HE SUCCESS OF autologous bone marrow transplantation ABMT ; for disseminated hematologic malignancies is limited largely by the high incidence of recurrence of the malignancy after ABMT.'.' The recurrences are attributed to the failure of the chemoradiotherapy to eradicate all residual disease and, possibly, to the outgrowth of tumor cells contaminating the infused autologous marrow. Interleukin-2 IL-2 ; and lymphokine-activated killer LAK ; cell therapy has been reported to induce tumor regressions in some patients with advanced cancer.8." Human acute leukemia or lymphoma cells are known and some to be susceptible to LAK cell-mediated lysis, "-L3 patients with advanced lymphoma have been reported to respond to therapy with high-dose IL-2 with or without LAK ~ e l such immunotherapy is potentially Because non-cross-resistant with chemoradiotherapy, IL-2 and LAK therapy administered after ABMT might eradicate residual malignant cells and prevent or delay relapses. Because relapses often occur within the first few months after ABMT, '.' consolidative IL-2 and LAK cell therapy would have to be administered early, before the relapses occur. We have previously reported that IL-2-responsive LAK precursor cells are available in the peripheral circulation as early as 3 weeks after ABMT.I5 Patients thus have the potential to respond immunologically to IL-2 during thisearly posttransplant period. However, high-dosechemoradiotherapy and ABMT may render patients more susceptible to IL-2-associated toxicities. Major toxicities of IL-2 and LAK therapy have included a "capillary-leak' syndrome characterized by oliguria, weight gain, azotemia, and hypotension sometimes leading to respiratory distress, cardiac arrhythmias, myocardial infarction, and even death.8-10.16.17 Moreover, possible myelosuppression by IL-2 is of particular concern after ABMT, because IL-2-induced anemia and thrombocytopenia has been reported." The aim of this study was to determine the toxicity and immunomodulatory effects of IL-2 administered early after ABMT for hematologic malignancies. The IL-2 regimen.
Orders. Therefore, functional alterations of the endotheliumderived NO pathway, especially those involved in the pathogenesis of coronary spasm3 and hypertension, 4 may be due to a lesser endothelial release of NO related to the presence of the 894T allelic form of the eNOS gene, as suggested by the present study. In summary, this study reports the first evidence for an association between the G8943 T polymorphism in the eNOS gene and enhanced vascular reactivity to PE in humans, suggesting that DNA sequence differences in the eNOS gene may affect vascular responsiveness and reactivity to -adrenergic stimulation. However, because the sample of the present study has been highly selected, the sample size is less than in normal gene polymorphism association studies. Thus, another independent study seems to be necessary to verify our present finding. Furthermore, it remains to be determined whether the G894T variant gives rise to direct functional alterations of the endothelium-derived NO pathway or is a genetic marker associated with some causal loci. Functional analysis of the 894T variant and measurement of the NO production must be performed to confirm the results of our study.

Weapons in the delivery of destructive payload [14]. A number of approaches have been developed, which in the context of anti-cancer protocols provide measurable improvements in cell killing. The major categories are radioisotopes, protein toxinenzyme fusions and smallmolecule conjugates. Antibodies are routinely used to concentrate doses of radiation in tissues for both therapeutic and diagnostic purposes. Common isotopes used to this end include iodine-131, yttrium-90, indium-111 and technicium-99. Tumour killing by unlabelled mAbs is limited by the degree of antigen density on the tumour cell and the ability to penetrate tumours adequately. Although radiolabelled mAbs may be less restricted by antigen density in their efficacy they can gain an advantage by a `bystander' effect in killing antigen-negative tumour cells. Conversely, this phenomenon would also be responsible for non-specific toxicity. The two most extensively studied radiolabelled mAbs are Zevalin 90 Y-labelled anti-CD20 ; and Bexxar 131 I-labelled antiCD20 ; , the former receiving recent U.S. Food and Drug Administration FDA ; approval for the treatment of nonHodgkins lymphoma. For therapeutic purposes 90 Y-labelled mAbs may be better debulking agents for larger tumours because of the increased path length of the emission compared with 131 I-labelled mAbs, which may be preferable for targeting post-therapy minimal disease [15]. Protein toxins are a large group derived from a variety of microbial, plant and human sources. Above all other mAb conjugates, these toxins can be engineered directly into the antibody-constant regions, significantly reducing the manufacturing costs. Examples include Pseudomonas exotoxin, which when conjugated to anti-CD22 has been shown to dramatically increase cell killing [16]. For plant toxins, deglycosylated ricin -chain has the longest and most successful history. In one recent report a ricinCD19 conjugate was shown to confer a large increase in the ability of antibody to kill malignant B-cells [17]. The major foreseeable problem with protein toxins is their potential immunogenicity, especially when considering microbial toxins to which an individual may already have been sensitized. An alternative would be to use cytotoxic human proteins. Angiogenin, a human RNase, has been shown to induce apoptosis when delivered into the cytoplasm. In one recent publication, bacterially expressed CD30Langiogenin fusion protein was found to be capable of killing a wide range of CD30 + Hodgkin-derived cell lines [18]. This toxin may represent a clever way to avoid host immune responses. The third payload group comprises toxic small molecules which are usually DNA-complexing agents or inhibitors of the cell cycle. In this situation the antibody conjugate is internalized and the toxic drug liberated after cleavage of a pH- or enzyme-sensitive linker. As mAbs can target chemotherapy exclusively to cancer cells, more potent chemotherapy can be used when attached to mAbs than when administered systemically, for example maytansine conjugates [19]. Small toxic drug molecules have potential advantages: in general they have a negligible immunogenicity.

Statistically Analyses Further evaluations of development of isolated blastomeres were made on 2-cells embryos in different media KSOM + AA ; , KSOM + AA + rhLIF 500 IU ml ; , KSOM + AA + rhLIF 1000 IU ml ; , KSOM + AA + rhLIF 1500 IU ml ; . The statistical analysis was performed by using the SPSS statistical package. The X 2 and logistic regression model tests were used for statistical analysis. A p-value of 0.05 was considered statistically significant. RESULTS General Observation A total of 1028 of 2 cell embryos were collected from 72 stimulated donors 14.21 + 2.2 per donor ; of which, 359 embryos were used for isolation of blastomere. From a total of 712 blastomeres, 47 embryos were damaged and excluded and the remaining 665 were obtained as intact and cultured in different groups. The effect of different concentration of rhLIF on the in vitro development of 2-cell embryos and the percentage and number of 2 cell embryos reaching to stage of 4, 8, 9-16 cells, morula and blastocyst are present in table 1. The effect of different concentration of human leukemia inhibitory factor on in vitro development of isolated blastomeres, the percentage and number of isolated blastomere reaching the stage of 2 cells, 4 cells, 8 cells, 9-16 cells, morulae & blastocysts are present in table 2. DISCUSSION Results of the present study indicate the capacity of the mouse embryo maintained in isolated blastomeres derived from mouse 2-cell embryos for rapid cell division cleavage ; and these blastomeres were able to develop in vitro into apparently normal looking blastocysts. The results of our study coincide with the result of the previous study 4 ; . At least up to 16 cell stages of individual blastomeres were able to develop into apparently normal looking blastocysts. Blastocysts from blastomeres of the parent 2-cells embryos consistently possessed an inner cell mass showing that at this stage of development the mouse blastomere still have the inherent potential to contribute equally to trophoectoderm and inner cell mass 4 ; . It known that the proper embryo of mouse should be derived from the inner cell mass at the early cleavage stage 32, 33 ; and also normal appearing blastocyst have been obtained following nuclear transfer of ICM cells whereas and muse.
Blood cells. The Stanford team has demonstrated that cord blood cells expressing NPM-ALK gain properties necessary for malignant transformation in lymphoma. They are also developing an animal model system by the transplant of NPM-ALK expressing CD34 + cord blood cells into NOD SCID mice. This murine model of human anaplastic large cell lymphoma can then be used to assess the efficacy of novel therapies!

Hematopoietic toxicity. In fact, the use of HGFs may worsen IR- and or chemotherapy-induced residual BM damage by promoting HSC and HPC proliferation and differentiation at the expense of HSC self-renewal 6. This could lead to an augmented exhaustion of HSCs and further compromise the long-term recovery of BM hematopoietic function. Although the residual BM damage is latent, it can manifest as a hypoplastic syndrome at later times or under hematopoietic stress such as subsequent cycles of consolidation cancer treatment or autologous BM transplantation 4, 5. Unfortunately, the mechanisms involved in residual BM injury have not been clearly defined. It has been hypothesized that the defect in HSC self-renewal might be attributable in part to the induction of HSC senescence by IR and or chemotherapeutic agents, because HSCs appear to have a finite ability for self-renewal and may undergo senescence or exhaustion after severe depletion 7-9. However, cellular and molecular evidence for HSC senescence in residual BM injury is lacking. Two recent observations call into question whether HSCs have a limited replicative capacity. First, the observation that a single transplanted stem cell is capable of completely repopulating the host's ablated hematopoietic system, demonstrates the enormous power of HSC self-renewal 10. Second, the calculations of HSC self-renewal based on the competitive repopulating unit have shown that serial transplantation does not result in the reduction of the ability of HSC self-renewal as previously suggested 11. Therefore, it is important to reevaluate whether IR and or chemotherapeutic agents induce HSC senescence, particularly at the cellular and molecular levels. Our recent studies showed that a majority of murine BM hematopoietic cells including HSCs died by apoptosis after exposure to a moderate dose of IR in vitro. However, a subset of these cells survived IR damage up to 35 days in a long-term BM cell culture but lost their clonogenic function 12. These surviving cells exhibited an increased SA--gal activity, a biomaker for senescent cells 13, and and nadolol

In dairy herds where cows are synchronised with IVP4 devices and ODB is administered 24 h after removal of inserts, over 90% of cows are induced to enter oestrus in a 24 period.10 With such a synchronisation program, we have observed considerable pasture damage particularly when cattle are managed on waterlogged pastures. The reduced oestrous detection rate associated with the use of GnRH in the present study was likely to be associated with a reduction in the mounting activity, which could potentially reduce some of the financial losses associated with pasture damage. In addition, utilisation of a timed insemination strategy that eliminates the need for oestrous detection would reduce the labour required. Smaller doses of GnRH have been used in some synchronisation programs in cattle28 but further studies would be required to determine if a reduced dose of GnRH could be used with the treatment protocol used in this study and to compare whether or not there are economic advantages to having a reduction in the proportion of cows that display behavioural signs of oestrus. A positive association between the probability of detecting cows in oestrus following administration of GnRH and calvingto-MSD interval was detected in this study. Expression of oestrus in cows can be affected by the number of ovulations post-partum, 29 a period of progesterone priming before administration of oestradiol30 and whether or not the minimum threshold concentration of oestradiol in plasma required to induce oestrous behaviour has been achieved.27 Rhodes et al 31 also detected a positive relationship between calving interval and the proportion of cows treated for anoestrus that were detected in oestrus following treatment. In the present study cows with longer post-partum intervals may have had more oestrous cycles post-partum and have been less likely to be anoestrus at the commencement of treatment. They may have had greater circulating concentrations of progesterone during the period in which IVP4 were in place, since concentrations of progesterone post-ovulation have been shown to be greater in anoestrous cows following their second induced ovulation compared to following their first induced one.32 Dominant follicles of larger diameter may have developed with increasing post-partum interval since an increase in the diameter of dominant follicles has been observed with increasing post-partum interval in dairy cows.33 An increase in the amplitudes of LH pulses has been detected in cattle between Days 7 and 28 postpartum, 34, 35 while a 4-fold increase in intrafollicular concentrations of oestradiol in large ovarian follicles has been detected in anoestrous beef cows between Days 14 and 28 post-partum.36 Taken together, the results of other studies would suggest that cows with longer post- partum intervals could have larger diameter, more oestrogen-active dominant follicles, which secreted more oestradiol earlier in pro-oestrus. This could account for cows with longer post-partum intervals being more likely to express behavioural signs of oestrus before endogenous secretion of oestradiol was curtailed by the preovulatory surge of LH that was induced by administration of GnRH. The submission rate at the second synchronised oestrus was similar to the submission rate of cows recorded 3 to 6 weeks after MSD 69% ; in a recent survey of reproductive performance of dairy cattle in Australia.37 Recent reports indicate that cows that are retrospectively diagnosed as non-pregnant at the second round of insemination of a controlled breeding program and are not detected in oestrus at the second round of AI have high concentrations of progesterone in milk at the expected and nafcillin.

6354 of both Ku70 and Ku86 are required for effective DEB activity 44 ; . Wang et al. 45 ; has reported that amino acids 371510 of Ku86 interact with Ku70, and that amino acids 179 732 of Ku86 C terminus ; are required for DEB. Our results are in accordance with these findings, because the Ku86v in patient MM cells has C terminus truncation and related decreased DEB activity. Perhaps the most important effect of C terminus truncation on the functional repertoire of Ku86v in patient MM cells is its inability to complex with DNA-PKcs and activate DNA-PKcs, which is essential for repair of DNA damage. Singleton et al. 46 ; have used a series of C-terminal truncated Ku86 mutants to define the C terminus region required for interaction with DNA-PKcs and kinase activation. This report and the current study both demonstrate that truncation of Ku86 C terminus can result in loss of DNA-PKcs binding and kinase activity. Moreover, in their model using CHO mutants with C terminus deletions 46 ; as well as in this study of Ku86v in patient MM cells, this lack of Ku86v complex formation with DNA-PKcs and kinase activity resulted in sensitivity to irradiation, due to decreased DNA repair. We extended these studies to other DNA damaging agents, namely mitomycin C and bleomycin, and showed that sensitivity of MM cells to these agents correlated with Ku86v expression, and conversely, that expression of Ku86 in patient MM cells conferred relative resistance to these treatments. Therefore these studies shed insight into the mechanism of sensitivity to DNA damage in some MM cells and further suggest that Ku86 may be a potential target to overcome resistance to radiation or chemotherapy. Ongoing studies will examine MM cells freshly isolated from patients both before and after treatment with DNA damaging agents, to correlate Ku86 status with response in vivo, and conversely, to determine whether drug resistant cells have increased expression of normal Ku86. Recent reports have also demonstrated increased Ku86 expression, Ku-DEB activity, and DNA-PK activity both in human chronic lymphocytic leukemia cells resistant to radiation and chemotherapy 47 ; and in a murine model of leukemia 48 ; . Finally, the recent observation that Ku86-null ES cells exhibit hypersensitivity to chemotherapeutic agents e.g., etoposide VP-16, bleomycin ; 49, 50 ; further supports the potential utility of targeting Ku86 to modulate chemosensitivity and murine.

There was a significant decrease in mRNA gene expression for im IGF-I in the testosterone-deficient subjects treated with rhIGF-I, similar to that observed in the GnRHa-treated subjects reported previously 15 ; . However, there was a substantial increase in the expression of IGF-I mRNA after rhGH treatment of similar subjects Figs. 3 and 4 ; . mRNA expressions of the androgen receptor, IGFBP-4, myostatin, actin, and myosin are summarized in Table 6. The expression of the androgen receptor was not significantly different from baseline in the hypogonadal men treated with rhIGF-I, yet it was increased during treatment with rhGH. IGFBP-4, on the other hand, was significantly increased in the rhIGF-I-treated group, similar to that in the GnRHa-treated group 15 ; , yet it did not increase during rhGH treatment. The expressions of myostatin, actin, and myosin message were unchanged during systemic rhIGF-I or rhGH treatment in these testosterone-deficient men and naratriptan.
