Pulmonary giant cell carcinoma is one of the most highly malignant neoplasms of the lung. Although mixed malignant glandular or squamous components may be associated with a giant cell carcinoma, it is a distinct clinical and morphologic entity. We reviewed cytologic presentations of 6 cases of pulmonary giant ceil carcinoma. Cytologically, the single most characteristic feature of giant cell carcinoma was an extremely large, bizarre cancer cell engulfing numerous leukocytes. The nuclei of these cells showed occasional prominent nucleoli, and the cytoplasm was abundant. Giant cells were also seen in other types of pulmonary carcinoma, but the slant cells of this neoplasm could be differentiated from those encountered in undifferentiated large cell carcinoma and squamous cell carcinoma by the abundant cytoplasm, the presence of markedly enlarged nuclei, prominent nucleoli, and a significant degree of phagocytosis. In conclusion, precise diagnosis and classification of lung cancer is imperative because of proved correlation between cell type and prognosis.

The cytological and ultrastructural findings of Pneumocystis carinii(PC) obtained from rats by bronchoalveolar lavage (BAL) are described. All developmental forms of the PC organisms were obtained in the lavage fluid. Papanicolaou stain revealed conglomeration of PC as a foamy cast. The cystic walls of PC were well identified on Gomori's methenamine silver stain. Trophozoites and intracystic bodies were stained by Giemsa and Diff-Quik techniques. Some PC organisms were seen within the alveolar macrophages. Ultrastructurally, the cysts were almost circular in shape, and were nearly devoid of surface tubular extensions. The wall of the cyst was composed of an unit membrane, an intermediate electron lucent layer and an external electron dense layer The cysts frequently contained intracystic bodies, so called sporozoites. Occasionally empty or collapsed cysts with no intracystic bodies, and precysts were found. Trophozoites were variable in size and shape with abundant tubular extensions along the single electron dense pellicle. BAL is a useful method for concentrating the various morphologic forms of PC organisms, and is a rapid diagnostic method for PC pneumonia.

This is a clinical and retropective study on th patients with oral and maxillofacial trauma. This study was based on a series of 917 patients were treated as in-patients, at Chon-buk National University Hospital, during the period of Jan., 1989 through Dec., 1993. The results obtained were as follows : 1. The ratio of men to women were 3.59 : 1 in oral and maxillofacial injuries, 3.92 : 1 in facial bone fractures, and 3.18 : 1 in soft tissue injuries. 2. The oral and maxillofacial injuries occurred most frequently in the third decade(32.2%), and fourth, second, fifth decade in orders. 3. The major etiologic factors were traffic accident(57.4%) and fall-down(17.1%), interpersonal accident(16.6%), and industrial accident were next in order of frequency. 4. The incidence of facial bone fracture was 72.1%, soft tissue injury 58.8%, and dental injury 40.5%. 5. The most common site of fracture were mandible(62.9%) and maxilla(19.9%), zygoma and zygomatic arch(18.7%), and nasal bone(4.7%) were next in order of frequency. 6. The most common type of soft tissue injury was laceration(51.0%). The lesion of soft tissue injuries were mostly 1 or 2 lesions and deep.

By recent studies, HAP implant showed biocompatibility with host tissue, in that no toxic or foreign body reaction was found. HAP was known to have osteophilic property but not osteogenetic ability. This study examined the healing process on histologic basis following implantation with HAP-PCBM mixture on the inferior border of rabbit mandible. The results were as follws: 1. Mild inflammatory response was observed at 1st week, foreign body reaction and inflammatory response were not observed after 2nd week. 2. Osteoclastic, phagocytic activity was observed prominently on the grafted bone at 1st, 2nd week. 3. New bone was bonded with HAP particles directly without intervening tissue after 4th week. 4. At 8th, 12th week, mature bone was observed to have infiltrated between the HAP particles and osteoclastic activities were not noted. 5. Bony bridge between underlying cortical bone and HAP particles was observed after 4th week.

Dentinogenesis imperfecta is an autosomal dominant genetic defect which affect one patient in 6000 to 8000, also reported as hereditary opalescent dentin, or Capdepont dysplasia, in France. Clinically, the teeth are described as opalescent and acquire a distinct yellow-brown color shortly after eruption. The enamel chips away and the dentin which is apparently hypomineralized, is soon worn down. Radiographically, the roots appear shorter than usual and constricted to a variable degree in the cervical region and the pulp chambers are seen to be obliterated by the formation of further calcified material. The patient, a 16-year-old girl, was referred to the Dental clinic of the Chon Buk National University Hospital for discoloration of entire teeth and serious dental carious problem. Clinical appearance and radiographic examination revealed the typical abnormilities associated with dentinogenesis imperfecta and her two sisters and two brothers had same abnormalities. We performed extraction on severe cariou, teeth, intra oral sagittal split osteotony due to asymmetry and cross bite, also, rehabilated masticatory systems with fixed crown and bridge. We had a good result.
