Background & Object : Dyspepsia for which no organic causes are disclosed is referred to as functional dyspepsia. Functional dyspepsia is here studied in connection with a biopsychosocial model. From the aspect of individual response to external environment, in connection with stress response, functional dyspepsia is studied by both the psychology department and the internal medicine departments. The disease is taken as approachable from the aspect of internal injury due to seven emotions and stress as differentiated by Oriental medicine. Materials and Methods : Targeted at 223 patients underwent medical checks and endoscopy at Kangnam Korean Hospital, Kyunghee University. They agreed to join this clinical experiment. Stress response inventory, GARS (global assessment of recent stress scale), GSRS (gastrointestinal symptom rating scale), diagnostic scores for Ki-depression, and Spleen Disease Differentiation of Syndromes were all measured and evaluated. The test group was comprised of functional dyspepsia patients. The control group was comprised of nonsymptomatic chronic gastritis patients who were found to suffer from chronical gastritis in endoscopy and thus could be diagnosed with functional dyspepsia if symptoms would arise, but did not complain of subjective symptoms. Results showed these corelations: Functional dyspepsia patients were found to have more serious Ki-depression compared to nonsymptomatic chronic gastritis patients. The more serious Ki-depression the more serious the dyspepsia symptoms. The higher the stress response inventory the more serious the dyspepsia. Deficiency of spleen Eum, and Deficiency and Sinking of spleen Gi were found to coincide with serious Ki-depression.

Effects of pyridoxine on a high‐fat diet‐induced reduction of cell proliferation and neuroblast differentiation depend on cyclic adenosine monophosphate response element binding protein in the mouse dentate gyrus

Yoo, Dae Young,Kim, Woosuk,Yoo, Ki‐,Yeon,Nam, Sung Min,Chung, Jin Young,Yoon, Yeo Sung,Won, Moo‐,Ho,Hwang, In Koo Wiley Subscription Services, Inc., A Wiley Company 2012 JOURNAL OF NEUROSCIENCE RESEARCH - Vol.90 No.8

<P><B>Abstract</B></P><P>In this study, we challenged pyridoxine to mice fed a high‐fat diet (HFD) and investigated the effects of pyridoxine on HFD‐induced phenotypes such as blood glucose, reduction of cell proliferation and neuroblast differentiation in the dentate gyrus using Ki67 and doublecortin (DCX), respectively. Mice were fed a commercially available low‐fat diet (LFD) as control diet or HFD (60% fat) for 8 weeks. After 5 weeks of LFD or HFD treatment, 350 mg/kg pyridoxine was administered for 3 weeks. The administration of pyridoxine significantly decreased body weight in the HFD‐treated group. In addition, there were no significant differences in hepatic histology and pancreatic insulin‐immunoreactive (‐ir) and glucagon‐ir cells of the HFD‐treated group after pyridoxine treatment. In the HFD‐fed group, Ki67‐positive nuclei and DCX‐ir neuroblasts were significantly decreased in the dentate gyrus compared with those in the LFD‐fed mice. However, the administration of pyridoxine significantly increased Ki67‐positive nuclei and DCX‐ir neuroblasts in the dentate gyrus in both LFD‐ and HFD‐fed mice. In addition, the administration of pyridoxine significantly increased the protein levels of glutamic acid decarboxylase 67 (GAD67) and brain‐derived neurotrophic factor (BDNF) and the immunoreactivity of phosphorylated cyclic AMP response element binding protein (pCREB) compared with the vehicle‐treated LFD‐ and HFD‐fed mice. In contrast, the administration of pyridoxine significantly decreased HFD‐induced malondialdehyde (MDA) levels in the hippocampus. These results showed that pyridoxine supplement reduced the HFD‐induced reduction of cell proliferation and neuroblast differentiation in the dentate gyrus via controlling the levels of GAD67, pCREB, BDNF, and MDA. © 2012 Wiley Periodicals, Inc.</P>

KIM, Il Yong,HWANG, In Koo,CHOI, Ji Won,YOO, Ki-Yeon,KIM, Yo Na,YI, Sun Shin,WON, Moo-Ho,LEE, In Se,YOON, Yeo Sung,SEONG, Je Kyung Japanese Society of Veterinary Science 2009 The Journal of veterinary medical science Vol.71 No.6

<P>In this study, we observed and compared the effects of a high cholesterol diet (HCD) on cell proliferation and differentiation in the subgranular zone of the dentate gyrus of C57BL/6N (B6, susceptible strain) and C3H/HeN (C3H, resistant strain) mice. Ki67 (a marker for cell proliferation) positive cells) were significantly decreased in HCD-fed B6 mice compared to those in B6 (49.7%) and C3H mice fed a low cholesterol diet (LCD). In addition, doublecortin (DCX, a marker for cell differentiation or neuroblasts)-immunoreactive cells in HCD-fed B6 mice were significantly decreased compared to those in LCD-fed B6 and C3H mice. These results suggest that B6 strains are sensitive to HCD, which impairs cell proliferation and differentiation.</P>

연구목적 : 본 시험의 목적은 임상시험 시작전에 연구자들을 대상으로 PANSS Workshop을 통하여 PANSS, ESRS에 대한 국내에서의 표준화 작업을 구축하고 새로운 정신병 치료제인 리스페리돈의 효과와 안정성을 재확인하여 리스페리돈 사용에 대한 적정화를 이루는데 있다. 연구방법 : 1996년 4월부터 1996년 9월까지 국내 39개 대학병원 정신과에 입원중인 혹은 증상이 악화되어 입원하는 정신분열병 환자 377명을 대상으로 다시설 개방 연구를 시행하였다. 1주일간의 약물 배설기간을 가진후, 리스페리돈을 8주간 투여하였고, 기준점, 1주, 2주, 4주, 그리고 8주후에 평가되었다. 용량은 제1일에는 리스페리돈 1mg씩 1일 2회, 제2일에는 2mg씩 1일 2회, 제3∼7일에는 3mg씩 1일 2회 투여하였다. 이후 환자의 임상상태에 따라 임의로 증량할 수 있으며, 최대 일일 16mg을 초과하지 않도록 하였다. 추체외로 증상을 조절하기 위한 투약을 허용하였다. 임상증상 및 부작용의 평가는 PANSS(Positive and Negative Syndrome Scale), CGI(Clinical Global Impression) 그리고 ESRS(Extrapyramidal Symptom Rating Scale)을 사용하였다. 연구결과 : 377명중 343명(91%)이 8주간의 연구를 완결하였다. 치료 종결시점인 8주후 PANSS 총점수가 20% 이상 호전된 경우를 약물 반응군으로 정의할때, 약물반응군은 81.3%였다. 리스페리돈에 반응하는 예측인자로는 발병연령, 이전의 입원 횟수, 유병기간이 관련 있었다. 리스페리돈은 1주후부터 PANSS양성, 음성, 및 일반정신병리 점수상에 유의한 호전을 보여 효과가 빨랐다. CGI의 경우도 기준점에 비해 1주후부터 유의한 감소를 나타내었다. ESRS의 경우, 파킨슨 평가점수는 기준점과 비교해 투여 1주, 2주, 4주후 유의하게 증가되었다가 8주후 기준점과 차이가 없었다. Dystonia 평가점수는 1주후만 유의한 증가를 보였으며, dyskinesia 평가점수는 유의한 차이가 없었다. 혈압, 맥박수의 생명징후 및 일반 혈액학 검사, 생화학적 검사, 심전도 검사에서 유의한 변화는 없었다. 결 론 : 이상의 다시설 개방 임상 연구를 통해 리스페리돈은 정신분열병 환자에서 양성증상뿐만 아니라 음성증상 및 전반적인 증상에도 효과적인 것으로 사료된다. 보다 명확한 평가를 위해서는 다른 항정신병약물과의 이중맹검 연구가 필요할 것으로 생각되며, 또한 장기적 치료에 대한 평가도 함께 이루어져야 하겠다. Objective : The purpose of this study was to investigate the efficacy and safety of risperidone in the treatment of Korean schizophrenic patients. Method : This multicenter open study included 377 schizophrenic patients drawn from 39 university hospitals. After a wash-out period of 1 week, the schizophrenic patients were treated with risperidone for 8 weeks and evaluated at 5 points ; at baseline, and 1, 2, 4 and 8 weeks of treatment. The dose was increased from 2mg/day(1mg twice daily) to 6mg/day(3mg twice daily) during the first week and adjusted to a maximum of 16mg/day over the next 7 weeks according to the patient's clinical response. Medication to control extrapyramidal symptoms was permitted. The psychiatric and neurological status of the patients was assessed by PANSS, CGI, and ESRS scales. Results : 343(91%) of 377 patients completed the 8-week trial period. Clinical improvement, as defined by a 20% or more reduction in total PANSS score at end point, was shown by 81.3% of patients. The predictors of response to risperidone were associated older age, shorter duration of illness, fewer previous hospitalization. Risperidone had rapid onset of action ; a significant decrease of the total PANSS and three PANSS factor(positive, negative, general), and CGI was already noticed at the end of first week. For the ESRS, parkinsonism rating scores were significantly increased until week 4 comparing with baseline. Dystonia rating scores were significantly increased until week 1, and dyskinesia rating scores were not significantly changed during the study. Laboratory parameters including vital sign, EKG, hematological, and biochemical values showed no significant changes during the trial. Conclusions : This study suggests that risperidone is generally safe and effective against both the positive and negative symptoms in our group of patients.

Yoo, Dae Young,Shin, Bich Na,Kim, In Hye,Kim, Woosuk,Kim, Dae Won,Yoo, Ki-Yeon,Choi, Jung Hoon,Lee, Choong Hyun,Yoon, Yeo Sung,Choi, Soo Young,Won, Moo-Ho,Hwang, In Koo Kluwer Academic/Plenum Publishers 2012 Neurochem Res Vol.37 No.2

<P>Oxidative stress is one of the most important factors in reducing adult hippocampal neurogenesis in the adult brain. In this study, we observed the effects of Cu,Zn-superoxide dismutase (SOD1) on lipid peroxidation, cell proliferation, and neuroblast differentiation in the mouse dentate gyrus using malondialdehyde (MDA), Ki67, and doublecortin (DCX), respectively. We constructed an expression vector, PEP-1, fused PEP-1 with SOD1, and generated PEP-1-SOD1 fusion protein. We administered PEP-1 and 100 or 500 관g PEP-1-SOD1 intraperitoneally once a day for 3 weeks and sacrificed at 30 min after the last administrations. PEP-1 administration did not change the MDA levels compared to those in the vehicle-treated group, while PEP-1-SOD1 treatment significantly reduced MDA levels compared to the vehicle-treated group. In the PEP-1-treated group, the number of Ki67-positive nuclei was similar to that in the vehicle-treated group. In the 100 관g PEP-1-SOD1-treated group, the number of Ki67-positive nuclei was slightly decreased; however, in the 500 관g PEP-1-SOD1-treated group, Ki67-positive nuclei were decreased to 78.5% of the vehicle-treated group. The number of DCX-positive neuroblasts in the PEP-1-treated group was similar to that in the vehicle-treated group. However, the arborization of DCX-positive neuroblasts was significantly decreased in both the 100 and 500 관g PEP-1-SOD1-treated groups compared to that in the vehicle-treated group. The number of DCX-positive neuroblasts with tertiary dendrites was markedly decreased in the 500 관g PEP-1-SOD1-treated group. These results suggest that a SOD1 supplement to healthy mice may not be necessary to modulate cell proliferation and neuroblast differentiation in the dentate gyrus.</P>

Background: Focal adhesion kinase (FAK) and Src are non-receptor tyrosine kinases. FAK and Src play a critical role in inducing malignant transformation in tumor cells. Objectives: We performed immunohistochemical staining for total and phosphorylated forms of FAK and Src, to evaluate the role of FAK and Src in the development of premalignant and malignant skin lesions. Methods: A total of 59 facial skin samples (30 actinic keratoses, 10 Bowen``s diseases, 13 squamous cell carcinomas and six perilesional skins) were immunohistochemically stained for Ki-67, total (t) and phosphorylated (p) form of FAK and Src. Methods: A total of 59 facial skin samples (30 actinic keratoses, 10 Bowen``s diseases, 13 squamous cell carcinomas and six perilesional skins) were immunohistochemically stained for Ki-67, total (t) and phosphorylated (p) form of FAK and Src. Results: Cells positive for t-Src, p-Src-y530, t-FAK and pFAK-s722 were detected in premalignant intra-epithelial lesions (PELs) and squamous cell carcinomas (SCCs), but not in the perilesional skin. There was a tendency towards high correlation between Ki-67 and t-FAK or pFAK-s722, suggestive of the active role of FAK in cell proliferation. Conclusion: Our findings of higher t-Src and p-Src-y530 positive cells in PELs, as compared to SCCs (with higher Ki-67 level), are suggestive of the other role of Src in tumor formation and progression, which requires further investigation.

It has been proposed that cytokines may be involved in mediating the characteristic pathological changes in psoriasis, including epidermal hyperplasia, compromised keratinocyte differentiation, and dermal and epidermal infiltration by polymorphonuclear leukocytes and mononuclear cells. The purpose of this study os to assess the pattern of cytokine gene expression in psoriatic skin lesion. To investigate the cytokine expression pattern, we examined the transcripts of cytokine genes using reverse transcription and polymerase chain reaction (RT-PCR) method with 13 cytokine-specific primers. The Results were as follow; 1. Only the TGF-β gene was expressed in the normal skin. 2. IL-1α, IL-1β, IL-8, and TGF-β were detected in both lesional and perilesional psoriatic skin. The lesions showed more prominent expression. 3. IL-10 and GM-CSF were weakly detectable in three lesional psoriatic skin respectively, and IL-2R in two lesional psoriatic skin. 4. IL-2,IL-4,IL-5,IL-6 TNF-α, IFN-γ were not detectable on both lesional and perilesional psoriatic skin. Therefore, distinct differences in the cytokines gene expression were noted between normal and psoriatic skin. The patterns of cytokines gene expression in perilesional skin were similiar to those of lesional psoriatic skin.
