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.

Melorheostosis is a rare entity while causes pain and stiffness in a limb and has an unknown etiology. It is characterized by roentgenographic appearance of melting wax dripping down one side of a candle along the major axis of long bone. The present case represents a melorheostosis of the left tibia accompanied by synovial chondromatosis in the left knee. Good result was obtained by arthrotomy of the left knee and removal of the bony masses in the joint.

Primary lymphoma of uterine cervix is rare disease, which usually occurs in postmenopausal periods. The usual symptoms are vaginal bleeding, postcoital bleeding. The most common pathologic feature is a diffuse cell type, B-cell line. Pap smear is not helpful in diagnosis because it is stromal origin. Biopsy confirms the diagnosis. Treatment consists of radiation therapy and/or chemotherapy. The prognosis of the disease is dependent upon Ann arbor stage and International index score rather than FIGO stage. We experienced one case of primary lymphoma of cervix and report it with a brief review of literature.

Benzene and toluene, which are widely used aromatic hydrocarbons in workplace, are recently proved to cause health hazards due to their toxic effects. This study investigated the influence of toluene on the urinary excretion of benzene metabolite by administering short term exposure limit(STEL) of these compounds(i.e., 13.8mg/kg of benzene and 108.8mg/kg of toluene) intraperitoneally into Sprague-Dawley rats. After administration, urinary phenol concentration of rat was measured by gas chromatography for every three hours. Data were analyzed by non-parametric statistical methods using Kruskal-Wallis multi-sample test and Mann-Whitney U test. The following results were obtained: 1. Administration of STFL-benzene increased urinary phenol concentration in rats. 2. Urinary phenol concentration was increased logarithmically according to the dosage of benzene. 3. Excretion of phenol in urine was decreased when benzene and toluene were administered simultaneously compared with administering benzene alone. In Summary, these results reveal that administration of STEL of toluene has antagonistic effect of urinary excretion of benzene metabolite in rats.

PURPOSE: To evaluate MR characteristics of periosteal reactions and subperiosteal abscesses in osteomyelitis as compared with radiographs. MATERIALS AND METHODS: We retrospectively reviewed 28 patients(18 males, 10 females) with osteomyelitis. Nineteen patients underwent MR imaging with 0.5 T. We analyzed for morphologic patterns, intervals of appearance and disappearance of periosteal reactions after symptom onset. Twenty-three patients were confirmed by surgery and 5 patients by the radiologic findings, clinical and laboratory data. RESULTS: Periosteal reaction appeared as low signal intensity arc on the T1- and T2-weighted axial images. In 3-7 days after symptom onset, periosteal reactions and subperiosteal abscesses were noted on MR imaging, and only two of eleven patients were noted in radiographs. Periosteal reactions of 8-14 days after symptom onset were demonstrated in all of 13 patient on MR, and 9 on plain radiographs. All patients with 2 weeks after symptom onset showed perioste.al reaction in plain film and MR. The periosteal reactions persisted until approximately 2 to 3 months after treatment on follow up radiographs. CONCLUSION: Periosteal reactions in osteomyelitis are detected on the MR imaging earlier than plain film. MR is valuable in detecting subperiosteal abscess which is not appecent in simple radiographs. Periosteal reactions can be seen on MR in 3 days after symptom onset and persist for 2-3 months after treatment.

PURPOSE: We studied the association between systemic risk factors and idiopathic macular hole. In addition, we analyzed the mechanism by which systemic risk factors affect the development and progression of macular hole. METHODS: Seventy patients with idiopathic macular holes were compared with 30 sex- and age- matched controls. The vascular viscosity profiles, and coagulation, biochemical and hormone factors were evaluated as systemic risk factors. RESULTS: The levels of fibrinogen and blood estrogen were significantly higher in the idiopathic macular hole group than in the control group. Also the fibrinogen level increased with the progression of macular hole. But there was no significant difference between the two groups with respect to the remaining factors. CONCLUSIONS: These results support the possibility that fibroproliferative factors from platelet increase in patients with idiopathic macular hole, and that fibrinogen is the parameter that increases among the fibroproliferative factors. This study also suggests that blood estrogen is important in the development of macular hole.
