A total of 5204 bulk milk samples were tested for antibodies against bovine viral diarrhea virus (BVDV) classified according to the scheme after Alenius. Forty-five percent of the samples from 2002 were classified as class 0 and class 1, 55% as class 2 and 3. 6420 bulk milk samples from 1997 were classified in an independent study in 65.6% class 0 and 1 and 34.4% in class 2 and 3. In class 0 and class 1 farms only very rarely persistent viremic animals have been found, whereas in class 2 and 3 their presence is highly likely. Our studies with non-selected sera defined the serological screening of bulk milk samples as a promising tool for a possible BVDV eradication program in Bavaria. 相似文献

Recently a new method for capillary blood sampling from the ears of dogs and cats was described, which allows the measurement of glucose concentration by means of portable glucose meters. The authors of this report evaluated the suitability of this method for use by pet owners and the potential technical problems. The owners of seven healthy dogs and seven healthy cats were asked to perform two glucose curves (measuring blood glucose concentration every 2 hours for a total of 12 hours). All dog owners and three cat owners were able to perform a reliable blood glucose curve. The most frequently encountered problems were inadequate formation of a blood drop due to excessive digital pressure on the pinna, repeatedly depressing the plunger of the lancet device instead of allowing the negative pressure to slowly build up, and failure to fill the test strip up to the mark. The authors conclude that these steps of the procedure need to be stressed during technique demonstration and that home monitoring of blood glucose concentrations may serve as a new tool in the management of diabetic dogs and cats. 相似文献

Zusammenfassung Aus Blättern der KartoffelpflanzeSolanum tuberosum Aquila wurde außer Cycloartenol (I), 24-Methylen-cycloartanol (II) (?), Lophenol (III), 24-Methylen-(IV) und 24-Äthyliden-lophenol (V) in 0,05%iger Ausbeute (bezogen auf Blatt-Trockengew.) ein Steringemisch isoliert, das nach dem Molekül-Massenspektrum (Ionisierung durch Anlagerung energiearmer negativer Ladungsträger) aus etwa 49% -Sitosterin (VIII), 36% Stigmasterin (IX), 12% Cholesterin (VI) und 3% Campesterin (VII) zusammengesetzt ist. Weiterhin ließen sich die homologen n-Paraffine C25H52 bis C33H68 und iso-Paraffine C29H60 bis C33H68 (Hauptkomponente mit ca. 51% n-Hentriacontan) sowie geringe Mengen höherer aliphatischer Ketone, vor allem Tritriacontanon, gaschromatographisch bzw. molekülmassenspektrographisch nachweisen.

Summary In addition to cycloartenol (I), 24-methylene-cycloartanol (II) (?), lophenol (III), 24-methylene-(IV) and 24-ethylidene-lophenol (V) a mixture of sterols has been isolated from leaves of the potato plantSolanum tuberosum Aquila (0,05% of the dry weight), which, according to our molecular mass spectrographic investigations employing negative ionization, contains approximately 49% -sitosterol (VIII), 36% stigmasterol (IX), 12% cholesterol (VI), and 3% campesterol (VII). Furthermore the homologous n-alkanes C25H52 to C33H68 and iso-alkanes C29H60 to C33H68 (the main component being n-triacontane with ca. 51%) as well as some higher aliphatic ketones, especially tritriacontanone, have been detected by gas-liquid chromatographic and molecular mass spectrographic methods.

Benign prostatic hyperplasia (BPH) is an age-dependent primarily non-inflammatory enlargement of the accessory gland in the intact dog. The aim of the present study was to control a previously raised suspicion of a breed-related higher incidence of BPH in dogs of the Rhodesian Ridgeback breed. For this, 18 Labrador Retrievers/LR and 20 Rhodesian Ridgebacks/RR were assigned to the age groups 18–24 months (n = 12), 25–48 months (n = 13) and 49–72 months (n = 13). Prostate gland status was determined by rectal palpation, B-mode ultrasound, calculation of the prostate gland volume and semen analysis regarding haemospermia and was classified according to blood plasma concentrations of canine prostate-specific arginine esterase (CPSE) (normal ≤ 60 ng/ml, increased ≥ 61 ng/ml; Pinheiro et al., 2017). Concentrations of testosterone, 5α-dihydrotestosterone and estradiol were analysed in peripheral blood serum or plasma for detecting breed-specific conditions regarding the endocrine metabolism. Prostatic volume was significantly larger in RR irrespective of the CPSE status. In RR, BPH occurred more frequently and started at an earlier age compared with the LR. Breed-related specificities in steroid metabolism in the RR were indicated by correlations of 5α-dihydrotestosterone and estradiol with age and of testosterone with prostate gland volume. Although the incidence of sonographic signs of BPH and haemospermia did not fit with normal and increased CPSE concentrations, a breed-specific higher incidence of BPH in the RR breed could be clearly verified. 相似文献

Loss of the caudal maxilla and ventral orbit after tumor resections can have negative functional and esthetic influences on the eye involved. This article reports on a case of a caudal maxillary acanthomatous ameloblastoma involving the ventral orbit that was resected and stabilized with a masseter muscle flap. The masseter muscle flap was generated from the superficial belly of the masseter muscle in order to close a defect in the orbital rim, created by a caudal maxillectomy. None of the published complications such as enophthalmos, excessive lacrimation, globe deviation, or strabismus were noted, 8 months following the procedure. The only clinical sign present at the time of re‐evaluation was mild lacrimation. The authors propose the use of a masseter muscle flap as a viable technique in stabilizing the ventral orbit after caudal maxillectomy and ventral orbitectomy, preventing the complications associated with this surgery. 相似文献

The bistability in the position of the two hydrogen atoms in the inner cavity of single free-base naphthalocyanine molecules constitutes a two-level system that was manipulated and probed by low-temperature scanning tunneling microscopy. When adsorbed on an ultrathin insulating film, the molecules can be switched in a controlled fashion between the two states by excitation induced by the inelastic tunneling current. The tautomerization reaction can be probed by resonant tunneling through the molecule and is expressed as considerable changes in the conductivity of the molecule. We also demonstrated a coupling of the switching process so that the charge injection in one molecule induced tautomerization in an adjacent molecule. 相似文献
