The anatomical variations of the portal vein and the hepatic artery ramifications were analysed on liver corrosion casts in 20 dogs as a possible aid in the surgical management of the organ. The portal vein ramified similarly in all dogs. It divided into the smaller right portal branch from which vessels for the caudate process and both right lobes arose and the substantial left portal branch, which supplied the remaining liver portions and in 12 cases also the dorsal part of the right lateral lobe. Right lateral, right medial and left branches are the major arteries originating from the hepatic artery; however, their origin and course varied among individual animals. In 10 livers, the right lateral and the left branches originated from the hepatic artery, while the right medial branch arose from the left branch and usually supplied the right medial lobe solely. In nine livers, the right medial branch arose directly from the hepatic artery and supplied quadrate lobe and gallbladder as well, while in one liver the common artery, which subsequently divided into lobar branches, branched away from the hepatic artery. An additional branch for the caudate process, originating directly from the hepatic artery, was observed in 10 livers. Certain liver portions received the arterial blood from two major branches, which was particularly characteristic for the right medial lobe (six livers) and caudate process (10 livers). The course of the major arterial branches was also variable, although they proceeded in close anatomical relationship with the portal vein branches. The left arterial branch accompanied the left portal branch on its dorsal aspect (15 cases) or crossed it from the caudal aspect (five cases). The right lateral branch crossed the initial parts of the left and right portal branches either from cranial (12 cases) or caudal aspects (eight cases), while the right medial branch always crossed the left portal branch from its caudal aspect.  相似文献   

Alternative cleaning of compost leachate using biopolymer chitosan

Compost leachate poses a threat to the environment because it contains many organic and inorganic pollutants. Chemical Oxygen Demand (COD) has been reported at values above 5000 mg/l O₂. Heavy metals, such as nickel, lead, chromium are also present within these waters. Thus, in order to comply with the increasingly stringent environmental quality standards such contaminants must be removed effectively. The research approach in this paper is directed towards chelating pre-treatment procedures. Nontoxic and biodegradable biopolymer chitosan was used as a chelator for the removal of dissolved metals from compost leachate. The influence of chemical conditions regarding the chelation efficiency was studied in model solutions. The optimal treatment conditions were applied onto compost leachate which was analysed further regarding metals. In addition, the influence of chitosan was studied on compost leachate toxicity. The most important aspect of this paper is to demonstrate the potential of waste chitosan recycling. Thus, the chitosan chelates were subjected to the electrospinning procedure in order to develop new nano-porous structures, such as, for example, conductive textiles.  相似文献

Survival of a dog with pneumonia caused by Mycobacterium fortuitum     

G H Turnwald  R D Pechman  J R Turk  T N Hribernik  H U Cox  D R Waldron  A Roy  L Burnett  E Smith 《Journal of the American Veterinary Medical Association》1988,192(1):64-66

Pneumonia caused by Mycobacterium fortuitum was diagnosed in the left lung lobes of a 3-year-old male Samoyed. Unilateral pneumonectomy and antibiotic treatment (primarily amoxicillin trihydrate-clavulanate potassium and kanamycin) were associated with resolution of the pneumonia. In dogs, M fortuitum causes pulmonary disease that radiographically resembles bacterial pneumonia. Therefore, M fortuitum infection should be considered in dogs with radiographic signs of bronchopneumonia that worsen despite antibiotic treatment.  相似文献   

Lymphocyte transformation suppression caused by pyoderma--failure to demonstrate it in uncomplicated demodectic mange   总被引：1，自引：0，他引：1  

O Barta  C Waltman  P P Oyekan  R K McGrath  T N Hribernik 《Comparative immunology, microbiology and infectious diseases》1983,6(1):9-18

Three dogs with demodectic mange uncomplicated by a bacterial infection and 9 dogs with demodectic mange and pyoderma were tested for their lymphocyte response to phytomitogens in vitro and for the presence of the serum's lymphocyte immunoregulatory factors (SLIF) suppressing blastogenesis. None of the 3 dogs with uncomplicated demodectic mange showed any detectable dysfunction of their lymphocytes or presence of the blastogenesis suppressing SLIF. Their lymphocytes generally responded to the mitogens with more blastogenesis than lymphocytes from healthy controls. On the other hand, in the group of 9 dogs with demodicosis complicated by a bacterial infection, high levels of the blastogenesis suppressing SLIF for concanavalin A-sensitive cells were detected in 4 dogs, for phytohemagglutinin-sensitive cells in 2 dogs, and for pokeweed mitogen-sensitive cells in 1 (of only 3 tested) dog. Dysfunction of lymphocytes per se (detected by a decreased blastogenesis in nonsuppressive normal canine and bovine sera) was detected in 3 dogs with demodicosis with pyoderma. The success of the treatment of demodectic mange or the bacterial skin infection did not correlate with the previous presence or absence of the blastogenesis suppressing SLIF. The treatment of pyoderma was less successful in dogs with an increase in blastogenesis of unstimulated cells in fresh normal canine serum over that in autologous serum. All 3 dogs with a detected dysfunction of their lymphocytes either died or were euthanatized as untreatable cases. It is concluded that the development of demodectic mange per se did not cause the appearance of the blastogenesis suppressing SLIF, which was primarily related to the appearance and extent of the secondary bacterial skin infection.  相似文献   

Complications following thiacetarsamide sodium therapy in Louisiana dogs with naturally-occurring heartworm disease     

J D Hoskins  T N Hribernik  M T Kearney 《The Cornell veterinarian》1985,75(4):531-539

Four hundred and sixteen dogs with naturally-occurring heartworm disease were evaluated for complications following thiacetarsamide sodium therapy. Of these, 109 dogs (26.2%) experienced complications. Increased lung sounds was the most commonly seen complication, followed by fever and coughing. In dogs with complications, 83.5% of them presented without clinical evidence of pulmonary thromboembolism or heart failure. There were no statistically significant differences between the age, sex, breed and body size of dogs that experienced complications following thiacetarsamide therapy and dogs that did not. Complications were most frequently seen 5 to 9 days following thiacetarsamide therapy although some dogs experienced initial complications as late as 28 days. Thirty-three of 109 dogs (33.0%) with complications responded to exercise restriction. The remaining 76 dogs with complications prior to or following thiacetarsamide required adjunct drug therapy. Of these, 35 dogs responded favorably to anti-inflammatory doses of prednisolone or prednisone. Five dogs died or were euthanatized because of the complications experienced. Eighteen of 416 dogs (4.3%) presented with clinical evidence of pulmonary thromboembolism or heart failure prior to the thiacetarsamide therapy. All 18 dogs experienced complications in spite of adjunct drug therapy and exercise restriction prior to, during, and following thiacetarsamide therapy. Survival rate following resolution of the thiacetarsamide-induced complications was greater than 98%.  相似文献   

Homogeneous self-cleaning coatings on cellulose materials derived from TIP/TiO2 P25     

Nika Vero  Silvo Hribernik  Patrizia Andreozzi  Majda Sfiligoj-Smole 《Fibers and Polymers》2009,10(5):716-723

The aim of this research was to study TiO₂ nanocoatings formation and to investigate their self-cleaning effects when applied on cellulose materials. Two different approaches for achieving nanocoatings were used. First, coatings were generated in situ through an acid and alkaline catalyzed sol-gel process with or without added water. Another type of coatings was prepared starting from commercial TiO₂ P25 powder. In order to acquire homogeneous coatings from TiO₂ P25 nanoparticles with uniform nanoparticles size distribution, pH of aqueous TiO₂ P25 dispersions was varied. The dispersion preparation conditions were studied by dynamic light scattering (DLS) and zeta potential (ζ-potential) analysis. The resulting TiO₂ nanocoatings were analyzed in terms of their surface morphology using scanning electron microscopy (SEM). Nanocoatings obtained from pure aqueous dispersions of TiO₂ P25 nanoparticles were inhomogeneous with huge agglomerates; however by changing the pH of dispersion and consequently changing the surface charge of TiO₂ P25 nanoparticles as well, more homogeneous nanocoatings with uniform TiO₂ nanoparticles distribution were prepared. Significant differences between solgel derived coatings were observed. Sol-gel process without added water yielded more homogeneous coatings than sol-gel process with addition of water. Completely different surface morphologies were obtained using alkaline or acid catalyst. Acid catalyzed sol-gel process yielded nanocoatings with long, extended, thin structures; contrary, under alkaline conditions particles grow in size with decrease in number. Fourier transform infrared (FTIR) spectroscopy was used to study the coatings’ microstructure. Furthermore the formation of mono-disperse nanoparticles on the fiber surface resulted in enhanced photocatalytic activity. Degradation of colored stain applied on TiO₂-treated samples was investigated by colorimetric measurements. Photocatalytic activity of nanocoatings prepared via acid catalyzed sol-gel process without water addition was comparable to that of nanocoatings derived from aqueous dispersions of commercial TiO₂ P25 nanoparticles.  相似文献   

Diskospondylitis associated with Brucella canis infection in dogs: 14 cases (1980-1991).     

S C Kerwin  D D Lewis  T N Hribernik  B Partington  G Hosgood  B E Eilts 《Journal of the American Veterinary Medical Association》1992,201(8):1253-1257

A retrospective study of 135 dogs with diskospondylitis revealed 14 dogs with concurrent Brucella canis infection. Sexually intact male dogs and dogs in the southeastern United States appeared to be at higher risk. Results of bacteriologic culturing of blood were less likely to be positive for dogs with diskospondylitis caused by B canis infection than for dogs with diskospondylitis caused by other organisms. Follow-up evaluation of 13 of the 14 dogs revealed complete remission of clinical signs in nine, but serologic test results continued to be positive for B canis infection long after resolution of clinical abnormalities. Radiographic follow-up evaluation in 6 dogs revealed active lesions despite complete remission of clinical abnormalities.  相似文献
