ABSTRACT
This paper describes the epidemiological characteristics of bovine brucellosis in Korea during January 2000~September 2004, which encompasses the period when the incidence of bovine brucellosis increased abruptly. Data from the National Animal Infectious Disease Data Management System were used for this study. A range of epidemiological measures was calculated including annual herd and animal incidence. During the study period, there were 1,183 outbreaks on 638 farms. In beef cattle, annual herd incidence increased from 0.2 (2000) to 11.5 (2004, to September) outbreaks per 10,000 and annual animal incidence varied between 3.4 (2000) and 105.8 (2004, to September) per 100,000, respectively. On 401 (62.9%) infected farms during this period, infection was eradicated without recurrence. Recurrence of infection was significantly higher on farms where abortion was reported (53.3%), compared to farms where it was not (30.0%). On beef cattle farms, infection was introduced most frequently through purchased cattle (46.2%). Based on the results of this study, the establishment and spread of brucellosis in the Korean beef cattle population were mainly due to incomplete or inappropriate treatment of aborted materials and the movement of infected cattle.

OBJECTIVES: The purpose of this study was to examine the reliability and validity of A ClinicianAdministered PTSD Scale(CAPS). METHODS: CAPS was administered to 28 PTSD subjects, 30 non-PTSD subjects, and 36 normal subjects. Interrater reliability for the CAPS was established by interviewing 10 PTSD subjects. The interviews were conducted by 2 interviewers simultaneously. The authors adminstered to all the subjects Impact of Event Scale(IES), Beck Depression Inventory(BDI), State Trait Anxiety Inventory I, II (STAI-I, II) for measuring concurrent validity. RESULTS: The value of Cronbach's alpha and interrater agreement were .95 and .89, respectively. The CAPS was highly correlated with IES(r=.80), BDI(r=.70), STAI-II(r=.56). But the CAPS was not correlated with STAI-I(r=.20). The CAPS showed an overall agreement with clinical diagnosis of 82.1%. CONCLUSIONS: The CAPS shows a reasonable degree of reliability and validity. The CAPS could be a valuable tool to diagnose PTSD.

The present study was undertaken to investigate the effect of acute administration of ethanol on production of cytokines such as IL-1j3, IL-2, IL-6, IL-10 and TNF-a, induction of penicillin V-induced active fatal anaphylaxis, and resistence to Salmonel/a typhimurium infection in mice. Ethanol administration into mice was performed by intraperitoneal injection of 0.5 ml of 20 % ethanol for 3 consecutive days before induction of cytokines with lipopolysaccharide (LPS), Con A or Salmone/la injection. Serum levels of cytokines were measured by ELISA. It was found that ethanol administration significantly inhibited both the serum levels of all cytokines examined and the resistance of mice to S. typhimurium. However, ethanol administration failed to prevent penicillin-induced fatal anaphylaxis. Taken together, the present results may need new insights in the diagnosis and treatment of various immunologically-mediated diseases.
