Purpose: This study was to verify the effects of a fluid therapy education program for aged stroke patients for preventing dehydration, pyuria and bacteriuria. Methods: The study employed a non-equivalent control group pretest-posttest design in quasi experimental basis. Subjects were 38 stroke patients (20 in the experimental group and 18 in the control group) older than 65, hospitalized in a senior care center in S city, Korea. Results: The amount of daily average fluid intake, normal ratio of blood urea nitrogen-creatinine ratio, serum $Na^+$ and urine white blood cells were increased significantly in the experimental group. Normal ratio of bacteriuria increased in the experimental group, but not significantly. Conclusion: The education program is considered to be an effective nursing intervention tool for preventing dehydration and urinary tract infections which related to the secondary wellness of aged stroke patients. However, longer term study is necessary for better quality of nursing and developing more specific education programs for aged stroke patients usually hospitalized for a long period of time.

Purpose: This study was designed to explore the effects of providing individualized education for hemodialysis patients on their knowledge of hemodialysis, compliance of patient role behavior, and physiologic parameters. Method: A quasi experimental design with a non-equivalent control group and a non-synchronized design was used. The experiment was conducted with a total of 40 hemodialysis patients (20 in the experimental group and 20 in the control group) at the artificial kidney center, C University Hospital. The experimental group was provided with individualized education, 30 minutes per session, three times per week, for two weeks. Results: The experimental group had significantly higher knowledge of hemodialysis than the control group after the education. The compliance of patient role behavior was more enhanced in the experimental group than the control group. The experimental group showed significantly higher values of blood urea nitrogen, but not the values of blood creatinine, albumin, kalium, and phosphorus. Conclusion: The individualized education was found to be an effective intervention for improving patients' knowledge of hemodialysis and compliance of patient role behavior.

Cardiopulmonary bypass (CPB) for cardiac surgery induces the production and release of numerous chemotactic substances and cytokines, ensuing systemic inflammatory response that causes postoperative major organ dysfunctions. We performed a randomized, prospective study to investigate clinical effects of preoperative treated-methylprednisolone for preventing inflammation in pediatric cardiac surgery with CPB. Thirty pediatric patients scheduled for elective cardiac surgery were randomized to either control(n=15) or steroid group (n=15, 10 mg/kg of methylprednisolone). Arterial blood samples were taken before and after the operations for measuring total leukocyte (T-WBC) and differential counts, platelet counts, interleukin-6 (IL-6), myeloperoxidase (MPO), neuron specific enolase (NSE), troponin-I (TNI), aspartate aminotransferase (AST), alanine aminotransferase (ALT), blood urea nitrogen (BUN), and creatinine levels. Postoperative parameters such as pulmonary index (PI, $PaO_2/FiO_2$), 24 hrs and total bleeding volumes, mechanical ventilating (MVP) and intensive care unit (ICU)-staying periods, and hospitalization were assessed. T-WBC, neutrophil fraction, IL-6, MPO, NSE, TNI, AST and creatinine levels, bleeding volumes, PI, and MVP at the postoperative periods were lower or shorter in steroid group than in control group (P<0.05). These findings indicated that preoperative administration of methylprednisolone attenuated CPB-induced inflammatory reactions, contributing to postoperative recovery of patients underwent cardiac surgery.

Thirty Holstein calves were used to determine effects of age, environment and sex on blood metabolite concentrations during 1 to 90 d of age. Calves were weaned at 75 d of age. Environmental effects are grouped by the difference in month at birth and site of feeding. Blood samples were obtained every 2 or 3 d. The mean metabolite concentration every 3 d was used for the statistical analysis. Dairy bodyweight gain was not affected by environmental group and sex effect. Concentrations of plasma glucose, nonesterified fatty acids (NEFA), triglyceride, total cholesterol and total ketone changed with growth. These developmental changes in metabolite levels would be caused by ruminal maturation with increment of grain intake. Levels of plasma urea nitrogen, glucose, NEFA, triglyceride and total cholesterol drastically changed during a few weeks after birth, indicating that the physiological state in calves greatly changed during that time. Effects of the environmental group and sex were significant in almost all metabolites. Temperature influenced plasma metabolite concentrations. The plasma metabolite concentrations were affected more intensely by heat stress in the infant period than in the neonatal period.

Mold growth decreased nutritive value of wheat straw (WS). Mold increased DM (94 vs 98%) and ADF (51 vs 56%) contents and had no effect on natural detergent fiber (NDF). Crude protein and N values were decreased in moldy wheat straw, Mold increased insoluble N content of wheat straw (WS) from 21 to 27%. Ammoniation increased the CP of nonmoldy straw from 3.8 to 8.3% and moldy straw from (3.3 to 6.2%). Aspergillus and zygomycetes fungal species were most prevalent and total numbers were higher on moldy straw. Ammoniation decreased total numbers of fungal spores on nonmoldy and moldy WS. Ammoniation of moldy WS increased (p < 0.10) feed in take (1.8%) as compared with nonmoldy, ammoniated, nonmoldy and moldy WS. Steers fed moldy WS had lowest (p < 0.10) feed intake (1.3% of BW daily) compared with other diet. There was little difference (p < 0.10) in intake of nonammoniated vs. ammoniated WS. Steers fed moldy straw lost 6 kg BW. Ammoniated, nonmoldy straw elevated Blood Urea Nitrogen (BUN) (10.5 mg/dl). Alkaline Phosphatase (ALK) was greater in steers fed moldy VS nonmoldy straw (148 VS 95 U/liter. p < 0.10).

납중독에 대한 마늘의 antidotic effect를 조사하기 위한 4주간의 실험에서 , rat 체중 kg 당 중 (7일간) 1회초산납 100mg을 투여한 rat에 매일 마늘즙을 식이의 4%로 투여한 실험군(LG)과 초산납과 함께 중금속 해독제인 N-acetyl penicillamine을 매일 rat 체중 kg당 100mg 투여한 실험군 (LP)의 체중 증가율 비교에서 초산납만을 투여한 실험군(L)보다 LG군과 LP군 모두 유의성 있는 rat 성장률 개선효과 (각각 +13.3%과 +22.3%)를 보였다. L군 rat의 외관과 해부검사에서는 장기들(위, 간장, 신장)의 병변(damage)이 매우 미미하게 관찰되었으나 혈액검사에서 GOT, alkaline phos-phatase, blood uric acid, blood urea nitrogen, crea-tinine, bilitrubin 값이 유의적을 증가하여 납중독에 의한 장기(organs) 특히 신장 기능의 현저한 장해를 보였다. 그러나 LG군이 이들 측정값이 L군보다 유의성의 차로 낮은 값을 보여 LP군과 거의 비슷한 수준이었다. 특히 L군에서는 Pb 중독으로 인하여 hemo-globin 량이 정상 이하(10.37g/dl)로 감소되었으나 LG군에서는 L군에서와 같이 거의 정산 (12.32g/dl)을 유지하였다. L군의 혈액, 간장 및 신장의 납 합량은 각각 0.281, 0.250, 0.403ppm으로 대조군 보다 매우 높았으나 LG군은 대조군에 가깝게 그리고 LP군과는 거의 같은 수준(각각 0.182, 0.131, 0.253ppm)으로 낮아졌다. 이상의 실험 결과에서 마늘이 rat의 납중독에 미치는 효과를 N-acetyl penicillamine의 해독 효과와 비교할 때 마늘의 해독 효과라고 볼 수 있는 유의성있는 측정값들이 관찰되었다.

To investigate the recorded efficacy in Oriental medical references and effects in clinics, experimental studies were undertaken to estimate 'Palmiwhan' to the diuretic effect in normal rats, rabbits and rats with $HgCl_2-induced$ acute renal failure and hypotensive effects on the nephrogenous hypertension in rabbits with $HgCl_2-induced$ acute renal failure. The results of this study were summarized as follows; Increase in urinary volume, urinary $Na^+\;and\;Cl^-$ excretions were significantly recognized in normal rats and rabbits. Increase in urinary volume, urinary $Na^+\;and\;Cl^-$ excretions were significantly shown in rats with 2mg/kg $HgCl_2-induced$ acute renal failure. Although plasma electrolyte and creatinine levels were little affected, plasma urea nitrogen levels were significantly elevated in normal rats and 2mg/kg $HgCl_2-induced$ acute renal failure of rats. Although the blood pressure was not affected in normal rabbits and cats, hypotensive actions due to the diuretic effect were recognized in rabbits $HgCl_2-induced$ acute renal failure.

The aim of this study was to evaluate the anti-diabetic effects of the water extract of Lespedeza cuneata (LCW) using rat insulinoma (RIN) m5F cells and streptozotocin (STZ)-induced diabetic rats. The effect of LCW on the protection of pancreatic beta cells was assessed using MTT assay, and nitric oxide production was assessed using Griess reagent. STZ-induced diabetic rats were treated with 100 and 400 mg/kg body weight of LCW for 5 weeks. In results, LCW significantly protected cytokine-induced toxicity and NO production, and increased insulin secretion in RINm5F cells. LCW significantly decreased serum blood glucose, thiobarbituric acid reactive substances (TBARS), blood urea nitrogen (BUN) and advanced glycation end products (AGEs) levels, and renal fibronectin expression in STZ-induced diabetic rats. Also, LCW effectively improved BW loss in STZ-induced diabetic rats. Thus, our results suggest that LCW has a beneficial effect on cytokine-induced pancreatic beta cell damage and biomarkers of diabetic complication in hyperglycemic rats.

Objectives : The aim of this study was to investigate the effect of Jaeumyangyung-tang(滋陰養榮場(JY), JA-0.65g/kg;JB-1.3g/kg) on hyperglycemic mice induced with streptozotocin(STZ). Methods : The experiment operated for 6 weeks. The rats were divided into 3 groups : diabetic group(control group), diabetic group treated with JA(0.65g/kg) for 6 weeks, and diabetic group treated with Jb(1.3g/kg) for 6 weeks. Results : In the STZ-induced diabetic group, blood glucose levels significantly increased as well as the loss of body weight. The levels of serum glucose decreased significantly (p<0.05 or p<0.01) in the JA and JB groups compared with the control. According to a tolerance test, intraperitoneal glucose was ameliorated in the JA and JB groups. The blood urea nitrogen (BUN) and creatinine levels slightly decreased. Histologic analyses of the pancreases revealed that the ${\beta}-cells$ on Langerhans' islets were destroyed by STZ, but the ${\beta}-cell$ mass was larger in the JY than in the control mice. Conclusions : These results indicate that JY can exert beneficial effects on diabetes. preservation of in vivo ${\beta}-cell$ function and regeneration of ${\beta}-cell$ dysfunction by STZ.

The diagnostic method was, evaluated in experimentally induced acute renal failure in doges. Ten male dogs weighing from 5 to 10 kg were assigned to two groups(gentamicin & ethylene glycol treated group) al random. Gentamicin sulfate at 10 mg/kg of body weight, t.i.d., for 7 days and ethylene glycol at 3 ml/kg of body weight once used in a randomized complete block design with tee treatments in block. The samples(blood, urine) were collected before and 1,3,5,7,9 and l1th day after administration. The serum creatinine concentration and BUN(blood urea nitrogen) were sig- nificantly increased at the 7th day than before administration in gentamicin treated group (p<0.05), bolt there was significant increase at the 1st day than before administration in ethylene glycol treated group(p<0.05). The urine GGT(gramma glutamyl transpeptidase) and GGT/creatinine were significantly increased at the 1st (lay after administration in gentamicin treated group (p<0.05). But in ethylene glycol treated group, there was no significant changes. The value of FENa (fractional excretion of sodium) was significantly increased at the 3rd day after administration in gentamicin treated group and the 1 st day after administration in ethylene glycol treated group (p<0.05). These results suggest that FENa was a good parameter of renal function in dogs with acute renal failure.
