Doctor of Philosophy . Morphological characteristics of the inner medullary zone in the kidneys in Brattleboro and Wistar rats were studied during blockade of prostaglandin synthesis. Reece WO. The results demonstrated that Wistar rats were the most susceptible strain to CIA followed by Wistar Furth rats, with Sprague Dawley rats being the least susceptible. 26. Department of Nutritional Sciences University of Toronto . The spermatozoa characteristics of Wistar rats in Groups A (control), B treated with chloramphenicol for 20 days and C treated with chloramphenicol for 25 days are as presented in Table I. Motility in the control experiment (Group A) was 89.0 ± 2.45%, which is higher than Group B (72.0 ± 3.74%) and Group C (66.0 ± 2.45%). 2020 Jul;48(5):649-655. doi: 10.1177/0192623320922849. 2011 . Following primary and booster immunization, female Wistar rats developed severe arthritis, with an incidence of >83% and low variability in clinical signs. Nikolskaia, K., Eshchenko, O., & Shpinkova, V. (1997). Spontaneous Rat Nonthymic T Cell Lymphoma 329 Table 2. [The characteristics of exploratory behavior in Wistar rats in a permanent inhomogeneous magnetic field]. In: Diagnostic and therapeutic techniques in animal reproduction. However, the gastric microbiota of GK and Wistar rats are still unclear. the rat. Materials and Methods. Monoclonal Antibodies Against 0x7 W3/13 OX8 W3/25 OX4 0x12 Organ The specific objectives of the present study were accordingly as follow: (1) to establish an experimental model of TBBPA particle inhalation exposure using Wistar rats; (2) to investigate the excretion characteristics of inhaled TBBPA dry-powder following mouth and nose inhalation exposure; and (3) to investigate the concentration of TBBPA in serum following inhalation exposure over a 14-d … A total of 374 mammary tumors and 106 hyperplastic lesions were identified in female rats, five tumors were found in male rats. Thus, the findings in the female Wistar rat CIA model closely resemble the disease characteristics of human RA. (Smaller thin-tailed rodents are just as often indiscriminately referred to as mice.) Immunohistochemical characteristics of lymphocytes from formalin-fixed sections of bone marrow and lym- phoid tissues of normal Wistar rats. However, toxicity of nanoparticles is a subject of continued controversy, thus necessitating further studies in this direction. Objectives . Zemjanis R. Collection and evaluation of semen. Ulceration and necrosis of the over- lying skin was commonly observed with rap- idly growing masses. The best-known Rattus species are the black rat (R. rattus) and the brown rat (R. norvegicus).The group is generally known as the Old World rats or true rats and originated in Asia.Rats are bigger than most Old World mice, which are their relatives, but seldom weigh over 500 grams (1.1 lb) in the wild.. Taxonomy of Rattus At that time, the behavior of each naive rat was observed for two 3-minute periods separated by an interval of 24 h (Day). He later established Wistar Institute in Philadelphia that will have a major role in the development of the rat as an important laboratory animal similar to the impact the Jackson laboratory had on the development of the laboratory mouse. Gut microbiota remains a prominent source for a diverse range of potential probiotics. Adult male Wistar rats were exposed to repeated doses of NGO for 15 days and 30 days. Background: The Goto-Kakizaki (GK) rat, developed from repeated inbreeding of glucose-intolerant Wistar rats, has been widely used to explore the development of spontaneous type-2 diabetes mellitus (T2DM). Gonadosomatic index and spermatozoa morphological characteristics of male Wistar rats treated with graded concentration of Aloe vera gel. Sixteen lactic acid bacteria (LAB), from rectal swab of Wistar rats, were subjected to evaluation of probiotic properties. The open field test (OFT) was carried out on Wistar and Sprague-Dawley rats between the ages of 3 to 20 weeks. Immunohistochemical Characteristics of Thymomas and Hyperplastic Lesions in Wistar Hannover Rats Toxicol Pathol. Background: Chronic nonbacterial prostatitis associated with lower urinary tract symptoms (LUTS) is a prevalent condition in men. Silver nanoparticles have found wider and increasing biomedical applications due to their broad antimicrobial characteristics. [Article in Russian] Nikol'skaia KA, Eshchenko OV, Shpin'kova VN. Sandra Alicia Reza López . [The characteristics of exploratory behavior in Wistar rats in a permanent inhomogeneous magnetic field]. Characteristics of Metabolic Syndrome in Wistar Rat Dams and their Offspring . 2nd Ed. Asano Y. 27. Quantitative cytochemical assay showed that single injection of delta sleep-inducing peptide increased monoamine oxidase activity (substrates: serotonin and tryptamine) in the caudate and accumbens nuclei and glutamate dehydrogenase activity in the hippocampus of stress-resistant Wistar rats chronically treated with L-DOPA. First, two adult rat groups (aged 90 d) were studied: a control group (C1; n 6) received regular rodent chow (Labina, Purina) and a fructose group (F1; n 6) was fed on regular rodent chow. Baltimore, MD: William and Wilkins Company, 1970:242. All these tumors were examined microscopically, and the morpho- logical characteristic described (Table I). Male Wistar Rats (n = 48, initial body weight: 115.30 ± 1.73 g) were allocated into 4 groups (n = 12/group) and received one of the following diets: Normal sodium normal fat (NSNF), normal sodium high fat (NSHF), high sodium normal fat (HSNF), high sodium high fat (HSHF) diet for 12 weeks. Species and description. Body weight (BW) and food intake (FI) were measured weekly. In this context, the current study explored the rectal region of experimental Wistar rat for the isolation of potent probiotic. Here, we evaluated the physicochemical characteristics as well as acute and subacute toxicity of the CNSO in rats. Int J Anim Vet Adv 2011;3(2):47–53. of rats in the USA. In search of an adequate model for the human metabolic syndrome, the metabolic characteristics of Wistar rats were analysed after being submitted to different protocols of high fructose ingestion. •The Wistar bloodline has contributed more strains of rats than any other line. The absence of a diuretic effect of prostaglandins on the kidneys was accompanied by structural changes in the transepithelial and interstitial barriers for an osmotic flow of water. Characteristics of Open Field Behavior of Wistar and Sprague-Dawley Rats Yuzo ASANO Safety Research Laboratory, Tanabe Seiyaku Co., Ltd., Kashima 3-16-89, Yodogawa-ku, Osaka 532, Japan (Received 31 January 1986/Accepted 2 May 1986) The open field test (OFT) was carried out on Wistar and Sprague-Dawley rats between the ages of 3 to 20 weeks. This study investigated the biochemical effects of silver nanoparticles in Wistar rats. Rat, (genus Rattus), the term generally and indiscriminately applied to numerous members of several rodent families having bodies longer than about 12 cm, or 5 inches. 2Department of Veterinary Surgery and … The effect of oleanolic acid on sperm motion characteristics and fertility of male Wistar rats M.
