The immunohistochemical expression of transforming growth factor-beta(TGF-beta), epidermal growth factor(EGF) and alpha-1-antitrypsin(AAT) was studied in 47cases of endoscopic biopsy matearials of gastric carcinoma to determine me correlation to the expression of alpha fetoprotein(AFP). And immunoreactivity of the antigens was correlated to me degree of tumor infiltrating lymphocytes and histologic differentiation of the tumors. And the results were analyzed to elucidate pathological AFP-producing gastric cancer. The results were summarized as follows. AFP immunoreactivity was demonstrated in 30 cases(63.8%) of the tumors, TGF-beta in 26 cases(55.3%), EGF in l4 cases(29.8%) and AAT in l0 cases(21.3%). The incidence of expression of the antigens was significantly higher in the cases of elevated serum AFP(>2ng/ml) than that of the cases with normal serum AFP(p<0.05). There was no relation between the expression of antigens and histological differentiation of gastric cancer. The expression of AFP and TGF-beta revealed good correlation(k=0.72). The relation between expression of TGF-beta and AAT and the degree of tumor infiltrating lymphocytes disclosed negative correlation(p<0.05). These results suggest that TGF-beta and AAT prodution contribute to the worse prognosis of AFP-producting gastric cancer. Possible immunosuppressive action of TGF-beta and AAT in the cancer tissue is discussed.

OBJECTIVE: The present study was undertaken to examine the effects of magnesium ion in the culture medium on the development of mouse fertilized oocytes either before or after pronuclear formation, and to investigate whether the effect of magnesium ion is related with the redistributional change of mitochondria. METHODS: Fertilized oocytes obtained from the oviducts of mice at 15 hr after hCG injection before pronuclear formation (pre-PN) or 21 hr after hCG injection after pronuclear formation (post-PN) were used. The embryos were cultured for 3 days with basic T6 medium-magnesium free and various concentrations of magnesium ion, 0.0, 0.5, 1.0, 2.0, 4.0 or 8.0 mM, respectively. After culture, the developmental stages of embryos and the number of nuclei were evaluated. To observe the effects of magnesium ion on the mitochondrial distribution, fertilized oocytes were collected at 21 hr after hCG injection and cultured for 6 hr with various concentration of magnesium ion. As a control, fertilized oocytes with pronuclei at 27 hr after hCG injection were used. RESULTS: The concentration of magnesium ion to accelerate the in vitro development of mouse fertilized oocytes appeared to be at 2.0 mM for the pre-PN and the post-PN stage embryos. In the mitochondrial redistribution patterns, the embryos cultured in 2.0 mM concentration of magnesium ion showed the highest percentage (22.6%) of distinct perinuclear clustering pattern comparing to other experimental group. CONCLUSION: The effect of magnesium ion may be related to the cytoplasmic redistribution of mitochondria. This relationship seems to connect the developmental competence of preimplantation mouse embryos in vitro. These results can suggest that higher concentration of magnesium ion (2.0 mM) than those of conventional culture medium (0.2~1.2 mM) is more suitable for in vitro culture of preimplantation mouse embryos.

Acute epiglottitis is an inflammatory process of supraglottic region, which involving the epiglottis andhypopharynx region. This disease can be recognized easily radiologically and virtually all death are preventable.The lateral neck radiograph with soft tissuse technique is of critical value when the diagnosis is in doubt andusually characteristic when compared to the normal. Authors reviewed available lateral neck radiograph of 92 casesamong the 95 cases of clinically confirmed adult epiglottitis during 4 years in wallace Memorial Hospital. Theresults are as follows; 1. Male to female sex ratio was 13:2. 2. The most common age group was 4th decade. 3. Themost common clinical symptoms are sore-throat (87%) and dysphagia(87%). 4. The radiologic findings are swelling ofhypopharynx(92%), vallecular narrowing or obliteration (92%), uvula swelling (33%), narrowing of airway adjacentto epiglottis (17%), swelling of prevertebral soft tissue(8%).

BACKGROUND AND OBJECTIVES: The symptoms of salivary diseasess are often nonspecific, and a variety of investigative methods can be employed. Conventional sialography, which is still widely used for diagnosis of salivary ductal pathologies, has the withdrawback of invasiveness and radiation exposure, and thus ultrasound and magnetic resonance (MR) sialography can replace the conventional tools. This study was performed to evaluate the usefulness of MR sialography for the diagnosis of idiopathic chronic sialadenitis. SUBJECTS AND METHOD: From November 2013 to June 2014, we have retrospectively analyzed 26 patients who have had swelling and pain of salivary glands and undergone MR sialography for further diagnosis of the idiopathic salivary obstructive symptom. We analyzed the symptom scores, salivary flow rate (SFR) and parameters of salivary gland scintigraphy. Then we evaluated correlation among MR sialography findings (duct visualization, grade of stenosis at main duct, degree of sialectasis and glandular volume size). RESULTS: Among the 26 patients, stenosis of salivary duct was observed in 14 patients (53.8%), chronic sialadenitis without stenosis in 6 patients (23.1%), Sjogren's syndrome in 3 patients (11.5%), Juvenile reccutent parotitis in 1 patient (3.8%), and 2 patients were norma (7.7%). The degree of sialectasis was significantly correlated with Tmin (time interval, in minutes, from stimulation to minimum count), maximum secretion (p<0.05), and glandular volume size was also significantly correlated with unstimulated SFR (p<0.05). But others did not show any significant correlations. From these findings, we report three cases that were useful to diagnose the gland disease using MR sialography. CONCLUSION: Resutls show that MR sialogarphy indirectly reflects the salivary gland function. Therefore MR sialography can be helpful when the differential diagnosis of idiopathic chronic sialadenitis is difficult with conventional tools.

A clinical observation was made on 16 cases of urinary tuberculosis under 15 years old from 1975 through 1989. During this period, the incidence of urinary tract tuberculosis in childhood does not seem to decrease and in some cases, the diagnosis was delayed because the tuberculosis is not considered at initial diagnosis. Past history of tuberculosis or present active tuberculous disease other organ system and family history of tuberculosis were noted in half of the cases. We concluded that the children with family history or past history of tuberculosis should be examined for the presence of urinary tract tuberculosis although they are free of symptoms, and that tuberculosis should be considered in children who had recurrent urinary tract infection, but with negative culture for nonspecific organisms.

PURPOSE: To evaluate the clinical features of dry eye in thyroid-associated ophthalmopathy (TAO) according to disease activity and analyze the related factors. METHODS: This study included 157 patients diagnosed with TAO and dry eye between March 2009 and March 2015. According to the clinical activity score (CAS), TAO patients were divided into inactive (CAS < 3) and active (CAS ≥ 3) groups. Clinical features included age, sex, visual acuity, proptosis, palpebral fissure width, orbital computed tomography (CT) findings, thyroid hormones, and ocular surface parameters including tear film break-up time (TFBUT), Schirmer tests, keratoepitheliopathy scores, and ocular surface disease index (OSDI) were obtained and compared between the groups. In addition, correlations between clinical features and ocular surface parameters were analyzed in both groups. RESULTS: In the inactive and active TAO groups, CAS was 1.24 ± 0.69 and 4.23 ± 1.13, respectively (p = 0.001). Thyrotropin-binding inhibitory immunoglobulin was significantly higher in the active TAO group than in the inactive TAO group (p = 0.048). On orbital CT, extraocular muscle hypertrophy was more common in the active TAO group than the inactive TAO group (p = 0.020). No significant difference was found in age, sex, visual acuity, free T4, and thyroid-stimulating hormone between the two groups. During analysis of the tear film and ocular surface parameters, TFBUT (p = 0.006) was shorter and OSDI score (p = 0.028) was higher in the active TAO group than the inactive TAO group. TFBUT was negatively correlated with proptosis (r = -0.432, p = 0.001; r = -0.308, p = 0.032) and palpebral fissure width (r = -0.367 p = 0.012; r = -0.312, p = 0.031) in both groups. OSDI was positively correlated with proptosis in the active TAO group (r = 0.301, p = 0.033). CONCLUSIONS: TFBUT was shorter and OSDI score higher in dry eye patients with active TAO than in patients with inactive TAO. The TFBUT was negatively correlated with proptosis and palpebral fissure width in both groups.
