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.

A monoclonal antibody to PCNA, which can be used on routinely processed tissue, was applied to 25 cases of gastric adenomas and 64 cases of gastric adenocarcinomas in order to diffentiate adenoma and adenocarcinoma and also to evaluate the prognostic value in adenocarcinoma. The results were summerized as follows: The PCNA labelling index was 29.14+/-12.77% in control, 44.09+/-17.11% in adenoma and 80.15+/-10. 69 in adenocarcinoma, resulting in significant increase in adenocarcinoma compared to adenoma. In adenocarcinoma, no significant correlation was observed between PCNA labelling index and histologic grade, and there -was increased tendency of PCNA labelling index in proportion to depth of invasion without statistical significance. The PCNA index was significantly increased in advanced adenocarcinoma compared to early gastric carcinoma, and also in positive nodal metastasis group than in negative group. From above results, the PCNA stain will be able to provide a helpful method for the differential diagnosis between gastric adenoma and adenocarcinoma, and could be a useful prognostic factor in adenocarcinoma if other factors are considered together.

Hepatic fibrosis was induced in Sprague-Dawley rate to evaluate the ultrastructural changes of fat-storing cells (Ito cells). For experimental induction of liver fibrosis, the rats were administered intraperitoneally with 0.5 ml of 50% Ccl4 solution per Kg body weight, twice weekly for 12 weeks. The rats were sacrificed every week. The liver tissues were examined under light and electron microscopes. And the immunohistochemical study of desmin was also performed. The results were summarized as follows: Light microscopic findings: The cellular infiltrations was inflammatory cells and Kupffer cells developed from 1 week after Ccl4 injection, and were the most severe in 4 weeks. The strong immunoreactivity for desmin was also evident in 4 weeks. The centrilobular necrosis and fibrosis developed from 2 weeks after injection, and the necrosis persisted until 8 weeks. The progress of fibrosis was accompanied by decreases in cellular infiltration and reactivity for desmin, and increased gradual nodular formation was also observed. The cirrhosis was developed after 10 weeks. Electron microscopic findings: An increase in number of fat-storing cells was observed from 1 week after injection. Transitional cells characterized by a depletion of lipid droplets and a hypertrophy of the rER appeared after 2 weeks. The number of transitional cells with abundant collagen fibers in the extracellular spaces increased in 4 weeks. With progression of fibrosis the number of fat-strong cells decreased and proliferating fibroblasts with dilated rER were observed. According to these results it was revealed that there was an apparent transition from fatstrong cells to transitional cells and to fibroblasts. These cells had a few similar characteristics and may belong to the same cell population. Thus it was suggested that fatstrong cells might play an important role in hepatic fibrosis.

It has suggested that a significant proportion of intraepithelial lesion of the cervix may be related to the influence of human papillomaviurs (HPV). Its etiological relation with cervical intraepithelial neoplasia (CIN) and cervical squamous cell carcinoma has recently been proposed. The 131 cases of CIN and 6 condyloma acuminata were stained by immunoperoxidase technique for HPV anigen. The results are as follows: The 18 cases (13.1%) exhibited positive staining, localized in nuclei of koilocytotic cells confined to superficial and intermediate layer of epithelium. HPV antigen was found in 1 case (16.7) of 6 condyloma acuminata, 4 cases (12.5%) of 32 mild dysplasia, 3 cases (13.6%) of 22 moderate dysplasia, 2 cases (14.3%) of 14 severe dysplasia and 8 cases (12.7%) of 63 carcinoma in situ. In the positive cases of mild and moderate dysplasia, HPV antigen was localized directly within the lesion, while those cases of severe dysplaia and carcinoma in situ contained positive cells in areas of mild or moderate dysplasia adjacent to the lesion. Of three distinct morphologic patterns, flat type was most common and papillary type was least. Histologically condylomatous lesions were present in 67 cases (51.1%) out of 131 cases of CIN. The histological and cytological feature encountered most frequently was koilocytotic arypia. Other main histological features are bi- or multinucleation, exocytosis of inflammatory cells, acanthosis, mitotic figures, dyskeratosis and epithelial pearl. On the cervical smear, the evidence of condyloma was proved in 50.0%. Cytologically in the condyloma with high degree of CIN, the nuclear atypia was so prominent that the differentiation from dysplasia or carcinoma in situ was very difficult, although the chromatin appeared somewhat smudged. The mean age of 18 cases was 42.4 years which is older than previous study. The results of this study provide common association with HPV and CIN and add great weight to the suggestion that the infection with HPV plays an important part in genesis of cervical cancer.

The association rate of antibody with antigen has been reported to be greatly increased by lowering ionic strength. Low-ionic strength salt solution(LISS) method has been used for the detection of various alloantibodies. To investigate the sensitivity of LISS in indirect antiglobulin test, a comparison study of LISS with saline and albumin methods was conducted. A total of 32 patients' samples requested for indirect antiglobulin test were evaluated. Out of 32 patients with clinical immune hemolytic anemia, 11(34.3%) were positive in 37 degrees C saline antiglobulin test, 18(56.2%) in albumin antiglobulin test, 23(71.8%) in LISS antiglobulin test respectively. These results were statistically analyzed using non parametric Page's test for ordered alternatives. LISS method is more sensitive than 37 degrees C saline method or albumin method significantly (p<0.01).

The cryopathic hemolytic anemia is an autoimmune hemolytic anemia induced by cold antibody. Authors report a case of cryopathic hemolytic anemia confirmed by immunohematologic examination. A 22-year-old man was admitted at Kyung Hee Medical Center in March, 1994, with a past history of Kleinerfelter's syndrome and complained jaundice as well as dizziness. Direct antiglobulin test using polyvalent and anti-C3d monovalent antisera was positive, but was negative against anti-IgG, anti-IgA, and anti-IgM monovalent antisera. Cold agglutinin titer was as high as 1:1024 at 4 degrees C and anti-I specificity was confirmed by using cord bloods. The patient was not improved despite transfusion of washed red cells and administration of prednisolone, and on 16th day of hospitalization he manifested sudden episode of headache and loss of conscioussness, soon followed by death.

We analysed the results of total knee replacement arthroplasty without patellar resurfacing in 20 patients(28 knees) retrospectively. The patella was not resurfaced when it maintained relatively healthy cartilage in osteoarthritis or the patella was too thin to be replaced in rheumatoid arthritis. The diagnoses were osteoarthritis in 11 and rheumatoid arthritis in 17 cases. The follow up period was 30.3 months in average(12-70 months). A lateral retinacular release was performed in 22 knees(78.6%). The mean knee society score improved from 45.4 preoperatively to 84.1 postoperatively and the functional score improved from 21.4 preoperatively to 63.3 postoperatively. The modified Kujala score was 43.2 points in osteoarthritis and 43.6 points in rheumatoid arthritis. We conclude the total knee replacement arthroplasty without patellar resurfacing shows good results, without high risk of postoperative peripatellar complication.
