The acaricidal activity of the mixed plant extracts of Gleditsia japonica var. koraien, Camellia sinensis, Cinnamomum cassia, and Lantana camara, toward the tea red spider mite, Tetranychus kanzawai Kishida was evaluated in laboratory bioassays. Treatments with mixtures 1 and 3 were effective against the adult females of T. kanzawai and yielded 87.0 and 85.6% adulticidal activity at 7 days after treatment, respectively. Mixture 3 revealed 78.7% adulticidal activity. However, mixtures 4 and 5 had lower adulticidal activity than the other treatments. The adult females of T. kanzawai treated with mixtures 1 and 3 produced only 22.5-22.8% as many eggs as did the control females. The residue of the plant extracts tested had low adulticidal activity (16.3-27.2%). All of the plant extracts tested were ineffective against the eggs of T. kanzawai. Treatments with mixtures 1 and 3 were effective against the nymphs of T. kanzawai and led to emergence rates of 20.7 and 25.3%, respectively. These results suggest that mixtures 1 and 3 might be used for the control of T. kanzawai.

<B>Purpose: </B>PET-CT is often used to differentiate benign or malignant thyroid incidentalomas. In this retrospective study, we evaluated whether the <SUP>18</SUP>F-FDG uptake pattern and PET-CT findings improved accuracy over the standardized uptake value (SUV). <B>Methods:</B> <SUP>18</SUP>F-FDG PET-CT was performed on 2,178 subjects from August, 2004, to October, 2007, in Sung-ae Hospital. PET-CT was performed on 806 patients (37%) with suspected or known nonthyroidal cancer and 1,372 healthy subjects (63%) without a previous history of cancer. We investigated the clinical characteristics of patients, history, standardized uptake value (SUV), ultrasonography, and hormone levels in blood. Thyroidal cancer was confirmed by ultrasonography-guided fine needle aspiration and pathology after thyroid operation. <B>Results:</B> The prevalence of focal thyroid lesions on PET-CT was 8.8% (191/2178). Thyroid cancer confirmation was 7.9% (15/191). The maximum SUV of malignant thyroid lesions were significantly higher than that of benign lesions (7.00±3.08 vs. 4.49±1.84, P<0.001). <B>Conclusion:</B> PET-CT image interpretation that includes 18F-FDG uptake and SUV is better than PET-CT alone for differentiating benign and malignant lesions. Thyroid cancer risk increases as SUVmax levels increase. <B>(Ko</B><B></B><B>rean J Endocrine Surg 2008;8:38-42)</B>

Ultrastructural analysis of low-threshold mechanoreceptive vibrissa afferent boutons in the cat trigeminal caudal nucleus

Sang Kyoo Paik,Seung Ki Choi,Jong Wook Lee,Tae Heon Kim,Dong Kuk Ahn,Atsushi Yoshida,Yun Sook Kim,Yong Chul Bae 대한해부학회 2010 Anatomy & Cell Biology Vol.43 No.4

Ultrastructural parameters related to synaptic release and their correlation with synaptic connectivity were analyzed in the low-threshold mechanoreceptive vibrissa afferent boutons in laminae III and IV of the trigeminal caudal nucleus (Vc). Rapidly adapting vibrissa afferents were intra-axonally labeled, and quantitative ultrastructural analyses with serial sections were performed on the labeled boutons and their presynaptic endings (p-endings). The volume of the labeled boutons was widely distributed from small to large ones (0.8~12.3 μm3), whereas the p-endings were small and uniform in size. The volume of the labeled boutons was positively correlated with the ultrastructural parameters such as mitochondrial volume (correlation coefficient, r=0.96), active zone area (r=0.82) and apposed surface area (r=0.79). Vesicle density (r=-0.18) showed little correlation to the volume of labeled boutons, suggesting that the total vesicle number of a bouton is proportional to its volume. In addition, the bouton volume was positively correlated with the number of p-endings (r=0.52) and with the number of dendrites postsynaptic to the labeled bouton (r=0.83). These findings suggest that low-threshold mechanoreception conveyed through vibrissa afferents is processed in a bouton size-dependent manner in the Vc, which may contribute to the sensory-motor function of laminae III/IV in Vc.

Kim, Yong-Soon,Baek, Min-Won,Sung, Jae-Hyuck,Ryu, Hyun-Youl,Kim, Jin-Sik,Cho, Hyun-Sun,Choi, Byung-Gil,Song, Min-Sub,Song, Moon-Yong,Baik, Eun-Ju,Choi, Young-Kuk,Kim, Jong-Kyu,Yu, Il-Je,Song, Kyung-Se Korean Society of ToxicologyKorea Environmental Mu 2009 Toxicological Research Vol.26 No.3

The toxicity test of ammonium persulfate was conducted to ensure of its potential toxic effects according to the single-dose acute oral toxicity study (OECD Guideline 423) and 90-day repeated dose sub-chronic oral toxicity study guideline (OECD Guideline 408) for establishing national chemical management system, and matching in the Globally Harmonized Classification System (GHS) category. In acute oral toxicity study, pasty stool, perineal contamination and temporary body weight decrease were observed after dosing 1st and 2nd challenge (300 mg/kg body weight). All test animals were dead within 6 hours after dosing at 3rd challenge (2000 mg/kg body weight). Therefore, the GHS class of test substance is considered class 4. In sub-chronic toxicity study, body weight changes, food consumptions, hematological, biochemical and pathological examination did not show any noticeable and significant differences between the administered (5, 20, 80 mg/kg body weight) and control (vehicle only) group animals. Based on these results, the no observed adverse effect level (NOAEL) is considered above 80 mg/kg body weight.

Effects of Paclobutrazol and Prohexadione-Ca on Seed yield, and Content of Oils and Gibberellin in Flax Grown in a Greenhouse

Kim, Sang-Kuk,Han, Chae-Min,Shin, Jong-Hee,Kwon, Tae-Young The Korean Society of Crop Science 2018 한국작물학회지 Vol.63 No.3

We investigated the effect of paclobutrazol (PB) and prohexadione-Ca (PC) on seed yield, and the content of oils and endogenous gibberellin in flax grown in a greenhouse. Flax seedlings were cultivated in a greenhouse with average ambient temperature ranging from $35^{\circ}C$ to $38^{\circ}C$ during the growing period, and then PB and PC were applied on the leaves. The height of flax plants was reduced significantly by the foliar application of PB and PC. The highest ripening seed rate recorded was 94.5% with 2000 ppm PC; a 10.3% increase compared with that of the control. Both PB and PC markedly increased the fructification of flax seed. The application of two plant growth retardants resulted in higher seed production in flax seedlings grown in open field than in those grown in a greenhouse. The highest oil content was observed in flax treated with PC, whereas, the lowest oil content was observed in flax treated with PB. The oil content and ratio of unsaturated fatty acids were higher in flax seedlings grown in greenhouse than in those grown in open field. The level of two endogenous bioactive gibberellins ($GA_1$ and $GA_4$) in flax seeds decreased with the application of PB and PC. The flax plants treated with PB and PC presented higher secoisolariciresinol diglucoside content than that of the control. The optimal concentration of PC was found to be 2000 ppm. In conclusion, the foliar application of 2000 ppm PC might be useful in increasing oil content and seed production in flax plants.

Amniopatch treatment for preterm premature rupture of membranes before 23 weeks' gestation and factors associated with its success

Sung, J.H.,Kuk, J.Y.,Cha, H.H.,Choi, S.J.,Oh, S.y.,Roh, C.R.,Kim, J.H. Elsevier (Singapore) 2017 Taiwanese journal of obstetrics & gynecology Vol.56 No.5

Objective: The purpose of this study is to investigate the factors associated with successful amniopatch treatment in patients with iatrogenic preterm premature rupture of membranes (iPPROM) or spontaneous PPROM (sPPROM) before 23 weeks' gestation. Materials and methods: This cohort study included 28 women who received amniopatch treatment due to iPPROM or sPPROM at 15-23 weeks' gestation. Patients' clinical characteristics before performing the amniopatch, factors associated with the procedure, pregnancy and neonatal outcomes were compared between the iPPROM and sPPROM groups, and also between the successful and failed groups. Results: The amniopatch was successful in 6 of 28 patients (21.4%) with a success rate of 36.4% (4/11) and 11.8% (2/17) in the iPPROM group and sPPROM group (P = 0.174), respectively. The success group had a longer PPROM-to-delivery interval, fewer cases of clinical chorioamnionitis, larger birth weight, and lower neonatal intensive care unit admission rate than the failed group. The success rate of amniopatch procedure was proportional to maximal vertical pocket prior to procedure, which showed statistically significant association (adjusted odds ratio: 3.62, 95% confidence interval: 1.16-11.31, P = 0.027). Conclusion: The amniopatch treatment success rate was higher in the iPPROM group than the sPPROM group, but was not statistically significant. The neonatal outcome was more favorable when the amniopatch was successful. However, the only predictive factor associated with successful amniopatch was a larger amniotic fluid volume before the procedure.
