Sphenoid sinus aspergillosis is notorious for its serious complications, such as permanent cranial nerve deficits and possible death. The most common associated symptoms are headache, followed by visual changes, and cranial nerve palsies. Because of an insidious onset, frequently resulting in missed and delayed diagnosis, sphenoid sinus aspergillosis is a potentially lethal medical condition. We report a case of visual loss secondary to isolated sphenoid sinus aspergillosis. A 69-year-old man presented to our hospital with the complaint of headache. The headache started one year previously and was described as severe dull pain localized bilaterally to the temporo-orbital region. The patient took daily NSAIDs for the pain. The neurological examination was normal. The MRI of the brain showed a left sphenoid sinusitis. A transnasal endoscopic superior meatal sphenoidotomy was performed. Aspergillosis was confirmed after a surgical biopsy was obtained. The patient was discharged from hospital without antifungal therapy. One month later, the patient complained of headache and loss of vision bilaterally. The orbital MRI showed a left cavernous sinus and bilateral optic nerve invasion. The loss of visions was permanent. In our case, the diagnosis was delayed; antifungal agents were not administered after surgery and the patient lost his vision as a result. Therefore, early diagnosis and proper treatment are important. Although the treatment of an invasive type of aspergillus has not been established, surgical removal of a nidus and aggressive antifungal therapy are recommended.

In this study, we are to produce the single chain variable fragment (scFv) antibodies against surface protein of hepatitis B virus (HBV) using antibody phage display technique. Balb/c mice were immunized with preS1 and cDNAs of heavy and light chains of splenic B cells from immunized mice were prepared using RT-PCR. Two cDNAs were linked with (64S) linker DNA under recombination PCR to produce single chain Fv DNA. After digestion of scFv DNA with Sp 1 and Not 1, the digested DNA was ligated into pCANTAB 5E and electroporated into E. coli XL1-Blue to prepare scFv-library. The size of library was 1 * 10' pfu/ml. Phage antibodies (phabs) against preS1 were rescued with M13K07 helper phages, and preS1-binders were selected through 3 times of panning using 96 well microtitre plates. Phage antibody clones were assayed directly for the ability to bind preS1 by ELISA. And then 7 phage antibody clones had high ELISA signals against preS1. Phabs from preS1-specific pMsc-17 had the strongest ELISA signal to preS1. Phabs from pMsc-17 were used for Western blot to preS1 and the results revealed that it was specific to preS1. To prepare the soluble scFv antibody, phabs from pMsc-17 were transfected into non-suppressor E. coli HB2151, and grown under 1 mM IPTG. Soluble scFv antibody was mainly accumulated in the periplasmic space, but small amount of antibody was secreted into culture media.

Human monoclonal antibodies have considerable potential in the prophylaxis and treatment of viral disease. By cloning human Ig gene segments from the B cells of volunteer into pComb3 phagemid vector, antibody library was created of filamentous phage particles displaying Fab fragments on their surface after being rescued with M13KO7 helper phages. The size of library was 7x10' pfu. Phage antibodies (phabs) were panned against biotinylated preS1 using streptavidine coated Dynabead. The soluble Fab antibodies were prepared from phagemid colonies and assayed directly for the ability to bind preS1 by ELISA. And then 3DW and SGW specific to preS1 which have both heavy and light chain to form Fab fragment, were selected. The soluble Fab antibody from 3DW was expressed highly at the concentration of 0.1 - 1.0 mM of IPTG, and 5 hours postinduction. The soluble antibodies from 3DW and SGW showed their relative affinities of 2x10' M ', and Sx10 M ', respectively, and the specificities to preS1 on ELISA. Our results suggest that antibody phage display library is very useful method to generate the human monoclonal antibody and that the human Fab monoclonal antibodies specific to preS1 selected in this study open the way to treat hepatitis B as a component of passive irnmunotherapeutics.

The occurrence of heterotopic tissue in the large intestine is unusual. The most common heterotopic tissue type described is gastric-type mucosa. On the other hand, heterotopic salivary gland tissue in the large intestine is extremely rare. To the best of the authors' knowledge, only five cases of heterotopic salivary gland in the large intestine have been reported, and all cases arose in the left colon. One out of five cases arose in the sigmoid colon, and the four other cases were found in the rectum-anal canal region. Endoscopically, they usually appeared as a polyp. The presentation of the patients was rectal bleeding or asymptomatic. Heterotopic salivary gland tissue in the colon has not been reported in Korea. This paper reports a case of heterotopic salivary gland tissue at the hepatic flexure of the colon and reviews the literature on similar cases. A 55-year-old male underwent large bowel endoscopy for colorectal carcinoma screening. The colonoscopy revealed five polyps. A sessile polyp at the hepatic flexure, 0.6 cm in size, was resected in a piecemeal manner. The histopathologic findings revealed a salivary gland with mixed mucinous-serous features and ducts. The other four polyps all were diagnosed as tubular adenoma with low-grade dysplasia.

BACKGROUND AND PURPOSE: This study was undertaken to compare the sensitivity of the Repetitive Nerve Stimulation Test (RNST) between the upper and lower extremity muscles in myasthenia gravis(MG) patients. MATERIALS AND METHODS: The study population consisted of 20 normal persons(control group) and 10 MG patients(MG group). Using Stalberg's method. RNST was systemically performed in orbicularis oculi muscle. upper extremity muscles(flexor carpi ulnaris. abductor digiti quinti), and lower extremity muscles(tibialis anterior. extensor digitorum brevis. vastus medialis). RESULTS: There were statistical differences of decremental response(mean+/-SD) in orbicularis oculi and upper extremity muscles between the control and MG groups(p<0.05 or p<0.01). However, there was no statistical difference of decremental response(mean+/-SD) to RNST in lower extremity muscles between the control and MG groups. There were highersensitivity in orbicularis oculi and upper extremity muscles than lower extremity muscles. Although positive reponse were detected in the lower extremity muscles, the positive response rates of lower extremity muscles were lower than o.oculi and upper extremity muscles. CONCLUSIONS: When the response rates of RNST in facial and upper extremity muscles are normal, may not be required RNST in lower extremity muscles.

Pertutaueous transluminal angioplasty is the treatment of choice for renovascular hypertension in cases due to the renal vascular occlusion which is not severe enough to pass dilatation catheter. The advantages of percutaneous transluminal angioplasty are the use of local anesthesia, its noninvasiveness without surgical risk, feasibility of repetition and shorter hospital days compared with surgical methods. We are presenting a case of renovascular hypertension due to atherosclerosis cured by percutaneous transluminal angioplasty with the review of literatures.
