Beetle samples were compared between catches by traps and those on flowers in a Japanese beech (Fagus crenata Blume) forest, in Minakami, Gunma Prefecture, Japan. White plastic traps (Sankei Chemical Co., Ltd.) equipped with benzyl acetate were set out for a month from July 23 to August 23, 1993, and all beetles captured were collected every six days. During six days from August 10 to August 16, beetles were captured with traps and on wild flowers (Aruncus sylvester Kostel andAngelica polyclada Franch) at three hour intervals. Over the month, the traps captured 1,677 individuals of 73 species of 20 families, which included 16 (89%) species captured on flowers in the six-day period. Over the six days, the traps captured 327 individuals of 21 species of 12 families, compared with 685 individuals of 18 species of 5 families on the flowers; all of the families and nine (50%) species of beetles taken on the flowers were also captured by the traps; all of the species with more than five individuals captured on the flowers were also trapped. This suggests that capture by traps might sufficiently cover the beetle fauna on flowers. The number of species and individuals, as well as their changing patterns, however, varied more irregularly during the six-day period with the traps than with those on the flowers. A part of this paper were presented at the 46th meeting of the Kanto Branch of the Japanese Forestry Society (1994) These English titles are tentative translation by the authors from the originals  相似文献

Inflammasomes play a pivotal role in gastrointestinal homeostasis and inflammation. However, it remains elusive whether the nucleotide-binding oligomerization domain-like receptor (NLR) family inflammasomes, such as NLR family pyrin domain-containing (NLRP) 3, NLRP6, and NLRP12, are involved in the pathogenesis of canine chronic enteropathy (CE), which includes antibiotic-responsive enteropathy (ARE), food-responsive enteropathy (FRE), immunosuppressant-responsive enteropathy (IRE), and non-responsive enteropathy (NRE). Thus, we measured mRNA expression of NLRP3, NLRP6, and NLRP12 in the intestinal mucosa of 35 dogs with CE (ARE, four dogs; FRE, 11 dogs; IRE and NRE, 20 dogs) and seven healthy dogs. As per real-time PCR analysis, significant increases in mRNA expression of NLRP3 and NLRP12 were noted in the colonic but not in the duodenal mucosa of dogs with FRE compared to healthy dogs. These findings suggested that the NLRP3 and NLRP12 inflammasomes might contribute to the development of colitis in dogs with FRE.  相似文献   

Amputation for histiocytic sarcoma in a cat

A 9-year-old spayed female domestic shorthair cat presented with a skin lesion of the left tarsus. The lesion was biopsied and, based on the microscopic appearance and immunohistochemical characteristics, histiocytic sarcoma was diagnosed. Amputation was performed with improved demeanor seen postoperatively. However, between 44 and 60 days following the surgery, relapse of skin lesions appeared in multiple locations, including at the previous amputation site, and euthanasia was elected. This is the first report of a histiocytic sarcoma treated with amputation in a cat.  相似文献   

Occurrence of ateliosis in Japanese Black calves and their secretory function of growth hormone     

Oguro M  Kawamura S  Takayama M  Ishikawa H  Miura T  Otsuka H  Hoshi F 《The Journal of veterinary medical science / the Japanese Society of Veterinary Science》2003,65(9):1037-1039

Unthrifty calves occurred sporadically in Japanese Black (beef cattle) in an area in northeastern Japan. The states of unthrifty development, pedigree, clinico-biochemistry and the secretory function of bovine growth hormone (bGH) in pituitary were investigated. The total cholesterol concentration and CK, AST and LDH activities in the serum showed higher values than those of control calves. Basal bGH concentrations in the serum and bGH secretory reactivity in the insulin tolerance test (ITT) were showed to be significantly lower than those of the control calves. Furthermore, sperm donated from a specific bull had been used for these unthrifty calves. This study suggested that the present occurrence of unthrifty calves represented ateliosis possibly caused by congenital hypopituitarism which decreased of bGH secretory function.  相似文献

Koji Tanina  Motoaki Tojo  Hirotaka Date  Hideo Nasu  Shinji Kasuyama 《Journal of General Plant Pathology》2004,70(3):188-191

Severe rot was found at the base of leaves and stems of chingensai (Brassica campestris L. chinensis group) in Okayama Prefecture in 2000. The causal fungi were morphologically identified as Pythium ultimum Trow var. ultimum and P. aphanidermatum (Edson) Fitzpatrick. This is the first report of rot caused by Pythium species on chingensai. We named this disease Pythium rot of chingensai.  相似文献   

β-1,3-D-Glucan Transported from Golgi Apparatus of Japanese Pear Leaves is a Component of Extracellular Polysaccharides Accumulated after AK-toxin I Treatment     

Tomoko SUZUKI  Takeshi SHINOGI  Kazutoshi UNNO  Yoshihiro NARUSAKA  Pyoyun PARK 《Journal of General Plant Pathology》2002,68(4):267-276

This fluorescence and immunoelectron microscopic study showed that β-1,3-D-glucan accumulated only in leaves of a susceptible cultivar of Japanese pear after treatment with a host-specific toxin, AK-toxin I, from Alternate, alternata Japanese pear pathotype. The positive fluorescent reaction of callose was detected only in aniline blue fluorochrome-stained sections from toxin-treated leaves of the susceptible cultivar: positive sites were observed on cell walls of leaf cells. The sites of callose deposition were probably consistent spatially with modified sites on the plasma membrane that were observed only in the toxin-treated leaves of the susceptible cultivar. The toxin-induced modifications, identified as damage to the plasma membrane, were characterized by invagination of the plasmalemma specifically at plasmodesmata and as the concomitant accumulation of extracellular polysaccharides at the invaginated sites. A positive reaction to anti-β-1,3-D-glucan antibody was detected at the polysaccharides, Golgi vesicles, and trans-Golgi network (TGN) of toxin-treated leaves of the susceptible cultivar, but not at Golgi vesicles and TGN of water-treated ones. The cis-, medial and trans-Golgi stacks of toxin-treated leaves of the susceptible cultivar were negative for the antibody. The results showed that the polysaccharides, Golgi vesicles and TGN contained abundant β-1,3-D-glucan and that the glucan was transported from the Golgi apparatus via Golgi vesicles to the modified sites in cells of toxin-treated leaves of the susceptible cultivar.

Preparation and characterization of fermented seaweed sauce manufactured from low-quality nori (dried and fresh fronds of <Emphasis Type="Italic">Pyropia yezoensis</Emphasis>)     

Motoharu Uchida  Hirotaka Kurushima  Nobuo Hideshima  Toshiyoshi Araki  Kenji Ishihara  Yuko Murata  Ken Touhata  Noriko Ishida 《Fisheries Science》2018,84(3):589-596

The present study tested processes to manufacture fermented sauce from low-quality nori (dried and fresh fronds of Pyropia yezoensis). The nori sauce was prepared using three tanks with fresh or dried nori cultured in different conditions. In the present study enzymes were not added for the promotion of the degradation of nori, while in a previous study they were. The supernatants of culture mashes obtained from the three tanks were combined, and this low-quality nori sauce (LNS) was characterized and compared with sauces manufactured from high-quality nori, soy, and fish. The LNS showed low concentrations of total nitrogen compounds (0.20 g/100 ml) and free amino acids, and its taste showed a high sourness score as evaluated by a taste-sensing system. On the other hand, the LNS was rich in polysaccharides, which were observed to be readily degraded to lower molecular weight size sugars by heat treatment. The LNS showed little risk for heavy metal or allergen contamination. The obtained sauce product is expected to be commercially utilized as a component of low allergen-risk sauce products after blending with other seasonings without wheat or soy elements.  相似文献   

Highly efficient induction of triploid Pacific abalone <Emphasis Type="Italic">Haliotis discus hannai</Emphasis> by caffeine treatment

ABSTRACT:   In order to develop a highly efficient method for mass production of triploid Pacific abalone Haliotis discus hannai , caffeine treatment that is safe and inexpensive was optimized. To suppress the first meiotic division, fertilized eggs were exposed to either a 10- or 15-mM caffeine solution for 24 min beginning at 12 min after fertilization. In most treated batches, the rates of cleaved eggs showed no significant difference from the control batches. However, in most treated batches, the rates of occurrence of normal larvae and the survival rates of the early juveniles were significantly lower than those of the controls. The triploid rates at 6 days to 11 months after settlement in all the treated batches were extremely high (91–100%). There was no significant difference in the mean triploid rates between 10- and 15-mM caffeine treatments. These results suggest that both treatment conditions were conducive to triploid abalone production. One live 2n/3n mosaic specimen was found in the treated batches. However, since the frequency of mosaic was extremely low, the mosaicism would probably not have an adverse effect on the stable production of triploid abalones.  相似文献   

Clinical,histopathological, and immunohistochemical studies of histiocytic sarcoma in four-toed hedgehogs (Atelerix albiventris): A retrospective study     

Risa MAKISHIMA  Hirotaka KONDO  Hisashi SHIBUYA 《The Journal of veterinary medical science / the Japanese Society of Veterinary Science》2021,83(3):419

Histiocytic sarcoma was investigated histopathologically and immunohistochemically in 17 four-toed hedgehogs (Atelerix albiventris), along with a review of their clinical data. Cases were histopathologically classified into two types: round-polygonal cell type (6 cases) and spindle cell type (11 cases). Round-polygonal cell type was found in visceral organs such as the spleen, lymph nodes, and more, and most cases of this type were consistent with disseminated histiocytic sarcoma. On the other hand, spindle cell type occurred mainly in skin, and almost all cases were consistent with localized histiocytic sarcoma. The prognosis of patients with round-polygonal cell type appeared worse than that of spindle cell type. Immunohistochemically, neoplastic cells of spindle cell type showed stronger reactivity against human leukocyte antigen-DR than round-polygonal cell type. Neoplastic cells of all cases showed strong reactivity against ionized calcium-binding adapter molecule-1 (Iba-1) and various reactivities against cluster of differentiation (CD) 204. Regardless of morphological classification, most tumor cells were negative for CD163, suggesting that this marker is less effective for the diagnosis of histiocytic sarcoma. The results of this study suggest that Iba-1 is the most effective marker for histiocytic sarcoma.  相似文献
