Commercial oyster fisheries in Alabama have a history of very variable yearly production While oyster landings in the state have been as high as 1 5 million lbs in 1982 during the 1990s yearly landings were as low as 83 530 lbs in 1990 and as high as 1 201 799 lbs in 1992 In the most recent years the variability of the catch continues i e 1 041 332 lbs in 2005 939 599 lbs in 2006 and

Histological Processing of pH

In addition typical tissue processing methods require the use of alcohol and/or xylene for specimen dehydration causing severe distortion of hydrogel morphology The substitution of these chemicals with deionized water during the processing steps also proved to be vital for maintaining hydrogel structure and morphology Slides stained with cresyl violet showed excellent tissue and hydrogel

Dehydrating clearing and embedding

Thus it has been particularly useful in histological preparations of insects and ticks Clearing consists of removal of the dehydrant with a substance that will be miscible with the embedding medium (such as paraffin or paraplast) There are of course many clearing agents available for use in histological preparations This chapter discusses some of the agents of dehydration and clearing

Dehydration was then carried out in ascending grades of alcohol followed by clearing with xylol Impregnation was done in pure soft paraffin for 2 h at 50C followed by embedding in hard paraffin Sections of 3–5 microns in thickness from each block were cut by the microtome then stained with hematoxylin and eosin stain to study the general histological structure

Here I demonstrate simple staining methods that allow high‐contrast imaging of embryonic tissues at histological resolutions using a commercial microCT system Quantitative comparisons of images of chick embryos treated with different contrast agents show that three very simple methods using inorganic iodine and phosphotungstic acid produce overall contrast and differential tissue contrast

HE stain

HE is the combination of two histological stains: hematoxylin and eosin The hematoxylin stains cell nuclei blue and eosin stains the extracellular matrix and cytoplasm pink with other structures taking on different shades hues and combinations of these colors The stain shows the general layout and distribution of cells and provides a general overview of a tissue sample's structure

Effects of prolonged water washing of tissue samples fi xed

After formalin fi xation of histological tissue sam-ples samples traditionally are washed in water to prevent exposure to formalin gas and formalin pol-lution of the ethanol dehydration series A few text books describe the necessity of washing samples in water after fi xation and indicate that this process does not harm the samples (Kingsbury 2007 Luna 1968) Therefore in our laboratories

Dehydration

Dehydration can lead to serious complications including: Heat injury If you don't drink enough fluids when you're exercising vigorously and perspiring heavily you may end up with a heat injury ranging in severity from mild heat cramps to heat exhaustion or potentially life-threatening heatstroke Urinary and kidney problems Prolonged or repeated bouts of dehydration can cause urinary
