Changes in quantitative profile of extracellular matrix components in the kidneys of rats with adriamycin-induced nephropathy 总被引:1,自引:0,他引:1
Manabe N Kinoshita A Yamaguchi M Furuya Y Nagano N Yamada-Uchio K Akashi N Miyamoto-Kuramitsu K Miyamoto H 《The Journal of veterinary medical science / the Japanese Society of Veterinary Science》2001,63(2):125-133
Extracellular matrix components (ECMs) in histological sections of the kidney cortex from the rats with adriamycin (ADR)-induced nephropathy (5 mg/kg, i.v.) were quantified by an immunohistochemical micromethod. Changes in kidney histopathology and urine and blood biochemistry were investigated. Enlarged kidneys were granular on the surface and pale in color in ADR-treated rats, and these rats had kidneys with glomeruli with expanded mesangial area and with capillary aneurysm. Severe albuminuria, hypoalbuminemia, hypercholesterolemia and disorders in other nephrotic parameters were observed in ADR-treated rats. Type I and IV collagens, fibronectin and laminin contents in the renal cortex of ADR-treated rats at 10 weeks were 329, 317, 263 and 295%, respectively, higher than in each vehicle control, and those at 28 weeks were 1,211, 930, 1,057 and 1,012%, respectively. The glomerular sclerotic abnormalities progressed in a time-dependent manner. Moreover, there was a strong correlation between the ECM levels and serum creatinine and blood urea nitrogen levels. In conclusion, microquantification provided useful information for accurate diagnosis and prognosis of nephrotic lesions and is a good tool to assess the advancement of renal disorders in patients with nephropathy. 相似文献

This study involved screening of wild species of wheat in search of functionally useful seed storage proteins for improvement of breadmaking quality of wheat (Triticum aestivum). After screening of 177 disomic addition lines (DALs) of wheat belonging to different wild species, Aegilops searsii DALs were selected and studied in detail. These DALs of Ae. searsii were from chromosome 1Ss to 7Ss in the background of cultivated wheat cv. Chinese Spring (CS). By analyzing these addition lines, genetic loci of actively expressed genes for the high molecular weight glutenin subunits (HMW‐GS) and gliadin were found on the chromosome 1Ss for the first time and have been designated as Glu‐Ss1 and Gli‐Ss1, respectively. Disomic addition line of chromosome 1Ss (DAL1Ss) showed improved dough strength in different generations compared with CS. SDS sedimentation value and specific sedimentation of DAL1Ss were higher than CS. Mixograph peak height and band width were higher, with no difference in mixing peak time from CS. All these factors indicate a positive effect of quantity as well as quality of gluten proteins of Ae. searsii. This was further supported by increased polymer formation in DAL1Ss because the ratio of unextractable polymeric protein to total polymeric protein (UPP/TPP%) of DAL1Ss was significantly higher than CS. Genes for HMW‐GS (major determinant of end‐product quality in wheat) of Ae. searsii were cloned and sequenced from the DAL1Ss. Phylogenetic analysis of deduced amino acid sequences showed that both x and y HMW‐GS were more similar to that of D genome rather than B genome of wheat. Although S genome is structurally more similar to B genome of wheat, functionally it is more similar to the D genome of wheat and possesses good quality HMW‐GS required for improvement of breadmaking quality of wheat. 相似文献

The present study deals with the successful long-term preservation of feline anti-Toxoplasma gondii antibody activity on filter paper strips stored with silica gel. When filter paper strips were kept at 25 degrees C with silica gel, antibody activity in blood samples was preserved for at least six months. 相似文献

Alstroemeria plants were surveyed for viruses in Japan from 2002 to 2004. Seventy-two Alstroemeria plants were collected from Aichi, Nagano, and Hokkaido prefectures and 54.2% were infected with some species of virus. The
predominant virus was Alstroemeria mosaic virus, followed by Tomato spotted wilt virus, Youcai mosaic virus (YoMV), Cucumber mosaic virus (CMV), Alstroemeria virus X and Broad bean wilt virus-2 (BBWV-2). On the basis of nucleotide sequence of the coat protein genes, all four CMV isolates belong to subgroup IA. CMV
isolates induced mosaic and/or necrosis on Alstroemeria. YoMV and BBWV-2 were newly identified by traits such as host range, particle morphology, and nucleotide sequence as viruses
infecting Alstroemeria. A BBWV-2 isolate also induced mosaic symptoms on Alstroemeria seedlings. 相似文献

In order to find the changes in rainfall characteristics and to examine the flood damage to lowland rice, a statistical analysis
was carried out on the 40-year daily rainfall record at four rainfall stations (Thangon, Paksane, Seno, and Pakse) in Laos.
The rainfall record was divided into two periods of 20 years each. The results of this analysis revealed the trends in changes
regarding the frequency and the timing of the heavy daily rainfall events at the four stations. In Paksane in particular,
heavy daily rainfall events tended to occur in the latter half of the rainy season. 相似文献

A supply and demand model for rice in Cambodia, which includes among other factors evapotranspiration as a water supply variable
impacting regional yields and planted areas, is developed to aid in the design of agricultural policies and planning. Impacts
are determined stochastically by drawing on water cycle distributions and evaluating the resulting variation in production
and price bands for local rice markets. The results of the baseline analyses indicate that production of wet and dry season
rice steadily increases and the consumption per capita slightly decreases due to the negative income elasticity. Results of
a partial stochastic analyses show that the production of rice in regions where elevations are high and the land vulnerable
to flooding are the most sensitive to increased fluctuations in water supply. The changes also affect the rice market through
equilibrium price changes. The upper price band, which is the width between average and 90th percentile, is larger than the
lower band, which is the width between average and tenth percentile, suggesting that the situation of low income consumers
could grow worse under an unstable environment with relatively larger upward price spikes. The results imply that development
of irrigation facilities and water management systems maybe required for Cambodian provinces which rely heavily on agriculture,
particularly rice production, under increasing climatic variation. 相似文献

A 4-year-old female Siberian Husky was diagnosed with pyogranulomatous steatitis at the site of a recurrence of left anal sac rupture (day 1). Carprofen and orbifloxacin were given for 13 days without improvement. A single dose of meloxicam was administered prior to surgical resection of the anal sac, and based on elevated liver enzyme activity, liver supportive therapy was initiated. The dog received carprofen and orbifloxacin orally on the evening of day 14. The dog became anorectic the following morning, and began vomiting. Despite supportive therapy, the dog was unresponsive to treatment and died on day 16. Postmortem examination revealed severe vacuolar change and acute necrosis of hepatocytes consistent with carprofen and meloxicam induced-toxicosis. 相似文献
