Benign prostatic hyperplasia (BPH) is a common disease in human that gradual overgrowth of the prostate gland leads to impinge on the urethra with impairment in urinary function. Numerous plants improve uncontrolled growth of the prostate gland and improve urinary tract symptoms associated with BPH. In this study, 25 healthy adult male Wistar rats were divided randomly in five groups: G1 (Contr...

The major lymphoid tissues in teleost fish are the kidneys, thymus, spleen and mucosa-associatedlymphoid tissue including the skin, gills and intestine. The head of kidney (pronephros) is an importanthaematopoietic organ and has morphological similarities with the bone marrow in higher vertebrates. In thisstudy, during 12 months from August 2002 to July 2003, 120 grass carp (10 fish/month) were...

Calcific Metamorphosis (CM) is a pulpal response to dental trauma characterized by a deposition of hard tissue within the canal space. A tooth with CM usually presents a discoloration and a partial or total obliteration of the pulp canal space, and its vital pulp tests and symptoms are difficult. Since pulp necrosis cannot be supposed even the negative responses, the periradicular status is the...

This study was carried out to determine distribution and heterogeneity of mast cells in the digestive tract of the both chicken and quail. Ten Leghorn chickens and ten Japan quails were use during the investigation. Having been sacrified by decapitation, the chickens and quails’ tongue, crop, esophagus, proventriculus, gizzard, duodenum, jejunum, ileum, caecum and colon tissue samples were take...

BACKGROUND In-vitro and animal studies using EDC cross-linked membranes have shown great resistance to enzymatic digestion as well as low cytotoxicity, and indicated its potential expediency as a barrier membrane for guided bone regeneration (GBR). The purpose of this study was to evaluate the efficacy, biocompatibility and degradation kinetics of a novel 1-ethyl-3-(3-dimethylaminopropyl) carbo...

Background: Up until now, the effect of thyroid hormones on the male reproductive organ, after puberty, is not well understood. OBJECTIVES: In the present study, the morpho-histometrical effects of thyroid hormone deficiency on the adult-male rat reproductive organs were investigated. MATHODS: Thirty adult male rats were randomly divided into three groups (n=10): control, hypothyroid, and hypot...

Introduction: Feathers are important body structures that act as surface insulators to reduce maintenance energy requirements and also to protect skin against abrasions and infection. The purpose of this study is to investigate the effects of methionine injection into the yolk sac on development of feather follicle in chicken embryo.
