Abstract

In the present study, new MRI techniques were used to evaluated the pathologic condition of a mucosal cyst in the maxillary sinus. The contrast enhancement technique using Gd-DTPA clearly revealed the cystic nature of the lesion. The diagnostic information about the relationship between the mucosal cyst and periodontal disease, and the precise location of the cyst in relation to the walls of the maxillary sinus were obtained by panoramic MR image and alternate positioning of the patient.

Abstract

Six cases of solitary (simple) bone cyst with typical clinical, radiographical, and histological findings were examined by bone scintigraphy. Bone scintigraphy using99mTc-HMDP was performed prior to operation. No uptake of99mTc-HMDP in these solitary bone cysts was demonstrated.

Abstract

The authors present examples of the significantly improved diagnostic imaging for cystic lesions in the jaw bone, floor of the mouth and maxillary sinus with Gadolinium-DTPA (Gd-DTPA) enhanced MRI. Twelve cases of cystic lesions, which were 6 cases of intra-osseous odontogenic cysts and cystic tumors, 2 cases of epidermoid cysts in the floor of the mouth and 4 cases of cystic polyp of the maxillary sinus. Improved MR images provided useful information delineating the thickness of circumscribed soft tissue wall (cystic wall), the location of the intra-cystic substance and the configuration of the tumor masses.

Abstract

The combined action of cadmium and X-rays was examined on 8-day mouse embryos using a whole embryo culture system. B6C3F1 mouse embryos were explanted onto the headfold stage and cultured for 40 hrs. To examine the dose-effect relationships of the single treatments, the embryos were exposed to 1.2−2.2 μM cadmium or to 0.82−2.64 Gy of X-rays at 1 hr. after the explantation. In combined treatments, 1.58 μM of cadmium was applied at 1 hr. and X-rays of 0.82 or 1.24 Gy was applied at 1.5 hr. The end-points measured were the yolk sac diameter, crown-rump and head lengths, somite number, protein contents of yolk sac and embryo, and formation of the neural tube defect. Cadmium-induced neural tube defect increased as a function of dose in a highly curvilinear manner. The remaining end-points affected by the single treatments were also indicative to be curvilinear. The combined action of cadmium and X-rays was found to exert an additive effect on the inhibition of embryonic growth and a synergistic effect on the teratogenicity. The form of the dose-effect curves of the single agents was suggested to be responsible for teratogenic synergism. Other possibilities of interaction remain to be resolved.
