Glutathione S-transferase (28GST) with molecular mass of 28 kDa is an antioxidant enzyme abundant in Clonorchis sinensis. In adult C. sinensis, 28GST was localized in tegumental syncytium, cytons, parenchyma, and sperm tails examined by immunoelectron microscopy. C. sinensis 28GST was earlier found to neutralize bioreactive compounds and to be rich in eggs. Accordingly, it is suggested that 28GST plays important roles in phase II defense system and physiological roles in worm fecundity of C. sinensis.

In 1974, bipolar endoprosthesis was first introduced by Bateman & Giliberty. It has theoretical advantages including minimizing acetabular wear, possible reduction of incidence of stem loosening, lessening of dislocation and easy revision procedure. Various methods for the treatment of fracture of the femur neck have been developed & performed, but it is still called “the unsolved fracture” in certain situation. But the role of it as primary treatment of fracture of the femur neck continues to be controversial. Current clinical results encourage its continued use and expansion of indication. Authors reviewed and analysed 21 cases of bicentric endoprosthesis and 1 case of Giliberty endoprosthesis those have been operated at the Department of Orthopaedic Surgery, National Medical Center from 1981 to 1983. Following results were obtained, l. According to disorder distribution, 14 cases were neglected fracture of femur neck, 2 old fracture, 1 idiopathic femoral head necrosis and 2 avascular necrosis & 1 non-union complicated by femoral neck fracture. 2. Among 20 cases, 8 cases were operated within 1/2 1 month after injury and 6 cases within 1 3months 3. Harris lateral appmach was used in 16 cases (80%) and Modified Gibson approach in 4 cases (20%). There were no significant differences in morbidity during operation and postoperative complication. 4. We used femoral stems those head diameter was 22 and 32mm(Charnley & Miiller type) and head pieces those diameter was 48-51 mm in male and 44–48 mm in Ifemale. 5. 3 cases were stiff in inner bearing without acetabular erosion. 6. In 6 cases more than 2 years followup 1 degree CE angle of Wiberg was increased in 2 cases of youngage respectively without associated hip joint pain. 7. Although inclination of head piece was vertical in 8 cases, fracture and dislocation were not found. 8. The circumference of head piece and opposite femoral head was measured and compared. There were 12 cases (mean 12.6 mm) that of head piece larger than opposite femoral head and 3 cases smaller than opposite femoral head. 9. There was 4 cases of complication (3 patients) and still no reoperation and revision converted to T.H.R. 10. With regard to average 18 months of follow-up, 7 cases of 81–90 Harris hip-rating score, 6 of 91–100, 4 of 71–80 and 3 of 61–70.

Meningiomas are usually thought of as firm solid tumors and most standard references make no mention of cystic meningiomas. Although several cases of cystic meningioma have been reported in the literature and their neuroradiological features discussed, the rarity of this entity makes its preoperative diagnosis difficult. Recently, the authors encountered a case of cystic meningioma, which was thought as ependymal cyst or infarction, preoperatively. In this report the authors discussed its clinical, neuroradiological and pathological characteristics with brief reviews of the literature.

The clinical observation was made on 174 patients with congestive heart failure among the admitted patients in Chung Ang university hospital between 1971 and July, 1978. The results were summarized as follows: 1. There were 89 females and 85 males and the incidence was the highest in the 6th decade. 2. The common causes of congestive heart failure were hypertensive heart disease 44.8%, valvular heart disease 21.3% and ischemic heart disease 9.2%. 3. The precipitating factors of congesive heart failure were found in 73.6% of cases and the major factors were arrhythmia 25.3% and infection 15.5%. 4. The important symptoms and signs were dyspnea 86.8%, hepatomegaly 53.4%, pulmonary rales 49.4%, cardiac murmur 46%, tachycardia 35.1% cough 35.1% and orthopnea 34.5%. 5. The ECG findings were abnormal in 92.1% of cases and the frequent abnormal findings were inverted or flat T wave 47.3%, atrial fibrillation 40.6% and left ventricular hypertrophy 33.3%. 6. The chest PA on admission revealed abnormalities in 159 cases, including cardiomegaly 74.6%, pulmonary congestion 66.9% and pleural effusion 26.6%. 7. The major abnormalities of laboratory data were proteinuria and the increase of globuline, BUN, TTT, alkaline phosphatase and SGOT.

BACKGROUND: Pathergy, or skin hypersensitivity to needle puncture has been reported as a diagnostic test for Behcets ciisease. But the positivity of pathergy test in recurrent aphthous stomatitis which can be a comporent of Behcets disease is obscure. In recent years it has been noted that the positivity of the test has decreased. It is possible to say that the disposable needles used nowadays are less trauniatic to initiate the reaction than are the nondisposable ones used in the preAIDS ara by some uthors. OBJECTIVE: It is the porpose of this study to clarify the value of pathergy test in differentiating Behcets disease from recurrent aphthous stomatitis and to evaluate the difference of positivity using various kinds of needles, and finally to suggest the most profitable one. METHODS: 34 patients with Behcets disease according to the diagnostic criteria of Shimizu(revisecl) 25 ones in case of applying that of International study group for Behcets disease(ISG) and 21 ones with recurrent aphthous stomatitis, and 25 normal controls were selected. A pathergy test, i.e., intradermal injection of 0.1 ml physiological saline by using 26 gauge & 20 gauge disposable needles and 26 gauge & 20 gauge nondisposable ones were given and the evaluation was made after 24 hours and 48 hours. RESULTS: 1. The positive rates of pathergy test using all kinds of needles in Behcets disease were significantly higher than thoen recurrent aphthous stomatitis and normal controls(p=0.00000-0.03600). The sensitivity were 29.4% 64.7% (Shimizu) and 32.0% 76.0% (ISG), respectively, and the specificity were 91.3%-100.0% for all of them. 2. In Behcets disease, the positive rates of the pathergy test using 26 gauge disposable needles were not significantly different from that of using ZO gauge disposable needles in total and active patients after 24 and 4.3 hours and so were 26 gauge R 20 gauge nondisposable ones(p=0.40134 -0.80603(Shimizu), 0.37551-0.77078(ISG) ). 3. In Behcets disease, the positive rates of pathergy test using 26 gauge nondisposable needles were 59%-68%(Shimiu) and 64% 79% (ISG), which were significantly different, from the test using 20 gauge disposable needles, i.e. 29%-36%(Shimizu), 40%-46%(ISG) in total and active patients(p==0.00753-0.01512) after 24 and 48 hours except for those by the criteria of ISG after 24 hours(p=0.14573-0.15597). CONCLUSION: This study shows that the pathergy test is obviously useful in differentiating Behcets disease from ecurrent aphthous stomatitis and we recommend the intradermal injection of 0.1 ml physiological saline by using 26 gauge nondisposable needle and the evaluation after 48 hours as a standard mithod of pathergy test.

Pressure alopecia can occur after prolonged pressure on the scalp with the head fixed in one position. We have repor ted 5 cases of pressure alopecia, occurring over the contralateral temporoparietal 1 area after tympanomastoidectomy due to chronic ot.itis media. Total times of operations were from 4 hours to 7 hours. Four of the 5 patients experienced scalp pain during the early postoperative period and one of them showed large bulla formation. Loss of hairs followed between the 14th and 36th postoperative day, and new hairs began to grow 2 or 3 months after the operation.

Lichen aureus is a variant of pigmented purpuric lichenoid dermatitis. The skin lesions usually appear asymptomatic rusty, copper, or orange colored roundish lichenoid erythematous-purpuric papules and patches on the lower extremities. Histologically, the epidermis shows minimal changes, with a dense lymphohistiocytic infiltrate observed in the superficial derrnis, typically distributed in a band-like fashion. The typical lesion is a single patch localized on the lower extremity. We report a rare case of segmental lichen aureus localized on the right lower extremity.

Pigmented lesions of palmar and plantar skin may cause diagnostic problems, because some features of benign lesions in these sites may raise the suspicion of melanoma if considered alone. Transepidermal elimlnation is a mechanism by which a substance is eliminated through the epidermis, and it is apt to be confused with a feature of melanoma that tumor cells are located at all layers of the epidermis. We report a case of transepidermal elimination of nevus cells in acral letiginous nevus which needs a differential dignosis of melanoma.
