“…of 20 µg Kg −1 of body weight and has been associated with animal toxicosis in several countries (Patoka et al, 2011). Clinical signs of nicotinic receptor overstimulation are most commonly observed before a lethal outcome, including a rapid onset of hypersalivation, lacrimation, tremors, incoordination, convulsions, urinary incontinence and respiratory arrest (Cook et al, 1989;Matsunaga et al, 1989;Puschner & Roegner, 2012). Further studies are needed to understand if this natural toxin, which is similar in its action to the chemical sarin and soman weapons, could be used in the future with a more beneficial purpose such as MG management.…”

Cyanotoxins: from poisoning to healing -a possible pathway? Cyanobacteria are photosynthetic microorganisms known for their multiple, and occasionally dual, ecologic roles. Cyanobacteria are major contributors to oxygen production on earth, but they often bloom in freshwater environments, depleting oxygen and inducing massive fish kills by anoxia. In addition, cyanobacteria are primary producers and the base of the food web in aquatic ecosystems, but they often "crowd out" other phytoplanktonic organisms by competing for nutrients. Cyanobacteria produce an array of beneficial, biologically active compounds, but some of their secondary metabolites are also known to be highly toxic to humans. Many cyanobacterial characteristics are still a mystery and raise many unsolved questions: Why do they bloom? How do they "communicate" with each other and "synchronise" to flourish? How do they colonise so many diverse habitats and are resistant to the most adverse of environments? Why do some strains produce toxins while others do not? Current research on cyanobacteria may provide answers to these "old" questions, but may also challenge us to consider new perspectives. In this paper, we will discuss the potential therapeutic application of cyanobacterial toxins, most of which are known as potent toxicants, but some of which have a non-negligible potential for drug discovery.

Seafood poisoning is the foodborne illness associated with the consumption of shellfish and fish that contain toxins. Shellfish toxins are produced by certain dinoflagellate species. Bivalve shellfish, especially mussels, clams and oyster can accumulate so many toxins by ingesting with filter-feeding. Shellfish have mechanisms that prevent the hazardous effects of these toxins. Although the toxins do apparently not harm the shellfish and fish, humans eating toxic seafood may become poisoned. These toxins can not be eliminated by cooking procedures. Toxins that cause poisining on fish are produced by spoilage bacteria. The deterioration of fish (tuna, sardine etc.) causes toxins to occur. Seafood poisoning (paralytic shellfish poisoning (PSP), ciguatera poisoning, scombroid poisoning, etc.) is a serious illness and the toxins (saxitoxin, tetrodotoxins, etc.) that are responsible for this illness pose a great risk to seafood safety and public health. Paralytic shellfish poisoning (PSP) and scombroid poisoning are common seafood toxicity problems. The inability of finding an antidote for seafood poisoning makes this foodborne illness even more serious. By waiting shellfish in clean water to obtain the reduction on toxin levels can be the solution for protection from poisoning. In this review, the characteristics of toxins and their effects on human health are discussed. Keywords SU ÜRÜNLERİ TOKSİNLERİ VE ZEHİRLENMELERİ ÖZSu ürünleri zehirlenmeleri, toksinleri içeren balık ve kabuklu su ürün-lerinin tüketimiyle oluşan besin kaynaklı hastalıktır. Kabuklu su ürünleri toksinlerini bazı dinoflagellata türleri üretirler. Çift kabuklular, özellikle midye, istiridye ve deniz tarağı süzerek beslenme yaparak birçok toksini biriktirirler. Kabuklu su ürünleri, bu toksinlerin tehlikeli etkilerini önle-yici mekanizmaya sahiptir. Toksinlerin kabuklu su ürünlerinde ve balık-larda zararlı etkilerinin olmamasına rağmen, toksin içeren su ürünlerini yiyen kişiler için zehirli olabilir. Bu toksinler, pişirme işlemleri ile giderilemezler. Balık zehirlenmesine sebep olan toksinler bozulma bakterileri tarafından üretilir. Balık (tuna, sardalya vb.) bozulması toksinlerin ortaya çıkmasına sebep olur. Su ürünleri zehirlenmeleri (paralitik kabuklu su ürü-nü zehirlenmesi (PSP), ciguatera balık zehirlenmesi, skombroid zehirlenmesi, vb.) ciddi bir hastalıktır ve bu hastalığın sorumlusu olan toksinler (saksitoksin, tetradotoksin, vb.), su ürünleri güvenliği ve halk sağlığı için büyük bir risk yaratır. Paralitik kabuklu su ürünü zehirlenmesi (PSP) ve skombroid zehirlenmesi, en sık görülen su ürünleri zehirlenmeleridir. Su ürünleri zehirlenmesi için bir antidot bulunmaması, bu besin kaynaklı hastalığı daha da ciddi şekle getirir. Kabuklu su ürünleri toksin seviyelerinin azalması için, temiz suda bekletme, zehirlenmeden korunmak için çözüm olabilir. Bu incelemede, toksinlerin karakteristikleri ve insan sağlığına etkileri tartışılmıştır.Anahtar kelimeler: Su ürünleri toksinleri, kabuklu su ürünleri, balık, su ürünleri zehirlenmeleri.
