Carcinoma of the uterine cervix is the most common malignant tumor in Korean women. It is well known that carcinogenesis is a multi-step event involoving the inactivation of tumor supressor genes, such as p53 gene and RB gene. The inactivation of the normal functions of the tumor-suppressor proteins pRB and p53 are important steps in human cervical carcinogenesis, either by mutation or from complex formation with the HPV E6 and E7 oncoproteins. The pRB protein regulates early cell cyle progression by controlling transit through the G1 phase of the cell cyle. The p53 tumor suppressor gene product also plays a role in cell cycle control by the transcriptional regulation of cyclin-CDK inhibitor. Cervical carcinoma is an excellent model for studying the stepwise progression of cell transformation because this is reflected morphologically by the increasing dysplasia of the squamous cells before it becomes and invasive squamous cell carcinoma. The aim of this study was to examine the expression of pRB and compared that with overexpression of p53 in a series of cervical lesions including normal tissuess, dysplasias, carcinoma in situ and carcinomas by immunohistochemical staining with monoclonal antibody to elucidate the role of these tumor suppressor genes. The result were as follows: 1. In normal cervical mucosa and CIN I , a few positively stained cells for pRB were seen in basal and parabasal layer. 2. An abnormality of pRB, loss of expression was seen in 23.8% of CIN III and in 10.8% of invasive carcinoma. 3. Overexpression of p53 was demonstrated in 14.3% of CIN III and in 59.5% of invasive carcinoma. 4. The immunoreactivity of p53 was significantly increased (p<0.05) in stage II, III than stage I , whereas downregulation of pRB and tumor stage was not correlated. 5. The immunoreactivity of p53 was significantly increased (p<0.05) in squamous cell carcinoma than in adenocarcinoma, adenosquamous carcinoma and CIN III. These result suggest that an alteration of pRB is more frequently implicated in CIN III than invasive carcinoma, whereas overexpression of p53 may be involevd in late progression of uterine cervical carcinoma.

OBJECTIVE: Because endometriosis is difficult to diagnose and has a high recurrence rate after treatment, a reliable serum marker of endometriosis is necessary. Therefore, the aim of this study is to measure the serum levels of CA125 and CA19-9 in patients with endometriosis before and after treatment and during recurrence, and to assess the usefulness of these levels in the diagnosis, clinical follow up and prediction of recurrence in endometriosis. METHODS: Eighty-eight patients who visited the department of Obstetrics and Gynecology of Ewha Mokdong Hospital from January 1994 to December 1998 and were diagnosed as endometriosis by laparoscopy or explo-laparotomy were enrolled as subjects. A retrospective analysis of serum CA125 and CA19-9 levels at 1 month before and 3 to 6 months after initiation of treatment was done. RESULTS: The serum CA125 and CA19-9 levels of endometriosis group(81.0+/-252.5, 36.6+/-53.4 ; mean+/-2SD, U/ml) before treatment was significantly higher than control group(11.6+/-12.8, 9.4+/-8.6)(p<0.05). Overall sensitivity rate for CA125, CA19-9 levels and both was 53.4%, 42.9% and 64.3% respectively. The sensitivity rate for endometriosis, stage 3 and 4(85.4%, 55.0%) was significantly higher than that, stage 1 and 2(p<0.05). The serum CA125 level in endometriosis group showed a significant increment according to stages(p<0.05) while the serum CA19-9 level showed an increasing trend(p=0.055) and both levels decreased significantly after treatment(p<0.05). The serum CA125 level was also higher at recurrence after treatment(p<0.05). CONCLUSIONS: The serum CA125 and CA19-9 levels are a useful marker for diagnosing severity of disease, monitoring efficacy of treatment and predicting recurrence in endometriosis.

OBJECTIVE: Diffusion tensor MR imaging (DTI) provides a means to visualize the course of the corticospinal tract within the white matter. The purpose of this study was to investigate the corticospinal tract in patients with deep intracerebral hemorrhage (ICH) involving the posterior limb of the internal capsule, to correlate with the motor impairment of the extremities, and to predict with motor improvement after stereotactic evacuation of the ICH. METHODS: Ten patients with deep intracerebral hemorrhage (ICH) on the basal ganglia or thalamic region were included to this study. All patients underwent the stereotactic catheter insertion. The DTI was obtained within 5 days after the hemorrhagic attack, focusing on the posterior limb of the internal capsule (PIC). The patients were evaluated using the motor grading system (grade 0 to 5) initially and 2 months later. The Mann-Whitney U test was used for the statistical analysis. RESULTS: The motor scales improved only in the patients with the partially or non-involved PIC. The p value was 0.007 for upper extremities and 0.008 for lower extremities. In patients with the totally preserved PIC, follow-up motor scales improved in comparison with the preoperative state. In patients with the partially preserved PIC, follow-up motor scales improved according to the hierarchical organization principles. CONCLUSION: The DTI can show the degree and locations of the involvement by the hemorrhages to PIC and the DTI may be used as a good indicator to the motor function outcome in the patients with hemorrhagic stroke at basal ganglia or thalamic region.

Necrolytic migratory erythema is a rare, distinctive, necrotizing cutaneous eruption usually associated with glucagonoma, an alpha-cell tumor of the pancreas. Other clinical features include ane- mia, diabetes mellitus and weight loss. However, it also occurrs without the pancreatic glucagonoma. So this rare condition is called pseudoglucagonoma syndrome, and has been described in association with chronic hepatic diseases, malabsorption with villous atrophy, chronic pancreatitis, celiac sprue, hypoproteinemia and odontogenic infection. We report a case of pseudoglucagonoma syndrome induced by malnutrition without glucagonoma. A 28-year-old Korean female was referred to our department complaining of multiple erythematous, desquamative, crusted and erosive patches on the extremities, and diffuse scalp alopecia for 5 years. She also had perianal erosion, angular cheilitis without glossitis, amenorrhea, axillary and pubic hair loss, and weight loss. Six years previously she had had Whipples operation for a pancreatic solid and papillary neoplasm. The laboratory data showed hypoalbuminemia, essential fatty acid deficiency, diabetes mellitus and slightly high levels of zinc and glucagon. A skin biopsy showed irregular acanthosis, epidermal edema and pallor, dyskeratosis, areas of superficial epidermal necrosis and vascular dilatation of the papillary dermis. The patient improved dramatically after intravenous hyperalimentation and oral intake of mediurn chain triglyceride. For 2.5 years she has taken medium-chain triglycerides without any other treatment, and no side effects on recurrence has been observed.
