the aim of the present study was to investigate the light and electron microscopic structure of the tongue in white-eared bulbul (pycnonotus leucotis). six adult white-eared bulbul (3 males and 3 females) in shahrekord district were used in the investigation. samples of the apex, body and root of the tongue were prepared routinely for light and electron microscopic study. results showed that th...

The secretory cells of the salivary glands of the snail, Helisoma trivolvis, exhibit regenerative, overshooting action potentials whose ampliture may exceed 100 mV. The salivary glands consist of paired, tubular, epithelial structures with acinar outpocketings. The secretory cells display extensive electrical coupling which allows action potentials to propagate along the glandular epithelium. S...

We report a case of florid polypoid endometriosis presenting with advanced bulky disease in pelvis with serum CA – 125 levels of 7844U/ml. The extent of tumor, CT scan findings, elevated serum CA – 125 levels were suggestive of ovarian malignancy. Histopathology demonstrated endometrial glands and stroma. Glands were neither crowded nor complex and were separated by a fibromatous stroma that co...

Salivary glands are important for secretion of saliva, which is essential for bolus formation, swallowing and maintaining a healthy oral cavity [1]. Salivary glands consist of acinar and duct cells. Injury to salivary glands, such as the damage that occurs following radiation treatment for head and neck cancer, causes a decrease in the number of acinar cells and the ability of the glands to pro...

Ultrasound is one of the preferred modalities for evaluation of the parathyroid glands. This study was undertaken to determine the accuracy of high resolution ultrasound for secondary hyperparathyroidism in patients with chronic renal failure. From March 2008 to March 2009, ninety-one hemodialysis patients were examined by high resolution ultrasound (14 MHz) of the parathyroid glands in compari...

As it regulates important physical functions and general wellbeing, the hypophysis plays a major role in responding to increased demand for different hormones. In current review, we described anatomical histological structures of pituitary glands domestic animals. Unlike other glands, gland has two main parts; adenohypophysis (anterior lobe), which contains multiple populations endocrine cells ...
