In this research a 100 day long treatment period was considered to unmask the probable adverse effects of long-term induced hyperthyroidism on histomorphometrical attributes of the oviduct in broiler breeder hens. A total of seventy 47-week-old Cobb 500 breeder hens were randomly allotted to two treatment groups (5 replicates of 7 hens each). Thyroxine (T4) was orally administered to the hypert...

Fat-associated lymphoid clusters (FALCs) are novel tissues that have been reported in the mesenteric and mediastinal fat tissue of mouse human. It plays role progression respiratory intestinal inflammation parasitic infestations. However, their occurrence chicken air sacs adipose has not yet identified. Here we investigated distribution FALCs (cervical, clavicular, thoracic, abdominal) healthy ...

The present study aims to clarify corneal development via analyzing of the histomorphologic and some histochemical parameters in local rabbits. Samples were collected from 25 Rabbits divided into five different age groups at 1, 10, 15, 30, 40 postnatal day (PND), then samples sectioned, processed, stained with Hematoxylin eosin stain Masson’s trichrome stain. Some sections further periodic acid...

The purpose of this study was to evaluate the effects of simvastatin, by oral or subcutaneous administration, on tibial defects regeneration and blood cholesterol level in rats. A surgical defect was made on the right tibia of 40 male animals assigned to 4 groups (n=10), based on two routes of administration and on the use or not of simvastatin: subcutaneous injection of simvastatin (7 mg/kg) (...

The present study aimed to investigate the protective effects of Polycan, a β-glucan from Aureobasidium pullulans SM-2001, in a rat model of ovariectomy-induced osteoporosis. Ovariectomized (OVX) rats were orally administered 31.25, 62.5 or 125 mg/kg/day Polycan for 126 days, and alterations in body weight, bone mineral content, bone mineral density, failure load, histological profiles and hist...

In the current study, oligo(poly(ethylene glycol) fumarate) (OPF)-based hydrogels were tested for the first time as injectable bone substitute materials. The primary feature of the material design was the incorporation of calcium phosphate (CaP) nanoparticles within the polymeric matrix in order to compare the soft tissue response and bone-forming capacity of plain OPF hydrogels with CaP-enrich...

Placental morphology and cellular arrangement are altered in maternal diseases such as preeclampsia (PE) in which oxygen delivery from the mother to the fetus is greatly disturbed, ultimately resulting in cellular oxidative stress. The present study was conducted at the Department of Anatomy and included 112 placentas (56 each from mothers with and without PE [controls]) collected at the Depart...
