China has already set up the poisonous biological sample storehouse The masses are still not enough when knowing

China has already set up the poisonous biological sample storehouse The masses are still not enough when knowing
The reporter sponsored from Beijing Botanical Garden and Center for Disease Prevention and Control, China of the Chinese Academy of Sciences on May 15 " The popular science exhibition of the poisonous plant " On know at present our country is getting more poisonous to be more set up already sample storehouses biological last blanks domestic and foreign. The poisonous plant is generally defined as can produce the plant on harmful function to people and domestic animal,etc.ing schematically. At a lot of time, it is distinguished that poisonous plant and medical plant are very difficult, a lot of medical plants are the poisonous plant at the same time, they have, treat function is and excessive to the toxic effect produces promptly under certain dosage, cause the human injury. Usually we classify plants that toxic function is obvious as the poisonous plant. For example poisonous the intersection of plant and croton can make cathartic, foreign digitalis can make cardiotonic, exceed certain consumption, can make people poison. There are more than 30,000 kinds of wild plants in our country at present, accounts for 10% of the total amount of resource of the world plant, among them, the quantity of the potential poisonous plant is about more than 9000 kinds (including planting the grade) ,And whom clear literature record only 1000 over in that, a lot of nearly the intersection of predestination and wild kind paid to classify lack corresponding toxic research, people are not enough to the poisonous understanding which is harmful to the plant at one's side. The human understanding of poisonous plant stems from life and production practices, through looking for the course of the food, medicine to accumulate the knowledge of getting up about the poisonous plant progressively, most known poisonous plants rely on this kind of experience material accumulated for a long time to offer at present. After the 19th century, were studied and launched gradually about the experiment of the poisonous plant. In near decades, employ modern organic chemistry and toxicologic method, make the research level of the poisonous plant improve a lot, deepen the chemical composition of the poisonous plant, understanding of poisoning mechanism progressively too. The relevant expert of Center for Disease Prevention and Control of China says, because there is not a special poisonous biological sample storehouse yet both at home and abroad at present, setting up the poisonous biological sample storehouse of our country can fill in this blank. Because the sample collects uncertainty, are closely related with with situations such as time, season, biological activity law,etc., so the sample is compiled it is the work of one longer cycle, the development of the sample storehouse should be trained and combined together in line with building, cooperating mechanism's setting up, team, follow in order and advance step by step, serve and develop the principle regarded as equally important, among them except that the regular sample is collected, poisonous substance that collect accumulation of sample whether the intersection of hygiene and field work work must be launchedded to deepen one of too in the incident.
