Where to buy cyproheptadine without a prescription
The hemolymph of the closely related species Leptinotarsa haldemani contains a toxin called β-leptinotoxin-h. Leptinotarzin is not accumulated with food, but is a natural protein of the beetle hemolymph. The toxin is quite resistant to the action of proteolytic enzymes, however, incubation with the body homogenate of the Colorado potato beetle completely inactivates it. Apparently, the body of the beetle has a detoxifying system. Leptinotarzine has an effect on neuromuscular transmission in vertebrates.
At concentrations of 10-11-10-10 mol/l, leptinotoxin-h enhances the entry of Ca 2+ into rat brain synaptosomes, and is also capable of releasing mediators from preloaded synaptosomes. This effect is also observed in a calcium-free medium, but calcium accelerates it. Under the action of leptinotoxin-h, fusion of vesicles and the formation of large membrane folds are observed in synaptosomes. In neurosecretory cells, a decrease in the number of secretory granules was noted. Apparently, the toxin stimulates the process of exocytosis. The hemolymph of the Colorado potato beetle is low toxic.
The phenomenon of blood squirting of toxic hemolymph is used not only by blisters, but also by other beetles. The well-known ladybugs (family Coccinellidae) in danger secrete droplets of colored hemolymph from the joints, which have a nasty taste for humans, which are given to it by the bitter alkaloids adalen and coccinellin. Aqueous solutions of ladybug hemolymph are toxic to vertebrates and invertebrates when injected. However, the toxicity of the contact method depends on the condition of the skin. When homogenate from the gourd Epilachna chrysomelina (Fig. 40) is rubbed into human skin, pronounced dermatitis is observed only with a preliminary skin lesion, while intact skin is resistant to the action of hemolymph.
The poisonous apparatus of the bombardier beetle (Fig. 42) consists of a gland connected by a duct to a reservoir in which aqueous solutions of hydrogen peroxide and hydroquinones accumulate. Through a narrow duct, equipped with a muscular sphincter, these substances enter the outer chamber, which communicates with the external environment. The cells of the walls of the outer chamber secrete the enzymes catalase and peroxidase. A portion of the substrate (hydroquinone, methylhydroquinone, hydrogen peroxide) is squeezed out into the outer chamber, where an explosive reaction takes place instantly. Catalase decomposes hydrogen peroxide into water and molecular oxygen, and peroxidase oxidizes hydroquinones to the corresponding quinones.

Under the pressure of the resulting gases, the mixture is fired in the form of cyproheptadine pills at a temperature. Many beetles defend themselves by spraying caustic or toxic substances. For example, dark beetles and ground beetles secrete benzoquinones and toluquinones. Dytiscus swimming beetles secrete a milky fluid containing 11-deoxycorticosterone, a precursor of aldosterone in vertebrates. Under its influence, fish develop a violation of water-salt metabolism and osmotic balance up to a state of shock. Paederus-dermatitis - an allergic reaction to blood beetles of the genus Paederus, characterized by vezikulezny dermatitis.

In mild cases, there is an absence of periactin pills, which begins at 12 - 36 hours, blisters and peeling appear, the effect is from a week to three. In severe cases, erythema, blistering, and pigmented scarring tend to be more extensive. possible additional symptoms. high fever, neuralgia, arthralgia and vomiting. Possible secondary infection. When the beetle of blood and conjunctiva / or cornea, usually through contaminated hands can be painful swelling and purulent conjunctivitis, known as Nairobi eye (Nairobi eye) "Nairobi eye". corneal erosion and blindness may occur.

Representatives of the genera T-shirts (Meloe), Spanish flies (Lytta), blisters (Mylabris) are characterized by toxic properties. T-shirts have a large, massive body, short elytra, and a long abdomen. Usually black with a bluish tint or purple. In the spring they meet in open places. They parasitize bees. There were over 40 species in the former USSR, including Meloe violaceus March.
