Nicotine in cigarette smoke is one of the toxic substances which impair the fertility. In this research the effects of nicotine tartrate on female albino rat’s reproductive system was studied. The rats were divided into 4 groups. Group I: control animals received normal saline, Group II: injected with nicotine 4mg/kg, Group III: injected with nicotine4mg/kg and Meliaazedarach 100mg given orally...

Bacterial cellulose (BC) is an excellent biomaterial with many medical applications. In this study, resorbable BC membranes were prepared for guided bone regeneration (GBR) using an irradiation technique for applications in the dental field. Electron beam irradiation (EI) increases biodegradation by severing the glucose bonds of BC. BC membranes irradiated at 100 kGy or 300 kGy were used to det...

Introduction Small fiber involvement in different patterns of peripheral neuropathy has stirred much interest during the past few years due to the role played by these fibers in pain perception and the availability of new techniques of skin biopsy that permit the study of nerve endings [1]. The use of protein gene product 9.5 (PGP 9.5) as a panaxonal marker in skin biopsies has led to identific...

The purpose of this study was to determine how accurately periodontal probes measure connective tissue attachment levels in beagle dogs with (1) clinically healthy gingivae, (2) experimental gingivitis, and (3) periodontitis. In the healthy and experimental gingivitis specimens the probes were inserted with a standardized force of 25 ponds. In periodontitis specimens the probes were inserted wi...

PURPOSE The aim of this study was to determine the effect of recombinant human bone morphogenetic protein-2 (rhBMP-2)-loaded synthetic bone substitute on implants that were simultaneously placed with sinus augmentation in rabbits. METHODS In this study, a circular access window was prepared in the maxillary sinus of rabbits (n=5) for a bone graft around an implant (Ø 3×6 mm) that was simultan...

OBJECTIVES The purpose of this study was to evaluate the effect of Chamomilla recutita on the healing of ulcers in rats. STUDY DESIGN A 5-mm wound was inflicted on the tongue of 36 rats. Treatment group animals were treated topically with 0.04 mL/day of chamomile ointment, whereas control group animals were not treated. Animals were sacrificed after 3, 7 or 10 days. Semi-quantitative analysis...
