This study was performed to examine the effects of Dan Jeon Breathing on depression, anxiety and fatigue of hemodialysis patients. This study used the nonequivalent control group pretest-posttest design. Before applying the Dan Jeon Breathing program, the patients were divided into the experimental group and the control group, respectively, and were requested to report their self-ratings to measure their depression, anxiety and fatigue. The Dan Jeon Breathing program was given to both groups for 60 minutes a day and 2 times a week for 12 weeks. The data collected from the program were analysed by means of ${\chi}^2$ test, Fisher's exact probability test, Shapiro-Wilk, t-test and Mann-Whitney U test. The analyses revealed that the depression (t=-2.459, ${\rho}$=.019) and anxiety (t=-2.541, ${\rho}$=.016) levels of the experimental group decreased after Dan Jeon Breathing compared to those of the control group. The difference in fatigue level was statistically insignificant (Z=-1.871, ${\rho}$=.061), though. From the above results, it was verified that Dan Jeon Breathing could be used as nursing intervention for hemodialysis patients to mitigate their depression and anxiety.

The present study was carried out to investigate the preventive effects of lamprey oil and corn oil on atherosclerotic rats induced by oral administration of cholesterol and vitamin $D_2$. The obtaind results were summarized as fellows; 1. The group, fed only the mixture of cholesterol and vitamin $D_2$ showed the significant increase of total lipid, total cholesterol phospholipid, LDL&HDL-cholesterol in the serum, triglyceride and cholesterol in the heart and the aorta, but the significant decrease of triglyceride in the liver, as comparing with normal control group (p<0.05). The aorta showed the severe damage of disorganization, calcification, necrosis and lipid deposition in the aortic wall. 2. The group, adminstered the mixture of cholesterol and vitamin $D_2$ and fed 15% lamprey oil diet, showed the significant decrease of total lipid, triglyceride, total cholesterol, phospholipid and LDL&VLDL-cholesterol in the serum, triglyceride and cholesterol in the heart and the aorta, but the significant increase of cholesterol in the liver, as comparing with atherogenic control group (p<0.05). The aorta showed slight calcification and no lipid deposition in the aortic wall as comparing with atherogenic control group. 3. The group, administerd the mixture of cholesterol and vitamin $D_2$ and fed 15% corn oil diet, showed the decrease of total lipid, triglyceride and VLDL-cholesterol in the serum, and triglyceride in the heart and the aorta, as comparing with atherogenic control group (p<0.05). The aorta showed calcification and no lipid deposition in the aortic wall. In reviewing above results it was concluded that lamprey oil and corn oil in polyunsaturated fatty acids had the preventive effect on atherosclerotic rats induced by cholesterol and vitamin $D_2$. And the effect of lamprey oil in n-3 polyunsaturated fatty acids was higher than that of corn oil rich in n-6 polyunsturated fatty acids.

This study was performed to evaluate the efficacy of sodium carboxymethylcellulose (SCMC) for the prevention of postoperative uterus and ovary adhesion formation in the Korean black goats. Twenty adult female Korean black goats randomly were divided into five groups with four animals in each group. After the routine laparotomy, catheter for injection was inserted into the abdomen. Before abdominal closure, saline, 1% SCMC, 2% SCMC or 0.4% HA solution (50ml/10kg of body weight/head) were injected in the abdominal cavity in each group. Three weeks after surgery, second laparotomy was performed and the adhesions were scored on a scale of 0 to 10 according to their vascularity and adhesion size in uterus and ovary. This trial was repeated the four times with the interval of three weeks. In the first and second trial, the group treated with 2% SCMC significantly reduced the adhesion formation than other treatment groups (P<0.05). In the third trial, the adhesion formation was significantly reduced in 2% SCMC and 1% SCMC (P<0.05). In the fourth trial, 2% SCMC reduced the adhesion formation. However, there was no significant difference among other groups. This study showed that the 2% SCMC administered at the end of the surgery reduced the adhesion formation in the Korean black goats.

To study the effect of toluene administration on the liver damage, rats were previously fed a low (casein 7%, LP) or standard(casein 20%, SP) protein diet and for four days toluene(50% in olive oil) was given at 0.2ml/100g body weight/day to the male rats, and then the degree of liver damage in toluenetreated animals fed LP were compared with those fed SP. The increasing rate of liver weight/body weight and the serum levels of xanthine oxidase to the control group were higher in rats fed SP than those fed LP. The decreasing rate of protein contents in cytosol, mitochondria and glycogen, glutathione contents of liver to the control group were higher in rats fed SP than those fed LP. In histopathological findings, the swelling of hepatic cell around the central vein was demonstrated in all the two groups toluene-treated rats. But the degree of swelling severity in hepatocytes was somewhat higher in rats fed SP than those fed LP. Therefore it is assumed that the degree of liver damage severity in toluenetreated animals was higher in rats fed SP than those fed LP.

The effects of electroacupuncture (EA) at SP-6 with different durations on the minimum alveolar concentration (MAC) and on the cardiovascular system were evaluated in dogs under isoflurane anesthesia. Eight healthy male beagles were randomly assigned to four study groups (n = 5/group) with washout period of 7 days for recovery and anesthetic withdrawal between experiments. Four study groups were control, nonacupoint electrical stimulation (NA), EA for 30 minutes (SP-6) and continuous EA for 70 or 90 minutes (SP-6C). For the nonacupoint electrical stimulation group, needles were inserted into the nonacupoint at the muscle bellies of left triceps brachii and right quadriceps femoris. MAC and cardiovascular parameters were determined after EA at SP-6 acupoint and at nonacupoint. Thirty minutes of EA and continuous EA until re-determination of MAC at SP-6 acupoint lowered the MAC of isoflurane by 21.3$\pm$8.0% and 16.1$\pm$4.6%, respectively (p<0.05). The decrements in MAC values were not significantly different between two EA groups. However, electrical stimulation of nonacupoint did not induce a significant change in MAC. In SP-6 and SP-6C groups, significant changes in cardiovascular parameters were not observed. These results indicate that EA at SP-6 have an advantage in isoflurane anesthesia in terms of reducing the requirement for anesthetics and minimizing cardiovascular side effects. EA for 30 minutes at maximum might be the sufficient time to produce acupuncture analgesia.

Purpose : Transforming growth factor (TGF)-${\beta}1$ reportedly increases neuronal survival by inhibiting the induction of inducible nitric oxide synthase (NOS) in astrocytes and protecting neurons after excitotoxic injury. However, the neuroprotective mechanism of $TGF-{\beta}1$ on hypoxic-ischemic (HI) brain injury in neonatal rats is not clear. The aim of this study was to determine whether $TGF-{\beta}1$ has neuroprotective effects via a NO-mediated mechanism and N-methyl-D-aspartate (NMDA) receptor modulation on perinatal HI brain injury. Methods : Cortical cells were cultured using 19-day-pregnant Sprague-Dawley (SD) rats treated with $TGF-{\beta}1$ (1, 5, or 10 ng/mL) and incubated in a 1% O2 incubator for hypoxia. Seven-day-old SD rat pups were subjected to left carotid occlusion followed by 2 h of hypoxic exposure (7.5% $O_2$). $TGF-{\beta}1$ (0.5 ng/kg) was administered intracerebrally to the rats 30 min before HI brain injury. The expressions of NOS and NMDA receptors were measured. Results : In the in vitro model, the expressions of endothelial NOS (eNOS) and neuronal NOS (nNOS) increased in the hypoxic group and decreased in the 1 ng/mL $TGF-{\beta}1-treated$ group. In the in vivo model, the expression of inducible NOS (iNOS) decreased in the hypoxia group and increased in the $TGF-{\beta}1$-treated group. The expressions of eNOS and nNOS were reversed compared with the expression of iNOS. The expressions of all NMDA receptor subunits decreased in hypoxia group and increased in the $TGF-{\beta}1$-treated group except NR2C. Conclusion : The administration of $TGF-{\beta}1$ could significantly protect against perinatal HI brain injury via some parts of the NO-mediated or excitotoxic mechanism.

This study was done to examine the effect of 'Zippy's friends' program based on stress coping model for early child. A nonequivalent control group was designed to conduct a pre-post test for this study. The participants for this study were 148 first grade elementary school students in G city(experimental group=72, control group=76). The experimental group received 'Zippy's friends program for 24 weeks (6 module, 24 hours). The control group did not receive any treatment. From April to December 2017 data were collected using self-report structured questionnaires, and were analyzed using the ${\chi}^2$-test, t-test, and ANCOVA with SPSS/WIN 20.0 Program. After the treatment, significant differences were found between the experimental group and control groups in terms of stress coping ability( F=22.77, p<.001),but not in level of emotional intelligence (t=-.37, p=.715). Results of this study indicate that Zippy's program can be used in school based practice as an effective mental health intervention for early child.
