PURPOSE: This study was conducted to investigate the effects of a cognitive behavior program on cognition, depression, and activities of daily living in elderly with Cognitive Impairment. METHOD: The research design was a nonequivalent control group pretest-posttest design. There were 21 subjects in the experimental group and 19 in the control group among 40 senior residents in a Hall for the elderly in the city of S. The subjects scores ranged from 15 to 23 on the MMSE-K(Korean Version of Mini-Mental State Examination) over age 65. The length of time for data collection and intervention was from Jun 26 to September 1, 2006. The cognitive behavior program consisted of 'Facing problem behavior', 'Searching for a coping skill', and 'Training in the coping skill'. It was applied to the experimental group twice a week, fifty minutes per session for six weeks. RESULT: Cognition(t=-4.232, p< .001) and IADL(t=-2.939, p< .01) in the experimental group were significantly higher than those of the control group. Depression in the experimental group was significantly less than the control group(t=3.870, p< .01). However, ADL in the experimental group was not significantly higher than the control group. CONCLUSION: These findings confirmed that a cognitive behavior program contributed to improving cognition and IADL, and to reducing depression in the elderly with Cognitive Impairment.

Scrub typhus, a mite-borne infectious disease, is caused by Orientia tsutsugamushi. Despite many attempts to develop a protective strategy, an effective preventive vaccine has not been developed. The identification of appropriate Ags that cover diverse antigenic strains and provide long-lasting immunity is a fundamental challenge in the development of a scrub typhus vaccine. We investigated whether this limitation could be overcome by harnessing the nanoparticle-forming polysorbitol transporter (PST) for an O. tsutsugamushi vaccine strategy.Two target proteins, 56-kDa type-specific Ag (TSA56) and surface cell Ag A (ScaA) were used as vaccine candidates. PST formed stable nano-size complexes with TSA56 (TSA56-PST) and ScaA (ScaA-PST); neither exhibited cytotoxicity. The formation of Ag-specific IgG2a, IgG2b, and IgA in mice was enhanced by intranasal vaccination with TSA56-PST or ScaA-PST. The vaccines containing PST induced Ag-specific proliferation of CD8 + and CD4 +T cells. Furthermore, the vaccines containing PST improved the mouse survival against O.tsutsugamushi infection. Collectively, the present study indicated that PST could enhance both Ag-specific humoral immunity and T cell response, which are essential to effectively confer protective immunity against O. tsutsugamushi infection. These findings suggest that PST has potential for use in an intranasal vaccination strategy.

The number of persons with HIV infection in Korea have increased steadily, total number of HIV infection in Korea were 478 on August, 1995. To investigate the clinicoimmunologic manifestation of AIDS in Korea, we reviewed complete blood counts (CBC), CD4 counts, serum beta2-microglobulin level, opportunistic infections and cause of death for 19 AIDS patients who had been admitted or visited at Pusan national university hospital during the period of January, 1990 to August, 1995. 1) The predominant mode of HIV transmission was heterosexual contact(18), other modes of transmission were homosexual contact(1). Clues of diagnosis of HIV infection were routine occupational health examination(14), and opportunistic infection symptoms such as fever, coughing(4). 2) Mean CD4 cell counts(/mm3) were 53 +/- 72 totally, 22 +/- 27 for 8 dead patients at mean 2 month before, 91 +/- 87 for 7 living patients. There were not significant difference(p>0.05). 3) Serum beta2-microglobulin(MG;ug/ml) was measured at 12 patients, mean serum beta2-MG level was4.8 +/- 7.3 totally, 7.1 +/- 10.3 for 6 dead patients at mean 1.3 month before, 2.5 +/- 0.4 for 6 living patients. There were not significant(p>0.05). 4) At CBC examination, WBC(/mm3) was 5,932 +/- 2,899 totally, 5,452 +/- 3,436 for 10 dead patients, 6,500 +/- 2,221 for 9 living patients(p>0.05). Hb(g/dl) was 11,4 +/- 2.8 totally, 9.4 +/- 1.8 for dead patients, 13.6 +/- 1.8 for living patients(p<0.05). Lymphocyte count(/mm) was 1,255 +/- 800 totally, 731 +/- 424 for dead patients, 1,838716 for living patients(p<0.05). ESR(mm/h) was 72 +/- 47 totally, 97 +/- 33 for dead patients, 47 +/- 47 for living patients(p<0.05). 5) Opportunistic infections had developed at 14 patients, candidiasis 7, pneumocystis carinii pneumonia 5, tuberculosis 3, cytomegalovirus infection 2, herpes zoster 3, toxoplasmosis 1, cryptococcal infection 2, bacterial pneumonia 5, and herpes simplex l. Malignant lymphoma had developed in 1 patient. 6) Mean survival interval from diagnosis of HIV infection to death was 32.8 +/- 19.1 months, and the most common cause of death was pneumocystis carinii pneumonia, and other causes of death were meningitis, bacterial pneumonia and AIDS-wasting syndrome. Based on these results, We concluded that CD4 counts, serum beta2-microglobulin level, Hb, total lymphocyte count and ESR in AIDS patients are specific laboratory markers of progression and prognosis of AIDS, the most common opportunistic infection was candidiasis, and the most common cause of death in AIDS patients was pneumocystis carinii pneumonia.
