Comparison Of Gastric Emptying Times In Healthy Cats Simultaneously Evaluated With Radiopaque Markers And Nuclear Scintigraphy, J Goggin, J Hoskinson, Claudia Kirk, D Jewell, M Butine Dec 1998

Comparison Of Gastric Emptying Times In Healthy Cats Simultaneously Evaluated With Radiopaque Markers And Nuclear Scintigraphy, J Goggin, J Hoskinson, Claudia Kirk, D Jewell, M Butine

Claudia A Kirk

Gastric emptying in 18 healthy cats was assessed simultaneously using scintigraphy and barium-impregnated polyethylene spheres (BIPS). Canned Prescription Diet Feline c/d (Hill's Pet Nutrition, Inc., Topeka, KS) labeled with 99mTc-disofenin (Hepatolite, DuPont Merck Pharmaceutical Co., Billerica, Mass.) was fed on four separate days. Scintigraphic images were obtained at time 0 and then every 30 minutes to 6 hours. On the fourth scan day, 30 small (1.5 mm) and 10 large (5 mm) BIPS (Chemstock Animal Health Ltd., Christchurch, New Zealand) were mixed with the labeled meal, and in addition to scintigraphy, radiographs were made at 60-minute intervals ...

Taurine Status In Cats Is Not Maintained By Dietary Cysteinesulfinic Acid, S Edgar, Claudia Kirk, Q Rogers, J Morris Mar 1998

Taurine Status In Cats Is Not Maintained By Dietary Cysteinesulfinic Acid, S Edgar, Claudia Kirk, Q Rogers, J Morris

Claudia A Kirk

Endogenous synthesis of taurine by cats is limited. Putative precursors of taurine, cysteinesulfinic acid and cysteic acid, were fed to cats to determine whether they were utilized. Groups of five cats were depleted of taurine by a resin (Colestipol(R)) diet, then given 6 dietary treatments containing (g/kg diet): 0.0, 0.4, or 0.8 taurine; or 0.98 or 1.96 cysteinesulfinic acid, or 0.4 taurine + 1.0 cysteic acid for 12 wk. Plasma and whole blood taurine concentrations and body weights were measured weekly. Concentration of taurine in semitendinosus muscle was measured initially, after 2 ...


Dietary Taurine Needs Of Cats Vary With Dietary Protein Quality And Concentration, R Backus, J Morris, S Kim, J O'Donnell, M Hickman, Claudia Kirk, J Cooke, Q Rogers Dec 1997

Dietary Taurine Needs Of Cats Vary With Dietary Protein Quality And Concentration, R Backus, J Morris, S Kim, J O'Donnell, M Hickman, Claudia Kirk, J Cooke, Q Rogers

Claudia A Kirk

The influence of dietary protein on the taurine requirement of cats was evaluated by analysing the results from several experiments in which taurine status of cats was assessed after several weeks of feeding purified and commercial diets. The diets varied in taurine content, protein source and protein concentration, with some diets cooked or containing cooked ingredients.The quality and concentration of dietary protein affected taurine requirement. As indicated by digestibility estimates, taurine requirement increased when protein quality decreased. When diets containing protein in excess of that required were fed, the need for taurine was increased by increasing dietary protein level ...

Evaluation Of Factors Associated With Development Of Calcium Oxalate Urolithiasis In Cats, Claudia Kirk, G Ling, C Franti, J Scarlett Nov 1995

Evaluation Of Factors Associated With Development Of Calcium Oxalate Urolithiasis In Cats, Claudia Kirk, G Ling, C Franti, J Scarlett

Claudia A Kirk

OBJECTIVE: To evaluate dietary and environmental factors as potential risk factors for calcium oxalate urolithiasis in cats. DESIGN: Case-control study. ANIMALS: 84 cats with uroliths composed of at least 90% calcium oxalate and 258 age- and gender-matched control cats. PROCEDURE: Owners of cats with calcium oxalate urolithiasis and control cats were surveyed between November 1990 and August 1992. Owners completed a standard questionnaire administered during a single telephone interview. Data collected included information regarding signalment, environment, urination and defecation, diet, and medical history. RESULTS: Calcium oxalate uroliths tended to develop in middle- to older-aged, domestic shorthair cats of typical weight ...


Experimental Induction Of Hepatic Lipidosis In Cats, V Biourge, J Groff, R Munn, Claudia Kirk, T Nyland, V Madeiros, J Morris, Q Rogers Aug 1994

Experimental Induction Of Hepatic Lipidosis In Cats, V Biourge, J Groff, R Munn, Claudia Kirk, T Nyland, V Madeiros, J Morris, Q Rogers

The effect of long-term voluntary fasting on hematologic variables, biochemical profiles, and liver histologic findings was assessed in 15 obese cats (> 40% overweight). Clinical signs and laboratory results consistent with hepatic lipidosis were observed in 12 of 15 cats after 5 to 7 weeks of fasting, and were associated with 30 to 35% reduction of initial body weight. Histologic examination of successive liver biopsy specimens revealed that obesity was not associated with liver parenchymal lipid accumulation, but that fasting resulted in lipidosis in all 15 cats. The long-term fast was associated with an early (after 2 to 4 weeks of ...

Diagnosis Of Naturally Acquired Type-I And Type-Ii Diabetes Mellitus In Cats, Claudia Kirk, E Feldman, R Nelson Feb 1993

Diagnosis Of Naturally Acquired Type-I And Type-Ii Diabetes Mellitus In Cats, Claudia Kirk, E Feldman, R Nelson

Claudia A Kirk

After IV administration of 0.5 mg of glucagon/cat, glucose tolerance and insulin secretory response were evaluated in 10 lean cats, 10 obese cats, and 30 cats with diabetes mellitus. Blood samples for glucose and insulin determinations were collected immediately before and at 5, 10, 15, 30, 45, and 60 minutes after IV administration of glucagon. Baseline serum insulin concentration and insulin secretory response were used to classify diabetes mellitus in the 30 cats as type I or type II. Mean (+/- SEM) baseline and 30-minute serum glucose concentrations in obese cats were significantly (P < 0.05) decreased, compared with ...


Effect Of Glipizide On Serum Insulin And Glucose Concentrations In Healthy Cats, A Miller, R Nelson, Claudia Kirk, L Neal, E Feldman Dec 1991

Effect Of Glipizide On Serum Insulin And Glucose Concentrations In Healthy Cats, A Miller, R Nelson, Claudia Kirk, L Neal, E Feldman

Claudia A Kirk

With the recent identification of non-insulin-dependent diabetes mellitus (NIDDM) in cats, new possibilities arise for the use of oral hypoglycaemic agents in the treatment of feline NIDDM, similar to their use in humans. To identify the future applicability of the oral hypoglycaemic agent, glipizide, in the treatment of feline NIDDM, its effects on serum insulin and glucose concentrations in healthy cats was examined. In addition, adverse effects seen clinically or on bloodwork following short-term use of the drug were looked for. Serum insulin and glucose concentrations were evaluated after the oral administration of 2.5, 5.0 and 10.0 ...


Intracavitary Cisplatin Chemotherapy Experience With Six Dogs, A Moore, Claudia Kirk, A Cardona Dec 1990

Intracavitary Cisplatin Chemotherapy Experience With Six Dogs, A Moore, Claudia Kirk, A Cardona

Claudia A Kirk

Six dogs with a median age of 7 years (range = 5-14 years) were presented for signs referable to thoracic or abdominal effusion associated with neoplasia of the body cavities. Intracavitary cisplatin was administered at 50 mg/m2 every 4 weeks for a median of 2.5 treatments (mean = 3, range = 1-6). Three dogs with pleural mesothelioma had complete resolution of effusion for 289, 129, and greater than 306 days without evidence of tumor growth. Resolution of effusion occurred after one treatment in two dogs and after two treatments in one dog. In three dogs with carcinomatosis of unknown origin, complete ...


The Diagnosis And Treatment Of Insulin-Dependent And Non-Insulin-Dependent Diabetes Mellitus In The Dog And The Cat, Claudia Kirk, M Wallace Nov 1990

The Diagnosis And Treatment Of Insulin-Dependent And Non-Insulin-Dependent Diabetes Mellitus In The Dog And The Cat, Claudia Kirk, M Wallace

Claudia A Kirk

Diabetes mellitus is often a frustrating disorder to treat. Many animals appear resistant to the effects of insulin, while others, especially cats, are very sensitive to its effects and therefore prone to bouts of hypoglycemia. Because of difficulties in glucose regulation, many veterinarians have referred to the treatment of diabetes mellitus as an art rather than a science. Fear of over-regulation with resultant hypoglycemia has led to the practice of "loose control" (wide fluctuations of glucose are allowed to occur throughout the day). Fortunately, long-term side effects of poor glycemic control seen in people (eg, retinal, glomerular, vascular, and nerve ...
