Central nervous system (CNS) sparganosis is a rare parasitic infestation caused by ingestion of the raw or inadequately cooked snakes or frogs. Sparganum is well known for its ability of migrating though the tissue, therefore, it can cause various neurological symptoms if it involves neurological systems. A 51-year-old male patient visited our department of neurosurgery complaining of the motor weakness and radiating pain on both upper extremities over 4 months. He had a history of ingesting raw snakes untill his late twenties. The magnetic resonance (MR) images of. cervical spine revealed an intramedullary ill-defined enhancing lesion with the aggregated cysts in the upper cervical spinal cord. Under presumptive diagnosis of sparganosis, we took brain MR image. The brain MR images revealed the signal change in right fronto-temporallobe suggesting the trajectory of parasitic migration via ventricular systems. He underwent a midline myelotomy and granuloma removal followed by the posterior laminoplasty. Pathologic findings showed inflammatory changes and necrosis with keratinized tissue suggesting the CNS sparganosis. We report an uncommon case of CNS sparganosis migrated from the brain to the spinal cord with literature review.

Although the mechanism of hemifacial spasm (HFS) is not yet well established, vascular compression of the facial nerve root exit zone and hyperexcitability of the facial nucleus have been suggested. We report a case of HFS in the setting of coinciding intracranial hemorrhage (ICH) of the pons and proximal ligation of the contralateral vertebral artery (VA) for the treatment of a fusiform aneurysm of the distal VA and discuss the possible etiologies of HFS in this patient. A 51-year-old male with an ICH of the pons was admitted to our hospital. Neuroimaging studies revealed an incidental fusiform aneurysm of the right VA distal to the origin of the posterior inferior cerebellar artery. Eight months after proximal ligation of the VA the patient presented with intermittent spasm of the left side of his face. Pre- and post-ligation magnetic resonance angiography revealed an enlarged diameter of the VA. The spasm completely disappeared after microvascular decompression.

Objective : Oriental medicinal plants reported to be used as anti-hypertensive drugs have been in vitro screened for inhibitory effects on angiotensin-converting enzyme (ACE). Methods : The bioassay is based on inhibition of plasma angiotensin-converting enzyme, as measured from the enzymatic cleavage of the Hip-His-Leu substrate into His-Leu. The plant material is extracted with hexane, ethylacetate, n-buthanol and water separately. Results : In total, 51 species (202 extracts) have been investigated and $400{\;}\mu\textrm{g}/ml$ of the solvent extracts from 26 extracts inhibit the enzyme activities by more than 50%. Among them, four samples of two plant species (buthanol and ethylacetate extracts of Salvia miltiorrhiza and buthanol and water extracts of Jeffersonia dubia) were found to posses a high ACE inhibition ability more than 90%. Conclusion : These results suggested that many Oriental medicinal plants have a antihypertensive effects by inhibition of ACE.

Empty cross-linked chitosan microcapsule was prepared by chemical cross-linking reaction using glutaraldehyde(GA). Chitosan bead was also prepared by coacervation method using sodium hydroxide. The technique involves the formation of a chitosan solution in the discontinuous phase of W/O emulsion. The factors influencing the emulsion stability have been examined to establish optimum conditions Chitosan microcapsules were useful for encapsulation of biological materials, and chitosan bead was useful to prepare the biologically active peptide-bound polysaccharide. As a model compound Gly-His-Lys, cell growth factor, was successfully coupled to chitosan bead.

This Paper reveals the costume culture of early 17th century from the study of private letters found in the tomb of Mrs. JinJoo Ha(\ulcorner - after 1652) excavated in 1989. The tomb was located at KooJi-myon, DalSung-kun, Kyung-Poong Province. Joo Kwak(1569-1617), Mrs. Ha s husband, didn t have a title from the government, but he was a clan in HyunPoong area who had enough land and servants. However, he didn't live togther with mrs. Ha, his second wife, he had to travel between SoRye and NonKong where his wife resided. The 40 or so private letters that contains valuable information that can help us to understand and reconstruct the costume culture of early 17th century in HyunPoong area. We believe that these materials contain somewhat general information that reveals costume of KyungSangDo area even though the materials are from a specific family. By accumulating information from real material like these letters, we also believe that it will give us a better understanding on the costume culture in 17th century, Choson dynasty. Furthermore, it will certainly help us to reconstruct a more realistic lifestyle of the time.

The major purpose of this study is to obtain the evident and visual structure of costume of priest with symbol through the Old Testament. Based on corroborative the Old Testament, this thesis analyzes the costume of priest. This compares Aaron with his sons. This compares the two onyx stones on the shoulder pieces with four rows of precious stones on the breastpiece. This compares the robe with the woven tunic. This era falls on about from the 15th century before Christ. The crafts men whom God have endowed with skill make the vestments. Due to the christian religion, the body was entirely concealed. The costume of priest were not only used as dignity but also grandeur. According to the Old Testament the colour of the costume has signified not only the colour sense but also important symbolic meanings. The priest wore, over undergarments, a woven tunic, and he wore over the tunic, a robe, an ephod, a breastpiece, a sash, using a turban as head covering. Gold, and blue, purple and scarlet yarn, and fine linen are used. Aaron and his sons must wear them whenever they enter the Tent of Meeting or approach the altar to minister in the Holy Place, so that they will not incur guilt and die.

Uric acid is the end product of the purine degradation pathway in humans. It is catabolized to allantoin by urate oxidase or uricase (E.C. 1.7.3.3.) in most vertebrates except humans, some primates, birds, and certain species of reptiles. Here we provide evidence that mouse transthyretin-related protein facilitates the hydrolysis of 5-hydroxyisourate, the end product of the uricase reaction. Mutagenesis experiments showed that the residues that are absolutely conserved across the TRP family, including His11, Arg51, His102, and the C-terminal Tyr-Arg-Gly-Ser, may constitute the active site of mTRP. Based on these results, we propose that the transthyretin-related proteins present in diverse organisms are not functionally related to transthyretin but actually function as hydroxyisourate hydrolases.

In order to increase the production of tryptophan by maximizing expression of recombinant trp plasmid, Klebsiella pneumoniae KC 105(pheA tyrA trpE trpR tyrR) was genetically modified. KC 107, inosine monophospate(IMP) auxotroph from KC 105 and KC 108, histidine(His) auxotroph from KC 107 were also derived respectively to increase phosphoribosylpyrophosphate(PRPP) production which is required for tryptophan biosynthesis. From KC 107 phosphoribosylpyrophosphate consumption which is required for tryptophan biosynthesis. From KC 107 and KC 108, KC 109 and KC 110, both arginine auxotrophs were derived respectively. To investigate the expression of recombinant trp plasmid in the selected K. pneumoniae mutants, the auxotrophic mutants were transformed with recombinant trp plasmids pSC 101-$trpE^{FBR}$, pSC 101-trpL(.DELTA.att) $trpE^{FBR}$ (pSC 101-trp-AF). Amount of tryptophan produced and activities of tryptophan synthase of $trpR^{-}$ mutant (KC 100) and $tyrR^{-}$ mutnat(KC 105) containing recombinant plasmid pSC 101-trp operon were increased by 30-40% as compared with KC 99(pheA tyrA trpE) containing recombinant plasmid pSC 101-trp operon. Activities of tryptophan synthase and production of tryptophan of KC 108 ($His^{-}$) and KC 109($Arg^{-}$) containing recombinant plasmid pSC 101-trp operon were increase by two-fold as compared with KC 107 containing pSC 101-trp operon.

Penetrating chest trauma caused by the components of one's own car is rare in motor vehicle accidents. We experienced two cases of penetrating chest injury caused by the sideview mirror of the patient's vehicle. One was a 25-year-old man. The sideview mirror penetrated the left chest, went through the diaphragm, and ruptured the spleen. He was in shock upon arrival at the emergency room. An emergency thoracotomy and laparotomy were done. The ruptured spleen was resected, the lung and the diaphragm were debrided and repaired, and the chest wall was reconstructed. The other patient was a 57-year-old male, who was transported to our emergency room with the sideview mirror of his truck stuck into his right chest wall as the result of an accident. He also had a right Bennet's fracture and an open fracture of the right tibia. Air had been sucked into the right pleural cavity through the wound. Multiple rib fractures and lung lacerations had also occurred. Removal of the sideview mirror, repair of the lacerated lung, and reconstruction of chest wall were done immediately. Both patients recovered without complication and were discharged.

Giant pulmonary bulla (GPB) is a rare manifestation of emphysema and usually enlarges gradually over time, occasionally resulting in complications. Hence, more often than not, the surgical intervention of a Bullectomy is the standard method of treatment for GPB. However, there are case reports that show the complete resolution of GPB after its inflammation process even without surgical intervention. A 51-year-old man was admitted to our clinic due to pleuritic pain. After a chest X-ray and CT scan, a new air-fluid level within the GPB was revealed in the right upper lobe of his lung. His clinical status had improved promptly with intravenous antibiotics. A one-year follow-up study showed the GPB was completely resolved.
