  • Concentrations of dioxins, furans and dioxin-like polychlorinated biphenyls (DL-PCBs) were determined in crucian carp collected from eight locations mainly along the Nakdong River during 2004. Total dioxin concentrations which include concentrations of dioxins, furans and DL-PCBs ranged from 0.053 to 0.614 pg WHO-TEQ $g^{-1}$ wet wt. with a mean of $0.342{\pm}0.213$ pg WHO-TEQ $g^{-1}$ wet wt. The proportions of dioxins, furans and DL-PCBs to total dioxin TEQ were 4%, 12% and 84%, respectively. The results suggest that concentrations of dioxin-like polychlorinated biphenyls should be determined when total dioxin TEQ accumulated in freshwater fish is investigated.

  • The acute and subacute toxicity of fumomsin $B_1$ was evaluted in fingerlings of common carp, Cyprinus carpio. Dipping of fish for acute toxicity was performed for a period of 48 hours, and the $TLm_{48h}$ value(median tolerance limit) was more than 1000 ppm in common carp. Severe damages were observed in various organs and among them, clubbing of gill lamella, lytic degeneration and vacuolation of liver cells, and epithelial edema of renal tubules were relatively prominent. The most significant changes were hyperbasophilic foci of liver cells in subacute toxicity test and these can imply the possibility of hepatocarcinogenecity of fumonisin $B_1$.

  • Fishes detect various sensory stimuli, which may be used to direct their behavior. Especially, the visual and water flow detection information are critical for locating prey, predators, and school formation. In this study, we examined the specific role of these two different type of stimulation (vision and vibration) during the obstacle avoidance behavior of carp, Cyprinus carpio. When a visual obstacle was presented, the carp efficiently turned and swam away in the opposite direction. In contrast, vibration stimulation of the left or right side with a vibrator did not induce strong turning behavior. The vibrator only regulated the direction of turning when presented in combination with the visual obstacle. Our results provide first evidence on the innate capacity that dynamically coordinates visual and vibration signals in fish and give insights on the novel modulation method of fish behavior without training.

  • The acute and subacute toxicity of fungicide folpet was evaluated in fingerings of common carp, Cyprinus carpio and goldfish, Carrassius auratus. Dipping of fishes for acute toxicity was performed for a period of 24h, and the TLm value(median tolerance limit) was 1.52 ppm in common carp and 1.45 ppm in goldfish. Severe damages were observed in various organs and among them, clubbing of gill lamella, lytic degeneration and vacuolation of liver cells, and epithelial edema of renal tubules were relatively prominent. The most significant changes were hyperbasophilic foci of liver cells in subacute toxicity test and these can imply the possibility of hepatocarcinogenecity of folpet.

  • This study investigated cytogenetic and hematological and histological characteristics between diploid and spontaneous triploid on Cyprinidae (Crucian carp, Carassius auratus; crucian carp, C. cuvieri and common carp, Cyprinus carpio) in four major rivers of Korea. In our results, DNA contents of triploid Cyprinidae were 50% more than those of diploid Cyprinidae. Also, erythrocyte size of triploid Cyprinidae was 50% larger than those of diploid Cyprinidae. In all sampling rivers, sex ratios of C. auratus were biased to female, and especially, triploid groups of C. auratus were all female groups (p<0.05). In principle, sex ratios of C. cuvieri and common carp were equivalent between male and female.

  • Objectives: The maintenance of the healthy periodontal ligament cells of the root surface of donor tooth and intimate surface contact between the donor tooth and the recipient bone are the key factors for successful tooth transplantation. In order to achieve these purposes, a duplicated donor tooth model can be utilized to reduce the extra-oral time using the computer-aided rapid prototyping (CARP) technique. Materials and Methods: Briefly, a three-dimensional digital imaging and communication in medicine (DICOM) image with the real dimensions of the donor tooth was obtained from a computed tomography (CT), and a life-sized resin tooth model was fabricated. Dimensional errors between real tooth, 3D CT image model and CARP model were calculated. And extra-oral time was recorded during the autotransplantation of the teeth. Results: The average extra-oral time was 7 min 25 sec with the range of immediate to 25 min in cases which extra-oral root canal treatments were not performed while it was 9 min 15 sec when extra-oral root canal treatments were performed. The average radiographic distance between the root surface and the alveolar bone was 1.17 mm and 1.35 mm at mesial cervix and apex; they were 0.98 mm and 1.26 mm at the distal cervix and apex. When the dimensional errors between real tooth, 3D CT image model and CARP model were measured in cadavers, the average of absolute error was 0.291 mm between real teeth and CARP model. Conclusions: These data indicate that CARP may be of value in minimizing the extra-oral time and the gap between the donor tooth and the recipient alveolar bone in tooth transplantation.

  • 잉어체내에서 $^{14}C-carbofuran$의 흡수, 분포, 대사 및 배설시험을 이해 carbofuran을 40ppb 수준으로 처리하였다. 약제처리 12시간 후에 적출된 잉어의 조직(간, 신장, 창자, 쓸개)과 혈액에서 방사능$(^{14}C)$의 검출율이 가장 높았다. 잉어의 간과 신장에서 carbofuran은 3-ketocarbofuran과 3-hydroxycarbofuran으로 대사되었고 주요 대사산물로는 3-hydroxycarbofuran이었다. 약제처리 후 조직에서 그의 분포율이 가장 높은 시간대의 잉어를 공시수에 분양하여 배설시험을 수행한 결과 carbofuran은 분양 3시간 후에 배설율이 현저히 증가하였고 검출된 대사산물로는 3-ketocarbofuran과 3-hydroxycarbofuran으로 이 시간 동안의 배설시험에서 이들 대사산물의 검출정도는 각각 32.3%와 52.8%였고 미확인 대사산물은 2.6%이었다.

  • Crucian carp Carassius carassius L., Skate-fish Parasilurus asolus, snake head Ophicephalus argus and loaches Misgrunus anguillicaudatus have been esteemed as the tasty fresh water fish in Korea. However, a little has been studied on their taste compounds. Amino acids, nucleotides and their related compounds as the taste giving substance in the dorsal muscle of crucian carp, skate-fish, snake head and loaches were analyzed. Hypoxanthine (4.6-30.3 ${\mu}mole/g$, on dry base) was dominant among the nucleotide materials in the dorsal muscle of crucian carp, skate-fish, and snake head while IMP (12.8 ${\mu}mole/g$) was detected with the highest amount in loaches meat. IMP was also high in the muscle of skate-fish (13.5 ${\mu}mole/g$) and snake head (5.6 ${\mu}mole/g$). The other nucleotide materials, CMP, UMP, GMP, AMP, and inosine were present less than 2.0 ${\mu}mole/g$ in all the fish meat. The amino acid composition showed that glutamic acid and aspartic acid were the most abundant in the dorsal muscle of crucian carp, skate-fish, snake head and loaches. The analysis of free amino acids showed that histidine, lysine, glycine, and serine were the leading amino acids in the dorsal muscle of crucian carp, alanine, serine, and lysine were of skatefish, glycine, lysine, alanine, and serine were of snake head, while alanine, serine, and glycine were of loaches. Isoleucine and leucine were detected in trace amount in the muscle of skate-fish, snake head, and loaches. It is believed that alanine, Iysine, serine, glycine and histidine along with IMP and hypoxanthine may play an important role as the taste compounds in fresh water fish.
