  • The proteins of the race horse erythrocyte membrane were analysed by polyacrylamide gel electrophoresis in sodium dodecyl sulfate(SDS-PAGE), and their relations to the fast erythrocyte sedimentation rate(ESR) of the race horse were investigated. The erythrocyte sedimentation rate of race horse were very fast compared with the human one(33 times <$90^{\circ}-plastic-ESR/30m$> and 25 times <$90^{\circ}-micro-ESR/30m$> as fast as the human one) are reported previously. Although the general protein profiles of the race horse erythrocyte membranes were almost similar to that of human, band 3 content was showing higher in race horse (34.7%) than in human (25.3%). The glycoprotein profiles of the race horse erythrocyte membranes revealed by periodic acid Schiff's(PAS) stain showed a marked difference from that of human. The PAS-1(glycophorin) and PAS-2(sialoglycoprotein) present in human erythrocyte memo brane were almost absent from the Holstein and race horse erythrocyte membranes, but PAS-2 was more in only race horse from that of human. Instead, the bovine erythrocyte membranes showed a strong PAS-B near the origin of the electrophorograms and the race horse erythrocyte membranes showed a strong PAS-negative band near the end of the electrophorograms, which is named as PAS-E in this study. These results suggest that the fast sedimentation rate of race horse erythrocyte is due in part to the presence of more band 3 protein fraction and PAS-E glycoproteins in the race horse erythrocytes.

  • The protein of the bovine, horse and dog erythrocyte membrane were analyzed by polyacrylamide gel eletrophoresis in sodium dodecyl sulfate and their relation to the sedimentation rate of animal erythrocytes were investigated by treating the erythrocytes with proteinases such as trypsin and chymotrypsin. Protein content in erythrocyte membrane was in human, in Jindo dog, in cattle and in horse, showing similar in among. The erythrocyte sedimentation rates bovine erythrocytes from Hostein and Korean native cattle were very slow compared with the human one(1/7 as slow as the human one) as reported previously. Although the general protein profiles of the bovine erythrocyte membranes were almost similar to that of human, bovine erythrocyte membranes showed one additional protein band, called band Q in this study, which migrated electrophoretically to the mid-position between band 2 and band 3 in human erythrocyte membranes. The erythrocyte sedimentation of race horse were very fast compared with the human one are reported previously. Although the general protein profiles of the race horse erythrocyte membranes were almost similar to that of human, band 3 content was showing higher in race horse(34.7%) than in human(25.3%). The general protein profile of the Jindo dog erythrocyte membrane was almost similar to the human patterns, Jindo dog erythrocyte membranes showed one absent protein band. It was band 7. The glycoprotein profiles of the bovine erythrocyte membranes revealed by periodic acid-Schiff(PAS) stain showed a marked difference from that of human. The PAS-1(glycophorin) and PAS-2(sialoglycoprotein) present in human erythrocyte membrane were almost absent from the bovine erythrocyte membranes showed a strong PAS-positive band near the origin of the electraphorograms, which is named as PAS-B in this study. The PAS-1 and PAS-2 present in human erythrocyte membrane were almost absent from race horse erythrocyte membranes, but PAS-2 was more in only race horse from that of human. The PAS-1 and PAS-2 were absolutely absent from the Jindo dog erythrocyte membrane. These results suggest the slow sedimentation rate of bovine erythrocytes is due in part to the presence of band Q protein fraction and PAS-B glycoprotein in the bovine erythrocytes, and that the fast sedimentation rate of race horse erythrocyte is due in part to the presence of more band 3 protein fraction and PAS-E glycoproteins in the race horse erythrocytes.

  • Equine coital exanthema caused by equine herpesvirus type 3 (EHV-3) is a venereal disease which seriously drops horse reproduction rates. Here, we isolated EHV-3 from infected horses and investigated their biological characteristics. Initial cytopathic effects such as rounding of cells were detected 48 hours post infection of the virus into RK-13 cells. The infected cells were going to detach from the surface of culture flasks 72 hours post infection. The type of isolated viruses from swabbed samples was EHV-3 by PCR analysis. Glycoprotein G (gG) of isolated EHV-3 has a 99.25 percent similarity rate to that of EHV-3 334/74 control strain. The isolated EHV-3 was named Georo strain. Georo strain consisted of four major proteins including 145 kD, 60 kD, 45 kD and 40 kD, as shown by SDS-PAGE analysis. We hope the newly isolated Georo strain of EHV-3 can be used for studying various aspects of Korean equine coital exanthema.
