    Four species of the genus Lagocephalus pufferfish: L. gloveri (“kurosabafugu”), L. wheeleri (“shirosabafugu”), L. inermis (“kanafugu”) and L. lunaris (“dokusabafugu”) were discerned by the comparison of electrophoretic patterns of proteins and of L-Lactate dehydrogenase (LDH, EC 1.1.1.27) isozymes in skeletal muscle and vitreous humor. The proteins of skeletal muscle and vitreous humor were separated by polyacrylamide gel isoelectric focusing (PAG-IEF), and LDH isozymes were separated by agarose gel electrophoresis. The electrophoretograms of proteins of skeletal muscle and vitreous humor were significantly different from each other among the three species except for L. inermis. LDH zymograms in vitreous humor showed species specific patterns among the four species. Furthermore, a puncture of an eye ball of pufferfish enabled us to yield enough amount of sample to obtain the LDH zymograms not to give any damage to the fish. From these results, the comparison of LDH zymograms in vitreous humor is a useful method for distinction of these pufferfishes without making them unmarketable.

    It was accomplished that free bile acids and conjugated bile acids were separated electrophoretically on the cellurose acetate and agarose gel membrane. Separated bile acids were stained by the 3α-hydroxysteroid dehydrogenase/diaphorase/dihormazane system. By this method, the human biles were analyzed and two purple bands were detected. The fast moving band was trihydroxy bile acid group (cholic acid). The slow moving band was dihydroxy bile acid group (deoxycholic and chenodeoxycholic acid). No Lithocholic acid was detected by this system in the human bile.

    Changes in serum proteins in experimental diabetic rats caused by administration of streptozotocin (STZ) were investigated. Rats were administered 60mg/kg STZ and their serum proteins during 3-12 weeks were analyzed using two-dimensional polyacrylamide gel electrophoresis (PAGE) under non-denaturing conditions. Marked increase and decrease in amounts of several proteins were observed after STZ administration. These proteins almost returned to normal when the blood glucose level was controlled for 3 weeks at 100-200mg/dl with insulin. This suggest close relations between these proteins and diabetes.
