Lymphomatous involvement of the gallbladder is rarely identified and manifests mostly as a local involvement of disseminated disease. There have been reported only about 20 primary malignant lymphomas of the gallbladder without involvement of other sites. A 63-year-old woman presented with jaundice, epigastric pain, and weight olss of two months duration. There was no systemic lymphadenopathy elsewhere. Abdominal computed tomograph revealed a focal thickening of the gallbladder wall. The removed gallbladder contained a well circumscribed, 5x3 cm-sized, slightly elevated firm area with accentuated mucosal papillary excrescences near the neck protion. The lesion involved whole thickness of the wall, and was made up of diffuse atypical lymphoid cell infiltrates of variable size accompanying plasmacytoid differentiation in areas. Some large tumor cells were pleomorphic and contained prominent nucleoli. To our knowledge, this is the first case of primary malignant lymphoma of the gallbladder in Korean literature.

The cranial CT is a new radiological technique with which, for the first time, minimal differences anattenuation by intracranial soft tissue can be measured exactly. Th basic physical principles of CT have beenextensively presented by Hounsfield (1973). It is well established that the attenuation of extravasated blood measures between 35 and 45 houns field units. Therefore no difficulty should be encoutered in the recognition anddiagnosis of extra-axial hematoma and cerebral contusion since the density of the brain parenchyma never measures more than 25 units. As the constant increase in high velocity accidents and violence, the problem of acute headinjury is one of the matters of great importance in today's medical practice. Therfore it is very important to figure out the method that would allow us to diagnose easily and precisely the effects of trauma upon the brain inorder to institute the proper treatment at the earliest possible moment . CT allows us to make a diagnosis quickly and in a non-invasive manner. The CT scan was carried out on 310 head trauma cases in the department of radiology, St. Mary's and Kang Nam St. Mary's Hospital, Catholic Medical College, for 16 months from June 1979 to Oct. 1980.All the scans were obtained with the Hitachi CT-H2 scanner and the scans were repeated following intravenous injection of high dose of contrast media(roughly 1.8cc per kg body weight of 60% Conray). We have reviewed the CTscans of 310 patients got acute head injury in order to assess the location of brain lesions, the relationshipbetween the CT scans of 310 patients got acute head injury in order to assess the location of brain lesions, the relationship between the CT densities of hematomas and their stage, the shape mass effect of the extra-axialhematomas, and the effect of contrast enhancement. The resuls were as follows; 1. Of all 310 cases of the headinjuries, epidural hematoma was 13.5%, subdural hematoma was 8.7%, subdural hygroma was 10%, cerebral contusion was 39%. hydrocephalus and atrophy was 3.9% and negative finding was 24.9%. 2. The extra-axial hematoma waslocated on the right side in 49.3% and the left side in 39.1% and bilaterally in 11.6%. Therfore unilateral lesion was much more than bilateral one. 3. The extra-axial hematoma was getting decreased in density as time gone by. 4. The shape of epidural hematoma was biconvex in 88.1% and planoconvex in 11.9%. 5. The shape of subdural hematoma was crescent in 88.9% and biconvex in 11.9% in chronic stage. 6. The mass effect of extra-axial hematoma was getting slowly decreased as time gone by. 7. The extra-axial hematoma was enhanced by the contrast media in allacute, subacute and chronic stages as well as in the cerebral contusion, but there was a tedency that the contrast enhancement of hematoma was getting increased as time gone by.

PURPOSE: We aimed to analyze the clinical features of herpetic endotheliitis and to investigate the risk factors for recurrence of herpetic endotheliitis and corneal decompensation. METHODS: The medical records of 58 patients (58 eyes) who were diagnosed with herpetic endotheliitis were retrospectively reviewed. Patients with a follow-up period of less than 6 months and a previous history of ocular inflammation were excluded from this study. We recorded visual acuity, intraocular pressure, central corneal thickness, and endothelial cell density on both initial and final visit, and recorded clinical findings of the anterior and posterior segments of the eye only on initial visit. Factors affecting the recurrence of herpetic endotheliitis and corneal decompensation were also analyzed. RESULTS: Among the 58 patients, 45 patients had disciform type endotheliitis, 11 patients had diffuse type, and 2 patients had linear type. There were no significant differences between final clinical manifestations according to subtype. 14 patients exhibited recurrence of herpetic endotheliitis. High intraocular pressure and high-grade anterior chamber cells were associated with the recurrence of herpetic endotheliitis. On multivariate analysis, the only risk factor for the recurrence of herpetic endotheliitis was high intraocular pressure. We found that 8 patients exhibited corneal decompensation, and high intraocular pressure, high anterior chamber cell grade, and a history of cataract surgery were associated with corneal decompensation. On multivariate analysis, the risk factors for corneal decompensation were high anterior chamber cell grade and cataract surgery history. CONCLUSIONS: For herpetic endotheliitis, the subtype did not affect the final records of clinical manifestation, and the only risk factor for the recurrence of herpetic endotheliitis was high intraocular pressure. Additionally, the risk factors of corneal decompensation were found to be high-grade anterior chamber cells and a history of cataract surgery. Initial examinations of clinical manifestation are important for the successful treatment of herpetic endotheliitis.

Argon laser trabeculoplasty(ALT) is commonly used in the treatment of uncontrolled open angle glaucoma. The authors retrospectively reviewed the efficacy of ALT in 52 patients(57 eyes) with primary open angle glaucoma. The mean follow-up was 28 months(range 2-48 months). The decrease in intraocular pressure 10P) was 10.1 +/- 3.5 mmHg at 1 month, 8.2 +/- 2.8 mmHg at 1 year, 6.2 +/- 5.1 mmHg at 2 years and 51% at 3 years. Failure was most common in the first 6 months after treatment(29%) and thereafter failure occurred at a rate of 5% to 15% per year. The sex and age of patients had no significant effect on success rate. The success rate was high in the patients with baseline IOP of 26 to 30 mmHg. A mild iritis in all cases, transient rise in IOP, peripheral anterior synechia and microscopic hyphema were noted as early complications of ALT.

Cutaneous manifestations of sarcoidosis are highly variable and can be devided into the specific lesions which reveal noncaseating granuloma and the nonspecific lesio is which are referred to as cutaneous changes. Among speciific lesions, annular lesions may be foimied from coalescing papular lesions that may clear centrally and elevate peripherally. We report a case of sarcoidosis with multiple annular lesions on the face in a 33-year-old female who had systemic involvements in the intrathoracic organs and eyes. The main histopathologir. findings were well-demarcated islands of epitheloid cells with a few giant cells in the dermis. In addition, a slight admixfure of lymphoid cells was present at the margins of the epitheloid cell granulomas. Complete regression of t!he skin lesions was obtained with systemic cortiocosteroid therapy and no recurrence has been found for 2 1/2years.

BACKGROUND: Glutathione S-transferase(GST) is a family of isoenzymes that play an important role in protecting cells from cytotoxic and carcinogenic agents. Strong activities of GST-Pi in the epithelial tissues was observed in the upper layer of skin, gastrointestinal tract and placenta which have been exposed to exogenous chemicals. OBJECTIVE: This study was done to observe the distribution pattern of GST-Pi in normal, acute and chronic psoriasis or eczematous dermatitis, using paraffin-embedded human skin tissues. METHODS: Twenty-one psoriatic and twenty-six eczematous dermatitis specimens were observed by immunohistochemical staining using an anti-rabbit GST-Pi polyclonal antibody. RESULTS: Stainining reaction for the GST is weakly to moderately stained in the normal epidermis. In the acute stage, upper layer shows weak and moderate staining in the lower epidermis of the psoriasis and eczematous dermatitis but in the chronic stage GST-Pi are noted strongly expression in upper epidermis. CONCLUSION: Immunohistochemical staining for the GST-Pi reveals a more abundant distribution in the chronic stage rather than in the acute stage of psoriasis and eczema tous dermatitis, showing no disease specificity. Therefore it is suggested that the detoxifying capacity decreases in the acute stage of above dermatosis.

Kaposi's sarcoma is a neoplasm of multifocal origin which manifest primarily as vascular nodules in the skin and other organs. We report a case of Kaposis sarcoma of classic type in a 17-year-old boy, who had a 4 x 5cm sized, dusky erythematous plaque with multiple spots of acupuncture on the left foot for 1 year. Histopathologic examination showed dilated, bizarre-shaped vessels, ndothelial cell proliferation, and spindle cell formation with vascular slits throughout the dermis. He was treated with 3000 rads of radiation(300 rad per day for l0 successive days). Six months after radiotherapy, gross findings were much improved and histopathologic findings showed only fibrosismc hemosiderin deposits in the dermis.

OBJECTIVE: In a pregnant rabbit model using hysteroscopy-guided inoculation of E. coli, we investigated pregnancy outcome according to elapsing time with immediate antibiotic treatment after E. coli inoculation, and in turn determined which of the maintenance of pregnancy with antibiotic and tocolytic administration or prompt delivery in the management of preterm labor complicated with intrauterine infection offered the improvement of pregnancy outcome. METHODS: Timed-pregnant rabbits underwent hysteroscopy at 20-21 days of gestation(70%). Animals were inoculated with either E. coli(0.2 ml containing 10' cfu/ml) or saline, and administered ampicillin-sulbactam(100 mg/kg/day; Unasyn; Pfizer) in divided doses every 8 hours beginning 30 minutes after microbial inoculation until euthanasia with one of the following; 3 days(n 10), 5 days(n 8), or 7 days(n-8) after hysteroscopy. In the first study, which performed in animals with inoculation of E. coli, pregnancy outcome including fetal survival rate and results of microbial studies and placental pathology were compared among three groups. In second study, which performed in animals with inoculation with saline, pregnancy outcome were compared among three groups for the purpose of elucidating effects of antibiotic administration during inoculation-to-euthanasia interval on pregnancy outcome. RESULTS: Of rabbits inoculated with E. coli and receiving antibiotics immediately, the rate of fetal survival and positive intrauterine cultures in total and live fetuses decreased significantly, and the rate of placental inflammation in total and live fetuses increased significantly with time from intracervical inoculation with E. coli to euthanasia(p<0.05, respectively). Of rabbits inoculated with saline and receiving antibiotics immediately, the rates of fetal survival, positive intrauterine cultures in total and live fetuses, and placental inflammation in total and live fetuses have no difference with time from intracervical inoculation with saline to euthanasia. CONCLUSION: Fetal complications including fetal death could be induced in utero if persistent subclinical intrauterine infection was present in spite of earlier antibiotics administration initiated after inoculation of E, coli. Therefore, when treating with antibiotics in intrauterine infection, it is needed to observe and monitor the presence of persistent intrauterine infection, and if it is persistent, prompt delivery may be better than maintenance of pregnancy with antibiotic and tocolytic administration for the improvement of pregnancy outcome.
