Introduction This study aims to quantify the shear wave speed (SWS) and stiffness of the uterine cervix (close to the internal cervical ostium (IOC) which is the cranial portion of cervix and close to the external cervical ostium (EOC) which is the caudal portion of cervix), caruncular areas, and vulvar labia during the postpartum period in healthy...

Background: Magnesium (Mg) is the 4 th most abundant cation in the mammalian body. Mg activates many enzymes and affects the nerve conduction, uterine contractility and other smooth muscle contractility. Mg is a calcium antagonist. Its effect on uterine smooth muscle is relaxation and tocolysis. Decrease of Mg plays an important role in labor and d...

Background: One of the potentially serious eye injuries that can lead to blindness in cats is "full-thickness corneal lacerations and perforations." These injuries require immediate medical intervention, and if left untreated, they can lead to complications such as the risk of infection. Treatment typically depends on the size, depth, and severity...

The aim of this study was to evaluate the differences in the platelet (PLT) indices and complete blood count (CBC) parameters between the cats with mammary tumor and healthy individuals. Also, the differences in above mentioned parameters are going to be investigated in cats with mammary tumors with regard to clinicopathological characteristics of...

The aim of this study was to evaluate the changes in calcium, phosphorus and some biochemical parameters in dogs with open and closed cervix pyometra, which was then compared with a control group. A total of 62 bitches of age group 5-10 years old irrespective of breed were enrolled into the study. Control group consisted of 22 bitches which were cl...

Cysts, fluid accumulation, inflammatory changes and tumors are common uterine pathologies in mares. It was aimed to investigate the change of uterine hemody­namics in mares according to uterine pathologies (endometritis or intrauterine cysts). The study contained 28 mares and the groups formed as 9 gynaecologically healthy diestrus mares (Group H),...

Background: Alpha-fetoprotein (AFP) is a fetal protein that was first defined in 1956 and has been used since the 1970s to identify high-risk pregnancies for abnormalities in gynecology. First description of fetal protein was by Bergstrand and Czar in 1956 in humans and named as ''alpha-fetoprotein'' (AFP). AFP was found in the electrophoresis of f...

ÖZET Amaç: Kısraklarda üreme organlarının fizyolojik durumunu değerlendirmenin yanı sıra biyolojik ve patolojik reprodüktif olaylarını teşhisi amacıyla B-mod ultrasonografiden faydalanılmaktadır. Reprodüktif organların fonksiyonlarını ve hemodinamik yapılarını değerlendirmek için ise noninvaziv bir yöntem olan transrektal renkli Doppler (RD) ultras...

Güç doğum, doğumun birinci veya ikinci aşamasının uzamasıyla buzağıyı doğurmak için daha fazla yardım gerektiren, uzayan veya zor doğum olarak tanımlanır. Distosi olarak adlandırılan zor doğum, sığır gebeliklerinin %3-25'inde meydana gelir. Toplam performanstaki düşüşün ve bunun neticesinde olu-şan ekonomik kaybın ana nedenidir. Buzağılama zorluk s...

Background: Hormonal and physiological changes during pregnancy period have significant effects on animals' metabolisms. The purpose ofthe present study is to evaluate the variations of aspartate aminotransferase (AST) and gamma-glutamyl transferase (GGT) levels according to different gestation trimesters of the pregnant mares to assess changes of...

Eight dogs with a vaginal mass were incorporated into the study. According to the vaginal examination (vaginoscopy, exfoliative vaginal cytology) and histopathology, the groups were designed as vaginal fold prolapse (Group VFP; n=3) and vaginal tumor (Group VT; n=5). Vaginal tissue samples were homogenized. Tissue homogenates were analyzed with enz...

Background: Pyometra is defined as chronic purulent inflammation of the uterus that causes changes in hematological and biochemical parameters. The disease is characterized with bacterial infection and pus accumulation in the uterus. Transabdominal B-mode ultrasonography provides easy and certain diagnosis of this disease. The hemodynamic changes i...

Endometritis is a major cause of infertility in mares. The aim of this study is to evaluate the preovulatory follicle (POF) vascularization (A mix, A red, A blue), POF diameter, POF wall thickness, and uterine diameters in mares with or without endometritis. Ten healthy mares and 10 mares with endometritis diagnosed by the combination of transrecta...

The aim of this study is to determine the relationship between the amount of vascularization in the preovulatory follicle wall and pregnancy establisment with colour Doppler ultrasonography. Colour Doppler ultrasonography images from 26 Arabian mares in breeding season were evaluated in the study. Mares no abnormalities in the reproductive system a...

A thirteen-year-old, Arabian breed mare which had delivered four times; was presented to Istanbul University, Faculty of Veterinary Medicine, Clinic of Obstetrics and Gynaecology with lack of oestrus signs and exhibition of stallion-like behaviour. Due to the rectal palpation and transrectal ultrasonography, a mass was detected at the right ovary....

The aim of the study was to evaluate the effects of single and double inseminations on the inflammation of the uterus in mares. Nine mix breed mares with endometrial biopsy scores grade I and IIA, aged 5-15, were used in the study. Two experiments were performed over two estrous cycles: (1) single insemination, (2) double insemination. All mares we...

Doppler ultrasonography is a noninvasive technique which enables us to follow the physiologic and physiopathologic changes in blood flow in tissues. It is becoming an essential tool in veterinary medicine, especially in theriogenology. Twenty-seven Arabian mares were grouped by age (‘young’, 3–10 y, n = 15; ‘old’, 19–23 y, n = 12). The uterine arte...
