Small cell lung carcinoma (SCLC) is a cancer that shows aggressive behavior, early spread to distant sites, and frequent association with distinct paraneoplastic syndromes. Spontaneous remission of cancer, particularly of SCLC, is a rare biological event. Cases involving spontaneous regression of SCLC were reported, and were associated with paraneoplastic syndromes of the nervous system. This article reports on a 78-year-old man with SCLC in remission, with neurological symptoms. The patient visited the hospital because of generalized weakness, and imaging studies revealed a mass in the lower lobe of the left lung, pathological evaluation showed SCLC. The patient refused oncologic treatment and was treated only with conservative care. In follow-up study the diameter of the mass had decreased from initial 32 mm, 9 months after admission to 20 mm, 17 months after admission to 13 mm. The patient kept complaining of generalized weakness, dizziness, and paresthesia of limbs. We assumed that, in this case, the spontaneous remission of lung cancer was related to the immunologic response directed against the tumor, which is believed to be an important factor in the pathogenesis of paraneoplastic neurologic syndromes.

By comparing ‘Jing Mai(${\ulcorner}$經脈${\lrcorner}$)’ and ‘Jin Fu(${\ulcorner}$禁服${\lrcorner}$)’, we are able to see that ‘Jing Mai’ has adopted many of its aspects from ‘Jin Fu’, which also enables us to conclude that ‘Jing Mai’ was made after 'Jin Fu', with the 'Ren Ying Cun Kou Mai Fa(人迎寸口脈法)‘ being considered important. 'Jing Mai' was made relatively late, during the last days of 'Xi Han(西漢)' or early days of 'Dong Han(東漢)'. Also 'Jing Mai' was written after 'Ying Qi(${\ulcorner}$營氣${\lrcorner}$)’. ‘12 Jing Mai’ in ‘Jing Mai’ is based mainly on 'Yin Yang Shi Yi Mai Jiu Jing(${\ulcorner}$陰陽十一脈灸經${\lrcorner}$)‘ and has also referred to other meridian theories, modifying it again by theories of 'Jin Fu' and 'Ying Qi', forming the 'Jing Mai Lian Huan(經脈連環)' part. The major change in '12 Jing Mai' is that '6 Yang Jing(6陽經)' enters the abdominal and thoracic cavity, directly relating to 'Liu Fu(六腑)'. 'Ben Jing(本經)'s connection to 'Ben Zang' is referred to as 'Shu(屬)' and connection to 'Ben Zang(本臟)' is referred to as 'Lou(絡)', clarifying 'Biao Li Guan Xi(表裏關系)' inside and outslde and 'Zang Fu Xiang He(臟腑相合)' congruency. Looking at the pathological condition view of ‘Jing Mai’, the writer of 'Jing Mai Pian' has renewed it and has erased repeated symptoms of 'Suo Seng Bing(所生病)' that appears in 'Shi Dong Bing(是動病)'. If the wrong adoption of theories of previous generations are corrected and parts which do not comply with the text's original meaning and parts that posterities added are deleted, the ancient acupuncture theory preserved in this book is still a precious treasure.

A 2-year-old spayed female Persian cat presented to Kangwon National University Veterinary Medical Teaching Hospital with pruritus and erythema on the tips of both ears, around the eyes, and in the caudal abdomen. This patient had previously been prescribed prednisolone, but did not respond positively to the treatment. A skin screening test revealed that there were no fleas or fungi, and that only cocci were present. Blood testing revealed no remarkable findings. The patient was prescribed antibiotics (amoxicillin-clavulanic acid 25 mg/kg for 2 weeks) with no prednisolone. After 2 weeks, clinical signs were alleviated and the skin screening test showed no signs of cocci. However, clinical signs recurred even with the prescription of antibiotics. Four weeks after the steroid-free interval, Malassezia spp. hypersensitivity was detected upon a serum allergy test, and pathological analysis confirmed eosinophilic and mastocytic superficial dermatitis in the caudal abdomen. Based on these results, we suspected allergic dermatitis and prescribed 7 mg/kg cyclosporine A once a day. After 3 weeks, clinical signs were resolved. Seven weeks after the first trial with cyclosporine A, we reduced the cyclosporine A dose to 7 mg/kg every other day. The patient's symptoms have since been well controlled for 6 months. This study suggests that cyclosporine A can be a good choice for treating cats with suspected allergic dermatitis that has not responded positively to steroid treatment.

DNA methylation은 무수히 많이 발생하는 생리적 및 병리적 측면의 과정에서 관련 유전자의 발현을 조절함으로써 중추적인 역할을 가지고 있다. 본 연구에서는 NtROS2a가 과발현된 형질전환 벼를 육성하고, 그들의 형태적 측면을 관찰하고 스트레스 내성을 검토하였다. 형질전환 식물체는 WT에 비하여 신초의 신장이 작게 나타났다. 저온 스트레스 처리 하에서 NtROS2a 형질전환 벼는 스트레스로 인한 생육 불량을 보였으나 건조 스트레스 처리 하에서는 WT보다는 높은 비율로 회복하여 생존하는 것을 확인할 수 있었다. 이러한 결과는 NtROS2a 유전자의 과발현으로 인해 벼가 건조 스트레스에 노출되면 내성을 증진시킨 것으로 생각된다.

Two isolates of Cucumber mosaic virus (CMV) originated from lily plants, named Ly2-CMV and Ly8-CMV, were compared with their pathological features in several host plants. Ly2-CMV and Ly8-CMV could induce systemic mosaic symptom in Nicotiana benthamiana, but Ly2-CMV could not systemically infect tomato and cucumber plants that have been used for CMV-propagative hosts. While Fny-CMV used as a control infected systemically the same host plants, producing typical CMV symptoms. Ly8-CMV could infect systemically two species of tobacco (N. tabacum cv. Xanthi-nc and N. glutinosa) and zucchini squash (Curcubita pepo), but Ly2 failed systemic infection on these plants. As resulted from tissue-print immunoblot assay, different kinetics of systemic movement between Ly2-CMV and Ly8-CMV were crucial for systemic infection in tobacco (cv. Xanthi-nc). Sequence analysis of full-length genome of two lily isolates showed Ly2 and Ly8 belonged to subgroup IA of CMV. The lily isolates shared overall 98 % sequence identity in their genomes. Coat protein, 3a protein, and 2b protein involved in virus movement was highly conserved in genomes of the isolates Ly2 and Ly8. Although there is the low frequency of recombinants and reassortants in natural CMV population, phylogenetic analysis of each viral protein among a number of CMV isolates suggested that genetic variation in a defined population of CMV lily isolates was stochastically produced.

Progressive supranuclear palsy (PSP) is a parkinson-plus syndrome characterized clinically by supranuclear ephthalmoplegia, pseudobulbar palsy, axial rigidity, bradykinesia, postural instability and dementia. Presence of dementia and lack of cortical histopathology suggest the derangement of cortical function by pathological changes in subcortical structures in PSP, which is supported by the pattern of behavioral changes and measurement of brain metabolism using positron emission tomography. This study was done to examine whether there are specific changes of regional cerebral perfusion in PSP and whether there is a correlation between severity of motor abnormality and degree of changes in cerebral perfusion. We measured regional cerebral perfusion indices in 5 cortical and 2 subcortical areas in 6 patients with a clinical diagnosis of PSP and 6 healthy age and sex matched controls using $^{99m}Tc$-HMPAO SPECT. Compared with age and sex matched controls, only superior frontal regional perfusion index was significantly decreased in PSP (p<0.05). There was no correlation between the severity of the motor abnormality and any of the regional cerebral perfusion indices (p>0.05). We affirm the previous reports that perfusion in superior frontal cortex is decreased in PSP. Based on our results that there was no correlation between severity of motor abnormality and cerebral perfusion in the superior frontal cortex, nonmotoric symptoms including dementia needs to be looked at whether there is a correlation with the perfusion abnormality in superior frontal cortex.

Objectives : This experiment was designed to assess the single oral toxicity of Ethanol Extract Inulae Flos (IF) ethanol extracts. IF is one of the important herbs to remove phlegmy which is the viscous turbid pathological product that can accumulate in the body, causing a variety of diseases. Nevertheless, there has been a lack of research on the pharmacology toxicity of IF. Methods : In this study, IF was orally administered to 5 weeks ICR mice as an oral dose of 2,000 or 3,000 or 5,000 mg/kg. The condition of the mice was observed for 14 days and their weights were measured every two days. Results : None of the mice died for 14 days. The abnormal clinical symptoms and anatomical signs of toxicity were not found in any treatment groups. The gain of net body weight was observed. There was also no significant difference in the organ weight. The serum biochemistry and hematological analysis showed a decrease in BUN, red blood cells, white blood cells and platelets although within the normal ranges. Conclusions : These results suggest that the 50% lethal dose of IF is more than 5,000 mg/kg. This could be thought that IF is a safe drug without acute toxicity and side effects. However, IF showed some weight loss and change in blood test, so it will need to be careful when using it for high doses.

We came to the conculsion after considering all of information from many kinds of books on the cause, pathogenesis and treatment of Flaccidity-syndrome. The results were as follows : 1. Flaccidity-syndrome means limb-relaxation due to muscle atony that isn't able to constraction. It's begun as mild degree from extremities, in some cases ended to quadriplegia or expire. 2. Cause factor and pathogenesis of Flaccidity-syndrome is various. After Lung fluid consuption caused by heat-evil was refered in The Yellow Emperor's Canon of Internal Medicine. They were refered as cause factor that Main channel asthenia, excess of sexual intercourse, wetness-evil, heat-evil gets into the interior, asthenia of the spleen and stomach. Since Ming Dynasty, It's classified to wetness-heat evil, wetness-phlegm, deficiency of vital energy, deficiency of blood, deficiency of yin, blood stasis and indygestion, etc. 3. In the view of treatment of Flaccidity-syndrome, Yangming was selected in The Yellow Emperor's Canon of Internal Medicine, and it's been mean to clear away wetness-heat evil located at Yangming. In the method of acupuncture it was same on the base, and many skills have been used that electronic acupuncture, point-injection theraphy, acupuncture point block, catgut implantaion at acupuncture point, cutaneous acupuncture, auriculo-acupuncture and head acupuncture by the through post generation. 4. Flaccidity-syndrome was defined to weak, disuse and non-pain. Beacause it was non-pain, so medicine to expel wind-evil was prevented to use. But through post generation Flaccidity-syndrome has been treated that is able to cause pain or numness as arthralgia-syndrome. Therefore there is tendency that medicine to expel wind-evil is capable within pathological basement of Flaccidity-syndrome in recent. 5. In the view of west-medicine, Flaccidity-syndrome is diplegia or quadriplegia with sensory disorder, muscle atropy in some cases. And there are spinal disease, peripheral nerve disease, muscular disease, nerve-muscle copula disease. The symptoms are able to amyotomia, numness, sensory disorder, pain.

The disease occurred in cultured eel (Anguilla japonica) in a recirculatory culture system without any separated filtration apparatus. As the pond had a high level of nitrite with $60mg/{\ell}$, 1% NaCl was added to reduce nitrite toxicity to eel. The first outbreak was observed a week after the NaCl treatment and continued for 10 days. Accumulated mortality was about 0.2-0.5%. Affected fish ranged from 150-350 g were usually anorexic and exhibited yellow colour in the skin of the abdominal region and at the base of pectoral fins, as well as in the eyes. In a few individuals with severe symptoms, the lateral skin was also yellowish. The spleen, kidney, muscle and gall bladder were yellowish and the liver was pale-yellow colour but green on the posterior part. The gall bladder was shrunken without bile. Some abnormal erythrocytes such as "tear drop" cells (dacrocyte) were observed in peripheral blood smears stained with May-Grunwald Giemsa. Hematocrit values and hemoglobin contents in the jaundiced eel were significantly lower compared with apparently heathy eel. Severe haemosiderosis accompanied by erythrophagocytosis was found in the kidney and spleen. Haemosiderin deposits were observed in macrophages of the haematopoietic tissue of the kidney and in the splenocytes. But no significant alterations were found in the hepatic cells. In this study we report the first outbreak of jaundice in cultured eel in Korea. Pathological and hematological investigations suggested that severe hemolysis may resulted in jaundice in eel although the cause of hemolytic jaundice was not identified in this study.
