Azelastine, a phthalazinone derivative, is an antiallergic agent which demonstrates histamine H_1-receptor antagonist activity and also inhibits histamine release from mast cells following antigen and non-antigen stimuli. Thus, azelastine may be useful in the management of both asthma and allergic disorders. The purpose of the present study was to evaluate the bioequivalence of two azelastine hydrochloride tablets, Azeptin^TM (Bu Kwang Pharmaceutical Co., Ltd.) and Azela^TM (Kyung Dong Pharmaceutical Co., Ltd.), according to the guidelines of Korea Food and Drug Administration (KFDA). Eighteen normal male volunteers, 22.44±2.01 years in age and 61.99±6.18㎏ in body weight, were divided into two groups and a randomized 2×2 cross-over study was employed. After two tablets containing 1㎎ of azelastine hydrochloride per tablet were orally administered, blood was taken at predetermined time intervals and the concentrations of azelastine in serum were determined using HPLC with fluorescence detector. Pharmacokinetic parameters such as AUC_t, C_max and T_max were calculated and ANOVA test was utilized for the statistical analysis of the parameters. The results showed that the differences in AUC_t, C_max and T_max between two tablets were -6.45%, -2.60% and -7.14%, respectively, when calculated against the Azeptin^TM tablet. The powers (1-β) for AUC_t and C_max were 96.65% and 88.47%, respectively. Minimum detectable differences (Δ) at α=0.05 and 1-β=0.8 were less than 20% (e.g., 14.40% and 17.65% for AUC_t and C_max, respectively). The 90% confidence intervals were within ±20% (e.g., -14.87∼1.97 and -12.92∼7.72 for AUC_t and C_max respectively). Two parameters met the criteria of KFDA for bioequivalence, indicating that Azela^TM tablet is bioequivalent to Azeptin^TM tablet.

목적: 정신분열병 환자의 적응 상태와 증상 형성에 영향을 주는 것으로 생각되는 인지기능 상태를 주의력, 형태 인식, 단어에 대한 구별과 종합 기능을 평가해봄으로써 알아보고자 하였다 방법: 정신분열병 환자 27명과 대조군 27명을 대상으로 하였고, 평가 도구로써 주의력은 K-WAIS의 숫자외우기 문제로, 형태 인식은 K-WAIS의 모양 맞추기 문제와 숨은 그림 찾기로, 단어 기능은 K-WAIS의 공통성 문제와 단어 차이 검사로 각각 이루어졌다. 통계 처리는 SPSS 11.5를 이용하여 Chi-Square test와 Student's t-test로 검증을 하였다. 결과: 정신분열군은 숫자외우기, 숨은 그림 찾기, 모양 맞추기에서는 대조군보다 낮은 점수를 보였다. 단어 차이 검사와 공통성 문제에서는 양군에서 차이를 보이지 않았다. 결론: 본 연구에서 정신분열군의 인지 기능은 정상인 대조군에 비해 주의력과 형태 인식 기능이 유의하게 떨어져 있었으며, 단어들을 구분하고 종합하는 능력은 차이가 없었다. 이런 결과는 임상적으로 정신분열병에서 보이는 망상이 언어적인 측면에서는 어느 정도 전달이 되는 현상과 일치하지만 주의나 형태인지와 같은 기본적인 과정에서 장애가 있다는 추정을 하게 한다. Purpose: This study aimed to investigate the cognitive function in patients with schizophrenia by assessing attention, recognition of a shape, and verbal function. Methods: The subjects were 27 patients with schizophrenia group and 27 control group. Attention was assessed by the digit span task(K-WAIS subtest). The recognition of a shape was assessed by the object assembly task(K-WAIS subtest) and hidden figure task. Verbal function was assessed by Similiarities(K-WAIS subtest) and the different word task. Analysis was performed by the Chi-Square test and Student's t-test via SPSS 11.5. Result: Schizophrenia group had statistically lower scores than control group in digital span, hidden figure and object assembly. There was no difference between two groups in dimensions of difference in words and similarity. Conclusion: This study showed that patients with schizophrenia had impairments in attention and recognition of shape, and no difference between two groups in verbal ability. These explained the partial communicative function of delusion in verbal level. The formation of delusion might be related to the more basic elements such as attention and recognition of shape.

Acetyl-L-camitine (ALC), an endogenous component of the L-carnitine family, is a naturally existing molecule synthesized from L-carnitine (LC) by carmtine acetyl transferase. ALC has been shown to improve the cognitive performance of patients suffering from dementia of the Alzheimer's type and proposed for treating Alzheimer's disease in pharmacological doses. The purpose of the present study was to evaluate the bioequivalence of two ALC tablets, Nicetile^TM (Dong-A Pharmaceutical Co.) and L-Cartin^TM (Kuhn Il Pharmaceutical Co.), according to the guidelines of Korea Food and Drug Administration (KFDA). The ALC release from the two ALC tablets in vitro was tested using KP Ⅶ Apparatus Ⅱ method in various dissolution media (pH 1.2, 6.0 and 6.8). Twenty six normal male volunteers, 24.46±3.67 years in age and 64.45±5.54 ㎏ in body weight, were divided into two groups and a randomized 2×2 cross-over study was employed. After one tablet containing 500㎎ of ALC was orally administered, blood was taken at predetermined time intervals and the concentrations of ALC in serum were determined using HPLC with fluorescence detector. Because of the presence of endogenous ALC, the calibration was performed using dialyzed serum. The dissolution profiles of the two ALC tablets were similar in all the dissolution media. The pharmacokinetic parameters such as AUC_t, C_max and T_max were calculated and ANOVA was utilized for the statistical analysis of the parameters. The results showed that the differences in AUC_t, C_max and T_max between two tablets were 0.35%, 0.93% and 2.34%, respectively, when calculated against the Nicetile^TM tablet. The powers (1-β) for AUC_t and C_max were 98.72% and 85.48%, respectively. Minimum detectable differences (Δ) at α=0.05 and 1-β=0.8 were less than 20% (e.g., 13.21% and 18.42% for AUC_t and C_max, respectively). The 90% confidence intervals were within ±20% (e.g., -7.38~8.09 and -9.86~11.72 for AUC_t and C_max, respectively). These two parameters met the criteria of KFDA for bioequivalence, indicating that L-Cartin^TM tablet is bioequivalent to Nicetile^TM tablet.

Objuctives : Clinical utility of the Short Form of the Samsung Dementia Questionnaire (S-SDQ) as a screening instrument for Mild Cognitive Impairment (MCI). Methods : Three groups (n=27, Subjective Memory Impairment (SMI); n=41 MCI; n=79, Early Alzheimer's Di-sease(AD)) recruited from memory clinic were administered a battery of neuropsychological tests including S-SDQ and Korean version-Mini Mental State Examination (K.-MMSE). Results : S-SDQ, unlike the K-MMSE, had no association with the age and education ofthe subjects. Scores of S-SDQ was found to correlate (r=-.496) with scores of K-MMSE. Result of Receiver Operating Characteristic (ROC) analysis revealed that S-SDQ discriminated between the SMI and the MCI groups. Conclusion : S-SDQ may be a solution to the problem of contamination by education and age which affect traditional Cognitive screening instruments like K-MMSE, and it may be a useful tool for screening MCI.

We developed an occupational therapy tool to maintain and improve the cognitive function for the elderly who have senile dementia. 86 elderly people took a mininal mental state examination (MMSE) for the therapy to perform the occupational therapy, and divided into three groups based on avarage ages and MMSE values. The occupational therapy was treated three times per week for 10 weeks. The results showed that there were significant differences in the performing scores before and after the treatment ; the scores for the occupational therapy were increased significantly (p<0.001) and the performing time was shortened from 6-week throughout 10-week regimen. This study was to examine the effect on the activity of antioxidant enzymes by occupational therapy. The activities of antioxidant enzymes such as catalase, Glutathion-6-phosphate dehydrogenase (G6PDH), and superoxide dismutase (SOD) were increased to the normal standard by the occupational therapy for the elderly having dementia. The recovery of activities of antioxidant enzymes was obvious in severe demented elderly compared to those in normal or mild demented elderly. These results suggest that the occupational therapy had an beneficial effect on the protection against the oxidative stress especially for severe demented elderly, and the occupational tool need to be modified so as to improve the protection against the oxidative stress for normal and/or mild demented elderly.

This study was performed to develop a rapid test kit for pathogenic Staphylococcus in various samples. The rapid detection kit has been fabricated based on nitrocellulose lateral-flow strip. Colloidal gold and Staphylococcus antibodies were used as a tag and a receptor, respectively. Manually spotted Staphylococcus antibody and anti-mouse antibody on the surface of nitrocellulose membrane were used as test and control lines, espectively. Feasibility of the rapid kit to detect Staphylococcus aureus in samples were evaluated. The intensity of the color of the tes line started to increase with the samples in which higher concentration of the cells were contained. The sensitivity of the sensor was 106 cfu/mL Staphylococcus spiked in PBS. Also, the rapid test kit could detect 105 cfu/mL of Staphylococcus in chicken meat extract.

한국산 자리공 자리공 열매의 적색소를 이용한 식용색소 : Ⅱ. 활성 사포닌을 제거한 색소의 안정성과 가공적성 Ⅱ. Color Stability and Characteristics as Food Colorant of Saponin-Free Pokeberry Pigments

박용석,서지연,황혜정,박기환,윤광로 中央大學校 食糧資源硏究所 2003 食糧資源硏究所 論文集 Vol.15 No.1

우리나라산 자리공 열매의 색소 함량은 산지에 따라 건물 g당 48.56에서 62.16mg으로 천연색소 자원으로 높은 편이였으며 산지간의 격차가 크지 않아 자원성이 좋은 편이었ㄷ. 자리공 열매의 적색소를 absolute ethanol 침전법으로 분획하는 과정에서 활성 사포닌이 95% 이상 제거되며 이 색고 침전물을 silica gel column이나 Sephadex G-25 column으로 정제함으로서 색소의 순도를 높일 수 있었다. Absolute ethanol 처리와 column 정제법을 응용하여 활성 사포닌을 제거 한 실험용 자리공 열매색소 분획 모두 색소 안정성이나 가공적성에서 뚜렷한 차리를 보이지 않았다. 따라서 absolute ethanol만 처리한 색소제품이나 이를 column chromatography로 정제한 색소분획 모두 고순도의 천연색소 첨가물로의 응용 가능성은 분명하였다. 이들 활성 사포닌을 제거한 자리공 열매색소의 색소안정성과 가공적성은 다음과 같이 요약 할 수 있다. 즉, pH 안정범위는 4.8-6.0이었으며, 열에 대한 안정성을 조사한 결과는 4℃에서 45일 저장했을 때는 70%의 색소 잔존율을 나타낼 정도로 안정한 편이었지만 25℃에서는 10일째에서 70% 잔존율을, 50℃이상의 온도에서는 수 시간 정도에서 50%이하의 색소 잔존율을 보여 전반적으로 열 안정성은 불량한 편이었다. 한편 이들의 존재 하에서는 급격한 변색이 진행되었다. 자리공열매 색소에 대하여 ascorbic acid나 palmityl ascorbate의 첨가는 색소 잔존율에 큰 영향을 미치지 않았으며 chlorogenic acid, resocinol 그리고 catechin의 첨가도 마찬가지였다. 포도당, 과당, 맥아당, 설탕, 펙틴, 셀루로스 그리고 cyclodextrin 등의 탄수화물도 전혀 영양을 미치지 않았다. 1000ppm 이내의 EDTA나 citric acid, malic acid 또는 oxalic acid 등의 산도 미치지 않았다. 금속이온으로서, Ca^(2+)과 Al^(3+)의 첨가는 색소의 잔존율에 큰 영향을 미치지 않았으나, Cu^(2+)나 Fe^(2+)의 첨가는 심한 변색을 초래하였다. 자리공 열매즙의 무수 알코올 처리물(적색 색소 침전물)은 soft gel, firm gel 또는 캔디 등의 고형 식품에 잘 어울리고, 음료에서는 변색이 빠르게 진행되며, 특히 요구르트의 경우가 가장 민감하였다. 결론적으로 보면, 우리나라산 자리공 열매에서 활성 사포닌을 제거하고 확보한 색소제품은 사탕무의 betanin과 거의 같은 색소안정성과 가공적성을 보여 줌으로서 사탕무색소 첨가제인 beet red를 대신할 수 있으며 색소의 함량이나 순도라는 관점에서는 훨씬 우수할 것으로 사료된다. To evaluate the basic data on the color stabilities of saponin-free pokeberry pigment products, % remain of pigment were calculated from absorbances of solutions stored at various conditions. The pigment products were estimated to be very stable at pH 4.8-6.0. Thermostability of pH 5.0 solution of pigment products could be kept stable below 4℃. Addition of Cu2+ or/and Fe2+ decreased the % remain of pigment, whereas most food components had no offset the stability of pokeberry pigment. The color changes of some model foods having pokeberry pigment were checked by Hunter color differerence meter for 45 days. In solid foods like gels and candy the changes of color difference were very slower than that of model beverages. Application of pokeberry pigment to soft drink and yogurt were found to be effective at the refrigerated condition.
