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.

Purpose: To improve professional intensive care by analyzing admission causes, causes of death, disease conditions, and treatment processes in patients with hematological malignancies admitted to intensive care units (ICUs) in South Korea. Methods: This was a retrospective study approved by IRB, and conducted on admission with 559 adults, in the hematology ICU of a hospital located in Seoul. The study was carried out from April 2009 to March 2012. Data were analyzed using SAS. Results: Pneumonia was the most frequent cause of ICU admission and death, followed by sepsis. The condition at discharge was death (53.6%), recovery (39.9%), or hopeless (5.1%). Mortality of patients in states of incomplete remission was higher than that of patients with complete remission and of patients with multiple myeloma, severe aplastic anemia, and lymphoma. Conclusion: Results show that pneumonia and sepsis are the most frequent causes of ICU admission and for the death of patients with hematological malignancies. The most frequent status at discharge of patients with hematological malignancies was death (53.6%), with mortality of patients at Incomplete Remission status, of mechanically ventilated patients, and of patients on continuous renal replacement therapy (CRRT) being higher than others.

Yang deficiency pattern is a representative syndrome differentiation. This article is a study on to which categories of modern diseases yang deficiency is assigned by reference to modern clinical papers and the meaning of yang deficiency interpreted with a perspective of Korean Medicine and a modern perspective. Yang deficiency, yang qi deficiency, lack of yang qi and yang qi debilitation are the words found in "Nei Ching" and yang qi can be interpreted as something to warm, drive and arouse. Zhangzhongjing considered recovery or loss of Yang as the key to life in "Shanghanlun". Danxi proposed "Yang being liable to hyperactivity, Yin being insufficient" and emphasized pathological ministerial fire of Yang exuberance rather than physiological ministerial fire of Yang deficiency. Zhangjingyue proposed "Yang not being in excess, Yin being often deficient" and understood growth and decline of yin qi are all led by yang qi and put emphasis on true yin in addition to yang qi. Diseases of yang deficiency pattern are related with decline of metabolic level, hypofunction of internal secretion, disorder of immune function, disorder of automatic nerve system, sympathetic nerve inhibition, metabolic disorder of microelements, increase of cGMP, change of microcirculation, low speed of blood stream, kidney malfunction. Diseases related with kidney are sterility, polycystic ovary syndrome, spinal stenosis, edema, renal failure, IgA nephropathy, erectile dysfunction, nephritis, prostatitis, benign prostatic hyperplasia, decrease of adrenal cortical hormone by nephrotic syndrome, myelodysplastic syndrome. Disease related with heart are heart failure, arrhythmia, cardiomyopathy, atherosclerosis heart disease, hypertension, hyperlipidemia, pulmonary heart disease. Diseases related with spleen are irritable bowel syndrome, ulcerative colitis. Diseases related with liver are hypothyroidism, liver cirrhosis ascites, hepatitis B, chronic hepatitis, hepatic diabetes. Diseases related with lung are allergic rhinitis, cough variant asthma, bronchial asthma, pulmonary emphysema. And diabetes mellitus, metabolic syndrome, aplastic anemia, headache, encephalatrophy, Alzheimer's disease are also related with yang deficiency.

In the early days of open heart surgery, acute respiratory failure following extracorporeal circulation was a significant deterrent to an uncomplicated recovery. Although a marked improvement in prevention and treatment of postoperative respiratory failure has been achieved, the problem has not been completely eliminated and continues to be a causative factor in morbidity and mortality Fates following open heart surgery. We have attempted to evaluate postoperative respiratory failure in patients undergoing cardiac operation with the aid of extracorporeal circulation. Our series comprised 92 patients who underwent elective open heart surgery at the Department of Thoracic and Cariodvascular Surgery, School of Medicine, Kyungpook National University, from January, 1980 to December, 1982. In our study, the overall incidence of acute respiratory failure following open heart surgery was 18.8 percent. The duration of extracorporeal circulation in a series of 18 patients who developed postoperative respiratory failure [Group B] was longer in the mean value [120.3 minutes] than the uncomplicated 74 patients [Group A] [85.8 minutes]. The duration of artificial ventilation after open heart surgery in Group A averaged 13.4 hours as contrasted with 76.5 hours in Group B. In Group B, the inspired oxygen concentration [FiO2] in artificial ventilation was continued in the higher level than Group A until 18 hours after operation. Upon pulmonary function test performed pre-and postoperatively, residual volume[RV], RV/TLC and FEV 1.0/FVC were remained essentially unchanged following extracorporeal circulation, whereas forced vital capacity [FVC], FEV 1.0 and FEF 25-75% were significantly decreased in the early postoperative days. The incidence of acute respiratory failure was significantly higher in a series of patients who developed postoperative complications, such as re- exploration due to massive bleeding, low cardiac output, acute renal failure and arrhythmias. A total of 9 patients died, giving an overall mortality was 33.3 percent whereas the mortality was only 1.1 percent for patients without respiratory failure.

Sodium retention is a hallmark of nephrotic syndrome. We investigated whether sodium retention is associated with changes of natriuretic peptide system at different stages (i.e., a sodium retaining stage and a compensatory stage) of nephrotic syndrome. At day 7 after PAN(puromycin aminonucleoside) injection, the urinary excretion of sodium was decreased, along with the development of ascites and positive sodium balance. The plasma and urinary ANP(atrial natriuretic peptide) immunoreactivities were increased. ANP mRNA expression was increased in the heart and kidney, whereas that of NPR(natriuretic peptide receptor)-A and NPR-C mRNA was decreased in the kidney. The expression of NEP was decreased in the kidney. At day 14, urinary excretion of sodium did not differ from the control. The plasma ANP level and heart ANP mRNA expression returned to their control values. The expression of ANP mRNA in the kidney was increased in association with increased urinary ANP immunoreactivities. The expression of NPR-A in the kidney became normal, whereas that of NPR-C kept decreased. The expression of NEP(neutral endopeptidase) remained decreased. These findings suggest that the increased renal ANP synthesis in association with decreased metabolism via NEP and NPR-C may play a compensatory role against the development of sodium retention in nephrotic syndrome. The decreased of NPR-A expression in the kidney may contribute to the ANP resistance at day 7. The subsequent recovery of NPR-A expression may play a role in promoting sodium excretion in later stage(at day 14).

International Olympic Committee (IOC) prohibits the use of carteolol which is one of ${\beta}$-blockers. To prove whether carteolol product was taken or not, the analytical method in urine using GC/MS was established, and metabolism and excretion study were evaluated. As compared with acid hydrolysis, enzyme hydrolysis method was more efficiency. Coefficients of variation for intra-assay precision was around 10%. Error was less than 5% except the concentration of $0.05{\mu}g/m{\ell}$. Recovery was 78.5% at $2{\mu}g/m{\ell}$. Free carteolol, conjugated carteolol, and small amount of p-OH carteolol were found in dosed human urine samples. The conjugated form was being 59.4% of the total carteolol in human urine. The amount of carteolol renal excreted for 72 h after oral dose of 10 mg of carteolol was 49% of the administred dose.

Objectives This study was performed to decide the bone union effect of Hwaweo-jeon on tibia fractured mice. Methods In this study, laboratory experiments were implemented by the stage of in vitro and in vivo. In in vitro, MC3T3-E1 cells were treated with various concentration of Hwaweo-jeon extract (HWJ). To investigate effect of HWJ for osteoblast, relative mRNA expression of 5 substances (alkaline phosphatase [ALP], runt-related transcription factor 2 [Runx2], osteocalcin [OCN], osterix [OSX] and collagen type II alpha 1 chain [Col2a1]) was used as a marker of osteogenesis. In order to determine HWJ's effect for fracture healing, relative gene expression level of ALP, Runx2, OCN, OSX and Col2a1 were used to find out the influence to osteoblast. Furthermore, receptor activator of nuclear factor kappa-B ligand and osteoprotegerin relative mRNA expression were used to estimate the impact to osteoclast. Also, X-ray was used for the purpose of identifying bone union in tibia-fracture mouse model. Results In in vitro experiment, most part of relative mRNA expression were increased compared to control group. In in vivo and in vitro experiment, HWJ induced osteoblast activitation by verifying relative mRNA expression of 5 substances. And in vivo experiment, we can also identify that HWJ triggered osteoclast activation during early stage of tibia fracture. Furthermore, X-ray pictures show noticeable recovery of tibia fracture. Conclusions HWJ extract promotes bone union by facilitating the osteoblast. But, HWJ may occur liver & kidney toxicity over specific concentration. Therefore, when HWJ is applied to human body, doctors have to follow up the liver function test & renal function test of patient.

Hypoxemia is known to induce various physiological changes which can result in alteration in drug pharmacokinetics. To examine the effect of acute moderate hypoxemia on metoclopramide (MCP) pharmacokinetics, a continuous 14-hour infusion of MCP during a normoxemic, hypoxemic and subsequent normoxemic period was conducted in eight adult sheep. Arterial blood and urine samples were collected to examine the effects on the pharmacokinetics of MCP and its deethylated metabolites. MCP and its mono- and di-deethylated metabolites were quantitated using a GC/MS method. Steady-state concentrations of MCP were achieved in each of the three periods. During hypoxemia, MCP plasma steady-state concentration increased significantly from 50.72$\pm$1.06 to 63.62$\pm$1.79 ng/mL, and later decreased to 55.83$\pm$1.15 ng/mL during the post-hypoxemic recovery period. Total body clearance ($CL_{TB}$) of MCP was significantly decreased from 274.2$\pm$48.0 L/h to 205.40$\pm$28.2 L/h during hypoxemia, and later restored to 245.8$\pm$44.2 L/h during the post-hypoxemic period. Plasma mono-deethylated MCP concentration (32.78$\pm$1.73 ng/mL) also increased, compared to the control group (21.20$\\pm$1.39 ng/mL), during hypoxemia and subsequent normoxemic period. Renal excretion of MCP and its metabolites was also decreased during hypoxemia, while urine flow was increased with a concomitant decrease in urine osmolality. Thus, the results indicate that acute moderate hypoxemia affects MCP pharmacokinetics.

Purpose The single administration of PAN(Puromycin-Aminonudeoside) to rats results in nephropathy that are similar to human minimal change nephrotic syndrome. Recently several studies indicate the pathophyslological importance of oxygen free radicals in rats with PAN-induced nephrosis. This study was conducted to evaluate the effect of $\alpha$-tocopherol, an oxygen free radical scavenger, on the histologic and biochemical changes of PAN-induced nephrosis in rats. Methods : Twenty-one Sprague-Dawley rats weighing 180-300 gm were divided into 3 groups. In group I (control group), the rats were given saline intraperitoneally for 12 days, in group II the rats were given PAN 7.5mg/100g of body weight intravenously one time and group III PAN intravenously, followed by $\alpha$-tocopherol 0.5 mg/100g of body weight jntramuscularly for 12 days. Twenty four hour urinary protein and creatinine excretion were measured on day 0, 5, 11 and 18. On the 18th day, rats were sacrificed for the determination of total serum protein, albumin and cholesterol levels. To estimate renal injuries by oxygen free radical, lipid peroxide concentration and reduced glutathione were measured in renal cortex. Histological examination in rat glomerular lesions were performed. Results : From the 5th days of PAN administration, urine protein/creatinine of group II and III were significantly increased compared the group I (P<0.05). But, urine protein/creatinine of group III was significantly lower than group II at 18th days (P<0.05). Total serum protein and albumin of group II were significantly lower than those of group III (P<0.05). Serum cholesterol of group II was significantly higher than that of group III (P<0.05). Lipid peroxide and reduced glutathione in renal cortex of group II were significantly higher than that of group I and III (P<0.05). Electron microscopic strudies of group II showed the loss of epithelial foot processes, but in group III showed preservation of epithelial foot processes. Conclusion : PAN-induced nephropathy was ameliorated significant recovery of foot process change and reduction of the urinary protein excretion by antioxidant, $\alpha$-tocopherol.

Purpose : To evaluate whether the early pulmonary irradiation can prevent or decrease the pulmonary damage and contribute to improve ultimate survival in paraquat lung. Materials and Methods : From Jun. 1987 to Aug. 1993, thirty patients with paraquat poisoning were evaluated. Fourteen of these patients were received pulmonary irradiation(RT). All of the patients were managed with aggressive supportive treatment such as gastric lavage, forced diuresis, antioxidant agents and antifibrosis agents. Ingested amounts of paraquat were estimated into three groups(A : minimal 50cc). Pulmonary irradiation was started within 24 hours after admission(from day 1 to day 11 after ingestion of paraquat). Both whole lungs were irradiated with AP/PA parallel opposing fields using Co-60 teletherapy machine. A total of 10Gy(2Gy/fr. x 5days) was delivered without correction of lung density. Results : In group A, all patients were alive regardless of pulmonary irradiation and in group C, all of the patients were died due to multi-organ failure, especially pulmonary fibrosis regardless of pulmonary irradiation. However, in group B, six of 7 patients($86{\%}$) with no RT were died due to respiratory failure, but 4 of 8 patients with RT were alive and 4 of 5 patients who were received pulmonary irradiation within 4 days after ingestion of paraquat were all alive though radiological pulmonary change. One patient who refused RT after 2Gy died due to pulmonary fibrosis. All 3 patients who were received pulmonary irradiation after 4 days after ingestion were died due to pulmonary fibrosis in spite of recovery from renal and hepatic toxicity Conclusion : It is difficult to find out the effect of pulmonary irradiation on the course of the paraquat lung because the precise plasma and urine paraquat concentration were not available between control and irradiation groups. But early pulmonary irradiation within 4 days after paraquat poisoning with aggresive supportive treatment appears to decrease Pulmonary toxicity and contribute survival in patients with mouthful ingestion of paraquat who are destined to have reversible renal and hepatic damage but irreversible pulmonary toxicity.
