1.Labelling with Rhenium-188.
Korean Journal of Nuclear Medicine 1999;33(2):193-198
There is considerable interest in 188Re due to its favorable properties as a therapeutic radionuclide. 188Re and 99mTc act as a matched pair because of their similar chemical properties, and therefore methods of labeling with 99mTc can be applied to the labeling with 188Re. With appropriately chosen agents as carriers of 188Re, the labeling can be readily carried out using 188ReO4- in the presence of a reducing agent. 188Re radio pharmaceuticals based on 99mTc complexes have been synthesized and are currently being studied for clinical use. Some of them are shown to be suitable for therapeutic use and promising for radiotherapy in nuclear medicine.

In order to evaluate the prevalence of hepatitis B virus (HBV) and hepatitis C virus (HCV) infections in terminally failing hearts, we screened the explanted hearts of transplantation recipients for the presence of HBV DNA and HCV RNA. DNA and RNA extractions were taken from explanted failing hearts (N=7) and normal hearts (N=). Polymerase chain reaction (PCR) and in situ PCR of HBV or reverse transcription-polymerase chain reaction (RT-PCR) and in situ RT-PCR of HCV were performed. The positivity of HBV in failing hearts was 63% (17/27) and it was 50% (3/6) in normal hearts in PCR. There was no significant difference in the positivity of HBV DNA between failing and normal hearts. The positivity of HCV in failing hearts was 18.5% (5/27) and it was 16.7% (1/6) in normal hearts in nested RT-PCR. There was no significant difference in the positivity of HCV RNA between failing and normal hearts. HCV was very rarely observed in explanted terminally failing hearts and HBV was frequently found in both explanted failing hearts and normal hearts. We concluded that these viruses have little direct causal relationship with the development of heart failure.

OBJECTIVES: The purpose of this study was to investigate whether longitudinal changes in positive and negative symptoms affect cognitive functioning in chronic schizophrenia. METHODS: Sixty-eight patients diagnosed with DSM-IV schizophrenia were examined on two occasions over 6 months for symptoms and cognitive changes. Symptoms were measured by PANSS. Cognitive functions were examined for sustained attention, executive function, concentration and attention, and verbal memory and learning using Degraded Stimulus Continuous Performance Test, Wisconsin Card Sorting Test, Digit Span, and Rey Auditory Verbal Learning Test, respectively. Twenty control subjects were assessed to compare the cognitive scores of remitted schizophrenic patients. RESULTS: Patients showed significant improvement in symptoms and all cognitive tests after 6 months treatments. Significant improvements in positive and negative symptoms did not predict improvements in any aspect of cognitive functioning measured. Normal controls performed significantly better than remitted schizophrenic patients on all cognitive tests. The results show no relationship between change in symptoms and change in cognition in chronic schizophrenia. CONCLUSION: We suggest that symptomatic and cognitive impairment may be a distinct construct. These findings highlight the importance of treating cognitive impairment in addition to the clinical symptoms of schizophrenia.

PURPOSE: To develop a quality of life questionnaire in erectile dysfunction patients culturally adapted to Korea. MATERIALS AND METHODS: Final Korean version was developed by 1st, 2nd and 3rd intermediary Korean version. 1st intermediately Korean version was made by forward translation, meeting and reconcilation by feedback from Mapi research institute. 2ndary intermediary Korean version was made by backward translation, meeting and reconcilation by feedback from Mapi research institute. 3rd intermediary Korean version was made by patient by international harmonization, meeting and reconciliation by feedback from Mapi research institute. RESULTS: Patient instruction, quertion items from 1 to 22, partner questionnaire, global assessment question, and event log were translated into Korean both conceptually equivalent to the original and easily understood by the people through 1st, 2nd, 3rd intermediary and final Korean version. CONCLUSION: Korean version of quality of life questionnaire in erectile dysfunction patients was developed.

Brucellosis is a zoonosis caused by several species of Brucella. Brucellosis is usually an acute or sub-acute febrile illness that histologically develops granulomatous inflammation. Brucella prostatitis is a very rare complication and is usually accompanied by epididymo-orchitis. We now report a case of histologically proven granulomatous prostatitis due to Brucella without clinical evidence of epididymo-orchitis. A 61-year-old farmer presented with myalgia, low back pain, and fever. A needle biopsy of the prostate was performed due to symptoms of urinary frequency and high prostate specific antigen levels (17.3 ng/mL). Histologically, the prostate showed granulomatous inflammation without caseous necrosis. Polymerase chain reaction (PCR) studies of blood and prostatic tissue for Brucella were positive, while a PCR study for Mycobacterium tuberculosis was negative. The patient was treated with doxycycline and rifampin. A possibility of Brucella prostatitis should be considered in the differential diagnosis of granulomatous prostatitis or prostatitis of unknown origin associated with or without epididymo-orchitis.
