Echocardiographic parameters and indices in the normal beagle dog.

M-mode and two-dimensional echocardiographic measurements were made from the right sternal border of 50 healthy Beagles (25 males and 25 females) approximately 7 months old. The dogs were conscious and standing during the investigation. The following parameters, in systole and diastole, were measured on the echocardiographic images: left ventricular posterior wall thickness (LVWT); intraventricular septum thickness (IST); left ventricular internal dimension (LVID); and circumference (LVC). Fractional shortening (FS) and ejection fraction (EF) were also calculated. Mean, standard deviation, range and coefficient of variation are reported for each echocardiographic parameter and for body weight. Males and females were considered separately and together. Each parameter was analysed statistically to check for differences between the sexes and for correlations with body weight. A statistically significant difference between the sexes was only observed for LVWT in systole and diastole. A linear regression with body weight was obtained only for LVID in systole and in diastole. The results show that morphofunctional cardiac homogeneity is independent of size in dogs of this breed and age.

[Filling defects in the upper urinary tract: update on the etiologic diagnosis and review of the specific value of urinary cytology].

We present 3 cases with upper tract filling defect and exfoliative cytology positive for malignant cells in 2 of these cases (micturition and via ureteral catheter, respectively). The initial suspicion of urinary tract tumor was discarded by subsequent work up in 2 patients who were managed conservatively and followed closely. The third patient was submitted to nephroureterectomy. The histopathological examination disclosed chronic pyelonephritis and a deposit of amorphous mucoid material but no evidence of tumor. We review the etiologies of upper tract filling defects and present a useful diagnostic algorithm for the study of these conditions and the etiopathogenic and physiopathologic evaluation of the false positives in urinary cytology.

Anti-inflammatory constituents of topically applied crude drugs. IV. Constituents and anti-inflammatory effect of Paraguayan crude drug "alhucema" (Lavandula latifolia Vill.).

The anti-inflammatory active fraction of the Paraguayan crude drug, "Alhucema," Lavandula latifolia Vill. afforded four compounds: coumarin (1), 7-methoxycoumarin (2), trans-phytol (3) and caryophyllene oxide (4). 1 showed a weakly inhibitory effect on carrageenin-induced paw edema in rats on topical application and 4 showed an inhibitory effect on histamine-induced contraction in guinea pig ileum.

Xanthine oxidase inhibitory activity of Paraguayan Myrtaceae.

Nineteen Myrtaceae collections belonging to 15 species, 12 of which are used in Paraguayan folk medicine, were assayed for inhibitory activity towards the enzyme xanthine oxidase. Most leaf and stem extracts were active showing IC50 values ranging from 3.0 to 50 micrograms/ml. The reported activities support existing ethnobotanical data concerning their use for the treatment of gout.

[Idiopathic "benign" pericarditis in dogs. Clinical and therapeutic reflections].

The authors present a case of benign idiopathic pericarditis in dog, describing a clinical case. The most important reasons for pericardial effusion are analyzed. Clinical signs of cardiac tamponade and aspects of electrocardiographic examination are demonstrated. Inconsistent long-term results achieved using corticosteroid therapy induced the authors to perform partial pericardiectomy (pericardial fenestration). The surgical approach was curative and, one year later, the dog doesn't show any signs of clinical disease.

Preliminary pharmacological studies on Eugenia uniflora leaves: xanthine oxidase inhibitory activity.

Eugenia uniflora is widely used in Paraguayan folk medicine. A hydroalcoholic extract of the leaves showed some central nervous system activity in hippocratic screening when given intraperitoneally, but little to no acute or subacute toxicity in doses up to 4200 mg/kg orally in BALB c mice. The LD50 of the extract was 220 mg/kg i.p. in mice. A decoction or infusion of the leaves is recommended for treating gout by native herbalists. The known flavonoids quercitrin, quercetin, myricitrin and myricetin were found to be responsible for the xanthine oxidase inhibitory action of the plant extract.
