Background
: It is especially common in the elderly hypertensive patients that pseudohyperte-nsion is, because of the excessive stiffness of the large arteries, measured higher than the actu-al blood pressure. If misdiagnosed as having pseudohypertension, it may cause the loss of expe-nses and the risk of adverse effects to the patients with unnecessary treatments. Especially, the unnecessary antihypertensive treatment of pseudohypertension in the elderly patients has shown to lead to side effects such as bone fracture by a misstep or a transient ischemic dis-ease. In spite of the clinical importance of pseudohypertension, the studies on this subject and the reports about the frequency(of pseudohypertension) are rare.
Method: From June 20 through June 30 of 1995, blood pressure was measured to the hype-rtensive patients over age 60, who have been treated in a hypertensive center of the department of the Family medicine in a metropolitan hospital. Each patient was measured a standardized in-direct blood pressure by a hand-operated mercury blood pressure gauge and was examined the presence of pseudohypertension with the use of Osler's maneuver. Osler's positive patients were remeasured. The socio-demographic characteristics of the patients and the test center's opinion were computerized and examined with comparison.

Results : Among the 345 subjects of the study, percentages of those over age 60 were 58.2%(201/345), and those under age 60 were 41.7%(144/345). The average age of the subjects was 60.7 for the subjects, there was no Osler positive case under age 60 and 2%(4/201) was found over age 60. The socio-demographic characteristic and the test center's opinion showed signifi-cant correlations with blood pressure, but didn't show any correlations with age, weight, height, a disease, a family history, alcoholic drinking, smoking, habit of eating, and the amounts of cho-lesterol.

Conclusion : The Osler's positive(pseudohypertension) of the subjects found only in those over age 60. According to this fact, at the time of initial blood pressure diagnosis of the elderly hype-rtensive, the unnessary treatment of antihypertension should be prohibited considering the pos-sibility of the presence of pseudohypertension. It is considered that, with the clinical importance of pseudohypertension and prevent from the adverse effects by the antihypertension, a pre-cise measurement of frequency of pseudohypertension by the use of direct blood pressure mea-suring method is necessary. Further study will be required to verify these discoveries in the eld-erly hypertensive patients and to develop noninvasive means of confirming the presence of pse-udohypertension.

Background
: Helicobater pylori are gram-negative spiral bacteria that are associated with gastritis, peptic ulcer, and gastric cancer.

Methods : For detection of Helicobacter pylori infection, we studied 109 patients with upper gastrointestinal disorders from January 1994 to August 1994. The results are as follows.

Results : 1. The reviewed patients was 78 men(71.6%) & 31 Women(28.4%) and average age of them was 51±10.6.
2. H. pylori was isolated from 55(50.5%) cased among 109 patients.
3. According to the endoscopic diagnosis, the detection rates of H.pylori was 56% in gastritis, 53.8% in gastric ulcer, 31.3% in gastric cancer & 25.0% in gastric polyp.
4. According to the anatomical position of stomach, 57.1% in antrum, 44.5% in body, 50.0% in angle, and 33.3% in pylorus.

Conclusion : In conclusion, there was a strong association between the detection of H.pylori and stomach disease, especially gastritis & gastric ulcer.
