Abstract
In vivo administration of recombinant human interferon-gamma, rIFN-gamma, to nude mice bearing human tumor xenografts resulted in a strong induction of HLA-DR expression on the tumor cells in 2 of 3 lines tested. The induction was dose-dependent and declined rapidly after cessation of therapy. IFN-gamma also switched on DQ and DP products when the xenograft cells were treated in vitro. The in vivo alteration of tumor surface properties by rIFN-gamma may have therapeutic implications.

Abstract
Although some manifestations of Lyme disease may be secondary to the presence of B. burgdorferi, the immune system appears to play a significant role in the clinical manifestations of the disease. The humoral response is well characterized, however the cellular response remains poorly defined. To further define cellular immunity in Lyme disease, the responses of lymphocytes from patients with active Lyme disease were assessed to Con a, PHA, PWM, tetanus toxoid, and whole live B. burgdorferi. In addition, the natural killer cell (NK) function of these patients was assayed. As compared to the controls the lymphocyte response to Con A was reduced and the response to PHA was increased. There was a significant proliferative response to B. burgdorferi in all patients with no response in the controls. The responses to PWM and tetanus toxoid were not different in the two groups. NK cell function in the patients with active disease was reduced as compared to the normal controls and patient's who were not clinically active. We conclude that there is a significant alteration in cellular immunity in active LD consistent with a defect in the induction of suppressor cells leading to a vigorous humoral response.

Abstract
A fatal case of infectious mononucleosis occurred in a young adult. Abnormal serological features were noted in his mother, although there was no other family history suggesting an inherited defect of immune response to Epstein-Barr virus (EBV). The cellular infiltrate observed in tissues obtained at necropsy was analysed with a range of specific monoclonal and polyclonal antibodies. Polyclonal plasmacytoid B cell proliferation had occurred in many tissues. These cells were positive for EBV nuclear antigen, but viral particles were not seen on ultrastructural examination, and the virus was not isolated, suggesting a non-permissive infection.

Abstract
A thin-gel isoelectric focusing method has been developed for analysis of protein S-thiolation (formation of mixed disulfides with low molecular weight thiols). The method is rapid and it can be used with 3 to 5 micrograms of a pure protein, or 15 to 20 micrograms of tissue extract protein. It is possible to detect a modification of the protein sulfhydryl by either charged or uncharged thiols, and to determine the quantity of different S-thiolated protein species in a modified sample. The method was used to quantitate the amount of S-thiolation of phosphorylase b in a reaction with oxidized glutathione that produced four S-thiolated forms of the enzyme. The method was also used to detect S-thiolation of two proteins in a cardiac tissue extract treated with diamide. One of the protein bands was shown to be S-thiolated with both cysteine and glutathione, while the other band was S-thiolated only with glutathione.

Abstract
We have studied the activity of recombinant human tumor necrosis factor (rHuTNF) on six different human tumor xenografts derived from primary breast and bowel tumors and maintained by passage in nude mice. When 5 micrograms rHuTNF was given daily intratumorally to mice with established (approximately, 0.5 cm) tumors, total tumor regression was observed by 3-4 weeks in three of six xenograft lines. In a further two lines tumor stasis or significant slowing of growth was seen. This antitumor action was not accompanied by any consistent macroscopic change in the tumor such as necrosis, but histological examination revealed tumor cell degeneration and a large peritumoral infiltration of host inflammatory cells after 4-7 days therapy. In contrast to these data, little effect was seen when the same dose of rHuTNF was administered i.p. to nude mice bearing these tumors. In only two of six lines was any significant slowing of tumor growth seen. A 5-fold increase in the i.p. dose resulted in improved activity on only one of two xenograft lines tested. Efficacy of the i.p. rHuTNF dose could, however, be enhanced by simultaneous administration of human interferon, alpha or gamma. No obvious signs of toxicity were observed at all rHuTNF doses administered and weights of control and treated mice at the end of the experiments were comparable.

Abstract
The immunohistological findings in the thymus after bone marrow transplantation were studied in autopsy samples from 12 patients who had received allogeneic grafts as treatment for acute leukemia. The findings were compared with those in samples from normal individuals and from conventionally treated leukemic patients. The thymuses were hyperinvoluted in all grafted and nongrafted subjects. The remnants were composed of subcapsular and medullary epithelium which expressed the same phenotype as the normal thymus controls. Most samples also contained small remnants of cortical epithelium which lacked normal expression of HLA-DR antigens. The intraepithelial and stromal thymic lymphocytes were virtually all mature T cells, and no immature cortical thymocytes were seen. With the use of HLA-typing methods in 2 recipients of one-haplotype-matched grafts no donor cells could be identified in any of the thymic components. These findings provide no evidence for a functional role for the thymus in the differentiation of donor-derived precursor T cells, at least in the early period after transplantation.

Abstract
A review of the literature reveals that several different phthalic acid esters (PAEs) are capable of causing testicular damage. Phthalate-induced zinc deficiency is consistent with germinal epithelial damage. Among experimental animals, mice perhaps show the greatest sensitivity to phthalate-induced terata, but high doses/exposure are required. Little toxicologic information is available with regard to phthalate-induced effects upon the neonate.

Abstract
Beating neonatal heart cell cultures were treated with diamide or t-butyl hydroperoxide, and changes in glutathione oxidation, cell beating, and protein S-thiolation (protein mixed-disulfide formation) were examined. Both compounds caused extensive oxidation of glutathione. Cells treated with diamide stopped beating within 2 min, and beating returned to normal after 30-45 min. Cells stopped beating 25 min after the addition of t-butyl hydroperoxide, and beating did not resume. t-Butyl hydroperoxide caused S-thiolation of a variety of proteins, but only one protein, of molecular mass 23 kDa, was extensively modified. Diamide caused extensive modification of proteins with molecular masses of 97, 42 and 23 kDa as well as three proteins of about 35 kDa. Though the GSSG content of cell cultures returned to normal by 15 min after diamide treatment. S-thiolation of several proteins persisted. These studies show that S-thiolation of proteins is an important metabolic response in cells exposed to an oxidative challenge by t-butyl hydroperoxide or diamide, and that the specificity of the response depends on the agent used.

Abstract
Protein mixed-disulfides in cultured rat heart cells were analyzed by gel electrophoresis under conditions that eliminated artifactual formation of these protein derivatives. Protein S-thiolation (protein mixed-disulfide formation) was detectable under normal culture conditions. Diamide oxidized intracellular glutathione in these cells and produced extensive protein S-thiolation. The specificity of this protein modification indicates a role in the regulation of cardiac metabolism.

Abstract
Skin biopsies from 3 patients receiving one-haplotype-matched bone marrow grafts have provided a unique opportunity to demonstrate the presence of donor cells in situ using immunohistological techniques and a monoclonal antibody directed against an epitope common to HLA-A2 and HLA-A28 antigens. The infiltrating cells were also analyzed in consecutive tissue sections with a panel of monoclonal antibodies to human leukocyte antigens, T cells, and epidermal Langerhans cells. Most of the infiltrating cells were shown to be T lymphocytes of donor origin, regardless of whether the histological changes were consistant with graft-versus-host disease (GVHD) or were eczematous. Donor T cells were also shown to colonize histologically normal skin soon after transplantation. Epidermal keratinocytes, dermal endothelium, and adnexal structures did not express the donor HLA type (i.e., were host derived) but the origin of the epidermal Langerhans cells could not clearly be established. The data show that donor cells preferentially migrate to certain sites in skin after transplantation and are not always associated with GVHD.

Abstract
The chemical formation, toxicity, and pharmacokinetics of 5-hydroxymethylfurfural (HMF) and certain other decomposition products found in parenteral solutions are reviewed. Heat sterilization-induced hexose decomposition to furan derivatives is promoted at low pH. Based upon infusion studies with rats and dogs, HMF does not appear to be acutely toxic at concentrations ordinarily encountered in parenteral infusion solutions (e.g., 10 mg/liter). Dosages of parenterally administered HMF exceeding 75 mg/kg body wt have led to some toxic effects, including increased activity of hepatic enzymes, altered serum-protein fractions, increased relative spleen weight, and hepatic fatty degeneration. Approximately 50% of parenterally administered HMF is oxidized and eliminated by the kidneys. From a clinical standpoint, the amount of HMF formed as a result of the heat sterilization of parenteral solutions containing hexoses does not seem to pose any significant toxicologic problem.

Abstract
Skin biopsies from leukaemic patients undergoing allogeneic bone marrow transplantations and treated prophylactically with cyclosporin A were analysed using histological, morphometric, and immunohistological techniques. Samples from donors were used to establish normal values. Biopsies taken from recipients two days before grafting were all histologically normal, but on immunohistological staining half of them showed a reduction in the number of epidermal Langerhans' cells and 29% a reduction in T inducer lymphocytes. Thirty two biopsies were taken from patients with rashes at various times after transplantation: 14 showed lichenoid changes consistent with graft versus host disease, three eczematous tissue reactions, two vesicular lesions, and 12 no histological abnormality. One sample showed changes intermediate between the lichenoid and eczematous forms. The numbers of epidermal Langerhans' cells were low during the first few weeks after transplantation and were normal or raised later regardless of histological appearances. Unlike epidermal Langerhans' cells, significant reductions in the numbers of lymphocytes were not seen. Lesions of all histological types contained mixtures of T inducer and T suppressor/cytotoxic cells, although the eczematous and vesicular lesions contained higher proportions of T inducer cells. Epidermal infiltrates invariably contained T suppressor/cytotoxic cells but infiltration of epidermis by T inducer cells occurred only in the presence of normal numbers of epidermal Langerhans' cells. Natural killer cells were not identified. The immunological appearances of the various histological subgroups thus change with time after transplantation.

Abstract
A panel of conventional and monoclonal antibodies was used to examine the immunohistological characteristics of malignant epithelial cells and infiltrating lymphocytes in frozen sections of nasopharyngeal carcinoma (NPC) biopsies from 10 Tunisian patients. Three main categories of cells were identified. (1) Tumour cells which were positive for Epstein-Barr nuclear antigen, HLA-ABC and keratin determinants. In most samples, the tumour cells also expressed variable amounts of HLA-DR antigens. The presence of HLA-DR antigens has not been previously reported in NPC and may be a contributory factor in effecting the transfer of Epstein-Barr virus to the epithelial cells. (2) Infiltrating lymphocytes which were mainly composed of T inducer (T4+) and T suppressor/cytotoxic (T8+) cells although one sample contained predominantly immature T cells expressing the HTA-I+ cortical thymocyte phenotype. Few B cells or natural killer cells were demonstrated. (3) Large HTA-I+ dendritic cells which were invariably present within the tumour masses. These were morphologically and phenotypically similar to antigen presenting Langerhans cells which are usually located in the skin but also found in other epithelial sites. These cells may be a residual population from the normal nasopharynx or represent part of a specific immunological response to the presence of Epstein-Barr virus in the epithelial cells.

Abstract
Epidermal Langerhans' cells (LC) were enumerated in normal human skin from various anatomical sites using a monoclonal antibody (NA1/34) to human thymocyte antigen (HTA-1) and the standard ATPase reaction on frozen sections. The same population of cells was identified with each technique. LC densities were found to be significantly higher in hair bearing skin than in skin from the palm and sole. LC were also identified in hair follicles (where the numbers decreased from the superficial to the deep portions) and sebaceous glands but in no other adnexal structure. Normal numbers were encountered in patients who had received radiotherapy or systemic chemotherapy for malignant disease for periods of greater than two months before death. As LC are important antigen presenting cells, the variation in their density suggests that the immunological properties of normal skin may not be uniform throughout the body. This may be related to the varying anatomical distribution of some skin disorders with an immunological basis.

Abstract
Liver mitochondria isolated from rats treated acutely with glucagon exhibit higher respiration-dependent H+ ion gradients across the mitochondrial inner membrane than mitochondria from control rats. It has been suggested that similar increases in mitochondrial delta pH in situ could stimulate gluconeogenesis, chiefly because the transport of pyruvate into mitochondria would increase in response to the increase in mitochondrial matrix pH. In order to determine whether the increased delta pH observed in vitro in isolated mitochondria also occurs in situ, the effect of glucagon on the pH in the cytosol and mitochondria matrix spaces of isolated hepatocytes was determined. For qualitative results, the spectral responses of intracellularly trapped 6-carboxyfluorescein was used to monitor cytosol pH, while fluorescein-loaded hepatocytes were used to monitor the mitochondrial pH. Hepatocytes were incubated with the diacetate ester derivatives of these dyes. The esters are permeable to the cell membranes, but are rapidly hydrolyzed in the cells. The free unesterified dyes are relatively impermeable to the cell membranes. After being trapped in the cell, 6-carboxyfluorescein remains localized in the cell cytosol, whereas fluorescein is taken up by the mitochondria as a function of the mitochondrial delta pH. In order to quantitate the actual pH in these compartments, the spectral responses (490-465 nm) of 6-carboxyfluorescein-loaded hepatocytes were used to determine the cytosolic pH. Calibration of these responses was obtained within the cell by determination of the dye's differential absorption coefficient (epsilon 490-465 nm) in various high K+ buffers after equilibration of the internal and external pH with valinomycin and the uncoupler 1799. All absorbance values were corrected for dye leakage. Equal hematocrits of unloaded cells were used to correct for absorbance contributions from cellular constituents. The mitochondrial pH was determined by a combination of the indicator dye and [14C]5,5'-demethyloxazolidine-2, 4-dione (DMO) distribution ratio methods. The weak acid DMO freely distributes across the plasma membrane and mitochondrial membrane in whole cells according to the pH gradient across each membrane. Knowledge of the cytoplasmic pH from the 6-carboxyfluorescein data allows the expected distribution of DMO across the plasma membrane to be calculated. The excess accumulation of DMO in intact hepatocytes over that predicted from the plasma membrane pH gradient alone was then used to calculate the pH gradient across the mitochondrial inner membrane. The effects of valinomycin, uncouplers, and hormones on the pH in cytosolic and mitochondrial compartm
