Choriocarcinoma of the gastrointestinal tract is rare. Among them, that of the stomach is the most common. Six cases of choriocarcinoma of the colon were found in the review of the literature. All of these previously reported cases had multiple metastatic foci in the liver, lung, lymph nodes and the prognosis seemed to be very poor. Therefore we think that choriocarcinoma of the colon should be distinguished from conventional adenocarcinoma. A 66-year old female patient, described in this case, was operated on under the impression she was suffering from acute appendicitis. The resected ascending colon revealed extensive hemorrhagic necrosis and perforation with fibrous adhesion in the cecum. On the cut section, the mural tumorous thickening was not definite. Histologically, the tumor showed a focus of typical adenocarcinoma arising from glandular epithelial cells, which were transformed into highly anaplastic tumor cells. There were frequent vascular invasions of tumor cells, similar to syncytiotrophoblasts. In the immunohistochemical stains, both glandular and highly anaplastic tumor cells reacted with cytokeratin. The glandular cells were also reactive for carcinoembryonic antigen (CEA) and anaplastic tumor cells for human chorionic gonadotrophin (hCG). This is the first report of choriocarcinoma of the colon in Korea. We describe this case with a review of the literature.

We herein report a case of transient acrodermatitis enteropathica in a 3-month-old, breast-fed, full-term infant. The patient was presented with a 2-month history of diarrhea and crusted erythema- tous patches on the periorificial area. Similar lesions were seen in his siblings. His serum zinc level and the zinc level in his mother's breast milk were markedly reduced. Diarrhea and skin lesions disappeared promptly with oral zinc supplementation and did not recur when zinc was discontinued after three weeks. Our case indicates that even full-term infants, who feed excl-usively on mothers milk, run a risk of developing zinc deficiency, if the concentration of zinc in the breast milk is very low.

Authors experienced 100 cases of retrobulbar optic neuritis among the patients who visited the Chang Shoo Choi Eye Clinic during the last 2 years, from September 1, 1964 to August 31, 1966. The chief complaints are asthenopia, blurring vision, ocular pain, headache and photophobia. Of 100 cases, 46 cases wanted to be refracted. The corrected visual acuities are not always poor, though they are very variable from time to time as the tests are processing. The most cases revealed central relative scotomas instead of cecocentrals as previously believed. Fields are taken with glasses if corrected. In our cases, the age distribution of the patients are very interesting, the most susceptible age groups are 11~13 years.

The T cell responses to hepatitis B surface antigen (HBsAg) were analyzed in acute hepatitis patients, chronic active hepatitis (CAH) patients and asymptomatic carriers. Neither proliferative responses nor substantial cytokine production of peripheral blood mononuclear cells (PBMC) in response to HBsAg was detected. For further studies, HBsAg- reactive T cell lines were prepared from PBMC of the hepatitis patients and asymptomatic carriers. No proliferative response of the T cell lines was observed. Interestingly, however, T cell lines obtained from acute hepatitis patients were found to produce IFN-r, but not IL- 4, in response to HBsAg stimulation, whereas T cell lines obtained from CAH patients and carriers were not. Results of this study suggest that HBsAg-reactive T cells producing Thl type cytokines may play an important role in the viral clearance during acute infections, while defects in those T cells may be responsible for the viral persistency.

To investigate the effect of diazepam on the contractility of the intestinal smooth muscle, longitudinal muscle strip isolated from rat ileum was prepared for myography in isolated organ bath. 1) Basal tone of ileal muscle was reduced by diazepam concentration-dependently. 2) Higher concentrations (30 and 100 microM) of diazepam inhibited (p<0.05, p<0.001) The carbachol-induced contraction in a concentration-dependent manner; but lower concentration of diazepam (10 microM) enhanced (p<0.05). 3) Histamine-induced contraction was inhibited by pretreatment with diazepam in a concentration-dependent manner. 4) Ca⁺⁺-induced tension recovery in calcium-free solution was inhibited in the presence of diazepam concentration-dependently. These results suggest diazepam reduces the contractility of the longitudinal muscle isolated from rat ileum via interference with influx of calcium into the muscle cells.

Mitral valvular orifice area is important for the evaluation of prognosis and treatment of patients with mitral valvular stenosis. Until recently, Gorlin's formula using cardiac catheterization has been utilized in the measurement of mitral valve area, but it is invasive and impractical to examine repeatedly. Recently 2-Dimensional echocardiography appeared to be a practical and useful substitute in measurement of valve area and also it is economical and has no risk to patients. In 31 patients with mitral valvular stenosis examined at the echocardiography room of Busan national University Hospital from March 1982 to March 1983, we measured the mitral valve area with 2-Dimensional echocardiography and evaluated its relationship with the left ventricular functions measured on M-mode echocardiogram. Among many parameters on M-mode measurements EF slope, excursion amplitude and the ratio of left atrial dimension to aortic root dimension were rather helpful for the assessment of severity of mitral valvular stenosis than other parameters. And each relationship with the valve area showed correlation coefficient of 0.60, 0.05 and -0.58, respectively.
