We compared the DNA sequence difference of isolates of Clonorchis sinensis from one Korean (Kimhae) and two Chinese areas (Guangxi and Shenyang). The sequences of nuclear rDNA (18S, internal transcribed spacer 1 and 2: ITS1 and ITS2) and mitochondrial DNA (cytochrome c oxidase subunit 1: cox1) were compared. A very few intraspecific nucleotide substitution of the 18S, ITS1, ITS2 and cox1 was found among three isolates of C. sinensis and a few nucleotide insertion and deletion of ITS1 were detected. The 18S, ITS1, ITS2 and cox1 sequences were highly conserved among three isolates. These findings indicated that the Korean and two Chinese isolates are similar at the DNA sequence level.

To determine the molecular phylogenic location of Plagiorchis muris, 28S D1 ribosomal DNA (rDNA) and mitochondrial cytochrome C oxidase subunit I (mtCOI) were sequenced and compared with other trematodes in the family Plagiorchiidae. The 28S D1 tree of P. muris was found to be closely related to those of P. elegans and other Plagiorchis species. And, the mtCOI tree also showed that P. muris is in a separate clade with genus Glypthelmins. These results support a phylogenic relationship between members of the Plagiorchiidae, as suggested by morphologic features.

Ninety cases of meniscus injury were treated by arthroscopic meniscetomy between March, 1988 and March, 1992. Eighty four cases were treated by arthroscopic partial, 5 cases by subtotal, and 1 case by total meniscectomy. All cases were followed up for more than 1 year. The results were as follows. 1. The ratio of male to female was 57 to 31, and that of right to left was 52 to 38. 2. There were 41 cases of medial meniscus and 49 cases of lateral meniscus. Longitudinal tears were 35 cases (39%), oblique tears were 20 cases (22%), horizontal tears were 15 cases (17%), and radial tears were 9 cases (10%). There was no difference in the shape of tear between medial and lateral meniscus. 4. The most common associated injury was anterior cruciate ligament tear. 5. The Tapper and Hoover scale was used to record the clinical results, and satisfatory results (exellent and good)were in 86% of cases.

During the past three years, in 1,607 selected general anesthetic cases, the authors have observed the influence of various drugs used in anesthesia and the patient's physical status upon the blood pressure during and immediately following endotracheal intubation. The results are as follows: 1) Blood pressure was higher during and for a period of 10 minutes after intubation than the control. 2) In the cases premedicated with Demerol and atropine intubation. Following intubation, however, blood pressure halothane anesthesia. 3) In patients with poor physical status, blood pressure more following intubation when either halothane or ether was employed. 4) Patients with poor physical status seemed to tolerate, considering the blood pressure change, ether better than holothane anesthesia.5) In the beginning of induction, blood pressure tended to fall less with gallamine than with succinylcholine chloride.

The case of 8 year old boy is presented, in whom huge mass on the lumbosacral region from birth and mild motor weakness of left leg with urinary incontinence. The operative using surgical microscope and pathological findings are discussed and reviewed of literature and a nosological classification of leptomyelolipoma given. The treatment underwent surgical microscope with good result. The importance of the surgical microscope is stressed.

Patients vary markedly in their responses to d-tubocurarine chloride. Despite an attempt to diminish the variation in responses to relaxants by standardizing experimental techniques, anesthetic concentration kept constant, acid-base status kept constant, premedication omitted, dosage calculated in terms of mg/sq meter body surface, the marked variation was found to persist. The dose related neuromuscular blocking effect of d-tubocurarine chloride was investigated using a rabbit common peroneal nerve anterior tibial muscle preparation. All experimental rabbits tracheas were intubated through tracheostomy under general anesthesia with Nembutal 40 mg/kg intravenously. Reapiration was controlled by a Harvard animal respirator. The body temperature was kept at 35-37 degrees C by a thermoblanket. The degree of neuromuscular block following intravenous d-tubocurarine chloride was measured by single twitch response. The common peroneal nerve was stimulated supramaximally using a square waves of 0. 2 msec duration at a frequency of 0.1 Hz, and each stimulus was repeated once every 10 seconds. The ratio of the twitch height was calculated. The results were as follows: 1) No neuromuscular blocking effect was observed with 0.1 mg/kg of intravenous d-tubocu- rarine chloride. 2) 100% of neuromuscular blocking effect was observed with more than 1mg/kg of intravenous d-tubocurarine chloride. This is 5 to 10 times higher than the human dose. 3) Dose related prolonged neuromuscular blocking effect was observed from d-tubocurarine chloride in rabbits.

We investigated the sero-prevalence of toxocariasis among healthy Korean adults in 1999. A total of 314 sera from normal inhabitants in Whachon-gun, Gangwondo, Korea was examined for specific antibody levels against excretory-secretory products of second stage larvae of Toxocara (TES). The presence of cross-reactions with other helminthiases such as cysticercosis, paragonimiasis, sparganosis or clonorchiasis was also checked by specific IgG ELISA. Sera showing positive reaction against TES were also tested by IgG immunoblot and by IgE ELISA. Out of 314 subjects, 16 was found to be positive by TES IgG ELISA and immunoblot, among whom 12 were also positive by TES IgE ELISA. Among the 16 seropositive samples, two sera showed positive reaction against Paragonimus and sparganum antigen, respectively. These results inferred that cross-reactions were negligible between toxocariasis and other helminthiases. Toxocariasis seroprevalence among Korean rural adults was detected to be approximately 5%.
