Particulate matter research is of great significance in solving atmospheric environment problems. The heterogeneous reaction of mixed gas on different mineral oxides and coal ash was studied based on a laboratory-built aerosol generating reactor. The product formed on particles was investigated by ion chromatography (IC). SO2 and NO2 could react on oxides to form secondary particles and the order of reactivity of mineral oxides under laboratory reaction conditions is: Al2O3>MgO>CaO>>SiO2, Fe2O3.... -
Influence of Tacrine on Catecholamine Secretion in the Perfused Rat Adrenal Gland
Seok-JeongJang, Won-HoYang, Dong-YoonLim 대한생리학회-대한약리학회 The Korean Journal of Physiology & Pharmacology 8 Pages
대한생리학회-대한약리학회 The Korean Journal of Physiology & Pharmacology 2002, Vol.6 No.4 6 207-214 (8 pages)
The present study was designed to clarify whether tacrine affects the release of catecholamines (CA) from the isolated perfused model of rat adrenal gland or not and to elucidate the mechanism of its action. Tacrine (3⁓105∼3⁓104 M) perfused into an adrenal vein for 60 min inhibited CA secretory responses evoked by ACh (5.32⁓103 M), DMPP (a selective neuronal nicotinic agonist, 104 M for 2 min) and McN-A-343 (a selective muscarinic M1-agonist,... -
초등학생의 체육수업이 BDNF, IGF-1 및 건강관련체력에 미치는 영향
한국웰니스학회 한국웰니스학회지 2013, 제 8권 4호 33 387-396 (10 pages)
순발력, 체지방율의 차이를 분석하기 위 해 대응표본 t검증(paired t-test)을 실시하였으며, 유의수준은 a=.05로 하였다. 연구결과를 보면 학교체육수업을 실시한 후 BDNF와 IGF-1의 변화는 유의한 증가를 보이며, 통계적으로 유의한 차이를 나타냈다(p<.05)(p<.05). 건강관련 체력의 경우 심폐지구력, 근력, 순발력, 체지방율에서 통계적으로 유의한 차이를 보였다(p<.05)(p<.05(p<.05)(p<.05). 따라서 뇌 발달시기인 초등학생에게 학교체육수 업은 혈중 BDNF, IGF-1 및 건강관련 체력의 향상에 긍정적인 효과를 주는 것으로 나타났다.
