2.A Study on Cell Mekiated Immunity in Parients with Psoriasis.
Korean Journal of Dermatology 1981;19(4):397-403
Psoriasis is common cutaneous disorder involving 0.1~3% Of the general population and is characterized by its marked chronicity and recurrence. A variety of factors, rarging from heredity, environment to abnormal cytodynamics and biochemical perturbation have been implicated but never proved as causative. In recent years, many studies on psoriasis have been reported, showing the presence of certain immunologic abnormalities in patients with psoriasis, and some authors postulated that these immunologic abnormalities, particularly in cell mediated immunity, may play a key role in the pathogenesis of psoriasis. This study was undertaken to evaluate cell mediated immune status of patients with paoriasis using several immunologic parameters. A total of 70 patients (35 were male and 35 were female) between the ages of l:l and 70 years entered this study at the Department of Dermatology of Seoul National University Hospital from January 1980 through September 1980. Peripheral blood T lymphocytes(early and total) were enumerated by E-rosette technique in 55 patients. Delayed cutaneous hypersensitivity reaction was measured in 3O patients using intradermal candidin, trichophytinand PPD. Active sensitization with DNCB was performed in 30 patients.

anserine folliculosis (Padilha-Gonqalves, 1977) is a skin disease occurring on the limited areas of the skin receiving prolonged friction and/or pressure by the other part(s) of the naked skin of the patient. Padilha-Goncalves named traumatic anserine folliculosis by stressing the etiologic factor, the pressure and friction, the goose skin appearance and the follicular nature of the basic skin lesions. A 7-year-old girl developed typical features of traumatic anserine folliculosis on the chin who had the habit of resting the chin on the right knee for 5 years while painting.

For parthenogenetic activation as a model system of nuclear transfer, microinjection and electroporation as activation treatments in bovine metaphase II oocytes were administered to each of three groups as follows: control group (treatments with Ca2+, Mg2+ -free PBS+100 micro M EGTA), IP3 group (control+25 micro M IP3) and IP3+ ryanodine group (control+25 micro M IP3+10 mM ryanodine). In experiments using microinjection, no significant differences were observed between any of the developmental stages of the electroporation experiment. For electroporation, cleavage rates were significantly higher in the IP3+ryanodine group than in the IP3 or control group (85.6% vs 73.7% or 67.6%, respectively). In the subsequent stages of embryonic development, such as morula and blastocyst formation, the IP3 and ryanodine group exhibited significantly higher rates of morula fomation than the IP3 or control groups (40.6% vs 24.2% or 16.7%, respectively). Similarly, the rate of blastocyst formation in the IP3+ryanodine group was significantly higher than the control group (16.3% vs 6.9%) but did not differ significantly from the IP3 group (16.3% vs 9.5%). In nuclear transfer, activation was performed at 30 hpm by microinjection and elecroporation with 25 micro M IP3+ 10 mM ryanodine followed by 6-DMAP treatment. No significant differences were observed at any stage of embryonic development and none of the embryos activated by electroporation reached either the morula or blastocyst stage. However, 3.8% and 1.9% of embryos activated by microinjection sucessfully developed to the morula and blastocyst stages, respectively. In conclusion, activation treatments using IP3 and ryanodine are able to support the development of bovine parthenogenetic and reconstructed embryos.

Bone scan measuring bone metastasis were analysed in fifty five patients diagnosed as malignant tumor, seven were primary bone tumor and forty eight were metastatic tumor, who treated in Kyung Hee Hospital from March 1981 to January 1982. The results were as follows: l. In 55 patients, positive bone scan were found in 76.4% of the patients and positive X-ray were found in 56.4%. 2. 7 patients with primary bone tumor showed all positive bone scan, 45 patients with metastatic tumor showed positive bone in 72.9%. 3. Among the patients with metastatic tumor who no clinical symptoms, positive bone scan were found in 59.3% and positive X-ray in 26%. 4. Most common metastatic site was femur in primary bone tumor and vertebra in metastatic tumor. 5. In 48 patients of metastatic tumor, positive bone scan within negative X-ray were found in 56%, negative bone scan within positve X-ray were found in 5%. 6 The lesions showed clod area on bone scan were considered of positive finding as compared with clinical symptom and X-ray finding.

Pagets disease has been well known disease in western countries, but it is extremely rare in orient and no case has been reported in Korea yet. It is a chronic osseous disease affecting middle and late life, characterized by progressive skeletal deformities which consist of excessive resorption and abnormal regeneration. We experienced a case of Paget's disease in a 57-year old man with involvement of pelvis, femur and skull, and confirmed with open biopsy.

10.A Survey for Methicillin

Nine strains (6%) were confirmed as resistant (MIC=20ug/ml) to methicillin (MT) among 150 isolates of staphylococcus aureus. These MT-resistant staphylococcus aureus (MRSA) strains were also turned out to be more less resistant to other antibiotics tested, such as penicillin, chloramphenicol, tetracycline, and gentamicin except for cephaloridine. It was noteworthy, however, that strain MRSA 5 showed a relatively susceptible attitude toward most of the antibiotics tested, while being extremely resistant to MT only. Salt (NaC1) containing (5-3%) media did not have any significant effect on the degree of MT-resistance of MRSA strains. There was, however, such a tendency as that by the addition of salt the degree of MT-resistance was lowered in the highly MT-resistant strains while enhanced in MT-susceptible ones. It was confirmed that penicillinase did not have any effect on the MT-resistance while most of the penicillin- resistant strains produced the enzyme.
