The button mushroom (Agaricus bisporus) is one of the most widely cultivated important edible mushroom species. In the breeding of new button mushroom, ‘Seolgang’ was developed by crossing two monokaryons ‘CM020913-27’ and ‘SSU423-31’. Because of the secondarily homothallism, only a small percentage of the basidia produce 3 or 4 spores, which are mostly haploid (n) and do not fruit. Single spore cultures derived from these types of spores produce a vegetative mycelium that also contain a variable number of genetically identical nuclei per cell called monokaryon. The lack of clamp connections between monokaryon and dikaryon required a series of mycelial culture and fruiting test. After crossing, hybrids were cultivated on a small scale and on a commercial scale at a farm. For this, the spawn was made by a commercial spawn producer and the spawned compost by a commercial compost producer. Mycelial growth of ‘Seolgang’ on CDA was better at 20℃ and 25℃ when it was compared with that of ‘505 Ho’. The mature cap shape of new strain ‘Seolgang’ is oblate spheroid and the immature cap shape is round to oblate spheroid. The cap diameter was 41.2 mm on average. In comparison with white strain ‘505 Ho’, the strain had a yield that was 9% higher. It produced fruiting bodies which had a higher weight on average per fruiting body and were 19% firmer with a good shelf life. Days of fruiting body were 3-4 days later than those of ‘505 Ho’. The physical characteristics such as elasticity, chewiness, adhesiveness were better than that of ‘505 Ho’. Genetic analysis of the new strain ‘Seolgang’ showed different profiles compared to ‘505 Ho’, CM02913-27, SSU413-31, when RAPD primers A02 and O04 were used.

The gas-assisted injection molding process is often perceived to be unpredictable, because of the extreme sensitivity of the gas. Since a slight change in design or process parameters can significantly change the resulting gas penetration, few designers and molders have the level of experience with the new gas-assisted injection molding process required for the development of new parts. This paper is concerned with the unified molding for a thick cosmetic chest by using gas-assisted injection molding. CAE analysis was carted out to design the part and the gas channel without inducing sink marks. And based on the part weight measurement, the processing parameters to control gas penetration percentage were chosen through the method of design of experiments. A thick cosmetic chest was successfully produced using the gas assist technology. The sink mark issue associated with the conventional injection molded parts was resolved. Weight savings and cycle-time reduction were also achieved.

Objectives : This naturalistic retrospective study investigated the effectiveness of ziprasidone measured by mean improve-ments of the Cltnical Global Impression (CGI-I). Secondary objectives included prescribing patterns, tolerability and safety. Methods : From May to July 2006, 98 psychiatric patients who have been taking ziprasidone for at least 2 weeks were selected. Their current clinical statuses were assessed by the interview and laboratory tests including electrocardiogram (ECG). Data on DSM-IV diagnoses, dosing, concomitant psychotropic medications, clinical changes, adverse effects, and laboratory findings were collected retrospectively. Results : Ziprasidone was mostly prescribed for a switch from another antipsychotics for the treatment of schizophrenia. Two main reasons for a switch were unsatisfactory efficacy and poor tolerance, especially weight gain, of the preceding anti-psychotic medication, Participants as a whole showed mean 2.7±1.0 of the CGI-Improvement. Significant weight reduction after switching to ziprasidone occurred, which was related to the clinical improvement. No significant increase of the QTc interval except one case was observed. Conclusion : The present study confirmed previous tolerability and safety data of ziprasidone as well as the results of its effectiveness.

정신분열병과 Neurotensin 수용체 유전자 다형성의 연합 연구

이유상,김형배,한진희,채영규,이정식,이혜순,주연호,김형섭,최인근,양병환 大韓神經精神醫學會 1999 신경정신의학 Vol.38 No.6

연구목적: Neurotensin(NT)은 NT수용체와 결합하여 그 효과를 나타내는 neuromodulator 혹은 neurotransmitter로서 대뇌에서 도파민의 분비를 조절하는데 중요한 역할을 한다. 근래의 연구에 의하면 NT와 그 수용체는 대뇌에서 항정신병 약물의 효과를 매개하는 것으로 생각되고 있으며 약물치료를 받지 않은 정신분열병 환자의 뇌척수액에서 NT의 양이 적으로 보고되고 있어 이들은 정신분열병과 깊은 관련을 가지고 있을 것으로 추정된다. 최근 NT수용체의 유전자의 3`인접영역에서 정보가치가 높은 4 염기반복 다형성이 발견되어 이를 유전 표지자로 하여 정신분열병과의 연합을 알아보았다. 방 법: 서로 혈연관계에 있지 않은 정신분열병 환자 120명(남자 91명, 여자 29명)과 정상 대조군 106명(남자 84명, 여자 22명)을 대상으로 하였다. PANSS를 사용하여 양성 및 음성을 알아보았다. 말초혈액에서 DNA를 분리한 후에 중합효소연쇄반응을 사용하여 3`인접영역에 있는 4 염기 반복 다형성을 증폭하였고 silver staining한 후에 유전자형을 관찰하였다. chi-square 검증과 Bonferroni`s correction을 사용하여 환자군과 정상 대조군간의 대립유전자 빈도의 차이를 알아보았다. 또한 양성 및 음성 환자군으로 나누어 차이를 알아보았다. 결 과: 총 23개의 대립유전자가 관찰되었으며, 399bp의 대립유전자(A10)의 빈도가 환자군보다 정상대조군에서 통계적으로 유의하게 높았다(χ²=16.49, df=1, p<0.001). 음성 정신분열병 환자군과 정상대조군 사이의 비교에서는 정상대조군의 A10의 빈도가 환자군보다 유의하게 높았다(χ²=21.33, df=1, p<0.001). 성별 비교에서 남자 정신분열병 환자군은 대조군에 비하여 A10의 분포가 유의하게 적었다. (χ²=13.71, df=1, p<0.001) 결 론: NT 수용체 유전자와 정신분열병사이에 음성연합이 관찰되었다. NT 수용체 유전자가 일부 정신분열병의 발병과정에서 확실하지는 않지만 어떤 종류의 보호기능을 할 수도 있다는 것을 암시한다. Objectives: Neurotensin(NT), of which functions are evoked by its interaction with neurotensin receptors(NTR), coexists with mesolimbic dopamine and regulates endogenous dopamine release. Recent studies have shown that NT with NTR exerts neuroleptic-like activity within the central nervous system and may play an important role in the pathogenesis and in the treatment of schizophrenia. We have examined the gentic association between schizophrenia and tetranucleotide repeat polymorphism in the 3-flanking region of the NTR gene to investigate the possible contribution of the NTR gene to the schizophrenia susceptibility. Methods: Among 23 alleles identified, the subjects were 120 patients(male 91, female 29)with schizophrenia and 106 normal healthy controls(male 84, female 22). They were unrelated native Korean. PANSS was used to determine positive or negative subgroup in the schizophrenic patients. Using polymerase chain reaction and polyacrylamide gel electrophoresis, tetranucleotide repeat polymorphism(CCTT and CTT) in the 3`-flanking region of NTR gene was observed. For a comparison of NTR gene`s allelic frequencies between patients with schizophrenia and normal healthy controls, chi-square test and Bonferroni`s correction was performed. Results: The frequency of A10 allele(base pair size=399)was significantly higher in normal healthy controls than schizophrenia(χ²=16.4902, df=1, p<.000). In the comparison between schizophrenic patients with negative symptoms and normal controls, the frequency of A10 allele was significantly higher in normal healthy control subjects than patients with schizophrenia(χ²=21.33, df=1, p<0.001). In the case of male, the frequency of A10 allele of schizophrenia was significantly higher than normal controls(χ²=13.71, df=1, p<0.001). Conclusions: NTR gene was negatively associated with schizophrenia. NTR gene`s tetranucleotide repeat polymorphism may provide some protective function against schizophrenia.

The purpose of this study was to examine through 24weeks whether dance education with 6-year old preschool-Kindergarten may increase positive self-concepts. The results of analysis of self-concept's change that the dance education served K kindergarten and not in the S kindergarten in Seoul were as follows. 1. There is a statistically significant relation of the generally satisfactory self-concepts between the two preschool-Kindergarten groups(P<0.05). It means that the development of satisfactory self-concepts are generally influenced by dance education programs. 2. There was no statistically significant relation of the same-aged children's self-concepts between the two preschool-Kindergarten groups (P>0.05). It means that the same-age children's self-concepts are not influenced effectively by dance education programs. 3. There was no statistically significant relation of the children's self-concepts about their teachers and kindergartens between the preschool-Kindergarten groups(P<0.05). It means that their teachers and kindergartens the children's self-concepts are not influenced effectively by dance education programs. 4. There was no statistically significant relation of the children's self-concepts about their classes between the two preschool-Kindergarten groups(P<0.05). It means that the children's self-concepts about their classes are not influenced by dance education programs. 5. There was no statistically significant relation of the children's self-concepts about their physical exercises between the two preschool-Kindergarten groups(P<0.05). It means that the children's self-concepts about their physical exercises are not influenced by dance education programs.
