The pathologic features of acute corrosive esophago-gastritis by ingestion of "Trapunc", a common commercial drain cleansing liquid, is presented. A 37-year-old woman ingested abut 30 ml of Trapunc (3 gm NaOH/100 ml) to commit suicide and received piecemeal esophagectomy and total gastrectomy 9 days after the episode. The esophagus and stomach were extremely friable and necrotic. The most part of the stomach showed acute toxic necrotizing gastritis which was manifested by extensive greenish brown discoloration due to liquefaction necrosis of the mucosa except for a few rugae along the greater curvature. The antrum and distal body revealed severe mucosal detachment and even transmural necrosis. The tissue reaction was basically the same as those of NaOH-induced corrosive esophago-gastritis of acute stage, although it appeared to be severer probably due to sodium hypochlorite, and additive constituent of the ingested cleanser. A unique distribution pattenr of mucosal involvement is discussed.

The functional and morphologic cardiac developments are determined by the morphogenesis, growth and remodeling of the heart resulted from the cell proliferation and apoptosis. We studied the distribution of the proliferation and apoptotic activity of myocardial cells according to the developmental stages in embryos of C57bl/6 mice. Serial histologic sections were stained with PCNA and TUNEL method and were analyzed with image analyzer (BMI, Seoul). The ventricular myocardium of an embryonic heart could be divided into trabecular, inner compact and outer compact layers. Proliferation indices at layers of the left ventricular myocardium on embryonal days (ED) 13, 14, 16, 17 and 18 were 19.9%/47.4%/60.4%, 16.1%/45.8%/60.3%, 24.6%/45.6%/38.1%, 23.3%/17.7%/18.3% and 31.2%/28.0%/19.4% (trabecular/ inner compact/ outer compact) and the right ventricle, 11.0%/34.4%/60.5%, 23.0%/44.0%/69.0%, 29.2%/42.9%/35.1%, 30.4%/30.5%/22.3% and 32.4%/28.4%/16.3%. The apoptotic indices of the left ventricle/VIF were 0.23%/3.66% on ED 13-14, 0.42%/1.31% on ED 16 and 0.05%/0.60% on ED 17-18. The results show that the proliferation of the myocytes was maximal at the outer compact layer on ED 13 and 14 but lowest on ED 17 and 18. This decrease was more pronounced at the left ventricle. The innermost trabecular layer showed a constant proliferation activity of 11.0-32.4%. The presence of spatiotemporal differences in the cell proliferation reveals regional regulation in the developmental timing of cardiac development. Functional maturation is considered to be responsible for the change of proliferation activity. The apoptosis was most frequent and intense in the VIF and crux throughout the periods of each embryonal day where as rarely seen in the ventricular myocardium, especially in the trabecular layer of myocardium. These findings suggest that the apoptosis plays the role in the development of atrioventricular, ventriculoarterial septation and valve formation. Our results also reveal that the participation of apoptosis in formation of the trabeculation can be denied.

Polyamines are closely related to cell growth and differentiation and increased levels of urine polyamines (UPs) has been reported in various human cancers. However, there were few reports on changes of UPs in patients with cervical carcinoma. We investigated the clinical utility of UPs as well as serum squamous cell carcinoma (SCC) antigen in cervical carcinoma. The association of pretreatment SCC antigen and UPs with clinicopathologic parameters was assessed in 478 patients with cervical carcinoma. SCC antigen was measured by radioimmunoassay and UPs by enzymatic assay method. The prognostic significance of pretreatment SCC antigen and UPs, and the relationship between pretreatment and posttreatment SCC antigen and UPs according to treatment modalities were analyzed. There was a trend of increased level of UPs with cancer progression, whereas significant difference of SCC antigen value was found with cancer progression. Among various clinicopathologic parameters, tumor size and macroscopic lymph node metastasis were associated with pretreatment SCC antigen and UPs level as well. Increased pretreatment SCC antigen level (>2.0ng/ml) and UPs level (>45 micromol/g creatinine) had significant impact on survival. Multivariate analysis revealed that pretreatment SCC antigen, lymph node metastasis and tumor size were independent prognostic factors on survival in the same stage patients. SCC antigen levels decreased after radiotherapy and neoadjuvant chemotherapy. In patients treated by radiation, response status was associated with postradiation SCC antigen, which showed a good correlation with survivals. UPs positivity and SCC antigen positivity in 42 recurrent cervical cancers were 64.7% and 57.9%, respectively. Pretreatment SCC antigen, combination of SCC antigen and UPs, tumor size, macroscopic lymph node metastasis and invasion depth were correlated with recurrent or residual cervical carcinoma. In conclusion, UPs together with SCC antigen may be used to assess the extent of disease status and to define the prognosis in cervical carcinoma.

BACKGROUND: According to the 1992 version of ACLS guideline, adenosine is recommended as the first line drug far the treatment of paroxysmal supraventricular tachycardia(PSYT). But adenosine is not used frequently in our country, despite currency proven effect and safety. Therefore we tried to compare the efficacy and safety of adenosine with verapamil for the treatment far PSVT. MATERIALS AND METHODS: We prospectively reviewed charles of PSVT patients admitted to YongDong Severance Hospital from Jan. 1995 to Dec. 1996. These patients were randomly divided into two groups. The flat group was given 6mg of adenosine initially, and another 12mg was given within 5 minutes if fast dose failed. The other group was given 5mg of verapamil initially, and if failed, 10mg was given within 10 minutes. The results were analyzed by Chi-square test and student-t method. RESULTS: In converting PSVT to normal rhythm, adenosine and verapamil showed similar results and there was no difference between the two Groups in frequency of side elects, but serious arrhythmia such as ventricular fibrillation and ventricular tachycardia was not seen in the adenosine group. CONCLUSION: Adenosine not only showed comparable effect and safety, but also had shorter action time than verapamil. Therefore we recommand adenosine, as a safe and effective fort line drug for PSVT.
