Honey is an excellent food product with health-giving characteristics. On the other hand, the honey quality can change based on various factors. Physicochemical experiments intend to investigate the honey quality in four geographic directions of Kurdistan province shelf-life and the containers the honey is placed in. In this research, totally 96 samples from 4 apiaries in various parts of the province were prepared and maintained in various dishes/containers and various (time) periods at 25.5±3.5 °C. After preparing the samples, some factors including moisture, reducing sugars, sucrose, pH, acidity, the ratio of fructose to glucose, ash, diastase, hydroxyl methyl furfural were evaluated. The result showed the moisture total average, reducing sugars, sucrose, pH, acidity, the ratio of fructose to glucose, and ash were 13.79%, 77.67%, 2.22%, 3.86, and 21.39 of meq/kg, 1.09% and 0.13%, respectively. Qualitative examinations showed, there was the distance in all samples but no HME. With the increase in shelf-life time, metabolites in the ratio of fructose to glucose and acidity increased significantly, but the factors, moisture, pH were reduced significantly (P<0.05). Various containers had no significant impact on physicochemical characteristics of honey. Generally, one can say that the comparison between the obtained amounts with the current standards, quality of the honey samples were standard and favorable. According to the results of this study, honey can remain at room temperature in different containers for 9 months and maintain anacceptable quality.

Rumen health in ruminants has a great importance because its function has a great deal with milk, meat and fetus production. Many factors can affect the rumen health and destruct its function and performance. this research investigates histopathology lesions resulted from ruminants in the sheep. for this purpose, macroscopic examination in 1562 rumens of the slaughtered sheep Sanandaj was done. Among these, 23 rumens has lesions placed in drums of formalin 10% for macroscopic evaluations by means of Hematoxylin and Eosin coloring were referred into the pathobiology lab. in Macroscopic observations, swelling (65.22%), swelling and focal congestion (30.43%) and looming papillary (4.35%) were detected. The highest microscopic signs in the rumen lesions included: sub mucosal edema (32.69%), ruminate eosinophilic (23.07%), parakeratosis (13.46%), granulomatous ruminate (7.69%), watery degeneration and acute purulent ruminate (5.76%). pathologic lesions of rumen can be due to hyperplasia change in the result of mechanical agitation, stress, parasitic diseases, and mature woody forage.

This study was to determine biomechanical property and radiography of autogenously bone graft covered with Nano hydroxyapatite in the defect of radial bone in rabbit.

Eighteen adult male New Zealand white rabbits were used which were divided into three groups of six rabbits each. A segmental bone defect of 10 mm in length was created in radial shaft. The defects in group I were left as such without filler, whereas in group II the defect were filled up with harvested 10 mm rib, bone and in group III the defect were packed with rib bone covered with nano-hydroxyapatite. The animals were examined by radiography, and the load bearing index were measured at the end of examin.

On the radiographs, bone repair in Group I was not as perfect as those in Group II samples and trace of internal callus filled the gap incompletely in 60 days in Group I. Radiographs obtained in the experimental group showed that the radiopacity of scaffold used in gap was non-uniform but so that non-uniformity in the three months after surgery decreased gradually. Repair defect in Group A and Group B the same group showed no significant difference. The load bearing of group II, III compared with group demonstrated a different significant (P<0.05).

Implantation of autologous graft covered with hydroxyapatite indicated to have positive effect in integral formation of qualitative callus at the site of fracture and early re-organization of callus to regain mechanical strength too.
