Эндометриоз представляет собой доброкачественное хроническое гинекологическое заболевание. Его можно определить как присутствие эндометриальной ткани, содержащей как железистый эпителий, так и строму, вне полости матки. Он является доброкачественным гинекологическим расстройством, которое в субпопуляции пациентов женского пола может развиваться в агрессивное заболевание. Эндометриоз ассоциирован с различными болезненными симптомами, включая дисменорею, диспареунию, тазовую боль и сниженную фертильность. Потенциальную эффективность антиангиогенной терапии для лечения эндометриоза оценивали с применением исследования с использованием человеческих эндометриальных тканей, трансплантированных бестимусным мышам с ослабленным иммунитетом. Четыре различных антиангиогенных ангента вводили через три недели после трансплантации эндометриальных эксплантатов Nap et al,
Ergot Alkaloids – an ancient story
Ergot alkaloids are a large group of compounds produced by fungi that attack a wide variety. These compounds are. Two common alkaloids examined for in ergot are ergotamine and ergovaline. The major ergot fungus is Claviceps which produces sclerotia in several grass species with C.
However, C. Ergot does occur in sorghum and is caused by the organism Sphacelia sorghi. While other fungi are also capable of producing ergot alkaloid these are the major species that are producers of ergot in grain.
The sclerotia are brown to purple-black in color and contain the ergot alkaloids. The fungus gains entry into the host plant from ergots that have been in the soil. The infecting fungal elements are assisted by wind and splashing rain in gaining access to the host plant where the florets are invaded with subsequent development of sclerotia. The fungus uses nutrients from the plant for development of the ergots and biosynthesis of the ergot alkaloids.
The ergots are harvested with the grain and if not eliminated by screening or some other process they can end up in feed or food made from the contaminated grain.
Ergot is not a storage initiated problem but the ergots can be present in stored grains resulting from harvesting of ergots along with the grain. Ergotism is one of the oldest known mycotoxicoses with ancient records of its occurrence. One of the most publicized events was the human epidemics produced by ergot in the Middle Ages known as St. Animals are affected similarly to what has been observed in humans.
In swine agalactia has been attributed to ergot alkaloids. The loss of ears and other appendages is a common effect of ergot in animals. Two types of ergotism have been described; gangrenous and convulsive.
The differences may be due to the different kinds of alkaloids present in the ergot as variations in amount and kinds of alkaloids can occur in the ergot sclerotia. Recent outbreaks have occurred in Ethiopia where gangrene and loss of limbs occurred and in India where the effects were more of the nervous type symptoms of giddiness, drowsiness, nausea and vomiting. Ergometrine was the alkaloid found in the Ethiopian sclerotia and in India the clavine alkaloids agroclavine, elymoclavine, chanoclavine, penniclavine and setoclavine were found.
The ergots produced in these two outbreaks were caused by different species of Claviceps. Because some of the ergot alkaloids are vasoconstrictive and have other beneficial pharmacological properties, they have been used therapeutically. In the United States, most of the widely grown tall fescue posesses an endophytic fungus called Neotyphodium coenophialum.
This endophyte produces ergovaline, an ergopeptine, which can, if consumed levels are sufficient, produce ergot-like toxicosis in animals grazed on pastures containing the fescue grass CAST, Check out our Ergot Alkaloid Solutions.

What are Ergot Alkaloids? Дата: Автор: John L. LinkedIn Twitter Facebook Email. Ergot alkaloids are a large group of compounds produced by fungi that attack a wide variety of grass species, including small grains, during the growing season. These compounds are chemically divided into the clavine alkaloids, lysergic acids, simple lysergic acid amides and peptide alkaloids.

Ergot alkaloids are secondary metabolites usually produced by fungi belonging to the genus Claviceps. The most commonly occurring species producing ergot alkaloids is Claviceps purpurea. Many different cereal plants and grasses, including rye, wheat and triticale among others, can become infected by these fungi during cool, wet weather conditions. These fungi then produce structures called sclerotia. These sclerotia contain different classes of ergot alkaloids, the most prominent being ergometrine, ergotamine, ergosine, ergocristine, ergocryptine and ergocornine together with their epimeric —inine forms.
