We present the case of long-term observation of a patient with chronic kidney disease (CKD) caused by advanced focal segmental glomerulosclerosis (FSGS) resulting from underlying congenital chloride diarrhea (CLD). A 20-year-old woman was admitted for prolonged proteinuria despite conservative treatment for CLD. She was diagnosed with CLD and started taking KCl salt supplementation from the time of birth. Mild proteinuria was first found at 12 years of age, which progressed to moderate proteinuria at 16 years of age. At 16 years of age, CKD stage 2 with FSGS was diagnosed based on the initial assessment of the glomerular filtration rate (GFR) and kidney histology. On admission, we re-assessed her renal function, histology and genetic analysis. GFR had deteriorated to CKD stage 4 and renal histology revealed an advanced FSGS combined with tubulointerstitial fibrosis. A homozygous mutation in the SLC26A3 gene (c.2063-1G>T) was found by diagnostic exome sequencing and may have been inherited from both parents. CLD patients can be more vulnerable to renal injury, which may also cause progression of renal failure. Therefore, even if there is an early diagnosis and adequate salt supplementation, close monitoring of renal function and tailored treatment should be emphasized for renal protection and favorable CLD prognosis.

Fatty pancreas is an abnormal process of lipid deposition in cells, resulting in increased fat tissue and obesity. The result is a risk factor for cardiovascular and metabolic diseases. The aim of this study was to evaluate the usefulness of pancreatic fat as a predictor of cardiovascular disease and metabolic syndrome in pancreatic ultrasonography. In 407 patients who underwent a comprehensive screening at the W Health Care Center in Busan from September 2. 2018 to December 31, 2018, the degree of fat deposition in the pancreas was evaluated as the degree of mild, moderate. Data on non-obstructive atherosclerosis, BMI, hyperlipidemia, hypertension, and diabetes were collected to assess the association of pancreatic fat deposition with cardiovascular disease and metabolic syndrome. In addition, we tried to analyze the correlation between liver dysfunction and thyroid dysfunction as the degree of fat pancreas increased. We examined the relationship between six parameters including atherosclerosis, BMI, hyperlipidemia, hypertension, diabetes, liver dysfunction, and thyroid dysfunction among patients with fatty pancreas. We concluded that the carotid intima-media thickness of atherosclerosis, which is a risk factor of cardiovascular disease, is most closely related to fatty pancreas.

Periosteal chondroma is a rare, slow-growing, benign cartilaginous tumor that develops between the periosteum and cortex, but there are no reports of multiple periosteal chondroma of the toes. A 19-year-old male presented with a palpable mass of the right fourth toe with tenderness for one year. A radiology examination revealed multiple, radio-lucent lesions with mild cortical irregularity. The magnetic resonance imaging findings were chondrogenic tumors with multiple, well-defined T1-low and T2-high signal enhanced lesions involved in the fourth proximal, middle, and distal phalanges. The tumors were removed by a surgical resection and curettage. Histologically, the tumors were proven to be periosteal chondroma.

Vaginitis is one of the most common disease in gynecologic field in recent days. About 90% of these patients suffer from the infection of the vagina caused by Gardnerella vaginalis, Candida, or Trichomonas, either alone or in combination. For the effective diagnosis and management, it is essential to get an accurate identification of the causative agent. Applying simple and easy diagnostic methods such as pH of vaginal discharge, amine test and microscopic examination of wet mount preparation of normal saline and 10% KOH to 549 cases of randomly selected patients visiting Out-patient Department of Obstetrics and Gynecology of Yeung-nam University Hospital through May 1st to Sept. 31st, 1987, the following results were obtained. 1. In the Gardnerella vaginitis vaginal pH was more than 5.0 in 81.0% of total cases, positive amine test in 62.8%, decreased lactobacilli in 77.4% & decreased WBC counts in 70.1%, In the Trichomonas vaginitis vaginal pH more than 5.0 was noted in 93.3% of the cases, negative amine test in 90%, decreased lactobacilli in 90% & increased WBC counts in 93.3%, whereas Candida vaginitis and normal groups showed vaginal pH of 3.0~4.0 in 83.2%, negative amine test in 100%, normal distribution of lactobacilli in 89.7%, normal WBC counts in 72.4%. 2. The accuracy rates of physical diagnosis by wet mount preparation of normal saline and 10% KOH revealed 26.3%, 47.5% % 70,0% in Gardnerella vaginitis, Candida vaginitis, and Trichomonas vaginitis, respectively. The vaginal pH and amine test showed 83.2% of accuracy rate in Candida vaginitis group, 60.6% in Gardnerella vaginitis group and 83.3% III Trichomonas vaginitis group. 3. In 23 cases of Gardnerella vaginitis showing vaginal pH of 3.0 or 4.0 and positive amine test, the clue cells were observed in 10% or less in 12 cases, 30% in 5 cases, 50% in 4 cases and 50% or more in 2 cases. In summary vaginal pH and amine test could be useful in screening and differentiating the different types of infectious vaginitis. Furthermore by adding microscopic examination of normal saline and 10% KOH wet mount preparation to them, they not only could obtain higher diagnostic accuracy rate but would be more valuable in selecting the patients requiring cultures to confirm the diagnoses.

The purpose of this observation was to investigate the natural killer cell activities in mice Infected with pathogenic free-living amoeba, Naegleria fowleri and Acanthomoeba culbertsoni according to the infection doses, and infected with non-pathogenic free-living amoeba, Naegleria fowleri. The natural killer cell activity was examined by means of target binding capacity, active NK cell and maximum recycling capacity of the mice after inoculating free-living amoebae with low and high doses. The mice infected with 1 103, 1 105 A. culbertsoni trophozoites showed mortality rates of 6.9% and 65.5%, respectively. The mice infected with 1 104, 1 105 N.fowleri trophozoites showed mortality rates of 5.9% and 72.2%, respectively. The NK cell activities in all experimental groups increased significantly on day 1 after infection as compared with control group, and then remarkably declined thereafter, there was no difference of the cytotoxic activity of the NK cells In mice among inoculation doses of pathogenic free-living amoebae. The target binding capacities of NK cells and percentages of activated NK cells in mice Infected with pathogenic free-living amoebae were slgrlificantly Increased a day after Infection, as compared Uth control group. There was no difference of the maximal recycling capacities of NK cells in all experimental groups as compared Uth control group. There was significant difference in the cytotoxic activity and single cell cytotoxlcity of NK cells between the experimental groups infected with pathogenic free-living amoebae and that infected with non-pathogenic free-living amoebae.

목적 글루포시네이트암모늄은 비선택성 제초제로 1984년 일본에서 개발되었으며, 급성 중독시에는 위장관계 증상뿐만 아니라 의식변화, 경련, 호흡부전 및 기억소실 등과 같은 다양한 임상증상을 보이는 것으로 알려져 있다. 한국에는 1994년 소개된 이후로 널리 사용되고 있으며, 사용량의 증가와함께 음독환자가 점점 증가하여 사회적 문제가 되고 있다. 저자들은 최근 글로포시네이트 중독 환자에서 초기치료 후 지연성 악화를 보였던 2례를 문헌고찰과 함께 보고하고자 한다. 방법 및 결과 첫 번째 증례는 62세의 남자환자로 음주상태에서 글루포시네이트암모늄 음독 후 의식 저하 상태로 발견되어 응급실로 이송되었다. 응급 위세척을 시행 후 보존적 치료 및 집중모니터링을 유지하였고, 의식수준은 6시간 후에 거의 명료한 상태로 호전되었다. 지연성 악화의 가능성에 대해설명하고 지속적인 경과관찰 및 치료를 위해 집중치료실 입원이 필요함에 대해 설명하였으나, 환자와 보호자는 타상급병원으로의 전원을 원하였다. 환자는 이송 중에 발생한 심폐정지로 심폐소생술을 시행하였으나, 회복되지 못하고 사망하였다. 두 번째 증례는 54세의 남자 환자로 글루포시네이트암모늄 음독 후 발생한 의식 변화로 응급실로 이송되었다. 내원시 의식은 혼미한 상태였으며 앞의 증례와 같이 응급 위세척을 시행하였다. 본 환자는 초기치료 후 본원 집중치료실에서 지속적인 혈액 및 생화학적 검사를 시행하였으며, 집중모니터링 및 치료를 유지하였다. 입원 2일째 혈액검사 소견은 호전 중이었으나, 경련이 발생하였으며 의식은 혼미한 상태가 지속되었다. 신경과 협진하여 뇌파검사를 시행 후 항경련제를 증량한 후로 경련은 발생하지 않았다. 입원 7일째에는 의식 수준은 거의 명료한 상태까지 호전되었다. 입원 13일째 혈액 및 생화학검사에서 약간의 혈색소 감소 외에는 정상소견을 보였으며, 뚜렷한 신경학적 합병증 없이 퇴원하였다. 결론 급성 글루포시네이트중독 환자는 매우 다양한 임상증상을 보이며 초기치료 후에 상태가 안정적이더라도 지연성으로 임상적 또는 신경학적 악화가 발생할 가능성이 있으므로 치료에 유의하여야 한다.

생물학 및 의학등의 생명과학에서는 현미경을 이용하여 생체물질 즉, 생체조직을 관찰하고 이에 대한 조직의 검사 결과를 판정하고 발표한다. 이때 필히 고정과정(fixation process)을 거쳐야 한 다. 즉, 생체조직중 조직의 구조, 특정 세포나 바이러스 및 효소등을 관찰할 때 고정과정을 거쳐 조직을 절편하고 이를 염색하여 현미경으로 검사하게 된다. 고정과정이란 생체물질을 안정화시키고 자기분해 혹은 부패를 방지하여 보존이 가능하도록 변화시키 는 과정으로, 조직내의 용해성 물질을 불용성 물질로 변형시키는 과정이다. 고정과정을 거친 생체조직 은 구조를 보존하고 있기 때문에 조직의 훼손이 없는 상태에서 절편이 가능하고 또한 염색상태를 좋게 하며 관찰시 contrast를 증진시킨다. 만약 고정과정을 거치지 않으면 물질의 세포막이 파괴되고 단백질 등의 물질이 용해되어 조직의 변형을 일으켜 제대로 조직을 관찰할 수 없게 된다. 고정과정에는 크게 화학적 고정법과 물리적 고정법이 있다. 화학적 고정법은 생체조직을 화학용액에 처리하는 방법이며, 물리적 고정법은 직접적인 열 혹은 초음파등으로 물질을 고정시키는 방법이다. 표 면과 내부의 열전도가 달라져 고정이 균일하게 되지 않는 단점을 가지고 있기 때문에 보통 2~6일의 고 정시간을 요하는 화학적 고정법을 사용하고 있다. 따라서 조직에 대한 총 검사시간이 최소 6일에서 최 대 12일이 요구된다. 병원등에서 조직검사의 결과가 늦게 발표되는 사유는 바로 화학적 고정법을 사용 하여 생체조직을 관찰하고 그 결과를 판정하기 때문이다. 본 고에서는 마이크로파를 이용하여 약 3시간만에 조직의 상태를 관찰할 수 있는 고정법을 소개한다. 마이크로파를 이용하여 조직을 고정하는 고정방법을 기존의 고정법과 비교하여 이들의 장단점을 나타 낸다. 본 연구자에 의해 개발된 마이크로파 고정기를 소개하고, 이를 이용하여 생체물질을 고정한뒤 절 편, 염색하여 현미경 관찰결과를 발표하여 본 연구의 방법이 기존 방법보다 우수함을 나타낸다.
