This work was an attempt to propose a model to set up for newly establishment of Nuclear Medicine facility. Medical physicist should establish a major guideline to set up a model of a new nuclear medicine facility; draw the fundamental structure and calculate the corresponding shielding. The various layouts such as the diagnostic (In-Vivo and In-Vitro) and therapeutic layouts of fundamental structure were been made on the primacies as controlled, supervised and non-supervised area according to radiation exposure rate. Some shielding calculations of various facilities such as the diagnostic and therapeutic facility have to provide on instrumentation and radiation safety with the required layout according to maximum activity of radionuclide into the controlled area.

Treatment of atopic dermatitis, which causes human dermal necrosis, depends on strong synthetic antibiotics or staloids. Therefore, sequential prescriptions affect the tolerance of the dermis because absorbed ionics can cause renal and nerve damage. Thus, we have synthesized dermatitis treatment cosmetics ointments by using natural friendly food systems of seed oil such as gamma-linolenic acid (GLA), artificial skin softener, skin cell proliferation agent, and more. The active vitamin derivative was added to the human body ointments as a catalyst diffusion agent. Moreover, the in vitro diagnostic ionic diffusion activity was analyzed with a tattoo skin probe. The trace assay reached the detection limit of 10 mg/L GLA strength for the concentrated range of skin absorption. The results of the assay showed that in vivo real-time skin could be analyzed directly without damage to the cell. This is done with a 30 sec accumulation time, and the measurement potential is 2 v˜–2 V, 35 Hz frequency, with oxidation and reduction scanning stripping and reversible differential wave used. The results of this study can be applied to the development of anti-inflammatory agents that are active in various organ damage preventions, cell proliferation, and in vivo real diagnostic tattoo sensing which was performed.

The importance of radiation damage to the skin and its vasculature was recognized by the early radiologists. In more recent studies, vascular effects were shown to involve the endothelium as well as the surrounding connective tissue. Microvascular changes in the mouse pinna were studied in vivo and recorded photographically over a period of 12-18 months. Radiation treatment at 110 days of age was total body exposure to either 240 rad fission neutrons or 855 rad 60Co gamma rays. After in vivo observations in control and irradiated mice, animals were sacrificed for examination of changes in vascular fine structure. Vessels were selected from regions of specific interest that had been identified on photomicrographs. Prominent ultrastructural changes can be attributed to aging as well as to radiation treatment. Of principal concern were determinations of ultrastructural changes associated with venous dilatations, segmental arterial stenosis and tortuosities of both veins and arteries, effects that had been identified on the basis of light microscopic observations. Tortuosities and irregularly dilated vein segments were related to both aging and radiation changes but arterial stenosis was observed only in irradiated animals.

The differentiation and maintenance of many specialized epithelial structures are dependent on the underlying connective tissue stroma and on an intact basal lamina. These requirements are especially stringent in the development and maintenance of the skin and oral mucosa. The keratinization patterns of thin or thick cornified layers as well as the appearance of specialized functional derivatives such as hair and teeth can be correlated with the specific source of stroma which supports these differentiated expressions.

The in vitro human tumor cloning assay originally described by Salmon and Hamburger has been applied recently to the investigation of differential anti-tumor drug sensitivities over a broad range of human neoplasms. A major problem in the acceptance of this technique has been the question of the relationship between the cultured cells and the original patient tumor, i.e., whether the colonies that develop derive from the neoplasm or from some other cell type within the initial cell population. A study of the ultrastructural morphology of the cultured cells vs. patient tumor has therefore been undertaken to resolve this question. Direct correlation was assured by division of a common tumor mass at surgical resection, one biopsy being fixed for TEM studies, the second being rapidly transported to the laboratory for culture.

Bacterial photosynthetic membranes contain, apart from lipids and electron transport components, reaction centre (RC) and light harvesting (LH) polypeptides as the main components. The RC-LH complexes in Rhodopseudomonas viridis membranes are known since quite seme time to form a hexagonal lattice structure in vivo; hence this membrane attracted the particular attention of electron microscopists. Contrary to previous claims in the literature we found, however, that 2-D periodically organized photosynthetic membranes are not a unique feature of Rhodopseudomonas viridis. At least five bacterial species, all bacteriophyll b - containing, possess membranes with the RC-LH complexes regularly arrayed. All these membranes appear to have a similar lattice structure and fine-morphology. The lattice spacings of the Ectothiorhodospira haloohloris, Ectothiorhodospira abdelmalekii and Rhodopseudomonas viridis membranes are close to 13 nm, those of Thiocapsa pfennigii and Rhodopseudomonas sulfoviridis are slightly smaller (∼12.5 nm).

The bullet-shaped viruses are currently classified together on the basis of similarities in virion morphology and physical properties. Biologically and ecologically the member viruses are extremely diverse. In searching for further bases for making comparisons of these agents, the nature of host cell infection, both in vivo and in cultured cells, has been explored by thin-section electron microscopy.
