Palatability of extruded dog diets supplemented with Ascophyllum nodosum L. (Fucaceae, Phaeophyceae)
No full textAlthough Ascophyllum nodosum, a brown seaweed (Phaeophyceae) of the family Fucaceae, is widely used in companion animal products, few studies have attempted to evaluate its influence on foodstuff palatability. This study investigated the effect of A. nodosum on extruded dog food palatability using the split-plate test. Eleven naїve dogs were used. Ascophyllum nodosum (AN) palatability was evaluated across separate tests for three pairwise comparisons between a control extruded food (CTR) and two experimental foods, obtained by adding A. nodosum at low (0.3%, AN-low) or high (1.0%, AN-high) concentrations to the CTR food. Food intake within the first 5 min and first choice eating behaviour was recorded. Differences in food consumption were only registered where the CTR and the AN-high foods were compared (21.11 vs. 7.62 g kg−1 BW0.75; P < 0.001). The intake ratio, calculated as consumed food (A/A + B), confirmed this trend (0.75 vs. 0.28; P < 0.001). No differences were found in first choice behaviour in any palatability test. The results suggest that A. nodosum shows an inhibiting and dose-dependent effect on the dogs dry matter intake. Data obtained from the first choice behaviour evaluation also indicate that negative effects exerted by A. nodosum on palatability are primarily related to gustatory factors rather than to olfactory stimuli

No full textACE-INIBITORI NELLA TERAPIA DELL’INSUFFICIENZA CARDIACA CONGESTIZIA NEL CANE: EFFETTI COLLATERALI A MEDIO E LUNGO
No full textNella terapia dell'insufficienza cardiaca congestizia del cane abbiamo utilizzato, per periodi compresi tra 1 e 17 mesi, farmaci inibitori dell'enzima di conversione dell'Angiotensina (ACE-inibitori), capaci di indurre miglioramenti emodinamici dimostrabili sul piano clinico diretto e strumentale. Tuttavia, in 5 soggetti dei 16 trattati con Enalapril (Enapren "R") o Lisinopril (Zestril "R") alla dose di 0,2 - 0,5 mg/kg/die, abbiamo osservato, a distanza variabile dall'inizio della terapia, la comparsa, in associazione diversa, di insufficienza renale, di arrossamento, grattamento ed ulcere a livello cutaneo, di tosse continua, stizzosa e non produttiva, nonchè di polidipsia. Tali disturbi sono stati interpretati come effetti collaterali legati al tipo di molecola somministrata, poichè sono regrediti con l'interruzione della somministrazione del farmaco o con la sua sostituzione con altro ACE-inibitore. Sulla base delle nostre osservazioni, pur se riferite ad un campione esiguo di soggetti, è ipotizzabile che gli effetti descritti siano più frequenti di quanto noto dalla letteratura e che possano costituire una limitazione alla terapia protratta con ACE-inibitori.
In the therapy of congestive heart failure in dogs inhibitors of the angiotensin converting enzyme was used for variable time from 1 to 17 months due to their ability of inducing haemodynamic improvement demonstrable on a direct and instrumental clinical level. However in 5 of the 16 subjects treated with Enalapril (Enapren "R") or Lisinopril (Zestril "R") at the dose between 0,2 and 0,5 mg/kg/die, at varying time intervals from the beginning of the therapy the appearance in of the following in different combinations were observed: renal failure, cutaneus rashes, scratching and skin ulcers, chronic dry irritative cough, as well as polydipsia. These disorders were interpreted as collateral effects linked with the type of molecule administred since they regressed when the administration of the drug was interrupted or when it was substituted with another ACE-inhibitor. On the basis of these observations, even if they refer to an exiguous sample of subjects, it can be hypothesized that the effects described are more frequent than that is referred by literature and they can constitute a limitation for chronic therapy with ACE-inhibitors

L’ONDA DI OSBORN IN CANI IPOTERMICI
No full textSull'elettrocardiogramma di 8 cani ipotermici, nei quali l'ipotermia era a frigore, è stata evidenziata una deflessione nella congiunzione tra il QRS ed il tratto ST, riconducibile alIa c.d. onda di Osborn (Ow). Questo segno ecgrafico e stato rilevato nel corso di 1 anno nel 25,8% dei soggetti ipo¬termici. Sulla base delle acquisizioni bibliografiche ed in relazione ai rilievi ema¬tochimici denuncianti modificazioni metaboliche, nonchè a queIli istopatologici effettuati nei soggetti venuti a morte, si considera l'Ow espressione della ritar¬data depolarizzazione di un'area miocardica ipotermica.
A peculiar deflection between the QRS complex and the ST segment, identified as the Osborn wave (Ow), has been found on the elec¬trocardiogram of 8 hypothermic dogs affected by a frigore hypothermia. This peculiar electrocardiographic sign has been noticed in the 25.8% of the hypo¬thermic subjects observed during a year. The metabolic changes identified by laboratory exams, and the histopathologic findings in the autoptical examined dogs, suggest that the Ow is probably due to a slow depolarization of a hypo¬thermic myocardial area

Full text linkThe term inflammatory bowel diseases (IBD) refers to a group of idiopathic, chronic intestinal diseases characterized by a diffuse infiltration of inflammatory cells into the lamina propria of the intestine. The pathogenesis of IBD is unknown. The most common signs described are diarrhoea, vomit, and progressive weight loss. In order to make a definitive diagnosis, though, the presence of inflammatory cells infiltration must be evident on histopathologic analysis. The therapeutic approach has 2 main goals: decrease the inflammatory response and remove possible antigenic sources, such as food components or intestinal microflora. Therefore, the most common therapy is the association of Prednisone with a single protein diet, especially when the inflammatory cells infiltration is severe. Another way to reduce the antigenic stimulation is to control the intestinal microflora, so antibiotics and pre/ probiotics may be used. This retrospective study tested and compared the therapeutic value of Prednisone and specific diets, used as a single therapy or combined together. The results show a significative clinical improvement in dogs fed with hydrolized protein diets rather than novel protein diets. Finally, fish is the more reliable source of protein to use during therapy, because of its low ability to trigger an antigenic reaction
