The following recommendations are presented herein: All trauma patients admitted to the resuscitation room should be constantly (or periodically) monitored for parameters such as blood pressure, heart rate, respiratory rate, oxygen saturation, body temperature, electrocardiography, Glasgow Coma Scale, and pupil reflex (1C). Chest AP and pelvic AP should be performed as the standard initial trauma series for severe trauma patients (1B). In patients with severe hemodynamically unstable trauma, it is recommended to perform extended focused assessment with sonography for trauma (eFAST) as an initial examination (1B). In hemodynamically stable trauma patients, eFAST can be considered as the initial examination (2B). For the diagnosis of suspected head trauma patients, brain computed tomography (CT) should be performed as an initial examination (1B). Cervical spine CT should be performed as an initial imaging test for patients with suspected cervical spine injury (1C). It is not necessary to perform chest CT as an initial examination in all patients with suspected chest injury, but in cases of suspected vascular injury in patients with thoracic or high-energy damage due to the mechanism of injury, chest CT can be considered for patients in a hemodynamically stable condition (2B). CT of the abdomen is recommended for patients suspected of abdominal trauma with stable vital signs (1B). CT of the abdomen should be considered for suspected pelvic trauma patients with stable vital signs (2B). Whole-body CT can be considered in patients with suspicion of severe trauma with stable vital signs (2B). Magnetic resonance imaging can be considered in hemodynamically stable trauma patients with suspected spinal cord injuries (2B).

A one-year-old spayed female Korean Shorthair cat presented to Kangwon National University Veterinary Hospital with vomiting, weight loss, lethargy, loss of appetite, and polyuria that lasted for more than two weeks. The body condition score, blood pressure, heart rate, and body temperature were abnormally low, and the physical examination findings were consistent with moderate dehydration. Hematological and biochemical tests demonstrated mild azotemia and a low Na:K ratio. Additional abdominal ultrasound imaging revealed reduced size of both adrenal glands. The adrenocorticotropic hormone (ACTH) stimulation test showed decreased post-ACTH cortisol and aldosterone levels and increased endogenous ACTH levels, confirming a diagnosis of primary hypoadrenocorticism. The cat was treated with subcutaneous injections of desoxycorticosterone pivalate (DOCP) and oral prednisolone supplementation, and subsequent electrolyte analysis showed a normal Na:K ratio. Clinical symptoms were also improved in response to treatment. Hypoadrenocorticism in cats is a very rare disease, but it should not be excluded as a potential diagnosis in favor of kidney diseases or other conditions, especially when the Na:K ratio is low. In addition, the prognosis for the disease and the response to DOCP treatment should be further evaluated in cats.

A 3-year-old female Connemara pony was referred to Jeju National University Equine Hospital because of weight loss and prolonged anorexia. On admission, heart and respiratory rates were slightly elevated while body temperature was within the normal range. The color of the conjunctival and oral mucosa was yellowish pink. The blood chemistry results showed that total bilirubin, aspartate aminotransferase, and gamma-glutamyl transferase levels were remarkably elevated while blood urea nitrogen was within the reference range. Transcutaneous abdominal ultrasound revealed an enlarged right lobe of the liver with prominently increased parenchymal echogenicity, reduced hepatic vessels, and rounded caudal border. The pony was tentatively diagnosed with chronic hepatitis and icterus; rest and supportive treatments were provided. Clinical signs aggravated on day 2 with hind quarter paresis and cranial nerve signs such as circling, drooping, jerking, and head pressing against walls. Recumbency and generalized ataxia (grade 5/5) were shown on day 3. Plasma ammonia concentration on day 3 was as high as 656 µmol/L. Necropsy and histopathologic examinations strongly supported a diagnosis of hepatic encephalopathy. This case of hepatic encephalopathy exhibited rapid progress from low to terminal grade within 4 days in a Connemara pony. The results provide well-established clinical and pathological data for future application.

PURPOSE: In this study, we tried to find out what kind of exercise was more effective in sleep disorder by comparing melatonin in blood after applying low intensity with high intensity exercise to sleep disordered rats induced by experiment. METHODS: We used male Sprague-Dawley rats which were 8weeks old and weighted 300g. They were supplied with water and food without any restriction. We kept the room temperature at $25^{\circ}C$ and controld the length of day and night in 12 hours blocks, respectively. We divided the rats 60 into 2 groups. To one group we applied low intensity exercise, and to the other we applied high intensity exercise for 15minutes per day over a period of 4 weeks. We extracted the blood from abdominal aorta before, after exercise, moved into EDTA tube, performed centrifugation. We decanted the serum $200{\mu}l$ from the blood into microcentrifuge tube by samples and moved into polypropylene culture tubes with micro pipette. We split enzyme solution $50{\mu}l$ into the tubes with melatonin direct kits and make them react at $37^{\circ}C$ for 2 hours. We split assay buffer $50{\mu}l$ into each tube and mixed melatonin tracer $50{\mu}l$ and melatonin antiserum $50{\mu}l$, respectively. After we made them react in room temperature, we decanted the superficial layer with a centrifuge and measured the activity for 1 minute by competitive method with ${\gamma}$-counter equipment. We draw a standard curve through logit-log graph with CPM(counts per minute) and counted the melatonin by B/B0. We conducted independent t-test to examine the homogeneous of melatonin value of before low-intensity and high-intensity exercise. We performed paired t-test to compare before and after low-intensity and high-intensity exercise, respectively. We carried out independent t-test to compare melatonin value after low-intensity and high-intensity exercise. Significance level was .05. RESULTS: The results were as follows; firstly melatonin was more increased in the group who was exposed to high intensity exercise when we compared before to after high and low intensity exercise, respectively. Secondly, high intensity exercise was more effective than low intensity exercise when we compared the two. CONCLUSION: In conclusion, secretion of melatonin which is the material of sleep improvement could be promoted by high intensity exercise. Low intensity exercise acted as a stress rather than improving sleep and had a negative effect on the secretion of melatonin because the melatonin was affected by stress.

The importance of thyroid hormones for the survival of rats in the cold is along-established fact. Hypothyroid animals are unable to survive in a cold environment. It was also reported that acute exposure of rats, guinea pigs and rabbits to cold produced an increased secretion of TSH and thereby thyroid hormone secretion within 10 to 30 min, but this increase of thyroid activity disappeared quite rapidly during warming. However, in human study no significant difference was found in the concentration of $T_4$, TSH and cortisol between summer and winter. But plasma $T_3$ concentration was increased significantly in winter in 56 adult men. On the other hand, it has been also known that catecholamines are important in the maintenance of body temperature of rat exposured to cold. Abundant evidences suggest that the sympathetic nervous system is involved in the activation of nonshivering thermogenesis and that thyroid hormone metabolism and secretion are influenced by catecholamines and consequently by the activity of the sympatheticadrenal system. Many of the metabolic effects of catecholamines are associated with an increase in the level of cAMP mediated through activation of adenylate cyclase which converts ATP to cAMP. Other studies have shown that thyroid hormones affect the amount of adenylate cyclase present in the adipose tissue. On the other hand. it was also reported that a particulate cAMP phosphodiesterase activity in fat cells was modulated by the action of thyroid hormones. The objective of the present study was to determine the interaction between thyroid activity and cyclic nucleotides during acute exposure to cold. Albino rats weighing around 200 g were used as the experimental animal. The room temperature group was kept at $25^{\circ}C$ and the cold-exposured group was kept at $4^{\circ}C$ for 1 week or 2 weeks. Each group was subdivided into three subgroups; control, KI, and MTU group. At the end of experiment the animals were etherized and blood was taken from abdominal aorta for $T_4,\;T_3$ and cyclic nucleotides. The determinations of $T_3,\;T_4$ and cyclic nucleotides were carried out with a radioimmunoassay(RIA) method. The results were summerized as followings. 1) A significant increase of thyroid weight was observed in rats exposured to cold for 2 weeks. Furthermore, in rats administered MTU while to exposure to cold the thyroid weight was also increased significantly. 2) After 2 weeks $T_3$ concentration in the plasma of cold-exposured rats was significantly increased in KI group and MTU group as well as in control group. On the contrary, after 2 weeks of cold exposure $T_4$ level was decreased in control group. 3) In the case of cyclic nucleotides, plasma cAMP was increased in the control group after 1 or 2 weeks of cold exposure. However, cAMP level in plasma was rather significantly decreased in KI group and MTU group as well as in control group.

We implemented the Drug-Pad Moxibustion Method in order to improve the conventional moxibustion therapy. This method is aimed to eliminate burning wounds and smoke, which are the defects of conventional moxibustion therapy. And we performed to verify the efficiency by comparing the Drug-Pad Moxibustion Method with the conventional Indirect Moxibustion Therapy. We measured the body heat and the lasting time of blood circulation improvement using thermography. The moxibustion therapy has two kinds of effects: The formers are pharmacological effects of the Moxa's vasodilators and antioxidants. The latters are thermal effects which cause improvement of the blood circulation. To remove the demerits without omission of above therapeutic effects, we extracted the vasodilators and antioxidant compounds from the Moxa-$CH_2Cl_2$ fraction Moxa-EtOAc and composed the moxibustion kit with $(Ba_{0.8}\;Sr_{0.2})_{0.996}\;Y_{0.004}\;TiO_2+0.5_{WT}\;SiO_2%$ Positive Temperature Coefficients Thermistor. The experimental demonstrations have been made by the stimulating the spot which is CV4(Kwan-Won), CV8(Shin-Guel), CV12(Jung-Wan) acupuncture points of the conception vessel meridian(CV). And stimulating time was one hour. We divided the subjects into 5 groups such as no stimulation group, conventional Indirect Moxibustion group, only Drug-Pad stimulation group, only heat stimulation group, and Drug-Pad Moxibustion group. In the different cases, we have measured the body heat in pre-stimulation, just after stimulation, 2 hours after, and 4 hours after. The body heats of the group who were stimulated by the Drug-Pad Moxibustion Method were increased by over the $2^{\circ}C$. And the body heats of the group who were stimulated by the Indirect Moxibustion Method were increased by average the $1^{\circ}C$. We have evaluated that the Drug-Pad Moxibustion Method is improvement on the conventional Indirect Moxibustion Method by the heat-increasing rate is 200% and the lasting time is 150% with the body heat of the abdominal region. In the conclusions, We have implemented the Drug-Pad Moxibustion Method and evaluated the efficiency of the Drug-Pad Moxibustion Method comparing with the conventional Indirect Moxibustion Method.

서해안 금강하구의 내초도에서 1980년 7월부터 1983년 10월까지 맛조개(Solen strictus)의 생식소에 기생한 Bacciger 속 cercaria의 생활사를 구명하고자 sporocyst 및 cercaria의 형태와 발육과정, 기생률을 조사하였다. 또한 제이중간숙주 및 종숙주를 실험실에서 인공감염실험과 함께 내초도자연환경구에서 조사하여 metacercaria와 성충의 발육과정을 조사 연구한 결과 지금까지 밝혀진바 없는 Bacciger harengulae의 생활사가 구명되었다. Bacciger harengulae는 맛조개, 대합, 바지락, 띠조개가 제일중간숙주이고, 밀새우를 제이중간숙주로 하며, 종숙주는 전어, 밴댕이로 밝혀졌다. 맛조개의 생식소에 기생된 성숙한 sporocyst의 크기는 $4.0{\sim}4.3{\times}0.20{\sim}0.21$ mm이고, cercaria는 체부 $270{\times}147{\mu}m$, 미부 $270{\times}147{\mu}m$의 크기로서 꼬리 양측에 27쌍의 강모속과 1개의 강미속은 6본의 가닥으로 되어있다. cercaria의 체내에는 구흡반($52{\times}42{\mu}m$), 인두($32{\times}25{\mu}m$), 복흡반($52{\times}50{\mu}m$)과 2 개의 정소와 V자형의 배설낭이 뚜렷이 나타나며, 화염세포식은 2[(3+3)+(3+3)]=24이다. 3년에 걸쳐 맛조개에 기생하고 있는 cercaria의 평균 기생률은 $9.67\%$ 였는데, 이것은 수온의 변화와는 관계없이 연중기생된다. 기생률이 가장 높은 시기는 수온 $28.8^{\circ}C$인 7월($28.0\%$)이고, 가장 낮은 시기는 수온 $19.5^{\circ}C$인 10월($2.4\%$)이었다. 맛조개의 cercaria 기생률은 각장이 클수록 높았으며, 4.0cm 이하에서는 cercaria가 검출되지 않았다. cercaria가 성숙되는 시기는 년중 수온이 $19.5^{\circ}C$이상 상승하는 $5{\sim}10$월까지며, 수온 $19.5^{\circ}C$이하가 되면 미숙한 cercaria만이 검출된다. Cercaria는 수온 $20^{\circ}C$에서 35시간, $25^{\circ}C$에서는 29시간까지 활력이 있었으며, 생존시간은 각각 71시간, 34시간이었으나 $20^{\circ}C$이하에서는 운동력이 활발하지 못하였다. 맛조개에서 유출된 cercaria를 밀새우에 감염시킨 결과 2{\sim}3시간후에 근육에 기생하였고, 기생한 cercaria는 $7{\sim}8$시간후에 cyst를 형성하였으며, 15일이 경과되어 $420{\times}310{\mu}m$의 성숙한 metacercaria로 발육되었다. 실험실에서 수온 $20^{\circ}C$일때 밀새우의 metacercaria 감염률은 $17.0\%$ 이었고, $25^{\circ}C$때는 $61.0\%$의 높은 감염률을 나타냈으며, 감염된 부위는 제일복절, 두흉부, 제이, 삼, 오복절의 순으로 감염되었다. 내초도의 자연 서식장산 밀새우의 metacercaria 감염률은 수온 $26.5^{\circ}C$인 6월에 $9.6{\sim}11.11\%$, 수온 $28{\sim}29.5^{\circ}C$인 7,8월에는 $1.56{\sim}2.50\%$의 감염률을 나타냈다. metacercaria가 감염된 밀새우를 사육중인 전어에 먹인 결과, 20일후 전어의 장에서 $440{\sim}520{\times}310{\sim}360{\mu}m$의 성충으로 발육되었고, 성숙한 충난은 $20{\sim}24{\times}11{\sim}20{\mu}m$ 크기의 타원형이었다. 실험실에서 검출한 것과 동일한 성충이 내초도의 자연산 전어, 밴댕이에서도 체장과 관계없이 $87.3{\sim}100\%$(평균 $95.2\%$) 검출되었으며, 6, 7월에는 $100\%$ 검출되나, 8, 10월에는 $87.3{\sim}88.9\%$로 그 검출률이 낮아졌다. 전어에서 발육된 성충의 크기와 내부형태를 Yamaguti(1938)가 밴댕이에서 검출한 것과 비교한바, 동일하므로 이 흡충을 Bacciger harengulae로 동정하였다.
