【預期用途】
尼古丁(Nicotine)是煙草中的主要生物堿,是導致吸煙成癮的物質動因,也是評價人體攝入煙草煙霧的常用指標。但因為尼古丁半衰期短,無法作為標志物檢測,其代謝物可替寧因為半衰期長作為吸煙和戒煙的標志物。
本品采用競爭抑制法和膠體金免疫層析技術,用于快速定性檢測人體唾液中的可替寧,適用于評價煙草煙霧攝入的初步篩查。

如檢驗標本為乳汁等含脂肪較多的材料,在涂片制成后,可先用二甲苯或細菌滴加覆蓋于涂片之上,經搖動lmin~2min脫脂后傾去,再滴加95%酒精以除去二甲苯,待酒精揮發后即可染色。3.2.1.2 染色
染色液配制方法見附錄B(標準的附錄)。
萎—尼氏抗酸染色:處理過的被檢材料涂片后,經火焰固定,加苯酚復紅染色液(見附錄B中B1)覆蓋,將玻片在火焰上加熱至出現蒸汽(不能產生氣泡),如此熱染5min(如染色液干涸,須加適量補充)。水洗后滴加3%鹽酸酒精(見附錄B中B2)脫色30s~60s(至無色素脫下為止)。水洗后,以駱氏美藍染色液(見附錄B中B3)復染lmin。水洗,吸干,鏡檢。抗酸菌應不被鹽酸酒精脫色而染成紅色,其他細菌與動物細胞可被鹽酸酒精脫色而均被染成藍色。3.2.1.3 鏡檢
結核分枝桿菌在顯微鏡下呈細長平直或微彎曲的桿菌,長1.5um~5um,寬0.2um~0.5um,在陳舊培養基上或干酪性淋巴結內的菌體,偶爾可見長達10um或更長。
3.2.2 培養3.2.2.1 培養基配制方法見附錄C(標準的附錄)。
3.2.2.2 被檢標本經消化濃縮后吸取其沉淀物作為培養材料。初次分離,可用配氏培養基(見附錄C中C1)、L-J培養基(見附錄C中C2)或青霉素血液瓊脂培養基(見附錄C中C3)。
3.2.2.3 將經過處理的標本接種到培養基上(同時作2~4份),培養一天后、以熔化的石蠟封口,繼續培養。3.2.2.4 牛型結核分枝桿菌比人型結核分枝桿菌生長要緩慢得多。初次培養牛型結核分枝桿菌時,需36℃-37℃培養5-8周方可出現菌落。在固定培養基上不產生任何顏色,菌落濕潤、略顯粗糙并發脆。加1%的丙酮酸鈉能促進生長,但在噻吩-2酸肼(T2H)培養基(見附錄C中C4)上不生長。
3.2.2.5 禽型結核分枝桿菌生長需要2~3周。形成濕潤、彌漫狀,光滑及星光狀菌落。zui適生長溫度為40℃—42℃。在 T2H培養基上生長。
3.2.2.6 人型結核分枝桿菌生長需要36℃~37℃培養3~4周。該菌落干燥、粗糙,呈白色、黃色或橙色。牢牢附著于培養基。在T2H培養基上生長。

If the test specimen is more fat-containing materials such as milk, after the smear is made, it may be coated with xylene or bacteria dripping over the smear, degreased by lmin ~ 2min, and then dripped 95 % Alcohol to remove xylene, until the alcohol can be evaporated after staining. 3.2.1.2 staining
Preparation of staining solution see Appendix B (standard appendix).
Wilt - Nissl Acid-Resistant Staining: After the treated material is smeared, it is flame-fixed and covered with a phenol red complex stain (see B1 in Appendix B). The glass slide is heated on a flame until steam is generated Bubbles), so hot dye 5min (such as the drying of the stain, to be added to the appropriate amount). After washing 3% hydrochloric acid drops (see Appendix B in B2) decolorization 30s ~ 60s (until no pigment off date). After washing, counterstain with lumex methylene blue stain (see Appendix B B3) lmin. Washed, dry, microscopic examination. Acid-fast bacteria should not be discolored by hydrochloric acid and be colored red. Other bacteria and animal cells may be discolored by hydrochloric acid and be dyed blue. 3.2.1.3 Microscopy
Mycobacterium tuberculosis under the microscope was elongated flat or slightly curved bacilli, length 1.5um ~ 5um, width 0.2um ~ 0.5um, bacteria in the old medium or cheese lymph nodes, and occasionally up to 10um Or longer.
3.2.2 Culture 3.2.2.1 Medium preparation method see Appendix C (standard appendix).
3.2.2.2 After the specimen was digested and concentrated to absorb the sediment as culture material. Primary separation may be performed on the same medium (see C1 in Annex C), L-J medium (see C2 in Appendix C), or penicillin blood agar (see C3 in Appendix C).
3.2.2.3 The treated specimens inoculated into the medium (also made 2 to 4 copies), after a day of c*tion, sealed with melted paraffin, and continue to culture. 3.2.2.4 Mycobacterium bovis is much slower than human M. tuberculosis. For the first time when the bovine Mycobacterium tuberculosis is c*ted, colonies should be cultured for 5-8 weeks at 36 ℃ -37 ℃. No color on fixed media, colonies wet, slightly rough and crisp. Addition of 1% sodium pyruvate promotes growth but does not grow in thiophene-2-hydrazine (T2H) medium (see C4 in Appendix C).
3.2.2.5 Mycobacterium tuberculosis growth of birds takes 2 to 3 weeks. Form moist, diffuse, smooth and star-shaped colonies. The most suitable growth temperature is 40 ℃ -42 ℃. Grow on T2H medium.
3.2.2.6 human Mycobacterium tuberculosis growth needs 36 ℃ ~ 37 ℃ for 3 to 4 weeks. The colonies are dry, rough, white, yellow or orange. Firmly attached to the medium. Grow on T2H medium.
