Abstract
Previously, we have used the biochemical receptor binding method to investigate whether down-regulation of the opioid receptor is a mechanism for morphine tolerance, and we were led to a negative conclusion. In the current study, we further used immunohistochemistry to reinvestigate this issue. Male Sprague-Dawley rats (250-300 g) were chronically treated with morphine s.c. for 2, 4 or 6 days, using an escalating dosage paradigm (5-45 mg), which resulted in a 1.8 to 4.0-fold increase in AD50. Rat brains were removed, frozen, coronally sectioned (14 microm) and processed for mu- or delta-opioid receptor immunohistochemistry using the Avidin-Biotin Complex (ABC) method. No significant decrease in mu-opioid receptor (MOR) immunodensity was found in most of the brain regions, which were enriched with MOR after chronic treatment with morphine except for the anteroventral thalamic nucleus in the ventrolateral part (AVVL). No significant change in delta-opioid receptor (DOR) immunodensity after chronic treatment with morphine was found either. Therefore, our conclusion is that down regulation of opioid receptors may not be an important mechanism for morphine tolerance.

Abstract
A field trial to evaluate the efficacy of an oral vaccinia-rabies glycoprotein recombinant virus vaccine in controlling epidemic raccoon (Procyon lotor) rabies was conducted by distributing 180,816 doses (10(8.2)TCID50/ml) of vaccine in wax ampules within fish-meal polymer baits at a rate of 64 doses/km2/treatment throughout a 552 km2 area, forming an 18 km wide band across the northern Cape May Peninsula of New Jersey (USA). Vaccination treatments were conducted in the spring and fall between May 1992 and October 1994 from a helicopter along ecotones and from motor vehicles along roads. Vaccine-laden baits were removed by animals from tracking stations within 3 wk and 61% of the identifiable tracks were those of raccoons. Tetracycline incorporated in the baits as a biomarker was detected in 155 (73%) of the vaccination area raccoons following the fall 1993 and spring 1994 vaccinations. Eleven (61%) of the raccoons sampled in the same time period seroconverted (> or = 0.5 IU) in response to rabies virus glycoprotein. A raccoon diagnosed with rabies from the northern border of the vaccination area on 30 April 1993 provided the first evidence that the barrier was being challenged by the rabies epidemic. The prevalence of rabies in raccoons from the vaccination area for the first year (10%, n = 96) and second year (8%, n = 61) of challenge was reduced more than six-fold by vaccination compared to unvaccinated raccoons from northern adjacent surveillance areas during the corresponding first (65%, n = 189) and second years (53%, n = 43). Vaccination also effectively reduced by three-fold the rate at which the epidemic moved through the raccoon population (15 km/yr). The breach of the vaccination area resulted in a resumption of the high rate (43 km/yr) of epidemic movement and a significant nine-fold increase in rabies prevalence (77%, n = 47). The maximum linear movement (12.9 km) among five ear-tagged rabid raccoons in the study area was significantly greater than that of 19 normal radio-collared raccoons (2.58 km) in the area. These large movements of rabid raccoons, together with relocation of nuisance raccoons, spillover of raccoon rabies in skunks (Mephitis mephitis) and other species, insufficient funding and a decision to discontinue the program in 1994 (which could have resulted in insufficient population immunity among raccoons in the vaccination area) may have contributed to the eventual breach of the barrier.

Abstract
With the emergence of raccoons (Procyon lotor) as the primary rabies reservoir in the United States of America, a recombinant vaccinia-rabies glycoprotein (V-RG) virus vaccine was developed that protected raccoons by the oral route from rabies infection. Despite extensive laboratory evaluation, vaccine safety concerns remained about free-choice distribution for wildlife rabies control. In this study, the oral innocuity of V-RG virus was demonstrated in immunodeficient mice but parenteral exposure resulted in systemic and progressive infection, albeit significantly abrogated in severity in comparison to vaccinia virus. Treatment with vaccinia immune globulin and hydroxyphosphonylmethoxy-propyl-cytosine resulted in significantly longer survival and minimized V-RG viral gross lesions.

Abstract
During the field safety evaluation of a vaccinia-rabies glycoprotein recombinant virus vaccine for wildlife, two biomarkers were used to identify potential contact with vaccine-laden baits. Tetracycline, a commonly used and reliable calciphilic tissue marker, was included in a fish-meal polymer bait matrix and was evaluated from post-mortem bone samples. Additionally, an ante-mortem marker was needed to identify, for prospective study, raccoons which had contacted baits and thus, potentially, vaccine. Sulfadimethoxine (SDM) was included in an attractant slurry surrounding the bait, as a novel short-term seromarker. Preliminary laboratory studies in raccoons demonstrated SDM residues for up to one week following ingestion of a single 250 mg dose. During the first six days after bait distribution, 49 individual raccoons were live-trapped in the vaccination area. SDM was detectable in 38 of 49 (77.5%) serum samples. Similarly, 47 of 56 (83.9%) bone samples from raccoons collected in the vaccination area throughout the twelve-month study were tetracycline-positive. Conversely, none of the serum samples (n = 12) from the first six days of the trial nor any of the bone samples (n = 34) from raccoons in the surveillance area were biomarker-positive.

Abstract
Successful field oral vaccination and protection against viral diseases have so far been achieved only with live-attenuated or live-recombinant virus vaccines. In this communication, we present data that demonstrate that a glycoprotein derived from recombinant baculovirus-infected insect cells is efficacious as an oral vaccine. The glycoprotein (G) of rabies virus (Evelyn Rokitnicki Abelseth strain) was abundantly expressed in a baculovirus expression system and oral vaccination of racoons with the baculovirus-expressed G protein resulted in the production of rabies virus-neutralizing antibodies and protection against a lethal challenge with a street rabies virus. The potential for using the baculovirus-expressed G protein for oral immunization of wildlife is discussed.

Abstract
We have mapped a linear epitope recognized by the virus-neutralizing monoclonal antibody 6-15C4 within the primary sequence of the G protein from the Evelyn-Rokitnicki-Abelseth strain of rabies virus. This was accomplished by using fragments of the rabies virus G protein and deduced amino acid sequences of neutralization-resistant variant rabies viruses. The monoclonal antibody 6-15C4 specifically recognized a synthetic peptide (peptide G5-24) which resembles the 6-15C4 epitope in structure. In addition, a tandem peptide constructed from the G5-24 peptide and a dominant TH cell epitope of the rabies virus N protein induced protective immunity against lethal rabies virus challenge infection in mice.

Abstract
Immunization of mice and hamsters with a cocktail of mouse MAbs specific for rabies virus nucleocapsid protein and glycoprotein protected animals not only when challenged with a lethal dose of rabies virus after immunization, but also in post-exposure situations. Hamsters treated with the MAb cocktail 3 h after virus inoculation were completely protected from lethal rabies virus infection, and 80% of the animals survived when the MAb cocktail was given 36 h after virus challenge. The potential usefulness of this MAb cocktail for the postexposure treatment of human rabies is discussed.
