  • Hemolymph protein patterns of silkworms in terms of short and long life span were analyzed by native- and SDS-polyacrylamide gel electrophoresis (PAGE) with the developmental stages. From the native-PAGE patterns of silkworm major hemolymph proteins there were varietal differences on the first day of the pupal stage and were classified into there groups MHP-a, b and c SA 10, JAM109 and J037 were grouped into MHP-Ⅰ, Hangang, Chungmun and Daizo(sdi) into MHP-Ⅱ and NTZN, Sulak, Qoichuk and PR varieties into MHP-Ⅲ group. It was found that the MHP in each group revealed similar patterns and changes with development of pupal stage. In the first day of adult, MHP-c was clearly detected in both female and male of the Daizo(sdi), but not in the J037, indicating that there was significantly varietal differences in electrophoretical protein pattern. In addition, the results of protein pattern of hemolymph by SDS-PAGE showed also varietal differences in the concentration of hemolymph protein.

  • Object:The authors compared the attention-deficit hyperactivity(ADH) symptoms in childhood of adult male patients with bipolar disorder, schizophrenia and normal control subjects and attempted to find out whether attention-deficit hyperactivity disorder and bipolar disorder are related each other. Method:The authors compared ADH symptoms in childhood assessed with Wender Utah Rating Scale(WURS), selected 25 items of WURS(WURS-25), and Parent Rating Scale(PRS), and compared them between 26 bipolar, 29 schizophrenic, and 27 normal control subjects. Result:The subjects with bipolar disorder had significantly higher mean score of WURS compared with normal control group(One-way ANOVA, duncan test, WURS:DF=2, F=3.77 p=0.027), and the differences between the mean scores of WURS-25 and PRS of bipolar subjects and the other two groups were also highly significant(One-way ANOVA, Duncan test, WURS-25:DF=2, F=4.24 p=0.0178, PRS:DF=2, F=13.97 p<0.001). The mean scores of WURS, WURS-25, and PRS of schizophrenic subjects were higher than those of normal control group, though not significant. WURS and PRS were correlated for subjects with bipolar disorder(r=0.7495) and the normal control(r=0.5305), and there was no correlation for schizophrenic subjects. Conclusion:The ADH symptoms in childhood were much more evident for adult bipolar subjects than schizophrenic and normal control subjects. And these results are very suggestive that there might be some relationship between bipolar disorder and attention-deficit hyperactivity disorder and these two disorders might have a shared common pathophysiology which needs further study.

  • Background: High incidence of breast cancer and its fatal effect has reached an alarming stage across the globe, including the third world countries. Many factors have been reported to be associated with the development of breast cancer but detailed structural and functional information is missing. CA 15-3 is one of the known potential tumor marker of breast cancer; however little is known about structure and functional site of this protein. Present study aims to investigate the functional role of CA 15-3 in breast cancer, especially in development and metastasis. Material and Methods: Hundred female breast cancer patients confirmed by histopathological reports were included in the study. Their physiological characters were recorded in a performa. Enzyme linked immunosorbent assay (ELISA) technique was used to estimate serum CA 15-3 level. Immunohistochemistry was done for estrogen (ER), progesterone (PR) and Her2/neu receptors expression. Results: The study revealed the details of physiological characteristics of female breast cancer. Mean age was $37.72{\pm}5.99$ and $55.05{\pm}7.28$ years and serum CA 15-3 (MUC1) level was $60.47{\pm}8.59$ and $63.17{\pm}4.58$ U/ml in pre and post-menopause respectively, and both groups of women had sedentary life style. Their receptor status especially of progesterone, estrogen and HER-2/neu were positive in 50% of premenopausal women and 65% of postmenopausal women. Conclusion: There are multiple physiological factors promoting breast cancer. High serum CA 15-3 level and hormonal imbalance of ER, PR and Her2/neu appears to be the main cause of breast cancer. It may be possible that the functional sites of these proteins may be altered which may increase the chances of metastasis in breast cancer.

  • The effect of ${\alpha}$-, ${\beta}$- and ${\gamma}$-picolines on the stereochemistry of the coordination compounds of lanthanide(III) nitrates derived from 4[N-(furfural)amino]antipyrine semicarbazone (FFAAPS) has been studied. The general composition of the present coordination compounds is [Ln(FFAAPS)$(NO_3)_3$Pic] (Ln=La, Pr, Nd, Sm, Gd, Tb, Dy or Ho and Pic=${\alpha}$-, ${\beta}$- or ${\gamma}$-picolines). All these coordination compounds have been characterized by elemental analyses, molecular weight, molar conductance, magnetic susceptibility, infrared and electronic spectra. The infrared studies suggest that the FFAAPS behaves as a neutral tridentate ligand with N, N, O donor while ${\alpha}$-, ${\beta}$- or ${\gamma}$-picoline is coordinated to the lanthanide(III) ions via heterocyclic N-atom. Nitrates are bicovalently bonded in these compounds. From the electronic spectral data, nephelauxetic effect (${\beta}$), covalence factor ($b^{1/2}$), Sinha parameter (${\delta}%$) and the covalence angular overlap parameter (${\eta}$) have been calculated. Thermal stabilities of these complexes have been studied by thermogravimetric analysis. The coordination number of lanthanide(III) ions in the present compound is found to be ten. The antibacterial studies screening of the primary ligand FFAAPS and the complexes showed that the present complexes have moderate antibacterial activities.

  • Background : Recently, there have been several studies showing that irinotecan hydrochloride, a topoisomerase I inhibitor, is effective against extensive disease(ED) small cell lung cancer (SCLC). We conducted a phase II trial to evaluate the efficacy and toxicity of irinotecan plus cisplatin as a 1st line therapy for both limited and extensive disease SCLC. Methods : The study was conducted between January 2002 and June 2004. Patients were treated with $60mg/m^2$ irinotecan on day 1, 8, 15 and $60mg/m^2$ cisplatin on day 1, every 4 weeks. During concurrent thoracic irradiation for limited disease (LD)-SCLC patients, dose of irinotecan was reduced to $40mg/m^2$. Prophylactic cranial irradiation was given to patients with complete remission (CR) after chemotherapy. Results : Median ages of LD- and ED- SCLC were 64 years and performance status (PS) was 0-2. In patients with LD-SCLC, the response rate after concurrent chemoradiotherapy was 85% (CR, 6; Partial response [PR], 11). The median survival was 20 months (95% CIs, 15.6 to 24.4) with 1-and 2-year survival rates of 85% and 35%, respectively. Median progression free survival (PFS) was 12 months (95% CIs, 6.2 to 18.1) with 1- year PFS of 36%. In ED-SCLC, the response rate was 83.4% (CR, 1; PR, 14). The median survival was 14.5 months (95% CIs, 8.8 to 20.1) with 1-year survival rates of 75%. Median PFS was 6.3 months (95% CIs, 5.6 to 7.1) with 1- year PFS of 20%. The major toxicities (grade 3 or 4) of this regimen included leukopenia, anemia, thrombocytopenia, nausea/vomiting, and diarrhea without life threatening complication. Conclusion : Our data shows that the combination of irinotecan plus cisplatin as a first line therapy is effective and tolerable in the treatment of both LD- and ED- SCLC.

  • Purpose: Premenstrual syndrome(PMS) is a collection of physical, psychological and emotional symptoms related to a women's menstrual cycle. The symptoms are related with Autonomic Nervous system. The purpose of this study is to investigate the activity of Autonomic Nervous system in women with premenstrual syndrome(PMS) by using Heart Rate Variability(HRV). Methods: We studied 26 patients visiting ㅇㅇ hospital from 26th December 2005 to 26th April 2006. Activity of Autonomic Nervous system was assesed by means of Heart Rate Variability(HRV). The subjects were categorized in two groups, PMS group(10) and non-PMS group(16). We studied the difference of HRV between two groups by Mann-Whitney U-test using SPSS for windows (version 12.0). Results: SDNN of PMS group was non-significantly lower than non-PMS group. RMS-SD of PMS group was significantly lower than non-PMS group. Mean PR of PMS group was non-significantly higher than non-PMS group. TP, VLF, LF, HF norm of PMS group was non-significantly lower than non-PMS group. HF of PMS group was significantly lower than non-PMS group. LF norm, LF/HF ratio of PMS group was non-significantly higher than non-PMS group. Conclusion: The results suggest that PMS can be related to decreased activity of parasympathetic nervous system. HRV can be useful to diagnose PMS. The more studies to diagnose PMS would be needed.

  • The development of biomarkers of reproductive medicine is still in its infancy because many black boxes are still present in reproductive medicine. Novel approaches to human infertility diagnostics and treatment must be developed because reproductive medicine has lagged behind in the implementation of biomarkers in clinical medicine. Despite the dearth of the available literature, the current rapid pace of publications suggests that this gap will soon be filled therefore; this review is a $pr\acute{e}cis$ of the research that has been done so far and will provide a basis for the development of biomarkers in reproductive medicine.

  • The present study examined the effects of self-construal and message orientation on value advocacy advertising. An experiment of college students was conducted to investigate relationship between the attitude toward advocacy advertisements and the purchase intention. The results showed that people with interdependent self-construal have more positive attitude toward the advocacy advertisements than people with independent self-construal. The interaction effects between self-construal and message orientation on the value advocacy advertisements were not found significant. However, it was found that even people with independent self-construal showed more positive attitude toward the advocacy advertisement with others-orientation messages than the advertisement with self-orientation messages in value advocacy advertising. Based on the findings, theoretical and managerial implications for value advocacy advertising were discussed.

  • Let R be a commutative ring with identity. An R-module M is said to be w-projective if $Ext\frac{1}{R}$(M,N) is GV-torsion for any torsion-free w-module N. In this paper, we define a ring R to be w-semi-hereditary if every finite type ideal of R is w-projective. To characterize w-semi-hereditary rings, we introduce the concept of w-injective modules and study some basic properties of w-injective modules. Using these concepts, we show that R is w-semi-hereditary if and only if the total quotient ring T(R) of R is a von Neumann regular ring and $R_m$ is a valuation domain for any maximal w-ideal m of R. It is also shown that a connected ring R is w-semi-hereditary if and only if R is a Pr$\ddot{u}$fer v-multiplication domain.

  • The base-induced elimination of N-protected 2-(bromomethyl)pyrrolidines 12a-c with KHMDS in THF at -78$^{\circ}C$ for 1h gave exocyclic enamines 13a-c. The acidic catalyzed pr otonation on ${\beta}$-carbon atom of 2-(methylene)pyrrolidines 13a-c with $H_3PO_4$ formed endocyclic N-iminium intermediates 14(or 15). Nucleophilic attack of alpha-carbon atom and hydrolysis of N-iminium ion gave carbocationic adduct (aminoalcohol) 16 from which 5-amino-2-pentanones 17a-c were formed after deprotonation.
