Migration of the fixation device to a part of the body is well known complication of fracture treatment. However, few reports of this complication have appeared in the literature. The present report concerns two instances of the migration of a K-wire and a Steinmann pin from the acromioclavicular joint, respectively, into the neck. It appears that if wires and pins are used for fixation, the lateral ends should be bent to prevent medial migration, and as soon as the desired therapeutic results have been obtained, these must be subsequently removed.

Transient synovitis of the hip in children is a non-specific inflammatory and self-limited condition. It is also the most common cause of painful hip in children under ten years of age. Despite of the benign prognosis, there are many difficulties in distinguishing it from other diseases of the hip joint. It remains a common diagnostic problem for clinician because the clinical symptoms, physical findings, and conventional radiography is not pathognomonic of the condition. The authors paid attention to the increase of effusion in the affected hip and studied the value of the hip ultrasonography in 24 cases of transient synovitis from August 1985 to July 1987. The results are summerized as follows : 1. The ratio of male to female was 7 to 1, average age was 7.9 yrs, average hospitalization period was 4.5 days. 2. In simple X-ray studies, no bony change was detectable except for soft tissue signs in 68% of the cases. 3. Capsule-to-bone distance in sagittal ultrasonographic section revealed abnormal increase in 87.5% of the affected hip. 4. Average capsule-to-bone distance of affected hip joint was 7.50 mm, while that of the normal hip was 4.26 mm. 5. As shown in the above studies, ultrasonography can be considered good noninvasive technique in detection and follow-up of hip effusion. So, it is thought to be a valuable method in the diagnosis of transient synovitis of the hip in children.

22 cases of giant cell tumor of bone treated between 1973 and 1979 have been reviewed after a miaimum follow-up of two years and following results were obtaind. 1. Fourteen cases (63%) were in the third and fourth decade. 2. Fourteen cases (63%) were located around the knee joint. 3. Five (42%) of the twelve tumors treated by curettage and bone graft recurred. Five tumors treated by En bloc resection and two tumors treated by amputation had no recurrences. 4. Five of six recurrences occured within two years after mitial treatment.

When a soft tissue mass in the bony wall of the paranasal sinus is present, it is difficult to make a distinction between tumor and inflammatory mass on CT. Fungal sinusitis may have soft tissue attenuation on the bony wall of the sinus, bony sclerosis, focal bony destruction, and calcific area on CT. This is a report of four proven cases of fungal sinusitis, asperogillosis in 3 cases and mucormycosis in 1 case, All 4 patients had CT and one patient had MRI, On CT, bony sclerosis and destruction were well visualized in all cases. On MRI, mycetoma in the maxillary sinus was hypointense on T1 weighted images and more hypointense on T2 weighted images. Although CT appears to be the best modality for initial examination of the patient with sinusitis, the differentiation of fungal sinusitis from tumor mass or other entity may be better accomplished with MRI.

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.

Electron microscopy (EM) can provide a valuable contribution to light microscopy (LM) in the interpretation of fine needle aspiration cytology (FNAC) specimen, especially in the diagnosis of the tumor. However, considerable care in processing the specimen is mandatory to recover the cells and avoid altering the fine structures. We experienced a case of malignant melanoma in 33-yrs-old female, diagnosed by EM study of FNAC specimen from the axillary mass, who was initially thought as dissem- inated carcinomatosis on LM study. The technique of EM study on FNAC specimen consisted of washing the needle and syringe in 2.5% glutaraldehyde after a rapid stain (Diff-Quik), which was used to obtain a preliminary diagnostic impression and to assure the adequacy of the EM specimen. After centrifugation in the steps of fixation and dehydration, the sediment was made into an epon block and examined. The whole processing time of EM study can be shortened within 7 or 8 hours, and results can be available within 48 to 72 hours. Our experience suggests the EM study on FNAC can be a useful diagnostic method in the diagnosis of difficult FNAC cases.

The second case of this serial reports under the title of unusual cutaneous manifestations of connective tissue diseases is a woman with primary idiopathic dermatomyositis who developed cutaneous ulcerations on her arms and legs, which is thought to b a rare manifestation of adult dermatomyositis. These multiple ulcerations are about bean sized, polymorphous, and grouped on the poikilodermatous lesional skin. In this patient these ulcerative lesions became regressive and healed with disfiguring scars after the activity of the disease has controlled by prednisolone and methotrexate.

Korean Ginseng (Panax C.A. Meyer) has survived empirical efficacy as tonic and geriatric agents for several thousands of years in oriental herbal medicine. But there has been numerous controversial reports about its use in aged hypertensive men due to its allegedly hypertensive effects. Therefore, the author conducted the pharmacological studies of Korean Ginseng extracts on the blood pressure and blood lipid metabolism, during development of hypertension, using SHR(Spontaneously Hypertensive Rat), counterpart model of human essential hypertension. The results obtained were as follows: 1. SHR could be grouped, according to their age, as prehypertensive stage(<6th week after birth), labile hypertensive stage(6th 14th week), early established hypertensive stage(14th-20th week), and late established hypertensive stage(>20th week). 2. Plasma renin activity tended to rise steadily, until established hypertensive stage was reached. Thereafter, plasma renin activity tended to decline. 3. The changes of blood pressure due to Ginseng extract, depended on the amount, route and duration of its administration. Low dose of Ginseng tended to increase blood pressure but high dose of Ginseng tended to decrease blood pressure, until 1 week of intraperitonal administration. But prolonged administration of Ginseng extract beyond 1 week, showed delayed hypertensive effect in the intraperitoneal administration but not in oral administration. 4. SHR seemed to have abnormalities in the lipid metabolism. SHR showed lowered level of serum cholesterol and phospholipid, whereas slightly higher level of triglyceride, and showed lower alpha-lipoprotin fraction but higher pre beta-lipoprotein fraction, as compared with NCR.(=Normal Control Rat). 5. When high fat cholesterol salt diet was fed on, it was possible to indece hyperlidemia and increment of hypertension in SHR. but when high fat cholesterol salt diet and Ginseng extract were fed on concomitantly, Ginseng showed significant inhibiting effect on the development of hyperlidemia and hypertension.
