Blue nevi commonly occur on the skin of head, neck, and arms, and in occasional instances they have been observed in the mucosa of oral cavity, vagina, hard palate, and even breast, and in very rarity observed in the uterine cervix. We have experienced a case of blue nevi on the uterine cervix of a 45 year old famale who was operated under the diagnosis of uterine myoma. In gross findings, besides two well circumscribed uterine myomas measuring 3.5 cm and 0.6 cm in diameter in the anterior myometrium, multiple pin-point sized grayish blue pigments measuring 2-3 mm in diameter aggregated in the submucosa of the uterine cervix. Microscopically the blue nevi showed greatly elongated, slender often slightly wavy melanocytes with long, occasionally branching dendritic processes lie grouped in irregular bundles in the submucosa of the uterine endocervix. The pigments showed positive response to the Fontana-Masson stain in the cytoplasm and the extracellular area.

The most important spinal disorders in childhood are malformations and mass lesions. High-resolution, real-time ultrasonography of the spine enables the differentation of intraand paraspinal structures in a significant way. This examination does not require sedation, does not use radiation, can be performed in the nursery or an incubator and is less expensive than computed tomography or magnetic resonance imaging. The sonographic appearence of the various kinds of spinal dysraphism is demonstrated and illustrated. Based on our preliminary experience spinal sonography appears to be useful in neonates and infants as the first imaging device for differentiation of cmplex malformation and as a screeing method for occult spinal dysraphism.

When a soft tissue mass in the bony wall of the paranasal sinus is present, it is difficult to make a distinction between tumor and inflammatory mass on CT. Fungal sinusitis may have soft tissue attenuation on the bony wall of the sinus, bony sclerosis, focal bony destruction, and calcific area on CT. This is a report of four proven cases of fungal sinusitis, asperogillosis in 3 cases and mucormycosis in 1 case, All 4 patients had CT and one patient had MRI, On CT, bony sclerosis and destruction were well visualized in all cases. On MRI, mycetoma in the maxillary sinus was hypointense on T1 weighted images and more hypointense on T2 weighted images. Although CT appears to be the best modality for initial examination of the patient with sinusitis, the differentiation of fungal sinusitis from tumor mass or other entity may be better accomplished with MRI.

In order to elucidate the biological effects of pulsating magnetic field in in vitro culture system we designed a pulsating magnetic apparatus using 120 Hertz, 24 Volt direct current. It can generate 63~225 Gauss in the experimental area of 90 mm petri dish, and has little thermal effect on the culture media in 37.5oC, 5% CO2. Human osteogenic sarcoma (HOS) cells were cultured in the pulsating magnetic field and the nuclear changes of cultured cells were observed routinely by hematoxylin staining, and apoptotic change was detected by ApopTag staining using both peroxidase and fluorescein labelings. Compared to the control group which formed well organized whorling pattern of HOS cell line in 3 days culture, the HOS cells cultured in the pulsating magnetic field for 12 hours or 24 hours grew irregularly and showed increased number of apoptotic cells. When the flow of pulsating magnetic field was interrupted by insertion of strong permanent magnetic bar (1000 Gauss, 5530 mm) beneath the petri dish during in vitro culture, the area of sparse pulsating magnetic field showed active proliferation and aggregation of HOS cells even in 24 hour exposure group. These data suggest that the pulsating magnetic field may play a role in inducing growth retardation and apoptosis of HOS cells. Furthermore, the hazardous effects of pulsating magnetic field can be lessened or nullified by the interruption of pulsating magnetic field with a strong permanent magnetic bar.
