Turkish Journal of Veterinary & Animal Sciences

The present paper studied the effect of screened wheat (SW) levels and a multienzyme diet on Japanese quail performance, intestinal performance, and microbial population. A total of 480 unsexed 10-day-old quail chicks were assigned to a multienzyme diet (0 or 0.5 g/kg) and SW (0%, 5%, 10%, or 15%) in a 2 x 4 factorial arrangement of treatments with 4 replications and 15 quails in each in a completely randomized design. No differences were observed in performance between diets at 10 to 36 days of age. Increases in dietary SW levels decreased villus height, villus width, villus surface, and height:crypt …

Seaweeds contains different types of polysaccharides with high abilities. The aim of this study was to determine the potential of fucoidan polysaccharides for wound-healing properties. Fucoidans of two species of Padina (P. tetrastromatica and P. boergesenii), collected from the Persian Gulf northern coastal area, were extracted and analyzed using high-performance anion-exchange chromatography. Purified fucoidans were used to prepare a 2% topical ointment. Under aseptic conditions, two identical paravertebral full-thickness skin wounds (either by burn or excision) were made in 40 anesthetized male rats allocated into 4 groups. Either fucoidan ointments or the vehicle (ointment base) were applied to rats' wounds …

Effects Of Ketamine On Monoamine Neurotransmittersand Gaba In Embryonic Neurocytes From Fetal Rat, Xinran Li, Mo Liu, Yue Li, Cen Guo, Lina Li, Yanan Li, Yuxin Wang, Yiming Zhang, Li Gao

Turkish Journal of Veterinary & Animal Sciences

The effect of ketamine, a drug commonly used as an anesthetic, on monoaminergic neurotransmitters and GABA in neurocytes from fetal rats has not yet been elucidated. We thus decided to investigate these effects by first evaluating ketamine levels in the cerebrospinal fluid by high-performance liquid chromatography. We thus determined the concentrations of GABA, DA, NE, 5-HT, and 5-HIAA following the addition of four different concentrations of ketamine at day 7 of nerve cell culture. GABA, 5-HT, and 5-HIAA levels were increased after an initial decrease: they showed the lowest levels at 10-15 min and the highest peaks at 45-90 min, …

Potentials Of Ivabradine To Improve Cardiac Function In Dogs With Naturally Occurring, Asymptomatic Degenerative Mitral Valve Disease, Prapawadee Pirintr

Chulalongkorn University Theses and Dissertations (Chula ETD)

The main hypothesis of the present study is that ivabradine (1.0 mg/kg, orally, twice daily) can reduce heart rate (HR), myocardial oxygen consumption (MVO2) and improve cardiac function in dogs with degenerative mitral valve disease (DMVD) partly due to a reduction of cardiomyocyte apoptosis. In order to test the hypothesis, this study was divided into three parts. The first part aimed to determine the appropriate single oral dose of ivabradine for reduction of HR and MVO2 as assessed by rate-pressure product (RPP= HR x systolic blood pressure). Once the appropriate dose was achieved, the second part was conducted to investigate …

Effects Of Short-Term Growth Hormone Administration On Plasma Leptin Levels In Normal And Diet-Induced Obesity Rats, Sutharinee Likitnukul

Chulalongkorn University Theses and Dissertations (Chula ETD)

Obesity has related to the alteration of hormonal profiles, i.e. growth hormone (GH), insulin and leptin. Because of the pleiotropic mechanisms of GH, it plays important roles both in the pathophysiological mechanisms and the therapeutic hormonal supplementation, which probably affected plasma leptin. The present research aimed firstly to demonstrate the effect of short-term GH administration on plasma leptin in 3 conditions; basal, meal-induced and fasting condition, from the rats with different adipose tissue mass. Secondly, to investigate short-term effect of GH on insulin sensitivity and body adiposity in control, diet resistant (DR) and diet-induced obesity (DIO) rats. In this regard, …

Chulalongkorn University Theses and Dissertations (Chula ETD)

Leaky gut characterized as decreased transepithelial electrical resistance and increased paracellular permeability to macromolecules is associated with several fatal diseases including sepsis. Pro-inflammatory cytokine IL-1β is a critical mediator of underlying mechanism through activation of myosin light chain kinase pathway. Blocking the inducible phosphorylated myosin light chain (p-MLC) indicates the successful treatment. Xanthones predominantly found in mangosteen (Garcinia mangostana) has been indicated as a potent anti-inflammatory action. Hydroxyxanthones (HDX), the major natural xanthones, have been recently synthesized in various forms. This study aimed to examine and screen the action of various forms of synthetic HDXs, in preventing the increased paracellular …

Chulalongkorn University Theses and Dissertations (Chula ETD)

Multicentric lymphoma is the most common hematopoietic tumors in dogs. Both B- or T-lymphocyte clones can originate to lymphoma. A gold standard method to differentiate each lymphocyte lineage is immunohistochemistry (IHC) by detecting specific proteins of B and T cell. A protein marker for T and B cells is CD3 and CD79a, respectively. However, another pan pre B-cell marker is Pax5 or B-cell specific activator protein. It is more specific and sensitive than CD79a because it expresses only in B-cell lymphoma cases. The first purpose of this research was to 1) determine Pax5 expression in canine lymphomas by IHC and …
