We performed a standing hand-assisted laparoscopic ovariectomy in a draft mare that presented with high serum anti-Müllerian hormone (AMH) level and had an enlarged single cystic ovary. Histopathological examination revealed no tumor cell proliferation in the ovary, but the presence of a large ovarian cyst was confirmed. In the diagnosis of abnormal ovaries in mares, a comprehensive assessment should be performed, including the monitoring of ovarian morphology and biomarkers over time, to determine the disease prognosis and treatment plan. The case of this mare with a nonneoplastic abnormal ovary and increased serum AMH level was rare. We suggest that standing hand-assisted laparoscopic ovariectomy is useful for the removal of large ovaries in draft mares. 相似文献

A 7-month-old castrated French bulldog was presented with a left-sided mandibular tumor. The initial tumor biopsy diagnosis was ameloblastoma. The owner brought this dog the Kitasato University Veterinary Teaching Hospital for more detailed examination and treatment. Computed tomography revealed a tumor on the left lateral mandibular gingiva from the caudal third of the incisor tooth to the right canine tooth, associated with severe amorphous osteolysis of the mandibular bone. The tumor was surgically excised and diagnosed as papillary squamous cell carcinoma. Currently, 2514 d (6.9 y) since the operation, the dog is healthy, without recurrence.Key clinical message:Although papillary squamous cell carcinoma is rare, many cases have been reported in the oral cavity of medium-to large-sized dogs. Based on this report, papillary squamous cell carcinoma can occur in small dogs such as young French bulldogs and a good prognosis can be achieved with proper resection. 相似文献

A feeding experiment was conducted to examine the potential use of defatted soybean meal (SBM) and freeze‐dried meat of blue mussel (BM) as partial replacement of fish meal in the diet of tiger puffer. Eight experimental diets were formulated, in which 0, 20, 40 and 60% fish meal protein were replaced with SBM (S0B0, S20B0, S40B0, and S60B0), and 40 and 60% with a combination of SBM and BM (S30B10, S20B20, and S45B15, S30B30). Fish of 11 g initial body weight were fed the diets to satiation twice daily, 6 d/wk for 8 wk at 20 C. Specific growth rate, feed efficiency, and protein efficiency ratio (PER) of fish fed diets containing SBM as an alternative protein source for fish meal decreased with increasing level of SBM, and these parameters of fish fed S40B0 and S60B0 diets were significantly lower than those of the control. Growth of fish in dietary groups containing BM were statistically identical to those in the control, and tended to increase with increasing level of dietary BM both at 40 and 60% substitution levels. Growth and feed utilization of fish fed S20B20 were almost the same to those in the control. 相似文献

Inclusion of the water-soluble fraction of blue mussels Mytilus galloprovincialis as a feed additive was examined with tiger puffer Takifugu rupbripes. The control diet mainly consisted of fish meal, potato starch, and pollack liver oil. Experimental diets were formulated
to replace 30% and 40% of the fish meal protein with defatted soybean meal (SBM), and were supplemented with 0–20% mussel
extracts. Fish of 18 g initial body weight were fed each diet to satiation, twice daily, 6 days per week for 7 weeks at 20°C.
Weight gain and protein efficiency ratio of fish fed the diet containing SBM without the extract were significantly lower
than those of the control at the 30% replacement level. Addition of 5% or 10% extract improved the growth and feed utilization
to levels comparable to those of the control. At 40% substitution, statistically identical growth and feed performance to
the control were obtained for diets supplemented with 10% or 20% extract; however, performance for 5% addition was significantly
lower. Thus, the water-soluble fraction of blue mussels would be an effective feeding stimulant in aquaculture feed for tiger
puffer that makes it possible to replace 30–40% of fish meal protein with SBM. 相似文献

A 90-day oral toxicity test in rats was performed to evaluate the toxicity of
2-tetradecylcyclobutanone (2-tDCB), a unique radiolytic product of stearic acid.
Six-week-old male and female F344 rats (n=15/group) were given 2-tDCB at concentrations of
0, 12, 60 and 300 ppm in a powder diet for 13 weeks. Slight dose-dependent increases in
serum total protein and albumin in male rats were found, but these changes were not
considered to be a toxic effect. The fasting, but not non-fasting, blood glucose levels of
the male rats in the 300 ppm group and female rats in the 60 and 300 ppm groups were lower
than those of the controls. Gas chromatography-mass spectrometry analysis showed
dose-dependent accumulation of 2-tDCB in adipose tissue, notably in males. Next, we
performed an azoxymethane (AOM)-induced two-stage carcinogenesis study. After injection of
6-week-old male F344 rats (n=30/group) once a week for 3 weeks, the animals received
2-tDCB at concentrations of 0, 10, 50 and 250 ppm in a powder diet for 25 weeks. The
incidences of colon tumors for the 2-tDCB dosages were 34%, 45%, 40% and 37%,
respectively, and were not statistically significant. These data suggest that 2-tDCB shows
no toxic or tumor-modifying effects under the present conditions, and that the
no-observed-adverse-effect level for 2-tDCB is 300 ppm in both sexes, equivalent to 15.5
mg/kg b.w./day in males and 16.5 mg/kg b.w./day in females. 相似文献

AFLP-based STS markers closely linked to a fertility restoration locus (Rfm1) for cytoplasmic male sterility in barley 总被引:3,自引:0,他引:3
The Rfm1 gene restores the fertility of the msm1 and msm2 male‐sterile cytoplasms in barley. Rfm1 is located on the short arm of chromosome 6H. To develop molecular markers tightly linked to Rfm1 for use in sophisticated marker‐assisted selection and map‐based cloning, an amplified fragment‐length polymorphism (AFLP) marker system with isogenic lines and a segregating BC1F1 population was used. Nine hundred primer combinations were screened and a linkage map was constructed around the Rfm1 locus by using 25 recombinant plants selected from 214 BC1F1 plants. Three AFLP markers were identified, e34m2, e46m19 and e48m17, linked to the locus. The most closely linked markers were e34m2, at 1.0 cM distally and e46m19, at 1.1 cM proximally. The two AFLP markers were converted to dominant STS markers. These markers should accelerate programmes for breeding restorer lines and will be useful for map‐based cloning. 相似文献

The representative carbon footprint of product (CFP) value of “certified wood in Kyoto Prefecture” was calculated as 241?kg-CO2/m3. The CFP value was 158?kg-CO2/m3 when wood was not kiln dried and final processing was not involved, whereas that of “kiln-dried, finished wood” was 284?kg-CO2/m3. Comparisons of different types of wood were also conducted to examine CO2 emission-reducing effects of “certified wood in Kyoto Prefecture”. We compared the CFP of lumber produced (in Japan) from logs supplied from Japan and other countries and that of “certified wood in Kyoto Prefecture”; the lumber products as a target for comparison are shipped to markets throughout the country. The CFP of “certified wood in Kyoto Prefecture” was approximately 50% lower compared to that of North American wood lumbered in Japan and shipped to markets throughout the country, and about 30% lower compared to the mean CFP of lumber produced (in Japan) from logs supplied from Japan and other countries and shipped to markets throughout the country. We then compared the CFP of “products imported from other countries after being cut into lumber” to that of “certified wood in Kyoto Prefecture”. The CFPs of lumber products from North America and Europe were lower than that of “certified wood in Kyoto Prefecture” (kiln-dried, finished wood). However, when only woodchips were used as a heat source in the process of kiln drying, the CFP of “certified wood in Kyoto Prefecture” was lower than any other kiln-dried lumber products. Regarding “certified wood in Kyoto Prefecture”, the use of woodchips as a heat source in the process of kiln drying or a shift to air drying decreases the CFP. 相似文献

To clarify the effects of tissue and structure of bamboo on its bending properties and set by cooling (bent at 90°C and cooled
to 20°C with bending), the effects of set in bast-fiber-rich (Bfib) and parenchyma-cell-rich (Bpar) specimens were investigated with regard to their dynamic viscoelastic properties, chemical composition, and recovery from
deformation with time. The results are summarized as follows: (1) while no clear effect of the proportion of parenchyma cells
and bast fibers on residual set immediately after cooling was found, the relative recovery from the deformation with time
for Bfib was larger than that for Bpar. (2) Slightly higher lignin content and a-cellulose were seen in Bfib than in Bpar. (3) The peak temperature of loss modulus (E″) found for Bpar, which was attributable to micro-Brownian motion of lignin, was obviously lower than that for Bfib. This was considered to be due to differences in the degree of condensation of lignin or higher-order structure. From these
results, it was deduced that the bastfiber-rich specimen, which showed a higher peak temperature regarding thermal softening
of lignin allowing the induction of insufficient thermal-softening in the range of 20° to 90°C, caused a larger recovery from
deformation with time.
