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.

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

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

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 …

Physiological Reactions Of Poultry To Heat Stress And Methods To Reduce Its Effects On Poultry Production, Narongsak Chaiyabutr
Physiological Reactions Of Poultry To Heat Stress And Methods To Reduce Its Effects On Poultry Production, Narongsak Chaiyabutr
The Thai Journal of Veterinary Medicine
Thermal environment is regarded as the prime factor governing the production because, both the feed consumption and heat production are related closely to the thermal environment. Therefore, heat stress is caused by a combination of environmental and animal factors that result in reduced performance as the animal attempts to cool itself. In this review, the physiological reactions of bodily functions during heat exposure in poultry are described. Thermal panting, the marked response of poultry to heat stress, is compensatory behavior to permit a high rate of evaporative cooling from the respiratory tract. Cardiorespiratory responses to thermal stress show different patterns …

The Thai Journal of Veterinary Medicine
The objective of this study was to estimate the glomerular filtration rates of normal dogs using the clearance of endogenous creatinine, and comparing it to the clearance of exogenous creatinine. Nine healthy dogs, of both sexes, were used in this study. The results showed a significant relationship, with a correlation coefficient = 0.714 (p<0.05). The regression line was an endogenous creatinine clearance = (-0.803 + 0.677) x exogenous creatinine clearance. The use of endogenous creatinine clearance is a simple and convenient method without the need to administer any substances and can be used to evaluate renal function in clinical practice.

The Function Of The Oviduct In Relation To Sperm Transport And Capacitation In Swine, Paisan Tienthai
The Function Of The Oviduct In Relation To Sperm Transport And Capacitation In Swine, Paisan Tienthai
The Thai Journal of Veterinary Medicine
In the pig, sperm transport is regulated, to facilitate normal fertilization of the ovulated oocytes, by the oviduct which contains a particular segment, the sperm reservoir. The main function of the sperm reservoir is to ensure that stored spermatozoa have maintained viability and fertilizing capacity. The process of sperm capacitation is delayed in the sperm reservoir, during the lengthy pre-ovulatory estrus by interactions between the spermatozoa, the oviduct epithelium and secretion products. Sperm capacitation seems to be facilitated by the tubal fluid in the upper segment of the oviduct releasing sperm from the reservoir in relation to the time of …
