  • Poststreptococcal glomerulonephritis (PSGN) is one of the most recognized diseases in pediatric nephrology. Typical clinical features include rapid onset of gross hematuria, edema, and hypertension, and cases are typically preceded by an episode of group A ${\beta}$-hemolytic streptococcus pharyngitis or pyoderma. The most common presenting symptoms of PSGN are the classic triad of glomerulonephritis: gross hematuria, edema, and hypertension. However, patients with PSGN sometimes present with unusual or atypical clinical symptoms that often lead to delayed diagnosis or misdiagnosis of the disease and increased morbidity. Additionally, the epidemiology of postinfectious glomerulonephritis (PIGN), including PSGN, has changed over the past few decades. This paper reviews atypical clinical manifestations of PSGN and discusses the changing demographics of PIGN with a focus on PSGN.

  • Routine urinalysis is a simple, economical, and useful test that facilitates the detection of urinary system diseases and monitoring of renal disease progression. It consists of 4 parts of specimen evaluation, gross examination, a dipstick urinalysis, and a sediment microscopic urinalysis. Urine specimens should first be evaluated in terms of acceptability, and thereafter, the gross appearance is examined for color, turbidity, and odor. In particular, a dipstick urinalysis is an easy and rapid test that provides information on the multiple physicochemical properties of the urine sample. Moreover, although a sediment microscopic urinalysis is time-consuming, it provides information on the cells, microorganisms, casts, and crystals. In the present report, the clinical significance of the routine urinalysis and the problems concerning interpretation are summarized.

  • We have cloned a novel mouse zinc finger protein gene Znf313 by rapid amplification of cDNA ends (RACE) according to the homologue of human ZNF313 gene. The cDNA is 2,163 base pairs (bp) in length and encodes a 229 amino acids (aa) protein with a $C_3HC_4$ ring finger domain and three $C_2H_2$ domains. 89% and 93% nucleotide (nt) and aa sequence identity is observed with its human homologue. Revealed by Northern blot and RT-PCR, full mRNA consists of 2.16 kb and widely expresses in tissues as a single transcript, most abundantly in heart, liver, kidney and testis. The expression of Znf313 in testis is detected in all development stages. Western blot analysis also reveals that Znf313 is expressed in the tissues. Immunohistochemical staining and subcellular localization demonstrate that Znf313 is expressed both in the cytoplasm and nucleus whereas predominantly localized in the nucleus. Present data suggests that Znf313 gene might play a fundamental role in gene transcription and regulation in organism and relates to spermatogenesis.

  • Objectives : An accurate judgment of prognosis when treating diseases is crucial. While the 『Shanghanlun(傷寒論)』 deals with the prognosis of the Three Yin Diseases with great importance, full-scale studies have been lacking. This paper aims to study the Three Yin Diseases with a focus on prognosis analysis. Methods : Among the Three Yin Disease verses, those that could provide clues to prognosis were selected and analysed. Conclusions & Results : When Yang pulse patterns such as long(長脈)·floating(浮脈)·rapid(數脈) pulses and Yang symptoms such as fever, vexing heat, mild perspiration, thirst, warmth in hands and feet are present in Yin disease, it could be taken as signs of Yang Qi restoration. In these situations, Yin Cold pattern such as diarrhea and reversal cold disappear and the prognosis is positive. However, despite Yang pulse patterns and symptoms, there are cases where diarrhea happens as a result of cold dampness being eliminated due to Yang Qi restoration. Also, when Yang Qi starts communicating smoothly after its restoration in the Three Yin Diseases, perspiration can happen. When diarrhea and reversal cold, which are patterns of Yin Cold get worse, with pulse patterns such as unfelt(脈不至)·replete(實脈)·fulminating(脈暴出) pulses, false heat symptoms such as fever and hot flashes happen, accompanied with Yang Qi depleted symptoms such as inability to lie down due to agitation, continuous perspiration, sore throat, dyspnea, and exaggerated breathing happen. When fast pulse, fever, and perspiration are present due to depression and stagnation of ministerial fire, symptoms such as bloody stool with pus, purulent abscess, sore throat, and inability to lie down due to agitation show, which signal negative prognosis. In bad cases of Reverting Yin Disease, there is continuous diarrhea and bloody stool with pus, which can be due to either Kidney Yang deficiency or depression and stagnation of ministerial fire. It could also be caused by excessive heat.

  • 목적 : Endothelin-1은 cyclosporine A와 관련된 신독성의 발생에 관련될 것으로 생각되고 있다. 이에 저자 등은 cyclosporine A가 혈액 및 요중 endothelin-1치에 미치는 영향을 알아보고자 하였다. 방법 : 1996년 2월부터 1997년 3월까지 스테로이드 의존성 미세변화형 신증으로 진단받고 cyclosporine A를 투여받은 15세 미만의 환아 9례를 대상으로 cyclosporine A 투여 전과 투여 3개월 후의 혈장과 소변에서 endothelin-1치를 측정하였다. 평균 연령은 $8.3{\pm}4.6$세였다. 결과 : (1) 혈중 endothelin-1치는 cyclosporine A 투여 전에 $3.22{\pm}0.39$ pg/mL였고, cyclosporine A 투여 3개월 후에 $3.84{\pm}1.52$ pg/mL로 유의한 차이가 없었다(P=0.64). (2) 요중 endothelin-1치는 cyclosporine A 투여 전에 $21.8{\pm}5.8$ pg/mL였고 cyclosporine A 투여 3개월 후에 $20.3{\pm}3.1$ pg/mL로 유의한 차이가 없었다(P=0.30). 결론 : 혈액 및 요중 endothelin-1치는 비교적 단기간의 cyclosporine A 투여에 의해서는 유의한 변화를 보이지 않았으며, 향후 장기간의 cyclosporine A 투여가 endothelin-1치에 미치는 영향에 대한 연구도 필요할 것으로 생각된다.

  • Purpose: Congenital anomalies of the kidneys and urinary tract (CAKUT) are the most common anomalies identified in newborns. This study aims to demonstrate the prevalence of CAKUT including hydronephrosis diagnosed by antenatal and postnatal ultrasound over a five-year period. Methods: The records of births between May $1^{st}$, 2009 and April $30^{th}$, 2014 at our hospital were collected. The number of infants who underwent renal ultrasound after birth for the detection of CAKUT was counted. The incidence of each type of CAKUT such as hydronephrosis, size abnormality, horseshoe kidney, and Multicystic dysplastic kidney (MCDK) was retrospectively evaluated for antenatal screening and postnatal follow-up examination. Results: During the study period, 33,276 infants were born and 521 neonates underwent postnatal renal ultrasound. 183 cases of CAKUT were detected prenatally and 140 postnatally using ultrasonographic examinations at the following time: (i) 3-7 days postnatally in 123 newborns (87.9%), (ii) during 1-3 months in 11 newborns (7.9%), and (iii) later than 3 months in 6 newborns (4.3%). Among diagnosed CAKUT, hydronephrosis was the most common anomaly with 113 newborns diagnosed prenatally and 46 postnatally. Duplex kidney was the second most common anomaly followed by horseshoe kidney, simple cysts in the kidney and so on. Conclusion: The detection of CAKUT is an important part of the prenatal ultrasound. This study analyzed the prevalence of CAKUT detected on prenatal screening and compared the results to those detected postnatally. Prenatal ultrasound screening fulfills the needs of postnatal examinations and therefore, both antenatal and postnatal sonographic investigations are of vital importance for diagnosis of renal and urinary tract anomalies.

  • Herbal medicines are increasingly used to treat various diseases and lots of studies have been reported that they had benefits in treating and preventing of diseases. But organic toxicity is increasingly recognized as herbal medicines become more popular in industrialized countries. Some herbal products potentially benefit people with lots of diseases, however these benefits remain generally unproved in humans, and a greater awareness for potential adverse effects is required. A herb containing a wide variety of, mostly unknown, substances may well include some with unwanted effects. This review focuses on emerging organic toxicities that have been observed associated with various herbal preparations involving the liver, kidney, and heart, and patterns of organ injury, potential risk factors for organic toxicities. In addition to the potential for organic toxicities, drug drug interactions between herbal medicines and conventional agents may affect the efficacy and safety of concurrent medical therapy. Appropriate reporting and regulatory system to monitor herbal toxicity are required, in conjunction with ongoing scientific evaluation of the potential benefits of phytotherapy.

  • Flounder culture has been developed mainly in the western parts of japan, and, to date, following six bacterial diseases have been reported. Bacterial white enteritis occurs in 16 to 30-day-old flounder larvae and often causes mass mortality in seed production. Bacterium named Vibrio sp. INFL invades and multiplies in the mucosae of posterier part of intestine, and causes desquamative enteritis. Gliding bacterial disease occurs mostly in juvenile stage and in spring to summer. Diseased signs are partial discoloration and erosion of skin and fins. Histologically, epidermis are removed, and the causative bacterium, Flexibacter maritimus, multiplies on the surface of demis and invades into the muscular tissue. Vibriosis caused by Vibrio anguillarum and related organisum is one of the well-known diseases among marine fish. Outbreaks of the disease in flounder culture are relatively few, but mass mortalities in fingerlings due to the disease were reported. An outbreak of nocardiosis in the autumn of 1984 has been reported, but since then the disease scarcely occurred. The disease is characterized by formation of abscesses under the skin and white nodes in the gill, heart, spleen and kidney. Streptococcicosis occurs frequently in recent years. Beta-hemolytic streptococcus is the causative bacterium, which possesses the same biochemical and serological characteristics as $\beta$-streptococci isolated from some marine and freshwater fish, and is seemed to related to Streptococcus iniae. Edwardsiellosis is the disease that causes most damage in flounder culture in Japan. Characteristic symptoms are swelling of abdomen and intestinal protrusion from the anus due to accumulation of ascites. Edwardsiella tarda, a well-known pathogen of freshwater fish, is the causative bacterium of the disease.
