Résumé
Two 12-month-old cattle with anthelmintics containing trichlorfon the day before death presented to the Animal and Plant Quarantine Agency for diagnosis. In necropsy, they revealed enlargement of the spleens, redness of mucosa and serosa in stomachs and intestines, and friable kidneys. Histopathologically, hemorrhages in the spleens, omasums, abomasums, and intestines as well as renal tubular necrosis were observed. Trichlorfon was detected at above the lethal dose in the ruminal contents. Based on these findings, we diagnosed this case as death caused by trichlorfon poisoning.
Résumé
Eight rabbits exhibited head tilt and subsequently died. At necropsy, three rabbits had crusty deposits in ears and four had reddish lungs. The main histopathological features were severe diffuse suppurative meningoencephalitis (75.0% of rabbits), fibrinopurulent pneumonia (37.5%), and otitis externa (37.5%). Pasteurella multocida (P. multocida) was isolated from brains, ears, and lungs. The capsular serogroups of the isolates were untypable. Based on histopathological features and bacterial analysis results, the rabbits were diagnosed as P. multocida infection. P. multocida infections might result in considerable economic loss in commercial rabbit production facilities in Korea.

Human uterus has been known as a immune privileged site for the product of conception. At the feto-maternal interface, Fas system is a underlying main mechanism of maternal immune acceptance. To date, the TRAIL (TNF-related apoptosis-inducing ligand) system is known to be another pivotal mechanism. OBJECTIVE: To clarify the protein expression of TRAIL ligand and receptors in the normal and pathologic (preeclampsia, hydatidiform mole) placenta, chorioamnion, decidua. METHODS: we investigated the expression of TRAIL system in the above-mentioned tissues by using Western Hybridization. RESULTS: All tissues expressed TRAIL ligand and only a DcR2 among TRAIL receptors (DR4, DR5, DcR1, DcR2). CONCLUSION: we demonstrated the expression of TRAIL ligand and DcR2 protein at the feto-maternal interface of the normal and pathologic pregnancies. Further study regarding the expression of other receptors and quantitative analysis between normal and pathologic pregnancies should be followed.
