Pregnancy related stroke is significant because it has dire impact on both mother and the fetus. Pregnant or puerperal women are reported to have about 13-fold more risk of stroke compared to non-pregnant women. Pregnancy-related stroke must be differentiated from stroke in elderly patients, because it is different in pathophysiological etiologies and recurrence rates and also diagnostic and therapeutic methods may affect the fetal health status. Because the VI cranial nerve manages lateral rectus muscles, it' s palsy causes sudden onset of double vision. The eyes turn medially. In this article, one case of paralytic strabismus resulting from pontine hematoma during puerperium is reported. It was treated with herb medicine and acupuncture. Symptoms improved. This case is submitted with a brief overview of related lit.

Klippel-Trenaunay syndrome (KTS) is a rare congenital malformation syndrome involving blood and lymph vessels, which is characterized by triad of cutaneous hemangioma, venous varicosities, and overgrowth of the affected limbs. Because vascular malformation in KTS can be located anywhere except the face and brain, the clinical presentation could be extremely variable. But there are only rare case reports that KTS is associated with spinal cord lesion. We report a case of recurrent myelopathy in a patient with KTS.

The objective of this study was to determine crop rotation effects on potato yield, soil chemical and microbiological properties from a short-term field experiment from 2010 to 2011 in Jeju Island, Korea. Potato cropping systems included continuous and rotation sequences of soybean (Glycine max(L.) Merr.), barley (Hordeum vulgare var. hexastichon), rapeseed (Brassica napus L.) and broccoli (Brassica oleracea var. italica). Crop rotations increased the yields of potato from 31% to 52% compared with continuous potato. Marketable yield of potato was highest under soybean plus rapeseed rotation by $20.97MT\;ha^{-1}$ and lowest under continuous cropping by $11.95MT\;ha^{-1}$. The incidence and severity of scab disease was significantly lower in tubers from crop rotation with soybean plus barley. Differences in marketable tuber yields among rotations were associated with potato scab disease. Especially, incidence and severity of potato scab were strongly correlated with soil pH, exchangeable calcium, and bacteria population of the soil. Crop rotations significantly increased soil pH, available phosphate, exchangeable K and Ca, especially in crop rotations with soybean plus barley or rapeseed. Soil microbial biomass C of crop rotations with soybean plus barley or rapeseed, was also significantly higher compared with monoculture. In conclusion, crop rotation may decrease the incidence of soil-born pathogen by increasing soil chemical properties and soil microbial biomass. Overall, potato crop productivity was generally maintained in rotations that contained soybean plus barley or rapeseed but declined under continuous cropping system. 본 시험은 윤작처리가 감자의 상품수량과 토양 화학성 및 미생물 활성에 미치는 영향을 평가하고 알맞은 작부체계를 확립하기 위하여 시험을 수행하였다. 작부체계내 콩과 보리를 도입하여 2년 2기작으로 감자를 윤작하였을 경우 총수량과 상품수량은 대조구인 연작구 대비 각각 31% 및 53% 정도 증가하였으며, 콩과 유채를 도입하여 2년 2기작으로 감자를 윤작하였을 경우 총수량과 상품수량은 각각 57% 및 75% 정도 증가하였다. 그리고 감자의 상품수량에 미치는 요인간 상관관계를 분석한 결과 상품수량은 토양미생물 활성, 특히 Biomass C 및 세균 밀도가 높을수록 증가하였고, 토양 pH, 유효인산, 치환성 칼슘함량이 높을수록 세균 밀도가 증가하였다. 따라서 윤작을 통해서 토양 화학성을 개량하고 미생물 밀도 및 활성을 증가시키면, 토양병 발생을 억제하고 감자의 생산성을 높일 수 있을 것으로 판단된다.

목적: 마제신은 신장융합(renal fusion)을 가진 가장 흔한 신기형이다. 저자들은 단일병원에서 관찰된 마제신 환자들의 동반 질환을 포함한 임상적 특징을 조사하고자 하였다. 방법: 2000년 1월부터 2012년 12월까지 부산백병원에서 영상의학적 방법에 의해 마제신으로 진단된 환자 43명을 대상 (소아군 14례, 성인군 29례)으로 후향적으로 의무기록을 분석하였다. 또한 소아군과 성인군의 자료를 비교 분석하였다. 결과: 전체 환자의 진단당시의 평균 연령의 중간값은 34세이었고, 성별은 남자 17명 여자 26명 이었다. 소아군(<18세, 14명)의 평균연령은 $6.7{\pm}6.2$세, 남자가 5명이 있었다. 진단 시 혈뇨를 보인 1명을 제외한 대부분 동반 질환의 평가 도중 우연히 발견되었다. 동반된 질환으로는 터너증후군이 5례(36%)로 가장 많았고, 동반된 비뇨기계 기형으로는 2명(14.2%)에서 신우요관협착을 동반하였다. 신기능은 마지막 추적검사까지 모두 정상이었다. 성인군에서 진단된 29명의 진단 당시 연령 중간값은 48세이었고, 남자가 12명 여자 17명이 있었다. 진단 시 다른 질환의 평가 중 18명이 우연히 발견되었으며, 11명은 혈뇨 또는 결석으로 인한 복통 등이 있었다. 동반질환으로는 터너증후군이 5례로 가장 많았으며, 5명에서 신우요관협착이 동반되었고, 그 외 수신증, 과민성 방광 등을 동반하였다. 마지막 추적검사에서 6명(21%)에서 신기능감소(혈청Cr>1.5)가 관찰되었다. 결론: 마제신은 우연히 발견되는 경우가 대부분으로, 동반된 단일 질환으로는 터너증후군이 가장 많았다. 성인기로 이행 후 다양한 비뇨기과적 합병증의 위험이 높으므로 지속적인 추적 관찰이 필요하다. Purpose: We aimed to investigate the clinical characteristics and associated diseases in children with a horseshoe kidney and compared these data between children and adults. Method: We performed a retrospective analysis of the medical records and radiological findings of 43 patients diagnosed with a horseshoe kidney in the Busan Paik Hospital. The subjects were divided into the children's group (14 cases, age <18 years) and the adult group (29 cases, age ${\geq}18$ years). Results: The study group consisted of 17 males and 26 females with a median age of 34 years. In the children's group (14 cases), 5 subjects were male and 9 were female, with a mean age of $6.7{\pm}6.2$ years. Most of the subjects were asymptomatic and were incidentally diagnosed with horseshoe kidney during their evaluation for another disease. Among the associated diseases in the children's group, Turner syndrome was the most common (5 cases), whereas ureteropelvic junction (UPJ) stricture was observed in 2 cases (14.2%). None of the children exhibited abnormal renal function during the follow-up period. In the adult group (29 cases), 12 subjects were male and 17 were female, with a mean age of 48 years. Eighteen patients were incidentally diagnosed with horseshoe kidney during their evaluation for another disease, and 11 patients had hematuria or abdominal pain due to renal stones. Among the associated diseases in the adult group, Turner syndrome was the most common (5 cases), and UPJ stricture was observed in 5 cases; the other accompanying diseases included hydronephrosis and overactive bladder. Six patients exhibited decreased renal function (serum creatinine level >1.5) during the follow-up period. Conclusion: Horseshoe kidney is usually diagnosed incidentally in both children and adults. In the present study, we noted that Turner syndrome was the most common associated disease in children. In addition, most children were asymptomatic but had a high risk of urologic complications after the transition to adulthood. Therefore, children with horseshoe kidney require continuous follow-up.

This systematic review and meta-analysis aimed to determine whether food intake is effective in preventing diseases related to cognitive impairment. We searched English databases namely MEDLINE, PubMed and ScienceDirect from 2000 to May 2020, and Korean databases namely RISS, KISS, and DBPIA from 1990 to May 2020. We divided the data into 15 groups using the food group classification of the Korean Nutrition Society (KNS). The effect size (Cohen's d) was estimated using a random-effect model, and a 95% confidence interval was calculated for each study. We included 17 cross-sectional studies and 7 cohort studies which involved 45,115 participants. As a result of analyzing the subgroups in the Asian population of both sexes, it was observed that grain intake has a protective effect against cognitive impairment. For females, pulses and fish also have a protective role against cognitive impairment. In the case of seaweed, a negative relationship was found with a moderate protective effect against cognitive impairment (Cohen's d:-0.533, 95% CI: -0.939, -0.126; p=0.010) in Korean studies. Dairy products are associated with an increased risk of cognitive impairment in the American and European population but drinking alcohol is associated with a lower impairment risk. These results provide a basis for formulating the dietary guidelines for preventing dementia for each country.

Polyphenol oxidase-catalyzed oxidation of substrates (t-butylcatechol, 4-methylcatechol, chlorogenic acid, caffeic acid and pyrocatechol) were performed in the Ph range 4~8. Co ncentrations of substrate's major oxidation products were monitored by high performance liquid chromatograph. The nature and amounts of products formed were highly pH dependent. They also were ifluenced by kinds of substrates. Major oxidation product of 4-methylcatechol appeared the maxium value at pH 5, them of chlorogenic acid, caffeic acid and pyrocatechol at pH 6.0 and that of t-butylcatechol at pH 5~7. Time-dependent PPO activity was determined at $4^{\circ}C\;and\;30^{\circ}C$. PPO extracted by phosphate buffer containing triton X-114 (t-PPO) was more stable than PPO by phosphate buffer (b-PPO). The result of electrophoresis, at first PPO was showed only a band at 48 kd. After 1~3 days a partial degrade band was appeared in b-PPO and three partial degrade bands in t-PPO. No activity band was appeared in PPOs at $30^{\circ}C$ and b-PPO at $4^{\circ}C$ after 4 days. And a band (37 kDa) in t-PPO was remained finally and disappered. PPO from Perillae leaves has two activity bands at 48 and 37 kDa in previous paper. It was supposed that PPO in the leaves of Perilla frutescens was a protein having one molecular weight as 48 kDa. And 37 kDa protein, relatively proteolysis-resistant, was a proteolyzed form of a major form.
