The purpose of this study is to construct fundamental information about the ultrasonographic diagnosis for extrinsic and intrinsic abdominal disease. Normal ultrasonography of liver, gall bladder, spleen, kidney, urinary bladder, stomach, pylorus, duodenum, and heart of 4 cynomolgus monkey(Macaca fascicularis) were determined by use of ultrasonography. One cynomolgus monkey was autopsied at the time of euthanasia which is performed 24 hours after ultrasonography, and above mentioned organs were measured actually. In ultrasonography of cynomolgus monkey, the gall bladder was 17.5 cm long, and 6.6 cm wide. The width of spleen was 8.8 mm. The right kidney was 35.5 mm long, 23.7 mm wide, and 15.2 mm deep. The ultrasonographic measurements of the left kidney in calves was similar. The urinary bladder was 27.7 mm long, and 20.5 mm wide.

Polycystic kidney disease (PKD) is a common genetic disorder in which extensive epithelial-lined cysts develop in the kidneys. In previous studies, abnormalities of polycystin protein and its interacting proteins, as well as primary cilia, have been suggested to play critical roles in the development of renal cysts. However, although several therapeutic targets for PKD have been suggested, no early diagnosis or effective treatments are currently available. Current developments are active for treatment of PKD including inhibitors or antagonists of PPAR-${\gamma}$, TNF-${\alpha}$, CDK and VEGF. These drugs are potential therapeutic targets in PKD, and need to be determined about pathological functions in human PKD. It has recently been reported that the alteration of epigenetic regulation, as well as gene mutations, may affect the pathogenesis of PKD. In this review, we will discuss recent approaches to PKD therapy. It provides important information regarding potential targets for PKD.

Objectives: The aim of the present study was to assess the frequency of use, and preferences regarding information and communication technologies (ICTs) among Ecuadorian patients with chronic kidney disease (CKD) undergoing hemodialysis. Methods: We conducted an anonymous cross-sectional survey-based study from January 2016 to April 2017, involving 393 patients with end-stage renal disease from 9 hemodialysis centers, in which they rated their use and preferences of various ICTs through a modified version of the Michigan Questionnaire. The questionnaire collected information regarding demographics, patients' interest in obtaining health-related information through ICTs, and interest in using ICTs as a potential way to communicate with their healthcare providers. A chi-square test for association and adjusted regression analyses were performed. Results: Among all patients who participated, 64.3% reported owning a cellphone, with less than a third reporting active Internet connection. The most used ICT for obtaining information about CKD and/or hemodialysis was web-based Internet, followed by YouTube. SMS was rated the highest to receive and seek health-related information, followed by Facebook. Younger age and higher levels of education were associated with a higher overall usage of ICTs. Finally, more than half of the patients reported interest in using WhatsApp for communicating with their healthcare providers. Conclusions: Understanding the preferences of ICTs among patients with CKD undergoing hemodialysis could help to improve their outcomes through the potential uses and benefits of ICTs. Further research is needed to assess their role in improving the care of patients with chronic diseases.

민들조개에 의해 흡수된 방사성 동위원소의 조직내 분포와 생화학적 거동을 알아 보기 위해 민들조개를 $^{65}Zn,\;^{54}Mn,\;^{137}Cs$ 용액에 7일간 노출시킨 후 조직을 잘라내서 방사능을 측정하고 간과 콩팥을 균질화시켜서 Sephadex G-75 유리판을 통한 젤투석 실험을 하였다. 방사성 동위원소의 조직내 분포는 방사성 동위원소에 따라 서로 다른 조직내 축적경향을 나타냈으며 특히 다른 조직에 비해 간과 콩팥에 아주 높게 농축되었다. 방사능이 농축된 간과 콩팥에서 방사성 동위원소와 결합하고 있는 단백질을 조사하기 위해서 간과 콩팥을 균질화시킨 상등액을 Sephadex G-75 column chromatography로 분리 한 결과 $^{65}Zn,\;^{54}Mn,\;^{137}Cs$가 서로 다른 유출 패턴을 나타냈고 또한 $^{65}Zn$과 $^{54}Mn$은 간과 콩팥에서 서로 다르게 유출되었다. 본 실험의 결과 방사성 동위원소의 종류와 조직에 따라서 결합하고 있는 단백질의 종류가 서로 다른 것을 알 수 있었다.

The purpose of this systematic review and meta-analysis was to assess the preventive effect of theophylline on acute kidney injury and the ameliorative effect of theophylline on renal function in asphyxiated neonates. A literature search of the PubMed/Medline, Embase, and Cochrane Library databases for information published up to February 2019 was conducted. All studies that reported the incidence rate of acute kidney injury, serum creatinine level, and glomerular filtration rate after the randomized administration of theophylline or placebo were included. In total, eight studies involving 498 neonates were eligible. The incidence rate of acute kidney injury was significantly lower in the theophylline group than in the placebo group (risk ratio [RR]: 0.42, 95% confidence interval [CI]: 0.32-0.55, p < 0.001). The changes in serum creatinine level in the theophylline group were significantly higher than those in the placebo group from the first day of life to 3 and 5 days of age (weighted mean difference [WMD]: -0.51, 95% CI: -0.62 to -0.40, p < 0.001, and WMD: -0.26, 95% CI: -0.34 to -0.18, p < 0.001, respectively). The changes in glomerular filtration rate in the theophylline group were significantly higher than those in the placebo group from the first day of life to 3 days of age and the last day of follow-up (WMD: 12.30, 95% CI: 9.39-15.21, p < 0.001, and WMD: 9.35, 95% CI: 6.43-12.27, p < 0.001, respectively). These results suggested that theophylline has a beneficial effect on the prevention of acute kidney injury in neonates with perinatal asphyxia.

A high dietary oxalate intake may lead to calcium oxalate (CaOx) kidney stones in the gastrointestinal tract. Most soy foods contain high concentrations of oxalate and/or phytate. This study analyzed the changes in oxalate (Ox), phytate ($InsP_6$), and calcium (Ca) during soymilk processing from the seeds of Korean recommended soybean cultivars (cvs). The contents of Ox, $InsP_6$, and Ca in 21 cvs ranged from 14, 108, and 148 to 231, 279, and 246 mg/100 g of dry seed, respectively. Seven cultivars were selected from the 21 cvs by the distributions of Ox, $InsP_6$, and Ca. Then, each contents of soymilk prepared from the 7 cvs were determined. All contents were lower in soymilk than in seeds, but the Ox to $InsP_6$ ratios changed from varying ratios (0.1-0.8) to normal ratios (0.8-1.0) in all cvs except 'Paldalkong'. Consequently, during soymilk processing, the Ox content was decreased and the $InsP_6$ content was remained higher than the Ox content although the Ox was likely to be less reductive than the $InsP_6$. These results may provide better information for minimizing the risk of formation of Ox kidney stones due to consumption of soy products.

This study investigated nutritional status and eating behaviors among 59 nephritic patients with mild kidney malfunction in Korea. Nutritional status was measured by blood analysis and 1-3 day dietary recall and records, and eating behaviors were assessed by a questionnaire. Mean Body Mass Index(BMI) was within the normal range, while 21% and 14% of the patients were underweight and overweight, respectively. They received nutrition information mainly from doctors, nurses and mass media, but rarely from nutrition professionals. A quarter of patients skipped breakfast at least 3 times per 12% of the patients, respectively. Energy intake of 83% of the patients was less than the recommended level. Protein intakes of 56% of them were either under or over the recommended levels. Patients had low vitamin B$_2$ and calcium(<75% of the RDA) and excessive phosphorus(138% RDA) and vitamin C(170% RDA). Major food sources to absolute nutrient intakes were similar to those for the average Koreas, except for milk. Milk intake was low in our patients. Dietary quantity and quality were associated positively with BMI, albumin, and HDL-cholesterol and negatively with triglycerides and BUN. Results of this study indicate low nutritional status of the patients and, in turn a need for conducting nutritional education or counselling at regular at regular basis for the nephritic patients with mild kidney malfunction.

본 연구는 proteomics의 방법을 이용하여 가금의 면역시스템에 관련된 단백질을 찾고자 수행하였다. 면역활성 물질을 처리한 후 면역활성화시 발현되는 단백질을 찾아보았다. 이 결과는 가금의 면역과 관련된 단백질 마커의 이용뿐 아니라 현재까지 밝혀지지 않은 가금의 2D map을 만드는데 역시 중요하게 이용이 될 것이다.
