Blastocyst Implantation in Rats : A Morphological Approach
Gursoy E.; Bulut H.E.; Basimo?lu-Koca Y. (1998)Very complex cellular events take place at the morphological and molecular levels both in the maternal and embryonic sites during blastocyst implantation. Although the morphological alterations in the gestational stages ... -
Comparison of the Effects of Vasectomy and Experimental Cryptorchidism in Rats: I. Testicular Histology
Günay Y.; Bulut H.E.; Onarlioglu B.; Başimoglu-Koca Y. (1998)The effects of cryptorchidism, one of the most important congenital malformations resulting with the defects in testicular structure thus infertility, is the best known subject in male reproduction. Those best known effects ... -
Comparison of the Effects of Vasectomy and Experimental Cryptorchidism in Rats: II. Epididymal Histology
Başimoglu-Koca Y.; Onarlioglu B.; Bulut H.E.; Gunay Y. (1998)Vasectomy is a male contraception method that its side effects and reversibility rate are still controversial. Effects of vasectomy on epididymal morphology and function, which plays a crucial role in sperm maturation and ... -
Effects of a DNA Demethylating Agent - 5-Azacytidine - on Testicular Morphology during Mouse Embryo Development
Bulut H.E.; Özdemir Ö.; Başimoglu-Koca Y.; Korkmaz M.; Atalay A. (1999)DNA methylation is an epigenetical mechanism that plays crucial roles in cellular differentiation and tissue development in embryogenesis. The aim of the present study was to determine the effects of a demethylating agent, ... -
Effects of experimental diabetes and insulin treatment on rabbit renal morphology: A quantitative and qualitative study
Bulut H.E.; Onarlio?lu B.; Kalo?lu C.; Özdemir Ö.; Ayan S. (2001)Diabetes causes metabolic defects and related vascular alterations such as atherosclerosis. These vascular alterations may also reflect the renal structural degeneration under the influence of diabetes. Therefore, the aim ... -
Effects of Short-Term Hydrocarbon Inhalation on Rat Tracheal Mucosa
Koptagel E.; Bulut H.E. (1998)Hydrocarbons used as solvents in industry are thought to have effects on respiratory system. However, its effect on tracheal morphology and function is poorly investigated. Therefore the present study attempted to investigate ... -
Epidermal Growth Factor Receptor (EGFR) Immunolocalization in the Male Rat Reproductive Tract during Pre-and Postnatal Periods
Kalo?lu C.; Bulut H.E.; Onarlio?lu B. (2000)A number of recent studies suggest the effects of several growth factors as well as genetic factors on the development and differentiation of the testes and excretory ducts. One of the most important growth factors affecting ... -
Increased cell proliferation and R.Msp 1 fragmentation induced by 5-aza-2'-deoxycytidine in rat testes related to the gene imprinting mechanism
Özdemir Ö.; Bulut H.E.; Korkmaz M.; Onarlioglu B.; Çolak A. (2000)DNA methylation is one of the crucial mechanisms for cellular and tissue differentiation during developmental stages in mammals. 5-aza-2'-deoxycytidine, a specific cytosine DNA Methyltransferase inhibitor, is known to cause ... -
Possible Role of K-ras Oncogene in Mutagenic Activity of Ethylnitrosourea on Lymphocyte Hyperproliferation in Rat Colon
Özdemir Ö.; Bulut H.E.; Korkmaz M.; E?ilmez R.; Atalay A. (2001)N-ethyl-N-nitrosourea (ENU) is a potential carcinogenic agent that is commonly used in industry. Therefore the present study aimed to find out the possible effects of this agent on the rat digestive tract especially on the ...
