amiodarone is used in treatment of cardiac arrhythmias. therapeutic use of amiodarone is limited by its side effects, including pulmonary toxicity. human placenta extract (hpe) contains a variety of bio-active substances. thus, the present study aimed to quantitatively evaluate the protective effects of hpe on the structural lung changes induced by amiodarone using stereological methods. spragu...

objective: to determine the effects of topical administration of 20% oltipraz solution on histomorphometrical and stereological aspects of skin tissue in full thickness skin wounds in laboratory rats. methods: thirty-six male wistar portion rats (220±20 g) were randomly divided into three groups (n=12). on the first day of experimentation, a 1-cm 2 circular wound was made on the posterior surfa...

When properly applied, stereology is a very robust and efficient method to quantify a variety of parameters from biological material. A common sampling strategy in stereology is systematic random sampling, which involves choosing a random sampling [corrected] start point outside the structure of interest, and sampling relevant objects at [corrected] sites that are placed at pre-determined, equi...

Objective—The effects of vasectomy on testes and related structures are disputable. The aim of this study was to determine whether the reproductive organs of rabbits were influenced after 12 months vasectomy. Study design—Bilateral vasectomy was performed on 10 male adult New Zealand Big Eared White Rabbits (another 10 rabbits set as sham operated group) and tissue samples were examined by ligh...

Thermo-deformable plastic films experience an optical birefringence phenomenon when they are subjected to mechanical strain, this phenomenon can be described by color fringes behavior observed in sequences of images acquired through photoelasticity assemblies. This paper proposes a temporary morphological analysis that color fringes experience when the plastic film is deformed. For the image an...
