  • This experiment is carried out to study alteration of phospholipid compoent in liver, kidney, testis, and brain tissues of male rats which are fed selenium added high fat diets for 7 weeks. The phospholipids of these tissues are analyzed by TLC method. The results are as follows. 1. The growth rate and food intake levels are not affected by selenium-added high fat diets. 2. The levels of total cholesterol, total lipid and TBA are lower in selenium-added diets than selenium free diets 3. The total phospholipid levels of each tissue are kidney > brain > testis > liver and the levels of phospholipid component are Le>Sph>Ce>LLe for kidney and liver, Le>Sph>LLe>Ce for testis and brain.

  • Mitochondria was observed much around the nuclear membrane of liver tissue where the energy metabolism process is active. Testis tissue had a large number of undifferentiated cells, and cristae in Inner membrane of Mitochondria was not observed clearly. Morphological damage occurred first in Inner membrane rather than the outer membrane. The kidney tissue was clearly observed in the form of cristae. Radiation-induced damage occurred at the edges of both ends, and the membrane was observed bursting with the thickness of the outer membrane. Small intestine cells were observed in many mitochondria in the tissues around the villus, where bowel movements were active. Morphological damage occurred with the outer and inner membranes getting tangled. Mitochondria sensitivity to radiation was sensitized in testis and small intestine tissues, and kidney, ovary and liver tissues were found to be resistant.

  • Cancer-testis antigens (CTAs) are a group of tumor associated antigens with a restricted expression pattern in normal gametogenic tissues but expression in a broad range of malignancies. Their expression pattern has made them potential targets for immunotherapy. However, expression of some of these antigens has been demonstrated in normal stem cells as well as cancer stem cells (CSCs). As CSCs have been shown to be sources of metastasis and tumor recurrence, novel therapies are being focused on their eradication. On the other hand, CTA expression in normal stem cells raises the possibility that CTA based immunotherapies cause side effects in normal tissues.

  • Cancer-testis antigens (CTAs) are a group of tumor-associated antigens with more than 140 members whose expression has been shown to be limited to gametogenic tissues and placenta among normal tissues. However, malignant tissues of different origins have shown aberrant and elevated expression of these antigens. Such a pattern of expression endows beneficial properties for use as cancer biomarkers as well as immunotherapeutic targets as a result of the immune-privileged status of the testes. CTAs have been shown to be expressed in pediatric brain tumors, different types of sarcomas, leukemias, and lymphomas as well as neuroblastomas. Although data regarding their expression pattern in childhood tumors are not as comprehensive as for adult tumors, it is supposed that CTA-based immunotherapeutic approaches can also be used for pediatric cancers. However, there are limited data about the objective clinical responses following immunotherapy in such patients. Here we try to review the available information.

  • In order to study the relationships between trace element concentrations of hair and internal organs, autopsy samples of hair, liver, kidney cortex, kidney medulla, heart, lung, spleen, cerebrum, testis and bone from 162 Korean subjects were analyzed for Cd, Hg, Pb and Zn by inductively coupled plasma atomic emission spectrometry. High significant positive correlations were found between the Cd concentration in hair and bone and Pb in hair and lung. Hair Hg levels were highly significantly correlated with organ Hg levels in the liver, kidney cortex, kidney medulla, heart, lung, spleen, cerebrum, testis and bone. And hair Zn levels were highly significantly correlated with organ Zn levels in the kidney cortex, kidney medulla, spleen, testis and bone.

  • Tissue distribution of $SiO_2$ nanopaprticles was investigated in mice after oral administration or skin treatment. ICR Male mice were treated with $SiO_2$ nanoparticles 2.5 g/kg/day for five consecutive days and sacrificed at 24 hours after the last administration. As results, the orally administered $SiO_2$ nanoparticels were distributed in the testis and kidney but not in lung at 24 hours after the last treatment. In case of skin treatment, $SiO_2$ nanoparticles were distributed to lung as well as testis, brain, kidney and liver. The results suggested that $SiO_2$ nanoparticles (12 nm) are easily absorbed through entero-gastric system or skin.

  • We have previously shown that gossypol injection into the stroma of testis was found to effectively inhibit the process of spermatogenesis. In this study, properties and chemistry of blood were investigated weekly in ICR mouse after the injection of gossypol into the testicular stroma(5, 10 or 15mg per kg body weight). There were no significant differences in red blood cell(RBC), hematocrit, white blood cell(WBC), basophils, eosinophils and monocytes during first 4 weeks after injection of gossypol between treatments, but neutrophils increased and lymphocytes decreased, respectively(P<0.05). Total content of protein, albumin and globulin were not different, compared with control. However, the concentration of glucose after injection of gossypol increased significantly(P<0.05). In conculsion, the results of this study indicated that injection of gossypol into stroma of testis might affect both properties and chemistry of blood in mice.

  • Ultrastructural changes of the testis in Pieris rapae L. observed under the electron microscope during the metamorphosis from prepupa to pupa. The peritoneal sheath, epithelium of the follicle and cucticle have the maximum thickness at prepupa stage and afterthen gradually they began to degenerate. The epithelium of the follicle which formed by invagination of the peritoneal sheath is differently differentiationed from the peritoneal sheath and it is similar to the adult's from the pupa 2 days. The cell organelles begin to increase in the cytoplasm of the cyst cell enclosed the sperm bundles at pupa 3 hrs. The electron densed granules which observed in the peritoneal sheath and epithelium of the follicle at prepupa seem to be related with fusion of the testis.

  • The aim of this study was to investigate the biological effects of blood and testis by neutron or gamma-ray irradiation in black mouse. Six-week-old C57BL male mice were irradiated with neutron (flux: 1.036739E+09) or Co60 gamma rays(dose rate: lGy/min.) The irradiation method of animal was abdominal irradiation and dose of irradiation was 10 and 20 Gy added with 5 and 15Gy in neutron irradiation.. After that, the mice were sacrificed 3 days later. Blood and testis were taken and then composition of blood in blood cell were investigated. (omitted)

  • Glycosaminoglycans(PT -Gag) were isolated from the porcine testis. From the PT -Gag. we obtained two different types of Gag fractions using Dowex macroporous Resin MSA-1 column. PT-Gag-1.5% NaCl and PT -Gag-16% NaCl. Various biological activities of the GAGs were examined in aspect of anticoagulant and immunomodulating activity. The anticoagulant activity of the GAGs was evaluated by activated partial thromboplastin time (aPTT ) assay and thrombin time (TT) assay. The GAGs of porcine testis markedly increased the clotting times of both of aPTT and TT. showing that PT-Gag-16% NaCl was more effective than PT-Gag-1.5% NaCl. The immunomodulating activity of the GAGs was examined in relation to regulation of cytokine production of mutine peritoneal macrophages. Treatment with the GAGs promonently enhanced the prodution of cytokines. IFN-${\gamma}$, from macrophages. Taken together. GAGs isolated from porcine testis possess biological functions such as anticoagulant and immunomodulating activity.
