well as philosophy and logic. The son of Aelius Nicon, a wealthy Greek architect with scholarly interests, Galen received a comprehensive education that prepared him for a successful career as a physician and philosopher. Born in the ancient city of Pergamon (present-day Bergama, Turkey), Galen traveled extensively, exposing himself to a wide variety of medical theories and discoveries before settling in Rome, where he served prominent members of Roman society and eventually was given the position of personal physician to several emp ...

Lucretius
Titus Lucretius Carus ( , ; – ) was a Roman poet and philosopher. His only known work is the philosophical poem ''De rerum natura'', a didactic work about the tenets and philosophy of Epicureanism, and which usually is translated into English as ''On the Nature of Things''—and somewhat less often as ''On the Nature of the Universe''. Lucretius has been credited with originating the concept of the three-age system that was formalised in 1836 by C. J. Thomsen. Very little is known about Lucretius's life; the only certainty is that he was either a friend or client of Gaius Memmius, to whom the poem was addressed and dedicated. ''De rerum natura'' was a considerable influence on the Augustan poets, particularly Virgil (in his ''Aeneid'' and ''Georgics'', and to a lesser extent on the ''Eclogues'') and Horace. The work was almost lost during the Middle Ages, but was rediscovered in 1417 in a monastery in Germany by Poggio Bracciolini and it played an important role both ...

Philo
Philo of Alexandria (; grc, Φίλων, Phílōn; he, יְדִידְיָה, Yəḏīḏyāh (Jedediah); ), also called Philo Judaeus, was a Hellenistic Jewish philosopher who lived in Alexandria, in the Roman province of Egypt. Philo's deployment of allegory to harmonize Jewish scripture, mainly the Torah, with Greek philosophy was the first documented of its kind, and thereby often misunderstood. Many critics of Philo assumed his allegorical perspective would lend credibility to the notion of legend over historicity. Philo often advocated a literal understanding of the Torah and the historicity of such described events, while at other times favoring allegorical readings. Though never properly attributed, Philo's marriage of Jewish exegesis and Stoic philosophy provided a formula later picked up by other Midrash content from the 3rd and 4th centuries. Some claimed this lack of credit or affinity for Philo by the Rabbinic leadership at the time, was due to his adoption of alle ...
