The authors studied ED50 of bethanechol on the contractilities of the smooth muscles isolated from various organs of rat under the presence of atropine (a classical competitive blocker of cholinergic muscarinic receptor) or minaprine (a newly developed antidepressant drug) to investigate the peripheral anticholinergic effect of minaprine. The results were as follow: 1) There was no significant difference between ED50 of bethanechol in the control group and that under the presence of minaprine 10⁻⁸M and 10⁻⁷M in the smooth muscles isolated from the duodenum. 2) There was no significant difference between ED50 of bethanechol in the control group and that under the presence of minaprine 10⁻⁸M and 10⁻⁷M in the smooth muscles isolated from the ascending colon. 3) There was significant difference between ED50 of bethanechol in the control group and that under the presence of minaprine 10⁻⁸M and 10⁻⁷M in the smooth muscles isolated from the urinary bladder (P<0.01) 4) There was significant difference between ED50 of the atropine 10⁻⁸ and minaprine (10⁻⁸M) in the smooth muscles isolated from the urinary bladder (P<0.05).

The authors studied anxiety, using Zung's Self-Rating Anxiety Scale (SAS), in the subjects of 3,499 male and 1,335 female college freshmen of Yeungnam University. The authors collected the reports of SAS during the periods from January to February, 1986, and applied ANOVA and t-test on anxiety scores in order to compare them between various psychosocial factors, and sexes. The results are as follows: There was significant difference in the mean averages of total anxiety scores between male and female students: male students scored 32.91±7.70, female students scored 34.48±6.00, (P<0.001). The anxiety scores relating to the items of sweating, apprehension, restlessness, and insomnia were relatively higher in both groups. The anxiety scores relating to the items of faintness, mental disintegration, tremors, dizziness were lower in both groups. Thirty-nine male students (1.1%) showed seriously high anxiety scores of 50 or higher, while twenty-one female students (1.6%) showed the same scores. So the authors inferred that the features of anxiety symptoms were much the same in our country, but female showed more various symptoms and higher level of anxiety than males. Male students attending in pharmacy showed higher level of anxiety scores (P<0.01). There was a strong tendency toward higher anxiety scores in the students who were dissatisfied with their home atmosphere, colleges, department and familiarity of parents, and those who had pessimistic views of self image in the past, present, or future, in both groups (P<0.001).

4.Induced Pluripotent Stem Cells: Next Generation Stem Cells to Clinical Applications.

Hanyang Medical Reviews 2015;35(4):190-195
Induced pluripotent stem cells (iPSC) are specially manipulated cells from somatic cells by the introduction of four factors that are reprogrammed. The properties of iPSC are similar to embryonic stem cells (ESC) characteristic of self-renewal and pluripotency. The technology of reprogramming somatic cells to iPSC enables the generation of patient-specific cells that can be used as powerful tools for drug screening, in vitro models for human disease and autologous transplantation. The iPSC technology provides a priceless resource for regenerative medicine but there are still changing obstacles over the safety of iPSC in avoiding induction of tumorigenicity and maintaining high purity of re-differentiated cells from iPSC to produce more functional cells for cell therapy. A variety of methods to overcome the limitation of iPSC application applied in the clinical setting have been developed. In this review, we summarize the recent progress in iPSC generation and differentiation techniques to facilitate clinical application of iPSC with future potential in regenerative medicine.

Using Zung's self-rating depression scale, the authors studied depression in 310 elderlies residing in the 9 home for the aged (HFA) in Kyungbuk area, and 234 elderlies living in Taegu city and 107 elderlies attending a Life-long education program in Taegu, which serve as a control group, Community resident elderlies (CRE). The research had been administered during the period from June to August, 1986. The results were as follows: 1. The mean scores of male, female, and the total of the elderlies in HFA were 38.95±11.55, 44.18±14.15, and 42.8±13.7 respectively while CRE marked 40.8±11.3 for male, 45.2±12.0 for female, and 43.4±11.9 for the total. Therefore there were significant differences between male and female in both groups (<0.01, p<0.001), though no significant difference between the two groups. However, the depression score of elderlies in HFA might be much higher than that of CRE if 81 elderlies (14.2%) in HFA who had been left out of the statistical evaluation due to their having severe depression, organic brain syndrome, or pseudoementia, etc had been included. 2. The score distribution by items for the elderlies in HFA were from highest scores hopelessness, worthlessness, emptiness, decreased appetite, confusion, while for CRE, hopelessness, decreased appetite, psychomotor retardation, indecisiveness, and worthlessness, Elderlies in HFA showed significantly high scores in depressed mood, weight loss, suicidal rumination (ideation) and psychomotor excitement, while CRE showed significantly high scores in decreased appetite, psychomotor retardation, indecisiveness, and dissatisfaction. 3. Elderlies who scored over 50 numbered 10 males (16%), 57 females (34%), and total of 67 (29%) in HFA and 28 male (21%), 77 females (37%), and total of 105 (31%) in CRE: female showed higher seores in both groups. 4. Psychococial factors such as getting older (respectively p<0.01, p<0.01), being Buddhist (respectively p<0.01, p<0.01), and monthly pocket money less than ₩30,000 (respectively p<0.001, p<0.001) were found to have a noticeable impact on the depression level of the elderlies in both groups. Factors such as illiteracy (p<0.001), monthly pocket money less than ₩10,000 (p<0.05), and having no family (p<0.01) recorded significantly higher scores among CRE than the elderlies in HFA.

This study was intended to analyze the relation between the psychic traumatic experience and the psychological health of the aged. The authors carried out this study by means of the combined anxiety-depression scale (CADS) and the preadolescence traumatic experience scale (PTES) with 278 aged men and women residing in Taegu from September to October 1988. The results were as follows: 1. Based on the scores evaluated by CADS, the scores of the both groups showed that comparative group was accounted for 40.15±6.19, while the experimental group for 57.75±6.37, which showed significantly higher score in the experimental group (p<0.001). 2. The experimental group showed significantly higher early experience score than the comparative group in the dietary difficulty, alcoholism among family members, disunion between husband and wife, trouble between mother and children, early mother loss, parent's indifference and unwanted birth (p<0.001). 3. The experimental group showed higher early experience score than the comparative group by sex, age, marital status and grown location (p<0.001). 4. When the subjects were included in the unemployed and in the middle or low classes and their parents were engaged in agriculture and commercial business and believing in buddhism or no-religion, showed higher experience score (p<0.001).

BACKGROUND: The cornified cell envelope (CE) is a unique structure found in the terminal differentiation of the skin. The precursor proteins of the CE are composed of many candidate structural proteins, among which invalucrin and filaggrin are important ones to participate in the complicated process of forming, the complex structure. OBJECTIVE: The purpose of this study was to evaluate the usefulness of expression of involucrin and filaggrin as markers of terminal differentiation in various skin disorders including tumors. METHODS: Immunohistochemical studies were performed in the formalin-fixed, paraffin-embedded skin samples of non-tumors (41 cases) and tumors (43 cases).

We report two cases of murine typhus diagnosed by indirect immunofluorescent test. The patients showed cardinal symptoms and signs such as fever and chill, general myalgia, intractable headache and typical rash. Laboratory values and histopathologic findings were compatible with murine typhus. The oral administration of doxycycline improved dramatically the clinical manifestations of the two CCLSPS.
