Lidocaine 으로 발생한 천식성 호흡발작 1 례 보고
권영석,안동애,권용임,김인현 대한마취과학회 1981 Korean Journal of Anesthesiology Vol.14 No.4
Lidocaine is considered a safe and effective local anesthetic in anesthesiology and is the stardard to which new amide anesthetics are compared. As it an amide derivative, and the frequrncy with lidocaine eliets an allergic respone is much less than that of anesthetics derived from paraaminobenroic acid esters. Case reports od sensitivity to lidoeaine have been reported, but h tey are rare. This 29 year old male patient had on episode of astmatic breathing after supraclavicular brachial plexus block using 30 ml of 1% lidocaine with epinephrine(1:200,000). We report a case of aesthmetic breating due to lidocaine and a review of the literature for allergy local anesthetics.

Coloring을 활용한 여학생 친화 생명과학 학습 자료를 개발하여, 고등학교의 1ㆍ2학년 여학생들을 대상으로 적용해 보았더니 ⑴ 기억ㆍ이해ㆍ적용ㆍ분석ㆍ종합ㆍ평가의 정신기능이 더욱 활발하게 되었고, ⑵ 생명과학 공부를 어려워하지 않으며 흥미와 관심이 좋아지게 되었으며, ⑶ 자연계와 기술ㆍ공학 분야에 많은 관심을 보였고, ⑷ 우수한 여학생들이 생명과학 관련 직업으로 진출할 의사를 가지게 되었다.

국내 재배 당근 품종은 대부분 수입에 의존하고 있어 국내 당근산업의 기반을 유지하고 경쟁력 확보를 위하여 우수한 품종을 개발 보급하고자 본 ‘그라운드 킹’을 육성하였다. 근형은 원추형이고, 근피색, 근육색 및 심색은 주황색으로 근피가 매끈하다. 숙기는 중만생종이고, 육질이 연하고 수분이 많다. 병해 저항성은 검은잎마름병 및 흰가루병이 중간 정도로 대비품종인 ‘양면’과 비슷하고, 추대에 다소 약하므로 조기 파종 할 때 추대 위험이 있다. 수량은 3,228 kg/10a이고, 근장은 16.3 cm, 근중은 171.0 g으로 대비품종 ‘양면’ 166.5 g과 비슷하다. 추대율은 3.9%로 양면 5촌의 2.4%보다 다소 높아 조기 파종시 추대의 위험이 있으므로 적기에 파종하여야 한다. A new carrot F1 hybrid cultivar,‘Ground King’ was developed from the cross between a male sterile line ‘80027A’ as a female parent and ‘804229’ as a male parent in 2003. Regional yield trial was carried out at five different provinces and three cultivation types from 2006 to 2008. The plant growth habit is erect and the root type is cone-shaped like ‘Yangmeon’ cultivar. Maturity belonged to a late-maturity type. It grows up to 59.3 cm in height and the average leaf number of a single plant is 9.4. Root color is all scarlet for skin, flesh and core. Regarding to disease resistance, it showed medium resistance to leaf blight and powdery mildew. The average root weight of ‘Ground King’ is very high as 171 g in compared with that of a commercial ‘Yangmyeon’ as 166 g. This variety will be optimal for spring and summer cultivation since the bolting ratio combe as low as 3.9%.
Effects of Bolting and Flower Stem Removal on the Growth and Chemical Qualities of Onion Bulbs

The growth of a flower stem (bolting) causes a decrease in yield and marketability in onion. We have examined the effects of bolting and of the removal of flower stems at different lengths on the growth and chemical qualities of onion bulbs. Two onion cultivars, ‘Mapshihwang’ (M) and ‘Yeongmihwang’ (Y), were grown in the field and allowed to bolt. The treatments included the removal of three different lengths of the flower stem (short, medium, or long), uncut flower stem until harvest, or unbolted plants (control). Bolting and the length of the flower stem removed had no effect on bulb diameter but caused a decrease in bulb weight. The flower stems were generated after three to five scales; bolting and flower stem removal reduced the number of scales by approximately one scale. The total soluble solid content (SSC) and the total sugar content were also unaffected by bolting and the length of the flower stem removed. The pungency of the M and Y cultivars, being an average of about 5.0 and 2.8 μmol·mL-1 pyruvic acid, respectively, was not changed. The total quercetin content showed various responses to the treatments and no clear differences compared to the unbolted bulbs. The total phenolic content was not changed by bolting or the stem removal treatments. In conclusion, bolting and removal of the flower stem caused a decrease in bulb weight, whereas the SSC, total sugar content, pungency, quercetin content, and total phenolic content remained unaffected, indicating that the chemical qualities of the bolted bulbs was identical to those of the unbolted, normal bulbs. The removal time of the flower stem had no significant difference on bulb quality.

Along with fast swelling of industrial facilities problem for heavy metals that increase day by day is risen by serious social problem now. Heavy metals of included vast quantity are accelerating damage of water area ecosystem because is flowed in more than self-cleansing power in rivers or lake in wastewater of this. According as discharge test for wastewater is solidified, interest about a technology that remove perfectly a little heavy metals of very small amount is increasing. Made ion exchange membrane and chelate forming group that use radiation graft polymerization method to remove Sb that is poisonous heavy metals among this. In this study, could know that wave and chelate forming group that compare adsorption special quality of Sb to use made ion exchange membrane and chelate forming group are effective to heavy metals removal.
