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. Background: Chronic nonbacterial prostatitis associated with lower urinary tract symptoms (LUTS) is a prevalent condition in men. 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). 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. Thus, the findings in the female Wistar rat CIA model closely resemble the disease characteristics of human RA. Characteristics of Metabolic Syndrome in Wistar Rat Dams and their Offspring . In this context, the current study explored the rectal region of experimental Wistar rat for the isolation of potent probiotic. Background . Gut microbiota remains a prominent source for a diverse range of potential probiotics. Immunohistochemical characteristics of lymphocytes from formalin-fixed sections of bone marrow and lym- phoid tissues of normal Wistar rats. Ulceration and necrosis of the over- lying skin was commonly observed with rap- idly growing masses. This study investigated the biochemical effects of silver nanoparticles in Wistar rats. One potential pathophysiological factor is change in sex hormone, testosterone and estrogen, balance. Body weight (BW) and food intake (FI) were measured weekly.

Epub 2020 Jun … 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 … Morphological characteristics of the inner medullary zone in the kidneys in Brattleboro and Wistar rats were studied during blockade of prostaglandin synthesis. Spontaneous Rat Nonthymic T Cell Lymphoma 329 Table 2. Asano Y. Enzyme activities in the sensorimotor cortex did not change. 2Department of Veterinary Surgery and … 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. Here, we evaluated the physicochemical characteristics as well as acute and subacute toxicity of the CNSO in rats. 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 Objectives . Materials and Methods. Silver nanoparticles have found wider and increasing biomedical applications due to their broad antimicrobial characteristics. A total of 374 mammary tumors and 106 hyperplastic lesions were identified in female rats, five tumors were found in male rats. Spermatozoa morphology and characteristics of male wistar rats administered with ethanolic extract of Lagenaria Breviflora Roberts Adebowale Bernard Saba1*, Olayinka Ayotunde Oridupa1, Matthew Olugbenga Oyeyemi 2 and Oluwaseun Dapo Osanyigbe1 1Department of Veterinary Physiology, Biochemistry and Pharmacology, University of Ibadan, Nigeria. 2011 . All these tumors were examined microscopically, and the morpho- logical characteristic described (Table I). Nikolskaia, K., Eshchenko, O., & Shpinkova, V. (1997). However, toxicity of nanoparticles is a subject of continued controversy, thus necessitating further studies in this direction. Adult male Wistar rats were exposed to repeated doses of NGO for 15 days and 30 days. 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 effect of oleanolic acid on sperm motion characteristics and fertility of male Wistar rats M. C.

Doctor of Philosophy . In: Diagnostic and therapeutic techniques in animal reproduction. Characterization a model of prostatic diseases and obstructive voiding induced by sex hormone imbalance in the Wistar and Noble rats. [The characteristics of exploratory behavior in Wistar rats in a permanent inhomogeneous magnetic field]. Sixteen lactic acid bacteria (LAB), from rectal swab of Wistar rats, were subjected to evaluation of probiotic properties. Reece WO. Zemjanis R. Collection and evaluation of semen. The OFT scores varied depending on the day and the age. Following primary and booster immunization, female Wistar rats developed severe arthritis, with an incidence of >83% and low variability in clinical signs. [The characteristics of exploratory behavior in Wistar rats in a permanent inhomogeneous magnetic field]. At that time, the behavior of each naive rat was observed for two 3-minute periods separated by an interval of 24 h (Day). of rats in the USA. 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. 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. 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%). However, the gastric microbiota of GK and Wistar rats are still unclear. 2nd Ed.

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. Physicochemical characteristics of CNSO demonstrated high percentage oil yield, low saponification value, elevated acid and free fatty acid … Characteristics of open field behavior of Wistar and Sprague-Dawley rats. Department of Nutritional Sciences University of Toronto . 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. 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.
