천연장 소시지의 위생성과 최종제품의 미생물학적 저장 안정성을 개선시키기 위해 소시지 제조용 양장과 돈장에 감마선을 조사하여 소시지를 제조한 후 저장 중 미생물의 변화를 관찰하였다. 감마선 조사에 의한 돈장과 양장에 오염된 호기성 총균수는 선량이 증가함에 따라 감소하였고, 5 kGy의 감마선 조사로 약 5.5 log cycle의 미생물이 감소하였다. 비조사된 천연장을 사용하여 제조한 소시지의 경우 돈장과 양장소시지 모두 제조 직후 소시지의 호기성 총균수는 3.6 log 정도의 오염 수준을 나타냈고, 저장 10일에 이미 호기성 총균수가 약 7 log 수준으로 검출되었다. 반면 제조 직후 감마선 조사된 천연장 소시지의 미생물 수준은 양장의 경우 3 kGy에서 2.48과 돈장의 경우 2.78 log, 5 kGy에서 0.32와 0.6 log를 각각 나타내었다. 천연장에 대한 감마선 조사는 미생물의 초기 오염도를 상당히 감소시켜 최종제품의 저장성을 크게 연장시켰다. We gamma-irradiated to natural casings from lamb and pork to improve sanitary quality and microbiological shelf stability of sausage stuffed in animal intestine-induced natural casing from lamb and pork. The microbial changes of irradiated casings and the microbial growth of the sausages with gamma-irradiated natural casings were observed. Population of total aerobic bacteria was decreased by gamma irradiation, dependent upon the irradiation dose. The number of microflora in lamb and pork casings was reduced by about 5.5 log cycle at 5 kGy. Population of total aerobic bacteria of sausages stuffed in non-irradiated lamb and pork casing was about 3.6 log CFU/g after just manufacture and was about 7 log after 10 day storage. However, population of total aerobic bacteria of sausages with 3 kGy-irradiated and 5 kGy-irradiated casings was 2.48 and 0.32 log in lamb, and 2.78 and 0.60 log in pork, respectively. Gamma irradiation to animal intestine-induced natural casings was effective and thus, can be used for enhancing shelf life of final products due to reduction of the number of contaminated microflora.

In this study, using 26 experimental rabbits, proper doses of Hexachlorophene or 1,4-Bis-trichloromethylbenzol ere administered to the rabbits from 1st day of the infection with 500 metacercariae of Clonorchis sinensis. The larvicidal effects of the drugs were judged by the results of examination of Clonorchis eggs in feces and detection status of the adult worms from the liver at autopsy. And the following results were obtained. 1) In the control group, the detection rate of adult worm was 42.4%. 2) In the group of 10 times administration of Hexachlorophene 40mg(20mg/kg dody weight) in every day dose from 1st day of Clonorchis infection, there was no good larvicidal effect observed and the detection rate of adult worm was 19.0%. 3) In the group of 1,4-Bis-trichloromethylbenzol administration from 1st day of Clonorchis infection, there were no obvious larvicidal effects observed, and the detection rates of adult worm were 46.6%, 29.6% and 43.8% respectively in each of 10 times administration of the drug 100mg(50mg/kg body weight) in every day dose, 5 time administration of the drug 200mg(100mg/kg) in every day dose and 3 times administration of the drug 600mg(300mg/kg) in every other day dose.
