Background : Hemorrhagic shock and trauma are two of the most common causes of acute lung injury. The activation of cyclooxygenase is one of the important causes of acute lung injury. This study investigated the effect of aspirin, a well-known cyclooxygenase inhibitor, on severe hemorrhage-induced acute lung injury in rats. Methods : The hemorrhagic shock was induced by withdrawing blood; 20ml/kg of B.W., through the femoral artery in 5 min. The mean arterial pressure was recorded through the femoral artery on a polygraph. Results : In the present investigation, the lung tissue myeloperoxidase activity, protein contents and leukocyte counts, in bronchoalveolar lavage fluid, increased significantly 2 and 24 h after the hemorrhage induction. Although the decreased mean arterial pressure spontaneously recovered, acute lung injury occurred after severe hemorrhage. These changes were effectively prevented by a single intravenous injection of aspirin (10 mg/kg of B.W.) 30 min before the hemorrhage. Conclusion : These results suggest that severe hemorrhage-induced acute lung injury is mediated, in part, by the activation of cyclooxygenase. Furthermore, pretreatment of aspirin in acute lung injury-prone patients, or prophylactic treatment of aspirin to the patients with precipitating conditions, could be helpful in the prevention of acute lung injury.

Objectives: The present study was undergone to determine whether Glycyrrhizae Radix pharmacopuncture intravenous injection exerts beneficial effect against the ischemia-induced acute renal failure in rabbits. Methods: Rabbits were treated with Glycyrrhizae Radix pharmacopuncture via i.v., followed by renal ischemia/reperfusion. The fractional excretion of glucose and phosphate were measured and the malondialdehyde content was also determined. The morphological changes of cortical part of kidney also observed with light microscope. Results: Renal ischemia/reperfusion caused increase of the fractional excretion of glucose and phosphate in ischemia-induced animals, which was prevented by Radix Glycyrrhizae extract treatment. Ischemia/reperfusion increased lipid peroxidation, which was prevented and morphological changes also altered by Radix Glycyrrhizae pharmacopuncture administration. Conclusions: These results indicate that lipid peroxidation plays a critical role in ischemia-induced acute renal failure and Glycyrrhizae Radix pharmacopuncture exerts the protective effect against acute renal failure induced by renal ischemia/reperfusion.

This study was conducted to investigate the effects of epinephrine and norepinephrine on basal gastric acid secretion and plasma gastrin and secretin concentration in the conscious rat. One hundred and eighty-four albino rats with gastric cannula were used after 18 hours or more of fast, with water ad libitum. In a restraint cage for collection of gastric juice, physiological saline (0.9% NaCl) was continuously infused into the jugular vein through a catheter for one hour at a rate of 1 ml/hr (control period). Immediately after the control period, epinephrine (1, 2, 4, 8 and $16{\mu}g/ml/hr)$, norepinephrine (1, 2, 4, 8 and $16{\mu}g/ml/hr)$ or physiological saline (1 ml/hr) was infused for another one hour. Gastric juice was collected at one hour interval for two hours infusion period. Adrenergic antagonists, phentolamine and propranolol were injected into the jugular vein 5 min prior to the infusion of epinephrine or norepinephrine at a dose of 0.2 mg/0.1 ml. Blood was sampled from the jugular vein for the radioimmunoassay of plasma gastrin and secretin after the collection of gastric juice. The results were as follows: 1) Both epinephrine and norephinephrine significantly increased gastric acid output in a dosedependent manner. 2) The effects of epinephrine and norepinephrine on the gastric acid secretion were antagonized by the pretreatment with phentolamine and propranolol. 3) Plasma gastrin and secretin concentrations were not significantly affected by the intravenous infusion of epinephrine and norepinephrine. It can be inferred from the above results that epinephrine and norepinephrine facilitate gastric acid secretion in conscious rats and the mechanism of which is attributed to ${\alpha}\;and\;{\beta}$ adrenergic receptors rather than gastrin and secretin.

When injecting intravenously of CT inspection, the effusion of the contrast meium can induce the tissue damage with the blood vessel outside. We detect extravasation which is generated in the course where we inject the contrast medium into the blood vessel. And we use the bolus tracking system for the detection of that. By using MPR and VR images, moreover we detected the extravasation in order to prevent the tissue damage. In order to detect the effusion of the contrast medium, we used 16-MDCT and 64-MDCT. Three dimensional images about the outflow of the blood vessel can provide the treatment information which is important in the patient treatment. Moreover we applied the image processing technique in order to improve sharpness between contrast media and organization. And sharpness and contrast was improved.

This is a convergence study about influences of hematopoietic stem cell transplantation on children growth. For this explanatory survey research, data were collected with medical record of 112 children with malignant and hematological diseases received HSCT from February to March, 2009. To analyze the growth after HSCT, mixed-effects model was used. The mean SDS of height and weight were negative values in HSCT. The mean value of SDS were significantly lower in autologous HSCT group by height(p=0.0008) and weight(p= 0.0012). Significant factors on changes of SDS of height growth were age at HSCT(p=0.0251), autologous HSCT(p=0.0020) and total dose of steroid in allogeneic HSCT (p=0.0403) and age at HSCT(p=0.0042), autologous HSCT(p=0.0035), and duration of TPN(p=0.0159) for weight growth. According to the results, we must learn to recognize the predicting growth impairment after HSCT in children. regarding nursing interventions should be conducted in the care of these children.

Background : This study was conducted to evaluate the effects of wild ginseng herbal acupuncture developed for the intravenous use. Healthy male and female volunteers(n=57) went through Randomized Control Trials(RCT). Methods : For those who are under a medication due to common cold or other illnesses were excluded in the primary stage and the subjects with possible abnormalities in the pre-screening process were also excluded in the secondary stage. Then the examination groups were determined by random sampling. Experiment groups were divided into Normal saline injection group(control group), cultivated wild ginseng herbal acupuncture group(experiment group 1) and natural wild ginseng herbal acupuncture group(experiment group 2) Blood tension, body temperature, pulse, and other criteria were measured and analyzed. Results : 1. Intravenous injection of cultivated wild ginseng herbal acupuncture and natural wild ginseng herbal acupuncture didn't cause significant changes in the blood tension, pulse, body temperature, and etc. 2. No significant differences were witnessed in CBC, ESR, biochemistry of blood test and UA between the experiment groups. 3. No significant changes were noted in the thermography before and after the test in the experiment groups. 4. Some of the common physical changes occurring during and after the administration were fatigue, chest distension, and headache in all of the experiment groups. 5. Comparing general condition after one week from the termination of administration, the control group showed worst condition while as the natural wild ginseng herbal acupuncture group displayed best condition. Conclusion : From the above results, we can carefully deduce that the intravenous injection of the wild ginseng herbal acupuncture didn't show significant differences compared to injection of the normal saline. We can infer it is safe on the human body and further studies and reports must be followed.

Despite their sometimes fatal complications such as respiratory depression when used for postoperative pain control, intravenous and epidural narcotics remain the mainstay of treatment regimens. Because of the problems, anesthesiologists are seeking alternatives. We compared the analgesic effect and complications of continuous intravenous morphine with ketorolac. Ketorolac is a non-steroidal agent with potent analgesics and moderate anti-inflammatory activity. Forty ASA physical status I or II patients were given morphine(20 patients) or ketorolac(20 patients):In the morphine group, an initial bolus dose of 2 mg i.v. was given followed by continuous infusion at a rate of 1 mg/hr for 48 hours. The ketorolac group was given initial bolus of 30 mg i.v. This was followed by continuous infusion at a rate of 3.75 mg/hr for 48 hours using a Baxter Daymate Infuser. We checked systolic, diastolic and mean arterial pressure, heart rate, visual analogue scale(VAS) and the Prince Henry Score(PHS). This was done before the initial bolus, at 5, 15, 30 and 60 min, at 2, 6, 12, 24 and 48 hours after administration. We observed the side effects nausea and vomiting, pruritus, hypotension, somnolence, urinary retention and respiratory depression. From our study we believe ketorolac in selected patients, is as effective as morphine in alleviating postoperative pain without side effects of morphine.

Hemagglutinin (HA) titers to SRBC were chronologically observed in chickens orally inoculated at 2 days of age with 5 × 105 oocysts of Cwptosporidium bniLeWi. All the infected chickens exhibited negligible HA titers by 44 days postinoculation (Pl) . The titers were elevated as time progressed. and peaked on day 52 Pl, declined gradually thereafter, and eventually reached to normal titers on day 92 Pl. On the contrary, the titers in uninfected chickens were higher in comparison with infected chickens during the experiment. Chickens infected with the protozoa showed normal oocyst shedding profiles during this period. These data suggest that C. bnilewi infection suppress development of humoral immunity to SRBC in chickens. It is possible that impairment of the bursa of Fabricius by cryptosporidiosis rendered chickens vulnerable to other pathogens.
