Female New Zealand white rabbits were subjected to heparin treatment to induce osteoporosis and to observe the effects of calcitonin and tamoxifen treatments on the initiation of osteoporosis, The aim of this study is to investigate zinc-calcium interaction as well as the alterations of plasma biochemical parameters in these animals and, thus, to assist in clinical usage of these drugs. Thirty-two animals were divided into 4 groups and medicated for 8 weeks. The animals in group A were administered heparin (Liquemine) intraperitoneally at the dosage of 1,000 IU/kg/day. The animals in group B were injected the same amount of heparin as that of group A and, in addition, calcitonin at the dosage of 100 IU/kg/day. The animals in group C were medicated the same way as group B, but 2 mg/kg/day tamoxifen (Nolvadex) were orally added to their diet. The animals in last roup were the control, Studied variables, in addition to the biomechanical parameters various bones, a were all electrolytes such as sodium, potassium, chlorine, calcium and phosphorus levels in sera, creatinine, total protein, albumin, alkalene phosphalase, progesteron, estrogen, and globulin concentrations in plasma, and also zinc level in plasma. Heparin and heparin plus calcitonin treatment caused an increase and a decrease in the plasma calcium and zinc levels, respectively, with respect to the control (p < 0.05), whereas tamoxifen treatment in addition to heparin plus calcitonin did not alter the calcium level significantly, but still zinc revel was lower than the control (p < 0.05). Plasma mineral contents except phosphorus in 3 experimental groups decreased significantly with respect to the control. The estrogen and globulin levels in serum in all treated groups increased and these increases were statistically significant with respect to the control, whereas the serum albumin and alkalene phosphatase levels decreased significantly (P < 0.05). The results showed that some alterations in plasma biochemical parameters of heparin-induced osteoporotic animals are observed and some of these alterations are reversed by tamoxifen treatment of these animals.

Investigating the potential of bacillus calmette-guerin vaccine russia strain, cpg oligonucleotides and intravenous immunoglobulin to induce trained immunity in the context of antiviral immunity
Baydemir, İlayda; Gürsel, Mayda; Department of Molecular Biology and Genetics (2020-10-12)
Innate immune cells undergo metabolic and epigenetic reprogramming in response to specific stimuli, that enable a more robust immune response to secondary exposure to a wide variety of pathogens. This process of innate immune memory development has been termed as Trained Immunity (TI). BCG vaccine is one well-known inducer of innate immune memory. In vivo administration of CpG ODNs or Intravenous Immunoglobulin (IVIg) can also exert heterologous anti-microbial protective immunity. In this thesis, we sought ...
Effect of medication on biomechanical properties of rabbit bones: Heparin induced osteoporosis
Akkas, N; Yeni, YN; Turan, B; Delilbasi, E; Gunel, U (Springer Science and Business Media LLC, 1997-11-01)
The aim of this controlled study is to investigate the effect of heparin on osteoporosis initiation and of calcitonin and tamoxifen on the progress of osteoporosis induced by heparin through biomechanical means and, thus, to assist in clinical usage of these drugs, 32 four-month-old female New Zealand white rabbits were divided into four different experimental groups, The animals in group A were administered heparin (Liquemine) intraperitoneally at the dosage of 1000 IU/kg/day, The animals in group B were i...
Genetic and morphometric variation in honeybee (Apis mellifera L.) populations of Turkey
Kandemir, I; Kence, M; Kence, Aykut (Springer Science and Business Media LLC, 2000-05-01)
Six enzyme systems were studied to determine the genetic variability in honeybee populations in Turkey. Ten morphometric characters were also measured to determine the extent of morphometric variation. Out of six enzyme systems, four were found to be polymorphic with 16 allozymes. The average heterozygosity was calculated as 0.072 +/- 0.007. Morphometric and electrophoretic variables were equally effective in discriminating honeybee populations. European and Anatolian honeybees were separated on the first a...
Molecular mechanism of estrogen-estrogen receptor signaling.
Yaşar, P; Ayaz, G; User, Sd; Güpür, G; Muyan, Mesut (2016-12-05)
17 beta-Estradiol (E2), as the main circulating estrogen hormone, regulates many tissue and organ functions in physiology. The effects of E2 on cells are mediated by the transcription factors and estrogen receptor (ER)alpha and ER beta that are encoded by distinct genes. Localized at the pen-membrane, mitochondria, and the nucleus of cells that are dependent on estrogen target tissues, the ERs share similar, as well as distinct, regulatory potentials. Different intracellular localizations of the ERs result ...
