The regional distribution and relative frequency of endocrine cells in the GIT of the snakehead, Channa(Oph icephalus) argus were studied immunohistochemically. Five kinds of endocrine cells and one kind of nerve cell were identified in this study. A few numbers of secretin-immunoreactive cells were restricted to the cardia and fundus of the stomach. Moti-lin- and GRP-immunoreactive cells were rare in the epithelium of the distal and proximal intestines. PYY-immunoreactive cells were found in a few number in the pyloric caeca and were rare in the distal intestine. Substance P-immunoreactive cells were distributed relatively numerous from the fundus to the distal intetsine. Also, their nerve cells were detected in occurrence in the lamina propria in the distal intestine. No neurotensin-, met-Enk- and GIP-immunoreactive cells were found in the GIT of the snakehead.

가물치 (Ophicephalus argus CANTOR) ♂♀를 재료로 하여 두 실험군으로 나누어서 대조군에 부치사량인 25-${\gamma}$의 137Cs-${\gamma}$ 선을 조사하고 실험군에는 250${\gamma}$의 137Cs-${\gamma}$선을 조사 즉후 adrenaline (0.5cc/80g$\pm$18%)을 매일 투여하여 약 23$^{\circ}C$에서 사육하면서 혈청단백질의 전기영동상과 총혈청단백질의 변화를 1, 4, 7, 10 , 13 및 1일구간으로 분리 즉 시일적 경과로 조사하였다. 한편 가물치에서의 ${\gamma}$선 치사량은 310${\gamma}$이다. 1) 양군에서 일반적으로 1, 4, 7, 10 및 13 일구에 현저한 albumin 분설의 감소가 나타났다. 즉 대조군인 adrenaline 비투여 대조군에서 a1 및 a2 globulin 분설의 증가와 실험군이 adrenaline 투여 대조군에서 a1 및 $\beta$-globulin 분설의 증가에 다른 albumin 분설의 감소가 나타났다. 따라서 A/G 비고 역시 시일적 경과에 따라 감소된 치를 나타내었다. 그러나 특히 adrenabine 투여 대조군의 1 일간에서 A/G비가 현저하게 감소의 지체성을 나타내었다. 2) 총혈청단백질량은 양군에서 일반적으로 1, 4 및 7일구에서 현저하게 감소되나 13 미치 16 이구에서 가물치의 정상치로 근접된 치를 나타내었다. 그러나 특히 adrenaline 투여 조사군에서 4 및 7일구에서 현저하게 감소의 지체성을 나타내었다. 3) 상기의 결과로 미루어보다 명백하게 혈청단백질에 미치는 adrenaline 처리의 방어효과가 ${\gamma}$선 조사후 특히 초기상태에서 현저하게 초래된다고 생각도니다.

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.

A questionnaire survey including stool examination for the parasite ova, skin test, and enzyme-linked immunosorbent assay (ELISA) of the liver fluke to find the factors related with the prevalence of the parasite infestation was done toward 118 residents living in three villages of Song-jung, Yi-jung, and Chim-gok of Okok-myun, Goksung County, South Cholla Province. The results are as follows : 1. The prevalence of Clonorchis sinensis ova by the stool examination was 46.6%. The sensitivity and specificity of skin test to egg-positive cases were 63.5% and 68.9%. The sensitivity and specificity of ELISA to egg-positive clonorchiasis were 100% and 34.9%. 2. The prevalence of Clonchiasis was higher in male than in female. 45~64 year old group was the highest among age groups, and the longer the duration of living in the present residence was, the higher the prevalence was shown statistically significantly (p<0.01). 3. The present drinker had higher prevalence of Clonorchiasis significantly than the past drinker or non-drinker, and the more the frequency of drinking the higher the prevalence was shown significantly (p<0.05). 4. Those who took raw fish had significantly higher than persons who didn't take it or take cooked fish(p<0.05) and prevalence showed the tendency to be increased as the frequency to take raw fishes increased significantly(p<0.05). 5. Those who had taken a raw sweet fish(Plecoglossus altivelis) or snake-headed fish(Ophicephalus argus) showed significantly higher prevalence of infection with liver fluke than persons who didn't take the raw fish. 6. While 56.4% of persons infected with Clonorchiasis answered that they were healthy, only 13.0% of the subjects were careful for their health, and 41.8% experienced tests to diagnose liver flukes before they were examined by this survey. 7. While 56.4% of infected persons thought the prevalence was high in their community, 54.0% were afraid to be infected, 47.1% thought the infection might destroy their health, 25.5% took treatment drugs, and 18.2% took raw fish continuously after treatment. The above results confirmed that Goksung area was highly prevalent in Clonorchiasis, so it was necessary to push effective preventive program against liver fluke infection together with the program to diagnose and treat existing infected persons.
