Abstract
Retrospective surveillance study of clostridial infections of cattle in Zambia, for the period 1985 to 1994, showed that out of the 318 cases observed, 62.8% and 24.2% were from Western and Southern provinces, respectively. Of the 6 clostridia species identified, Clostridium septicum (38.1%) followed by C. chauvoei (36.2%) and C. perfringens (13.2%) were dominant. Although the highest incidence for clostridial infections was in 1989 (75 cases) and 1990 (77 cases), the number of C. perfringens cases seemed to increase. More cases were found in the dry season until the onset of the rains, that is, the period August to December.

Abstract
To obtain further information on the latent infection with bovine herpesvirus 1 (BHV-1) in the natural host, we examined the nasal secretions and various tissues of experimentally infected calves using virus isolation, polymerase chain reaction (PCR), and immuno-PCR/antigen (Immuno-PCR/Ag) assays. In the nasal secretions, viral DNA was detected in samples with virus isolation titers of 10(4.3) TCID50 or more by PCR. On the same samples, Immuno-PCR/Ag remained positive up to day 19 p.i. the last day of test. BHV-1 DNA was detected from the following tissues in all the calves at day 22 p.i.: trigeminal ganglia, ovaries, lungs, nasal and tracheal mucosae, spleen, prescapular and precrural lymph nodes, and peripheral blood leukocytes (PBL), but not skeletal muscles. Virus was not recovered from any of these tissues. The present findings suggest a possible role of leukocytes in BHV-1 latent infection.

Abstract
Pseudorabies rabies (PrV) replication in Vero cells was suppressed by treatment with human natural interferon-alpha (IFN-alpha). Messenger RNA transcribed from the PrV immediate-early (IE) gene was reduced in the IFN-alpha-treated cells. Transient expression assays showed that transcription from the PrV IE promoter was selectively inhibited in the IFN-alpha-treated cells. Analysis of deletion mutants of the PrV IE promoter sequence suggested that at least one element between the transcription initiation site (+1) and -90 in the PrV IE promoter was concerned with the negative regulation.

Abstract
gammadelta T cell populations are known to expand in response to intracellular bacterial infectious agents regardless of previous priming. We have shown previously that soluble factor(s) produced by Mycobacterium-stimulated monocytes activate cord blood gammadelta T cells to proliferate. In this study, we investigated whether cytokines produced by monocytes are responsible for gammadelta T cell activation in vitro: interleukin (IL)-1beta, IL-6, IL-8, IL-12, tumor necrosis factor (TNF)-alpha and granulocyte/macrophage colony-stimulating factor were examined. Recombinant human IL-12 stimulated gammadelta T cells, but not alphabeta T cells in peripheral blood mononuclear cells, to express CD25 on their surfaces, and to expand in number in vitro. IL-12-primed gammadelta T cell numbers increased to a greater extent in the culture to which exogenous IL-2 (5 U/ml) was added. Anti-TNF-alpha monoclonal antibody inhibited IL-12-induced up-regulation of CD25 on gammadelta T cells, suggesting that endogenous TNF-alpha may play a role in IL-12-induced activation of gammadelta T cells. Recombinant TNF-alpha synergistically augmented IL-12-induced activation of gammadelta T cells. Furthermore, IL-12 up-regulated TNF receptors on gammadelta T cells in vitro: TNF-alpha binding to its receptor induced CD25 expression on the gammadelta T cells in an autocrine or paracrine fashion, or perhaps both. It also became evident that both IL-12 and TNF-alpha were produced by mycobacterial lysate-stimulated monocytes. Taken together, these results suggest that upon confrontation with mycobacterial organisms, gammadelta T cells can be quickly and antigen-nonspecifically activated by soluble factors including IL-12 and TNF-alpha, both of which are produced by mononuclear phagocytes in response to mycobacterial organisms.

Abstract
The deduced amino acid sequence at the hemagglutinin (HA) cleavage site of 76 avian influenza (AI) viruses, subtypes H5 and H7, was determined by reverse transcription-polymerase chain reaction and cycle sequencing techniques to assess pathogenicity. Eighteen of the 76 viruses were isolated in 1993 and 1994 from various sources in the United States. In addition, 34 H5 (4 highly pathogenic [HP] and 30 non-highly pathogenic [non-HP]) and 24 H7 (3 HP and 21 non-HP) repository viruses, isolated between 1927 and 1992, were sequenced and the sequences compared to those in recent isolates. All repository HP H5 and H7 viruses studied had multiple basic amino acids adjacent to the HA cleavage site and most had basic amino acids in excess of the proposed minimum motif B-X-B-R (B = basic amino acids arginine or lysine, X = nonbasic amino acid, R = arginine) that has been associated with high pathogenicity. Of the non-HP viruses studied, 35 of 38 for H5 and 30 of 31 for H7 conformed to the motif B-X-X-R and B-X-R, respectively. Two non-HP H5 viruses had the motif X-X-X-R at the cleavage site and a third had the motif B-X-X-K (K = basic amino acid lysine). One non-HP H7 (A/Pekin robin/CA/30412-5/94) had four basic amino acids (K-R-R-R) adjacent to the cleavage site. Although the Pekin robin isolate did not produce disease in chickens under the conditions of the study it did have the amino acid sequence compatible with that in HP AI viruses and, therefore, is considered potentially HP. This is the first account of an H7 virus that is non-HP in chickens but meets the molecular criterion to be classified as HP.

Abstract
BACKGROUND & AIMS The chromosome region 18q21 has been shown to be frequently deleted in colorectal cancers, and such frequent allelic loss is a hallmark of the presence of a tumor-suppressor gene. The DPC4 gene, which is located at 18q21, has been identified as a tumor-suppressor gene from examination of pancreatic cancers. The aim of the present study was to determine if it might also be altered in colorectal cancers. METHODS Mutation analyses of the DPC4 gene were performed on complementary DNA samples from 31 primary colorectal cancer specimens using a combination of polymerase chain reaction, single-strand conformation polymorphism, and DNA sequencing. RESULTS Four missense mutations producing amino acid substitutions and a somatic 12-base pair deletion in the coding region of the DPC4 gene were detected in the 31 cancers (16%; 5 of 31). CONCLUSIONS The DPC4 gene may play a role as a tumor-suppressor gene in a fraction of colorectal cancers; however, while allelic loss at 18q21 is very often seen in colorectal cancers, only a minority show DPC4 mutations, suggesting that there might be another tumor-suppressor gene in this chromosome region.

Abstract
Liposomes containing polyethylene glycol-derivatized phospholipids are able to evade the reticuloendothelial system and thereby remain in circulation for prolonged periods. We report here that doxorubicin encapsulated in these sterically stabilized liposomes (S-DOX) suppresses the growth of established human lung tumor xenografts in severe combined immunodeficient (SCID) mice and inhibits the spontaneous metastases of these tumors. The enhanced therapeutic efficacy of S-DOX compared to free doxorubicin was demonstrated in two independent human/mouse models. In the first model, S-DOX inhibited the growth of a human non-small cell lung tumor xenograft established orthotopically in the lungs of SCID mice. Treatment of these mice with S-DOX, but not with free drug, suppressed the growth of the tumor in the lung, prevented metastasis from the lung, and enhanced survival percentage. In another model, the human lung tumor is engrafted into gonadal fat pad of SCID mice. Human tumor xenografts grow floridly in this site of engraftment, and the tumor spreads from this primary site into the peritoneal cavity and subsequently reaches the liver and lung. In this model, free drug suppressed the growth of the primary tumor but had no effect upon the subsequent spread of the tumor into the peritoneal cavity, liver, and lung. In contrast, treatment of the tumor-bearing mice with S-DOX (but not with doxorubicin in conventional liposomes) suppressed the tumor spread to the peritoneal cavity, completely arrested metastasis to the liver and lung, and suppressed the growth of the primary tumor xenograft. This report provides the first evidence that antitumor drugs delivered by sterically stabilized liposomes can arrest the metastasis of human tumor xenografts.

Abstract
This review is to provide information on viral diseases of livestock in Zambia. The distribution of the diseases as well as the control measures and limited research that has been done, are described. Foot and mouth disease (FMD) causes serious economic losses in the cattle industry. So far five serotypes (SAT1, SAT2, SAT3, O and At of FMD virus have been isolated in Zambia. Other notifiable viral diseases are rabies, Rift Valley fever, Lumpy skin disease, African horse sickness, bluetongue, African swine fever, Newcastle disease, Marek's disease, fowlpox and infectious bursal disease. Based on the reports of clinical and/or serological diagnoses, these are widespread in the country, although their precise incidence rates are not known. With the establishment of a veterinary school equipped with modern diagnostic facilities and the increasing number of qualified veterinary personnel, this review would stimulate surveillance study on the viral diseases for the ultimate goal of achieving effective disease control measures.

Abstract
Previously we reported that human imunocompetent cells engrafted into scid mice mount a sustained and vigorous humoral immune response to murine erythrocytes. One of the dominant and consistently observed reactivity pattern of these antibodies in immunoblot analysis is with the alpha and beta isoforms of spectrin. In order to define the human xenoreactive response more completely, a hybridoma was generated (from a hu-PBL-scid mouse) whose antibody reacted with two high molecular weight species 225 to 250 kDa. We report here that this conserved antibody species reacts with both the murine and human erythrocyte proteins and cDNA nucleotide sequence analysis of the light and heavy chain genes encoding this antibody reveals that the light chain variable region gene has been previously observed in association with an autoreactive antibody. In addition to characterizing a conserved human B cell clonotype this is the first report of a human monoclonal antibody being generated from the hu-PBL-scid model using the standard hybridoma technology.

Abstract
Pseudorabies virus (PRV) early protein 0 (EP0) is a transactivator containing the RING finger domain. Analysis of transactivating activity of truncated forms of the EP0 molecule consisting of 410 amino acids revealed that amino-terminal region containing the RING finger domain, amino acids 1 to 84, and the region between amino acids 114 to 242 containing acidic amino acid sequences were required for the transactivation. On the other hand, the mutant consisting of amino acids 1 to 113 exhibited a dominant-negative property.

Abstract
Intranasal vaccination of chickens with inactivated Newcastle disease virus (NDV) induced both local and systemic antibody responses, resulting in protection against intranasal challenge with a lethal dose of a virulent NDV strain. The immune response was enhanced by the use of cholera toxin B subunit (CTB) as an adjuvant and only small amounts of the challenge virus were recovered from the birds vaccinated together with CTB. On the other hand, subcutaneous vaccination with the same antigen induced only a serum antibody response in chickens, allowing the challenge virus to replicate in the sinus. The present results indicate that secretory antibodies induced on the respiratory mucosal surface by intranasal vaccination with inactivated NDV protected chickens from lethal infection by inhibiting virus replication at the portal of entry for the virus.

Abstract
We report here the placement of nondisrupted 1-mm3 pieces of fresh human lung tumor biopsy tissue into the subcutis of severe combined immunodeficient (SCID) mice results in the engraftment of tumor-infiltrating leukocytes (TIL) in all but 5 of 148 mice inoculated with 39 different biopsy tissue specimens. In mice coengrafted with tumor and TIL the normal histologic architecture of the tumor and TIL interface was maintained for up to 22 wk. The TIL in the xenograft were shown to divide and were maintained exclusively at the site of tumor inoculation. It is established here that plasma cells in the TIL population produce Abs that react in western blots with tumor cell lysates. These Abs were shown to react with high and low m.w. proteins derived from both the membrane and cytosolic fractions of tumor cell lysates. The production of human Ig was found to be T cell dependent, and immunohistochemistry and in situ hybridization of DNA, using a human-specific cDNA probe, established the human identity of the tumor and TIL. High levels of human Ig in the sera of mice inoculated with tumor biopsy tissue are associated with the growth arrest of adenocarcinoma xenografts. Our results establish the co-engraftment of human tumors and TIL into SCID mice as new animal model with which to evaluate TIL function and novel therapeutic strategies that are designed to augment TIL anti-tumor activity.

Abstract
A 51-year-old male was admitted to our hospital because of diabetic ketoacidosis. His symptoms were promptly improved with intensive insulin therapy, but his plasma glucagon immunoreactivity measured by the OAL-123 radioimmunoassay (RIA) system showed persistently high values (3,090-3,210 pg/ml). A computed tomographic scan, abdominal angiography and endoscopic examination of his gastrointestinal tract showed no evidence of glucagonoma. After removing the immunoglobulin fraction from the plasma, his immunoreactive plasma glucagon level returned to normal. Moreover, the immunoglobulin G fraction purified from the patient's plasma inhibited the binding of [125I]glucagon to rabbit antiglucagon antiserum, OAL-123. Dot-blot analysis demonstrated that the immunoglobulin G of this patient cross-reacted against OAL-123. Therefore, it was considered that the prominent hyperglucagonemia in this patient was due to the presence of IgG, which interfered with the measurement of plasma-immunoreactive glucagon.

Abstract
Three strains of influenza A virus (H3N2) were isolated from pigs in Hokkaido, Japan in 1993. The hemagglutinin (HA) antigen of the three isolates was related to that of recent H3N2 viruses of human origin. The reactivity patterns of two of the isolates (A/sw/Obihiro/1/93 and A/sw/Obihiro/2/93) with monoclonal antibodies to the hemagglutinin of A/Bangkok/1/79 strain were similar to that of the human H3N2 strain isolated in Hokkaido in 1988, while that of the other one (A/sw/Obihiro/3/93) was similar to human H3N2 strains of 1993. In the phylogenetic analysis based on the nucleotide sequences of the HA1 regions, the HA genes of the two isolates were shown to be closely related to those of human H3N2 viruses isolated between 1986 and 1988. The remaining one isolate was shown to be closely related to those of current human H3N2 viruses. We have also found serological evidence that the A/sw/Obihiro/1/93 virus is circulating extensively in Obihiro swine. It is clear from these findings that pigs were infected with the recent H3N2 influenza virus during the human epidemic and that the virus has been maintained in pigs for at least five years.

Abstract
Pseudorabies virus (PRV) early protein 0 (EP0) contains the RING finger domain with homology to the immediate-early (IE) protein ICP0 of herpes simplex virus type 1 (HSV-1). EP0 was detected by indirect immunofluorescence in the nuclei of the cells transfected with EP0 expression plasmid as is the case in cells infected with PRV. In transient expression assays, EP0 transactivated the PRV IE, thymidine kinase (TK) and glycoprotein X (gX) promoters, indicating that EP0, like ICP0 of HSV-1, is a transactivating protein.

Abstract
The immediate-early protein (IE180) of pseudorabies virus (PrV) is localized predominantly in the nuclei of infected cells. To define the nuclear localization signals within IE180, we prepared truncated mutants of IE180 and analyzed their localization in the transfected cells by indirect immunofluorescence. Analysis of mutants truncated from the carboxy-terminal end of the 1460-amino acid polypeptide showed that two regions including a short sequence of basic amino acid residues were associated with the nuclear localization of IE180. To assess whether these regions substantially function as signals for nuclear localization of the IE180 molecule, we then constructed two deletion mutants lacking each region. A mutant lacking amino acids 333 to 575 was detected in the nuclei of the transfected cells, whereas the other mutant lacking amino acids 900 to 950 was detected mainly in the cytoplasm. These results suggest that the region of amino acids 900 to 950 is responsible for nuclear localization of IE180.
