To search the effective antisense oligonucleotide that inhibit the growth of Herpes simplex virus type 1 (HSV-1), six kinds of phosphorothioate oligodeoxynucleotides (S-ODNs) were synthesized and the antiviral activity was assessed by measuring cytopathic effect in Vero cells infected with HSV-1. Of the three dodecamer S-ODNs, cornplernentary to the translation initiation site of IE2 (AS2) and scrambled S-ODN (AS1) showed more significant antiherpetic activity than AS4 complementary to the IE4. Accordingly, the antiviral effect of dodecamer S-ODN was not specific. In contrast to the no inhibitory effect of sense strand S-ODN of ICP8 (AS6), two S-ODNs complementary to the translation initiation site of ICP8 (AS3) and that of IE1 (AS5) showed potent antiherpetic activity assessed in vitro HSV-1 virus yield assay. Antiherpetic effect of AS3 was decreased in proportion to the addition of AS6. The synthesis of viral protein ICPS and IE1 were inhibited in AS3 and AS5 treated HSV-1 infected Vero cells, respectively. These findings suggest that antiherpetic effect of AS3 is specifically mediated by targeting ICPS. S-ODNs had no effect on Vero cell viability. The data suggest that the 19-mer S-ODNs may be effective in antiviral chemotherapy.

2.Effectiveness of Antifungal Agents.
Korean Journal of Dermatology 1982;20(1):77-81
On strains of dematophytes isolated from superficial fungal infection patients, susceptibility tests were undertaken to topical antifungal agents (econazole, clotrimazole, siccanin, and tolnaftate). Minimal inhibitory concentration of the drugs was cletermined after 4 days incubation at room temperature on Sabourauds dextroes agar. Diverse susceptibility pattern was observed among different fungal species. Minor variability of susceptibilities was noted within the same species except for Trichophyton rubrum to econazole and tolnaftate in which a marked variation of susceptibilities was noted, Among drug tested, tolnaftate showed the most strong antifungal action, and Trichophyton mentagrophytes was the least sensitive species to all drugs. Minimal inhibitory concentration levels of each drug are as follows; clotrimazole was in the range of 2-8 mcg/ml., econazole was in the range of 0.06-2 mcg/rnl., siccanin was in the range of 05-2 mcg/ml., and tolnaftate was in the range of 0.01-0.25 mcg/ml.

Erdheim Chester disease (ECD) is very rare non-Langerhans cell histiocytosis (LCH) which occurs in the skeletal system and multiple organs. As it is progressive, sometimes it causes fatal results. However, it is often misdiagnosed as LCH or multiple bone metastasis and, thus, is very difficult to diagnose. In Korea, only 10 cases were first reported in 1999. In particular, there have been a few orthopedic approaches or reports in English-speaking literatures, and no report has been issued in Korea. The authors performed bone biopsy in patients with knee and lower extremity pain who were referred for the integrated treatment. We attempts to report this diagnosis experience with literature review.

The clinical observations regarding cutaneous manifestations of in-and outpatients with diabetes mellitus was performed in the Diabetic Clinic, Seoul National University Hospital during the period of 11 months from April, 1979 to March, 1980. The number of patients were total 525, 268 in male and 257 in female. The average age of patients was 51. 1 year-old. Results were as follows, 1. In the 525 patients, 270 patients (51. 1%) revealed various cutaneous manifestations. 2. There were statistical significant differences in sex distributions of infection, pruritus, shin spots, rubeosis and bullosis diabeticorum. 3. Systemic complications sush as retinopathy, neuropathy, nephropathy and hypertension were more frequently observed in the patients with skin microangiopathy than with infection or pruritus. 4. There were not any correlations between fasting blood sugar and cutaneous manifestations

Chromomycosis is a chronic localized infection of the cutaneous and subcutaneous tissues and characterized by verrucoid, ulcerated and crusted lesions with sclerotic margins. It histologically show confluent granulomatous nodules containing large giant cells of the foreign body type. The organisms are differ from other yeastform fungi by the characteristic chestnut-brown color and by the septate division. A case of 51 year old woman with chromomycosis at submental area is presented.

Adenoma of the nipple is a benign tumor of the lactiferous ducts of the nipple which frequently causes erosion of the surface. It can clinically mmic Paget's disease and histologically be misdiagnosed as a well-differentiated adenocarcinoma. A 20-year-old woman developed an erythematous oozing patch on the right nipple two years ago, which subsequently developed iiito verrucous surfaccd papules. A biopsy specimen of the lesion showed focal acanthosis of the epidermis. The tumor was composed of fairly well-circumscribed, glandlike structures within the nipple stroma. Ductlike struciures, papillary areas, solid nests of cells and cysts lined by squarnous epithelium, could be seen, Two cell types lining the ducts were recognized; inner columnar cells and peripherally located cuboidal cells. Although simple excision of the adenoma is the treatment of choice, our case was treated successfully by electrucoagulation.

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.

Persistent light reaction, actinic reticuloid, photosensitive eczema are three chronic photodermatoses with a feature of clinical, histological, and photobiologieal characteristics in common. These conditions were given the name of chronic persistent photosensitivity. Chronic persistent photosensitivity with the feature of photosensitive eczema developed in a 68-year-old male patient who had experienced persisited dermatitis. On phototesting the patient showed extremely severe photosensitivity to the short wave UVB. A skin biopsy showed microscopic finding of eczematous dermatitis.

Journal of Korean Society of Pediatric Endocrinology 2004;9(1):66-71
PURPOSE:Varying clinical phenotypes are associated with the chromosome 22q11.2 microdeletion syndrome. The endocrine manifestation are latent or overt hypoparathyroidism, thyroid dysfunction and short stature. This study was undertaken to investigate frequencies of endocrine abnormalities and short stature in patients with the chromosome 22q11.2 microdeletion syndrome. METHODS:Forty three unrelated patients were diagnosed having chromosome 22q11.2 microdeletion syndrome. Chromosomal microdeletion was confirmed by fluorescent in situ hybridation (FISH) with DNA probe (22q11.2 LSI TUPLE1 from Vysis). Serum total calcium and intact parathyroid hormone (PTH) were measured in all patients. Thyroid function tests including free thyroxine(T4), thyroid stimulating hormone (TSH) and thyroid autoantibodies were performed in all patients. Insulin-like growth factor-1 (IGF-1) was measured in 10 patients. Height, weight and body mass index were compared with chronological age in all patients. RESULTS:Seven patients (16%) had an overt hypoparathyroidism, presenting with hypocalcemic tetany. Thirteen patients (31%) showing hypocalcemia with normal PTH were regarded as having latent hypoparathyroidism since their PTH secretion response was blunted. Out of 2 patients with thyroid diseases, one patient had Graves disease and the other had Hashimoto thyroiditis. Five patients (12%) were below the 3rd percentile in height at evaluation. The BMI was below the 5th percentile in 23% of patients. CONCLUSION: Twenty patients (47%) presented with overt and latent hypoparathyroidism. Interestingly, autoimmune thyroid diseases such as Graves disease and Hashimoto thyroiditis were associated in patients with chromosome 22q11.2 microdeletion, indicating predisposition to autoimmune disorders. Therefore, a careful endocrine and growth evaluation is needed in these patients.
