四圜素研究成功四圜素已由化工部上海医药工业研究所研究成功,并将移交制药厂进行大量生产。四圜素是属于四圜类的抗生素之一,在抗菌谱及药理作用上和金霉素非常相似。近年来,国外对四圜素作了各种试验,证明该品对肺炎、外科感染、斑疹伤寒、痢疾、鹦鹉病等都有特效。四圜素的毒性较金霉素为低,临床上发现的副作用如呕吐、恶心及腹泻等胃肠 Tetramethine has been successfully studied by Shanghai Pharmaceutical Industry Research Institute of the Ministry of Chemical Industry and will be transferred to pharmaceutical plants for mass production. Tetramethine is one of the antibiotics belonging to the tetraterpenoids, and is very similar to chlortetracycline in terms of antibacterial spectrum and pharmacological effects. In recent years, various tests have been conducted abroad on Tetrahedrin to prove that the product has special effects on pneumonia, surgical infections, typhus, dysentery, and parrot diseases. Tetramethine is less toxic than chlortetracycline and has clinical side effects such as vomiting, nausea, and diarrhea.
