The purpose of this study was to examine the effects of taurine and vitamin E on ovarian granulosa cells damaged by bromopropane (BP) in pigs. We evaluated cell viability, plasma membrane integrity (PMI) and apoptotic morphological change in porcine ovarian granulosa cells. The cells were treated with 1-BP (0, 5.0, 10, and 50 μM), 2-BP (0, 5.0, 10, and 50 mM), taurine (0, 5.0, 10, and 25 mM), and vitamin E (0, 100, 200, and 400 μM) for 24 h. 10 μM 1-BP and 50 μM 2-BP inhibited viability and PMI, and induced apoptosis in porcine ovarian granulosa cells (p < 0.05). Cell viability and PMI were increased by taurine (10 and 25 mM) and vitamin E (100 and 200 μM), and apoptosis decreased (p < 0.05). Finally, the porcine ovarian granulosa cells were co-treated with BPs (10 μM), taurine (10 mM) and/or vitamin E (200 μM). Cell viability and PMI in the co-treated cells were increased, and apoptosis was decreased. In conclusion, taurine and vitamin E can improve cell viability and inhibition of apoptosis in porcine ovarian granulosa cells damaged by bromopropane.

제올라이트 함유 폴리에틸렌 필름의 최대응력, 파단신율 및 인열강도를 측정한 결과 전반적으로 금속이온으로 치환한 제올라이트 필름에 비해 계면활성제로 치환한 제올라이트를 함유한 필름의 물성이 순수 LDPE필름의 물성에 비해 큰 감소 없이 일정하게 유지되는 사실을 확인하였다. 한편 선도유지기능 실험 결과 일부의 양이온성(Al 및 Ag) 또는 계면활성제로 개질된 제올라이트 필름들이 시험된 과채류에 대하여 일반 LDPE 포장용 필름보다 우수한 선도유지기능
