This study was carried out to investigate the effect of phosphorus concentrations in fertilizer solution on growth and development of nutrient deficiency in leaf perilla (Perilla frutesens). The nutrient concentrations in above ground plant tissue, petiole sap and soil solution of root media were also determined. Phosphorus deficiency resulted in a slow growth, lustreless leaves, suffused purple tining in older leaves and falling prematurely. Elevation of P concentrations in fertilizer solution increased the crop growth at 75 days after transplanting. The fresh weight in 0, 0.5 and 4.0 mM treatments were 0.48 g, 9.28 g, and 25.5 g, respectively, and dry weights were 0.06 g, 1.46 g and 4.13 g, respectively. The P concentrations in above ground plant tissue and petiole sap in 4.0 mM treatment were 1.78% and $2.040mg{\cdot}kg^{-1}$, respectively, at 75 days after transplanting. The soil P concentration in 4.0 mM treatment was $1.26mg{\cdot}kg^{-1}$ when it was determined by the 1:2 (sample:water) method. These results indicated that P concentrations higher than 0.3% in above ground plant tissue, $900mg{\cdot}kg^{-1}$ in petiole sap, and $0.57mg{\cdot}kg^{-1}$ in soil solution should be maintained to ensure proper growth of leaf perilla (Perilla frutesens).

Short-chain acyl-CoA dehydrogenase (SCAD) deficiency is a rare mitochondrial fatty-acid oxidation disorder that is inherited as an autosomal recessive pattern. SCAD deficiency is caused by mutations in the ACADS gene (Acyl-CoA Dehydrogenase, Short-chain, OMIM #606885), which encodes SCAD, the mitochondrial enzyme that catalyzes the first reaction in the beta-oxidation of fatty acids four to six carbons in length. Here, we describe one Korean pediatric case of SCAD deficiency, which was diagnosed during newborn screening through tandem mass spectrometry. An increased concentration of butyrylcarnitine was detected on the newborn screening test, and the urine organic acid analysis showed increased urinary excretion of ethylmalonic acid. The patient has been asymptomatic and has shown normal growth and development by 8 months of age without any intervention during follow-up period.

Objective of this research was to investigate the effect of calcium concentrations in the fertilizer solution on growth and development of Ca deficiency in 'Maehyang' strawberry (Fragaria $\times$ ananassa Duch.). The margins of the youngest leaves were scorched and they developed a cupped shape as they were expanded in Ca deficient plants. The vein area of the youngest leaves became brown when the deficiency became severe. The quadratic responses were observed in dry weight production to elevated Ca concentrations in fertilizer solutions with the highest growth in 4.5 mM treatment. The regression equation was y=2.4026+1.0209x-$0.098x^2$ $(R^2=0.3546^{***})$. However, tissue Ca contents increased lineally as the Ca concentrations in fertilizer solutions were elevated (y=1.2108+0.1333x, $R^2=0.9189^{***}$). In changes of the fresh weight and Ca concentrations in petiole sap, fresh weight production showed quadratic responses to elevated Ca concentrations in fertilizer solution, but Ca concentration increased lineally. The equations in changes of fresh weight and Ca concentrations were y=9.273+4.882x-$0.4245x^2$ $(R^2=0.4935^{***})$ and y=52.311+3.2917x $(R^2=0.6918^{***})$, respectively. When the concentration of calcium at which plant growth was retarded by 10% is regarded as critical concentration level, the calcium contents based on dry weight of above ground plant tissue and in petiole sap should be in the range between 1.6 to 2.25% and 63 to $79mg{\cdot}kg^{-1}$, respectively.

많은 사람들이 에이즈의 첫 증상하면 붉은 반점을 흔하게 떠올리게 된다. 사실 이것은 에이즈 전구 증상이 아니고 사람면역결핍바이러스(HIV)에 감염되고 8-10년간의 무증상기를 거친 후에 인체의 면역기능이 바닥까지 망가졌을 때에 생기는 카포시 육종이라는 질병이다. HIV에 감염된 후에 면역기능이 파괴되면 본래 정상인에게 병을 일으키지 않는 미생물에 의해서 감염증이 생기고(이를 기회감염이라고 함)암도 발생하게 된다. 이와 같이 HIV 감염인에게 기회감염 혹은 암 등이 발생한 상태를 에이즈라고 한다. 어떤 사람들은 HIV에 감염된 후에 에이즈가 발병하기 전까지 아무런 증상을 느끼지 못하지만 일부는 에이즈 발병 전에 여러 가지 증상들(에이즈 전구 증상)을 겪게 된다. 오늘은 HIV에 감염된 후 에이즈가 발병하기 전에 발생할 수 있는 전구 증상들에 대해 알아보고자 한다.

This study was carried out to investigate the effect of potassium concentrations in fertigation solution on growth and development of nutrient deficiency symptoms of leaf perilla (Perilla frutesens). The nutrient concentrations in above ground plant tissue, petiole sap and soil solution of root media were also determined. Potassium deficiency symptoms developed in older leaves with marginal necrosis. The brown areas on the lower leaves enlarged rapidly and the margins became scorched. Elevation of K concentrations in the fertigation solution up to 8 mM increased the crop growth in leaf length, stem thickness, and fresh and dry matter production of above ground plant tissue. However, that decreased the chlorophyll contents. The 8.0 mM K treatment which showed the greatest growth had 5.01 g in dry weight and 2.76% in K content of above ground plant tissue, suggesting that maintaining K content higher than 1.7% is necessary for good growth of Perilla frutesens. The K concentrations in petiole sap and soil solution of 8.0 mM treatment were $12,289mg{\cdot}kg^{-1}\;and\;11.65mg{\cdot}L^{-1}$, respectively. These indicated that K fertilization to maintain higher than $8,700mg{\cdot}kg^{-1}$ in petiole sap and $4.5mg{\cdot}L^{-1}$ in soil solution are necessary to ensure good crop growth.

Objectives : The purpose of this study is to investigate the relationships between premonitory urge, tic severity, and comorbidities in children and adolescents with chronic tic disorders. Methods : In this study, scales for tic symptoms, premonitory urge, obsessive-compulsive symptoms, and ADHD symptoms were repeatedly measured twice in 26 children and adolescents aged 10 to 18 years with chronic tic disorders. Correlations between scales were confirmed through repeated measures correlation analysis, and causal relationships between scales were confirmed through regression analysis using a linear mixed model. Results : The degree of premonitory urges showed a significant positive correlation with the severity of tic symptoms, the severity of obsessive-compulsive symptoms, and the severity of ADHD symptoms. The ADHD symptoms showed a significant positive correlation with the severity of tic symptoms. These results were the same even in children and adolescents with tic disorders who were not diagnosed with obsessive-compulsive disorder. Additionally, premonitory urges were found to have a significant positive effect on the severity of tic symptoms. Conclusions : These results may be helpful in treating tic disorders and can be used in future tic disorder research considering developmental trajectory.

Object：The authors compared the attention-deficit hyperactivity(ADH) symptoms in childhood of adult male patients with bipolar disorder, schizophrenia and normal control subjects and attempted to find out whether attention-deficit hyperactivity disorder and bipolar disorder are related each other. Method：The authors compared ADH symptoms in childhood assessed with Wender Utah Rating Scale(WURS), selected 25 items of WURS(WURS-25), and Parent Rating Scale(PRS), and compared them between 26 bipolar, 29 schizophrenic, and 27 normal control subjects. Result：The subjects with bipolar disorder had significantly higher mean score of WURS compared with normal control group(One-way ANOVA, duncan test, WURS：DF=2, F=3.77 p=0.027), and the differences between the mean scores of WURS-25 and PRS of bipolar subjects and the other two groups were also highly significant(One-way ANOVA, Duncan test, WURS-25：DF=2, F=4.24 p=0.0178, PRS：DF=2, F=13.97 p<0.001). The mean scores of WURS, WURS-25, and PRS of schizophrenic subjects were higher than those of normal control group, though not significant. WURS and PRS were correlated for subjects with bipolar disorder(r=0.7495) and the normal control(r=0.5305), and there was no correlation for schizophrenic subjects. Conclusion：The ADH symptoms in childhood were much more evident for adult bipolar subjects than schizophrenic and normal control subjects. And these results are very suggestive that there might be some relationship between bipolar disorder and attention-deficit hyperactivity disorder and these two disorders might have a shared common pathophysiology which needs further study.

Objective of this research was to investigate the effect of nitrogen concentrations in the fertilizer solution on growth and development of nutrient deficiency in leaf perilla (Perilla frutesens). The nutrient concentrations in above-ground plant tissue, petiole sap and soil solution of root media were also determined. Nitrogen deficiency resulted in dwarfed growth, small leaves, and bright yellow color of older leaves. The leaves of deficient plants became uniform yellowing in color and finally necrosis occurred on the deficient leaves. Elevation of N concentrations in the fertigation solution from 0 to 20 mM increased the crop growth in leaf length and width as well as fresh and dry weights of above ground plant tissue. That also resulted in the increase of chlorophyll contents. However, light toxicity symptoms such as abnormal leaf surface appeared on crops grown in 20 mM N fertilization. The plant growth was commercially acceptable in the treatments of 10 and 15 mM N. The plants with acceptable growth had 0.9 to 1.25% in N contents of above-ground plant tissue, 800 to $3,300mg{\cdot}kg^{-1}$ in the $NO_3-N$ concentrations of petiole sap, and 28.7 to $47.3mg{\cdot}kg^{-1}$ in the $NO_3-N$ concentrations of soil solution (1:2 extract) at 75 days after transplanting.
