Pathological And Immunohistochemical Changes In The Liver Of Monocrotaline-Treated Rats, Şevket Soylu, Aydin Çevi̇k, Necati̇ Ti̇murkaan

Turkish Journal of Veterinary & Animal Sciences

Pathological and immunohistochemical changes in livers were investigated in monocrotaline-treated rats. Eighty adult-male Wistar rats were distributed in 5 groups, each containing 16 animals according to monocrotaline dose (Group I: 50 mg/kg, Group II: 100 mg/kg, Group III: 150 mg/kg, and Group IV: 200 mg/kg). The control group was administered with physiological saline. Half of the animals in each group were euthanized at the 18th hour while the remaining half at the 6th week postinoculation. At the end of the 18th hour, the most prominent lesion was hepatocytic apoptosis which was dose-dependent. Apoptotic cells were mostly located in periportal and …

The Thai Journal of Veterinary Medicine

The aim of this study was to determine the effectiveness of low-level laser therapy (LLLT) in the healing of experimentally created unicortical defect (UCD) of rat femurs. Twenty-four adult Wister rats were randomly divided into 2 groups: UCD and UCD+LLLT. The animals were subdivided into 3 groups (each group had 4 animals) and then they sacrificed at day 8, 15 and 22 for radiological, pathological and biochemical analysis. Bone healing was significantly different between the groups at day 15 and 22 (P < 0.05), while bone formation was significantly increased in the UCD+LLLT group at day 22 compared to the UCD group (P < 0.05). On histopathological examination, significant difference was found between the UCD and UCD+LLLT groups on the 22nd day (P < 0.05) while there was no difference on the 8th and 15th day. In the UCD group, the plasma Alkaline phosphatase activity decreased on the 15th and 22nd days, Calcium on the 15th day and Phosphorus on the 8th and 22nd days compared to the UCD+LLLT group. In addition, Glutathione levels, Plasma Catalase, Glutathione Peroxidase and Superoxide Dismutase activity significantly reduced in the UCD group compared with UCD+LLLT on the 8th, 15th and 22nd day (P < 0.05). In conclusion, LLLT applied at a dose of 904µm accelerates fracture healing in UCD of a rat’s femur. However, this effect shows an increase after the 22nd day of LLLT application.

A Review Of Rat Lungworm Infection And Recent Data On Its Definitive Hosts In Hawaii, Chris Niebuhr, Susan I. Jarvi, Shane R. Siers

United States Department of Agriculture Wildlife Services: Staff Publications

Rat lungworm (Angiostrongylus cantonensis) is a zoonotic nematode that causes rat lungworm disease (angiostrongyliasis), a potentially debilitating form of meningitis, in humans worldwide. The definitive hosts for rat lungworm are primarily members of the genus Rattus, with gastropods as intermediate hosts. This parasite has emerged as an important public health concern in the United States, especially in Hawaii, where the number of human cases has increased in the last decade. Here we discuss the current knowledge of the rat lungworm, including information on the life cycle and host species, as well as updates on known infection levels. Three species of …

Immunohistochemical Expression Of Secretory Proteins In Pneumonic Rat Lungs, Enver Beytut

Turkish Journal of Veterinary & Animal Sciences

The present study evaluated the expression of secretory proteins involving surfactant proteins (SP-A, SP-B, proSP-C), Clara cell secretory protein (CCSP), and thyroid transcription factor-I (TTF-I), together with lambda light chain IgG (λ-IgG), proliferating cell nuclear antigen (PCNA), and lymphocytic phenotypes (T and B cells) in the pneumonic rat lungs. The most prominent gross lesion was severe pulmonary abscession. The lungs showed severe parenchymal destruction and necrosis encapsulated by fibrous tissue. Immunostaining for SPs displayed evident hyperplasia of type II pneumocytes. Immunoreaction to SP-A and SP-B occurred strongly on the luminal surface of type II cells, and to proSP-C in the …

Turkish Journal of Veterinary & Animal Sciences

Cannabinoid receptor 2 (CB2) has a role in the pathology of some liver diseases. Cypermethrin (CYP) is a synthetic pyrethroid insecticide used commonly for the control of pests and vectors, and for protection of foodstuffs. In this study, the involvement of CB2 in CYP-induced liver damage in rats was investigated. CYP was applied to rats orally at a dose of 125 mg/kg bw per day for 14 days. CB2 agonist JWH-133 was administered by intraperitoneal injection at a dose of 3 mg/kg bw per day for the last 4 days of CYP toxicity. JWH-133 deteriorated the liver damage induced by …

Turkish Journal of Veterinary & Animal Sciences

Being multipotent progenitor cells, mesenchymal stem cells continue to attract attention as a promising tool for cell-based therapy and tissue engineering. However, research on the ultrastructure of these cells is rather scarce. This study was aimed at the investigation of the transmission electron microscopic ultrastructure and morphology of mesenchymal stem cells isolated from the stroma of rat umbilical cord using the explant culture method. At the end of the third passage, some of the cells isolated from the stroma of the umbilical cord were harvested for electron microscopic examination. The remaining cells were induced for osteogenic, chondrogenic, and adipogenic differentiation. …

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, …

The Thai Journal of Veterinary Medicine

GnRH is not only a primary regulator of gonadal function but also a possible factor which affects other pituitary cells out of gonadotrophs. Recently, it has been reported that GnRH might induce the release of GH, but the effects on GH and other pituitary hormones of GnRH still remained controversial. In this study, OHE was performed in 30-week-old female Sprague Dawley rats as experimental groups. Intact female rats were taken as control group. GnRH stimulation at different weeks (20, 24, and 30) after OHE was examined in all rats. Evaluation of the circulating GH, IGF-I, ACTH, TSH concentrations at different …
