Urachal carcinoma is an uncommon neoplasm associated with a poor prognosis. We have encountered two another cases of urachal adenocarcinoma recently 5 years after our first report. The common sign of urachal cancer was painless hematuria. We diagnosed the specific site of origin preoperatively by means of computerized tomography. One patient was performed partial cystectomy and another was total cystectomy with double barrel ureterocutaneostomy. A brief review of the literature of urachal adenocarcinoma was also made.

Over twenty per cent of adult knees have a synovial plica which always has possibility of changes into pathologic synovial plica symptomes and signs resembling those of other common internal derangement of the knee joint. Especially the young active patient who has a history of trauma to the knee should once be suspected incarcerated synovial plica not only the possibility of internal derangement. Four cases of symptomatic synovial plica experienced by authors are reported with available references.

The adult worm and plerocercoid larva(sparganum) of Diphyllobothrium mansoni and Moniezia expansa employed in this experiment. The adult worms were divided into three portions, i.e. immature, mature and gravid proglottids, and each proglottids were incubated in 50 cc or 250 cc volume of special incubation flasks with incubation medium consisting of 10 cc of 25 cc of Krebs-Ringer phosphate buffer (pH 7.4). The incubation medium was added C(14)-acetate and non-radioactive carrier Na-acetate so as to contain acetate concentration of 50 mg per cent. The worms were allowed to incubate for 5 hours in the Dubnoff metabolic shaking incubator at 38 C. After incubation period, the lactate and pyruvate appearance rate, total CO(2) production tate, the turnover rates were employed as pervious report(Seo et al., 1965). The quantitative analysis of C(14)-acetate utilized by the adult worm and plerocercoid larva of D. mansoni and M. expansa were compared and discussed in this report. According to these data of the experiment, it is impressed that the fatty acid such as acetate may play a role of major part of their metabolism in the adult worm and plerocercoid larva of D. mansoni , whereas minor part of acetate participated in the metabolism by M. expansa.

Chondroblastoma is a rare primary bone tumor which originates from cartilage, and represents approximate 1% af all bone tumor. The chondroblastoma arises most frequently from the epiphysis of the long bones with the humerus being the commonest site. It afflicts usually the young under 25 years with greater incidence in male. As there is no cartilage cell on craniofacial bone which is mainly fromed by intramembranous ossification, the chondroblastoma on the craniofacial bone is extremely rare. But the chondroblastoma recurred frequently in craniofacial bone when the mass is excised incompletely or curretted and, as the tumor has the outstanding ability of local invasiveness, it destructs the adjacent bone. In addition, it is difficult to diagnose differentially from sarcoma or giant cell tumor histopathologically. Due to the entities described above, it is necessary to remove the entire tumor mass as complete as possible, to treat with radiation pre or postoperatively for preventing from recurrence, and to observe for a long time. The chondroblastoma on temporal bone is rare and is difficult to diagnose and treat successfully. So we'd like to present a case of chondroblastoma which was originated from temporal side of TMJ with literatural review.

PURPOSE: Genes involved in liver cancer cell growth have been identified using an antisense library of large circular (LC-) genomic DNA of a recombinant M13 phage. MATERIALS AND METHODS: A subtracted cDNA library was constructed by combining procedures of suppression subtractive hybridization (SSH) and unidirectional cloning of the subtracted cDNA into an M13 phagemid vector. Utilizing the life cycle of M13 bacteriophages, LC-antisense molecules derived from 1, 200 random cDNA clones selected by size were prepared from the culture supernatant of bacterial transformants. The antisense molecules were arrayed for transfection on 96-well plates preseeded with HepG2. RESULTS: When examined for growth inhibition after antisense transfection, 153 out of 1, 200 LC-antisense molecules showed varying degrees of growth inhibitory effect to HepG2 cells. Sequence comparison of the 153 clones identified 58 unique genes. The observations were further extended by other cell-based assays. CONCLUSION: These results suggest that the LC-antisense library offers potential for unique high-throughput screening to find genes involved in a specific biological function, and may prove to be an effective target validation system for gene-based drug discovery.

BACKGROUND: Hepatitis A is an acute infectious disease of the liver caused by the hepatitis A virus (HAV). The purpose of this study was to investigate the HAV vaccination status and related factors among college students. METHODS: The study subjects were 503 students conveniently sampled from C university located in one district of Jeollanamdo. General characteristics and HAV vaccination related factors were collected by a self-reported questionnaire in October 2013. Chi-square tests and multiple logistic regression analyses were used to evaluate related factors with HAV vaccination. RESULTS: Of the 503 subjects without a history of HAV infection, 65 subjects (12.9%) reported that they were vaccinated. In multiple analyses, subjects who have had health screening (adjusted odds ratio, aOR=2.44 and 95% confidence interval, 95% CI=1.26-4.73) and those who were aware of HAV infection (aOR=6.00, 95% CI=1.81-19.91) or who perceived the benefits of HAV vaccine (aOR=2.05, 95% CI=1.07-3.93) were more likely to be vaccinated than those not involved in these factors. With regard to intention for HAV vaccine, 314 subjects (71.9%) reported that they have the intention to be vaccinated against HAV. In multiple analyses, higher grade level, high monthly allowance, awareness of HAV vaccine, perceived susceptibility of HAV, perceived seriousness of HAV and perceived benefits of HAV vaccine were significantly associated with the intention for HAV vaccination. CONCLUSIONS: The vaccination rate for HAV was found to be low in our sample of college students. To reduce health risks related with HAV, prevention efforts should consider these results.

The term "Milk of calcium" has been borrowed from a somewhat similar condition encountered in the gallbladder. The coexistence of stone in a caliceal diverticulum is well known but milk-of-calcium is unusual in this structure. Recently we experienced a case of milk-of-calcium in a pyelocaliceal diverticulum in a 44 year old man, so we report this case with a brief review of the literature.
