Use of recombinant tissue plasminogen activator (rt-PA) for the treatment of acute cerebral infarction secondary to aortic dissection is challenging because of a narrow time window and potential life-threatening complications. An 80-year-old woman with right middle cerebral artery infarction was treated with rt-PA. Although she had no history, symptoms, or sign of aortic dissection, carotid CT angiography revealed aortic arch dissection. Mediastinal widening, which did not show on initial chest X-ray, developed on follow-up chest X-ray. This observation indicates that physicians should monitor patient symptoms for signs of aortic dissection during thrombolysis and perform chest X-ray or carotid angiography immediately after thrombolysis even if the patient has no symptoms or signs of aortic dissection on onset of acute cerebral infarction.

Insulinoma with hyperproinsulinemia and normal serum insulin level is a rare disease. Because of the neuroglycopenic symptoms, the initial diagnosis tends to be made as epilepsy or as psychosis. A 43-year-old man was admitted to our hospital because of recurrent confusional episodes. Symptoms are intermittent and consist of staring, confusion, amnesia, and bizarre behavior. Vital signs during the episode were normal but the serum glucose level was 27 mg/dl. The serum level of insulin during the episode was lower than normal and those of proinsulin and growth hormone were higher than normal. Solitary pancreatic mass was found by abdominal CT, measuring 15 mm in diameter. Pathologic evaluation showed islet cell tumor. This suggests that the serum level of proinsulin should be checked when insulinoma with neuroglycopenic symptom is suspected.

Sulfasalazine, one of disease modifying anti-rheumatic drugs, is widely used in various rheumatic diseases. Very rarely, sulfasalazine causes drug-associated hypersensitivity syndrome that resembles infectious mononucleosis. Clinical signs include fever, lymphadenopathy, maculopapular skin rash and multivisceral involvement which appear 2 to 5 weeks after administration of drug. Atypical lymphocytosis, liver dysfunction and splenomegaly are also frequently observed. Severe infectious mononucleosis-like syndrome in sulfasalazine treated patients can be caused by reactivation of viruses such as human herpes virus-6, that often result in hypersensitivity syndrome. We report a case of patient who developed infectious mononucleosis-like syndrome after administration of sulfasalazine for the treatment of rheumatoid arthritis. This case warrents careful observation for infectious mononucleosis-like syndrome after sulfasalazine treatment.

OBJECTIVE: Cell therapy has been extensively studied as a gene complementation approach in muscular dystrophy including Duchenne muscular dystrophy (DMD), and adipose tissue has recently been identified as a uniquely abundant and adequately accessible source of pluripotent cells. In the present work, we investigated myogenic potentials of adipose-derived stem cells (ADSCs) depending on culture media and isolation with using surface markers. METHOD: Human ADSCs were obtained by liposuction and cultured in two different media; control and myogenic media. In addition we attempted to isolate ADSCs by utilizing surface markers: CD45 and CD133. The following observations were made to evaluate myogenic differentiation as the expression of myogenic regulatory factors (MyoD, Myf-5 and Myf-6) and desmin by RT-PCR and immunoflurescence study. RESULTS: Conversion of ADSCs to myogenic phenotype was observed by indirect immunoflurescence study of MyoD and Myf-5 in regardless of media type and isolation method. In addition mRNA of MyoD and Myf-5 were positive in both culture media, and there were no differences of MyoD and Myf-5 responses between CD45- and CD45-CD133-ADSCs. However, secondary myogenic regulatory factor (Myf-6) was not expressed constantly, and desmin were negative in all cultural condition. CONCLUSION: Our findings suggest that human ADSCs might have myogenic potentials. However, further studies are needed to express the secondary myogenic regulatory factors and proteins in myoblasts.

OBJECTIVES: To investigate the effect of LH receptor in folliculogenesis, we confirm the expression level of LH receptor (LH-R) mRNA in human granulosa cells (GCs) and its expression levels were analyzed by comparison to embryo developmental rate and pregnancy rate. MATERIALS AND METHODS: GCs were obtained at the time of oocyte retrieval from the patients undergoing IVF-ET program. The patients were divided into two groups: Group I (n=20) is poor responder (retrieved oocyte(s)< or =3ea), Group II (n=80) is normal responder (retrieved oocytes>3ea). After the extraction of total RNA, semiquantitative RT-PCR was performed and the expression level of LH-R mRNA was normalized by beta-actin. Statistical analysis was performed by using Chi(2) test, Student's t-test and Pearson correlation. RESULTS: In Group II, the relative values of LH-R mRNA (0.680 vs. 0.463, p<0.005) and pregnancy rate (54.7% vs. 23.1%, p<0.05) were significantly higher than in Group I. Number of retrieved oocyte(s) was gradually increased when the expression of LH-R mRNA was increased (p<0.05). But the quality of retrieved oocyte and transferred embryo were not related with the expression of LH-R mRNA. When the pregnancy rate was compared with FSH only group and FSH combined with hMG group in the ovarian stimulation protocol, FSH combined with hMG group was significantly higher than FSH only group in Group I (37.5% vs. 0%), and the expression of LH-R mRNA was significantly higher in hMG combined group than FSH only group (p<0.05). CONCLUSION: Expression level of LH-R mRNA has important role in ovarian function related with the response to gonadotrophin in human folliculogenesis. Furthermore these data might provide the evidence that additional use of hMG is helpful to poor responders.

Most osteosarcomas arise spontaneously, but rarely they may be secondary to other benign osseous conditions and may occur following irradiation. Postradiation sarcoma of bone is approximately 5.5 percent of all osteogenic sarcoma. Diagnosis is possible when a sarcoma arising after long latent period(more than 3 years) in irradiated bone and the bone is normal or benign osseous lesion at the time of irradiation. The spontaneously arising osteogenic sarcomas are distribute mainly in the knee region, but postradiation sarcoma arise in any bones, such as long bone of the extremity, pelvic bone, vertebra, craniofacial bone and shoulder girdle bone. Recently we experienced a case of postradiation osteosarcoma of the pelvic bone who received radiation therapy for carcinoma of the uterine cervix 20 years ago.
