H-S Lee, Y-S Lee, J-C Byun. The effects of EMG activity and blood fatigue makers on balance taping treatment by exercise type. Korean Journal of Sport Biomechanics, Vol. 14, No. 3, pp. 271-284, 2004. The purpose of this study was to analyse the EMG activity of selected muscles with balance taping treatment and blood fatigue makers which accumulated during exercise of progressive maximal intensity. Ten male college students who did not experience any cardiovascular and musculo-skeletal disease were participated in this study. Balance taping were applied to rectus femoris, vastus medialis, vastus lateralis, biceps femoris, semitendinous, semimembranous, and around knee joint. Isokinetic knee joint flexion/extension force, EMG activity, lactate and ammonia as blood fatigue makers during progressive maximal intensity exercise were measured for with/without applying balance taping. The results indicated that although flexion force of total work at 60˚/sec with taping was increased applied taping did not affect to the aerobic exercise ability parameters. Lactate level as blood fatigue makers during progressive maximal intensity exercise after taping was decreased but the ammonia level did not change with same treatment. In isokinetic knee joint test at the angular velocity of 60˚/sec, 180˚/sec, and 240˚//sec the taping treatment did not affect to any selected muscle EMG activities except maximal EMG of vastus lateralis at 240˚/sec.

This papaer was undertaken to do morphological analysis of wear particles for sliding members hydrauric rotary acuator. The lubricating wear test was performed under different experimental conditions using the wear test device and wear specimens of the pin on disk type was rubbed in parafinic base oil by three kinds of lubricating materials, varying applied load, sliding distance. The four shape parameters (50% volumetric diameter, aspect, roundness and reflectivity) are used for morphological analysis of wear particles. The results showed that the four shape parameters of wear particles depend on a kind of the lubricating materials. It was capable of presuming wear volume for three kinds of materials on driving time.

Naproxen(NPX) was administrered to a throrougbred mare in a single oral does. Plasma and urine samples were collected from 1 hour to 144 hours after administration, at varying intervals. The alkali hydrolysis was used for the seperation of glucuronide from the conjugated naproxen and its metabolite in urine. Naproxen and its metabolite desmethylnaproxen (DesNPX) were extracted at pH 4.0 with DCM/ETHETR/HEXAN(1/1/1, v/v/v) and quantitated by HPLC with diode-array-detector. The wavelength of ultraviolet was 235, 254 and 264 nm. The qulification of NPX and DesNPX was performed by gas-chromatograph-mass spectrometry using DB-1 column. Silylation (BSTFA including 1% TMCS) before the analysis of the extracted residue with GC/MSD was carried out for the detection of this drug and its metabolite. The characteristic ions (m/e) of trimethyl Silyated NPX and DesNPX were 73, 185, 302 and 73, 243, 360, respectively.

황산(98%) 처리시간과 온도가 풍선덩굴의 종자발아에 미치는 영향을 조사한 결과는 다음과 같다. 종자의 발아를 촉진시키는 효과적인 황산처리시간은 30분이었다. 발아율과 발아세는 30℃, 30분간의 황산처리구에서 각각 100% 34.17로 다른 처리구에 비해 가장 높았으며, 황산처리에 의한 발아율의 증가비는 다른 온도구에 비해 낮은 온도구에서 더 효과적 이었다. The seed germination were experimented according to period of sulfuric acid treatment at different temperature condition for Cardiospermum halicacabum L. The highest values of germination rate and velocity of seed were 100% and 34.10, respectively at 30℃ in 30 minutes' treatment with sulfuric acid. The effects of sulfuric acid treatment on seed germination was more increased in low temperatures' than in high.

박준식,정효순,권성우,이상숙 경북대학교 병원 2003 경북대학교병원의학연구소논문집 Vol.7 No.1

Background and Objectives : Extranodal non-Hodgkin's lymphoma(NHL) of the head and neck(H&N) accounts for 10-20% of all cases of NHL. Despite their frequency, the cause of these lymphomas is still poorly understood. Recently, the role of viral origin in NHLs, including Epstein-Barr virus(EBV), as the main cause of sinonasal lymphomas of T/NK cell phenotype and HTLV-1 as a cause of acute T-cell lymphoma/leukemia has been well documented. We investigated the clinicopathologic findings, immunophenotypic profile, and status of EBV and HTLV-1 DNA of patients with H&N lymphoma. Materials and Methods : Twenty-seven patients with NHL of H&N region were studied. There were 15 males and 12 females with the median age of 50 years. All patients were reclassified according to the Working formulation(WF) and REAL classification. EBV genome DNA and HTLV-1 RNA were surveyed by PCR assay using formalin-fixed and paraffin-embedded tissue blocks. Results : The tonsil was the most commonly involved site(44.4%) followed by nasal cavity(18.5%), nasopharynx(18.5%) and orbit(7.4%). Immunophenotyping revealed 19 cases of B cell lineage, 7 cases of T cell lineage and one case of null cell type. Most of B-cell lymphomas were diffuse large cell lymphomas(58%). Tonsillar lymphomas were all B-cell origin. Four of the five nasal cavity lymphomas and one nasopharyngeal lymphoma showed an angiocentric T/NK cell phenotype with strong association with EBV. EBV genome was detected in 15 of 26 H&N NHLs(57.7%). Seven of 19 B-cell lymphomas(36.8%) and all T/NK or null cell type lymphomas were positive for EBV DNA. However, there was no HTLV-1 positive cases found. Conclusions : It could be concluded that the high incidence of EBV of angiocentric T/NK-cell lymphomas of the nasal cavity may indicate a probable role of EBV in the development of these lymphomas.

Methods: A total of 100 patients with ASA physical status I-II scheduled for elective surgery were enrolled. After induction with propofol (1.5mg/kg), one hundred patients were randomly allocated to two groups (Group A: T1 height depression (T1%)≥90%, Group B:T1 height depression (T1%) < 90%). Three minutes after priming with rocuronium (0.06 mg/kg), Group A received 0.54 mg/kg rocuronium, Group B received sensitivity-adjusted dose of rocuronium, respectively. Intubation was performed when T1 height depression (T1%) = 0% (onset time). Neuromuscular function was assessed using Evoked Eletromyography (Datex Relaxo graph NMT. Datex. Helsinki. Finland). Results: Three minutes after priming (0.06 mg/kg), T1 height depression (T1%) in Group B (71.0 ± 8.8%) were significantly lower than Group A (98.4 ± 2.4%) (P < 0.05). The onset times in Group B (195 ± 29s) were significantly shorter (P < 0.05) than Group A (248 ± 34 s). Conclusions: Sensitivity-adjusted dose of rocuronium by priming decreased the onset times and total rocuronium dose.
