Objectives:This study is conducted to investigate the effect of Attention Deficit and Hyperactivity Disorder(ADHD) symptoms on stress and suicide idea among 224 conscripts. Methods:Total number of subject is 224 conscripts. We evaluate symptoms of adult ADHD with Korean-Wender Utah rating scale(K-WURS) and Korean adult attention-deficit/hyperactivity disorder scale(K-AADHDS), stress with Brief Encounter Psychosocial Instrument-K(BEPSI-K), suicide idea with Scale for suicide ideation(SSI) after basic military training. Multivariate logistic analysis with backward stepwise selection is performed to evaluate risk factors of stress. Multiple linear regression analysis with stepwise selection is performed to evaluate association of suicide idea with adult ADHD symptoms. Results:Stress is significantly associated with K-WURS score, K-AADHDS score and SSI score(p<0.01, p<0.05, p<0.01). K-WURS score are significant risk factor of stress after basic military training(p<0.05, O.R : 1.034, 95% CI : 1.005-1.065). And K-WURS score influence suicide idea after basic military training(p<0.05, β : 0.031). Conclusion:The result suggests that K-WURS score might be a risk factor of stress and could affect suicide idea.

This paper aims to find out the unique Oriental Medical characteristics of the prescription Gami-Bojeongsan(加味普正散), which can only be found in 『Cheong-gang Euigam(晴崗醫鑑』 and the records of diagnosis by Kim Yeong Hoon. First, clues regarding Gami-Bojeongsan (加味普正散) in 『Cheong-gang Euigam(晴崗醫鑑)』 and the records of diagnosis by Kim Yeong Hoon have been collected, and then the origin of Gami-Bojeongsan(加味普正散) has been studied. Moreover, changes of prescriptions for common cold in East Asian Medicine have been looked into from historical perspective, and their connection to Gami-Bojeongsan(加味普正散) has also been researched. Lastly, connection of prescriptions for common cold found in royal records of the Chosun Dynasty to Gami-Bojeongsan(加味普正散) has been confirmed. The results are as follow: 1) Gami-Bojeongsan(加味普正散) is a most frequently used prescription in the records of diagnosis by Kim Yeong Hoon, and was used mostly in winter. It includes various modified versions. 2) Prescriptions that adopt Cyperi Rhizoma(香附子) as the sovereign medicinal, such as Gami-Bojeongsan(加味普正散), include Hyangsosan(香蘇散) of 『Hejijufang(和剂局方)』 and Hyang-gal-tang (香葛湯) of 『Dexiaofang(得效方)』 Hyang-gal-tang(香葛湯) is thought to have adopted Korean characteristics through Dong-Eui-Bo-Gam(東醫寶鑑) and 『Je-Jung-Shin-Pyeon』 and have continued its existence until it reached Gami-Bojeongsan(加味普正散) 3)These characteristics can be found in the royal records of the Chosun Dynasty, and also in Shin-Su- Tae-Eul-San(神授太乙散) of 『Euibang-Yuchui (醫方類聚)』.

트리플데카 착물류, bis-(η^5-cyclopentadienyl)-μ-(η^4-1,2,3,4-tetraalkylcyclobutadiene)dicobalt들은 Jonas시약과 2-hexyne 또는 3-hexyne을 실온에서 동량으로 반응시킬때, 50% 이상의 최대 수율이 얻어졌다. 한 종류의 트리플데카 착물인 bis-(η^5-cyclopentadienyl)-μ-(η^4-1,2,3,4-tetraalkylcyclobutadiene)dicobalt(13)는 실온에서 3-hexyne과 반응시키면, 착물 (η^5-cyclopentadienyl)cobalt-acyclopentadiene-μ-(η^4-2,4-cobaltacyclope-ntadiene)(η^5-cyclopentadienyl)cobalt(15)로 이성화되었다. 다른 한 종류의 트리플데카 착물, bis-(η^5-cyclopentadienyl)-μ-(η^4-1,3-dimethyl-2,4-dipropyl-cyclobutadiene)dicobalt(14)를 2-hexyne 과 반응시켰더니 1,3,5-tri-methyl-2,4,6-tripropyl benzene화합물이 생성되었다. The tripledecker complexes, bis-(η^5-cyclopentadienyl)-μ-(η^4-1,2,3,4-tetraalkylcyclobutadiene)dicobalt were produced by the reaction of Jonas reagent with 2-hexyne and 3-hexyne in the maxi-mum yield(above 50%) when they were reacted in eq-molar amounts at room temperature. A tripledecker complexes,bis-(η^2-cyclopentadienyl)-μ-(η^4-1,2,3,4-tetraalkylcyclobutadiene)dicobalt(13) was isomerized to (η^5-cyclopentadienyl)cobalt-acyclopentadiene-μ-(η^4-2,4-cobaltacyclope-ntadiene)(η^5-cyclopentadienyl)cobalt(15) on reacting with 3-hexyne at room temperature. Another tripledecker complex, bis-(η^5-cyclopentadienyl)-μ-(η^4-1,3-dimethyl-2,4-dipropyl-cyclobutadiene)dicobalt(14) was decomposed to give 1,3,5-trimethyl-2,4,6-trip-ropylbenzene through an intermediate complex by the reaction of 2-hexyne.

The present study was attempted to investigate the effects of total ginseng saponin (GTS), panaxadiol-type (PDS) and panaxatriol-type saponin (PTS) on contractile responses of vasoconstrictors in aortic smooth muscle stripes of normotensive (NR) and spontaneous hypertensive rats (SHR). Phenylephrine (an adrenergic α1-receptor agonist) and high potassium (a membrane depolarizing agent) caused greatly contractile responses in both NR and AHR aorta, respectively. Phenylephrine- and high potassium-induced contractile responses were greater in NA than those in SHR aortic smooth<br/> muscle stripes. In NR, the contractile responses of high potassium (5.6×10.2 M) were not affected in the presence of GTS (300 μg/ml), PDS (300 μg/ml), and PTS (300 μg/ml), respectively whereas phenylephrine (10.6 M)-induced contractile responses were markedly inhibited. In SHR, the contractile responses of high potassium (5.6×10.2 M) were not affected in the presence of GTS (300 μg/ml), PDS (300 μg/ml), and moderate doses of PTS (150-300 μg/ml), respectively but greatly blocked by high concentration of PTS (600 μg/ml). Phenylephrine (10.6 M)-induced contractile responses were<br/> inhibited in a dose dependent fashion (150-600 μg/ml) by the pretreatment with PTS while not altered in the presence of GTS (300 μg/ml) and PDS (300 μg/ml), respectively. Taken together, these experimental results suggest that ginseng saponins cause vascular relaxation through blockade of adrenergic α1-receptors and some unknown mechanisms, and that there is some difference in sensitivity of vascular smooth muscle between NR and SHR in responses to ginseng saponins. It seems that panaxatriol type of some ginseng saponins has the greatest potency in vascular relaxation.

TOP-1β is broadly localized to the nuclei of many cells at all developmental stages and concentrated in nucleoli in embryo gut and oogenic cells. However, TOP-1α is specifically localized to centrosomes, neuronal cells, excretory cells and chromosomes of germ cells in embryonic and larval stages. Reporter gene analysis also shows that <I>top-1</I> transcription is highly activated in several sensory neurons, speculating the possible role of TOP-1α in neuronal development. From RNA interference (RNAi) experiments, we demonstrated that <I>C. elegans</I> TOP-1 is required for chromosomal segregation, germline proliferation and gonadal migration, which are all correlated with the expression and activity of TOP-1. Therefore, our findings may provide an insight into a new role of TOP-1 in development of multicellular organisms.</P>

Purpose: This retrospective review was conducted to identify prognostic factors for two-stage reimplantation for infected total knee arthroplasty (TKA) and the rate of reinfection following revision TKA. Materials and Methods: Out of 88 patients diagnosed with post-TKA infection between 1998 and 2011, 76 underwent two-stage reimplantation and were reviewed in this study. The 76 patients were divided into two groups-hose who experienced reinfection and those who did not. Comorbidities, culture results, and inflammation indices were analyzed and compared between the two groups. Results: Of the 76 patients who underwent a two-stage reimplantation, 18 (23.7%) experienced reinfection. Patients with more than three comorbidities had significantly higher reinfection rates than those with less than three comorbidities (47.1% vs. 4.8%, p=0.032). The reinfection rate between the culture positive prosthetic joint infection group and the culture negative prosthetic joint infection group was not significantly different (p=0.056). Inflammation indices (erythrocyte sedimentation rate [ESR] and C-reactive protein [CRP]) showed a statistically significant difference between patients with reinfection and those without reinfection at 4 weeks after the first-stage surgery. Conclusions: Reimplantation must be carefully performed when the risk of reinfection is high, particularly in patients with more than three systemic or local comorbidities and higher inflammation indices (ESR and CRP) prior to revision TKA.
