• Introduction
In Cryptomeria japonica, heartwood properties are considered to be affected by specific extractives. It remains unclear whether traits of specific heartwood compounds are under genetic control. 相似文献112.

Helleborus net necrosis virus (HeNNV) in hellebores (Helleborus spp.) has been detected for the first time in Japan. Infected plants had black streaks on fresh leaves and black spots on
sepals, which resembled the symptoms of black death disease. The morphology of the virus particles isolated from infected
plants was comparable to that of carlaviruses. RT-PCR analysis showed that the entire HeNNV genomic sequence isolated in Japan
shared 99% identity with that of HeNNV previously reported in the United States. 相似文献

We herein present clinical findings of an Iriomote cat with Hepatozoon felis parasitemia. A male Iriomote cat was captured for ecological analyses three times from January 2010 to January 2011. Although this cat did not show any hematological abnormalities at the time of the first capture, H. felis parasitemia and increased serum creatine kinase levels were detected at the second and third captures. H. felis infection was confirmed by polymerase chain reaction, and amplified 18S ribosomal RNA gene fragments were 100% identical to those of H. felis in leopard cats in Korea. Although the virulence of H. felis in this cat was suggested to be low, this is the first report of an H. felis-infected Iriomote cat with parasitemia. 相似文献

The Spontaneously Diabetic Torii-Lepr(fa) (SDT- fa/fa) rat is a new model of obese type 2 diabetes. The female SDT-fa/fa rat shows obesity, hyperglycemia and hyperlipidemia from a young age. However, it is not known whether diabetes and estrogen deficiency can lead to bone abnormalities in the female SDT-fa/fa rat. The objective of the present study was to investigate the effects of ovariectomy (OVX) on bone metabolism and bone mineral density (BMD) in the female SDT-fa/fa rat. Female Sprague-Dawley rats were used as control animals. The BMDs of the whole tibia and fifth lumbar (L5) vertebral body were analyzed at 30 weeks after OVX. Serum osteocalcin, a bone formation marker, and urine deoxypyridinoline (DPD), a bone resorption marker, were sequentially analyzed before and at 5, 15 and 30 weeks after OVX. Serum osteocalcin and urine DPD levels were lower in SDT-fa/fa rats than in control rats before OVX. Both serum osteocalcin and urine DPD levels were elevated in control rats 5-30 weeks after OVX, but only the urine DPD levels were elevated in SDT-fa/fa rats 5-30 weeks after OVX. SDT-fa/fa rats showed a decrease in the BMDs of the whole tibia and L5 vertebral body compared with control rats. OVX decreased the BMDs of the whole tibia and L5 vertebral body in control rats, but not in SDT-fa/fa rats. These data suggest that estrogen deficiency is not a risk factor for bone loss in type 2 diabetes mellitus. 相似文献

Cytochrome P450 (CYP) 1B1 is involved in the metabolic activation of various procarcinogens, and some CYP1B1 genetic variants alter CYP1B1-dependent procarcinogen metabolism. Cynomolgus and rhesus macaques are frequently used in toxicity tests due to their evolutionary closeness to humans. In this study, we attempted to identify CYP1B1 genetic variants in 13 cynomolgus and 4 rhesus macaques. A total of 17 genetic variants were identified, including 8 non-synonymous genetic variants, indicating that, similar to humans, CYP1B1 is polymorphic in macaques. These CYP1B1 genetic variants could be the basis for understanding potential inter-animal differences in macaque CYP1B1-dependent metabolism of promutagens. 相似文献

The location of carbonic anhydrase III (CA-III) in frozen sections of biopsies of Thoroughbred horse skeletal muscle was studied. Fibre types were determined by ATP-ase and succinate dehydrogenase staining. CA-III isozyme was detected using a peroxidase conjugated anti-CA-III antibody. CA-III was found to be localised in slow twitch oxidative fibres (ST), but was also present in fast twitch oxidative (FTH) fibres in small amounts. Fast twitch glycolytic (FT) fibres were stained lightly compared with control sections. The concentrations of CA-III in muscle and liver were 70 micrograms/mg protein and 4 micrograms/mg protein, respectively. CA-I and CA-II were not found in muscle extracts by the double immunodiffusion method. 相似文献

In this study, a retrospective analysis was conducted to assess the current aspects and predisposing factors of canine sterile panniculitis. Miniature dachshund, neutered, and younger dogs appeared to be predisposed. In addition, histories of previous surgery and injection were associated in 46.5% of the cases, with several types of surgical suture materials used. About 88% of the dogs had multifocal lesions, frequently with signs of systemic illnesses. Whereas systemic immunosuppressive therapy was effective in most dogs, surgical excision of lesions was rarely curative. In order to prevent recurrences, over 65% of the cases required prolonged immunosuppressive therapy. Polymorphism of canine alpha(1)AT gene was investigated as a candidate gene for sterile panniculitis. Eight polymorphisms were discovered in seven Miniature dachshunds by direct nucleotide sequencing, which included a 12-bp deletion, three non-synonymous single nucleotide polymorphisms, and four silent substitutions. Genotyping of the two polymorphisms, c.109_120del12 and c.483A>C, which identified at high incidence in the dachshunds, was conducted in 83 dogs of 6 popular breeds. The frequencies of neither polymorphism differed between Miniature dachshunds and other breeds, suggesting that neither is responsible for developing panniculitis. 相似文献

Soft feces and a decreased delivery rate were observed in a specific-pathogen-free (SPF) C3H-scid mouse breeding colony. Grossly, the ceca were shrunken and edematous in the affected mice. Histopathologically, severe edema in the cecal submucosa as well as infiltration of inflammatory cells in the lamina propria and submucosa of the ceca and colon were observed. No pathogenic microorganisms were detected by the routine microbiological tests. By anaerobic bacterial-examination, Clostridium (C.) difficile with toxin A was isolated from the cecal contents of the affected mice. The mice were diagnosed with C. difficile-associated colitis. This case appears to be the first report of natural infection with C. difficile in SPF mice with clinical signs. 相似文献

An 11-month-old Japanese Black steer with chronic bloat underwent clinical and histological analyses. During the observation period, it showed normal appetite and fecal volume but persistent chronic bloat symptoms. Compared to controls, the steer's feces contained undigested large straws. Necropsy revealed normal rumen, reticulum, and abomasum but a small omasum. The rumen, reticulum, and abomasum mucosa was normal, with well-developed ruminal papillae. However, severe hypoplasia of the omasal laminae was observed along with hypoplasia reticular groove and ruminoreticular fold. The contents of the reticulum, omasum, and abomasums comprised undigested large sized hay particles. The omasum papillae showed no pathological abnormalities. This is a rare case of a steer with chronic bloat probably caused by severe hypoplasia of the omasal laminae. 相似文献

The performance of horses undergoing regular intense exercise is adversely affected by
oxidative stress. Thus, it is important to increase antioxidant production in horses in
order to reduce oxidative stress. Ozonated autohemotherapy (OAHT) reportedly promotes
antioxidant production. This study aimed to evaluate the effects of OAHT on antioxidant
capacity. Ten Thoroughbred horses were used in this study. After the OAHT, we collected
serum samples and measured biological antioxidant potential (BAP). We found that BAP began
to increase after the OAHT and was significantly higher in the OAHT group than at 3
(P<0.01) and 7 days (P<0.05) after OAHT than in
the control group at 3 and 7 days after starting collection of blood samples. Therefore,
it was shown that OAHT improved the antioxidant capacity of the horses. 相似文献
