  • Purpose: This study was conducted to compare the level of depression, self-esteem and mother-adolescent (M-A) communication perceived by both mothers and adolescents between the early adolescent (E-A) group and the late adolescent (L-A) group; and to examine the actor effect and the partner effect of self-esteem and M-A communication on depression in mothers and adolescents. Methods: Participants were 107 Kirogi families who resided in the Midwest region of the U. S. Data were collected from September, 2008 to March, 2009 using the scales of Center for Epidemiologic Studies Depression (CES-D), Self-esteem and Parent-Adolescent Communication Inventory. Results: Mothers in E-A group reported higher scores on depression than mothers in L-A group. Adolescents in L-A group reported higher scores on depression and lower scores on self-esteem than adolescents in E-A group. In the E-A group, mothers' selfesteem had big actor effect on mothers' depression and partner effect on adolescents' depression. In the L-A group, selfesteem of mothers and adolescents had actor effect on their depression respectively without partner effect. M-A communication of mothers influences mothers' depression negatively and adolescents' depression positively. In both group, M-A communication influences their depression with mediating effect of self-esteem. Conclusion: To promote Kirogi families' mental health, programs for mothers and adolescents should be developed differently according to adolescents' development stage.

  • Objectives: The purpose of this study is to obtain the differential variable and learning effect of the serial position effect, targeting individuals aged 60 years and over. A total of 89 individuals were categorized into the following groups: Alzheimer's group, vascular dementia group, elderly depression group, and normal group. Methods: Considering the size of the groups used for comparison, of the total 89 participants, 28 were in the Alzheimer's group, 24 in the vascular dementia group, 16 in the elderly depression group, and 21 were randomly chosen for the normal group. In the CERAD-K word list memory test, 10 words were shown to the subjects. We then asked them to freely recall the words. After changing the order of the words three times, the same process was followed. Results: First, a significant difference was observed among the groups in terms of word recalling rate. The analysis conducted afterward showed that, as predicted, the depressed group showed significantly better performance in recalling the words. Second, the vascular dementia patients and the Alzheimer's patients showed, as predicted, better recall of the largest recency region of words shown. Third, the normal group and the elderly depressed group showed a high-performance rate, proving that the reiterative method can contribute to the recalling process. Thus, we demonstrated that the Alzheimer's group showed the deterioration of short memory recalling skills and the elderly depressed showed deteriorated output performance skill.

  • The purpose of this research is to investigate the synergistic effect of herb medicines with hydrocortisone and the regulation effect on the immune system of Onbitang and Dangguijakyaksan at the supernatant of PHA-P stimulated PBMC in the patients with minimal change nephrotic syndrome(MCNS). From the measurement of the concentration rate of IL-4, sCD23 and IL-13, the experiment yielded the following results : The Onbitang group showed a greater tendency to suppress IL-4 and IL-13 levels in MCNS group with no statistical significance. It showed very strong suppression in soluble CD23 compared with control group in MCNS group. The Dangguijakyaksan group, though not statistically significant, was inclined to suppress IL-4 level in MCNS group. It shows stronger suppression in sCD23 and IL-13 levels than these of control group in MCNS group. As for the synergistic effect, the group of hydrocortisone with herb medicines(Onbitang or Danguijakyaksan) produced more suppressive effect to IL-13 level in MCNS group than that of hydrocortisone-only group. They also tended to suppress sCD23 and IL-4 levels, though no statistical significance can be given. As to the suppressive effect of 1L-13 level, the group of Onbitang with hydrocortisone showed an increase of 22.6%, while the group of Dangguijakyaksan with hydrocortisone showed 14.7%. So Onbitang is more effective than Dangguijakyaksan. From the above results, a combinative treatment(herb medicines with hydrocortisone) can be an alternative method to substitute for steroid therapy. It can be a more effective therapy than steroid-only therapy because it is expected to reduce side effects and it shows more special effect to suppress IL-13 level. Based on the present results, further investigation concerning the serum IgE elevation is needed.

  • Objectives : This study was aimed to define the protective effect of Tissue Cultured Root of Wild Ginseng (CWG) against doxorubicin (Doxo) toxicity, and investigate the anti-tumor synergic effect of CWG in combination with Doxo in tumor-bearing C57BL/6 mice. Methods : Tumor-bearing mice were established by single inoculation with B16/F10 melanoma cells (2$\times$10$^6$/ml) subcutaneously. Tumor-bearing mice (tumor volume between 50-100 mm$^3$) were selected and divided them into control, Doxo, and Doxo+CWG group. Mice of Doxo group were received with Doxo (4 mg/kg of B.W.) intraperitoneally at 0, 4, 8 days after starting the experiment. Mice of Doxo+CWG group were received CWG water extract during 12 days in combination with Doxo treatment. The body weight, tumor volume, tumor weight, and organ weight (heart, liver, kidney, and testis) were measured. And serum SPK, GOT and creatinine values were analysed. Results : The volume and weights of tumor masses in Doxo group were decreased significantly compared with the those of control group. And the those of Doxo+CWG group were not significantly different from the those of Doxo group. Whereas the weight of body, liver, kidney and testis in Doxo+CWG group were increased significantly compared with the those of Doxo group. The level of serum CPK and GOT in Doxo group were increased compared with the those of control group. But the value of Doxo+CWG group were decreased significantly compared with the values of Doxo group. Conclusions : These results suggest that CWG has protective effect against doxorubicin toxicity. And these effect is guessed that is caused in augmentation of vital energy.

  • Objectives : To find effects of acupuncture, electro-acupuncture, low level He-Ne laser therapy(LLLT) at $TE_5$, $GB_{41}$ in the neuropathic pain. We made experiment on rats ligated L5 spinal nerve like general herniation of nucleus pulposus(HNP). Methods : A model of neuropathic pain was made by isolating Left 5th lumbar spinal nerve of rats. Three days after the neuropathic surgery, acupuncture and LLLT, electro-acupuncture was injected at $TE_5$, $GB_{41}$ one time a day for a week. Each group was divided two. one is opposite side performed the surgery which is right, another is left side performed the surgery. After that, the author examined the withdrawal response of neuropathic rats' legs by van Frey filament and acetone stimulation. And also the author examined c-Fos, Nociceptin and KOR-3 in the midbrain central gray of neuropathic rats. Results : As we have observed the effect of mechanical allodynia, LT-R group were diminished on 6th day compared with control group, EA-L group, EA-R group and LT-L group were diminished on 7th day compared with control group. As we have observed the effect of cold allodynia, EA-R group were diminished on 6th day, 7th day compared with control group. As we have observed the effect of activity of c-Fos in the central gray part, EA-R group and LT-R group were diminished compared with control group. As we have observed the effect of activity of Nociceptin in the central gray part, EA-R group were a little increased compared with control group but it is not reliability. As we have observed the effect of activity of KOR-3 in the central gray part, EA-R group were significantly increased compared with control group. Conclusions : We have noticed that effect of acupuncture at opposite side of sickness and powerful stimulation could be more effective, because of EA-R group have more controllable effect all test we have done on the other hand EA-L group have only effect on mechanical allodynia. This study can be used in clinical therapy for neuropathic pain. But it is not reliability that Nociceptin have effectively to control pain. Therefore We have to follow up about that.
