A 36-year-old man presented with sudden onset of hemorrhagic cerebral infarction in association with polycythemia vera. On admission this patient manifested semicomatous state and left hemiplegia which were gradually progressed. X ray CT demonstrated a severe hemorrhagic infarction in right MCA territory accompanying marked shift of midline structures. Cerebral angiograms represented occlusion of right MCA showing floating emboli in the internal carotid. Hematocrit value was found to be high as 61.2 per cent. Elevated ICP levels were noted by means of epidural pressure monitoring. Deterioration of patient status was considered to be based on impairment of cerebral circulation due to hemostasis by elevated blood viscosity. In addition to administration of mannitol solution, intermittent exsanguinations, 1000 ml in total amount, were performed and hematocrit levels were corrected by hemodilution. Consciousness level was remarkably improved in accordance with reduction of ICP, which well corresponded to values of hematocrit. Level of ICP and tissue perfusion are convinced to be strongly affected by hemorheological factor in the state of raised ICP.

Feline herpesvirus 1 (FHV-1) is an important viral pathogen of cats. Like other alphaherpesviruses, FHV-1 contains a HSV-1 glycoprotein B (gB) homolog. In this study, monospecific antisera to HSV-1 gB reacted with three FHV-1 proteins (100, 64, and 58 kDa) present in virion lysates by immunoprecipitation and immunoblot analyses. Reduced stringency hybridization experiments using a HSV-1 gB probe localized the FHV-1 gB gene to a 9.6-kb Sa/l fragment in the unique long region of the genome. Northern blot analyses further localized the entire coding region within a 3.3-kb SacI fragment. The nucleotide sequence of this fragment was determined and two overlapping open reading frames (ORFs) encoding gB and ICP 18.5 were predicted. The amino acid sequence of the 2829 bp gB ORF was shown to have a high degree of homology with gB analogs of HSV-1, EHV-1, BHV-1, EHV-4, and especially PRV. Two unique characteristics of gB of FHV-1 were the unusually long signal sequence of 73 residues and two potential internal cleavage sites, RTRRS and RSRRS. An evolutionary tree based on gB homologs from 12 alphaherpesviruses suggests that feline herpesvirus-1 evolved along similar lines as the varicelloviruses, pseudorabies virus, bovine herpesvirus type 1, and equine herpesvirus types 1 and 4. The gB gene of FHV-1 was expressed in vaccinia virus (WR). This recombinant induced fairly high titers of virus neutralizing antibodies in rabbits. In Western blot analyses with potassium tartrate-purified virions, a 60-kDa polypeptide reacted with the rabbit antisera.
