Four dogs diagnosed as pituitary-dependent hyperadrenocorticism were treated with transsphenoidal hypophysectomy and postoperative hormone supplementation therapy. On histological examination of the resected tissues, the tumors were ACTH-producing adenoma of the anterior lobe. Clinical signs such as alopecia and calcinosis cutis, as well as endocrinological abnormalities, were markedly alleviated after surgery. The clinical courses of these 4 dogs suggest that transsphenoidal hypophysectomy may be a useful treatment for pituitary-dependent hyperadrenocorticism.  相似文献   

Plasma concentration of estrone sulfate during pregnancy in different breeds of Japanese beef cattle     

Isobe N  Nakao T  Uehara O  Yamashiro H  Kubota H 《The Journal of reproduction and development》2003,49(5):369-374

Plasma concentrations of estrone sulfate in different breeds of Japanese beef cattle and the relationship between those concentrations and feto-placental growth were examined in order to assess the possibility of monitoring abnormal growth of the fetus. Blood samples were obtained from cows from day 90 of gestation to parturition. The plasma concentration of estrone sulfate was measured by direct enzyme immunoassay. From day 180 of gestation, the mean concentration of estrone sulfate increased gradually and it was drastically elevated after day 240 of gestation with the maximum at day 285. Plasma concentrations of estrone sulfate on day 240 of gestation was significantly increased in F(1) cows (Holstein Friesian and Japanese Black) compared with those in other breeds of cow. From day 270 to 278 of gestation, estrone sulfate concentrations of Holstein Friesian cows inseminated by Holstein Friesian differed from those inseminated by Japanese Black. In the cow with retained placenta, the plasma concentration of estrone sulfate reached plateau at day 240 of gestation and did not increase thereafter. There was no significant relationship between estrone sulfate concentration and duration of gestation, calf birth weight, weight of placenta or viability of newborn calves. These results indicate that changes of plasma estrone sulfate concentration in Japanese beef cattle are very similar to those in Holstein dairy cattle. They also suggest that the plasma concentration of estrone sulfate is associated with the breed of pregnant cow and that its concentration is also affected by calf birth weight depending on the breed of bull. It seems possible to predict the incidence of retained placenta but not the calf birth weight and viability of newborn calves in Japanese beef cattle.  相似文献   

Enzyme immunoassay of Dirofilaria immitis-specific IgE in infected dogs     

L J Gershwin  G R Yamagata  M M Wong 《Veterinary parasitology》1988,30(1):45-56

An ELISA procedure was developed for monitoring the specific IgE response in dogs to Dirofilaria immitis infection. The results of this assay correlated well with, and appeared to be more sensitive than, the passive cutaneous anaphylaxis test. The IgE ELISA values of the positive reference serum and the passive cutaneous anaphylaxis test results showed that a serum to negative absorbance ration of 1.45 was statistically significant for discrimination and was used to evaluate the specific IgE response in the sera from 90 clinically diagnosed heartworm cases. This ELISA procedure was more sensitive, as it detected 78% of the 90 cases as compared to a detection rate of only 43-47% by IgG ELISA or IFA. Sera obtained from 23 experimentally infected dogs at 4-week intervals for 20 weeks post-infection, were assayed for D. immitis-specific IgE by ELISA. A group of the infected dogs was also treated with diethylcarbamazine during the course of infection. All the experimentally infected dogs developed a specific IgE response, with treated dogs generally responding earlier.  相似文献   

Morphological survey of bovine Setaria in the abdominal cavities of cattle in Aomori and Kumamoto Prefectures, Japan     

Nakano H  Tozuka M  Ikadai H  Ishida H  Goto R  Kudo N  Katayama Y  Muranaka M  Anzai T  Oyamada T 《The Journal of veterinary medical science / the Japanese Society of Veterinary Science》2007,69(4):413-415

An epidemiological survey of bovine Setaria collected from the abdominal cavities was performed morphologically on the cattle in Aomori and Kumamoto Prefectures, Japan, between August 2005 and July 2006. Fifty Setaria worms were collected from the cattle in Aomori Prefecture and 847 from those in Kumamoto Prefecture. Of these worms, 35 were identified as Setaria digitata, 14 as S. marshalli, and one as S. labiatopapillosa in Aomori Prefecture, while 816 were identified as S. digitata and 31 as S. marshalli in Kumamoto Prefecture.  相似文献

Evaluation of the umami taste intensity of green tea by a taste sensor     

Hayashi N  Chen R  Ikezaki H  Ujihara T 《Journal of agricultural and food chemistry》2008,56(16):7384-7387

A method for evaluating the umami taste intensity of green tea by a taste sensor system was established. Interference in the measurement from catechins was solved by removing the catechins from sample solutions with poly(vinylpolypyrrolidone). A 5.00 mM aqueous solution of glutamic acid monosodium salt was used as the standard solution. Sensor outputs were converted into EIT uma (estimated intensity of taste concerning umami) values. One unit on the EIT uma scale was defined as the amount of the sensor output corresponding to a difference in 1.2 times the concentration of the standard substance (glutamic acid monosodium salt). The umami taste intensity of green tea was classified into six grades on the EIT uma scale. Sensory tests proved that the EIT uma value had a high correlation to the human gustatory sense.  相似文献   

Seasonal characteristics of surface water quality in the wastewater catchment system of an urbanizing basin     

Masaomi Kimura  Keigo Noda  Tatsuya Makino  Hijiri Yamagata  Somphasith Douangsavanh  Keoduangchai Keokhamphui  Hiromasa Hamada  Masashi Kiguchi  Toshiaki Iida  Kazuo Oki 《Paddy and Water Environment》2018,16(3):519-531

Vientiane, Lao PDR, has been subject to extensive and ongoing urbanization plans, including development of natural marshes and residentialization of paddy fields into suburban areas, despite natural marshes playing a vital role in treating wastewater from urban areas. Therefore, it is important to understand the current situation regarding the nutrient balance in these natural wastewater treatment systems to predict future conditions and design appropriate measures against water quality deterioration. However, limited data are available in Vientiane on the hydrological characteristics of water and nutrient runoff that flow into marshes through drainage canals. In this study, we conducted a periodic survey of drainage canals and Mak Hiao River in the wastewater catchment system surrounding Vientiane during the rainy and dry seasons. We monitored the discharge of surface water at 21 observation sites and analyzed water quality of nitrogen, phosphorus, and total organic carbon. These observations revealed that the concentrations of dissolved nitrogen and phosphorus were significantly higher at sites in urban areas, followed by sites in the main river basin and those in agricultural areas. Dissolved nitrogen and phosphorus concentrations varied with runoff discharge, especially in urban and river basin sites, with lower concentrations in the rainy season and higher concentrations in the dry season. On the other hand, we found no significant differences between the rainy and dry seasons in nutrient concentrations in the agricultural basin. Finally, we proposed measures to counteract the deterioration of water quality during dry seasons and simulated the impact of these measures.  相似文献
