Abstract
Linelike features in TeV γ rays constitute a "smoking gun" for TeV-scale particle dark matter and new physics. Probing the Galactic Center region with ground-based Cherenkov telescopes enables the search for TeV spectral features in immediate association with a dense dark matter reservoir at a sensitivity out of reach for satellite γ-ray detectors, and direct detection and collider experiments. We report on 223 hours of observations of the Galactic Center region with the MAGIC stereoscopic telescope system reaching γ-ray energies up to 100 TeV. We improved the sensitivity to spectral lines at high energies using large-zenith-angle observations and a novel background modeling method within a maximum-likelihood analysis in the energy domain. No linelike spectral feature is found in our analysis. Therefore, we constrain the cross section for dark matter annihilation into two photons to ⟨σv⟩≲5×10^{-28} cm^{3} s^{-1} at 1 TeV and ⟨σv⟩≲1×10^{-25} cm^{3} s^{-1} at 100 TeV, achieving the best limits to date for a dark matter mass above 20 TeV and a cuspy dark matter profile at the Galactic Center. Finally, we use the derived limits for both cuspy and cored dark matter profiles to constrain supersymmetric wino models.

Abstract
On January 14, 2019, the Major Atmospheric Gamma Imaging Cherenkov telescopes detected GRB 190114C above 0.2 TeV, recording the most energetic photons ever observed from a gamma-ray burst. We use this unique observation to probe an energy dependence of the speed of light in vacuo for photons as predicted by several quantum gravity models. Based on a set of assumptions on the possible intrinsic spectral and temporal evolution, we obtain competitive lower limits on the quadratic leading order of speed of light modification.

Abstract
Sperm characteristics of Romerolagus diazi, an endemic endangered rabbit from Mexico's Higlands, are poorly known. Knowledge of gamete characteristics are urged for any conservation-oriented strategy and morphometry-based taxonomical database. Sperm lagomorph comparisons have been made at light microscopy resolution. Our goal was to analyze the ultrastructure of the R. diazi male gamete. Two wild animals were kept in captivity and the epididymus were obtained. Fixed gametes show a characteristic spatula-like morphology with a dilated forefront. The nucleus has an arrow head morphology lightly thicker at the base. Tail ultrastructure is similar to that of laboratory rabbits with an end piece thicker than that of human sperm. Morphometry data could be used for construction of a male gamete data base for further studies.

Abstract
The expression of masculine sexual behavior (MSB) in male hamsters is optimally stimulated by aromatizable androgens like androstenedione (AD) and testosterone (T), while the non-aromatizable androgen, 5alpha-dihydrotestosterone (DHT), exerting potent androgenic peripheral effects, only in high doses maintains MSB after castration. No data exist on the ability of these androgens to restore long intromissions after castration. In this study, AD, T, and DHT were administered to four-week gonadectomized, sexually experienced male hamsters, for three weeks, in doses of 25 microg/day or up to 1000 microg/day to compare their potency in restoring MSB, penile size, and penile spines growth. Plasma levels of these steroids and the metabolites estrone and estradiol, were determined at the end of the treatment period. Gonadectomy completely suppressed MSB and induced a regression of penile spines. AD was more potent than T in restoring MSB, ejaculatory behavior being displayed by most castrated subjects with a lower dose of AD (50 microg/day) than of T (300 microg/day), and long intromissions being shown by all AD-treated castrated hamsters but only by 20% of T-treated ones, when doses of 1000 microg/day were given. DHT did not stimulate any copulatory response. The three androgens, even at the lowest dose, partially stimulated penis and penile epithelium growth, DHT showing the highest potency. Treatment of castrated hamsters with AD (50 microg/day), restored steroid levels to similar values as those of intact animals. These results show that AD and T restored MSB even with a partial stimulation of penile spines growth, AD being more potent than T. In contrast, DHT did not restore MSB in the hamster in spite of its peripheral androgenic potency.

Abstract
Microquasars are binary star systems with relativistic radio-emitting jets. They are potential sources of cosmic rays and can be used to elucidate the physics of relativistic jets. We report the detection of variable gamma-ray emission above 100 gigaelectron volts from the microquasar LS I 61 + 303. Six orbital cycles were recorded. Several detections occur at a similar orbital phase, which suggests that the emission is periodic. The strongest gamma-ray emission is not observed when the two stars are closest to one another, implying a strong orbital modulation of the emission or absorption processes.

Abstract
Whereas virotherapy has emerged as a novel and promising approach for neoplastic diseases, appropriate model systems have hampered preclinical evaluation of candidate conditionally replicative adenovirus agents (CRAds) with respect to liver toxicity. This is due to the inability of human viral agents to cross species. We have recently shown the human liver tissue slice model to be a facile means to validate adenoviral replication. On this basis, we sought to determine whether our ex vivo liver tissue slice model could be used to assess CRAd-mediated liver toxicity. We analyzed and compared the toxicity of a conditionally replicative adenovirus (AdDelta24) to that of a replication incompetent adenovirus (Adnull [E1-]) in mouse and human liver tissue slices. To accomplish this, we examined the hepatic apoptosis expression profile by DNA microarray analyses, and compared these results to extracellular release of aminotransferase enzymes, along with direct evidence of apoptosis by caspase-3 immunhistochemical staining and TUNEL assays. Human and mouse liver tissue slices demonstrated a marked increase in extracellular release of aminotransferase enzymes on infection with AdDelta24 compared to Adnull. AdDelta24-mediated liver toxicity was further demonstrated by apoptosis induction, as detected by caspase-3 immunohistochemical staining, TUNEL assay and microarray analysis. In conclusion, concordance of CRAd-mediated apoptosis in both the human and the mouse liver tissue slice models was demonstrated, despite the limited replication ability of CRAds in mouse liver slices. The results of this study, defining the CRAd-mediated apoptosis gene expression profiles in human and mouse liver, may lay a foundation for preclinical liver toxicity analysis of CRAd agents.

Abstract
Ischemia-reperfusion injury (I/R-I), which is unavoidable in liver transplantation, impairs liver regeneration and predisposes to liver failure. The three major mitogen-activated protein-kinases (MAPKs): ERK, p38, and JNK, are critical in the transmission of signals triggered by proinflammatory cytokines, by stress, and by growth factors. JNK and p38alpha activation have been associated with apoptosis; p38beta with cell survival; and ERK with proliferation. Previous studies have demonstrated gender dimorphism in hepatocellular dysfunction after experimental trauma and hemorrhage. Female mice are protected to a much greater extent from I/R-I than male mice. We assessed the effects of 17beta-estradiol (17beta-E) on liver function, host survival, and cellular activation of MAPK in a murine model of I/R-I in reduced-size livers. C57BL/6 mice were subjected to 45 minutes of warm ischemia (70% of the liver mass). After reperfusion, the nonischemic lobes were excised. Vehicle, 17beta-E or the estrogen receptor antagonist ICI-182780, was delivered 1 hour before the injury. We evaluated AST and apoptosis as well as activation of JNK, p38, and ERK. Female mice showed a lower level of hepatocellular injury (AST = 445 +/- 82 IU/L) after I/R-I compared with male mice (AST = 1400 +/- 210). 17beta-E decreased the liver injury in male mice (AST = 522 +/- 77), an effect that was partially reversed by ICI-182,780 (910 +/- 92). A higher rate of apoptosis was observed in male animals given saline (enrichment factor = 7.22 +/- 0.8) versus those treated with 17beta-E (5.85 +/- 0.3, P < .05). A significant increase in liver regeneration, as assessed by the percentage of liver weight/body weight was demonstrated in females (184% +/- 24%) and male mice given 17beta-E (168% +/- 22%) compared with male mice given vehicle (9% +/- 4%). 17beta-E significantly down-regulated JNK and p38alpha activities, whereas I/R-I promoted p38beta and ERK activation. These results suggest that the cytoprotective effects of 17beta-E on I/R-I to reduced-size livers are associated with selective modulation of MAPK kinases.

Abstract
BACKGROUND Exposing adult porcine pancreatic islets (PI) to xenoreactive natural antibodies (XNA) induces brisk inflammatory injury that involves activation of the complement system. Gene transfer of Bcl-2 has been shown to protect PI from apoptosis and necrosis in several models. In this study, we investigated the effect of Bcl-2 gene transfer on protection of PI from primate XNA and complement-mediated injury. METHODS The PI were isolated from adult female sows. Only islet preparations that exhibited >90% viability and purity were used. Fresh rhesus monkey serum served as the XNA source. Gene transfer of Bcl-2 was achieved with an adenoviral vector (AdBcl-2) at 500 particle forming units (pfu)/cell. The Bcl-2 expression was confirmed by Western blot technique. Untransfected and transfected PI were incubated in 50% fresh complete serum (CS) or heat-inactivated (HI) rhesus serum for 24 hours. The PI viability was analyzed with acridine orange and ethidium bromide staining. Antibody and complement-mediated cytotoxicity were tested by intracellular lactate dehydrogenase (LDH) release. The PI function was assessed in vitro by static incubation studies and in vivo after intraportal transplantation in diabetic severe combined immunodeficiency (SCID) mice. RESULTS The AdBcl-2 gene transfer resulted in Bcl-2 gene expression in >90% of PI cells. Following exposure to XNA, <15% of the untransfected cells were viable. Similar results were obtained in PI transfected with a similar recombinant adenovirus encoding the reporter gene E coli beta-galactosidase (AdLacZ), an irrelevant gene. A significant increase in LDH release was observed in control PI after exposure to CS compared with PI that overexpressed Bcl-2 (82.89% +/- 7.78% vs 34.31% +/- 5.4%, P <.005). Higher insulin release was observed in vitro in PI transfected with Bcl-2 compared with untransfected PI or islets transfected with AdLacZ (stimulation index of 0.9 +/- 0.31, 0.9 +/- 0.3 vs 2.67 +/- 0.4, respectively). Only PI treated with AdBcl-2 were able to achieve euglycemia after exposure to XNA and complement after transplantation. CONCLUSIONS Transfer of the antiapoptotic and antinecrotic Bcl-2 gene into PI can reduce primate XNA and complement-mediated lysis. Cytoprotection of PI with Bcl-2 has potential to improve survival of PI xenotransplants.

Abstract
BACKGROUND This study examines the mechanisms of early isolated islet apoptosis (II-APO) and loss of functional islet mass. METHODS Rhesus islets were isolated for transplantation, and an aliquot was used for in vitro molecular studies of II-APO. These studies used Western blotting to examine caspase activation and perinuclear envelope protein cleavage that are associated with II-APO and used immunofluorescence analysis of Annexin V and mitochondrial permeability index to examine spontaneous and tripartite anoikis-like (TRAIL) mechanism--induced II-APO. RESULTS Caspase 6 was prominently activated in association with spontaneous II-APO, which occurred after overnight culture. In contrast, caspase 7, 8, and 9 were not activated. Cleavage of focal adhesion kinase and Lamin, substrates of caspase 6, was also evident in spontaneous II-APO. II-APO was exaggerated by the addition of the TRAIL mechanism. The TRAIL mechanism--induced II-APO was blocked by the caspase 6 inhibitor, VEID, and by the soluble fusion proteins, DR4 or DR5, which act as decoy receptors. In vivo studies in diabetic severe combined immunodeficiency disease mice showed that rhesus islets were cytoprotected by either ex vivo gene transfer of Bcl-2 or treatment of the isolated islet with VEID. CONCLUSIONS These studies suggest 3 major mechanisms involved in II-APO: caspase 6 activation, a TRAIL-induced apoptosis pathway, and the mitochondrial-associated apoptosis pathway. Inhibition of these II-APO pathways may improve isolated islet survival and reduce functional islet mass loss, which compromises the stable reversal of diabetes.

Abstract
The recent focus on islet transplantation as primary therapy for type 1 diabetes has heightened interest in the reversal of type 1 diabetes in preclinical models using minimal immunosuppression. Here, we demonstrated in a preclinical rhesus model a consistent reversal of all measured glycemic patterns of streptozotocin-induced type 1 diabetes. The model used single-donor islet transplantation with induction of operational tolerance. The term "operational tolerance" is used to indicate durable survival of single-donor major histocompatibility complex (MHC)-mismatched islet allografts without maintenance immunosuppressive therapy and without rejection or loss of functional islet mass or insulin secretory reserve. In this operational tolerance model, all immunosuppression was discontinued after day 14 posttransplant, and recipients recovered with excellent health. The operational tolerance induction protocol combined peritransplant anti-CD3 immunotoxin to deplete T-cells and 15-deoxyspergualin to arrest proinflammatory cytokine production and maturation of dendritic cells. T-cell deficiency was specific but temporary, in that T-cell-dependent responses in long-term survivors recovered to normal, and there was no evidence of increased susceptibility to infection. Anti-donor mixed lymphocyte reaction responses were positive in the long-term survivors, but all showed clear evidence of systemic T-helper 2 deviation, suggesting that an immunoregulatory rather than a deletional process underlies this operational tolerance model. This study provides the first evidence that operational tolerance can protect MHC nonhuman primate islets from rejection as well as loss of functional islet mass. Such an approach has potential to optimize individual recipient recovery from diabetes as well as permitting more widespread islet transplantation with the limited supply of donor islets.

Abstract
T-cell reduction utilizing specific antibody has been widely used in human transplantation, and is a cornerstone of several tolerance induction strategies in nonhuman primates. We have established a population of long-term tolerant rhesus macaques induced with an anti-CD3epsilon immunotoxin (IT). This treatment effects transient, specific and profound ablation of T cells in blood and lymphoid tissues. In most instances the IT was used in combination with the NF-kappaB inhibitor, 15-Deoxyspergualin. This 2-week long protocol produces a "window of opportunity" for tolerization in which the animal exhibits an enduring quiescent state of unresponsiveness to the allograft, all accomplished without maintenance immunosuppressive drugs. During this induction period, the treated immune system bears some resemblance to that of the neonate, in that T cell numbers are abnormally low and antigen presentation by dendritic cells is precluded by an arrest in their NF-kappaB dependant maturation. In addition, IL-4 production is prominent during and after the tolerance induction interval. For this study we focused on measuring the monkey's ability to repopulate T cells with particular emphasis on the memory T-cell phenotype. Three "memory" phenotypes were utilized; CD3(+)CD45RO(+), CD3(+)CRTH2(+), and CD3(+)CD4(+)CD8(+). All three phenotypes exhibited different patterns of recovery, all of which included transient bursts in their numbers during repopulation. We also estimated thymic activity after T-cell ablation with the use of a newly-described RTE or recent thymic émigré phenotype (a naïve CD8(+)CD103(+) T cell). This marker revealed production of RTE cells including supranormal levels at approximately 6 months post-transplant, implicating thymic function in the repopulation of T-cells. Finally, we measured antibody responses to a panel of antigens (vaccines, environmental antigen, and foreign proteins) that indicated there was no apparent loss of immunologic function during or after the tolerance induction period. Results of studies of T-cell receptor repertoire expression suggest preservation of the pretreatment repertoire, which is consistent with rapid recovery of immune competence to the test antigens. Taken together, these results suggest that while aggressive, this tolerance induction protocol does not appear to incur a prolonged immunologically-compromised state, if at all.

Abstract
Sexual behavior was evaluated in sexually experienced male rabbits after the administration of different serotonergic drugs. The serotonin1A receptor agonist 8-OH-DPAT, 1 mg/kg, inhibited male rabbit sexual behavior when animals were tested 15 min after subcutaneous (SC) administration of this compound. Lower doses, 0.25 and 0.5mg/kg, were ineffective at a test 30 min after drug injection. Furthermore, 8-OH-DPAT, 0.25mg/kg, failed to revert the inhibitory effects upon sexual behavior produced by lidocaine application to the rabbit penis. Stimulation of 5-HT1B/2C receptors by TFMPP, at doses between 0.625 and 2.5 mg/kg, produced a drastic inhibition of sexual behavior when the drug was administered SC 30 min before behavioral observation. Doses below 5mg/kg were ineffective when given intraperitoneally 15 min before test. When the 5-HT1D/2C receptors were stimulated by the agonist mCPP a reduced number of mounts and ejaculations was observed after the SC administration of 1.25 and 2.5 mg/kg. Similarly, the mixed 5-HT agonist/antagonist lisuride reduced the percentage of rabbits displaying mounting behavior at doses of 0.25 and 0.5 mg/kg SC. All compounds tested produced a clear inhibition of male rabbit sexual behavior independently of the receptor subtype activated. These results are at variance with previous observations in rats where 8-OH-DPAT and lisuride produced a drastic facilitation of masculine coital behavior. Moreover, while the inhibition of male sexual behavior in rats produced by TFMPP and mCPP is associated with a disruption of the execution of this behavior, in rabbits these compounds reduced sexual motivation. These results indicate that the effects of serotonergic drugs on sexual behavior are species specific.

Abstract
During evaluation for liver transplantation, a 63-year-old man with cirrhosis secondary to hepatitis C was diagnosed with severe aortic stenosis (aortic valve area, 0.87 cm(2)) and coronary artery disease. A combined procedure involving aortic valve replacement (pericardial xenograft), coronary artery bypass surgery, and orthotopic liver transplantation was performed. Convalescence was uneventful, and at 2 years after the procedure, the patient has normal cardiac function, good prosthetic valve function, and biochemically normal liver function.

Abstract
Nonhuman primates provide an optimal model for the evaluation of tolerance in the preclinical setting. Transplantation and management of nonhuman primates are technically demanding, and the purpose of this article is to review our extensive experience in renal transplantation in non-human primates, with particular emphasis on modifications of surgical techniques on urologic complications. We retrospectively reviewed our results with 329 renal transplants in rhesus monkeys over an 18-year period. The surgical technique and, in particular, the ureteroneocystostomy have evolved over this period of time. This review extensively details our current technique, the surgical and urologic complications, and their management. There were 329 renal transplants performed. There were 85 early deaths, or animals euthanized, within 30 days of the transplant operation. In the first 15 years, there were 27 (10.68%) surgical complications that required euthanasia, and in the last 3 years the complication rate has been reduced to 5 (7.3%, p < .05). The routine use of microsurgical techniques has reduced the incidence of arterial thrombosis (6.2% vs. 2.9%, p < .05). The incidence of ureteral strictures (15 vs. 0, p < .005) has been reduced by a modification of the ureteroneocystostomy technique detailed in the text. Renal transplantation in small rhesus monkeys is technically demanding. The routine use of microsurgical techniques and a modified ureteroneocystostomy has reduced the incidence of surgical complications.

Abstract
Tolerance induction can prevent acute kidney allograft rejection without chronic immunosuppression. It is uncertain whether specific tolerance can prevent chronic allograft nephropathy (CAN), which involves both nonimmune and immune injury. This report provides evidence that immunologically tolerant macaques, induced with immunotoxin and deoxyspergualin, developed neither acute rejection nor CAN. Long survivors, bearing MHC-mismatched grafts without chronic immunosuppression for 0.8 to 3.4 years, exhibited general immune competence with donor-specific T and B cell tolerance and no functional or histological evidence of CAN. Stringent criteria for tolerance were satisfied by specific prolongation of donor skin grafts with rapid rejection of third-party skin, followed by indefinite acceptance of a second donor kidney graft and establishment of microchimerism. Primate tolerance with documented absence of CAN may give impetus to the clinical application of tolerance.

Abstract
BACKGROUND The issue of containing cost has had a significant impact on organ transplantation. After our institution's 500th liver transplant, we critically examined the impact of the changing health care environment on liver transplantation. METHODS We retrospectively analyzed 500 consecutive liver transplants done in the period of 1989 to 1998. RESULTS Comparing the first 100 liver transplants to the last 100, patient demographics did not change significantly; however, mean waiting times increased significantly, from 30.4 days to 146.7 days, and median hospital stay decreased from 20.2 days to 10.9 days. One-year patient and graft survivals were not significantly different, 93.6% versus 96.5% and 88.0% versus 95.7%, respectively. CONCLUSIONS Despite transplants in patients at higher risk and discharging patients sooner after transplantation, surgical results and patient survivals remained excellent. This was accomplished through improvements and modification of immunosuppression, outpatient treatment of uncomplicated acute rejection, and emphasis on close outpatient follow-up.

Abstract
BACKGROUND Pancreatic islet transplantation (PIT) is an attractive alternative for patients with type I diabetes mellitus. PIT is not yet an effective clinical reality due in part to the high incidence of rejection and early loss of functional islet mass. In addition, current immunosuppressive drugs have toxic effects on islets and increase the risk of morbidity and mortality. In the present study, the effects of PIT on glycemic parameters were assessed in spontaneously diabetic primates. METHODS Five insulinopenic nonhuman primates (three Macacca fascicularis, one Ceropithecus aethiops, and one Macacca mulatta) were studied. All required twice-daily treatment with 4-10 U of insulin. For immunosuppression, the animals received anti-CD3-immunotoxin (100 microg/kg(initially infused 2 hr before transplantation and again on day +1), cyclosporine (CsA) (20 mg/kg(i.v./2 hr before transplantation), cyclosporine microemulsion (Neoral) 60 mg/kg/b.i.d. on days +1 to +3 with dose adjusted by blood levels, and methylprednisolone (15 mg/kg day 0 to +3). Three recipients were given islets from a single donor (M mulatta). The islets were prepared by a semiautomated technique using Liberase. A mean of 13,136 islet equivalents/kg was infused into the portal vein. Two animals (M fascicularis and M mulatta) were used as a diabetic, nontransplanted control. Several metabolic parameters were evaluated. RESULTS All monkeys that underwent transplantation experienced reversal of diabetes mellitus with normalization of all diabetic glycemic parameters. In the nontransplanted primates given the same immunosuppression but no PIT, diabetic metabolic parameters were unchanged after 9 months of follow-up. In contrast, all three PIT recipients established fasting and nonfasting euglycemia within 1-2 weeks, and none required exogenous insulin after day 10. Normal intravenous glucose tolerance tests were observed at day 15, and no significant differences in the glucose disappearance rate (Kg) were observed at days 15, 45, 190, and 365 days after transplantation. The acute insulin response to glucose indicated no significant reduction of functional islet mass. CONCLUSIONS PIT in severely insulinopenic type I diabetes mellitus primates resulted in restoration of normal glycemic parameters and durable islet mass. Operational tolerance was achieved with only 4 days of drug administration, sparing the animals from chronic exposure to potentially diabetogenic immunosuppressive drugs. These results offer an exciting new potential for type I diabetes mellitus treatment.

Abstract
OBJECTIVE The safety and efficacy of endoscopic retrograde cholangiopancreatography (ERCP) in the evaluation and management of biliary tract complications after orthotopic liver transplantation (OLT) have been previously demonstrated. However, the role of ERCP in evaluating asymptomatic OLT patients with abnormal liver enzymes with a previously normal biliary tree remains poorly defined. We sought to assess the utility of ERCP in this subset of patients. METHODS A retrospective analysis of-asymptomatic OLT patients with abnormal liver enzymes evaluated by ERCP was undertaken. In addition to ERCP, all these patients had a diagnostic abdominal Doppler ultrasound, and a percutaneous liver biopsy. All patients had choledochocholedochostomy at the time of transplant and normal T-tube cholangiograms 3 months postoperatively. A radiologist, blinded to clinical findings, interpreted the ultrasound as normal, biliary dilation, or vascular abnormalities. The same radiologist interpreted ERCP findings. A pathologist, blinded to clinical findings, graded liver biopsies as normal, diagnostic, or abnormal but nondiagnostic. RESULTS Twenty-two patients underwent 23 ERCPs. Twenty-two of the 23 ERCPs were normal (96%), and one abnormal ERCP finding did not explain the liver enzyme abnormality. Liver biopsy was diagnostic in 13 of 22 (57%) and in each case the ERCP was normal. The remaining 10 liver biopsies were abnormal but nondiagnostic. Ultrasound was abnormal in five of 22 cases, but in the three cases suggesting biliary dilation, the ERCP was interpreted as normal. CONCLUSION Routine use of ERCP in evaluation of asymptomatic OLT patients with liver function test abnormalities and normal cholangiograms at 3 months was not diagnostically useful. In this subset of patients, liver biopsy was usually abnormal and frequently diagnostic and should be the initial invasive diagnostic procedure.

Abstract
To develop a cellular vehicle able to reach systemically disseminated areas of angiogenesis, we sought to exploit the natural tropism of circulating endothelial progenitor cells (EPCs). Primate CD34+ EPCs were genetically modified with high efficiency and minimal toxicity using a non-replicative herpes virus vector. These EPCs localized in a skin autograft model of angiogenesis in rhesus monkeys, and sustained the expression of a reporter gene for several weeks while circulating in the blood. In animals infused with autologous CD34+ EPCs transduced with a thymidine kinase-encoding herpes virus, skin autografts and subcutaneous Matrigel pellets impregnated with vascular growth factors underwent necrosis or accelerated regression after administration of ganciclovir. Importantly, the whole intervention was perfectly well tolerated. The accessibility, easy manipulation, lack of immunogenicity of the autologous CD34+ cell vehicles, and tropism for areas of angiogenesis render autologous CD34+ circulating endothelial progenitors as ideal candidates for exploration of their use as cellular vehicles when systemic gene delivery to those areas is required.

Abstract
BACKGROUND Day of transplant T cell depletion with anti-CD3 immunotoxin or F(Ab)2 immunotoxin induces stable tolerance to renal allografts in rhesus monkeys given 15-deoxyspergualin (DSG), a NF-kappaB inhibitor that suppresses proinflammatory cytokine (PC) production. Because PC and NF-kappaB are involved in dendritic cell (DC) maturation, we asked if impaired DC maturation and Th2-type cytokine deviation might be related to the synergistic effect of DSG in this novel model. METHODS Immunosuppression was initiated 4 hr before transplanting a major histocompatibility complex mismatched renal allograft. Some groups received a supplemental 5-day course of cyclosporine A or DSG or a 15-day course of DSG. Peripheral lymph nodes were sequentially examined for presence of mature DC. In vitro effects of DSG on PC-induced maturation of DC were also examined. RESULTS Allografts survived without rejection in 87% of recipients given immunotoxin or F(Ab)2 immunotoxin with DSG x 15 days, in 50% with DSG x 5 days, and 0% with cyclosporine A. The longest DSG survivors are >1000 days with normal graft function and tolerance validated, including acceptance of challenge second donor kidneys without treatment. DSG-treated recipients were unique in developing polarized Th2-type plasma cytokines. In DSG recipients, mature DC were significantly reduced in day +5 lymph node biopsies, with complete repopulation by 30 days. In vitro studies verified an inhibitory effect of DSG on DC maturation. CONCLUSIONS The study suggests DSG arrests DC maturation. The unusual synergy of immunotoxin and DSG apparently involves coincidental reduction in lymph node T cell mass and mature DC, a transient circumstance favoring development of stable tolerance.

Abstract
BACKGROUND Isolated cell transplantation (ICT) of pancreatic islets (PI), nerve tissue, hepatocytes, and other cells is an exciting new concept of transplantation. PI transplantation can be successful in reversing diabetes but, unlike whole pancreas, grafts have a unique and unexplained high failure rate, with over 60% loss by 3 to 6 months. We established that PI of rhesus monkeys have a high rate of death within 48 hours of isolation as a result of apoptosis, as measured with the Annexin V assay (Pharmingen, San Diego, Calif). In contrast, PI incompletely separated from the extracellular matrix (ECM) remained viable for prolonged periods in culture and performed superiorly in perifusion assays (insulin secretion of 4.6 +/- 0.8 times basal secretion). METHODS We studied the ability of the anti-AP Bcl-2 molecule, known to block anoikis (a mechanism of AP due to cell-ECM separation), to prevent apoptosis of isolated PI. RESULTS PI transduced with an adenovirus-Bcl-2 gene complex showed a high viability and a low AP rate in culture versus control rhesus PI. CONCLUSION In summary, PI protected from AP by a surrounding ECM mantle or by Adenovirol Vector (AdV) transduction of the Bcl-2 gene showed superior viability without AP in vitro and in vivo evidence of a preserved insulin secretion response to glucose.

Abstract
OBJECTIVE To examine the possibility of reducing ischemia-reperfusion injury (I/R injury) to the mouse liver by in vivo adenovirus-mediated gene transfer of the antiapoptotic human Bcl-2 gene. SUMMARY BACKGROUND DATA Ischemia-reperfusion injury has been demonstrated in a number of clinically relevant diseases such as myocardial infarction, cerebrovascular disease, sepsis, peripheral vascular disease, and organ transplantation. In this regard, apoptosis plays a central role. METHODS Normal C57BL/6 mice were used. An adenovirus (deltaE1) vector containing the human Bcl-2 gene was developed in the authors' laboratory. An adenovirus vector encoding an irrelevant gene (beta-galactosidase, AdCMVLacZ) was used as a control. Taking advantage of the hepatotropic properties of adenovirus vectors, gene transfer was performed with 1 x 10(9) plaque-forming units by intravenous tail injection, 48 hours before the ischemic injury. Ischemic-reperfusion injury was induced by temporal and segmental occlusion of hepatic blood flow. Aspartate aminotransferase, alanine aminotransferase, and lactate dehydrogenase activity was measured using standard assays. Liver biopsies were obtained before and 6 hours after I/R injury for morphologic assessment, and apoptosis was determined in situ with a histochemical assay. RESULTS The expression of AdCMVhBcl-2 vector was confirmed by reverse transcription-polymerase chain reaction and functionally validated in apoptotic studies in endothelial cells. Expression of the Bcl-2 gene protects against I/R injury, as shown by a significant decrease in transaminases (p < 0.05) and necrosis and apoptosis (p < 0.001), and permanent survival (p < 0.0001), compared with sham-operated animals and animals treated with AdCMVLacZ. CONCLUSIONS Genetic modification of the liver to induce cytoprotection has potential applications to prevent I/R injury to the liver in surgical interventions, including liver transplantation.

Abstract
An adenovirus vector encoding the human Bcl-2 gene (hBcl-2) was derived. In vivo expression of hBcl-2 in murine livers enhanced and prolonged adenovirus-mediated gene expression. Furthermore, in the hBcl-2-treated group a significant reduction in the apoptosis induced by the adenovirus vector was observed. Thus, the cytoprotection of the vector-infected cells with antiapoptotic genes appears promising for successful in vivo gene therapy.

PI transplantation can be successful in reversing diabetes but, unlike whole pancreas, grafts have a unique and unexplained high failure rate, with over 60% loss by 3 to 6 months. We established that PI of rhesus monkeys have a high rate of death within 48 hours of isolation as a result of apoptosis, as measured with the Annexin V assay (Pharmingen, San Diego, Calif). In contrast, PI incompletely separated from the extracellular matrix (ECM) remained viable for prolonged periods in culture and performed superiorly in perifusion assays (insulin secretion of 4.6 +/- 0.8 times basal secretion). METHODS We studied the ability of the anti-AP Bcl-2 molecule, known to block anoikis (a mechanism of AP due to cell-ECM separation), to prevent apoptosis of isolated PI. RESULTS PI transduced with an adenovirus-Bcl-2 gene complex showed a high viability and a low AP rate in culture versus control rhesus PI. CONCLUSION In summary, PI protected from AP by a surrounding ECM mantle or by Adenovirol Vector (AdV) transduction of the Bcl-2 gene showed superior viability without AP in vitro and in vivo evidence of a preserved insulin secretion response to glucose.

Abstract
INTRODUCTION Anti-CD3-immunotoxin (alpha-CD3-IT) promotes allograft tolerance in nonhuman primates owing to efficient depletion of sessile and circulating T cells. Common side effects of vascular leak syndrome, hepatotoxicity, and nephrotoxicity have limited tolerability of other immunotoxins. We report on preclinical studies of alpha-CD3-IT-related side effects. METHODS Normal rhesus monkeys received a kidney transplant and alpha-CD3-IT alone (on day -to +2) or in combination with brief peritransplant adjunctive immunosuppressive therapy. Some received donor CD34+ cells. Blood chemistries, complete blood count, weight, liver, and kidney biopsies were examined for immunotoxin-related changes. Five spontaneously diabetic primates also received alpha-CD3-IT, three of whom had a pancreas islet transplant. RESULTS The main side effect of alpha-CD3-IT, vascular leak syndrome, was entirely prevented by adjunctive immunosuppressive therapy. Renal and liver function tests and biopsies revealed a lack of nephrotoxicity and hepatotoxicity. All had transient weight loss (14+/-5%). Without infusion of donor CD34+ cells, 97% had full weight recovery. Of those given donor CD34+ cells, 50% were euthanized for wasting. CONCLUSIONS Side effects of alpha-CD3-IT are manageable and should not prevent therapeutic application.

Abstract
BACKGROUND Isolated pancreatic islet transplantation (IPITx) is an attractive alternative for treatment of insulin-dependent diabetes mellitus (IDDM). However, IPITx has been difficult to implement clinically because islets frequently fail to function, have a high incidence of rejection, and are susceptible to autoimmune recurrence and damage by chronic immunosuppressive therapy. Tolerance induction may be a rational approach to resolve several of these limitations. Because anti-CD3 immunotoxin (IT) has been successful in promoting stable primate kidney transplant tolerance in our experience, we considered that tolerance induction with IT might be duplicated in IPITx. MATERIALS AND METHODS Three monkeys with spontaneous IDDM (two Macaca fascicularis and one Ceropithecus aethiops) were treated with xenogeneic pancreatic islets (Macaca mulatta). Intrahepatic islet transplantation was performed at a mean of 13136+/-3860 islet equivalents/kg. Islet xenograft acceptance was accomplished by tolerance induction with two injections of IT given on day 0 at 2 hr before transplantation and on day +1, respectively. IT treatment was supplemented with cyclosporine and steroids administered on days 0 through 4. No additional immunosuppression was given thereafter. Two additional control macaques with spontaneous IDDM received the immunosuppressive protocol without islet infusion. RESULTS All recipients were restored to stable euglycemia, off exogenous insulin, within 1-2 weeks after transplantation. Glucose tolerance, C-peptide, and glycosylated hemoglobin tests confirmed the restoration of normal glucose homeostasis after islet transplantation. All three islet recipients have remained euglycemic at 410, 255, and 100 days of follow-up despite recovery of peripheral T cells to normal levels. In contrast, none of the controls presented changes in the diabetic status 4 and 8 months after treatment. CONCLUSIONS These results represent the first demonstration in nonhuman primates of stable, long-term acceptance of nonencapsulated xenogeneic islets off all immunosuppression, suggesting operational tolerance. The findings have potential implications for islet transplantation as well as improved and more cost-effective therapy for IDDM.

Abstract
BACKGROUND Liver function after transplantation is determined by the quality of the donor organ and the influences of preservation, flush, and reperfusion injury. In this regard, cell death (apoptosis) plays an important role in organ preservation and rejection. Therefore, we examined the possibility of genetic modification of the liver graft with a recombinant adenovirus vector encoding the Bcl-2 gene to reduce apoptosis during the preservation time. METHODS Liver grafts from C57B1/6 mice were procured and preserved using standard techniques. A replication defective adenovirus vector (deltaE1) containing the human Bcl-2 gene (AdCMVhBcl-2) was developed in our laboratory. An adenovirus vector encoding an irrelevant gene (Escherichia coli beta-galactosidase) was used as a control. Each mouse received 1 x 10(9) plaque forming units administered i.v. 48 hr before the liver procurement. Analyses of liver enzyme activities were determined in the preservation solution. Apoptosis in liver biopsies was determined by DNA fragmentation with an in situ histochemical assay. RESULTS Immunohistochemical analysis and RT-PCR confirmed the expression of hBcl-2 in the grafts. Grafts from livers expressing hBcl-2 showed significant reduction of the aspartame amino transferase (AST) and lactate dehydrogenase (LDH) release compared with grafts from the control groups. After rewarming, significant cytoprotection was also observed in grafts from animals treated with AdCMVhBcl-2. Histological analysis correlated with the hepatocellular injury determined with transaminases and LDH in the preservation solution. Significant reduction in the number of apoptotic cells was observed in grafts expressing hBcl-2. CONCLUSIONS We have demonstrated a novel approach to reducing the preservation injury to liver grafts with the human Bcl-2 gene. This approach may allow a longer preservation time, potentially reduce the incidence of primary nonfunction, decrease the immunogenicity of the cold injured organ, and increase the safer use of "marginal" liver grafts.

Abstract
BACKGROUND Allogeneic bone marrow cell (allo-BMC) infusion induces tolerance to incompatible renal allografts in rhesus macaques after depletion of peripheral T lymphocytes with cytolytic anti-T cell antibodies. The tolerogenic effect of allo-BMC, ascribed to a veto mechanism, associates with specific functional deletion of antidonor cytotoxic T lymphocyte precursor (CTLp), and is dependent on a CD8+ donor BMC subset. In previous studies, the CD8 molecule was implicated by loss of suppression after blocking interaction between CD8 on allo-BMC and major histocompatibility complex class Ialpha3 domain on CTLp. CD8 cross-linking on BMC induced secretion of active transforming growth factor-beta1 (TGF-beta1), suggesting a regulatory mechanism(s) operating via a CD8-mediated signaling pathway. METHODS CD8 on rhesus cells was cross-linked using IgG-conjugated beads, and TGF-beta1 mRNA and protein were quantified. CD8+ cells were tested for veto activity by mixed lymphocyte reaction (MLR)-induced cell-mediated lymphocytotoxicity (CML) assay. Activated rhesus T cells exposed to TGF-beta1 were examined for apoptosis by TdT-mediated end-labeling and annexin staining. RESULTS CD8 cross-linking induces accumulation of TGF-beta1 mRNA and protein. Both CD3- CD8+CD16+ and CD3+ CD8+CD16- subsets of allo-BMC up-regulate TGF-beta1 mRNA after CD8 cross-linking, and exhibit veto activity. The CD3-CD8+CD16+ subset expresses more TGF-beta1 mRNA and increased veto activity at low BMC/CTLp ratios. Exposure of activated T cells to TGF-beta1 induces apoptosis. CONCLUSIONS CD8+ allo-BMC are enriched for veto activity and activation via CD8 induces TGF-beta1 mRNA and protein accumulation. These results agree with the hypothesis that paracrine TGF-beta1 may be involved in peripheral deletion of alloreactive CTLp by CD8+ allo-BMC. We suggest that TGF-beta1 overexpression by donor lymphohematopoietic cells may enhance tolerance induction.

Abstract
The influence of ethnic origin on organ donation and renal allograft survival after renal transplantation has been controversial. Several large studies have reported inferior renal allograft survival in black recipients, whereas others have reported equal survival. However, the issue of race as it relates to organ donation, patient referral, and patient selection in orthotopic liver transplantation has not been investigated. We retrospectively reviewed our results of organ donation, patient referral and selection, and orthotopic liver transplantation since 1989. Because of a concerted educational effort by this organ procurement organization, the percentage of black donors has increased from 6.1% in 1988 to 21.9% in 1996. Since the inception of the Liver Transplant Program in 1989, 844 patients have been referred to our transplant center for organ transplant evaluation. Disproportionately fewer black patients (119; 14.1%) were referred for liver transplantation than white patients (725; 85.9%) based on the prevalence of end-stage liver disease in these populations. The acceptance rate for listing for transplantation was similar between the two groups. The percentage of patient referrals who actually underwent transplantation was similar across racial lines (43% black v 42% white patients). However, it appeared that black patients were referred for liver transplantation at a later stage and were more critically ill at the time of referral. Nevertheless, the patient and graft survival were similar between black and white patients. The 1- and 3-year survival rates in white recipients was 88% and 81%, respectively, versus 96% and 84% in black recipients. Within this organ procurement organization, black donation has increased over the past 10 years. Unfortunately, there may be a selection bias at the level of referral for liver transplantation. However, once patients are referred to this center for liver transplantation, the rate of transplantation and survival is similar between white and black patients.

Abstract
The effects of gamma-amino butyric acid (GABA)-ergic drugs on male rabbit sexual behaviour have been evaluated. The GABA(A) agonist 4,5,6,7-tetrahydroxixazolo-5,4c-pyridin-3-ol (THIP), the GABA(B) agonist R-baclofen and the GABA antagonists picrotoxin and bicuculline were used. Injection of THIP, 20 mg/kg, s.c. produced a complete suppression of sexual behaviour and R-baclofen, 2.5 mg/kg, s.c. a significant inhibition. Intraperitoneal injections produced effects at higher doses than did s.c. injections. The inhibition produced by R-baclofen was associated with strong motor effects as shown by the water escape test. It is probable, therefore, that the reduced sexual behaviour observed after treatment with this drug is a consequence of sedative or muscle relaxant effects. By contrast, the dose of THIP that inhibited sexual behaviour had no effect on the water escape test. These results show that the GABA(A) agonist inhibits sexual behaviour in the male rabbit independent of effects on the motor system. The GABA antagonists had marginal or no effects on sexual behaviour. When these data are compared to previous results in the rat, substantial differences are seen. As there are differences between the effects on rat and rabbit sexual behaviour by other types of drugs, it appears that drug action on sexual behaviour cannot be generalized from one species to another.

Abstract
BACKGROUND Tolerance is gaining momentum as an approach to reduce lifelong immunosuppressive therapy while improving transplant longevity. Anti-CD3 immunotoxin (IT), FN18-CRM9, has potential to induce tolerance owing to its exceptional ability to deplete sessile lymph node T cells. However, if initiated at the time of transplantation, alpha-CD3-IT alone elicits a proinflammatory cytokine response, precluding establishment of tolerance. METHODS Four groups of rhesus monkeys received kidney allografts and immunosuppression. Three groups received alpha-CD3-IT alone or alpha-CD3-IT supplemented with 15-deoxyspergualin (DSG) and/or methylprednisolone (MP). One group received alpha-CD3-monoclonal antibody with DSG and MP. Cytokines were measured by enzyme-linked immunosorbent assay. RESULTS Supplementing peritransplant alpha-CD3-IT treatment with a brief course of DSG and MP promoted rejection-free kidney allograft acceptance in 75% of macaques followed for up to 550 days. Among those given alpha-CD3-IT alone or with MP, none were long-term survivors. Tolerance developed after alpha-CD3-IT, DSG, and MP treatment, but not when the unconjugated a-CD3 monoclonal antibody was substituted for IT. Systemic production of proinflammatory cytokines interferon-gamma (IFN-gamma) and tumor necrosis factor-alpha induced after peritransplant alpha-CD3-IT was prevented only in animals given DSG. Despite high levels of interleukin (IL)-12 in the first month after transplant, tolerant recipients exhibited IL-12 resistance, as evidenced by baseline plasma levels of IFN-gamma but elevated IL-4. DSG was shown to inhibit IL-12-driven IFN-gamma production by a mechanism associated with inhibition of nuclear factor kappa-B. CONCLUSIONS In this model, peritransplant induction of tolerance is promoted by efficient elimination of sessile lymph node T cells and control of the proinflammatory IFN-gamma response by a mechanism that appears to involve resistance to IL-12.

Abstract
An adenovirus vector encoding murine Fas ligand (mFasL) under an inducible control was derived. In vivo ectopic expression of mFasL in murine livers induced an inflammatory cellular infiltration. Furthermore, ectopic expression of mFasL by myocytes did not allow prolonged vector-mediated transgene expression. Thus, ectopic expression of functional mFasL in vector-transduced cells does not appear to confer, by itself, an immunoprivileged site sufficient to mitigate adenovirus vector immunogenicity.

Abstract
Low diameter porto-systemic shunts for the treatment of portal hypertension bleeding have emerged as a consequence of the technical development of vascular grafts (PTFE) that allow the use of a narrow lumen. The experience with this kind of operation at the Instituto Nacional de la Nutrición Salvador Zubirán, Mexico City during a 6-year period is reported. There were twenty-seven patients with good liver function (Child-Pugh A-B) were operated or electively, average Age 47.5 years (range 17-71), twenty three patients with liver cirrhosis, one with portal fibrosis and three with idiopathic portal hypertension. Operative mortality: 4%. Rebleeding: 14%. Postoperative encephalopathy was observed in 14 of 27, three of them being grade III-IV (11%). In the remaining 11 cases, it was mild and easily controlled. Postoperative angiography showed shunt patency in 81% of the cases; in 33% of the cases, portal vein diameter reduction was shown, as well as two cases with portal vein thrombosis. In 77% of the cases, adequate postoperative quality of life was observed. Survival (Kaplan-Meier): 86% at 12 months and 56% at 60 months. These kinds of shunts are a good alternate choice for patients considered for surgery, in which other portal blood flow preserving procedures (selective shunts, devascularization with transection) are not feasible.

Abstract
BACKGROUND Mycophenolate mofetil (MMF) prolongs allograft survival in experimental animals, prevents acute rejection in humans, and has recently been approved for use in renal transplantation in combination with cyclosporine. Tacrolimus (Prograf) has been shown to be effective for the prevention and treatment of allograft rejection in liver transplantation. However, there has been limited experience with the combination of tacrolimus and MMF in liver transplantation. METHODS This retrospective pilot study examined the results in 130 primary, consecutive, adult liver transplants under two separate immunosuppressive protocols. Patients in the study group received MMF (1 g p.o. b.i.d.), tacrolimus (0.1 mg/kg p.o. b.i.d.), and a standard steroid taper. MMF was also tapered and then discontinued within 3 months of transplantation. A historical control received tacrolimus (0.15 mg/kg p.o. b.i.d.) and the same steroid taper. RESULTS Pretransplant demographics, including creatinine, were not significantly different between the groups. The 6-month patient and graft survivals of 96.3% (control) versus 92.0% (study) were not significantly different. The incidence of acute rejection was 45.0% in the control group versus 26.0% in the study group (P = 0.03). The study group had a lower incidence of rejection (mean episodes/patient +/- SEM): 0.28+/-0.07 vs. 0.61+/-0.10 (P = 0.007). All of the study group members responded to high-dose steroids. In the control group, three patients required monoclonal antibody therapy and two patients required the addition of MMF. The incidence of cytomegalovirus was similar in the study group and the control group (13.8% vs. 10.0%, P = NS). Early renal function was better preserved in the tacrolimus/MMF group (mean creatinine +/- SEM): 1.09 mg/dl +/- 0.05 vs. 1.51 mg/dl +/- 0.08 at 30 days, P = 0.0001. The study design required dosing with less tacrolimus (mean mg/day +/- SEM), which was achieved at 1 week (23.2+/-0.7 vs. 13.5+/-0.5); 1 month (18.7+/-0.8 vs. 11.4+/-0.5); 3 months (14.5+/-0.6 vs. 9+/-0.5); and 6 months (11.6+/-0.6 vs. 8.2+/-0.6); P = 0.0001, for all time points. CONCLUSION Combination therapy with tacrolimus and MMF may significantly reduce the incidence of acute liver allograft rejection, allow a significant reduction in tacrolimus dosage, and decrease the incidence of nephrotoxicity. Long-term analysis will be necessary to assess any increased risk of opportunistic infections.

Abstract
This study confirms observations made in a former study of plasma of preterm and term newborn infants with intrauterine malnutrition during the first month of life and extends to the lactational period. The free fraction of L-tryptophan, the precursor amino acid of brain serotonin synthesis, is significantly elevated up to 3 months of age. According to previous results, which demonstrated that L-tryptophan and serotonin synthesis are increased in the brain of gestationally malnourished rats, the present data in humans malnourished early in life strongly suggest that the elevation of the free fraction of L-tryptophan in plasma provides an increased amount of the precursor molecule to pass across the blood-brain barrier and activates the synthesis of brain serotonin. Because serotonin has been found to have a possible neurotrophic role in the fetal brain, any alteration of its metabolism in this period could reflect as a permanent change in brain neurogenesis. The data suggest that the free fraction of plasma L-tryptophan may be an indirect marker of changes in brain serotonin synthesis in these patients. Additional data on the functional relevance of the brain serotonergic system in humans are required to support this hypothesis.

Abstract
The results of treatment of hemorrhagic portal hypertension with selective shunts over a 21-year period in a selected patient population are reported. Patients selected for surgical treatment had good cardiopulmonary and renal function, and most also had adequate liver function (141 Child-Pugh class A, 59 class B). Among 734 patients treated surgically for bleeding portal hypertension, 221 had selective shunts (168 distal splenorenal and 53 splenocaval shunts). Global operative mortality (in the 21-year period) was 14% and 12% for Child-Pugh A patients. Operative mortality in Child-Pugh A patients in the last 5 years was only 5%. The rate of rebleeding was 6%, rate of incapacitating encephalopathy was 5%, and rate of survival was 65% at 15 years (last 5 years: 88% at 1 year and 85% at 5 years). Good quality of life was demonstrated in 80% of surviving patients. Shunt patency was 94%. Postoperative portal blood flow changes occurred in 23% of cases (8% diameter reduction, 14% thrombosis). Compared with other forms of therapy (pharmacotherapy, sclerotherapy, and transjugular intrahepatic shunting), only liver transplantation offers similar results for these patients. In countries in which liver transplantation is not routinely performed, shunting with selective shunts is the treatment of choice for patients with good liver function.

Abstract
A major challenge in clinical transplantation today is to design a practical and effective protocol for tolerance induction compatible with cadaver organ transplantation. A preclinical rhesus monkey kidney allograft model using immediate peritransplant anti-CD3 immunotoxin (anti-CD3-IT) and donor bone marrow (DBM) is shown here to induce operational tolerance with prolonged graft survival in the absence of chronic immunosuppressive drugs. Bone marrow harvested from the kidney donor was depleted of mature alloantigen-presenting cells and T cells by removing DR(bright) cells and CD3(bright) cells, respectively. In outbred, major histocompatibility complex-incompatible donor-recipient pairs with high pretransplant mixed lymphocyte response and cytotoxic T lymphocyte precursor activity, four of six allografts survived for periods of 120 days to >1.5 years. Graft acceptance after peritransplant treatment followed robust elimination of both peripheral blood T cells and lymph node T cells. In most recipients given anti-CD3-IT and DBM infusion, anti-donor immunoglobulin G responses were completely inhibited. Microchimerism was observed in all recipients studied, including those not given DBM, but levels of microchimerism did not correlate with graft survival. Anti-CD3-IT induction in combination with modified DBM protocols such as the depletion of mature T cells and DR(bright) antigen-presenting cells may offer new opportunities to improve clinical tolerance protocols beyond those attempted in the clinic to date. Overall, these results with anti-CD3-IT show promise for development of cadaver transplant tolerance induction.

Abstract
Male rabbits were treated with the dopamine releasing drug amphetamine or the dopamine D1/D2 receptor antagonist cis(Z)-flupenthixol. Amphetamine, 1 to 4 mg/kg, had no effect on sexual behavior. Flupenthixol, 2 mg/kg, reduced the proportion of rabbits that ejaculated and the number of ejaculations per test. Lower doses were ineffective. Castrated males were treated with both drugs at two intervals after castration, 19-21 and 27-29 days postcastration, respectively. Amphetamine was without effect while flupenthixol, 1 mg/kg, reduced sexual behavior at the test 19-21 days postcastration. At the second test, sexual behavior was almost completely absent in control animals. Therefore, no further reduction could be observed after treatment with flupenthixol. Another group of animals was castrated and given androgen replacement. Testosterone decanoate was injected once weekly at a dose of 3 mg/kg. This treatment maintained a stable, low sexual activity. In these animals, amphetamine was again ineffective whereas flupenthixol, 1 mg/kg, inhibited sexual behavior. Gross motor function was evaluated in a water escape test. Amphetamine was inactive, and the effective dose of flupenthixol was 10 mg/kg. This dose is far above the dose required for inhibiting sexual behavior. In sum, facilitated dopaminergic transmission does not seem to affect on sexual behavior in the male rabbit, whereas reduced dopaminergic activity disrupts this behavior.
