Purpose: This study was conducted to explore the health effects of exposure to oil-contaminated water in G village near the area of Daecheon beach on which air force had test fired. Methods: Eighty residents consented and were divided into three groups; 33 residents(drinking well water and still living there), 23 residents(drinking well water but do not live there any more), and 24 residents(did not drink well water but live there now: control group). Data were collected from August to September, 2010 from the survey questionnaires, general health examination, specific functional test, and biological marker tests. Results: Current residents showed higher levels of body mass index, blood pressure, and fasting blood glucose that are related to adult diseases. 64 participants received specific test for cancer. Only one person had esophageal cancer. Perchloroethylene was not found in the Urine Samples. Current residents showed a higher level of 8-hydroxydeoxyguanosine, an indicator of oxidative damage, and there was a statistically significant difference after correcting the confounding variables. Conclusion: We need education programs for managing the risk factors that are related to adult diseases in people who are now living in this village. We also need to expand further studies for investigating oxidative damage indicators.

Purpose: Paraquat, a globally used herbicide, is highly toxic to human beings. Hence, we reviewed some cases of paraquat poisoning in Korea. Methods: We analyzed the clinical and laboratory findings of 50 patients poisoned with paraquat retrospectively. The patients were admitted to the department of internal medicine in the Eumseong KeumWang hospital from January 2008 to December 2008. Results: Among 50 cases of paraquat poisoning, 28 cases were male. Twenty-four cases (48%) were over 60 years old. Fourty-nine patients ingested paraquat on purpose as suicidal attempts, while 1 patient underwent accidental ingestion. Seven patients swallowed less than one mouthful of paraquat, of which 4 patients survived. Eleven patients swallowed two mouthfuls of paraquat, of which 8 patients survived. Thirty-two patients swallowed over three mouthfuls of paraquat and they all died. Thirty-one patients with leukocytosis died. Twenty-one patients with metabolic acidosis died. Increased levels of blood amylase and glucose were related to high mortality, and increased level of blood creatinine was related to severe mortality. Hemoperfusions were accomplished in 27 patients of paraquat poisoning, of which 12 patients survived. Conclusion: Paraquat is a highly toxic herbicide. When patients arrive at the hospital, laboratory findings, urine paraquat concentrations, arrival time, and the amount of paraquat consumed must be considered for treatment plan.

Streptococcus agalactiae or group B streptococcus (GBS) is associated with infections in neonates and pregnant women. Herein, we describe a rare case of GBS renal abscess with peritonitis and pleural effusion in a 17-year-old girl with type 1 diabetes mellitus. The girl was admitted due to fever and right flank pain. Laboratory findings included leukocytosis and increased C-reactive protein level and erythrocyte sedimentation rate. Her serum glucose level was 484 mg/dL. Urinalysis showed no pyuria. Renal sonography revealed parenchymal swelling in the right kidney. The patient was administered intravenous cefotaxime. Urine and blood cultures were negative. Fever seemed to improve, but the following day, she complained of abdominal pain and fever. Antibiotic was switched to imipenem, and abdominal and pelvic CT revealed a ruptured right renal abscess, peritonitis, and bilateral pleural effusion with atelectasis. Pigtail catheter drainage of the abscess was performed. Culture from the abscess was positive for GBS, and fever subsided 2 days after the drainage. She was discharged with oral cefixime. The clinical course of urinary tract infections (UTIs) can be atypical in patients with diabetes, and GBS can be a cause of UTIs. Prompt diagnosis and management are necessary to prevent complications in patients showing atypical courses.

We compared the hypoglycemic effects of Ginseng Radix Alba (GRA) and Mori Folium (MF) in multiple low dose (MLD) streptozotocin(STZ)-induced diabetic rats. In order to induce hyperglycemic state 25 mg/kg of STZ was injected intraperitoneally for 5 consecutive days. SD rats were randomly divided into diabetic control and treatment groups. Treatment groups were administered with either 500 mg/kg of GRA (G500), 500 mg/kg of MF (M500), or 250 mg/kg of GRA mixed with same dose of MF (GM250) for 3 weeks. Blood glucose level and body weight were measured every 5th day. G500 and M500 both significantly reduced blood glucose levels as compared to the diabetic control group (diabetic control, 458.3$\pm$25.4 mg/dl; G500, 275.0$\pm$12.0; M500, 278.0$\pm$15.4; GM250, 324.0$\pm$18.4). While body weight in diabetic control group was decreased slightly after 3 weeks, treatment groups showed gradual increases of body weight during 3 week-period. Plasma insulin level was increased by treatment with GRA, but those levels in M500 and GM250 groups were similar to the diabetic control (normal control, 32.0$\pm$13.9 $\mu$IU/mι; diabetic control, 12.4$\pm$1.9; G500, 17.5$\pm$3.4; M500, 11.1$\pm$3.2; GM250, 10.5$\pm$t3.7). Urine glucose levels were also remarkably reduced in all treatment groups (normal control, 0.0$\pm$0.0 g/day; diabetic control, 11.4$\pm$2.5; G500, 4.9$\pm$0.2; M500, 5.7$\pm$1.6 ; GM250, 8.2$\pm$0.2). At the second and third week of the treatment, food and water intakes were determined. At the third week, food and water intakes were significantly decreased in all treatment groups. Taken together, we may conclude that GRA and MF alone may prevent or delay the development of hyperglycemia, however, synergistic hypoglycemic activity was not be seen in group treated with mixed formula of GRA and MF when compared to GRA or MF alone.

곡식의 혼합비율은 백미에 보리쌀과 밀쌀을 각각 15%, 30%, 45%의 비례로 혼합하였고 비교군으로써 순백미군과 20% sugar casein diet를 두어서 총 8 group 으로 나누었다. 흰쥐 생후 $45{\pm}5$ 일(日) 된 albino rat로써 initial body weight 가 male이 $58{\pm}2\;g$, female이 $62{\pm}2\;g$ 이 되는 80 마리의 쥐를 8 군으로 하여서 한 군에(female 5, male 5)씩 나누어서 총 14주일 사육하였다. 성장율, 식이섭취량, F.E.R. P.E.R. 를 비교하여 보면 순백미 또는 백미에 보리를 혼합한 군보다 백미에 밀쌀을 섞은 군이 더 좋은 성장율과 F.E.R. 및 P.E.R. 을 나타내 주었다. 이와 같은 경향은 male군인 경우 female군보다 더 현저하나 nitrogen retention 에 역시 밀쌀 혼합군이 백미군이나 백미에 보리쌀을 혼합한 군보다 현저히 우수함을 볼 수 있으며 몸무게 증가와 밀접한 관계를 지니고 있음을 볼 수 있다. 곡류 diet 에서 배설된 nitrogen 중 $10{\sim}20%$가 변으로 배설되는 반면 표준군인 경우 nitrogen 이 거의 urine 으로 배설됨을 볼 수 있다. 이와 같은 결과는 곡류식인 경우는 함유된 단백질이 동물성 단백질식이에 비해 소화흡수되는 율이 저조하다. 혈청내 glucose 는 몸무게 증가와 밀접한 관계가 있었다. cholesterol 은 표준군이 곡류 diet 보다 total cholesterol 함량이 감소했으나 esterified cholesterol 과 free cholesterol 의 비에서 보면 곡류식이군이 표준군보다 높았다. 본 연구에서는 nitrogen 의 배설 상태 및 몸무게증가현상으로 미루어 밀쌀 혼합군이 보리쌀 혼합군보다는 우수하다는 결론을 지을 수 있다.

Objectives : This study aimed to evaluate the effect of Atractylodis Rhizoma Alba water extract on streptozotocin (STZ)-induced diabetes in rats. Methods : Male Sprague-Dawley rats were divided into four groups ; normal, STZ-control and Atractylodis Rhizoma Alba (A) water extract-administrated group. Rats in which diabetic was induced by intraperitonal injection with STZ(60 mg/kg body weight). STZ-induced diabetic rats were orally administrated A extract daily for 5 weeks at doses of 200 or 500 mg/kg. Fasting blood glucose, total cholesterol, triglyceride and blood urea nitrogen were measured in sera of rats. Total volume of urine and urinary creatinine were also measured. Histopathological examination and immunohistochemical staining for the expression of insulin and ${\alpha}$-SMA in pancreas and kidney were performed, respectively. Results : There were no differences in body and kidney weights between STZ-control and A extract-administrated groups. However, serum triglyceride level was significantly decreased in A extract-administrated groups compared with those of STZ-control group. Histopathological analysis of pancreas and kidney revealed increased the number of islets and insulin-positive beta-cells in pancreas, and decreased morphological changes of glomerulus and ${\alpha}$-SMA expression in kidney after the administration of A extract. Conclusions : These results suggest that Atractylodis Rhizoma Alba has a biological action on STZ-induced diabetes in rats via decreasing the serum levels of total triglyceride, and suppressing the morphological changes of pancreas and kidney.

Objectives : The aim of present study was to investigate recovery effects of gypsum, which has been used clinically in diabetes therapy. Methods : We established three groups, normal, control, and gypsum, and assigned 6 rats to each group. The normal group was not treated by any process and fed normal saline. The control & gypsum groups were administered streptozotocin(STZ) to induce diabetes. Gypsum extract was orally administered to the gypsum group for 10 days. After 8 weeks, the rats were sacrificed and their body weight, 24hrs urinary protein excretion, glucose, albumin, BUN, creatinine, total-cholesterol, LDL-cholesterol, triglyceride in blood, level of glycation end-product (AGE) and transforming growth factor ($TGF-{\beta}1$) in serum were measured. Morphological profiles and morphometric studies of the kidney cortex. renal transforming growth factor ($TGF-{\beta}1$) expression, macrophage/monocyte antigen (ED-1), and type IV collagen expression were studied. Results : The following results were obtained. The protein amount in urine per 24hrs of the gypsum-treated group as compared to the control was significantly reduced. The BUN and creatinine level in serum of the gypsum-treated group as compared to the control was significantly inhibited. The construction change in the kidneys of the gypsum-treated group as compared to the control was significantly inhibited. The factor of the gypsum-treated group as compared to the control was significantly inhibited. which induced the structural change in the kidneys. Conclusions : The above results suggest that gypsum partially improved kidney function.

산모의 당뇨병은 조산과 함께 광범한 선천성 기형을 야기한다고 알려져 있다. 고혈당이 원인으로 제시되었지만 알려진 것은 별로 없다. 당뇨병의 모델로서 췌장을 부분절제한 동물의 배아와 신생자를 조사하였다. 1) 췌장을 90% 절제한 어미로부터 태어난 신생자는 정상 신생자보다 생존률이 낮았지만, 살아남은 신생자의 경우에 생후 6주까지 체중을 조사하였을 때 암수 모두 정상적인 신생자와 비슷하였다. 간 조직을 조사하였을 때, 췌장을 절제한 어미로부터 태어난 신생자는 암수 모두에서 간의 이상이 발견되었다. 간에서 합성되고 소변으로 분비되는 major urinary protein(MUP)도 암컷 수컷 모두에서 그 양이 감소하였는데, 간조직의 이상을 뒷받침하고 있다. 2) 췌장을 부분절제한 어미에서 남아있는 췌장내의 랑게르한스 섬이 커져 있었으며, 간조직도 이상이 생긴 것으로 나타났다. 그러나 췌장을 부분절제한 어미의 경우에 혈당 수준은 대조군과 차이를 보이지 않았다. $Inhibin-{\alpha}$가 과발현된 생쥐에서 태어난 신생자의 경우에 저체중과 생존률 저하가 나타나고 있는데, 당뇨병 신생자와 유사한 점이 매우 많다. 이에 DNA 주사법으로 $inhibin-{\alpha}$의 과발현을 유도한 후에 어미 자신의 변화를 조사하였는데, $inhibin-{\alpha}$를 과발현시킨 생쥐에서 랑게르한스 섬이 작아졌지만, 혈당 수준은 대조군과 차이를 보이지 않았다. 종합하면, 췌장의 부분절제는 신생자와 배아 모두에게 영향을 미치고 있었고, 어미 자체에도 심각한 영향을 주고 있었다. 그렇지만 조사한 기간 내에서 산모의 혈당 수준은 변하지 않은 것으로 나타났다. 당뇨병 산모와 배아 및 신생자와의 관계는 매우 복잡한 것으로 추정된다.

본 연구는 최근 20년간의 치료순응도 관련 국내연구를 수집하여 연구 동향을 파악하고, 계량적 메타분석을 통하여 순응도 향상을 위한 개입 효과를 산출하여 제시하고자 하였다. 연구 결과는 다음과 같다. 첫째, 1980년대 이후 20여년간 치료순응도와 관련된 연구는 133편에 달하였다. 이중 순응도 향상을 위한 실험연구가 11.3%, 단면연구 및 전향적 관찰연구가 88.7%에 해당하였으며, 후자의 경우 주로 순응도 향상 관련 요인에 관한 연구들이었다. 둘째, 연구대상의 상병 종류는 고혈압이 전체 연구의 24.1%로 가장 많았고, 다음으로 기타 만성질환, 당뇨병 및 결핵의 순으로 주로 이환기간이 길고 완치가 어려워서 치료순응도에 많은 노력을 기울일 필요가 있는 질환들이었다. 셋째, 133편 논문의 질적 메타분석과정을 거쳐 선별기준에 부합되는 논문은 10편으로 순응도 측정은 고혈압의 경우 혈압 조절과 같은 건강효과를, 당뇨병의 경우 뇨당, 혈당 저하와 같은 직접적인 지표 측정의 방법을 측정하였고, 이외에도 약속 이행과 환자의 주관적 보고, 약물 복용이행과 같은 객관적 지표를 측정하였다. 한편 개입방법으로는 행동변화를 적용한 1편의 연구 이외에 교육적, 행동적 및 정서적 개입의 방법을 모두 병행하여 적용하고 있었다. 넷째, 이들 중 6편의 논문에 대하여 순응도 향상에 대한 개입의 통합효과크기를 산출한 결과, 개입을 하지 않은 군에 비하여 개입이 이루어진 경우에 치료순응도 향상 효과는 4.1192여서 커지는 것으로 나타났다. 이를 다시 순응도 측정방법으로 구분하여 분석한 결과, 치료 순응도를 건강결과(혈압)로 측정한 경우 개입으로 인한 유효크기는 0.4679였고, 직접 측정지표(혈당/뇨당)에 의한 경우 개입 후 유효크기는 0.7753으로 나타나 순응도가 향상되었음을 알 수 있다. 이상의 결과에서 다양한 개입활동들이 환자의 치료순응도를 향상시키는 데 기여할 수 있음을 제시할 수 있다. 그러나 계량적 메타분석 기준에 부합되는 연구의 논문 수가 제한적이라는 한계점이 있으며, 연구에 사용되는 개입방법의 시도가 더욱 다양화될 필요성이 제시되고 있어 향후 이와 관련된 많은 연구들이 활성화되기를 기대한다.
