The pulmonary microvasculatures of rats were studied by injection replicas prepared from Mercox. This medium enabled us to easily obtain consistent, stable, and complete injected replicas of the pulmonary vasculature. In order to investigate the three dimensional structures of the tributaries of the bronchial artery, such as the capillary plexus and vasa vasorum, we performed a scanning electron microscopic(SEM) study of the vascular casts, using Mercox CL-2B as a media. The alveolar capillaries revealed hexagonal or pentagonal rings of vascular networks. In some areas, the vascular rings composed a square network, The bronchial tree was supplied by the bronchial arteries which form a coarse capillary extending as far as the terminal bronchioles. Occasionally the capillary plexus was connected with adjacent capillary networks in and around the alveolar walls. The walls of the pulmonary artery revealed only a single layer of the vasa vasorum, but those of the pulmonary vein were surrounded by more complicated and well developed vasa vasorum than the pulmonary arterial side. The mean diameters of the venous vasa vasorum are greater than the arterial vasa vasorum.

Gastritis cystica profunda (GCP) is an uncommom hyperplastic lesion, which is located within the submucosa. GCP may occur several years after previous gastric surgery. In some reported cases, it was a premalignant condition and may lead to carcinoma of the stomach. We report a case of a 54-year-old man with epigastric pain and dyspepsia. He had undergone peritoneal dialysis for end stage renal disease about 13 years prior. An Upper gastrointestinal endoscopy showed elevated lesion at the gastric antrum, looking like an advanced gastric cancer or gastrointestinal stromal tumor. Endoscopic biopsy results were tubular adenoma with low-grade dysplasia. When followed up 9 months later, the lesion had increased in size and symptoms remained. We therefore performed a subtotal gastrectomy. The final biopsy was adenocarcinoma arising in GCP.

This study was carried out to investigate the mechanisms of interstitial pulmonary fibrosis of rats after the intratracheal administration of bleomycin. Both lungs after bleomycin injection were examined by light and electron microscopy. The results are as follows: Light microscopically, 1 or 2 weeks after bleomycin injection acute and chronic inflammatory infiltrates and edema in the interstitium and alveolar spaces were observed. Proliferation of alveolar type II pneumocytes was also found at 4 to 6 weeks after bleomycin injection, chronic inflammatory infiltrates with interstitial fibrous thickening were noted. Electron microscopically, the number of type II pneumocytes and irregular lamellar bodies were increased and blunted microvilli were noted at 2 weeks. 4 to 8 weeks, proliferation of fibroblasts with deposition of abundant collagen fibrils in the thickened interstitium revealing irregular or collapsed alveolar spaces were observed. Based on these findings, it can be concluded that bleomycin-induced interstitial pulmonary fibrosis is considered to pass from an early acute inflammation of the interstitium and alveolar spaces to an interstitial fibroblast proliferation and collagen deposition to the length of the period after injection.

This study was carried out to investigate the morphologic characteristics and localization of antigenic molecules of Pneumocystis carinii in experimentally induced P. carinii pneumonia in rats. After six weeks of administration of low protein diet and dexamethasone, Sprague-Dawley rats were sacrificed to submit lungs or bronchoalveolar lavage for the study. Monoclonal (092, 900, 902, and 904) and polyclonal (SP-D) antibodies were used for immunohistochemistry and immunoelectron microscopy (ITEM and ISEM). Immunohistochemically P. carinii organisms were well identified as clusters or separated forms in the alveolar spaces being frequently attached to the alveolar walls. Immunoelectron microscopically the adherences of gold particles were observed on the surface of all stages of the P. carinii. Occasionally positive immunogold labeling was observed in the cytoplasm of the trophozoites and on the pellicle of the intracystic bodies within the cysts. The monoclonal antibodies 092, 900, 902, and 904 reacted mainly with pellicles of P. carinii, whereas SP-D labeled on the pellicles, intracystic bodies, cytoplasms of the alveolar macrophages, and free floated surfactant material in the alveolar spaces. The immunogold particles were observed more diffusely and intensely in the cysts than in the trophozoites. These results indicate that antigen is mainly localized on the pellicles, and accumulated during development from the trophozoite to the cyst stages.

Stasis dermatitis is one of the important skin manifestations of venous stasis. Therefore, the searching for the cause of venous stasis is importrnt. Two cases of stasis dermatitis with inferior vena caval obstruction are reported and possible etiologic factor is discussed. Case I The patient, 38-year-old carpenter, was admitted at Choong Buk Medical Center in April, 1974 with superficial venous engorgement of the lower extremities which had begun to appear two years after severe blunt trauma to both legs in 1962. 5 years prior to admission, abdomial venous engorgement and abdominal fullness developed and was exaggerated gradually. Since 2 years prior to admission, he has been suffered from the recurrent exudative ulcer on the right lower leg The physical examination revealed mild icteric sclera, hepatomegaly, abdominal distension, tortuous venous engorgement on the abdomen, the lateral chest wall and the lower extremities, and edematous scaly brawny pigmentation of the lower legs. Esphagogram showed no esphageal varices. Inferior vena cavogram showed complete obstruction at the level of upper border of 2nd lumbar vertebra and well developed collateral circulation, Findings of skin biopsy on the right lower leg showed moderate acanthosis, increased pigmentation of bosal cell layer in the epidermis, capillary proliferation, diffuse inflammatory cell infiltration with increased fibrosis and hemosiderin granules in the dermis. Case II The patient. 36-year-old farmer, was admitted at Dept. of Dermatology, St. Mary's Hospital, Catholic Medical College in Sept., 1973.The physical examination revealed hepatomegaly, abdominal distension, superficial venous engorgement on the abdomen, the neck and the lower extrcmities, severe edema and pigmentation of the lower legs, and the multiplc. Exudative ulcers on the left lower leg. Liver scanning showed somewhat general enlargement with some mottlings along the margin and relative prominance of the left lobe. Liver biopsy revealed findings of non specific chrcnic hepatitis. Inferior vena cavogram through the left femoral vein showed complete obstruction at the level between 11th and 12th thoracic vertebrae.His peripheral edema and ascites was much subsided after adequate bed rest and the skin lesion improved with scar formation.

To identify significant prognostic factors in patients undergoing simple hysterectomy in the presence of invasive cervical cancer, the records of 45 patients who had taken such a procedure between 1993 and 1997 were reviewed. Overall relapse-free survival and 5-year survival rates were 91.1 and 92.1%, respectively. Factors found to be significantly related to survival were the retrospectively determined stage(p=0.0000), the presence of residual disease(p=0.0001), and cell type(p=0.0000). By multivariate analysis, factor emerging as significantly detrimental to survival was the cell type. The presence of residual disease was a marginally significant factor(p=0.067). The expectations for survival of patients with residual tumor mass and/or with adenocarcinoma after simple hysterectomy appear to be markedly worse than those with others, so radical reoperation should be considered in those patients.
