“…The capsular limit is not well defined. Systolic and diastolic peak velocity, the end-diastolic velocity, resistive index and pulsatility index values were increased in accordance with other published values [9]. Doppler examination shows increased blood flow within prostate with high fractional area index [2].…”

Prostate cancer is one of the most important malignancies in men. In old men the frequency of prostate cancer at necroscopy has been reported to exceed 40%. Dogs are the only large mammals other than humans with a significant incidence of spontaneous prostate cancer. Adenocarcinoma, transitional cell carcinoma and undifferentiated carcinoma are the most common histological type but the precise cell of origin in dog is not known. The incidence of prostatic carcinoma in dogs is low (0.2% -0.6%). Prostatic carcinomas occur in sexually intact and neutered dogs and the risk increase in castrated dogs associated to pulmonary and bone metastases. The castration does not initiate the development of prostatic carcinoma in dog but does favour tumour progression. In men the early stage detection of prostate cancer can offer various therapies as radical prostatectomy, radial therapy, thermal ablation, anti-androgen therapy, chemotherapy. In dogs the diagnosis is often in advanced stage of the cancer and the survival time for dogs with prostate cancer is poor. The median time reported is 30 days after diagnosis. In this study we reported three cases of prostatic carcinoma in intact sexually dogs and one in a neutered dog. The sexually intact subjects were older (mean age = 10.5 years) and they had prostatic adenocarcinoma (PCA). The interval between castration and onset of prostatic problems was 3 years. All the dogs showed dysuria, macroscopic hematuria, dyschezia and ataxia. All dogs have been euthanized in order to relieve pain and suffering.

“…The dorsal penile artery supplies those body organs (penis) that should be targets for sex pheromones, whereas the arcuate artery is the vessel of a control organ-the kidney (Dzięcioł et al 2012b). To visualize the examined vessel, color coded ultrasonography was used (Gunzel-Apel et al 2001). For the evaluation of the results Pixel Flux ® software (Chameleon Software, Germany) dedicated for dynamic sonographic tissue perfusion measurement was used , Scholbach et al 2004, Wieczorek et.…”

The aim of this study was to evaluate the suitability of synthetic bitch sex pheromones (Eau' De Estrus ® , Synbiotics USA) for the stimulation of the reproductive reflexes in adult male dogs. In experiment I: anoestral bitches were applied synthetic (n=6) or natural (n=6) pheromones and their attractiveness was compared to the attractiveness of bitches in natural oestrus, In experiment II: swabs socked in natural estrual discharge or Eau D'Estrus were presented to male dogs and behavioral arousal (Exp. II a) and changes in blood flow in the penile artery reflecting erection (Exp. II b) were recorded. In experiment III the time dedicated for sniffing in experimental dogs was analyzed in relation to the type of attractant presented (natural estrual discharge or Eau D'Estrus). In all three experiments we observed the signs of sexual arousal, increased blood flow in the penile artery and increased time of sniffing only with natural pheromones. No signs of excitation or changes in penis perfusion were noted after the use of artificial pheromones. Our results did not support the suitability of Eau D'Estrus for male dog sexual stimulation.

“…The usefulness of the Doppler sonography for the examination of canine testes is described in several reports (5,11,12). However, Pozor and McDonnell (23), who examined stallions` testes with the pulsedwave gray-scale Doppler ultrasonography, found this method very helpful, despite much bigger size of the testes.…”

The aim of this study was to investigate the usefulness of new software Pixel Flux (PXFX) for clinical evaluation of tissue perfusion in the field of reproduction in dogs. The experiment was performed on six adult Beagle dogs. Different organs and tissues of the animals were examined with the MyLab25 Gold ultrasound system. Blood flow in the ovary, testicle, prostate, the ramification of the penile artery, and the network of blood vessels of the pampiniform plexus were examined with the use of colour coded Doppler technique, and obtained data was evaluated with the PXFX software. The more objective digital evaluation of data obtained with colour Doppler sonography through the application of dynamic tissue perfusion measurements provides new opportunities for diagnosis, as well as continuous monitoring of the function of the examined tissues and organs. The use of PXFX software is strongly indicated as a tool in small animal practice as an additional method for evaluation of tissue perfusion, especially in the cases when other methods like pulsed wave Doppler techniques are difficult to be performed.
