PURPOSE: Prostatic tumor induced gene-1 (PTI-1) is a mutated human EF-la and putative prostatic carcinoma tumor-inducing oncogene, that is differently expressed in prostatic cancer and benign prostatic hyperplasia. And, it is more sensitive marker than prostate- specific antigen (PSA) for detecting human prostate cancer in the bloodstream. This study invastigated the expression of PTI-1 in paraffin embedded tissue of prostatic carcinoma, prostatic intraepithelial neoplasia, and benign prostatic hyperplasia using in situ PCR. MATERIALS AND METHODS: we evaluated expression of PTI-1 in prostatic carcinoma with prostatic intraepithelial neoplasia (PIN) of 32 cases, benign hyperplasia of 20 cases, high grade transitional cell carcinoma of 10 cases and colon cancer of 10 cases for control group. Also, the immunohistochemical staining for PSA was performed to comparison with clinical value of PSA. RESULTS: The serum level of PSA was closely related to stage and Gleason score (p < 0.05). However, the results of immunohistochemical stains were variable to stage and Gleason score. PTI-1 using in situ PCR expressed in 50% of prostatic carcinoma, 41% of prostatic intraepithelial neoplasia, 10% of benign hyperplasia and colon cancer (p < 0.05). No expression is observed in transitional cell carcinoma. In prostatic carcinoma, PTI-1 expressed in 43.8% (7/16) of stage II, 50.0% (5/10) of stage III, and 66.7% (4/6) of stage IV (p<0.05). In PIN, expression of PTI-1 was similar to prostatic carcinoma (p<0.05). CONCLUSION: PTI-1 represented a relatively sensitive marker for prostatic carcinoma and PIN, indicator of prostatic carcinoma progression.

The dual muscle flap (Latissimus dorsi+ Serratus anterior muscle) based on the thoraco-dorsal vascular system for limb reconstruction has been infrequently reported. We have used this flap as a free flap for limb reconstruction in four patients (3 cases in lower linb, 1 in upper limb). A Latissmusi dorsi muscle or musculocutaneous flap and Serratus anterior muscle flap were used and all cases healed satisfactorily. The indications for this flap are to resurface two separate defects simultaneously or to resurface very large defects. It has the advantage of requiring anastomosis of one vascular pedicle only. This flap is particularly suitable for resurfacing defects wider than their length, in relation to the long axis of the limb.

BACKGROUND: Herpes simplex virus (HSV) is associated with a insignificant skin lesion, keratitis, encephalitis, congenital infection, sexually transmitted disease, or cervix cancer. There are two types of serogroup, HSV-1 and HSV-2. HSV-1 makes the lesion mainly on the above-waist area and HSV-2 makes the lesion mainly on the below-waist area. To diagnose the HSV infection, immunological or cultural methods usually have been used until now. But they are not satisfactory in terms of sensitivity, specificity, and ease of application. Recently the polymerase chain reaction (PCR) was developed. Because of the exponential nature of the amplification, this method can detect extremely small amount of DNA. We compared nested PCR with cultural method for HSV detection. METHODS: We obtained 61 specimens from the lesions of oral mucosa, face, and genital area. Samples were inoculated into the monolayer from the African green monkey kidney cell(Vero). When the slide showed cytopathic effect(CPE), HSV infection was confirmed, After extracting DNA from 61 samples, we amplified HSV DNA using nested PCR with the primers against the gene encoding glycoprotein (gD) of HSV-1 and HSV-2. RESULTS: We found 632 bp band after the 1st PCR round and 271 bp band after the 2nd PCR round with HSV-1 specific primers. HSV-2 revealed 428 bp band after the 1st PCR round and 231 bp band after the 2nd PCR round. Nested PCR showed analytical sensitivity at 10(-9) g of DNA in HSV-1 and 10(-10) g of DNA in HSV-2. Viral culture was positive in 36%, nested PCR detected HSV DNA sequence in 54% of samples. Nested PCR typed HSV, HSV-1 in 67%, HSV-2 in 39%, and mixed type in 6% of PCR-positive samples. All isolates from above-waist area were HSV-1. Seventy seven percent of 13 isolates from below-waist area were HSV-2 and 38% were HSV-1. CONCLUSIONS: Nested PCR offers a rapid, simple, and sensitive test for HSV infections of skin and mucosa.

Abdominal cystic lymphangioma is a rare congenital malformation of lymphatics. Prognosis is excellent with exact diagnosis and complete surgical excision. The aughors analysed 10 US scans and 9 CT scans of surgically proven cystic lymphangiom for the last 5 years. US scan showed it as a septated cystic mass and 2 cases showed fluid-fluid level. CT scan showed a huge unilocular or multilocular density mass with uniformly thickened septae. A huge unilocular or multilocular cystic mass with uniformly thickened septae could suggest cystic lymphangioma would be differentiated from the other cystic masse.

N,N-Diethylnitrosamine (DEN) has been proved to have carcinogenic potential in the initiation or promotion stage and the transformed cells proliferate to form preneoplastic nodules which are positive for placental form of glutathione S-transferase (GST-P). E-Cadherin, a member of the cadherin family, is expressed in epithelial cells. To evaluate the role of adhesion molecules (E-Cadherin, alpha-catenin, and beta-catenin), which have not been well understood in carcinogenesis, we investigated the changes of E-cadherin, alpha-Catenin and beta-Catenins by immunohistochemistry and immunoblotting in DEN-induced hepatocarcinogenesis of rat liver. In addition, the sequential analysis of histopathology and the expression of GST-P were also examined. Immunoreactive areas for GST-P were gradually increased from early period of carcinogenesis and strong GST-P positive foci were noted in various lesions, especially in the clear cell and eosinophilic cell nodules. Immunohistochemically, the E-Cadherin expression was increased in DEN-treated preneoplastic nodules in 4 and 10 weeks and hepatocellular carcinomas displayed relatively reduced expression compared with the hyperplastic nodules. But alpha- and beta-catenin expression was increased in hyperplastic nodules and hepatocellular carcinomas. Immunoblotting studies revealed that the level of alpha-catenin (cytosol and membranous fraction) was overexpressed in hyperplastic nodules as well as hepatocellular carcinomas, which showed markedly increased expression. The membranous fraction of beta-catenin was markedly increased in 10 weeks of DEN treatment and slightly reduced in hepatocellular carcinomas. These findings suggest that during DEN-induced hepatocarcinogenesis, the clear cell and eosinophilic cell nodules expressing GST-P in their cytoplasm are early transformed cell nodules. The altered expression of E-Cadherin and catenins is closely related with tumor propagation. Loss or reduced expression of E-cadherin may play a role in the progression of late hyperplastic nodule to hepatocellular carcinoma in DEN-induced rat hepato carcinogenesis.
