  • Various kinds of leaf spots and blights were found in kiwifruit (Actinidia deliciosa) orchards on 2006 in Korea. Disease incidences were quite variable between open-field and rain-proof shelter. Rate of diseased leaves was recorded as about 70% at open-field orchards in late season but use of rain-proof vinyl shelters alleviated the disease incidences by 20%. Angular leaf spots appeared at early infection stage on June and several other symptoms were also recognized as the disease developed afterward. On September, brown leaf blights were the most frequent, followed by grayish brown ring spots, silvering gray leaf blights, zonate leaf blights, dark brown ring spots and angular leaf spots at open-field orchards. Four fungal species were frequently isolated from the disease symptoms. Phomopsis sp. was the most predominant fungus associated with the leaf spot and blight symptoms on kiwifruit, followed by Glomerella cingulata, Alternaria alternata and Pestalo-tiopsis sp. Phomopsis sp. was commonly isolated from angular leaf spots, silvering gray leaf blights, and zonate brown leaf blights. G. cingulata, A. alternata and Pestalotiopsis sp. were isolated from grayish brown ring spots (anthracnose), brown ring spots and zonate dark brown leaf blights. Typical symptoms appeared on the wounded and unwounded leaves, which were inoculated by each of Phomopsis sp., G. cingulata, and Pestalotiopsis sp., but A. alternata caused symptoms only on the wounded leaves.

  • In this study, white spots appearing in carapace of imported white leg shrimp Litopenaeus vannamei were observed by macroscopic and microscopic examination. White spots due to white spot disease showed two types, white spots with a regular circular shape ranging from 0.4 mm to 1.7 mm and white spots with an irregular shape ranging from 0.05 mm to 2 mm. White spots due to other causes showed four types that appeared as crystalized materials in range of 100 ㎛ around the tegumental gland, as polygonal inorganic deposits ranging from 58 ㎛ to 188 ㎛, as Linear inorganic deposits ranging from 0.8 mm to 9 mm, as brownish spots ranging from 0.1 mm to 0.4 mm, and brownish spots containing melanin ranging from 0.1 mm to 2 mm. As a result, white spots occurred in imported white leg shrimp Litopenaeus vannamei were divide two type, due to white spot disease or other causes, for quarantine works.

  • Patients with kidney disease require frequent blood tests to monitor their kidney function, which is particularly difficult for young children and the elderly. For these people, the standard method is to evaluate serum creatinine or cystatin C or drug levels through venous sampling, but more recently, evaluation using dried blood spots has been used. This narrative review reports information from the literature on the use of dried blood spots to quantify the main markers used to detect kidney diseases. The ScienceDirect and PubMed databases were searched using the keywords: "dried blood on filter paper," "markers of renal function," "renal function," "creatinine," "cystatin C," "urea," "iohexol," and "iotalamate." Studies using animal samples were excluded, and only relevant articles in English or Spanish were considered. Creatinine was the most assessed biomarker in studies using dried blood spots to monitor kidney function, showing good performance in samples whose hematocrit levels were within normal reference values. According to the included studies, dried blood spots are a practical monitoring alternative for kidney disease. Validation parameters, such as sample and card type, volume, storage, internal patterns, and the effects of hematocrit are crucial to improving the reliability of these results.

  • Alternaria black spots or blights in cruciferous crops have been devastating diseases worldwide and led to economic losses in broccoli, Chinese cabbage, kale, radish, rapeseed, etc. These diseases are caused by different Alternaria spp., including A. brassicae, A. brassicicola and A. raphani transmitted from infected seeds or insect vectors. Efforts to excavate disease resistance traits of cruciferous crops against Alternaria black spots or blights have been demonstrated. Genetic resource of disease resistance was investigated in the wild relatives of cruciferous crops, and different cultivars were screened under different inoculation conditions. Development of the disease-resistant lines against Alternaria black spots or blights was also tried via genetic transformation of the cruciferous crops using diverse plant defence-associated genes. Plant immunity activated by pre-treatment with chemicals, i. e. β-amino-n-butyric acid and melatonin, was suggested for reducing Alternaria black spots or blights in cruciferous crops. The disease resistance traits have also been evaluated in model plant Arabidopsis originating from different habitats. Various plant immunity-related mutants showing different disease responses from wild-type Arabidopsis provided valuable information for managing Alternaria black spots or blights in cruciferous crops. In particular, redox regulation and antioxidant responses altered in the Alternaria-infected mutants were discussed in this review.

  • Therapeutic garments are an undeveloped area and yet they have the potential to generate considerable profit for the fashion industry. In traditional Chinese medicine, there are spots and pathways on the body through which energy flows and practitioners consider that disease results when this energy flow is hindered. Clothes which stimulate the spots can therefore potentially help to cure disease. In addition, clothes are worn every day and can therefore offer prolonged treatment certainly in comparison with other treatments. Obesity is a big problem nowadays and one which is caused by poor energy circulation (according to TCM). A garment which stimulates the spots can assist energy flow and therefore cause the wearer to lose weight. In the process, it can also alleviate side effects of obesity such as diabetes and high blood pressure. The was to stimulate spots include acupuncture, acupressure, moxibustion etc. There are lots of products to press spots which improve energy flow both in the Western and Chinese markets. The basic principle of circulation is in fact the same in both Western and Chinese medicine. However, most of these are products are footwear ones because they can easily provide the necessary stimulation to reduce tiredness and improve circulation. For garments, to press the spots effectively it is best to use tight clothes such as corsets and leggings. The important point is to tighten the body and to make energy flow and yet feel comfortable at the same time. Choice of fabric is therefore an important issue. Although the idea has been introduced, it will be necessary to develop a technique which will allow the necessary amount of pressure to be applied. It could be concluded that this area has a lot of possibility for the future but further research will need to be done before the idea becomes workable.

  • Von Recklinghausen's disease is an autosomal dominant hereditary disease associated with characteristic cafe-au-lait spots of skin and multiple neurofibromatosis. It is complicated by malignancies, which in most cases is neurofibrosarcoma. The development of lung cancer in von Recklinghausen's disease is rare. A 61-year-old male was admitted for cough and sputum for 20 days. He had multiple cafe-au-lait spots and subcutaneous neurofibromas in whole body area and Lisch nodules in both iris and he had been diagnosed von Recklinghausen's disease 35 years ago. Chest radiography showed emphysematous bullae in both upper lung field and mass in right upper lung field. Chest CT scan revealed subcarinal lymph node enlargement. Bronchoscopic biopsy was done in mass in superior segment of right lower lobe and the results showed squamous cell carcinoma. The presence of von Recklinghausen's disease and lung cancer are noteworthy.

  • Leaf spot and blight disease was observed on two-year-old seedlings of Dendropanax morbifera (Korean name: Hwangchil tree) during July of 2008 in Jindo Island, Korea. Symptoms included yellow-brown to dark brown irregularly enlarged spots frequently located along the veins of leaves. The lesions were often surrounded by chlorotic haloes. Severe leaf blight and subsequent defoliation occurred when conditions favored disease outbreak. The causal organism of the disease was identified as Alternaria panax based on morphological characteristics and sequence analysis of the internal transcribed spacer region of rDNA. A. panax isolates induced leaf spots and blight symptoms not only on D. morbifera but also on the other members of Araliaceae tested. This is the first report of foliar blight caused by A. panax on D. morbifera.

  • Von Recklinghausen`s neurofibromatosis, tuberous sclerosis and encephalotrigeminal angiomatosis[Sturge-Kalischer-Weber syndrome] are frequently classified under the heading of organic neurocutaneous syndromes. Both neurofibromatosis and tuberous sclerosis are believed to represent instances of simple autosomal dominant heredity. Multiple neurofibroma and cafe*-au-lait spots are the hallmarks of the van-Recklinghausen`s disease. The characteristic features of the fully developed syndrome are [1] pigmentation of the skin, including cafe*-au-lait spots, pigmented freckles and males, and occasionally a generalized darkening of the skin; [2] subcutaneous nodules and deep neurofibromatous tumors and diffuse plexiform growths of neural tissue; [3] skeletal anomalies, especially scoliosis; and [4] predilection to malignancy. In recent years cystic lung disease, usually of the so-called honeycomb lung variety, has been reported on several occasions in patients with tuberous sclerosis. This association has been shown to our sporadically as well as in members of a single family. Little attention has been paid to the presence of cystic lung disease in association with neurofibromatosis. Currently, most think of thoracic involvement in neurofibromatosis in terms of posterior mediastinal neuroma, pheochromocytoma, meningocele or, less commonly, parenchymal pulmonary neurofibromatosis. Author have experienced a case of von Recklinghausen`s disease. This case developed a huge neurofibroma in the both side thorax and invaded to the Lt. 7th rib.

  • Scab disease of Aralia elata (Miq.) Seemann occurred severely in Kangwon province, Korea. First, brown spots were formed on leaves and enlarged along vein. The infected leaves including petiole and midrib were twisted forming scab and died eventually. Also the disease infected twigs and trunks of the tree forming scab. Conidia, ascospores and asci developed in locule were observed in the infected tissue. The causal organism of the scab disease of Araliae elata was isolated and identified as Elsinoe araliae Yamamoto (imperfect stage: Sphaceloma araliae Jenkins) based on the morphological and cultural characteristics, and pathogenic test.
