H. Wakuri    K. Mutoh  F. Ikeda 《Anatomia, histologia, embryologia》1988,17(2):164-168

The variation of the extensor digitorum brevis (EDB) muscle was examined in 113 hindlimbs of dogs. Four types were discriminated in this muscle. Of the three heads of the muscle, the medial head went to the 2nd digit in types I and II, and to the 2nd and 3rd digits in types III and IV. The middle head went to the 3rd digit in types I and IV, and to the 3rd and 4th digits in types II and III. The lateral head went to the 4th digit in all the types. Type II was the most common of the four (78.76 %). Type III was found in 8.85%, type 1 in 973% and type IV in 2.66%.  相似文献   

Treatment of lead poisoning in wild geese.     

T Murase  T Ikeda  I Goto  O Yamato  K Jin  Y Maede 《Journal of the American Veterinary Medical Association》1992,200(11):1726-1729

Twenty-seven wild geese (Anser albifrons) suffering from lead poisoning caused by ingestion of lead shot were treated with disodium calcium ethylenediaminetetraacetate. The concentration of lead in blood ranged from 0.4 to 23.0 micrograms/ml, with a mean concentration of 5.6 micrograms/ml. In 22 of the birds, 1 to 48 lead pellets (mean, 10.5 pellets/bird) were seen on radiographs of their gizzards. Eleven of 27 birds recovered 3 to 8 weeks after the initiation of treatment. In the birds that recovered, the lead pellets were rapidly eroded as the birds recovered their appetites in response to treatment, and disappeared radiographically between treatment days 17 and 52. The birds that did not survive died within 4 weeks, despite decreased concentrations of lead in blood. Of these 16 birds, 15 had radiographic evidence of impaction of the proventriculus at the first examination and no evidence of resolution of the impaction at the time of death. In contrast, only 2 of the 11 geese that recovered had impaction of the proventriculus at the time of admission. Thus, the condition of the proventriculus seems to be the first consideration to evaluate in the prognosis of lead poisoning in geese.  相似文献

Alterations in biochemical constituents of uterine fluid have been suggested for diagnosis of subclinical uterine infection in the bovine. This study was undertaken to investigate whether uterine fluid biomolecules could act as tool for diagnosis of subclinical endometritis in the buffalo. Uterine fluid samples from normal (n = 22) and subclinical endometritis (n = 18; diagnosed based on uterine cytology)‐affected buffaloes were subjected to biochemical analysis. Among the different biochemical constituents estimated, urea, urea N, cholesterol, total bilirubin and alkaline phosphatase (ALP) concentrations were significantly (p < 0.05) higher in uterine fluid obtained from subclinical endometritis‐affected buffaloes. The extent of difference between normal and subclinical endometritis‐affected buffaloes was highest in ALP (69%) followed by cholesterol (55%), bilirubin (48%), urea (30%) and urea N (30%) concentrations. Receiver operating characteristic (ROC) analysis indicated that the likelihood ratio (LR) was 3.63 for urea, indicating that buffaloes having less than the threshold concentration (47.5 mg/dl) of urea in their uterine fluid were at 3.6 times more risk to be affected with SE. The LRs for urea N, cholesterol, ALP and bilirubin were 2.33, 2.54, 2.12 and 1.65, respectively. It was concluded that ALP, urea, urea N and cholesterol concentrations in uterine fluid may serve as an aid for diagnosing subclinical endometritis in the buffalo.  相似文献   

Cytokinin signaling and its inhibitor AHP6 regulate cell fate during vascular development     

Mähönen AP  Bishopp A  Higuchi M  Nieminen KM  Kinoshita K  Törmäkangas K  Ikeda Y  Oka A  Kakimoto T  Helariutta Y 《Science (New York, N.Y.)》2006,311(5757):94-98

The cell lineages that form the transporting tissues (xylem and phloem) and the intervening pluripotent procambial tissue originate from stem cells near the root tip. We demonstrate that in Arabidopsis, cytokinin phytohormones negatively regulate protoxylem specification. AHP6, an inhibitory pseudophosphotransfer protein, counteracts cytokinin signaling, allowing protoxylem formation. Conversely, cytokinin signaling negatively regulates the spatial domain of AHP6 expression. Thus, by controlling the identity of cell lineages, the reciprocal interaction of cytokinin signaling and its spatially specific modulator regulates proliferation and differentiation of cell lineages during vascular development, demonstrating a previously unrecognized regulatory circuit underlying meristem organization.  相似文献

Spironolactone, but not Eplerenone, Impairs Glucose Tolerance in a Rat Model of Metabolic Syndrome     

Homma T  Fujisawa M  Arai K  Ishii M  Sada T  Ikeda M 《The Journal of veterinary medical science / the Japanese Society of Veterinary Science》2012,74(8):1015-1022

Although some clinical studies have suggested that spironolactone (SPL), a mineralocorticoid receptor (MR) antagonist, appears to increase the blood glucose levels, experimental studies have not supported this notion. Here, we investigated the effect of SPL on blood glucose levels in SHR/NDmcr-cp(cp/cp) (ND) rats, an animal model of metabolic syndrome, in comparison with that of eplerenone (EPL), another MR antagonist. At the same dose of 100 mg/kg, SPL and EPL increased the urinary sodium-to-potassium ratio to a comparable extent, indicating that both agents have similar renal MR antagonistic efficacy in ND rats. Interestingly, SPL but not EPL significantly increased the level of blood glucose. The oral glucose tolerance test revealed that treatment with SPL led to glucose intolerance. The levels of serum insulin and adiponectin, regulators of the blood glucose level, were virtually unaffected by treatment with SPL. On the other hand, SPL induced a marked increase in the blood level of aldosterone, known to be a risk factor for insulin resistance. These results demonstrate that in comparison with EPL, SPL characteristically impairs glucose tolerance in an animal model of metabolic syndrome, in association with a higher blood level of aldosterone.  相似文献   

Evaluation of Efficacy and Safety of Zinc Gluconate Associated with Dimethyl Sulphoxide for Sexually Mature Canine Males Chemical Neutering     

FRM Soto  WG Viana  GCB Mucciolo  FYM Hosomi  CI Vannucchi  CP Mazzei  AR Eyherabide  C De Fátima Lúcio  RA Dias  SS De Azevedo 《Reproduction in domestic animals》2009,44(6):927-931

The aim of this research was to evaluate the efficacy of zinc gluconate associated with dimethyl sulphoxide (DMSO) for chemical neutering in canine males. Fifteen sexually mature male dogs were divided in two groups, named control and treated. An injection was administered to both testicles, at a concentration of 26.2 mg zinc gluconate per ml and 0.5% DMSO in the treated group (11 dogs). The control group was given injections of saline solution (four dogs). Clinical examination and blood collection for a haemogram were done both before and after drug injection. There were 12 spermograms performed to analyse sperm motility, sperm vigour, ejaculate volume, testicle size, pathology and sperm concentrations. Libido was also measured. An ultrasound examination and histopathology were performed at the end of the experiment. Dogs’ libido after chemical injection was reduced by over 50%. The spermogram analysis showed final mean results of 14.54% for sperm motility, 0.72 of sperm vigour and 37 150 per million spermatozoa per millilitre, values considered below the necessary levels at which fertilization can occur. Ultrasound and histopathology analyses of testicles for the treated group revealed more intense injuries when compared with the control group, with compromised testicular parenchyma and a decrease of germ cell number leading to total atrophy, indicating that the treatment reduced the fertilizing potential of male dogs, promoting a possible subfertile status.  相似文献   

Varied occurrence of diverse sulfonylurea‐resistant biotypes of Schoenoplectus juncoides [Roxb.] Palla in Japan,as classified by an acetolactate synthase gene mutation     

Yoshinao Sada  Satoru Kizawa  Hajime Ikeda 《Weed Biology and Management》2012,12(4):168-176

Suspected sulfonylurea (SU)‐resistant Schoenoplectus juncoides plants were collected from rice paddy fields at 24 sites in Japan in order to discover the occurrence pattern of target‐site substitutions on a nationwide scale and at a local field scale. A genetic analysis of the two acetolactate synthase (ALS) genes, ALS1 and ALS2, of the collected plants confirmed that a single‐nucleotide mutation at the Pro₁₉₇, Asp₃₇₆ or Trp₅₇₄ site of either ALS1 or ALS2 existed in each suspected SU‐resistant plant. On a nationwide scale, it was shown that the ALS1 mutations and the ALS2 mutations occurred at a similar frequency, that the P197S and the P197L substitutions were found most frequently among all the substitutions, and that the W574L substitutions (known as global resistance to any ALS‐inhibiting herbicide) were found at a relatively low frequency but in a geographically wide range. In the local field‐scale survey, which was conducted at two sites in Hyogo Prefecture, it was shown that the substitutions were less diverse, compared to on a nationwide scale, probably because the investigation involved a limited number of local fields, and that several substitutions and a susceptible biotype were found in single fields suggesting that a number of collections is required in order to understand the local SU‐resistant status of S. juncoides. In addition, this study reported new findings, that of the P197R, P197T and D376E substitutions in S. juncoides. This set of diverse substitutions in a weed species can be used for further research purposes.  相似文献   

Dairyland populations of bur cucumber (Sicyos angulatus) as a possible seed source for riverbank populations along the Abukuma River,Japan     

Hisami Kobayashi  Shunji Kurokawa  Kentaro Ikeda 《Weed Biology and Management》2012,12(4):147-155

In 2006, the distribution of bur cucumber (Sicyos angulatus L.) along the river bank of the Abukuma River, Japan, was examined. Twenty‐six populations were found in the area surrounding the upper reach of the river and they were limited to dairy land. On the basis of polymerase chain reaction–restriction fragment length polymorphism analysis for four of the six polymorphic loci that were detected in 16 non‐coding regions of the chloroplast DNA from 300 samples, five multilocus haplotypes (A–E) were identified. Despite its smaller size, the surrounding area's population showed a higher genetic diversity at the haplotype level than did the riverbank population. The haplotype composition of the surrounding area's population was similar to that of the riverbank population in the upper‐stream region. The distribution of haplotype D was biased towards the upper reach of the river, possibly because of migration from the surrounding area's population. The distribution of haplotype E was biased towards the middle‐to‐lower reaches of the river and was associated with the existence of source populations other than the surrounding area's population. The results also showed that the estimated seed flow from another dairy land could transport seeds into the middle reach of the river at a high frequency, suggesting that dairy land is largely responsible for the development of the riverbank populations. The eradication of dairyland populations should be given priority in order to prevent future migration along the river bank and to protect the existing endangered wetland species from invasive S. angulatus.  相似文献
