Screening of proteins for crystallization under laser irradiation was investigated using six proteins: ribonuclease B, glucose dehydrogenase, lysozyme, sorbitol dehydrogenase, fructose dehydrogenase and myoglobin. Shining 532 nm green circularly polarized laser light with a picosecond pulse and 6 mW power for 30 s on newly set-up protein drops showed a marked improvement in the number of screen conditions amenable for crystal growth compared with control drops under identical conditions but without laser exposure. For glucose dehydrogenase and sorbitol dehydrogenase, larger and better quality crystals were formed and the resolution of X-ray diffraction was improved. The speed of crystallization increased in the case of ribonuclease B, lysozyme and sorbitol dehydrogenase. During laser irradiation, the amount of precipitation in the screened drops increased, indicating a transient decrease in protein solubility. At the optimized laser settings, there was no deleterious effect of the laser on crystal growth or on the protein. In the cases of ribonuclease B and lysozyme the crystal packing did not change owing to the laser exposure.

The serum and hepatic enzymes of rats were studied after exposed to country made liquor (CML) along with two chelating agents (glutathione and Selenium). There was a significant increase in several serum enzyme levels (viz., aspartate transaminase, alanine transaminase, alkaline phosphatase, sorbitol dehydrogenase, glutamate dehydrogenase, bilirubin) and decrease in various hepatic enzymes (Succinic dehydrogenase, Glucose 6-phosphatase, 5'Nucleotiease, Acid phosphatase, Acid ribonuclease, Cytochrome P-450) due to repeated administration of CML (2ml/100g of body weight). Results of this study revealed that the GSH and Se could give a significant protective action in serum and hepatic enzymes of CML exposed rats.
