Helicobacter pylori(H. pylori) infection is considered the most important cause of chronic active gastritis and peptic ulcer. To determine the prevalence, distribution and it's relationship to degree of inflammation, gastric biopsy specimens were obtained from 331 nonulcer dyspepsia(NUD) patients consisting of 52 H. pylori negative normal volunteers and 279 H. pylori infected patients. Lymphoid follicles, degree of acute and chronic inflammation(Grade 0 to 3), and degree of H. pylori(Grade 0 to 4) were observed. The prevalence of H. pylori in NUD was 84.29%. The lymphoid follicles were found in 138 patients(41.7%) and only 5 patients(l.5%) without H. pylori showed lymphoid follicles. There was strong a relationship between lymphoid follicles and degree of acute and chronic inflammation and intensity of H. pylori infection(P<0.001). Acute and chronic inflammation were more serious in the antrum than body in H. pylori infected patients. There was no relationship between lymphoid follicles and the site in the stomach of H. pylori infection(P<0.078), but the body portion had an increased frequency of lymphoid follicles compared to the in antrum. Our results indicate that the prevalence of H. pylori infection in Korea is higher than in Western people and the degree of acute and chronic inflammation are strongly correlated with the presence of lymphoid follicles. The lymphoid follicles are believed to be absent from the normal stomach and their presence is strongly associated with H. pylori infection. The fact there is an that increased frequency of lymphoid follicles in H. pylori infected patients, and that they are more prevalent in the body of the antrum, support the concept that H. pylori may be a precursor in the development of primary gastric lymphoma.

The purpose of this study is to compare weight gain by risperidone, clozapine and olanzapine which are atypical antipsychotic drugs with that by haloperidol which is typical antipsychotic drug. METHODS: We performed a retrospective chart review of 278 schizophrenic patients who were treated longer than 12 weeks with 4 different drugs. We measure weight gain weekly until 12th week and weight change curve over 12 weeks was drawn. Additionally, we examined any correlations of weight change with some factors. RESULTS: 1) The highest weight gains were observed in the olanzapine and clozapine groups, followed by the risperidone and haloperidol groups. 2) The haloperidol group showed a main weight gain within first 3 weeks, and patients ingested 3 atypical drugs gained weight steadily during 12 weeks. 3) The initial underweight group showed the largest weight gain. CONCLUSION: This study shows that the atypical antipsychotic drugs induced more weight gain than haloperidol. And we can expect that long-term treatment with clozapine and olanzapine would induce more severe weight gain, particularly in underweight patients.

Since the behavior of malignant cells can be predicted by their histologic appearance, various attempts have been made to develop a uniform grading system for prostatic cancer. The system employed at the University of Texas M.D. Anderson Hospital(MDAH system) is based simply on assessment of percentage of gland formation in the tumor. Herein, using the modified MDAH system, histologic grading and prognosis were retrospectively reviewed in 35 patients with prostatic adenocarcinoma managed at Chonnam University Hospital between l997 and 1984. The following results were obtained. 1. The average age of all the patients was 70.1 years, with a range of 25 to 85 years. 2. In 35 patients, the modified MDAH system identified 6 patients (l7%) as Grade 1, 15(43%) as Grade 2-3, and 14 (40%) as Grade 4. There were a 83% 3-year survival for Grade 1 patients, a 69% 3-year survival for Grade 2-3 patients, and a 17% 3-year survival for Grade 4 patients. 3. Of 15 patients with clinical stage D, 2 had Grade 1, 6 had Grade 2-3, and 7 had Grade 4.There were a 100 % 3-year survival for Grade 1 patients, a 50% 3-year survival for Grade 2-3patients, and a 14% 3-year survival for Grade 4 patients.

BACKGROUND: The effects of a newly synthesized potassium channel opener, KR-30816((-)(nitro-2-hydroxymethyl-2-methy-2H-1-benzopyran-4-y1)pyridine oxide) on the action potential of papillary muscles of guinea pigs and the ATP-sensitive potassium channel current(IKATP) of single ventricular muscle cells of rats were examined to make clear its action mechanism of the KATPchannel. METHODS: We used the conventional microelectrode and the excised inside-out patch configuration. RESULTS: KR-30816 caused a shortening of the action potential duration in dose-dependent manner, which was inhibited by glibenclamide(3microM). Before run-down of the K+channel, KR-30816 activated the cardiac ATP-sensitive K+ channel only in the presence of ATP and shifted the dose-response relation curve between [ATP]i and the channel activity to the right in parallel. After run-down of the KATP channel, KR-30816 did not after the channel opening either in the absence or in the presence of UDP. CONCLUSION: These results suggest that KR-30816 antagonizes the inhibitory effect of ATP on the KATPchannel in a competitive manner, thereby enhancing the channel openings.

Spontaneous fistula formation between the kidney and the colon is uncommon. The underlying cause is usually a pyonephrotic kidney which becomes adherent to a portion of the colon and then ruptures spontaneously, thus creating a fistula. Herein we present a case of renocolonic fistula which occurred in a 36-year old man with review of the literature.

To evaluate the role of p53 and NDP-K/nm23(nm23) protein as a prognostic factor and their relation to metastasis of cancer, we studied metastatic and nonmetastatic gastric carcinoma specimens by immunohistochemical staining. Among the 101 specimens examined, 37(36.6%) showed positivity in staining for p53 protein and 64(63.4%) showed no detectable p53 protein in tumor cells. p53 overexpression was correlated with depth of invasion, lymphatic invasion, lymph node metastasis and distant metastasis. Out of 101 specimens, 35 cases had no staining for nm23. 62 cases(61.4%) exhibited a cytoplasmic staining on most cells and 42 cases (41.6%) had nuclear staining. In 16 of 101 cases(15.8%), a mild to moderate membranous staining was observed in some cells. Cytoplasmic nm23 expression was negatively correlated with lymph node metastasis(P < 0.01) and distant metastasis(P < 0.01). The nuclear nm23 expression showed negative correlation with depth of invasion(P < 0.01), lymphatic invasion(P < 0.01), lymph node metastasis(P < 0.01), and distant metastasis(P < 0.04). The membranous nm23 expression revealed negative correlation with lymphatic invasion(P < 0.02), lymph node metastasis(P < 0.01) and distant metastasis(P < 0.02).

BACKGROUND: The purpose of this study was to assess the effects of succinylcholine(Sch) for insertion of laryngeal mask airway(LMA) during general anesthesia. We compare the bronchoscopic grade, incidence and severity of postoperative sore throat. METHODS: Seventy patients were randomly divided into two groups. The succinylcholine(Sch) group received Sch 1.0 mg/kg, saline group received the same volume of saline 1 minute before the insertion of LMA. Anesthesia was induced with fentanyl 2 g/kg and propofol 2.5 mg/kg. Once the LMA was in the hypopharynx and the cuff inflated, a fiberoptic bronchoscope was immediately passed down through the LMA, and its position was graded from the mask aperture bars. No. of attempts, postoperative sore throat and other complications were also noted. RESULTS: The bronchoscopic grade were aggravated in the Sch group(grade I, n=12; grade II, n=13; grade III, n=10), compared with saline group(22;9;4). The incidence and severity of postoperative sore throat in the recovery room were reduced in the Sch group. No. of attempts were not significantly different. CONCLUSION: The use of Sch for insertion of LMA during general anesthesia aggravated the bronchoscopic grade. However, the incidence and severity of postoperative sore throat could be reduced in the Sch group.

Despite various methods of treating acute lower limb ischemia, the reported mortality continues to be in the 10% to 30% range. To evaluate the results according to etiology, location, time interval before starting treatment of acute lower extremities occlusive lesion, this study was done for 38 patients with acute arterial occlusive disease. The causes of acute lower limb occlusion were embolism (n=18, 47.4%) and thrombosis (n=20, 52.6%). The mortality rate was 11.1% (2/18) in embolism and 10% (2/20) in thrombosis. All the patients with embolic occlusion were treated by thromboembolectomy with Fogarty catheter, and thrombotic occlusive lesion were treated by intraarterial thrombolytic therapy only (n=3), followed by corrective procedure such as PTA only for short iliac arterial lesion (n=1), PTA and stent for long iliac arterial lesion (n=5), bypass operation (n=5). The amputation rate was higher (p,<0.05) in thrombotic group (6/20, 30%) than in embolic group (2/18, 11.1%), in longer duration group (>24 hr, 7/20, 35.0%) than in shorter duration (<24 hr, 1/18, 5.6%), and in multiple lesion (7/13, 53.7%) than single lesion (1/25, 10.0%). Even though advanced therapeutic modality for acute lower limb occlusive disease, mortality is still high, and limb salvage is dependent on various factors such as status of patients, etiology and number of lesion site, time interval before starting treatment.

Ventricular premature complexes (VPCs) are known to be one of the most benign cardiac arrhythmias when they occur in structurally normal hearts. We experienced a 32-year old man who presented with dyspnea, palpitations and very frequent VPCs (31% of the total heart beats). Echocardiography revealed a dilated left ventricle (LV 66 mm at end-diastole and 57 mm at end-systole) and a decreased ejection fraction (34%). Very frequent VPCs had been detected 10 years previously and he underwent a failed radiofrequency catheter ablation (RFCA) procedure at that time. The patient had been treated with heart failure medications including betablockers, ACE inhibitors and spironolactone for the two most recent years. Six months after we eliminated these VPCs with a second RFCA procedure, the heart returned to normal function and size. Long standing and very frequent VPCs could be the cause of left ventricular dysfunction in a subset of patients who suffer with dilated cardiomyopathy, and RFCA should be the choice of therapy for these patients.

OBJECTIVE: To evaluate the effect of preemptive swallowing stimulation on the recovery of swallowing function in long-term intubated patients. METHOD: Patients in the intensive care unit intubated for at least 48 hours due to respiratory distress from March to August 2003 were randomly assigned to two groups. Fifteen patients were stimulated (experimental group), and 18 patients were not stimulated (control group). The duration of intubation was 15.5+/-6.7 days in the experimental group and 15.7+/-6.5 days in the control group. Duration of stimulation in the experimental group was 7.3+/-3.6 days. After extubation, we compared the severity of dysphagia via video-fluoroscopic swallowing study. RESULTS: There was no difference in percentage of aspiration and swallowed volume between two groups. Oral transit time of the experimental group (0.37+/-0.07 sec) was significantly shorter than that of the control group (0.83+/-0.10 sec), and the oropharyngeal swallowing efficiency of the experimental group (73.3+/-17.4%/sec) was significantly higher than that of the control group (50.1+/-13.0%/sec). CONCLUSION: Preemptive swallowing stimulation in long term intubated patients may facilitate recovery of dysphagia.
