Effect of direct therapeutic ultrasound exposure of ovaries on histopathology, inflammatory response, and oxidative stress in dogs.

Background: This research was designed to evaluate the effects of therapeutic ultrasound waves on ovarian germinal tissue and inflammatory cytokines (interleukin-6 (IL-6), IL1β, tumor necrosis factor-α (TNF-α)), acute phase proteins (serum amyloid A (SAA), C reactive protein (CRP)) and oxidative stress (total antioxidant capacity (TAC), and malondialdehyde (MDA)) in dogs. Twenty-six clinically healthy adult mix-breed female dogs were aligned into three groups. Laparotomy was performed in control (n = 6) and treatment (T5, n = 10; T10, n = 10) groups.

Ultrasonographic and macroscopic study of pregnancy in golden hamster.

Background: Hamster is widely used as an experimental model in the study of reproductive system. However, pregnancy diagnosis and aging always have been a challenge. ultrasonography have been used in diagnosis of pregnancy in some small laboratory animals, such as rabbits, rats, and mice.

A descriptive angiographic study of the uterine arteries during pregnancy, the postpartum period and CEH/pyometra in bitches.

The aim of this descriptive study was to monitor the changes in uterine arteries during pregnancy, postpartum period and pyometra in bitches using angiography. Fifteen uteri of mixed breed bitches on days 24, 30, 33, 40, 43, 47, 50 and 56 of pregnancy and weeks 1, 2, 3, 4 and 7-8 of postpartum and two CEH/pyometra bitches were examined after ovariohysterectomy. The results showed that with the onset of normal pregnancy and in about 30 ± 1 days of gestation, anastomoses begin to form between the left and right middle uterine arteries, developing during the next days and continuing until 4 weeks postpartum.

Echotexture Analysis of Prostate Parenchyma for Detection of Benign Prostatic Hyperplasia in Dogs.

Ultrasonography is one of the most common methods for the diagnosis of prostate disorders, such as benign prostatic hyperplasia (BPH), in dogs. Changes in the echotexture are one of the indicators used to diagnose prostate disorders. The purpose of this study was to investigate the changes occurred in the dogs' prostate echotexture during the induction of BPH using image analysis.

A preliminary study of transabdominal ultrasonic wave treatment on the germinal tissues of dog ovaries as a contraceptive approach.

The aim of this study was to investigate effects in dogs of ultrasonic waves on the ovarian germinal tissues. There was assignment of ovaries of each dog being a control (right ovary) or treated (left ovary) tissue, regardless of the estrous cycle status. For the treated ovary, the ultrasonic probe was set at a frequency of 1 MHz and power of 1.
