1.Cutaneous Metastasis from Prostatic Carcinoma.
Annals of Dermatology 2000;12(2):114-116
Prostatic carcinoma is one of the most common malignancies in males of western countries but it is a rare malignancy in Korea. If it occurs, it commonly metastasizes to other organs. In-spite of its high incidence of distant metastasis, the cutaneous metastasis of the prostatic carcinoma is very rare and seems to have a poor prognosis. A 67-year-old man presented multiple nontender nodules on the skin of the right thigh and had episodes of multiple metastases from prostatic carcinoma to the lungs and bones. Histopathologic findings of the skin showed atypical cells infiltration at the dermis. Immunohistochemical staining for prostate specific antigen showed a positive reaction, therefore, we reached the diagnosis of cutaneous metastasis from prostatic carcinoma.

Several measurements were performed about 105 cases of normal stress A-P arthrographic findings in adult knee including discoid without tearing or osteoarthritis, those were selected from 166 cases examined arthrographicaliy under same technical condition due to suspicious internal derangement of the knee from October 1976 to March 1980. After stastistical analysis and comparative study about chondrai thickness, chondral index, meniscal size, meniscal index, intermeniscal distance, type of meniscus, communication between knee and proximal tibiofibular joint, following results were obtained. 1. Chondral thickness of normal articular cartilage was not related to joint size, but almost same value individually. Mean chondral thickness In P and P points was 2.90±0.63mm, 2.90±0.62mm, 2.93±0.64mm, 2.92±0.65mm in lateral, medial femoral condyle and lateral, medial tibial condyle in order. Age change was not seen statistically. 2. The size of meniscus was correlated nearly proportional with that of the joint. Mean lateral meniscus size (transverse meniscal length × meniscal thickness) was 12.55±2.50mm × 6.53±0.7mm in male and 10.13±2.25mm × 6.02±0.52mm in female. That of medial meniscus was 9.79+1.54mm × 5.85+ 0.45mm in male, and 7.72±1.64mm × 5.36±0.92mm in female. Age change was not seen statistically either. 3. Mean intermeniscal distance was 60.21x2.74mm in male, 53.34±3.31mm in female and occupied 83% in male, 82% in female of joint size each other. 4. In types of meniscus, normal type was 8.10%, infantile type dlscoid 12.4%, intermediate type 2.9%, primitive type 3.7% each other. 5. Communications between knee joint and proximal tibiofibular joint were seen in 24%.

Mobility shifts in non-denatured gel electrophoresis of PCR-amplified Rif' region in each of fifteen different mutants of M. tuberculosis were discerned by single strand conformation polymorphism (SSCP) analysis. The findings of mobility differences between rifampin-resistant and susceptible strains showed an excellent agreement with data obtained by traditional susceptibility test. SSCP-PCR seemed to replace the cultivation method of susceptibility test that was known to be time-consuming, labor wasting, and skeptical in quality control. After screening of rpoB gene mutation by SSCP-PCR, detection of specific sequence changes in the region of rpoB gene was attempted through the procedures of PCR-amplification, cloning of PCR-products using pGEM-T vector and DNA thermocycling sequencing. Fifteen different types of mutations were identified among fifty strains of rifampin-resistant strains while five rifampin-susceptible control strains showed no sequence changes of rpoB gene as well as reference strain H37rv. Most mutation appeared to be a point mutation due to substitution or deletion except seven mutants showing somewhat complex mutation. Each of mut#ated loci inclined to clustering within a region of eighteen amino acids involving eight codons. The most common mutation of Ser425 shared among twenty-nine mutants and followed by eleven mutants of His420. Several mutants alleles identified in this study appeared to be dissimilar to those of previous reports.

Interleukin-6 (IL-6) is introduced as a marker of disease. At present, a variety of method may be used to quantify expression of this protein. Antigen capture-ELISA is a sensitive and accurate quantification method previously used with ovine, rat, and human IL-6 proteins. However, it has never been reported to quantify porcine IL-6 protein using capture ELISA. In this study, we generated and characterized a set of IgY and mono-specific polyclonal antibodies to recombinant porcine IL-6 (rpIL-6), and combining these with a sensitive and specific capture-ELISA for a diagnostic purpose. cDNA encoding the mature protein coding region of porcine IL-6 was cloned and expressed with pQE-30UA expression vector. rpIL-6 was then expressed and purified by using Ni-NTA resin. Protein mass of 24 kDa was found with SDS-PAGE and the identity of the protein was confirmed by Western-blot. Production of polyclonal antibodies against rpIL-6 was performed using the purified rpIL-6 in mice and hens. An antigen capture-ELISA was developed with the antibodies after their extraction. To compare the IL-6 level in the different sanitary state of farms, pig sera were randomly collected and concentration of IL-6 in the sera was measured with the antigen capture-ELISA. The capture-ELISA with the optimal concentration of antibodies, in this study, was able to detect about 10 ng/ml of rpIL-6. IL-6 levels determined with the capture-ELISA in pig sera showed positive correlation with the sanitary states of the farms. These results suggested that the developed antigen capture-ELISA could be a good tool for the screening of microbial infection in pig farms.

Forty cases of infiltrating duct carcinoma of the breast were examined immunohistochemically for expression of TGF-beta and angiogenesis in order to analyze significant correlation with prognostic parameters including tumor size, axillary lymph node metastasis, clinical stage, histologic grade, estrogen receptor and progesterone receptor status. The TGF-beta expression was observed in tumors center and advancing edges of tumors. To determine microvessel density for angiogenesis, we stained endothelial cells for Factor VIII related antigen and counted microvessel within tumor. The results were as follows: 1) The strong immunohistochemical expression of TGF-beta and higher counts of microvessels were observed in advancing edges of tumors (p<0.05). 2) The TGF-beta expression in the advancing edges of tumors was closely related to clinical stage and presence of axillary lymph node metastasis (p<0.05). 3) The mean microvessel counts were significantly higher in tumors from patients with axillary lymph node metastasis and increased with increasing clinical stage (p<0.05). 4) The TGF-beta expression was not related to histologic grade, estrogen receptor and progesterone receptor status(p>0.05). Therefore, the results suggested that the TGF-beta expression and angiogenesis in infiltrating duct carcinoma of the breast may play an important part in prognostic factors, closely related to the lymph node metastasis and clinical stage.
