FIELD: medicine, pharmaceutics. ^ SUBSTANCE: invention refers to pharmacology and medicine, namely to a method for producing diagnostic allergens of a number of synanthropic insects, such as: Blattella germanica, Blatta orientalis, Pertplaneta americana cockroach Neuphoeta cinerea, Musca domestica, Tinea pelionella, Cimex lectularis, Monomorium pharaonis, Tegenaria derhami, Culex pipiens, Attagenus Smirnovi Zhan. For the method for producing the diagnostic allergen, initial raw materials are frozen synanthropic insects. The initial raw materials are grinded to particle size 1-3 mm, degreased by addition of ether in the ratio 1:3-4 to the raw materials; the raw materials are kept in ether during 15-20 min that is followed by removal of ether by mixture filtering; the raw materials are degreased again by ether, dried to complete ether removal; the completely fat-free raw materials are powdered. The prepared powder is extracted in two stages; the first stage involves pouring the powder with an extractant liquid 1:1 and mixing to a homogeneous suspension; and the second stage includes mixing the prepared suspension with the extractant liquid in the ratio 2:1 and agitating by shaking the suspension three times for 30 minutes every 1.5 hours at temperature 2-10C for 3 days with daily correction of the pH value of the allergenic extract to 7.0-7.2. ^ EFFECT: invention provides extended range of the diagnostic allergens and creation of a highly effective preparation for the diagnostic diseases caused by sensitisation to synanthropic insects. ^ 2 cl, 1 ex, 1 tbl |
