For the seed production of the topshell, Turbo cornutus SOLANDER an industrially important gastropod in Jeju Island, spawning season and induction of artificial spawning has been studied from April to December, 1978. The topshell were collected in the coat of Jeju Island, Jeju city, Seongsanpo, Moseulpo and Seogwipo areas. As the methods for induction of artificial spawning, the gonad were treated with NH₄OH and NH₄Cl seawater solution, or treated indiviual with seawater temperrature and exposure to air. The spawning season of the topshell in the coast of Jeju were supposed from June to Octorber, in which water temperature ranged from 21∼26℃. The peak spawning occurred from August to early in September at Jeju city, August to mid-September at Seongsanpo, mid-July to August at Moseulpo and mid- July to early in September at Seogwipo. The condition factor of the topshell at Seongsanpo and Seogwipo were higher in August and September, lower in June. And those of Jeju city and Moseulpo were higher in September, lower in July. The change of gonad maturity index of the topshell were showed higher in July, lower in August and September. The rate of meat weight to the total weight of the topshell at Jeju city and Moseulpo, Seongsanpo and Seogwipo were showed higher in May and July respectively, but their value were declined in August and September in all.

An induction of spawning by irradiated seawater with ultraviolet rays carried out in the laboratory to conduct fundamental studies on artificial spawning of some cultivated shells, i. e. Haliotis discus, Haliotis diversicolor superlexta, Turbo cornutus, Tapes variegata. Cyclina sinensis. The materials collected from Seongsan-po and Chuza-do during the spiwning season of these species. Stimulus methods for artificial spawning in this experiment were three methods ; UV-rays irradiated seawater used only, the UV-rays irradiation after temperature trestment and UV-rays irradiation after exposure to air. The rate of response and the time required for spawning on the amount of irradiation were observed. In an attempt to artificial spawning by irradiated seawater with UV-rays on the 5 species of shells, the rate of response for spswning in H. discus and H. diversicolor supertexta were effective to induce spawning but weren't in C. sinensis and T. variegata. The most effective discharging time was 4 hours after UV-rays irradiation. As for the amount of stimulus, it was obvious that the spawning rate increased with the amount of the irradiation and reduced the time required for initial spawning. UV-rays irradiation after temperature treatment and UV-rays irradiation after exposure to air were more effective than stimulus by UV-rays irradiated seawater used only. An ability of irradiated seawater caused spawning mediated by photochemical reactions in seawater depending on the enzyme catalyzing oxidative synthesis of prostaglandin. In this experiment, the results suggest that the effect of irradiated seawater with UV-rays to induce artificial spawning is to be recognition.

The effects of temperature, light and dark for the respiatory rate and the periodic oxygen consumption of the topshell. Turbo cornutus SOLANDER was measured. The oxygen consumption patterns showed circadian rhythms which increased from sunset to midnight and decreased from midnight to midday. The highest value of respiratory rate was appeared in about 2 hours after the sunset. In the temperature range of 10~20℃. the oxygen consumption increased with the increase of temperature, but markedly decreased at 30℃. The oxygen consumption in the animals acclimated to natural condition under 20~25℃ water temperature wzs superior to the light and dark condition, respectively. The oxygen consumption in the animals acclimated to light and dark condition were significantly decreased at 30℃ than 10℃ water temperature. The effect of temperature and light condition for respiratory rate was appeared similarly between A and B groups.

For the seed production of the topshell, Turbo cornutus SOLANDER an industrially important ga-stropod in Jeju Island, spawning season and induction of artificial spawning has been studied from April to December, 1978. The topshell were collected in the coast of Jeju Island, Jeju city. Seongsanpo, Moseulpo and Seogwipo areas. As the methods for induction of artificial spawning, the gonad were treated with NH_(4)OH and NH_(4)CI seawater solution, or treated indiviual with seawater temperature and exposure to air. The spawning season of the topshell in the coast of Jeju were supposed from June to Octorber, in which water temperature ranged from 21~26℃. The peak spawning occurred from August to early in September at Jeju city, August to mid-September at Seongsanpo, mid-July to August at Moseulpo and mid-July to early in September at Seogwipo. The condition factor of the topshell at Seongsanpo and Seogwipo were higher in August and September lower in June. And those of Jeju city and Moseulpo were higher in September, lower in July. The change of gonad maturity index of the topshell were showed higher in July,lower in August and September. The rate of meat weight to the total weight of the topshell at Jeju city and Moseulpo, Seongsanpo and Seogwipo were showed higher in May ant July respectively, but their value were declined in August and September in all. The difference of gonead maturation and spawning period were not observed between female and male. In this experiment the successful spawning were one time in the repeated treatments of twelve times of temperature seawater and all in five times of esposure to air. In this case the rate of fertilization was about 85.6~99.1% A tempt to spawning by injection of 1/100N-NH_(4)CI seawater solution to gonad of the topshell, and insomination by matured gonad immersed in 1/1000~3/1000 N-NH_(4)OH or 1/1000~3/1000 N-NH_(4)CI seawater solution for 10 to 15 minutes could not succeeded. In the development of the fertilized egg, the first eleavage occured 25 minutes the trochophore was observed 8 hours and 5 minutes, hatched out 11 hours and 5 minutes and the setting of the veliger began to three days after fertilization.

Objectives ; Urinary hippuric acid levels have been usually determined to evaluate workers exposes to toluene. Food and drink intake could affect urinary hippuric acid excretion and chi study was carried out to investigate what kinds of food and drink would affect urinary hippuric acid excretion. Methods ; The subjects were 136 medical school students. Authors measured urinary hippuric acid levels three times from 10 a. m. to noon; before, one hour after and two hours after food or drink-intake, and they were asked not to eat from the previous night(9 p. m) of testing. We selected six diets(bread and coffee, brown sauce noodle, Korean style meal, noodle, pork-galbi and rice and soybean stew and rice) , six fruits(apple, grape, orange, pear, persimmon and plum) and five beverages(Alps-D□, Demisoda□, Orange juice□, Pear juice□ and Pocari sweat□). Analysis of urinary hippuric acid was performed by high performance liquid chromatography. Results ; Intake of popular Korean diets, fruits and some drinks didn't affect urinary hippuric acid excretion. But intake of sodium benzoate-contained Alpa-D□ increased urinary hippuric acid excretion. Conclusions ; For the health examination on workers exposed to toluene, the history of diet and fruit intake can be negligible, but that of beverage intake should be included.
