Although feline idiopathic cystitis (FIC) distresses of many cats, its pathogenesis is unknown and the diagnosis is challenging. Polyunsaturated fatty acids (PUFAs) are metabolized into various lipid mediators. Lipid mediators such as prostaglandins (PGs) modulate inflammation and many of them are excreted into the urine. Thus, the investigation of the urinary lipid profile may reveal pathogenesis and help diagnosis of FIC. We collected urine samples from five FIC cats by spontaneous urination and analyzed 158 types of lipid mediators in urines using liquid chromatography-mass spectrometry. The urinary levels of PUFAs were higher in FIC compared to those of the healthy group. The excretions of a major inflammatory mediator, PGD2, were less in FIC. Other well-known inflammatory mediators such as PGE2, PGI2, and their metabolites did not show a difference. In contrast, the levels of PGF2α and its 2 metabolites and PGF3α were higher in FIC. These results may provide new insights into the future management of cat FIC. 相似文献

Feline renal diseases are increasingly noted in veterinary practice. It is important to diagnose and identify the pathological basis of renal dysfunction accurately at an early stage, but there are only a few reports on this area in clinical veterinary medicine. We investigated the efficacy of measurement of urinary albumin (u-Alb) and urinary transferrin (u-Tf) for early diagnosis using 5-µl urine samples collected noninvasively by catheterization from normal (IRIS stage I) cats and cats with stage I chronic kidney disease (CKD). The u-Alb levels in normal and stage I CKD cats were 6.0 ± 4.5 and 11.2 ± 8.4 mg/dl, respectively, and the u-Tf levels were 0.09 ± 0.42 and 0.52 ± 0.79 mg/dl, respectively. Based on ROC curve analysis, the sensitivity and specificity of u-Alb and u-Tf were higher than those of the currently used biomarker, the plasma creatinine level. The sensitivity of u-Alb was higher than that of u-Tf, whereas
the specificity of u-Tf was higher than that of u-Alb. The validity of the threshold albumin level (20 mg/dl) was confirmed by measurements using SDS-PAGE. Since leakage of u-Tf in urine precedes leakage of u-Alb, inclusion of u-Tf in biochemistry tests may be appropriate for IRIS staging as a diagnostic marker of early diagnosis of renal disorder in cats. 相似文献

RAPD markers linked to a clubroot-resistance locus in Brassica rapa L. 总被引:10,自引:0,他引:10

Linkage of random amplified polymorphic DNA (RAPD) markers with resistance genes to clubroot (Plasmodiophora brassicae Wor.)
in Brassica rapa L. was studied in a doubled haploid (DH population obtained by microspore culture. Thirty-six DH lines were
obtained from F1 plants from a cross between susceptible ‘Homei P09’ and resistant ‘Siloga S2’ plants. ‘Homei P09’ was a DH line obtained
by microspore culture of the Chinese cabbage variety ‘Homei’, which is highly responsive in microspore culture. The resistant
line ‘Siloga S2’ was obtained by two rounds of selfing of the fodder turnip ‘Siloga’. Three RAPD markers, RA12-75A, WE22B
and WE49B, were found to be linked to a clubroot-resistance locus. These three markers were linked in the DH lines and an
F2 population and should be useful for marker-assisted selection in breeding programs.

Systemic mycoses were found in 19 (4.7%) of 406 calves less than 6 months old which were autopsied during the past 10 years. Alimentary mycosis occurred in 12 (63.2%) of 19 cases. In alimentary mycosis, mucormycosis showed the highest rate of occurrence (91.7%, 11/12 calves) followed by aspergillosis 41.7% and candidiasis was 9.3%. Mucormycosis and aspergillosis were characterized by focal hemorrhagic necroses with hyphal proliferation and thrombi in the mucosa and muscular layers of the forestomach, abomasum, and small intestine. Candidiasis was characterized by hyperkeratosis with pseudohyphae and microconidia in the mucosa of the omasum. Four of 12 calves (33.3%) had mixed infections of the alimentary tract consisting of Mucorales and Aspergillus species. Pulmonary aspergillosis was found in 10 (52.6%) of 19 calves. There were micro-abscesses with hyphal proliferation or asteroid bodies in the lungs. Infections involving both the alimentary tract and respiratory organs were noted in 3 (10.5%) of 19 calves. Disseminated mycosis was found only in one calf. In alimentary mycosis, administration of antibiotics for the treatment of diarrhea and early weaning were thought to be an important predisposing factor. 相似文献

We genotyped strawberry cultivars by two newly selected and two previously reported SSR markers. All four markers produced interpretable electropherograms from 75 accessions consisting of 72 Fragaria × ananassa cultivars or lines and three octoploid Fragaria species accessions. These SSR markers were highly polymorphic; in particular, one of the newly developed markers, FxaHGA02P13, was capable of distinguishing all of the accessions except for a mutant strain that was derived from another accession in the set. When two markers were combined, all 48 full-sib individuals could be distinguished. Fingerprinting patterns were reproducible between multiple samples, including the leaves, sepals, and fruit flesh of the same accession. Principal-coordinate analysis of the 75 accessions detected several groups, which reflect taxon and breeding site. Together with other available markers, these SSR markers will contribute to the management of strawberry genetic resources and the protection of breeders’ rights. 相似文献

The biotransformation of sulphadimethoxine (SDM) was estimated in liver post-mitochondrial supernatants (S-9) from laying hens. The pathway and activity for hen S-9 were compared with those for cow and pig S-9. The formation of the hydroxylation of SDM, 6-hydroxy SDM (6-OH-SDM), was found only with hen S-9. The N4-acetylating activity of SDM in hen S-9 was lower than in cow and pig S-9. All S-9 from the three species de-acetylated N4-acetyl SDM (N4-AcSDM). With respect to the hydroxylation and N4-acetylation rates in hen S-9, the values incubated at 41 degrees C were higher than those at 37 degrees C (P < 0.01). 相似文献

Trinitrophenylated (TNP) forms of E. coli lipopolysaccharide (LPS) and keyhole limpet hemocyanin (KLH) were used to produce antigen specific plaque-forming cell (PFC) responses with rainbow trout (Salmo gairdneri) splenocytes from unprimed fish in vitro. The culture system that was developed is described and characterized with respect to the kinetics and dose responses for both the haptenated and unhaptenated forms of the carriers. The induction of the PFC response to TNP-LPS was inhibited with TNP-lysine. Exposure to graded levels of gamma-radiation demonstrated a low dose augmentation of the PFC response with both antigens. Antigen addition experiments reveal that both antigens appear to stimulate the same population of antibody-producing B lymphocytes. 相似文献

A new mouse monoclonal antibody (mAb), HUKT was raised against chicken peripheral blood thrombocytes. The mAb HUKT appeared to detect a specific marker on the surface of chicken thrombocytes. Flow cytometry (FCM) analysis revealed that it did not react with cells from the normal thymus, bursa of Fabricius, six kinds of chicken cell lines, chicken erythrocytes or human platelets. In addition, HUKT(+) cells in peripheral blood leukocytes (PBL) were CD45(low), Bu-1a(-) and CD3(-) cells. Immunoblotting analysis showed that the molecule recognized by HUKT is a monomer with an apparent molecular weight of 150 kDa under non-reducing and reducing conditions. Tissue distribution studies revealed that only cells of thrombocyte lineage in bone marrow and embryonic blood cells were stained by HUKT. The HUKT mAb presented here may be useful for both ontogenetic studies of thrombocyte lineage and immunological studies in the chicken. 相似文献

合成滞育激素对家蚕卵Gpase、NAD-SDH、PFK、FBP活性的影响 总被引:2,自引:0,他引:2
二化性蚕品种大造在高温(25℃)明条件(每日光照18小时)下催青时,全部产滞育卵,在低温(16℃)暗条件(全天黑暗)下催青时全部产非滞育卵。低温暗条件下催青的大造在化蛹第3日注射一定剂量的合成滞育激素,可以诱导其产下70%左右左右的滞育卵。这种由合成滞育激素诱导形成的滞育卵,在滞育期中Gpase,PFK,FBP,NAD-SDH等与碳水化合物代谢相关的酶活性与非滞育卵不同,,但与天然滞育卵相似。只是酶活性和蚕卵解除滞育的时间比天然滞育卵有所提高。 相似文献
