Background and Objectives: With increasing age of population, stroke and dementia become greater health problems in Korea. However, there have been no studies on poststroke dementia in Korea. We intended to elucidate the frequency and clinical correlates of poststroke dementia in a hospital-based cohort. Methods: From July 2001 to July 2002, 372 patients were hospitalized to Eulji General Hospital within 7 days from onset with acute stroke or transient ischemic attack. Two hundred-eight patients (55.9%) were followed up and interviewed more than 1 year later (451 ±83.3 days). Dementia was diagnosed by Korean Dementia Screening Questionnaire (KDSQ) obtained by a direct interview. Based on Eulji Stroke Registry, demographic factors, risk factors for stroke, stroke characteristics, and stroke outcomes were gathered and examined. Results: Of 208 patients, poststroke dementia was detected in 36 patients (17.3%, 20 males, age=64.5±9.4 years). Poststroke dementia was associated with history of stroke, aphasia, modified Rankin Disability Scale (MRDS) at 3 month after stroke and when interviewed, and Barthel index at 6 months after stroke (p;0.05). Its correlation with diabetes mellitus and National Institute of Health Stroke Scale at discharge were marginally significant (0.05;p;0.1). Conclusions: Post-stroke dementia is common in Korean stroke patients. Its frequency is comparable to that in other countries. The correlates of poststroke dementia and their clinical meanings are demonstrated.
혈관성 파킨슨증의 경사에코 자기공명촬영 소견 : 환자-대조군 연구 A Case-Control Study

Background & objective : Changes of signal intensity in the various Structures of basal ganglia(BG), Which can be detected by gradient echo MRI(GE-MRI). have been reported in different kinds of parkinsonism Altered iron content in these structures may be a possible explanation of above phenomenon Vascular parkinsonism is a kind of parkinsonism syndrome and is common However. There have been no reports about the BG signal changes on GE-MRI in vascular parkinsonism Methods : We investigated the difference of signal intensity in various BG and midbrain structures between 36 patients with vascular parkinsonism. which was defined as clinical parkinsonism+evidence of relevant vascular lesion on MRI+poor or no response to levodopa, and age-& sex- matched controls. The intensity of BG on GE-MRI was graded as 0-3 relative to cortical gray matter Results : There were no significant differences in clinical characteristics between two groups Among patients with vascular parkinsonism, hypointensity was observed in globus pallidus in 94.4%. in putamen in 58.3% in head of caudate in 33.3%, in substantia nigra in 72.2%,& in red nucleus in 52.8% There was no significant linear trend in the association between signal intensity of above structures and the presence of vascular parkinsonism (p>0 05 on Mantel-Haenszel chi-square test) However, the correlation between the degree of white matter lesions and the presence of vascular parkinsonism was statistically significant (p=003). Conclusions : Our GE-MRI study fails to prove that iron content of various BG structures in patients with vascular parkinsonism is different from controls.

Maize hybrids were planted on April 1, April 25, May 20 and June 15 in 2012, 2013 at the experimental paddy and upland fields in Suwon city , respectively to know changes of growth stage and yield according to different planting time. Maize planting on April 1 was not recommended because total growing days at planting on April 1 was not different with that at planting on April 25 due to many days from planting to emergence over 20 days at planting on April 1. Total growing days were not much different among three planting time after April 25 because days from silking to maturity was lengthened though days from planting to silking was shortened at later planting time. Stalk weight was decreased as planting time was delayed, particularly at planting times after May 20 at paddy field by excess water injury during early growth stage. But, grain yield was not low as in May and June. It is needed to introduce early maturity maize variety as Yanganok at late planting for higher grain yield and enough time for soil preparation for next winter crops
Characteristics of Synchronous Cancers in Gastric Cancer Patients

Purpose: The primary objective of the current study was to investigate the characteristics of synchronous cancers in gastric cancer patients. Materials and Methods: We analyzed the 2,237 patients who were diagnosed between December 2000 and December 2003 with gastric cancer and synchronous cancers of organs other than the stomach.Results: 73 (3.3%) of a total of 2,237 gastric cancer patients had synchronous primary cancers. Among these 73 patients, 71 had one synchronous cancer, and two patients had double synchronous cancers. Colorectal cancer (26 patients, 34.7%) was the most frequently encountered synchronous cancer, followed by cancer of the lung (16 patients, 21.3%), esophagus (13 patients, 17.2%), and liver (8 patients, 10.7%). Synchronous cancers were detected with increased frequency in the elderly, in the patients with multiple gastric cancers, in the patients with differentiated gastric cancer, and in the patients with early gastric cancer, as determined on univariate analysis, but the differentiation of gastric cancers was the only risk factor for synchronous cancers on the multivariate analysis. Conclusions: The differentiation of gastric cancer cells may be a risk factor for synchronous cancers in gastric cancer patients. Careful surveillance by the physician for synchronous cancer is warranted for the patients suffering from gastric cancer. (Cancer Res Treat. 2006;38:25-29)
