In the present study, pancreas glands in Mehraban breed of female sheep were histomorphometricallystudied in four different age groups included: fetus, newborn, sexually mature and old ages. The results ofhistomorphometrical analysis with regard to frequency and percentage of parenchymal and stromal structures such as, exocrine secretory units, secretory ducts, blood vessels, islets of Langerha...

background: inverse relationship between helminths infection and immune-mediated diseases has inspired researchers to investigate therapeutic potential of helminths in allergic asthma. helminth unique ability to induce immunoregulatory responses has already been documented in several experimental studies. this study was designed to investigate whether excretory/secretory (es) and somatic produc...

abstract background: the children with middle ear effusion need repeated re-tympanostomies. adenoidectomy is an effective surgical intervention in the management of chronic otitis media with effusion in conjunction with in-sertion of tympanostomy tubes (tts). to find out whether tts in different positions decrease the rate of re-tympanostomies study was done. methods: the present study retrospe...

background: recent attention has focused on the expression of integrin molecules within the endometrium, and their relation to infertility. objective: the present prospective study was undertaken to determine whether the endometrium of women with unexplained infertility differs in the expression of very late activation antigens (vla) from the endometrium of normal fertile women. methods: thirty...

background: sparganosis is caused by the invasion of spirometra sparganum into various tissues/organs. subcutaneous sparganosis can be diagnosed by biopsy , while visceral/cerebral sparganosis is not easy to be diagnosed. the diagnosis de-pends largely on the detection of specific anti-sparganum antibodies. t he specific-ity of the elisa could be increased by using s. mansoni sparganum excretor...

tial, as seen from an initial rapid rise of each slow PHI in Fig. 3, but the contamination is again small enough for the present purpose. The three sets of tracings in Fig. 3, B, show the result of simulation with the use of the circuit in Fig. 1, B, with three different values of time constant (4.5, 9, and 18 sec) and each rod potential in Fig. 3, A, used as an input. The tracings show that th...

A distinct system of immunity in a variety of animals is located subjacent to epithelial surfaces and is typified by the predominance of immunoglobulin A (IgA) and secretory component (SC) in various external secretions, including tears. The present study examined normal rabbit lacrimal gland, conjunctiva, and cornea for the presence of immunoglobulin and SC. IgA-staining plasma cells predomina...

Most pituitary tumors are benign conditions and rarely malignant. These divided into secretory non-secretory based on the tumor’s capability of secreting hormones. A study conducted in UK showed a prevalence 77.6 adenoma cases out 100000 people.
