The traumatic retinopathy of Purtcher, traumatic liporrhagia retinae or traumatic retinal angiopathy, which has long been known to follow accidents, which is supposed to be caused by fat embolism due to particularly those involving extensive crushing or fractures in various part of the body, not from direct injuries of the eye. Ophthalmological reports on such conditions are rare. Recently we experienced a case of Purtscher's disease in which 52 year old male patient was first admitted in orthopedic department with anterior iliac crest bone fracture, left 6th-7th ribs fractures and pneumo thorax by being pinned down under about 2 tons weights at a casting factory, Accordingly, we report here a case of traumatic retinopathy of Purtcher with literature.

Balancing the rates of cell proliferation and cell death is important in maintaining normal tissue homeostasis. The relationship among apoptosis, cell proliferation and factors influencing apoptosis according to the histologic types in chemically induced mammary tumorigenesis appears important in understanding the pathogenesis of breast carcinoma. In this study, we investigated alterations in the kinetics of cell proliferation and apoptosis during rat mammary tumorigenesis induced by 7, 12-dimethylbenzanthracene (DMBA) and we related these changes to the expressions of bcl-2, p53, and TGF-beta. Seven-week-old female Sprague-Dawley rats were divided into an experimental group (20 mg/ml DMBA by oral intubation) and a control group. The results were as follows. 1. In the experimental group, breast tumors occurred in twenty two of fifty nine rats(37.3%, 22/59), and the total number of tumors was 100 (4.5 2.0/rat). The histological classification was infiltrating ductal carcinomas (n=5), ductal carcinomas with focal invasion (n=10), intraductal carcinomas (n=36), adenomas accompanied with intraductal proliferation (n=35), intraductal proliferation (n=9), and adenomas (n=5); 2. The differentiation of terminal end bud into alveolar bud (AB) in the experimental group was significantly lower than that of the control group (p<0.05); 3. BrdU labeled tumor cells were mainly located at the peripheral portion of tumor cell nests. BrdU labeling indices were highest in ductal carcinomas, less pronounced in intraductal proliferation, and lowest in adenomas, whereas apoptosis levels were highest in adenomas, less pronounced in intraductal proliferation, and lowest in ductal carcinomas (p<0.05); 4. p53 protein was not expressed in any breast tumors. Although the expression of bcl-2 protein was highest in infiltrating and focal infiltrative ductal carcinomas (58.3%), compared with adenomas, intraductal proliferation, and intraductal carcinomas (p<0.05), the extent of its expression was less than 1% of all tumor cells; 5. TGF-beta was mainly expressed in the central portion of tumor cell nests rather than in peripheral portion, and TGF-beta immunoreactive tumor cells displayed good differentiation and did not reveal BrdU immunoreactivity. TGF-beta labeling index of infiltrating and focal infiltrative ductal carcinomas was significantly higher than that of intraductal carcinomas, intraductal proliferation, and adenomas (p<0.05). Based on these results, it is thought that high cell proliferation and the suppression of apoptosis are closely associated with DMBA-induced rat mammary carcinogenesis. However, the suppression of apoptosis is not related to p53 mutation, bcl-2, and TGF-beta. TGF-beta seems to be reversely related to tumor cell proliferation but closely associated with the progression of the tumor, especially an invasion of breast carcinomas.

Neoplasms showing both carcinomatous and sarcomatous features are well established, and have been reported in practically every organ where carcinoma can occur. But the difference in terminology and difficulties in histopathologic interpretation have hampered adequate understanding of these neoplasms. We report a case of carcinosarcoma in the recurrent form of serous cystadenocarcinoma of the ovary. The patient was a 64-year-old female who underwent total hysterectomy and bilateral salpingoophorectomy three years ago, due to perforated papillary serous cysta denocarcinoma of the right ovary. Recurrent pelvic masses contained both carcinomatous and sarcomatous components. Morphological transition between carcinomatous and sarcomatous components, and epithelial characteristics in the sarcomatous component by immunohistochemistry were recognized. We postulate the histopathogenetic mechanism based on the phenotypic conversion of carcinoma into sarcoma in the carcinosarcoma.

A case of an ovarian mucinous cystadenocarcinoma with mural nodules of anaplastic carcinoma is reported. The patient was a 46-year-old female with a right ovarian cystic mass and underwent a total abdominal hysterectomy with bilateral salpingo-oophorectomy. The patient died of the disease in five months. Macroscopically, the right ovarian cyst wall contained numerous well-demarcated mural nodules. Histologically, the cysts were mucinous cystadenocarcinoma, and the nodules were composed of sarcoma-like spindle and polygonal cells with atypia and numerous mitoses. Spindle cells in the mural nodule showed epithelial characteristics by electron microscopy and immunohistochemistry. This case supports an epithelial origin of the mural nodule of anaplastic carcinoma in ovarian mucinous tumors.

The spondylolysis is a defective ossification in the pars interarticularis of the neural arches without displacement of the vertebral body. The authors analysed 810 lumbar spines of adult Korean laborers on the basis examined to determine the anatomic characteristics of spondylolysis. The following results were obtained. 1. The overall incidence in laborer was 6.8%. 2. The most frequent site of the involvement was the fifth lumbar vertebra. of radiologic study and 3. Spina bifida in spodylolysis was approximately 1.7 times as frequent as is normally expected. 4. Lumbarization in spondylolysis was approximately 5.8 times as frequent as is normally expected. 5. Sacralization was not found in 55 cases of spondylolysis.
