The repair of peripheral nerve injuries is still one of the most challenging tasks and concerns in neurosurgery. Effect of methylprednisolone-laden hydrogel loaded into a chitosan conduit on the functional recovery of peripheral nerve using a rat sciatic nerve regeneration model was assessed. A 10-mm sciatic nerve defect was bridged using a chitosan conduit (CHIT/CGP-Hydrogel) filled with CGP-h...

morphometric differentiations may explain biogeographic distinctions among populations of a given species. the possibility of morphometric distinctions between two populations of eurygaster maura l. collected from the northeast (golestan province) and the northwest (azarbayejan province) of iran was examined using principal component analysis over 25 body measurements (eight absolute and 17 pro...

Objective-Effect of local administration of laminin and fibronectin on nerve regeneration was assessed. Design- Experimental study. Animal- Sixty male Wistar rats. Procedures- The animals were divided into four experimental groups (n=15), randomly: In transected group left sciatic nerve was transected and stumps were fixed in adjacent muscle. In treatment group (CHIT/LF) the defect was bridg...

The assessment of the indicators reproductive potential male white rats exposed to smoke for 1 month was carried out. Examination animals included determination spermatogenesis index and level DNA fragmentation methylation in testes blood. A statistically signifi-cant increase genome-wide blood revealed. morphometric study testis tissue revealed a violation indices rats.

background: gonadotropin-releasing hormone (gnrh) is a reproductive key hormone. the gnrh analogues are widely used in in vitro fertilization and treatment of sex hormone-depended cancers induced by the materials used in chemotherapeutic agents. objective: the aim of this study is to evaluate the effects of cyclophosphamide and decapeptyl (analogues of gnrh) on histomorphometry and stereology o...

objective: to assess the neuroprotective effects of local administration of 17- beta- estradiol on nerve regeneration. methods: sixty female wistar rats were overiectomized and divided into four experimental groups (n = 15), randomly: in autograft group a segment of sciatic nerve was transected and re-implanted reversely. in sham-surgery group sciatic nerve was exposed and manipulated. in trans...

The postnatal development of rat sublingual glands was analyzed by morphometric and radioautographic studies. The absolute number of each cell type was evaluated by the Aherne II morphometric method for cell counting and labeling indices of these cell types were determined in radioautographs from animals injected with 3H-thymidine. The quantitative cell population kinetic studies were accompani...

The aim of the study was to evaluate the importance of lakes in the Wielkopolska region (western Poland) to migratory waterbirds on the basis of lake morphometry. Single bird surveys were conducted on 204 lakes in November between 1973–1975 and 1984–1986. The observed species distribution deviated from the model of random placement. The relationship between habitat variables and “avian indices”...

The presence of fat stores in fish is widely used as a correlate of fish health and fitness. Techniques to measure fat content with some accuracy are available for medium-sized and large fish, but apart from morphometric indices, a noninvasive method to determine fat content in small fish has hitherto been lacking. In this study, we introduce a novel method to measure the fat content in live fi...
