<P>Seoritae is a type of black soybean that is known to have health-promoting effects due to its high isoflavone and anthocyanin contents. We evaluated whether Seoritae extract (SE) had beneficial effects on the reduction of prostate weight in a rat model of benign prostatic hyperplasia (BPH). BPH was induced by intramuscular injections of testosterone enanthate once a week for 5 weeks in Sprague-Dawley rats, and rats were treated with or without daily oral doses of SE during BPH induction. After 5 weeks, the oxidative stress (superoxide dismutase and 8-hydroxy-2-deoxyguanosine), apoptosis (caspase-3), and activity of 5-alpha reductase were evaluated in the serum and prostate. The SE treatment group showed a significant decrease in prostate weight, oxidative stress, apoptosis, and 5-alpha reductase activity compared to the nontreated BPH group. These results show that SE is effective in decreasing the weight and proliferation of the prostate, and suggest that SE may be an effective treatment for BPH.</P>

<P>Varicocele is the most common cause of primary male infertility and is associated with oxidative stress. The aim of the present study was to investigate the effects of anthocyanin on a rat model of varicocele. Twenty-four male rats were divided into four experimental groups: a normal control group, a varicocele-induced control group and two varicocele-induced groups treated with either 40 or 80mgkg(-1), p.o., anthocyanin for 4 weeks. Varicocele was induced by the partial obstruction of the left renal vein. After 8 weeks, the testes and epididymides from rats in all groups were removed, weighed and subjected to histological examination and semen analysis. Apoptosis in the testes was determined by terminal deoxyribonucleotidyl transferase-mediated dUTP-digoxigenin nick end-labelling (TUNEL) and oxidative stress was assessed by measuring 8-hydroxy-2'-deoxyguanosine (8-OHdG) levels. Although no significant differences in sperm counts were observed among the groups, anthocyanin treatment of the varicocele-induced groups resulted in significantly increased testes weight, sperm motility and spermatogenic cell density (P<0.05). Anthocyanin treatment also significantly decreased apoptotic body count and 8-OHdG concentrations (P<0.05). We suggest that the antioxidant effect of anthocyanin prevented the damage caused by varicocele-induced reactive oxygen species.</P>

We present BV CCD photometry for the open clusters Czernik 24 and Czernik 27. These clusters have never been studied before, and we provide, for the first time, the cluster parameters; reddening, distance, metallicity and age. Czernik 24 is an old open cluster with age $1.8{\pm}0.2Gyr$, metallicity $[Fe/H]=-0.41{\pm}0.15dex$, distance modulus $(m-M)_0=13.1{\pm}0.3mag$ ($d=4.1{\pm}0.5kpc$), and reddening $E(B-V)=0.54{\pm}0.12mag$. The parameters for Czernik 27 are estimated to be $age=0.63{\pm}0.07Gyr$, $[Fe/H]=-0.02{\pm}0.10dex$, $(m-M)_0=13.8{\pm}0.2mag$ ($d=5.8{\pm}0.5kpc$), and $E(B-V)=0.15{\pm}0.05mag$. The metallicity and distance values for Czernik 24 are consistent with the relation between the metallicity and the Galactocentric distance of other old open clusters. We find the metallicity gradient of 51 old open clusters including Czernik 24 to be ${\Delta}[Fe/H]/{\Delta}R_{gc}=-0.064 {\pm}0.009dex\;kpc^{-1}$.

Laparoscopic live donor nephrectomy (DN) has been established as a useful alternative to the traditional open methods of procuring kidneys. To maximize the advantages of the laparoendoscopic single-site (LESS) method, we applied natural orifice specimen extraction to LESS-DN. A 46-year-old woman with no previous abdominal surgery history volunteered to donate her left kidney to her husband and underwent single-port laparoscopic DN with transvaginal extraction. The procedure was completed without intraoperative complications. The kidney functioned well immediately after transplantation, and the donor and recipient were respectively discharged 2 days and 2 weeks postoperatively. Single-port laparoscopic DN and transvaginal graft extraction is feasible and safe.

Transumbilical single-port laparoscopic donor nephrectomy (SPLDN) is a novel, rapidly evolving, minimally invasive treatment modality for kidney transplantation. This method causes minimal parietal injury, has cosmetic advantages, and allows rapid recovery because of low postoperative pain and short hospital stay. Like other abdominal surgeries, when conducted by experienced laparoscopic surgeons, it can meet the same graft requirements as conventional laparoscopic surgery. Here, we report the first two cases of transumbilical SPLDN at Daejeon St. Mary’s Hospital, The Catholic University of Korea. We used the umbilicus as a common path for laparoscopic procedures and as a route for specimen retrieval. The operating times were 230 and 265 minutes in cases 1 and 2, respectively. No intra- or postoperative complications were noted. In case 1, the wound length was 4 cm and duration of hospitalization was 2 days. In case 2, the wound length was only 2.5 cm, and the duration of hospitalization was only 1 day.
Isolation and characterization of a novel H9N2 influenza virus in Korean native chicken farm.

<P>An outbreak of avian influenza, caused by an H9N2 low-pathogenic avian influenza virus (AIV), occurred in a chicken farm and caused severe economic losses due to mortality and diarrhea. AIV was isolated and identified in a sample from an affected native Korean chicken. Genetic analysis of the isolate revealed a high sequence similarity to genes of novel reassortant H9N2 viruses isolated from slaughterhouses and live bird markets in Korea in 2008 and 2009. Animal challenge studies demonstrated that the replication kinetics and pathogenicity of the isolate were considerably altered due to adaptation in chickens. Vaccine protection studies indicated that commercial vaccine was not able to prevent virus shedding and clinical disease when chickens were challenged with the isolate. These results suggest that the novel H9N2 virus possesses the capacity to replicate efficiently in the respiratory system against vaccination and to cause severe disease in domestic chickens. The results also highlight the importance of appropriate updating of vaccine strains, based on continuous surveillance data, to prevent the possibility of a new H9N2 epidemic in Korea.</P>
