| Abstract: Seed companies are looking for promising, quick and effective alternatives to determine the physiological quality of seeds. The objective of the current work was to study the efficiency of the exudate - phenolphthalein pH test to evaluate the seeds of two lots of Libidibia ferrea (Mart. ex Tul.) L. P. Queiroz var. ferrea. The statistical design for the the exudate - phenolphthalein pH test was completely randomized with four replicates of 50 seeds in a factorial design (2 x 5), two seed lots and five soaking periods (30, 60, 90, 120, and 150 minutes), respectively, using two constant temperatures (25 and 30°C). The percentage of viability and germination of the seeds did not differ in the temperatures of 25 and 30°C and in the soaking periods by... |

| It is generally accepted that the formation of otolith microstructures (L- and D-zones) and in particular the organic and mineral fractions vary on a daily basis. Raman microspectrometry provides a nondestructive technique that can be used to provide structural information on organic and mineral compounds. We applied it to thin otolith sections of hake in order to address the following issues: (1) the simultaneous characterization of variations in the organic and mineral fractions both in the core area and along successive otolith microstructures; (2) elucidation of significant differences between these fractions; (3) quantification of the effects of etching and staining protocols on otolith structures. The primordium appeared as a punctual area depicting... |

| This study describes the preparation and use of Roselle (Hibiscus sábddariffa) for the differential staining of testicular tissue sections to find out its staining effect on nuclear, cytoplasmic and other structures. Various treatments using modifications of the plant extract in water were carried out on sections of the rabbit testis. Various levéis of differentiation of nuclear and cytoplasmic structures as well as other structures of this organ was obtained especially when 1% eosin was applied as a counter stain. The best staining result was obtained when iron alum was used to mordant the extract and when the extract, mordanted with potassium alum was acidified using acetic acid and used to stain the sections. Modification of the aqueous extract to an... |

| Although many methods are investigated, cadavers have unique role for education of gross anatomy. This study was performed to make cadaveric based gross anatomy more enjoyable and decrease the time needed for achievement of arterial system for teachers and learners. The adult rabbits in control (n=3) and experimental groups (n=9) sacrificed following deep anesthesia. The samples were fixed by injection of fixative solution to the left ventricle and the corps dropped to the traditional fixative liquid for at least 1 month. The injected fixative solution of experimental group contained stained human red blood cells. The red blood cells stained by eosin (0.25% in saline) for 30 minutes and injected between two injections of fixative. After passing the period... |
