Most vascular disorders tend to affect both the brain and heart, and among them, a clinical syndrome constituting cerebral aneurysm and aortic coarctation(AC) has been well recognized. Persistent hypertensive impact to the cerebral vasculature with developmental anomaly of the neural crest, precursor of ectomenchymal, would be closely associated with development of the cerebral aneurysm in AC. Gonadal steroid hormone, a guardian of the cardiovascular system, has been known for its protective effects on the vascular wall. Gonadal steroid hormone (androgen) insensitivity such as 46, XY female syndrome may increase the risk of hypertention and subsequent vascular anomalies. The authors report on a 46-year-old 46, XY female patient with AC who underwent surgical clipping of the ruptured cerebral aneurysm. Clinical implications and proposed pathogenetic mechanisms of aneurysm in this intersex syndrome are presented and discussed.

PURPOSE: To evaluate characteristic MR findings of craniocerebral anomaly and its relationship with neurologic manifestations. MATERIALS AND METHODS: We retrospectively reviewed MR images of 36 patients with craniocerebral anomaly diagnosed by MRI and clinical courses. We correlated the characteristic MR findings in 41 lesions with neurologic manifestastions focusing on seizures and developmental delay. RESULTS: Twenty-three patients with seizures consisted of 14 patients(60%) with neuronal migration disorders and seven(30%) with phakomatosis, among which 18 patients(78%) had generalized type of seizures. Locations of the lesions were the parietal lobes in 11 patients(52%) and the subependymal or periventricular regions in seven(33%). Two patients with tuberous sclerosis had the lesions in both parietal and subependymal areas. Nine patients had the signs of developmental delay that were seen in the four(44%) with schizencephaly, two (22%) with tuberous sclerosis, two(22%) with heterotopia, and one(ll %) with pachygyria. CONCLUSION: Neuronal migration anomaly was relatively common lesion that presented neurologic manifestations such as seizures and developmental delay. Generalized type of seizures was common. We were able to diagnose these anomalies using the MRI that helped establish therapeutic plans.

3.Modulatory action of enrofloxacin in lipopolysaccharide-induced hyper-activated mouse spleen cells
Korean Journal of Veterinary Research 2019;59(2):75-80
Enrofloxacin, a fluoroquinolone, is a broad-spectrum antibiotic widely used in veterinary medicine that inhibits the action of bacterial DNA gyrase, resulting in anti-bacterial effects. This study was performed to examine whether enrofloxacin has modulatory and anti-inflammatory activity on immune cells. A few studies have reported the anti-inflammatory effects of enrofloxacin. In this study, we used mouse spleen cells treated with lipopolysaccharide (LPS) and examined the effects of enrofloxacin. Several assays were performed in LPS-treated spleen cells after the enrofloxacin treatment. Enrofloxacin inhibited the metabolic activity and mitochondrial membrane potential of LPS-treated spleen cells significantly. On the other hand, enrofloxacin did not alter the proportion of the subsets in spleen cells, and did not induce cell death. The production of tumor necrosis factor-alpha in LPS-treated spleen cells was inhibited by enrofloxacin. Overall, enrofloxacin had modulatory activity in spleen cells treated with LPS. These data may broaden the use of enrofloxacin as an antibiotic with anti-inflammatory activity in veterinary clinics.

OBJECTIVE: PCB cervical instrument is a newly introduced fusion device which comprises cervical plate, cage (spacer) and screw system. It is developed to enhance fusion rate and stability, as well as to reduce complications related to hardware failure. We investigated the efficacy of clinical and radiological results of PCB instrument and Lubboc bone. METHODS: From August, 1998 to October, 1999, authors performed 54 cases of anterior cervical interbody fusion with PCB instrument and Lubboc bone. Retrospective analysis was undertaken based on clinical and radiological findings. Clinical improvement was evaluated according to Odom's criteria. Cervical plain films and tomography were taken every 2 months to evaluate the degree of interbody fusion and disc height changes. RESULTS: Bone fusion was observed in 36 cases(90%) over 6 months after operation, and during which time there was no significant interval change. There were 3 cases of hardware dislodgement. Disc height was increased significantly and preserved in all cases. Clinical outcome over good degree was seen more than 94% of patients. CONCLUSION: Longer follow-up period and comparative studies to similar instrument appear to be necessary, but this instrumentation system has shown high fusion rate and fewer adverse effects in our series. We believe this system might be indicated for the treatment of cervical trauma and degenerative disease in selective cases.

Tuberculosis mainly develops in the lung, but may also rarely invade other parts of the abdominal region. Abdominal tuberculosis is associated with pulmonary tuberculosis in approximately 15% of cases, and abdominal tuberculosis primarily develops in the terminal ileum and lymphatic gland. Moreover, hepatic tuberculosis is uncommon and is usually accompanied with active pulmonary or miliary tuberculosis. Hence, the development of primary hepatic tuberculoma as a single liver mass is very unusual. In the present report, we describe the case of a 63-year-old man with a solitary hepatic tuberculoma; the 6.4 cm mass was incidentally detected during abdominal computed tomography in the asymptomatic patient, and the diagnosis was confirmed by liver biopsy through ultrasonography-guided fine-needle aspiration.
