The Causes of Canine Myocarditis and Myocardial Fibrosis Are Elusive by Targeted Molecular Testing: Retrospective Analysis and Literature Review.

Myocarditis can cause death or permanent heart damage. As epidemiologic and etiopathologic data for canine myocarditis are lacking, we performed a retrospective study using nucleic acid extracted from archived (2007 to 2015) tissues from myocarditis cases and control dogs without myocardial lesions. Heart tissue from pediatric/juvenile and adult dogs was tested with a comprehensive panel of conventional and real-time polymerase chain reaction (PCR) assays targeting recognized agents of canine myocarditis based on a literature review and informed by the comparative epidemiology of human myocarditis.

Hair repigmentation associated with thalidomide use for the treatment of multiple myeloma.

A 75-year-old woman diagnosed with multiple myeloma in 2007 began treatment with monthly melphalan and prednisone for a total of 9 cycles in combination with thalidomide in 2009. The patient subsequently continued on thalidomide for long-term maintenance therapy. 3 years following initiation of thalidomide, the patient mentioned to her oncologist that her hair had become darker over the years.

Transforming the context of care through shared leadership and partnership: an international CNO perspective.

This article explores the concept of the chief nursing officer's (CNO's) role in explaining and supporting the context of nursing for nurse administrator education and training in future decades. The role of the nurse leader in an organized setting is to provide the context for nursing as a discipline and well as the resource allocation for the content of nursing. Little has been written or researched about the role in support of the context for nursing.

Dietary supplementation with monosodium glutamate is safe and improves growth performance in postweaning pigs.

Dietary intake of glutamate by postweaning pigs is markedly reduced due to low feed consumption. This study was conducted to determine the safety and efficacy of dietary supplementation with monosodium glutamate (MSG) in postweaning pigs. Piglets were weaned at 21 days of age to a corn and soybean meal-based diet supplemented with 0, 0.

Cultural attitudes and beliefs about pain.

Patients and health professionals bring their own cultural attitudes to the communication and interpretation of the patient's pain experience. In this interaction, it is the health professional's knowledge and attitudes that dominate the response to the patient's experience of pain. In Saudi Arabia, a multicultural foreign and local health care team is challenged to understand the cultural beliefs and attitudes toward pain of both patients and team members.

Repetitive propofol administration in dogs and cats.

A bolus of propofol was administered to 10 dogs (6 mg/kg intravenously [IV]) and 10 cats (10 mg/kg IV) on three consecutive days. The occurrence of apnea, heart and respiratory rates, blood pressure, time to movement, and changes in a complete blood count and biochemical profile were recorded. Apnea was not seen in the dogs but was seen in three cats.

Quality of tissue specimens obtained endoscopically from the duodenum of dogs and cats.

Objective: To evaluate quality of duodenal tissue specimens obtained endoscopically from dogs and cats and submitted to 1 of 2 diagnostic laboratories for evaluation.

Design: Case series.

Sample Population: Slides from 50 consecutive canine and 50 consecutive feline endoscopically obtained duodenal tissue specimens submitted to laboratory 1 and 49 consecutive canine and 46 consecutive feline specimens submitted to laboratory 2.

Ultrastructural localization of unique neurosecretory granules in the corpora cardiaca of the stable fly, Stomoxys calcitrans, and the tsetse fly, Glossina morsitans.

Ultrastructural analysis of the corpora cardiaca of the stable fly, Stomoxys calcitrans, and the tsetse fly, Glossina morsitans, revealed the presence of elementary neurosecretory granules (ENG) unique to the intrinsic neurosecretory cells (INC) of these species. In addition to electron-dense spheres, the INC of the corpus species. In addition to electron-dense spheres, the INC of the corpus cardiacum of the stable fly contain electrondense angular granules, either square or rectangular in shape, while the INC of the tsetse fly contain electron-dense spindle-shaped ENG.

Mammary adenocarcinoma in four mares.

Mammary gland adenocarcinoma in 4 horses was characterized by firm swelling of the gland and serosanguineous discharge from the teat orifice. Two of the mares had ulcerative lesions of the mammary gland. Palpation of the affected gland typically elicited signs of pain.

Behavioral and histopathologic effects following intrathecal administration of butorphanol, sufentanil, and nalbuphine in sheep.

A large number of opioids and nonopioids have been administered epidurally and intrathecally in the hope of providing segmental analgesia without serious adverse effects. However, neurotoxicity data are generally unavailable for many of these drugs. The present study evaluated the behavioral, motor, electroencephalographic, and histopathologic changes following intrathecal injection of large and small doses of butorphanol, sufentanil, and nalbuphine in sheep.

Cloprostenol induced luteal regression in the beef cow. II. Histological evaluation of corpora lutea and correlation with luteal progesterone.

Forty-two cycling, multiparous beef cows (percentage-Brahman) were injected twice at 11-d intervals with 500mug Cloprostenol (a prostaglandin F(2alpha) analog) to induce luteolysis. Cows were randomly assigned for ovariectomy at 12 hr intervals from 0 to 72 hr post-injection. Corpora lutea were excised and one-half of the corpus luteum was stored in phosphate-buffered formalin until mounting and staining with hematoxylin and eosin.

A chick model for impaired renal function.

To evaluate some of the metabolic consequences of impaired renal function (IRF) in the chick, a surgical method to induce IRF was developed that involves the destruction of approximately 85% of the renal mass by ureteral ligation. It is relatively simple with minimal time and labor required, produces low mortality, requires little specialized postoperative care, and is readily reproducible. Three-week-old control, sham-operated, and IRF chicks were bled by cardiac puncture and biochemical measurements were made on serum samples.

The influence of multiple liver biopsies on hematologic and serum biochemical values of sheep.

A rapid, simple liver biopsy technique for sheep was developed to obtain in situ liver samples for evaluation of histological tissue, enzyme assay, and ultrastructural changes that might occur during toxicological testing. The study was designed because repeated biopsies in the same individual could induce bias in hematologic, histological or serum biochemical parameters caused by the trauma of the biopsy procedure. In Experiment I, sheep were divided into a biopsied group (B), sham-operated group (SO), and a nonsurgical, untreated control group (C).

The comparative biologic and toxic potencies of polychlorinated biphenyls and polybrominated biphenyls.

Aroclor 1254 and fireMaster BP-6, two commercial polychlorinated biphenyl (PCB) and polybrominated biphenyl (PBB) preparations, exhibit comparable biologic and toxic effects. In the present study the commercial PBB was more active than Aroclor 1254 in causing thymic atrophy in male Wistar rats. However, a direct comparison of the relative effects of bromine vs chlorine substituents is not possible with the commercial PBB and PCB mixtures due to their complex congeneric composition.

Phototoxic effect of Thamnosma texana (Dutchman's breeches) in sheep.

Oral exposure of sheep to the airdried, aerial portions of Thamnosma texana (Dutchman's breeches) resulted in severe photosensitization. Sheep fed the plant at 9 or 12 g/kg of body weight/day and held in direct sunlight exhibited signs of phototoxicosis within 24 to 48 hours. The clinical signs manifested were increased body temperature; photophobia; edema of the muzzle, ears, and vulva; keratoconjunctivitis with edema of the cornea; and exudative dermatitis of the skin of the ears, muzzle, and vulva.

Toxicity of 3,3',4,4'- and 2,2',5,5'-tetrabromobiphenyl: correlation of activity with aryl hydrocarbon hydroxylase induction and lack of protection by antioxidants.

3,3',4,4'-Tetrabromobiphenyl is a minor component of commercial polybrominated biphenyl (PBB) mixture fireMaster BP-6 and is a potent inducer of aryl hydrocarbon hydroxylase (AHH). A single ip dose of 3,3',4,4'-tetrabromobiphenyl (150 mumol/kg) caused significant reduction in the growth rate in the immature male Wistar rat, as well as pale enlarged livers and marked reduction in thymus size. Under light microscopy, hepatocytes were enlarged and vacuolated.

Acute toxicity of tri-ortho-cresyl phosphate in sheep and swine.

Tri-ortho-cresyl phosphate (TOCP) was given orally or by subcutaneous (SC) injection to sheep and swine. Sheep given oral doses of 100, 200, or 400 mg of TOCP/kg of body weight developed an acute intoxication characterized by diarrhea dehydration, metabolic acidosis, and death within 6 days. Daily SC injections of TOCP in sheep caused either death or delayed neurotoxicosis depending upon the dosage.

Cytoplasmic bridges between mammalian red blood cells: an early indication of kidney dysfunction.

Scanning electron microscopy, correlated with hematological and clinical biochemical observations demonstrated that cytoplasmic bridges develop between the erythrocytes of sheep in which varying degrees of acute renal dysfunction has been produced by treatment with a toxin (uranyl nitrate) or by surgical ligation of a renal artery or ureter. The presence of cytoplasmic bridges between red blood cells was noted prior to clinical indication of renal dysfunction. Thus, these preliminary studies indicate that the development of cytoplasmic bridges between erythrocytes may be a diagnostic clue for early detection of renal dysfunction.

Serum complement and blood platelet adhesiveness in acute canine ehrlichiosis.

Three dogs inoculated with Ehrlichia canis served as infected controls (group I), 3 dogs treated with cobra venom factor (CVF) after inoculation with E canis were the principals (group II), 3 noninfected dogs were the noninfected controls (group III), and 1 noninfected dog given CVF was the noninfected, decomplemented control (group IV). Thrombocytopenia occurred in all E. canis-inoculated dogs (groups I and II) within 3 weeks after they were inoculated.
