The present work was to observe the wormicidal effects of the external mucous substance of Carassius carassius and Pseudorasbora parva on cercaria, metacercaria (liberating) and adult of Clonorchis sinensis. The mucous substance which was extracted by ether was separated into various spots on the silica gel thin layer chromatography and separated into various fractions in the silica gel column chromatography, using petroleum ether(30 percent) and chloroform(70 percent) as solvent. R(f) 0.952 value of the silica gel thin layer chromatography and the first fraction (reddish yellow) frorn the silica gel column chromatography of the ether extracts from C. carassius had the wormicidal effect on all of the developing stages of C. sinensis. Cercaria was killed within 14 minutes, metacercaria within 27 minutes and adult 2.5 hours by the first fraction. But in the normal saline solution (control) and in the other fraction, cercaria and metacercaria were alive more than 24 hours and adult more than 72 hours. The extracts from the mucous substance of P. parva that is well penetrated by cercaria had no wormicidal effect on them.

BACKGROUND: Self-expandable metallic stent is an effective method in palliative treatment of malignant biliary stricture. However, it is controvesial in benign biliary stricture due to recurrent jaundice, cholangtitis, and finally, obstruction of stent. The purpose of this study was to determine the long-term effectiveness of Gianturco expandable metallic stents in benign biliary strictures. METHODS: We inserted Gianturco self-expandable metallic stent in 13 patients (42~69 years old, 6 men and 7 women) with benign biliary stricture between November 1991 and September 1994 in Wonkwang University Hospital. All patients had a previous history of biliary surgery and underwent balloon dilatation procedure for management of strictures. Insertion routes were percutaneous transhepatic biliary drainage tracks in 8 cases and T-tube tracks in 5 cases. The insertion site was the right intrahepatic duct in 5 cases, the left intrahepatic duct in 2 cases, both intrahepatic ducts in 1 case, common hepatic duct in 1 case, and distal common bile ducts in 4 cases. The stents used were 2~6cm in length and 8~12mm in diameter. The follow-up period was 46months to 81months(mean, 67months). RESULTS: The initial technical success rate was 100% with good immediate patency in all patients. Nine patients(69.2%) had no recurrence of the initial strictures during the follow-up period and 4 patients(30.7%) had further symptoms of biliary obstruction caused by recurrent cholangitis or intrahepatic duct stone formation. These 4 recurrent biliary strictures were treated by surgical methods. The recurrent stricture sites were distal common bile duct(1case), left intrahepatic duct(1case), both intrahepatic ducts(1case), and Roux-en-Y hepaticojejunostomy site(1case). CONCLUSIONS: According to the results of long-term follow-up, expandable metallic stent is a useful method in recurrent biliary strictures, especially in the case where operation is not feasible; poor risk patients, patients refusing operation, multiple biliary operation.

Malignant hyperthermia still carries a high mortality despite of the increased understanding of the problem involved. A 33 year old relatively healthy male patient was admitted to this hospital via emergency room because of panperitonitis due to peptic ulcer perforation. We experienced acase of malignant hyperthermia which developed 20 minutes after induction of general anesthesia with thiopental sodium, succinylcholine chlovide, halothane, N2O and O2. The body temperature(esophageal) rose altupthy up to 41.2 degrees C and continued as a high fever for about 3 hours. The blood pressure and heart rate also increased and ventricular dyarrhythmia appeared. The etiology, triggering gactors, factors, clinical features, diagnosis treatment and safe anesthesia of malignant hyperthermia are discussed.

Fibrous dysplasia (FD) is a rare skeletal disorder characterized by abnormal fibro-osseous connective tissue replacing normal bone. Despite its benign behavior, craniofacial FD can cause morphological disfigurement, headache, and even blindness as a result of the produced mass effect. Surgical resection is recommended when the patient shows apparent clinical symptoms or aggravating facial asymmetry. Postoperative complications have been reported, such as hematoma, surgical site infection, abscess formation, resorption of the bone graft used for reconstruction, and recurrence. An aneurysmal bone cyst (ABC) is a rare benign bony lesion that can occur secondary to preexisting bone tumor. Secondary ABCs in craniofacial FD are extremely rare in the literature, accounting for less than 30, all of which are either case reports or series. We report an extremely rare case of symptomatic secondary ABC arising from craniofacial FD that had been misdiagnosed with abscess formation or recurrence and was surgically removed. Notably, 17 years elapsed between the primary surgery and the complication of secondary ABC. The patient underwent total removal of secondary ABC. After surgery, symptoms were relieved, with no recurrence observed during a 6-month follow-up.

The wound healing effect of topical application of the recombinant human epidermal growth factor(rhEGF) on full-thickness dermal injury was investigated. Two full-thickness excisions were made on the back of the experimental animals. The rhEGF was applied twice a day and the rate of wound closure was measured every day for 14 days. On the seventh postoperative day, the histological findings of epithelization and granulation were examined by Massons tichrome stain, and immunohistochemical staining for proliferating cell nuclear antigen (PCNA) and alpha-smooth muscle actin(alpha-SMA). The wound size was a significant reduction in the rhEGF treated groups as compared with the control group (p<0.05). However, there was no statistical difference in the wound size among the concentrations of the rhEGF treated group. Histological examination revealed that epithelization and granulation was increased significantly in the rhEGF group compared to control group (p < 0.01, 0.05). PCNA and alpha-SMA immunoreactive cells were observed at the margin of wound and the rhEGF treatments significantly increased the number of PCNA and alpha-SMA immunoreactive cells as compared to those of control group (p < 0.01, 0.05). Taken together, these findings suggest that rhEGF enhance the epithelial wound healing by the stimulate of cell proliferation. The wound contraction might be also affected by rhEGF application.

Out of all oral malignant tumor, malignant lymphoma occurs in only 3.5%. Especially, most of the primary malignant lymphomas, which occur in the head & neck region are high-grade diffuse large B-cell lymphoma and mucosa-associated lymphoid tissue (MALT) marginal zone B-cell lymphoma is very rare. In the head & neck region, malignant lymphoma is reported to occur in the thyroid, salivary gland, trachea, larynx, orbital lobe and the Waldeyer's ring. Among the Waldeyer's ring, palatal tonsil is reported to be the most common region, but, only 1 case report was published in Korea. Until now, there were no case reports of MALT lymphoma that occurred in the tongue. The purpose of this case report is to report and discuss on a case of MALT lymphoma of the tongue.

Basal cell nevus syndrome is inherited as an autosomal dominant trait with variable expressivity. This syndrome comprises a number of abnormalities such as multiple nevoid basal cell carcinomas of the skin, skeletal abnormalities as bifid rib and fusion of vertebrae, central nervous system abnormalities as mental retardation, eye abnormalities, and multiple odontogenic kerato cysts. In 1960, Gorlin and Goltz first described the features of this disease as constituting a true syndrome; since then, it has been realized that it is much more complex and encompassing than initially thought. This patient has many symtoms of basal cell nevus syndrome. we has known multiple jaw cysts through panorama and facial computed tomography. He has hyperchromatism on basal cell through skin biopsy. In ophthalmologic consult, he has blindness on right. On his past medical history, amputation was done on his toes for polyductalism. - So we report with literature reviews

The present work which was investigated in July 1979, was to observe the wormicidal effects of the external mucous substances of 9 species of fresh water fishes (Cyprinus carpio, Parasilurus asotus, Anguilla japonica, Ophicephalus argus, Carassius carassius; golden crusian carp, Misgurnus anguillicaudatus, Zacco platypus, Pseudorasbora parva and Carassius carassius; crusian carp) on cercaria, liberated metacercaria and adult of Clonorchis sinensis. The mucous substances extracted by ether from the above 9 species of fishes were separated into many spots on the silica gel thin layer chromatography, and divided into many fractions in the silica gel column chromatography which used petroleum ether (30 percent) and chloroform (70 percent) as a solvent. On the silica gel thin layer chromatography of ether extracts from 9 species of fresh water fishes, each of the Rf. values which had wormicidal effect on the cercaria of C. sinensis were different from others; Rf. value of C. carassius (crusian carp) was 0.937, 0.709 in O. argus, 0.612 in A. japonica, 0.576 in P. asotus, 0.451 in C. carpio, 0.701 in Z. platypus, 0.385 in C. carassius(golden crusian carp) and 0.15 in P. parva. Time for wormicide was different from each other, too. It took 14 min. in a case of C. carassius(crusian carp), 25 min. in Z. platypus, 26 min. in C. carassius(golden crusian carp), 28 min. in C. carpio, 30 min. in P. asotus, 35 min. in O. argus, 40 min. P. parva and 180 min. in A. japonica. But any of the spots of M. anguillicaudatus did not show wormicidal effect on the cercaria within 10 hours. In the silica gel column chromatography of ether extracts from 9 species of fresh water fishes, the fractions which had wormicidal effect on the metacercaria of C. sienesis were different from each other; in a case of C. carassius(crusian carp), the first fraction only had wormicidal effect, the 2nd in P. asotus, the 3rd in O. argus, the 4th in C. carassius(golden crusian carp), the 2nd in C. carpio and the 4th in P. parva. Time for wormicide was 40 min. in C. carassius(crusian carp), 52 min. in P. asotus, 74 min. in C. carassius(golden crusian carp), 92 min. in O. argus, 95 min. in C. carpio and 140 min. in P. parva, but any of the fractions of A. japonicas, M. anguillicaudatus and Z. platypus did not show wormicidal effect within 10 hours. The fractions which had wormicidal effect on the metacercaria of C. sinensis had also the same effect on the adult, but it took longer time to kill them. It took 3 hours in a case of C. carassius(crusian carp), 4 hrs. in C. carassius(golden crusian carp), 5 hrs. in P. asotus, 6 hrs. and 6 min. in O. argus, 6 hrs. and 10 min. in C. carpio and half and 6 hrs. in P. parva. But any of the fractions of A. japonica, M. anguillicaudatus and Z. platypus did not show wormicidal effect within 24 hrs.

PURPOSE: Early traditional methods of surveillance to detect failing graft relied on recurrence of symptoms, change of pedal pulses, or a decrease in the Ankle-Brachial Index (ABI). More recently, graft surveillance with Duplex scan which has become an appropriate first-line alternative has been shown to be effective in identifying the patency of threatened femorodistal graft. The purpose of this study was to determine the relationship and significance among ABI change, run-off resistance score, and Duplex scan parameters in femorodistal graft bypass. METHOD: Among 52 patients who received femorodistal bypass, thirty-one femorodistal grafts (19: above knee, 12: below knee) which had followed up for more than 2 years were followed up by ABI at regular interval and Duplex scan at 2 year. Those were grouped according to the grade of ABI decrease as follows; Group I: <0.1 ABI decrease, Group II: 0.1or= 0.2 ABI decrease. Peak systolic flow velocity (PSFV) ratio, luminal diameter at near proximal and distal anastomosis, mean body graft velocity (cm/sec) were evaluated. Runoff resistance score was calculated by the finding of the pre-operative angiogram. RESULT: In proportion to the severity of ABI decrease, proximal and distal peak systolic flow velocity (PSFV) ratio and stenosis (%) increased, mean body graft velocity decreased. Significant statistical difference between groups were shown as follows; Group II and IV: distal PSFV ratio (2.17 vs 2.95, P=0.02), proximal stenosis (32.8% vs 47.4%, P=0.026), distal stenosis (21.7% vs 62.0%, P=0.007), mean body graft velocity (81 cm/sec vs 46 cm/sec, P=0.02) Group III and IV: distal PSFV ratio (2.29 vs 2.95, P=0.02), distal stenosis (40.5% vs 62.0%; P=0.003), body flow velocity (70 cm/sec vs 46 cm/sec, P=0.02). The higher runoff resistance score was, the more distal PSFV ratio, distal stenosis increased, but proximal stenosis, PSFV ratio, and mean body graft velocity did not change significantly. CONCLUSION: This study shows that higher decrease in ABI (>0.2) is well correlated with critical Duplex parameters. Longer graft patency and economic benefit may be obtained by active evaluation of failing graft using by Duplex scan when the ABI decrease is more than 0.2 in femorodistal graft bypass at regular examination.

The epidermal mucous substances of C. carassius which were extracted by ether were separated into various spots on the silica gel thin layer chromatography and separated into various fractions in the silica gel column chromatography, using petroleum ether (30 percent) and chloroform(70 percent) as a solvent. The wormicidal effects of the spots and the fractions on the cercaria, the liberating metacercaria and the adult of C. sinensis, were observed by month giving attention to ambient water temperature. Among the four spots of the thin 1ayer chromatography of the ether extracts from C. carassius, the uppermost first spots (Rf. 0.924-0965) had a strong wormicidal effect on the cercaria in May, June, July, August and September, and the cercaria which came in contact with the materials was killed in 29-49 min., but in other months (Rf. 0.612-0.752) it was killed only after 50-115 min. In column chromatography of ether extracts from C. carassius, the first fractions which had a wormicidal effect killed the metacercariae within 38-163 min. in May, June, July, August, and September, but it took about 120-458 min. to kill them in other months, meanwhile the wormicidal time of the fractions on the adults was 445-835 min. in May, June, July, August and September, but was 878-2,130 min. in other months. The Rf. value of the uppermost first spot of the thin layer chromatography of ether extrart from the mucous substance of C. carassius which was reared in the aquarium controlled at 23 C was 0.79, and its first fraction of column chromatography killed the metacercaria and the adult of C. sinensis within 315, and 1,850 min. respectively. As summarized above, the wormicidal materials of the epidermal mucous substances of C. carassius had no relation to ambient water temperature, but the secretion period of this wormicidal materials was the same as the liberating period of the cercariae from Parafossarulus manchouricus.
