The contents of diterpenoids, ginkgolides A, B, and C, in seeds, embryos, and plantlets ofGinkgo biloba were analyzed to clarify the relations between organogenesis and terpene contents inG. biloba. There is so far no published report on the contents and changes in such terpenes in seeds and very young plantlets ofG. biloba. Ginkgolides were present in seeds and embryos. Plantlets cultured in both the dark and under illumination contained substantial amounts of ginkgolides, more abundant than in seeds and embryos. It is concluded that ginkgo yields ginkgolides in its early stage of development regardless of light. 相似文献

A highly viscous polysaccharide solution was extracted from Gagome Kjellmaniella crassifolia in 20°C water. The eluted sugar concentration was 0.16%, and the extracted carbohydrates consisted of fucoidan, laminaran,
and alginate at an approximately ratio of 8.2:0.8:1.0. An increase in the extraction temperature resulted in a less viscous
solution, even though the amount of eluted sugar was higher than that obtained at a lower temperature. The most viscous extraction
solution was obtained at a neutral pH, with a more acidic or alkaline extraction solution being a less viscous. When the
highly viscous polysaccharide solution was heated, the viscosity decreased markedly with increasing temperature. The viscosity
of the polysaccharide solution increased after dialysis against water and decreased with the addition of either KCl or NaCl.
However, the viscosity was recovered to previous levels by following re-dialysis against water. The removal of divalent cations
by EDTA and the re-addition using CaCl2 or MgCl2 also caused reversible changes to the viscosity. These characterizations will be useful for widespread applications of viscous
K. crassifolia polysaccharides. 相似文献

To clarify the genetic mechanism which controls the variation in amylose content among nonwaxy landraces of foxtail millet,
the inheritance of different starch types in endosperm was examined by I2-KI staining. The level of starch granule bound protein in foxtail millet endosperm was also analyzed using SDS-PAGE. The
segregation for starch types in F2 and F3 seeds determined by I2-KI staining showed that there are three different alleles at the waxy (wx) locus. A major protein bound to starch granules
was detected in nonwaxy endosperm but it was absent in most of the waxy endosperm, suggesting that the protein is the Wx gene
product which is responsible for the synthesis of amylose in endosperm. The level of Wx protein proportionally corresponded
to the amylose content among nonwaxy landraces. This implies that two different Wx alleles regulate quantitative levels of
Wx protein. Landraces with the allele for low amylose content are from Taiwan, the Philippines, Indonesia and Thailand.

Red-crowned cranes Grus japonensis, which are an endangered species, have two separate populations, a mainland population in the Eurasian continent and an island population in eastern Hokkaido, Japan. Island cranes showed three haplotypes (Gj1, Gj2 and Gj13), whereas ten haplotypes (Gj3–Gj12) were confirmed in captive cranes and stray cranes. We found Gj5 haplotype in feathers of two cranes as well as four new haplotypes in seven wild crane feathers collected in South Korea. We also found feathers in the nest in Sarobetsu Wetland in northwestern Hokkaido. While the haplotype of female-derived feathers was Gj2, that of male-derived feathers was Gj5. The results suggest that there has been crossbreeding between cranes in the island population and cranes in the mainland population. 相似文献

Canine degenerative myelopathy (DM) is a progressive neurodegenerative disease of the spinal cord. The diagnosis is based on the observation of clinical signs, genetic testing, and exclusion of other spinal cord diseases, and a definitive diagnosis of DM can only be confirmed by postmortem histopathological findings. The aim of this study was to investigate the diagnostic ability of diffusion tensor imaging (DTI) for DM. Eight DM-affected Pembroke Welsh Corgis, thirteen dogs with thoracolumbar intervertebral disk herniation (IVDH), and six healthy control dogs were included. All dogs were scanned using a 3.0-T MRI system. Apparent diffusion coefficient (ADC) and fractional anisotropy (FA) values were calculated for each intervertebral disk level slice between T8–T9 and L2–L3 intervertebral disk levels, and the entire area of the thoracolumbar spinal cord between T8–T9 and L2–L3 intervertebral disk levels (T8–L3 region). The ADC and FA values of the T8–L3 region were significantly lower in the DM group than in the IVDH group. The ADC values for the T8–L3 region had a moderate negative correlation with clinical duration (rs= −0.723, P=0.043); however, the FA values of other intervertebral disk levels and T8–L3 region had no correlation with clinical durations. The measurement of DTI indices can be used to quantitatively assess neurodegeneration and may have diagnostic value for DM. In particular, the ADC value of the T8–L3 region may aid in making a non-invasive premortem diagnosis of DM. 相似文献

A 1-year- and 11-month-old spayed female toy poodle had showed progressive ataxia and paresis in the hindlimbs since 11 months old. Magnetic resonance imaging revealed high signal intensity on T2-weighted and fluid-attenuated inversion recovery images at the thoracic and lumbar spinal cord. The dog’s neurological condition slowly deteriorated and flaccid tetraparesis was exhibited. At 4 years and 11 months old, the dog died of respiratory failure. On postmortem examination, eosinophilic corkscrew bundles (Rosenthal fibers) were observed mainly in the thoracic and lumbar spinal cord. Histological features were comparable to previously reported cases with Alexander disease. This is a first case report to describe the clinical course and long-term prognosis of a dog with Alexander disease. 相似文献

A 4-year-old female French bulldog presented with a 6-month history of
right-sided head tilt and acute onset ataxia. Magnetic resonance imaging (MRI) showed a
large mass lesion at the cerebellomedullary pontine angle. The dog was able to stand and
walk after beginning symptomatic therapy with prednisolone, acetazolamide and glycerin.
Magnetic resonance imaging 10 months after the first examination indicated slight
expansion of the tumor. The dog was able to walk with continuous symptomatic therapy for
15 months until death, although the head tilt persisted. On postmortem examination, the
gross tumor was slightly larger than when seen on the second MRI scan and was
histopathologically diagnosed as a choroid plexus papilloma. 相似文献

Renal impairment is concurrent with adverse outcomes such as heart disease in humans and dogs. Intrarenal Doppler ultrasonography (IRD) is used to assess intrarenal hemodynamics, and resistance index (RI) and venous impedance index (VII) are used to evaluate intrarenal hemodynamics in humans with heart failure. However, only a few studies have assessed the efficacy of IRD, especially VII, in dogs, and the methods differ between studies. Additionally, repeatability, reproducibility, and factors influencing IRD values have not been validated in dogs. This prospective, analytical study aimed to assess repeatability and reproducibility of IRD, and to clarify influencing factors of IRD in dogs without heart disease. We enrolled 78 dogs without heart disease. The RI and VII were highly reproducible, and the reference intervals for VII were 0.13–0.37. Differences in transducer (sector and convex) and posture (right lateral and supine decubitus position) had no effect on the IRD values. In contrast, RI and VII were higher in the renal vessels than in interlobar vessels. Age affected RI values (r = 0.39, P < 0.001), but there was no correlation between age, body weight, and VII. In conclusion, IRD is a repeatable and reproducible method to assess intrarenal hemodynamics in dogs. The findings also suggest that age should be considered while interpreting RI. 相似文献
