BACKGROUND: Honey is an excellent food product with health-giving characteristics. On the other hand, the honey quality can change based on various factors. OBJECTIVES: 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. METHODS: 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. RESULTS: 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. CONCLUSIONS: 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.

Effects of furosemide, exercise, and atropine on tracheal mucus transport rate (TMTR) in horses were investigated. Atropine (0.02 mg/kg of body weight) administered IV or by aerosolization significantly (P < 0.05) decreased TMTR at 60, but not at 30 minutes after its administration in standing horses. Furosemide (1.0 mg/kg, IV) did not have any significant effect on TMTR when measured at 2 or 4 hours after its administration in standing horses. Exercise alone or furosemide (1.0 mg/kg, IV) administration followed 4 hours later by exercise did not alter TMTR, compared with values for standing control or exercised horses administered saline solution. Atropine (0.02 mg/kg, IV) administered after exercise significantly (P < 0.05) decreased TMTR, compared with values for no exercise standing controls, for exercise after administration of saline solution, and for furosemide and exercise.

Effects of temperature and storage time on canine bone-transfixation pin specimens were tested by comparing pin pull-out forces. A total of 16 femurs from 8 mature dogs were tested. Five nonthreaded Steinmann pins were placed through both cortices in the diaphysis of each femur. The femurs were then sectioned transversely between each pin, with a bonepin specimen placed evenly into each of 5 groups prior to biomechanical testing. Four bone-pin specimen groups were stored at -20 or -70 C for 14 or 28 days, while 1 specimen group was immediately tested. Pull-out forces for frozen groups were compared with pull-out forces for the fresh group. Using two-way ANOVA, there was no statistical difference in mean axial-extraction forces among bonepin specimen in any of the tested groups. It is concluded that acute pin pull-out forces are not significantly affected by freezing temperature or time. However, specimens stored at -20 C for as few as 14 days had a trend for increased pull-out forces, compared with freshly harvested specimens. Therefore, the authors recommend storage of bone-pin specimens at -70 C when possible.

To investigate the effects of T-2 toxin on the blastogenesis of lymphocytes, pathology, hemogram and blood chemistry in the goat, the Korean native goats were treated orally with T-2 toxin for 21 days with a dosage of 0.6mg per kg body weight. The total count of leukocytes and lymphocytes decreased significantly from 14 to 21 days after treatment. Myeloid : erythroid ratios increased significantly on days 12 after treatment Delayed-type hypersensitivity skin reactions to tuberculin were reduced predominantly. T-2 toxin induced prolonged prothrombin time. Mitogenic responses of lymphocytes to both lipopolysaccharide and phytohemagglutinin were significantly depressed on days 7 and 14 after treatment. Treatment of T-2 toxin caused marked depletion of lymphocytes in the thymus, mesenteric lymph node, Peyer's patches and spleen.

The objective of this study was to evaluate the in vivo predatory viability of the nematophagous fungus, Duddingtonia flagrans, after storage (36 months) and refrigeration (2-8 °C). This viability was evaluated using the infective larvae of gastrointestinal nematodes of sheep in the Northeastern semi-arid region of Brazil. Sixteen Santa Inês sheep with negative counting of eggs per gram of feces (EPG) were divided into four experimental groups, each group comprised of four animals. The pellets were administered at the dose of 3 g/10 kg of live weight (20% fungal micelyum), and a single administration was performed for each animal. Group I was administered pellets that had been stored for 36 months; Group II, freshly produced pellets; Group III, freshly produced pellets that did not contain fungi; and Group IV, pellets were not administered, and this was the control group. Feces were collected for 5 days, every 24 h for analysis. There was a significant decrease in the number of infective larvae of sheep nematodes that received D. flagrans pellets in a sodium alginate matrix, 82% was observed for Group I and 71% for Group II, compared to the control group. It is therefore concluded that the fungus, D. flagrans, pelleted in sodium alginate matrix after 36 months of storage at 2-8 °C, showed efficacy in reducing the number of infective larvae of gastrointestinal nematodes of sheep.
