This is the case report of a 58-year-old man who developed acute severe hypoglycemia after a spinal block. He had a history of injecting insulin combined with 50% dextrose for hyperkalemia control. After the spinal block, he presented with hypo-glycemic symptoms and went into convulsions. Following injection of midazolam and 10 ml of 50% dextrose, his mental state returned to alert. We recommend careful monitoring of blood sugar level of chronic kidney disease patients who under-go neuraxial block.

본 연구의 목적은 필라테스 운동이 척추 측만증 환자의 요추 Cobb's angle에 어떠한 영향을 미치는지의 효과를 알아보는데 있다. 이 운동의 효과를 검증하기 위하여 필라테스 자세교정운동(PCE), 척추스트레칭운동(SSE), 근육강화운동(MSE)등을 시행하였다. 자세교정운동은 불균형한 근육에너지를 바로잡아주며 척추스트레칭 운동은 척추주변의 과 긴장된 근육을 이완시키고 근육강화운동은 주동근과 길항근의 균형을 잡아주어 척추 주변 근육의 탄력성과 유연성을 회복시켜주게 된다. 연구방법은 필라테스 적용 전과 적용 후의 X-ray 촬영에 의한 요추의 Cobb's angle을 측정하여 검증하였다. X-ray 촬영을 통한 Cobb's angle 실험 전 후의 결과는 필라테스 실시 후 약 5도 정도에서 통계적으로 유의하게 감소하였다(p=0.005). 따라서 필라테스 운동이 척추 측만증에 완화에 도움이 되는 것으로 나타났다.

Ankylosing spondylitis (AS) is an inflammatory joint disease affecting the axial skeleton, peripheral joints, entheses, and extra-articular site. Non-steroidal anti-inflammatory agents are the first line drugs for treatment of AS. Sulfasalazine is regarded as the second line drug and is usually used on AS patients with concomitant peripheral arthritis. Sulfasalazine has side effects, including liver toxicity, hematological abnormality, skin eruption, and other symptoms. However, eosinophilic pleural effusion is rare. Thus, we report on a patient with peripheral eosinophilia and eosinophilic pleural effusion after taking sulfasalazine for treatment of AS.

Benthic macroinvertebrates were seasonally sampled from upstream and downstream of the Gunwi Dam construction site from 2006 to 2012. Totally 148 and 165 species were collected at the upstream and downstream sampling sites, respectively. At the upstream area after dam construction, there was no significant change of the numbers of non-insect taxa, but at the downstream area, the non-insect taxon numbers were increased gradually. The individual ratio of Ephemeroptera and Diptera had higher value than the other taxa in both of up and downstream. The trichopteran individual ratios were increased in upstream sites, but decreased in downstream sites from 2010. Also, non-insects and coleopteran individual ratios were decreased in upstream, but increased in downstream after completion of dam construction. The annual range of fluctuation in community indices narrowed after construction. According to a functional feeding group analysis, the individual ratios of FC (Filtering Collector) were increased, and GC (Gathering Collector) and SC (Scraper) were decreased in upstream sites annually. In contrast, the annual individual ratios of FC were decreased, and GC and SC were increased in the downstream sites.

We have studied characteristics of community structure on the benthic macro-invertebrates at twelve selected sites in upstream, midstream and downstream of Paemsagol, Piagol, Chilseongol and Daeseonggol, major streams of Jirisan Mountain, for three years from April 2008 to September 2010. As a result, 2 phyla, 3 classes, 11 orders, 41 families, 119 species and 4,449 individuals of benthic macro-invertebrates have been collected and classified in this study. Among them EPT group (Ephemeroptera, Plecoptera, Trichoptera), commonly appearing taxa in clean stream ecosystem, was found most frequently. The highest species number of benthic macro-invertebrates were collected in 2008, the year with lower climatic influence including heavy rain. In almost all of survey sites 80% or over of EPT group were counted, and St. 1 scored highest rate of EPT group at 92.59%. Most dominant species was Ecdyonurus kibumensis at 12.83% of dominance index, and subdominant species was Goerodes KUb at 6.81% of dominance index. The investigation of the feeding function group indicated that gathering-collectors were dominant with 26 species and 1,334 individuals, while the number of filtering-collectors was lowest with 11 species and 230 individuals. This result represents that the feeding function group of Jirisan Mountain is mountainous stream-specific one. Both diversity index and richness index were lowest at the midstream of Chilseongol (St. 5), while the midstreams of Daeseonggol (St. 11) and Piagol (St. 8) were highest in diversity and richness indices respectively. The analyses of linear regression and correlation were performed in order to investigate and to predict the appearance aspect of EPT group by altitude. The results showed that the ratio of Plecopteran species number has increased by the elevation of the altitude at 0.05 significance level. Cluster analysis was also carried out for evaluating environmental similarities among survey sites. As a result, upper regions of Paemsagol (St. 1) and Piagol have clustered as most similar sites each other, while the midstream of Piagol (St. 8) has separated with lower similarity value than other sites in species composition.

Hydraulic habitat analysis of Benthic Macroinvertebrates was performed at Gapyeong stream. Among the kinds of the Benthic Macroinvertebrates, the most representative ones are the Ecdyonurus kibunensis from the clingers, Paraleptophlebia cocorata from the swimmers, Chironomidae spp from the burrowers, Psilotreta kisoensis iwata from the sprawlers. They showed different habitat types by the hydraulic conditions such as flow velocity, depth and particle size of riverbed materials. Habitat conditions of swimmers were determined mainly by the flow velocity rather than flow depth or riverbed materials. Burrowers prefer sand and silt, and inhabited at the riverbed. Sprawlers prefer cobble or boulder and inhabited for velocity of 0.05～0.15 m/s. Clingers prefer pebble or cobble and inhabited for velocity of 0.06～0.15 m/s. Although the habitats of each groups are different by the hydraulic properties, they were found to be different mainly by the water velocity.

This study was conducted to compare benthic macroinvertebrate communities of urban stream and nature stream in Daegu-si, Gyeongju-si, Gyeongsan-si, Andong-si, and Cheongsong-gun. The survey was carried out with 12 points in total six points for urban stream, six points for nature stream from Sept. 2011 to July 2012. In the urban stream were 33 species belonged to 24 families, 11 orders, 7 classes and 4 phyla while in the nature stream were 73 species belonged to 38 families, 12 orders, 5 classes and 4 phyla. In general, species diversity indices and species richness indices appeared low in urban stream but dominance indices was high. Functional feeding groups and Habitat Oriented Groups appeared comparatively simple in urban stream rather than nature stream. As a result of analysis of community stability, species included to areaⅠand area Ⅲ equally appeared in nature stream while species included to area Ⅰ mostly appeared in urban stream. An analysis of the correlation between the population density and the number of species, the population number and biological indicators such as DI, H', RI, and ESB revealed that there was a significant correlativity with the diversity index and a very high correlativity with the number of species, abundance index and the ESB. On the other hand, the population number and the dominance index did not reveal any correlativity. For indicator species, Hydroptila KUa, Physa acuta appeared in urban stream while Paraleptophlebia chocolata, Epeorus pellucidus appeared in nature stream.

본 연구의 목적은 특발성 척추 측만증 환자를 대상으로 요가 운동 요법을 통하여 척추 측만각도 즉 요추 Cobb's angle의 정도를 분석하여 요가 운동 프로그램이 특발성 척추 측만연구에 어떠한 영향을 미치는지의 효과를 알아보는데 있다. 본 연구의 요가 운동 프로그램은 척추주변의 근육들의 지나친 긴장을 풀고 이완된 근육은 수축운동을통하여 유연성과 탄력을 회복하여 운동 시 주동근과 길항근의 균형을 맞추고 협력근과의 조화로운 상태가 척추측만에 도움될 것으로 판단하여 골반운동과 척추 비틀기 운동을 중심으로 실시하였다. 실험대상은 광주광역시 소재C병원에서 특발성 척추 측만증 진단을 받은 여자 중학생을 대상으로 하여, 요가 운동 프로그램으로 주5일, 1일 60분, 12주간 실시하여 요가 운동프로그램이 특발성 척추 측만증 변화에 미치는 영향을 알아보고자 실시하였다. 실험 전, 후 방사선을 통하여 요추의 Cobb's angle을 측정하여 효과를 검증하였다. 첫째, 요가 및 척추 전문가와함께 연구하여 동작을 추축하였다. 둘째, 개발된 척추측만증에 대한 요가 운동 프로그램을 특발성 척추 측만증을갖고 있는 여중생에게 12주간 실시하였다. 셋째, 특발성 척추 측만증에 대한 요가 운동 프로그램에 대한 타당성과효과를 검증하였다. 그 결과 운동 전보다 5도가 통계적으로 유의하게 감소하여 (p=0.006)특발성 척추 측만증이 개선되었다.

Behcet’s disease (BD) is characterized by oral or orogenital ulcers and various systemic symptoms. Ankylosing spondylitis (AS), a prototype of the seronegative spondiloarthropathy(SNSpA) group, is a chronic inflammatory disease of the axial skeleton primarily involving the sacroiliac joint and vertebrae. Coexistence of BD and AS has rarely been reported. We report on a patient with concomitant AS and BD who was treated successfully with etanercept. Several case reports suporting the effectiveness of other medications such as NSAIDs in patients with coexisting AS and BD have been reported in the literature. However, we found no report regarding the use of anti TNF-α agent for treatment of these patients except for one case of adalimumab. To be best of our knowledge, this is the first case of a patient with concomitant AS and BD treated with etanercept.

Chronic effects such as reproduction and population dynamics with elevated CO2 concentration were evaluated using two representative marine benthic species, copepod (Tisbe sp.) and amphipod (Monocorophium acherusicum) adopting long-term exposure. Juvenile copepod and amphipod individuals were cultivated in the seawater equilibrated with control air (0.395 mmol CO2/air mol) and high CO2 air having 0.998, to 3.03, 10.3, and 30.1 mmol CO2/air mol during 20 and 46 days, respectively. After the exposure period, the number of benthic invertebrate was counted with separate larval and juvenile stage such as naupliar, copepodid and adult for copepod, or neonate and adult for amphipod, respectively. The individual number of both test species at each life-stage was significantly decreased in seawater with 10.3 mmol CO2/air mol or higher. Recently, the technology of marine CO2 sequestration has been developed for the reduction of CO2 emission, which may cause climate change. However, under various scenarios of CO2 leaks during the injection process or sequestrated CO2 in marine geological structure, the potential risk to organism including various invertebrates can be expected to exposure. So the results of this study suggested that the detailed consideration on the adverse effect with marine ecosystem can be prerequisite for the marine CO2 sequestration projects.

This study was conducted for determining the influence of artificial structures on benthic macroinvertebrate communities in stream. Sampling was taken at upper(pool), down(riffle) and control(riffle) from two check dams, two weirs, one agricultural reservoir, and one multipurpose dam in northern part of Gyeongsangbuk-do. The benthic macroinvertebrate communities of these structures were surveyed during 2009 to 2011. The simple habitat of benthic macroinvertebrates occurred at the upper sites due to pooling effects from artificial structures. Specifically, Check dam1, Jusanji, Imha dam showed very low biological attribute values compared to the down and control sites, which have greater difference in substrate characteristics. However, in the upper sites of Check dam2, Weir1 and Weir2, the difference of values of biological attributes was relatively smaller. Also, proportion of functional feeding groups and functional habit groups were relatively simpler at upper stream and the degree of community differences was greater between upper and down, control sites. Spearman’s correlation between biological attributes and substrate characteristics, water quality parameters had significant correlations; particularly, the substrate characteristics were more significantly related. In conclusion, the pool caused by artificial structures had negative effects on benthic macroinvertebrate communities thus leading to simplified stream habitats at upper stream ecosystems.

Spinal epidural lipomatosis (SEL) is a rare condition of adipose tissue accumulation in the epidural space. A total of 2,309 subjects from March 2011 to April 2012 were studied. We found different morphologic “variants” of dural sac compression in grade III. The trifid type, resembling the letter “Y", was the most common form. The round type and the localized mass in lateral recess were seen in other cases. Surgical decompression was performed regardless of morphologic variants in SEL grade III with neurologic symptoms. All patients recovered from neurologic symptoms. In subjects who received adequate conservative treatment, decompressive surgery could be helpful in treatment of SEL grade III with neurologic symptoms.

The midge samples were undertaken at three streams, representing different surrounding environments, to investigate the contaminant exposure of midge. The content of heavy metals in midge collected in Singil stream were generally higher as a result of input to the industrial effluents with respect to other streams. Adsorption experiments were done to evaluate the possibility of removing contaminants from water with midge. Diazinon and heavy metals were contaminant target compounds in this study. The removal rate of diazinon in water by midge was 60-75%. In the case of Cu, the removal rate was reached around 90% at the lower initial concentration of 1.87 and 0.81 ppm rather than 4.25 ppm. The reduction of concentration of Cr and Cd according to the lapse of time was similar to the Cu, but their removal rates were shown 50% and 60-74%, respectively. The removal rate of Zn by midge represented relatively high level within the experimental condition. No change in concentration of Cr and As with time were occurred at all experimental conditions. It accounts for the fact that the reduction of Cr and As could not be achieved through the adsorption process, using midge.

양식 종묘생산 현장에서 발생하는 기형 중에는 척추 기형 발생빈도가 매우 높은 것으로 알려져있으나, 초기 발생과정 동안에는 육안적 관찰이 매우 어려울 뿐만 아니라, 사육환경의 여러 가지 요인에 따라 기형의 양상도 달라지므로 (Vågsholm and Djupvik, 1998) 정확한 발생원인 분석이 어려운 실정이다. 기형의 형태적 검사법은 주로 morphometry을 이용하여 외부형태의 수리적 해석을 접목한 분석기법 (Bookstein, 1997; Kawamura and Hosoya, 1997), X-ray 촬영에 의한 골영상 분석기법 또는 bone & cartilage double stain 기법 (Park and Kim, 1984) 그리고 추체의 구조적 특징을 분석하는 골형태학적 분석 기법 (Witten et al., 2009) 등이 주로 이용되고 있다. 이 중 골형태학적 분석기법은 직접적으로 뼈를 관찰하기 때문에 기형 증상 판별에 있어 가장 높은 신뢰성을 보이는 것으로 알려져 있다. 따라서 본 연구에서는 우리나라 대표적 양식대상종인 돌돔 성어 (1년생 이상, n=40)와 미성어 (1년생 이하, n=28)를 대상으로 X-ray에 의한 분석, 정상어와 척추기형어 간의 외부형태 비교분석을 통하여 기형어 판별방법으로서의 이용가능성을 알아보고, 골형태학적 분석 기법을 통하여 추체변형 타입을 정확히 판별함과 동시에 돌돔의 기형 판별에 대한 기준을 제시하고자 하였다. X-ray 사진촬영에 의한 분석 결과, 돌돔 성어 및 미성어에서 조사된 척추기형 중 전만증 발생비율은 각각 67.5%, 21.4%로 조사되었으며, 단구증 (vertebral compression)의 경우 각각 32.5%, 14.3%로 조사되어 다른 척추기형 증상에 비해 높게 나타났다. X-ray 판독에 의해 분류된 정상어와 척추기형어간의 외부형태 비교에서는 성어의 경우, (체장-두장)/두장값과 체고/두장값이 유의적 차이를 보였지만, 미성어의 경우 두 그룹 간에 차이가 없는 것으로 조사되었다. 이 같은 결과는 기형어 내에서도 개체간의 척추변이의 정도 (服部, 2004)나 가계 간에도 외부형질이 변화한다는 보고(谷口 등, 1995)에 비추어 볼 때 기형판별의 기준점으로 제시하기는 어려울 것으로 생각된다. 양식산 돌돔의 성어 및 미성어에서 골형태학적 분석 기법으로 조사한 결과, 추체의 경우 압착 및 유합, 비대칭, 탈구 그리고 추체 사이의 비정상적 간격이 조사되었고, 전체적인 척추의 형태는 전만증, 후만증 그리고 복합적인 척추 기형 증상을 보였다. 본 연구에서는 돌돔을 대상으로 추체 기형판별을 위한 기초조사로서 상업적 양식장 한곳만을 대상으로 조사하였다. 그러나 추체의 변형을 유발하는 여러 가지 직․간접적인 사육환경 요인들이 보고되고 있고 (Kvellestad et al., 2000; Madsen et al., 2001; Hattori et al, 2004; Aunsmo et al., 2008), 추체변형의 종류는 어종별로 차이를 보이기 때문에 (Favaloro and Mazzola, 2000; Boglione et al., 2001; Lewis et al., 2004; Witten et al, 2009), 각 지역에 위치한 양식장을 대상으로 장기적이고 체계적인 조사가 필요할 것으로 생각된다.

This research was carried out to investigate invertebrate fauna with organic and conventional pear orchards, which used four collected methods; soil sampling for soil microorganism, pitfall, malaise, and black light trap for over ground species. Collected species were 37 species, 1,184 individuals in organic and 28 species, 501 individuals by soil sampling in conventional pear fields. Those were 38 species, 646 individuals and 29 species, 440 individuals by pitfall trap, 55 species 650 individuals and 47 species, 508 individuals by malaise trap, and 23 species, 201 individuals and 9 species, 42 individuals by black light trap. Collembola was collected 389 individuals in organic which was 5 times than in conventional in soil sampling. In pitfall trap, that was 183 individuals which was 3 times. The diversity indices of organic pear orchards were 1.956 in May, 2.638 in August and those of conventional was 1.426 in May, 2.011 in August in soil sampling. In pitfall trap, the dominant species were spiders, collembollan, and coleopteran. Among Coleoptera, indicator insects for the evaluation of agricultural environment suggested were Eusilpha jakowelewi as organic pear orchard and Anisodactykus punctatipennis and Pheropsophus jessoensis as conventional. Malaise trap was collected dominant species as Diptera and Hymenoptera of Braconidae and Ichneumonidae. The diversity indices of organic pear orchards were 2.952, 3.120, and 2.010 in pitfall, malaise and black light trap in over ground invertebrate sampling. The highest diversity was in malaise trap. The higher diversity indices, the lower dominance indices.

The studies on community structure of benthic macroinvertebrates and environmental survey in selected four sites were performed on wetland Upo from 2008 to 2009. The lowest water temperature was measured at Upo and Mokpo showing 7℃ in February of 2008 and 2009 respectively. The highest water temperature was measured at Upo showing 32℃ in August of 2009. The lowest pH was measured at Topyeong with 5.3 in August of 2009, and the highest pH was measured at Mokpo with 10.1 in August of 2008. Generally the levels pH of 2008 were higher than those of 2009. The range of electric conductivity to the sites was big. Overall, the higher electric conductivity was seen at Sajipo and the lower one was seen at Mokpo. The level of Dissolved oxygen was lowest at Upo with 5.53㎎/ℓ in August 2008, and it was highest at Upo with 14.76㎎/ℓ in February of 2008. The investigation was performed with both quantitative and qualitative collecting methods from four surveying sites, Upo, Mokpo, Sajipo and Topyeong. Through the eight times of seasonal survey, 6 classes, 17 orders, 59 families, 131 species and 5460 individuals of benthic macroinvertebrates were collected. 6 classes, 17 orders, 53 families 106 species and 2439 individuals were identified in 2008, and 6 classes, 16 orders, 44 families, 93 species and 3021 individuals were collected in 2009. The number of species was decreased in 2009 comparing that of 2008, however, the number of individuals were increased in 2009. The dominant species and the subdominant species was Plea (Paraplea) indistinguenda and Diplonychus esakii with 20.16% and 11.90% of dominant indices respectively. From the community analysis, both the species diversity index and the species richness index were highest in Topyeong showing 4.743 and 9.054 respectively. The similarity evaluation to the investigation sites with the species in there showed very high similarity among Upo, Mokpo and Sajipo showing 5 or lower levels of distance cluster combine.

전이성 척추암 환자를 대상으로 1.5 T MR 기기에서 조영제 주입 전⦁후 확산강조영상에서 전이가 된 요추의 신호 대 잡음비, 대조도대 잡음비, 현성 확산 계수가 어떤 변화를 나타내는지 알아보고자 하였다. 영상의 정량적 분석에서는 전이성 척추암 그룹의 경우 조영제 주입 전 확산강조영상에서 전이성 척추암이 있는 부 위와 척추암이 있는 부위의 위, 아래 척추등 세 부위의 신호대 잡음비는 척추암이 있는 부위에서 낮게 나타났으며 조 영제 주입 후 확산강조영상에서는 조영제 주입 전보다 세 부위 모두 신호대 잡음비가 상대적으로 증가하였으며 척추암 이 있는 부위의 위, 아래 척추등 두 부위 에서는 대조도대 잡음비가 상대적으로 증가했다. ADC map영상에서는 조영제 주입 전에서 신호대 잡음비는 척추암이 있는 부위에서 높게 나타났으며 조영제 주입 후에서는 조영제 주입 전보다 전 이성 척추암이 있는 부위와 척추암이 있는 부위의 위, 아래 척추등 세 부위 모두 신호대 잡음비가 상대적으로 감소했 다.

ADC map영상에서의 현성 확산 계수 는 세 부위 모두 현성 확산 계수가 상대적으로 감소했다. 영상의 정성적 분석에서 조영제 주입 후 확산강조영상에서 전이성 척추암이 있는 부위의 신호강도가 증가하였고 ADC map영상에서는 신호강도가 감소하였다. 조영제 주입 후 확산강조영상에서 전이성 척추암이 있는 부위와 척추암이 있는 부위의 위, 아래 척추 등 세 부위 모두 신호대 잡음비와 대조도대 잡음비가 증가하고 현성확산계수가 감소하는 결과를 얻었고 조영제 주입 후 확산강조영 상이 여러 가지 척추질환으로의 적용에 도움을 줄 것이라 사료된다.

골다공성 폐경 후 여성에서 단일 에너지를 이용한 정량적 전산화 단층촬영술로 골무기질 함량을 측정하여 건강한 여성과 비교분석하였다.1군은 건강한 폐경전 여성, 2군은 폐경후 건강한 여성, 3군은 골다공증성 폐경후 여성으로 나 눈 환자들에게 QCT를 이용하여 측정된 골밀도가 각 군간에 차이가 있는지 알아보고 각 군내 혹은 다른 군간에 척추 부위에 따른 영향이 있는지를 부위별로 비교분석하였고, 골무기질 함량의 측정은 타원형의 region of interest를 이용 하여 T12-L4에서 척추의 해면질 부위에서 측정하였다. 연령이 증가함에 따라 골밀도는 감소하였고 건강한 군과 비교하여 골다공증 환자군에서 유의하게 낮은 골밀도를 관찰 할 수 있었다. 건강한 폐경전 여성군을 제외한 모든군에서 T12에서L4로 갈수록 골밀도가 감소하였다. 통계학적 으로 모든 척추체에서 골밀도로 1, 2, 3군간 서로를 구분할 수 있으나 2군과 3군은 골밀도로는 서로간의 구분할 수 없 는 것으로 분석되었다.

The distribution of benthic macroinvertebrates in Daecheon stream, an urban stream of Busan, was investigated to analyze the community structure of benthic macroinvertebrates. The collection was peformed monthly at five(A~E) sites divided into three parts, upper, middle and lower, of stream from January to November, 2004. In physicochemical analysis of environmental factors, water quality parameters such as BOD, COD, conductivity and ABS were relatively increased in sites B and C. Whereas sites A, D and E showed little variations with good water quality parameters. However, water quality parameters in all surveyed sites showed gradual decrease with time toward improvement of water quality. A total of 8,226 individuals including 4 phyla, 6 classes, 9 orders, 302 families and 44 species were identified from five sites. The most dominant group was insect(class Insecta), and order Ephemeroptera and Diptera among insect was the largest member in species(30.6%) and individuals(75.0%) of benthic macroinvertebrates, respectively. The primary dominant species were Gammarus sp. and Ephemera strigata in site A, whereas Chironomus sp. and Brenchiura sowerbyi were dominated commonly in the other sites. In community analysis of benthic macroinvertebrates of Daecheon stream diversity index showed relatively low values, whereas dominance index was significantly high. Diversity index was the highest in site A, whereas the dominance index was the highest in site B. However, diversity index showed gradual increase with time showing adverse mode in dominance index. From these results, it can be suggested that long-term ecological monitoring of benthic macroinvertebrate fauna is needed for sustainable management of Daecheon stream.

The study on community structure of benthic macroinvertebrates from wetland Woopo was conducted for the long-term ecological monitoring. The wetland Woopo is located in Changnyeong-Gun, Gyeongsangnam - Do of Korea. In 2006, we investigated the seasonal variation of benthic macroinvertebrates with quantitative and qualitative collecting methods. The collection was performed monthly at four surveying region, Woopo, Sajipo, Mokpo and Topyong stream. In this study, 6 classes, 16 orders, 48 families, 95 species were identified on group of benthic macroinvertebrates. The species diversity index and the species richness index were the highest in Topyung region and it was 3.222 and 10.216 respectively. The two species, Cercion calamorum and Cloeon dipterum were quantitatively collected for 9 months. The changes of body lengths of 50 individuals were recorded and the advanced growth on the two species was expected from present study.
