Fatty acid composition and antioxidant properties of cold-pressed marionberry, boysenberry, red raspberry, and blueberry seed oils     

Parry J  Su L  Luther M  Zhou K  Yurawecz MP  Whittaker P  Yu L 《Journal of agricultural and food chemistry》2005,53(3):566-573

Cold-pressed marionberry, boysenberry, red raspberry, and blueberry seed oils were evaluated for their fatty acid composition, carotenoid content, tocopherol profile, total phenolic content (TPC), oxidative stability index (OSI), peroxide value, and antioxidant properties. All tested seed oils contained significant levels of alpha-linolenic acid ranging from 19.6 to 32.4 g per 100 g of oil, along with a low ratio of n-6/n-3 fatty acids (1.64-3.99). The total carotenoid content ranged from 12.5 to 30.0 micromoles per kg oil. Zeaxanthin was the major carotenoid compound in all tested berry seed oils, along with beta-carotene, lutein, and cryptoxanthin. Total tocopherol was 260.6-2276.9 mumoles per kg oil, including alpha-, gamma-, and delta-tocopherols. OSI values were 20.07, 20.30, and 44.76 h for the marionberry, red raspberry, and boysenberry seed oils, respectively. The highest TPC of 2.0 mg gallic acid equivalents per gram of oil was observed in the red raspberry seed oil, while the strongest oxygen radical absorbance capacity was in boysenberry seed oil extract (77.9 micromol trolox equivalents per g oil). All tested berry seed oils directly reacted with and quenched DPPH radicals in a dose- and time-dependent manner. These data suggest that the cold-pressed berry seed oils may serve as potential dietary sources of tocopherols, carotenoids, and natural antioxidants.  相似文献   

Foreign body obstruction of the small colon in six horses.     

C C Gay  V C Speirs  B A Christie  B Smyth  B Parry 《Equine veterinary journal》1979,11(1):60-63

Six horses, which had a foreign body obstruction of the small colon showed abdominal pain of progressing severity and intestinal tympany. On rectal examination the caecum and large colon were distended with ingesta and gas but the obstructing mass could be palpated in only 3 cases. All horses had elevated indirect blood pressure and in 3 there was also fluid distension of the stomach. Only one horse had known access to foreign material in the diet, but a further 3 were related to an exceptionally dry climate period. Five of the 6 horses recovered following surgery.  相似文献   

Cytology of the canine reproductive system   总被引：2，自引：0，他引：2  

P J Wright  B W Parry 《Veterinary Clinics of North America: Small Animal Practice》1989,19(5):851-874

The methods for semen collection, its laboratory examination, and the interpretation of findings are presented in this article. The lack of comprehensive data for normal dogs and the lack of data associating actual percentages of spermatozoa with specific abnormalities with fertility or infertility are highlighted. Consequently, there is a need for standardization and completeness of semen examination procedures, especially in studies destined for publication. Collection and analysis of prostatic samples then is discussed, and the distinguishing cytological features of benign prostatic hyperplasia, prostatic adenocarcinoma, prostatis (including prostatic abscessation), and prostatic cysts are presented. This is followed by an assessment of the clinical usefulness of vaginal cytology, particularly to assist in the management of normal canine reproduction and in the diagnosis of reproductive disorders. The ways in which vaginal smears can facilitate the diagnosis of the stage of the estrous cycle and the diagnosis of abnormalities of the cycle and other disorders of reproduction are presented. Further consideration is given to its use to estimate the time of ovulation retrospectively and estimate the time of whelping prospectively. Finally, two specific diseases that can affect dogs and bitches are reviewed, namely, canine brucellosis and transmissible venereal tumor.  相似文献   

Survey of 79 referral colic cases     

B W Parry 《Equine veterinary journal》1983,15(4):345-348

The clinical, surgical and/or necropsy diagnosis of 79 horses admitted to a referral clinic for evaluation of colic are reported. Twenty-one horses were presented with conditions amenable to medical treatment and all were subsequently discharged. Exploratory laparotomies were performed on 44 horses during the present study, in some cases as a diagnostic procedure preceding euthanasia. In general, in surgical cases the mortality rate was highest for problems involving the small intestine, followed by those affecting the large colon and then the small colon. Postoperative sequelae included peritonitis, infarction, visceral rupture and acute circulatory failure. Colitis, visceral rupture and thromboembolic infarction generally had a fatal result. The overall recovery rate (for 79 horses) was about 50 per cent.  相似文献   

Indirect measurement of blood pressure as a guide to the efficacy of fluid therapy in equine shock: A case report     

B.W. Parry BVSc  PhD  B.A. Christie BVSc  MACVSc  C.C. Gay DVM  MVSc  FACVSc  R.N. Haywood BVSc   《Journal of Equine Veterinary Science》1983,3(1):24-27

A case of acute circulatory failure in a horse is described. The response to intravenous fluid therapy was monitored by measurement of heart and respiratory rates, and arterial and central venous pressures. Heart rate was an unreliable guide to improved circulatory status. Central venous pressure and indirect arterial blood pressure were valuable guides to the efficacy of fluid therapy.  相似文献

Formation of high levels of acrylamide during the processing of flour derived from sulfate-deprived wheat     

Muttucumaru N  Halford NG  Elmore JS  Dodson AT  Parry M  Shewry PR  Mottram DS 《Journal of agricultural and food chemistry》2006,54(23):8951-8955

When wheat was grown under conditions of severe sulfate depletion, dramatic increases in the concentration of free asparagine were found in the grain of up to 30 times as compared to samples receiving the normal levels of sulfate fertilizer. The effect was observed both in plants grown in pots, where the levels of nutrients were carefully controlled, and in plants grown in field trials on soil with poor levels of natural nutrients where sulfate fertilizer was applied at levels from 0 to 40 kg sulfur/Ha. Many of the other free amino acids were present at higher levels in the sulfate-deprived wheat, but the levels of free glutamine showed increases similar to those observed for asparagine. In baked cereal products, asparagine is the precursor of the suspect carcinogen acrylamide, and when flours from the sulfate-deprived wheat were heated at 160 degrees C for 20 min, levels of acrylamide between 2600 and 5200 microg/kg were found as compared to 600-900 microg/kg in wheat grown with normal levels of sulfate fertilization.  相似文献

Primary hypoparathyroidism in dogs: a retrospective study of 17 cases     

Russell NJ  Bond KA  Robertson ID  Parry BW  Irwin PJ 《Australian veterinary journal》2006,84(8):285-290

OBJECTIVE: To evaluate the clinico-pathological findings, response to treatment and prevalence of complications in dogs with primary hypoparathyroidism. DESIGN: Retrospective study of 17 dogs presenting to the University of Melbourne Veterinary Clinical Centre and Murdoch University Veterinary Hospital over a 15 year period (1990 to 2004). Case records were evaluated for signalment, body weight, diet type, historical and clinical findings, serum total calcium, phosphate, albumin and parathyroid hormone concentrations, urinary fractional excretion ratios of calcium and phosphate, electrocardiogram (ECG) results, treatments administered, outcome and period of follow-up. RESULTS: The most common breeds identified were St Bernard (three dogs), Chihuahua (two dogs), German Shepherd (two dogs) and Jack Russell Terrier (two dogs). Three dogs were cross bred. Seizures, muscle tremors and fasciculations, stiff gait, tetany, muscle cramping, behavioural change and hyperventilation were the most common clinical signs. Vomiting, inappetence, diarrhoea, abdominal pain, hyperthermia, facial pruritus, ataxia, weakness, cataracts, and circling also occurred with less frequency. The mean duration of observed clinical signs preceding diagnosis was 33 days (median 13 days, range 1 to 173 days). All dogs had marked hypocalcaemia with normal or mildly increased serum albumin concentrations. Mean phosphate concentrations were significantly higher in inappetent dogs (P = 0.049). Mean serum calcium concentrations were significantly lower in dogs with cataracts compared to those without (P = 0.046). There were no other significant relationships between serum calcium or phosphate concentrations and the clinical presentation or outcome. No significant correlations were identified between the presence of a particular clinical sign and the duration of clinical signs. ECGs were obtained in four dogs and all exhibited QT interval prolongation due to a ST-segment prolongation. Sixteen of 17 dogs were treated successfully for hypocalcaemia and discharged from hospital. Acute management included parenteral calcium gluconate (10 dogs) and intravenous anticonvulsants (five dogs). Chronic therapy included oral vitamin D analogues and calcium supplementation. Treatment complications occurred in two dogs and included acute renal failure (one dog) and iatrogenic tissue necrosis following subcutaneous calcium administration (one dog). The mean follow-up period was 14.5 months (median 13 months, range 0 to 39 months). Twelve dogs were alive at the last follow up and two dogs were euthanased for unrelated reasons. The type of vitamin D analogue used was not associated with outcome. CONCLUSION: Primary hypoparathyroidism was an uncommon diagnosis in dogs. Saint Bernards, cross bred dogs, German Shepherd dogs and Terrier breeds were most commonly affected. Neurological signs were the most common presenting clinical signs, although alimentary signs may have been more common than previously reported. Dogs with primary hypoparathyroidism appeared to have a good prognosis following initiation of calcium supplementation and vitamin D therapy. Complications of treatment were uncommon and could be minimised with regular monitoring.  相似文献
