Aim of the study: Is to evaluate the effect of myrrh oil local application on the healing process of skin wounds histologically , histomorphometrically and , histochemically. Materials and methods:Twenty male white New Zealand rabbits were used in this study. An incisional wounds with full thickness depth and of 2 cm length were done on both sides of the cheek skin of each rabbit. The left sided incisions (the control group) were irrigated with distilled water (10µL). The right sided incisions (the experimental groups) were treated with myrrh oil (10µL). Each group was subdivided into 4 subgroups according to the healing interval into 1,3,7 and 14 days(5 rabbits for each group). Results: Histological findings of our current study showed a highly significant difference between the experimental and the control groups in count of the inflammatory cells which showed that mean values increased with time for the control and the experimental groups. The histomorphometrical findings had shown that the thickness of the epithelium was nearly completed at about 7 days for the experimental groups and at about 14 days for the control. The blood vessels count was recorded to have a highly significant difference between the groups at days 1 and 3 only. The histochemical findings had shown that the collagen fibers remodeling had recorded a highly significant difference between the control and the experimental groups at days 7 and 14. Conclusion: The current study had revealed that myrrh oil accelerates wounds healing in rabbits. Key word:Wound healing , Myrrh oil, Masson’s Trichrome staining.
The present study aimed to investigate the morphological and histological structure of pancreas in the bat,(Pipistrellus kuhlii). Pancreas was represented by compact pancreatic tissue which is divided into three parts : head , body and tail, its color is whit to yellow. The pancreatic tissue is located in the abdominal cavity near to the mass of intestine in the mesenteric network , which is connected with the coiled region of the duodenum in one side and with the extended mesenteries between the dorsal part of stomach and the abdominal part of spleen from the other side. The pancreas gland is surrounded by a loose connective tissue, the trabeculae are extended from it and divided the gland into many lobules which are different in shape

have become world –wide as an “instant treatment”
Materials & Methods: Tribulus terrestris was given daily to mature male mouse in a dose of 2 mg /kg body weight for 14 days .10% formalin fixed
paraffin sections were performed for histological, histochemical and morphometrical studies.
Results: Histological and histochemical studies demonstrated a considerable increase in the number of spermatocytes, spermatids and sperms in parallel
with an increase number of interstitial (Leydig) cells. Morphometrically, the thickness of seminiferous tubul
Objective: To investigate occur the histomatrical alternations in placental terminal villi and their vessels of Iraqi diabetes (gestational diabetes and overt diabetes) and normal pregnancies were born male and female neonates. Methods: The hitometrical study of male and female terminal villi of 68 placentae in maternal diabetes mellitus (34 gestational diabetes, 34 overt diabetes (17 DM type 1 and 17 DM type 2) and 34 normal placentae. These placentae obtained from Department of Obstetrics and Gynaecology in three hospitals in Baghdad city. Results: The study showed that there is a statistically significant with higher diameter in central and peripheral sections of the terminal villi and their vessels in m

influencing the biological process of bone healing. Rabbits provide a good animal model for bone healing studies; its bone had Haversian system similar to human.
Material and Methods: Six young locally breaded New Zeeland male rabbits were used in this study, the study conducted in animal house in college of medicine at November and December 2009. Surgical fracture (osteotomy) induced operatively in right ulna under general anesthesia by a hand saw. At the end of fifth weeks, the animals' scarified and the specimens taken
Background: The Titanium and its alloys are suitable for dental implant and medical applications. Biocompatibility of the materials is a major factor in determining the success of the implant and has a great impact on their rate of osseointegration. The aim of this study was to evaluate the biocompatibility and cytotoxicity of Ti2AlC in comparison to CPTi & Ti6Al7Nb in rabbits. Materials and Methods: 10 male New Zealand White rabbits, weighing (2-2.5 kg), aged (10-12 months) were used in this study. Cylindrical implants were prepared from the study materials (CPTi, Ti6Al7Nb and Ti2AlC) with (8mm) height and (3mm) diameter for the evaluation of tissue response and disc specimens were prepared with (6 mm) diameter and (2 mm) thickness for ev

C. acnes causes acne vulgaris most commonly in 12-24 year olds. Five albino rabbits were immunized at day 1 and 14 with Cutibacterium acnes cell free antigen (CFAg) and then infected intradermally with 0.1 ml C. acnes suspension (2×108 cfu/ml) at day 30. Two groups of five infected rabbits were then treated at Day 30 with 0.5% levofloxacin or 0.2% cinnamon oil twice daily for 12 days. Five control rabbits were infected intradermally with 0.1 ml 2×108 cfu/ml Cutibacterium acnes n (2×108 cfu/ml). At day 42, skin test (mm), se
