Background: Chronic renal failure patients with end-stage must be treated with renal replacement methods such as artificial kidneys, renal peritoneum purification or kidney transplant, in which kidney transplant is considered as the optimal method.\r\n', u'Objectives: To study changes of lymphocyte subsets (CD3, CD4, CD8) in kidney transplant recipients.\r\n', u'Subjects and methods: A prospective descriptive study was performed on 80 people including 45 healthy people and 35 patients with transplanted kidney over two years.\r\n', u'Results and conclusion: The average number of lymphocyte subsets in adult healthy people were determined in this study, as follows: TCD4: 540 \xb1 177 tb/\u03bcl, TCD8: 728 \xb1 208 tb/\u03bcl; TCD3: 1389 \xb1 372 tb/\u03bcl; TCD4/TCD8: 0.39 \xb1 0.08; TCD4/TCD3: 0.76 \xb1 0.23 and TCD8/TCD3: 0.76 \xb1 0.23. There was no significant difference in mean number of TCD4 between pre-transplant and 1 year and 2 years post transplantation (p >0.05) but TCD4/TCD8 ratio was significantly decreased at both 1 year and 2 years post-transplantation (p<0.001). TCD4/TCD8 ratio was not significantly different between 1 year and 2 years after transplantation (p >0.05)\r\n', u'\r\n', u'

The foundations of nuclear medicine in Vietnam were established from 1970. Until now, after 48 years of development, in Vietnam, we have some basic equipment including 31 SPECT, 4 SPECT/CT machines, 11 PET/CT scanners, five cyclotrons, and one nuclear reactor.Many nuclearmedicine techniques in diagnosis and treatment have been routinely performed at provincial and central level health facilities such as tumor scintigraphy, thyroid scintigraphy, bone scintigraphy, kidney scintigraphy, cardiac scintigraphy, and radio-isotope therapy with I-131 and P-32. Selective internal radiation therapy with Y-90 microsphere and I-125 radioactive seed implantation has been also successfully applied in some big hospitals. However, there are still many difficulties for Vietnam as the lack of new widely used radioisotopes such as Ga-67, Cu-64, Samarium-153, and Lutetium-177 and the lack of nuclear medicine specialists. In the future, we are putting our efforts on the applications of new isotopes in diagnosis and treatment of cancers (theranostic) like Ga-68-DOTATATE, Lutetium-177-DOTATATE, Ga-68-PSMA, and Lutetium-177-PSMA, equipping modern nuclear medicine diagnostic tools, strengthening the human resources training in nuclear medicine. At the same time, we are trying our best to strengthen the cooperation with international nuclear medicine societies in over the world.
