Effects Of Salinity On The Osmoregulatory Functions Of The Gills In Nile Tilapia (Oreochromis Niloticus), Yusuf Güner, Osman Özden, Haşmet Çağirgan, Muhammet Altunok, Volkan Kizak

Turkish Journal of Veterinary & Animal Sciences

Changes in branchial Na^+-K^+-ATPase activity, and the number and size of chloride cells resulting from the transfer of fish into seawater were investigated in tilapia (Oreochromis niloticus) (22.03 -+ 0.91 g), which were transferred to full strength seawater (36‰) directly and for 14 days. Whole mortality occurred when the tilapia were transferred into seawater directly. That is, no acclimation was allowed. Branchial chloride cell numbers decreased after seawater exposure, whereas a gradual increase was observed in chloride cell sizes. However, the chloride cells of seawater-adapted individuals showed a 2-fold increase in size (P < 0.05). Initially 5‰ and 10‰ salinity resulted in lowered branchial Na^+-K^+-ATPase activity but then this activity increased and the highest activity was at 25‰ salinity (P < 0.01). This study demonstrated the effects of high salinity through direct and gradual acclimations on branchial Na^+-K^+-ATPase activity and chloride cell abundance.

Urokinase And Urokinase Receptor In The Urinary Tract Of The Dog, Trina Racquel Bailey Jan 2005

Urokinase And Urokinase Receptor In The Urinary Tract Of The Dog, Trina Racquel Bailey

LSU Master's Theses

Urokinase (uPA) and urokinase receptor (uPAR) are present in the urinary tract of people, mice, rats and cows. The presence of urokinase and urokinase receptor in the urinary tract of dogs has not been documented. Documenting the presence of uPA and uPAR in the urinary tract of healthy dogs will help determine the role these proteins play in pathology of the urinary tract in further research. Urine was collected from fifty-four healthy dogs. A fluorescence assay was developed using the fluorogenic substrate Z-Gly-Gly-Arg-AMC, HCl. This assay documented presence of active uPA-like protein in concentrated urine. A direct sandwich ELISA assay …

The Influence Of Transdermally Administered Fentanyl On Isoflurane Requirements In Normothermic And Hypothermic Dogs, Diane Wilson Jan 2005

The Influence Of Transdermally Administered Fentanyl On Isoflurane Requirements In Normothermic And Hypothermic Dogs, Diane Wilson

LSU Master's Theses

Intraoperative reductions in serum fentanyl levels in dogs with induced moderate hypothermia and transdermal fentanyl patches (TDF) in place has been documented. The impact of such reductions has not been evaluated nor has the anesthetic sparing effect of the TDF. Reductions in serum levels may be the result of either a decreased uptake of fentanyl from the dermal depot, or a biophase shift. The objective of this investigation was to determine whether the minimum alveolar concentration (MAC) of isoflurane was altered in the presence of TDF in normothermic and hypothermic dogs. Six mature, healthy, mixed breed dogs were anesthetized on …

Cetacean Brain Evolution: Multiplication Generates Complexity, Lori Marino Dec 2004

Cetacean Brain Evolution: Multiplication Generates Complexity, Lori Marino

Anatomy Collection

Over the past 55-60 million years cetacean (dolphin, whale, and porpoise) brains have become hyperexpanded so that modern cetacean encephalization levels are second only to modern humans. At the same time, brain expansion proceeded along very different lines than in other large-brained mammals so that substantial differences between modern cetacean brains and other mammalian brains exist at every level of brain organization. Perhaps the most profound difference between cetacean and other mammalian brains is in the architecture of the neocortex. Cetaceans possess a unique underlying neocortical organizational scheme that is particularly intriguing in light of the fact that cetaceans exhibit …

The Characterization Of Clays And Cetylpyridiniumexchanged Clays For Their Ability To Adsorb Zearalenone, Komkrich Pimpukdee, Bundit Tengjaroenkul, Prapansak Chaveerach, Benjamas Mhosatanun Dec 2004

The Characterization Of Clays And Cetylpyridiniumexchanged Clays For Their Ability To Adsorb Zearalenone, Komkrich Pimpukdee, Bundit Tengjaroenkul, Prapansak Chaveerach, Benjamas Mhosatanun

The Thai Journal of Veterinary Medicine

The adsorption of zearalenone (ZEN) onto Ca-montmorillonite (STx-1), Na-montmorillonite (SWy-2), acid-activated montmorillonite (AAM), clinoptilolite and cetylpyridinium (CP) exchanged clays was studied. The results indicated that CP-exchanged clays were more effective than unmodified base clays in adsorbing ZEN, i. e. STx-1 (7.4±2.3 mg/g) < clinoptilolite (7.6±1.1 mg/g) < AAM (10.0±0.0 mg/g) < SWy-2 (11.9±0.4 mg/g), whereas the extent of ZEN adsorption into modified clay products did not follow the order seen in the based clays. The adsorption efficiency of CP-exchanged clays is in the order of CP*STx-1 (56.9±1.1 mg/g) = CP*AAM (56.9±1.8 mg/g) > CP*SWy-2 (47.9±2.6 mg/g) > CP*clinoptilolite (15.5±1.1 mg/g). Three CP-exchanged clays were further characterized by isotherm studies. The results indicated that the isotherm shapes of CP*exchanged clays exhibited a S-shape. The isotherm plot is concave up to the inflection point and then plateaus, which suggests multiple, specific binding sites and saturation at each site. It is important to rigorously test …

The Thai Journal of Veterinary Medicine

The purpose of this research was to evaluate the relationship between histopathological appearance and clinical data, Argyrophilic Nucleolar Organizer Regions (AgNORs) and Proliferative Cell Nuclear Antigen (PCNA) indices in canine oral melanoma. A retrospective study was performed on biopsy specimens from 67 dogs submitted over the year 2000 to 2003 to the Department of Pathology, Faculty of Veterinary Science, Chulalongkorn University. Our results showed that the average AgNORs index did not show any significant differences with histopathological characteristics and Masson-Fontana Silver (MFS) stain but the AgNORs index showed significant differences when compared with histological grading and tumor diameter size (p < 0.05). The average PCNA index did not show significant differences with histopathological characteristics, grading, and MFS stain but did not show significant differences with the sex of affected dogs and tumor diameter size (p < 0.05). AgNORs and PCNA indices might be useful as a prognostic factor for oral melanoma in dogs

The Thai Journal of Veterinary Medicine

The study looked at the relationship between the expression of c-erbB2 oncogene protein, histological types, PCNA and AgNORs indices, in feline mammary tumors. Sixty, surgically resected, mammary tumors from cats were collected and histological processed. The expression of c-erbB2 oncogene protein was detected by immunohistochemistry and was seen in benign hyperplasia, adenosis and malignant groups. The c-erbB2 oncogene protein expression in malignant, feline mammary tumors was 41.67% (25/60) which could be divided into simple tubular ACC, 25% (6/24), simple papillary ACC, 78.6% (11/14), solid carcinoma, 26.7% (4/15) and cribiform carcinoma, 57.14% (4/7). There were statistically significantly differences (p<0.05) in the expression of c-erbB2 oncogene protein between simple tubular ACC, compared with simple papillary ACC and solid carcinomas. The expression of c-erbB2 oncogene protein in specimens, classified by histological malignancy grades revealed, grade I, 42.11% and grade II, 41.46% but there was no statistically significant difference between them. An evaluation of a proliferative marker shown by a mean (±SD) of PCNA, was 34.63±23.87 and the mean (±SD) of AgNORs was 1.23±0.18. There was no significant difference between the PCNA and AgNORs index of both the histological types and the histological malignancy grades. However, a statistical difference of mean PCNA and AgNORs indices was noted in both c-erbB2 positive and c-erbB2 negative groups. The mean PCNA indices and AgNORs indices in c-erbB2 positive samples were 26.52±18.68 and 1.12±0.27 respectively, while the c-erbB2 negative ones were 39.43±26.24 and 1.28±0.19 respectively. In conclusion, c-erbB2 oncogene protein expression is considered to be an effective prognostic factor for adenocarcinoma subtypes of feline mammary tumors as it is in human and canine cases. However, integration of all the parameters (c-erbB2 oncogene protein, PCNA index, AgNORs index, histological types and clinical data) may achieve a more precise prognosis in feline, mammary tumor cases.

Multidrug Efflux Systems (Mes): A Mechanism Of Resistance To Multidrug In Bacteria, Rungtip Chuanchuen, Herbert P. Schweizer

The Thai Journal of Veterinary Medicine

Bacterial antibiotic resistance is a growing problem with a global dimension. While the mechanisms of resistance vary from agent to agent, most of them are agent specific, providing resistance to a single or a class of anitimicrobials. Multidrug efflux systems have currently emerged as a predominant cause of antimicrobial resistance across a broad spectrum of structurally - unrelated antimicrobials. Efflux-mediated resistance is promoted by the exclusion of agents from the systems, resulting in reduced intracellular concentration of drugs. MES occur in many Gram-positive and Gram-negative bacteria, including medically important pathogens, therefore they are of significant concern. Expression of the systems …

Eradicating Footrot From Western Australia - A Farmer's Guide, Department Of Agriculture, Western Australia Nov 2004

Eradicating Footrot From Western Australia - A Farmer's Guide, Department Of Agriculture, Western Australia

Agriculture reports

Virulent footrot can occur on any farm in the medium to high rainfall zone. Persons who regularly buy and sell sheep take a greater risk, but even properties with a closed breeding flock are at risk from stray sheep. People often associate footrot with properties managed by inefficient farmers. This is a false belief. Many good farmers have found the disease in their sheep, including high profile studs. Footrot can strike anywhere and often without warning. It is important to remember that once it is found; getting to know and understand the disease will help you to beat it. A …
