Persistent trigeminal artery is an embryonic remnant of the anastomotic channel linking the internal carotid artery and the basilar artery. Cases of vertebrobasilar insufficiency caused by the persistent trigeminal artery with internal carotid artery stenosis has been described previously, but vertebrobasilar insufficiency entirely due to in situ stenosis of the persistent trigeminal artery has not been reported. A 71-year-old man presented with frequent dizzy episodes. The brain MRI showed no parenchymal lesions. MR angiography showed poor visualization of vertebrobasilar system. He was diagnosed as having vertebrobasilar insufficiency. Cerebral angiography revealed that there was complete occlusion at the vertebrobasilar junction, and the basilar artery was supplied by the persistent trigeminal artery which had severe stenosis at its origin. There was no stenosis of the internal carotid artery of both sides. We believe that this is the first report of vertebrobasilar insufficiency due to stenosed persistent trigeminal artery, without internal carotid artery stenosis.

5 bed sand filter, applying biological oxidation, was designed and studied on the treatment of water works. Never using any coagulant agent (drugs), which may cause water pollution in pre-treatment of head water, the author attempt a high rate filtration by the microorganism (nitrofication bacteria) end plant which populate in multi layer sand beds. The result are as follows ; In order to evaluate the oxygen effect on filtration, oxygen was injected in aeration tank attached to each filter tank while filtration, and NH3 was tested as a representative ingredient. It was found out that the aeration method was more effective, with over 33% of NH3 removal capacity, than the anerobic and this 5 bed filter showed double removal capacity of NH3 by comparing with conventional sand bed (2 stage bed). According to the examination of two kind of head water, pre-treated with coagulant agent and activated carben, the filtration capacity was affected by the polluted condition of head water, resulting that lower value of pollution and slower velocity of filtration showed more efficiency of NH3 removal. In this experiment NH3 content tested in treated water had a fairly good correlation with others.

Culture of human peripheral T lymphocytes with irnmobilized anti-CD3 rnAb plus IL-2 resulted in a marked proliferation and the enhancing IL-2Ra mRNA expression. The process of the T cell activation involves a series of biochemical events which ultimately lead to the proliferation and IL-2Ra mRNA expression. Although the above results have been observed, the celluar signal mechanisms between the proliferative response and the IL-2Ra mRNA expression through T cell receptor and IL-2 receptor remains unresolved. In the present study, We have used genistein (the selective PTK inhibitor) or chronic PMA treatment (depletion of intracelluar PKC activity), to investigate the role of PTK or PKC both in a synergistic proliferation and in the enhancing IL-2Ra mRNA expression by IL-2/anti-CD3. Genistein (30 ug/ml) completely blocked IL-2 induced T cell proliferation, and inhibited anti-CD3 induced T cell proliferation (93.4%). But genistein downregulated the IL-2Ra mRNA expression by IL-2, anti-CD3 and IL-2/anti-CD3. The chronic PMA treatment failed to inhibit the proliferation and the IL-2R#u mRNA expression by IL-2 alone. But PKC depleted T cells stimulated with anti-CD3 mAb showed the decrease of the proliferation (68.6%) and IL-2Ra mRNA expression. In activated with IL-2/anti- CD3, the proliferative response showed a half of reduction, but the IL-2Ra mRNA expression were not regulated. These results demonstrate that proliferative response to IL-2 appears to be dependent on PTKs activity and independent of PKC involvement, but the IL-2Ra mRNA expression may be required another signals. PTKs and PKC activity may be important in TCR/CD3 signaling. But IL-2/anti-CD3 are coupled up different signal transduction pathways responsible for the synergistic T cell proliferation and the enhancing IL-2Ru mRNA expression.

PURPOSE: To assess the role of MRI in the diagnosis of uterine anomaly. MATERIAL AND METHODS: MRI(n:15), hysterosalpingography(n:7) and ultrasonography(n:7) were performed in 15 patients with suspected MullerJan duct anomaly. Nine cases were proved by operation and six cases were diagnoed with imaging and clinical findings. According to Buttram and Gibbons modified classification, the anomalies were 4 cases of class I, 2 cases of class III, one case of class IV, and 8 cases of class V. RESULTS: MRI enabled accurate diagnoses of anomalies in all cases, but HSG and USG showed wrong diagnoses in 3 of 7 cases and in 1 of 7 cases. CONCLUSION: MRI, especially T2-weighted images parallel to long axis of uterine corpus, was very useful in diagnosis of the Mullerian duct anomaly, because it could depict exactly the external fundal contour, intercornual distance, septum, transverse vaginal septum, and associated abnormalities such as hematocolpos and hematometra.
