<P><B>Objectives: </B> To determine whether detection of prostate stem cell antigen (PSCA) expression has potential for molecular staging in prostate cancer (PCa), we examined the relationship between established prognostic factors, biochemical recurrence (BCR) and PSCA expression.</P><P><B>Methods: </B> This study was comprised of 66 patients who underwent radical prostatectomy for the treatment of PCa. We employed reverse transcriptase‐polymerase chain reaction (RT‐PCR) to detect PSCA mRNA‐bearing cells in peripheral blood, and used immunohistochemical (IHC) techniques to identify PSCA protein expression in microarrayed tissue.</P><P><B>Results: </B> PSCA‐mRNA was detected in the peripheral blood of nine (13.6%) patients by RT‐PCR. Whereas 3.2% of patients with low‐grade disease were PSCA positive, 22.9% of patients with high‐grade disease were PSCA positive (<I>P</I> = 0.030). There was also a significant relationship of RT‐PCR PSCA positivity to whether or not the tumor was confined to the prostate. Whereas only 6.8% of patients with prostate‐confined disease were RT‐PCR PSCA positive, 27.3% of extraprostatic diseases were RT‐PCR PSCA positive (<I>P</I> = 0.022). IHC studies of tumor tissue microarrays demonstrated that PSCA expression intensity was related to both extraprostatic extension (<I>P</I> = 0.014) and positive surgical margin (<I>P</I> = 0.053). Whereas 23.8% of prostate‐confined diseases were high intensity, 54.5% of extraprostatic diseases were high intensity. BCR developed in seven patients (10.6%) during the follow‐up period (median, 16.2 months; range, 9–25 months). Prognostic factors increasing the risk of BCR included: seminal vesicle invasion (<I>P</I> = 0.004), extraprostatic disease (<I>P</I> = 0.019), lymphovascular emboli (<I>P</I> = 0.036) and RT‐PCR PSCA positivity (<I>P</I> = 0.004) in univariate analysis.</P><P><B>Conclusions: </B> We were able to detect PSCA mRNA‐bearing cells in peripheral blood by RT‐PCR, and also identify PSCA protein expression in tumors by IHC analysis of tissue microarrays. RT‐PCR PSCA positivity in peripheral blood may be a potential modality for molecular staging of PCa.</P>
Butterfly Fauna of the Gwangneung Forest, Korea
변봉규,Young June Lee,Gab-Jae Weon,Jung-Dal Sohn 한국응용곤충학회 2005 Journal of Asia-Pacific Entomology Vol.8 No.2
As a result of the review of past literature and the authors’survey, 148 species of butterflies in the Gwangneung Forest are listed, which has been well known as a natural relic of Korea. Eight species such as Isoteinon lamprospilus Felder and Felder, Favonius cognatus Staudinger, F. korshunovi (Dubatolov and Sergeev), Pseudozizeeria maha (Kollar), Spindasis takanonis Matsumura, Aldania themis (Leech), Argynnis zenobia Leech and Erebia wanga Bremer are newly added to this fauna based on the surveys during 2000-2004. This list incorporates taxonomic changes and corrections in scientific names and the deletion of 11 species erroneously recorded. Historical review and discussions on the tendency of occurrences for some species are also provided.

밤나방과에 Hadennia obliqua (Wileman), Zanclognatha lui Han and Park, Premusia intrahens Walker, and Cucullia hostiiis Broursin 등 4종이 한국에서 처음으로 보고 된다. 이들 미기록 4종에 대해 성충의 형태적 특징과 암수생식기를 간략히 기술하고 도해한다. In the present study, we reports four species of Noctuidae are reported for the first time from Korea: Hadennia obiiqua (Wileman), ZancloEnatha lui Han and Park, Premusia intrahens Walker, and Cucullia hostilis Broursin. The adults and genital characteristics of the species are briefly redescribed with illustrations and their biological and distributional notes are given as necessary.
