An inbred strain of fawn hooded rats with a congenital platelet defect shows a marked bleeding tendency with prolonged bleeding time. This haemorrhagic disorder has been exclusively related to a deficiency of nucleotides in platelet dense granules. When tested in cell electrophoresis platelets from
Understanding demographic parameters such as survival is important for scientifically sound wildlife management. Survival can vary by region, sex, age-class, habitat, and other factors. White-tailed deer fawn survival is highly variable across the species' range. While recent studies have
The fawn-hooded (FH) rat develops hypertension spontaneously. Systolic blood pressure is already elevated at 5 weeks of age, increases with age, and the final range is 180-240 mmHg at the age of 1 year. Concomitantly with the rise in blood pressure proteinuria occurs and increases with age.
The Fawn hooded (FH) rat is commonly used in biomedical research. It is widely acknowledged that the FH rat has a bleeding disorder; leading to abundant bleedings. Although this bleeding disorder is investigated to model the storage pool defect; its impact on commonly performed invasive laboratory
Release of platelet dense granule contents occurs in response to vascular injury, playing an important role in platelet aggregation and primary hemostasis. Abnormalities of the platelet dense granules results in a bleeding disorder of variable severity termed "storage pool defect" (SPD). We have
A large colony of fawn-hooded (FH) rats, comprising five original families and six generations of their progeny, was developed for genetic and comparative studies of their bleeding tendency. The characteristics of the bleeding diathesis in these rats are similar to those originally reported in
A 3-month-old fawn from a group of 12 captive white-tailed deer (Odocoileus virginianus) displaying cutaneous lesions was presented to the Mississippi Veterinary Research & Diagnostic Laboratory for necropsy. Postmortem examination identified multiple discrete, round, alopecic, flat, proliferative
Fawn hooded rats (FHR), a strain of rat with a hereditary bleeding tendency due to a genetic defect in platelet aggregation, have recently been found to develop pulmonary hypertension. However, whether the pulmonary hypertension in FHR has a genetic basis or simply reflects the influence of
The Fawn-Hooded strain of rats exhibits a hemorrhagic disorder, known as platelet storage pool deficiency. In addition to the platelet dysfunction, there is an altered response to certain serotonin drugs. To assess the characteristics of the binding to 5-HT1A and 5-HT2 receptors in this strain,
During the 1990s, pronghorn (Antilocapra americana) populations declined in Arizona, USA. To investigate potential causes of decline, we collected blood samples from hunter-harvested male pronghorn from 2001 to 2003 on four Arizona sites. Sera were tested for antibody to parainfluenza virus type 3
The Fawn-Hooded (FH) genetic animal model of depression continues to be of interest because the FH model has limited biochemical and immune function. The FH animal has an inherited trait, platelet storage pool deficiency (PSPD), an hemorrhagic disorder that is also a component of Chediak-Higashi
A 73-d-old white-tailed deer (Odocoileus virginianus) fawn was diagnosed at necropsy with a ventral abdominal cellulitis secondary to urine after preputial swelling, urethral obstruction and hemorrhage, and focal urethral rupture. During the acute antemortem disease phase, the urinary obstruction
Fawn-hooded rats have a hemorrhagic disorder known as platelet storage pool deficiency. Parent stocks of Fawn-hooded, Long-Evans, and Wistar (DAB) rats and the progeny of their reciprocal crosses were studied for coat color and percentage 14C-serotonin uptake and secretion by blood platelets.
Fawn-hooded (FH) rats possess a hereditary bleeding diathesis and platelet function defect, which is presumably the result of a storage pool deficiency. In this study, we have investigated the prostaglandin synthesis capacity of platelets and aorta from FH rats as compared to Sprague Dawley (SD)
Hermansky-Pudlak syndrome (HPS) is a group of rare, recessive disorders in which oculocutaneous albinism, progressive pulmonary fibrosis, bleeding diathesis, and other abnormalities result from defective biogenesis of multiple cytoplasmic organelles. Seven different HPS genes are known in humans; in
