Successful male germ cell transplantation requires depletion of the host germ cells to allow efficient colonization of the donor spermatogonial stem cells. Although a sterilizing drug, busulfan, is commonly used for the preparation of recipient models before transplantation, the optimal dose of this drug has not yet been defined in dogs. In this study, 1-year-old mongrel dogs were intravenously...
Animal models of thrombocytopenia are indispensable for evaluating the in vivo efficacy of hemostatic agents, cryopreserved platelets, and artificial platelets, but no large animal models are available. In this study, we generated a swine model of acute thrombocytopenia with prolonged bleeding times by administering the chemotherapeutic drug busulfan. First, we tested multiple doses of busulfan...
Purpose: The aim of this study was to investigate the effect of buserelin on apoptosis of male germ cells induced by busulfan in adult male mice. Materials and Methods: Male adult NMRI mice were divided into four group of eight each. Group 1 (control) administered PBS for 21 days subcutaneously, group 2 given 0.4 mg buserelin for 21 days subcutaneously, group 3 given single dose of 30 mg/kg bus...
Background: Although chemotherapy drugs used in treatment of cancer such as lukemia, prostate and ovary cancer and oligospermia is important contraceptive of this drugs therefore this drugs are author of infertility or low fertility in specimen. In the other hand, the studies show that melatonin is secreted from pineal gland has a direct efficacy on the gonads. The aim of this study was to inve...
BACKGROUND AND OBJECTIVES Busulfan is used as part of a conditioning regimen prior to hematopoietic stem cell transplantation for the treatment of certain cancers and immune deficiency syndromes. Due to its instability in aqueous preparations, busulfan for infusion is prepared from a concentrate and has a relatively short shelf life once prepared. The purpose of this study was to identify the m...
Dibromomannitol (DBM) is a new agent for the treatment of chronic granulocytic leukemia. A propsective evaluation of the drug was undertaken in a randomized comparison with busulfan. Forty previously untreated, Philadelphia chromosome-positive cases were treated, with 20 patients in each treatment group. The protocol provided for continuous maintenance therapy after remission induction, with a ...
BACKGROUND Advancement in the treatment of various types of cancer has led to greater patient survival. These treatments essentially have toxic effects on different kinds of cells, such as germ cells. Infertility as one of the side effects of cancer treatment has changed the quality of life of young cancer survivors dramatically. Melatonin is an antioxidant with receptors in the reproductive sy...
background infertility is a serious social problem in advanced nations, with male factor in half of all cases of infertility. this study was conducted to determine the regenerative effect of bone marrow-derived stem cells in spermatogenesis of infertile hamster. methods twelve adult male hamsters were equally divided into azoospermic and control groups. busulfan was intraperitoneally used for i...
1,7-1 Irpiatirti ¡ol d¡sull'amati-(hepsulfam, NSC 329680) is a new antileukemic agent with close structural similarity to busulfan. The mecha nism of action of hepsulfam is not known and it has recently been entered into Phase I clinical trials by the National Cancer Institute. Waud et al. have recently shown that hepsulfam has good antitumor activity against mouse 1.1210 leukemia in vivo (Wa...
The underlying primary damage to the testis caused by chemotherapeutic regimens during childhood is largely unknown. Xenografting of monkey testes was successfully applied in maturation of juvenile testis to the point of complete spermatogenesis. This allows us to manipulate developing primate testis without direct treatment of patients. This new model is validated establishing the effects of c...
