A 7-year-old dog weighing 3.9 kg visited the hospital with symptoms of inability to stand and quadriparesis. There were seizure symptoms 2 months before admission to the hospital, and the symptoms of stiffness and rigidity appeared. Radiographs showed normal vertebrae in cervical vertebral column. Magnetic resonance imaging (MRI) and computed tomography (CT) were performed immediately to diagnose vertebral lameness. As a result of the CT, it was possible to observe the fracture of the odontoid process of the axis, and the exact location of the damage was identified. The odontoid process was fractured and separated from the body of the 2^nd cervical vertebra (axis), and fragment of the process was observed inside the vertebral arch of the first cervical vertebra (atlas), and the body of the axis was lifted to the dorsal side. The MRI examination reflected the CT findings and confirmed severe spinal cord compression due to the fracture of the odontoid process. The patient was applied by neck brace and medical management including Mycophenolate mofetil administration was performed. The patient was able to move legs and tail after 2 weeks, and was able to voluntarily defecate, urinate and stand up after 4 weeks of administration.

Background: Hydrogen sulfide is a toxic substance that humans can be exposed to occupationally, and cases of hydrogen sulfide poisoning of workers in industrial sites are commonly reported. However, there have been no cases of poisoning of the public due to an unauthorized discharge of wastewater, so it is important to describe this incident. Case presentation: In a small village in Jeollanam-do, Republic of Korea, accounts of a terrible stench had been reported. A 26-year-old man who lived and worked in a foul-smelling area was taken to the emergency room with a headache, dizziness, nausea, and repeated syncope. A subsequent police and Ministry of Environment investigation determined that the cause of the stench was the unauthorized discharge of 9 tons of wastewater containing hydrogen sulfide through a stormwater pipe while the villagers were sleeping. The patient had no previous medical history or experience of symptoms. Leukocytes and cardiac markers were elevated, an electrocardiogram indicated biatrial enlargement, left ventricular hypertrophy, and corrected QT interval prolongation. Myocardial hypertrophy was detected on a chest computed tomography scan, and hypertrophic cardiomyopathy was confirmed on echocardiography. After hospitalization, cardiac marker concentrations declined, symptoms improved, and the patient was discharged after 7 days of hospitalization. There was no recurrence of symptoms after discharge. Conclusions: We suspect that previously unrecognized heart disease manifested or was aggravated in this patient due to exposure to hydrogen sulfide. Attention should be paid to the possibility of unauthorized discharge of hydrogen sulfide, etc., in occasional local incidents and damage to public health. In the event of such an accident, it is necessary to have government guidelines in place to investigate health impact and follow-up clinical management of exposed residents.

The average annual and winter ambient air temperatures in Korea have risen by $0.7^{\circ}C$ and $1.4^{\circ}C$, respectively, during the last 30 years. Due to climate change, the occurrence of abnormal weather conditions has become more frequent, causing damage to vegetable crops grown in Korea. Hot pepper, chinese cabbage and radish, the three most popular vegetables in Korea, are produced more in the field than in the greenhouse. It has been a trend that the time for field transplanting of seedlings is getting earlier and earlier as the spring temperatures keep rising. Seedlings transplanted too early in the spring take a longer time to resume the normal growth, because they are exposed to suboptimal temperature conditions. This experiment was carried out to figure out the change of cellular tissue of chinese cabbage under the condition of low temperature to provide the information regarding the coming climatic change, on the performance of 'Chunkwang' chinese cabbage during the spring growing season. In our study, plant height, number of leaf, chlorophyll and leaf area was lower at the open field cultivation than heating house treatment after transplanting 50 days. Especially in fresh weight, compared with heating treatment, open field and not heated treatment were notably low with the 1/3 level. Of damage symptoms due to low temperature cabbage leaves about 10 sheets when $-3.0^{\circ}C$ conditions in chinese cabbage was a little bit of water soaking symptoms on the leaves. $-7.4^{\circ}C$ under increasingly severe water soaking symptoms of leaf turns yellow was dry. Microscopy results showed symptoms of $-3.0^{\circ}C$ when the mesophyll cell of palisade tissue and spongy tissue collapse, $-7.4^{\circ}C$ palisade tissue and spongy tissue was completely collapsed. The result of this study suggests that the growers should be cautioned not to transplant their chinese cabbage seedlings too early into the field, and should be re-transplanting or transplanting other plants if chinese cabbage are exposed to suboptimal temperature conditions ($-3.0^{\circ}C$ or $-7.4^{\circ}C$).

Broad bean wilt virus 2 (BBWV2) is a species in the genus Fabavirus and family Secoviridae, which is transmitted by aphids and has a wide host range. The BBWV2 genome is composed of two single-stranded, positive-sense RNAs, RNA-1 and RNA-2. The representative symptoms of BBWV2 are mosaic, mottle, vein clearing, wilt, and stunting on leaves, and these symptoms cause economic damage to various crops. In 2019, Perilla fructescens leaves with mosaic and yellowing symptoms were found in Geumsan, South Korea. Reverse-transcription polymerase chain reaction (RT-PCR) was performed with specific primers for 10 reported viruses, including BBWV2, to identify the causal virus, and the results were positive for BBWV2. To characterize a BBWV2 isolate (BBWV2-GS-PF) from symptomatic P. fructescens, genetic analysis and pathogenicity tests were performed. The complete genomic sequences of RNA-1 and RNA-2 of BBWV2-GS-PF were phylogenetically distant to the previously reported BBWV2 isolates, with relatively low nucleotide sequence similarities of 76-80%. In the pathogenicity test, unlike most BBWV2 isolates with mild mosaic or mosaic symptoms in peppers, the BBWV2-GS-PF isolate showed typical ring spot symptoms. Considering these results, the BBWV2-GS-PF isolate from P. fructescens could be classified as a new strain of BBWV2.

Objectives : This paper aims to examine the meaning of Shengmaisan in relation to original qi based on the discussion of Zhangyuansu, Lidongyuan and other doctors. Methods : Discussion of Shengmaisan made by Zhang, Li and others were examined. Afterwards, the medicinal properties of renshen, maimendong, and wuweizi as written in the Bencaogangmu, Donguibogam, Benjingshuzheng and texts of Zhang and Li were studied in relation to original qi. Related concepts such as '肺中伏火'·'補肺中元氣不足'·'補天眞元氣'·'夏食寒' were analyzed as well. Results & Conclusions : 1. Various pathology related to deficiency in original qi could act as internal pathogen for Shengmaisan application with which external factors such as summerheat and dampness heat meet results in most damage in the Lung metal. Therefore the upper body Lung is emphasized as pathogen. 2. The pathology of Shengmaisan application is depletion of humor, which should be refined, due to summer or dampness heat in a state of original qi deficiency which damages the Lungs, disabling its function of managing clear and pure qi. 3. The disease pattern for Shengmaisan in relation to original qi, according to other doctors, includes symptoms related to the Lungs such as dryness in the mouth due to excessive perspiration, blankness, loss of consciousness, shortness of breath, coughing, fast breathing, along with general bodily symptoms such as heavy sensation of the body, lethargy, difficulty walking, limping. These general bodily symptoms are due to either qi deficiency of the Lung, or humor deficiency due to failure of qi convergence in the lower body, or symptoms caused by Jing deficiency in severe cases. Symptoms related to problems in the lower body could manifest as dysfunction in urination and defecation, weakness in the limbs caused by original qi deficiency. 4. The Lungs circulate the clear and pure qi, converging qi and creating humor to assist the Triple Burner's Qi-Humor metabolism, enabling smooth communication of original qi throughout the body. With the original qi well tonified, the shen mechanism which is rooted in original qi allows for autonomous and consistent qi circulation within the body. Therefore, both Zhang and Li emphasized the importance of original qi. The property of Shengmaisan is explained as 'supplement qi/create liquid, convergence of yin/stop perspiration'. Zhang and Li explained its property as managing the circulation of original qi, to tonify Lungs' original qi and origin of water-humor.

The relations of the growth responses of plants, i.e. 4 species of crops, 12 species of roadside trees and 5 species of horticultural plants to cadmium (Cd) to which added soil were studied in pot culture. Growth in dry weight of corn, soybean, barley and wheat plant were decreased with increase of Cd concentration. Damage of corn plant caused by Cd treatment was more or less recovered when it was grown in soil with calcium, but that of other three crops was not recovered when it was with calcium. Although crop plants used here absorbed small amount of Cd through root, Cd content in the shoot was directly proportionate to the concentration of Cd treated to soil. Additions of calcium and sulfur to soil were effectively to change of soil pH, and only of calcium increased exchangeable calcium and cation exchange capacity of its soil. The chlorosis on leaves caused by Cd treatment was observed in 2 species such as Euonymus japonica and Rhododendron yedoense out of 5 species of the horticultural plants, especially at 50ppm of Cd concentration, Euonymus japonica occurred symptoms of chlorosis and difoliation, and at the higher concentration than that the symtoms were sever more and more. At 200 ppm of Cd feeble damage was observed in Pinus koraiensis and Ginkgo biloba but severe chlorosis observed in Robinia pseudoacacia and Sabina chinensis, Buxus koreana, Abies holophylla and Platanus orientalis. Nevertheless those plants had serious damage at 200 ppm of Cd, such symptom was weakened by adding calcium to soil with Cd. There were many Cd tolerant species out of the plants used in thies xperiment, such as Crassula falcata, Chrysanthemum morfolium, Hibiscus syriacus, Ligustrum ovalifolium, Liriodendron tulipeferia, Lespedeza crytobotrys.

We have experienced a case in which herbal medicine was administered to treat drug-induced liver damage and would like to introduce it. A 49-year-old man exhibited a positive result in the interferon-gamma release assay. He had never suffered from tuberculosis in the past, and the route and time of infection could not be confirmed. He had no respiratory or systemic symptoms suggestive of active tuberculosis, and a chest X-ray examination showed no active lung lesions, so he was diagnosed with latent tuberculosis infection. He was confirmed to be within the normal range in the liver function test, renal function test, and complete blood cell count test, and started taking rifampin (600 mg qd). In the screening test performed on the 19th day of taking the drug, other test items were normal, but alanine aminotransferase (ALT) increased to 50 U/L (reference value: 4-40 U/L). In a test performed on the 29th day of taking the drug, ALT was clearly elevated to 102 U/L. Ursodeoxycholic acid and Injinho-tang were taken together with rifampin, and the patient's progress was observed. In a test performed 14 days later, ALT decreased to 26 U/L, within the normal range. It is presumed that Injinho-tang may have partially contributed to alleviating liver damage in this case.

Over 2,000 ha of rice fields in the western and southern coastal region of Korea were flooded with sea water during the spring tide, on August 19-21, 1997, and the rice plant at heading stage was injured. The field surveys were undertaken at the sea water flooded paddy fields in Chonbuk Province, to identify the injury symptoms and rice yield damage subjected to different flooding condition and desalinization methods. Five days after sea water flooding at heading stage, the flag leaves of rice plants flooded with 30 ㎝ deep sea water withered from the tip, the withering progressed to the lower leaves in deeper flooding. The spikelets were spotted black and discolored from the tip at 50 ㎝ deep flooded rice, and some panicles changed to white at 80 ㎝ deep flooded rice. Most of the rice leaves submerged completely for an hour were withered and most of panicles changed to white. The milled rice yield, percentage of ripened grain, and 1000 grain weight of flooded rice decreased with deeper flooding water, higher water salinity and longer flooding time. Even under the same flooding conditions, the damage of rice yield varied with the growth stage: heading stage>dough stage>booting stage. Rice yield damage was less in the fields on the upper riverside than those of the fields on the estuary and seaside, because of lower water salinity. In a flooded field, the rice yield damages were reduced as the distance increased from the levees where the sea water inflowed and increased as the distance increased from the fresh water irrigation gate. The desalinization treatments consisting of frequent exchange of irrigation water and spraying with fresh water soon after flooding effectively reduced the rice yield damage.

This paper is a purpose to Analyze and study the failure examples for a engine oil leakage of camshaft bearing seal, poor contact by computer connector fin damage and vaporizer inferiority on LPG automotive. The first example, when the researcher disassembled the cylinder head of engine to establish the cause for oil leakage, he confirmed the engine oil leakage by damaged between the engine intake camshaft bearing and seal part. The second example, the connector fin of power source line that control the starting of a car supplied with engine computer. As a result, it found the fact that the engine operation stopped because of cutting of the power source by connector fin damage. The third example, it verified the engine incongruity phe cutting of the power source by connector fin damage. The third example, it verified the engine incongruity phenomenon as thd gas didn't flow the vaporizer by foreign substance deposit. Finally, it supplied a small quantity gas from vaporizer to mix. As the computer controlling mix opening condition supplied a air as opening signal, the air and fuel became rarefied state. it knew that the engine didn't produce prpper power. Therefore, a car have to throughtly inspect not in order to arise the failure symptoms.
