Qianlie Tongqiao Capsule (QTC) is clinically confirmed to be efficacious and safe in treating lower urinary tract syndromes and bladder dysfunction that are induced by benign prostatic hyperplasia (BPH). However, the functional mechanisms of QTC remain unclear. We aim to investigate the effects of
Histopathological characteristics of urinary bladder tumors induced in Syrian golden hamsters by 3,2'-dimethyl-4-aminobiphenyl (DMAB) were analyzed. DMAB was subcutaneously injected in corn oil at a concentration of 100 mg/kg once a week for 20 weeks and ethinyl estradiol (EE) was administered in
The effects of castration and testosterone on the autonomic receptor density and contractility in the urinary bladder smooth muscle of male rabbits were compared to untreated animals. Four groups of rabbits were studied over a similar time span with Group 1 animals serving as the untreated controls.
Cholecystokinin (CCK) release and gall bladder emptying in response to a fatty meal are completely abolished in coeliac disease. To determine the effect of lipid digestion on CCK release and gall bladder motility, six patients with untreated coeliac disease and a flat jejunal mucosa were studied on
OBJECTIVE
To assess gene expressions of cyclooxygenase-1 and -2 in oral, glandular gastric, and urinary bladder mucosae and determine the effect of oral administration of phenylbutazone on those gene expressions in horses.
METHODS
12 healthy horses.
METHODS
Horses were allocated to receive
Thirteen-week toxicity studies of the flame retardant 2,2-bis(bromomethyl)-1,3-propanediol (BMP; dibromoneopentyl glycol; FR-1138; CAS No. 329690-0) were conducted in male and female F344/N rats and B6C3F1 mice. The chemical was administered by oral gavage in corn oil 5 days per week for 13 weeks to
The dried stigmata from Zea mays L. are used traditionally for the treatment of uncomplicated urinary tract infections. A recent screening has indicated that hydroalcoholic extract of the herbal material inhibits the adhesion of uropathogenic Escherichia coli (UPEC) to T24 bladder cells. For
The efficacy of a wide-spectrum organ carcinogenesis model for detection of modification potential of exogenous agents was investigated in F344 male rats. Groups of animals were sequentially injected with N-bis(2-hydroxypropyl)nitrosamine (1000 mg/kg body weight, i.p., in saline, twice in week 1),
Telone II (technical grade, 1,3-dichloropropene), a soil fumigant, was evaluated in chronic toxicology/carcinogenicity studies using Fischer-344 (F344) rats and B6C3F1 mice of both sexes. Doses administered were 0, 25, or 50 mg/kg to rats and 0, 50, or 100 mg/kg to mice. Telone II was given in corn
A bioassay of technical-grade m-cresidine for possible carcinogenicity was conducted using Fischer 344 rats and B6C3F1 mice. m-Cresidine in corn oil was administered by gavage five days a weeks at either of two dosages, to groups of 50 male and 49 or 50 female animals of each species. The dosages
Allylisothiocyanate (AITC) has been evaluated for its ability to initiate unscheduled DNA synthesis (UDS) in the livers of male rats in vivo. Specific Pathogen Free outbred albino Hsd/Ola Sprague-Dawley rats were exposed by oral gavage to 37.5 or 125 mg/kg AITC in corn oil and hepatocytes assessed
Toxicology and carcinogenesis studies of Telone II(R) (a soil fumigant containing approximately 89% cis- and trans-1,3-dichloropropene, 2.5% 1,2-dichloropropane, 1.5% of a trichloropropene isomer, and 1.0% epichlorohydrin) were conducted by administering the commercial-grade formulation in corn oil
Benign prostatic hyperplasia, prostate cancer, and changes in the ratio of circulating testosterone and estradiol often occur concurrently in aging men and can lead to lower urinary tract (LUT) dysfunction. To explore the possibility of a fetal basis for the development of LUT dysfunction in
A 2-year carcinogenesis bioassay of food-grade allyl isothiocyanate (greater than 93% purity), a flavoring agent, was conducted by administering 12 or 25 mg/kg allyl isothiocyanate in corn oil five times per week by gavage to groups of 50 F344/N rats and 50 B6C3F1 mice of each sex for 103 weeks.
Studies were conducted to compare outcomes when four chemicals were evaluated under typical NTP bioassay conditions as well as under protocols employing dietary restriction. Specific experiments were designed to evaluate the effect of diet restriction on the sensitivity of the bioassay toward
