Kiwifruit (Actinidia spp.) is an economically important crop and a bacterial canker disease, caused by Pseudomonas syringae pv. actinidiae (Psa), is the most destructive disease in kiwifruit production. Therefore, prevent and control of the disease is a critical issue in kiwifruit industry worldwide. Unfortunately, there is no reliable control methods have been developed. Recently, interest in disease control using microbial agents is growing. However, kiwifruit microbiota and their roles in the disease control is mainly remaining unknown. In this study, we secured bacterial libraries from kiwifruit ecospheres (rhizosphere, endospere, and phyllosphere) and screened reliable biocontrol strains against Psa. As the results, Streptomyces racemochromogenes W1SF4, Streptomyces sp. W3SF9 and S. parvulus KPB2 were selected as anti-Psa agents from the libraries. The strains showed forcible antibacterial activity as well as exceptional colonization ability on rhizosphere or phyllosphere of kiwifruit. Genome analyses of the strains suggested that the strains may produce several anti-Psa secondary metabolites. Our results will contribute to develop biocontrol strains against the kiwifruit canker pathogen and the disease management strategies.

Enuresis is intermittent urinary incontinence during sleep at night in children aged 5 years or older. The main pathophysiology of enuresis involves nocturnal polyuria, abnormal sleep arousal, and low functional bladder capacity. In rare cases, enuresis is an early symptom of endocrine disorders such as diabetes or thyroid disorders. Herein, we report a case of a 12-year-old girl with enuresis as a rare initial presentation of Graves' disease. She complained of nocturnal enuresis from a month before visiting our clinic. She also complained of urinary frequency, headache, and weight loss. On physical examination, she had tachycardia, intention tremors, and a diffuse goiter on her anterior neck with bruit on auscultation. Her thyroid function test results revealed hyperthyroidism, and Graves' disease was diagnosed as the thyroid stimulating hormone receptor autoantibody was positive. After treatment for Graves' disease with methimazole, symptoms of enuresis resolved within 2 weeks as she became clinically and biochemically euthyroid. In children with secondary enuresis, Graves' disease should be considered as a differential diagnosis, and signs of hyperthyroidism should be checked for carefully.

지역사회 뇌졸중환자들의 치료 지속률과 약물 순응도에 대한 연구는 아직 많이 실시되지 않았다. 그러나 치료 지속률과 약물 순응도가 뇌졸중의 재발 및 사망과 밀접한 관련이 있다는 것은 많이 알려진 사실이다. 이에 본 연구는 지역에 거주하고 있는 뇌졸중환자들을 임의 추출하여 이들의 치료 지속률과 약물 순응도를 평가하고 이에 영향을 미치는 요인을 찾기 위하여 실시되었다. 연구대상자는 429명으로 이들의 뇌졸중 치료율과 현재 복용하고 있는 약물의 순응률을 파악하였으며 약물 순응도는 의도적 비순응군과 비의도적 비순응군으로 구분하여 조사하였다. 연구 결과 치료 지속률은 86.5%였으며 이들 중 약물 순응도는 41.2%였다. 치료 지속률에 영향을 미치는 요인으로는 보건교육 경험뿐이었으며, 비의도적 약물 비순응에 영향을 미치는 요인은 mRS와 보건교육 경험 그리고 의도적 약물 비순응에 영향을 미치는 요인은 mRS와 우울감 정도 그리고 약물에 대한 신념(필요성, 염려)이었다. 결론적으로 지역사회 뇌졸중환자의 재발방지와 사망률감소를 위하여 약물복용을 중요하게 교육하여야 할 것이며 순응도 향상을 위해서는 약물에 대한 필요성은 올리고 염려 수준을 낮추도록 교육하여야 할 것이다.

Over the past decade, clubroot has emerged as a major constraint to canola (Brassica napus) production in central Alberta, Canada. The number of fields with confirmed P. brassicae infestations in Alberta has increased steadily from 12 in 2003 to nearly 2,000 in 2014. Management of clubroot on canola has focused on sanitization of field equipment, soil amendments to reduce viable pathogen populations, long rotations out of susceptible crops and cropping of resistant cultivars. Clubroot resistance is the most effective and economical method of disease mitigation, but the recent identification of isolated P. brassicae populations with novel virulence phenotypes capable of overcoming resistance in most canola cultivars highlights the variable nature and adaptability of the pathogen. Recent studies have shown slight reductions in pathogen populations through crop rotations, but much more substantial reductions in spore populations in heavily infested areas near field entrances using fumigants such as Vapam (metam-sodium) or Basamid (dazomet). Greenhouse trials showed that seedling emergence, plant height and root weight increased, while primary and secondary infection and disease severity decreased with increased Basamid dosage. However, field trials showed some phytotoxicity. Application of Vapam at rates of 0.4 to $1.6mL\;L^{-1}$ soil resulted in 12-16 fold reductions in clubroot severity and primary and secondary infection. Vapam also was effective in reducing clubroot severity and improving canola seed yield under field conditions. These studies underscore the need for good resistance stewardship and for the integration of multiple products and practices for successful management of clubroot on canola.

The oral lesion of acquired syphilis - primary, secondary, and tertiary - is comparatively rare. Most of the time secondary syphilis manifests itself as a systemic disease with maculopapular eruptions of the skin, generalized lymphadenopathy, fever, and occasional eruptions on the mucous membranes. The lesions of the tertiary stage may occur anywhere in the body, including the oral cavity. Necrotizing faciitis of the head and neck is an uncommon, rapidly spreading soft tissue infection of polymicrobial origin characterized by extensive necrosis and gas formation in the subcutaneous tissue and superficial fascia. This is characterized by its fulminating, devastating, and rapid-progressing course. The mortality rate is high if it is not treated promptly and vigorously. Patients with an impaired immune system and those with small-vessel disease such as diabetes mellitus are more prone to develop this infection.

Beau first described transverse depressions of the fingernails after an acute febrile illness in 1846. It was the result of the temporary arrest of nail matrix formation. The transient interference of nail growth rate is usually induced by disability caused by severe systemic disease. Such as Raynaud disease, myocardial infarction, pulmonary embolism, acute renal failure, psoriasis and dysmenorrhea were reported to be the cause of Beau's line. The trauma caused either in a hand or in a forearm was also reported to be the cause of Beau's line. We experienced patients with Beau's line, two cases secondary to fingertip injury and one case due to fracture in radius. They had Beau's lines in all fingers of traumatized hand and nails of opposite hand were normal. During the follow-up, the growth rate of traumatized fingernails were normal and there was no complication.

Malaria is an infectious disease affecting humans, which is transmitted by the bite of Anopheles mosquitoes harboring sporozoites of parasitic protozoans belonging to the genus Plasmodium. Despite past achievements to control the protozoan disease, malaria still remains a significant health threat up to now. In this study, we cloned and characterized the full-unit Plasmodium yoelii genes encoding merozoite surface protein 1 (MSP1), circumsporozoite protein (CSP), and Duffy-binding protein (DBP), each of which can be applied for investigations to obtain potent protective vaccines in the rodent malaria model, due to their specific expression patterns during the parasite life cycle. Recombinant fragments corresponding to the middle and C-terminal regions of PyMSP1 and PyCSP, respectively, displayed strong reactivity against P. yoelii-infected mice sera. Specific native antigens invoking strong humoral immune response during the primary and secondary infections of P. yoelii were also abundantly detected in experimental ICR mice. The low or negligible parasitemia observed in the secondary infected mice was likely to result from the neutralizing action of the protective antibodies. Identification of these antigenic proteins might provide the necessary information and means to characterize additional vaccine candidate antigens, selected solely on their ability to produce the protective antibodies.

Through a literal study upon the cause of epilepsy between east and west medicine, next conclusion have been abtained. 1. The cause epilepsy in the east medicine, congenital embryo disease is due to insufficiency of heart(心虛) or deficiency of heart energy(心氣虛), secondary cause is wind -evil(風), frightness(驚), phlegm(痰), fire(火) 2. The cause epilepsy in the west medicine is divided congenital disease and secondary cause, one is excessive discharge of electricity of the brain have on a central nerve, a digestive organ, a respiratory organ, hamatogenous functions, the other is hereditary it and pathological it. 3. The epilepsy is concerned about the abnormality in five viscera, liver, spleen, heart. 4. In comparison east and west medicine of epilepsy is native factor, or innate primary cause is added to outer cause of wind-evil(風), cold-evil(寒), summer-heat(署), wetness(濕), and inner cause of frightness-terror(驚-恐), seven modes of emotions(七情) and the epilepsy is occurred phlegm(痰), fire(火). It similar that the epilepsy is occurred to structural and functional obstacle in western hereditary and primary cause.

Objective : The results of secondary transsphenoidal surgery(TSS) for either residual or recurring pituitary adenomas have been reported to be unfavorable. To evaluate the effectiveness of secondary TSS, we analyzed the surgical results of residual or recurred pituitary adenomas in patients who underwent secondary TSS from 1992 to 1998. Material and Methods : Among the 95 patients who underwent TSS during this period, 14(15%) received repeated TSS. Two of the 14 patients underwent three TSS. Among the 11 patients with pituitary adenomas, three had nonfunctioning tumors ; six prolachnomas ; two GH-secreting adenomas. The remaining three patieats had craniopharyngioma, pituitary abscess and hemangioendothelioma respectively. The interval between the two surgical procedures ranged from one week to 33 months(mean ; 12 months). Causes of the secondary TSS were tumor recurrence in 11 patients, intentional staged operation in three, persistent disease despite medical therapy and CSF leak after initial operation in one respectively. Treatments prior to secondary TSS were medical treatment only in eight patients. Results : During the repeated operationtss some adhesion was noted in septal mucous membrane. The sphenoid cavity was filled with fibrous tissue which correlated with the methods of reconstruction of the sellar floor at the previous operation. There was no statistically significant difference in success rate of surgery between the initial and the second TSS(86% vs 81%). The complication rate was similar between the two procedures. There was no statistically significant factors affecting the results of second TSS. Conclusion : Transsphenoidal reoperation was regarded as a suitable approach for treating recurrent pituitary adenomas in spite of some degree of operative difficulties. In patients with transsphenoidally resectable tumor residuals or recurrences confirmed by magnetic resonance imaging, remissions can be obtained with high probability, especially in secondary surgery after an staged decompression.
