BACKGROUND Because of the significance of androgens and estrogens in prenatal and postanatal differentiation of the testis and excurrent ducts, it is important to understand the developmental pattern of androgen receptor (AR) and estrogen receptor (ER) in these organs. METHODS Tissues from 1-23-week-old goats were fixed in 4% paraformaldehyde and embedded(More)
BACKGROUND Since androgens and/or estrogens must bind with specific receptors in order to elicit a response at the target organ(s), it is important to understand factors that regulate expression of androgen receptors (AR) and estrogen receptors (ER). Hence, the objective of the study is to determine the relative significance between circulating androgen(More)
Caprine efferent ductule epithelium contains ciliated and nonciliated cells. The latter cells are divided into three types: type II cells contain PAS-positive granules, type III cells contain PAS-negative vacuoles, and type I cells lack both granules and vacuoles (Goyal and Williams, Anat. Rec. 220:58-67). The objectives of this study are i) to determine(More)
The histochemical localization of alkaline phosphatase (ALP) and acid phosphatase (ACP) was determined in regions I to VI of the epididymis in mature intact, orchidectomized, and orchidectomized testosterone-treated bulls. The intensity of ALP activity was essentially the same in all regions; however, its localization varied depending upon the region.(More)

Nicotine poisoning is a rarely reported toxicosis. The clinical signs and symptoms are complex and are mostly of central nervous system derangement. In addition, animals may have hypersalivation, vomiting, diarrhea, tachycardia, tachypnea, hypertension and hyperthermia. Some animals are presented in total collapse with slow and shallow respirations,(More)
OBJECTIVE The completion of a bladder diary is routinely undertaken as part of the initial assessment of women presenting with lower urinary tract symptoms. Anecdotally some women find it a nuisance to fill in a fluid volume chart. The QQ10 is a questionnaire which has been developed to evaluate the use of other questionnaires or investigations. This study(More)
The serum concentration-time data for ticarcillin (TICAR) and clavulanic acid (CLA) following intravenous and intramuscular administration of Timentin (TICAR, 50 mg/kg with CLA, 1.7 mg/kg) indicated that absorption of CLA following intramuscular injection and its overall elimination from the body was faster than that of TICAR. This is supported by(More)
BACKGROUND Massachusetts (MA) instituted a moratorium on ambulance diversion ("No Diversion") on January 1, 2009. STUDY OBJECTIVES Determine whether No Diversion was associated with changes in Emergency Department (ED) throughput measures. DESIGN Comparison of three 3-month periods. Period 1: 1 year prior (January-March 2008); Period 2: 3 months prior(More)
Observations from extratesticular rete-ligated, mature goats indicated that epithelial morphology in the tail of the epididymis can be maintained without any input from testicular fluid (Goyal et al., Acta Anat., 1994;150: 127-135). Hence, the objective of this study was to determine whether the tail of the epididymis and/or other regions of the male(More)
