Uterine fibroids are the most common benign tumor of the female genital tract. Traditional therapy for symptomatic fibroids has been either myomectomy or hysterectony, depending on whether futhur fertility is desire. A promised new altermative therapy-embolization of the uterine arteries- is now available. A 29 year-old woman was diagnosed of uterine fibroid by ultrasonogram and other techniques. We have experienced one case of uterine fibroid necrosis after transarterial embolization. Now we report a case of uterine artery embolization for treattement of uterine fibriods with a brief review.

OBJECTIVES: Lysosome is the cell-organelle which is commonly used as biomonitoring tool in environmental pollution. In this study, the lysosomal proteomic of the yeast Saccharomyces cerevisiae was analyzed for utilization in the detection of toxic substances in mine water samples. METHODS: This work informs the expression of lysosomal proteomic in yeast in response with toxic chemicals, such as sodium meta-arsenite and tetracycline, for screening specific biomarkers. After that, a recombinant yeast contained this biomarker were constructed for toxic detection in pure toxic chemicals and mine water samples. RESULTS: Each chemical had an optimal dose at which the fluorescent protein intensity reached the peak. In the case of water samples, the yeast showed the response with sample 1, 3, 4, and 5; whereas there is no response with sample 2, 6, and 7. CONCLUSIONS: The recombinant yeast showed a high ability of toxic detection in response with several chemicals such as heavy metals and pharmaceuticals. In the case of mine water samples, the response varied depending on the sample content.

We present a case of a 65-year-old man with psoriasis who developed autoimmune hepatitis (AIH) without receiving immunosuppressive therapy with either anti-tumor necrosis factor-α or methotrexate. The AIH had completely resolved at 2 months after prednisolone and azathioprine therapy. This case confirms the need to consider AIH in psoriasis patients who experience new elevations in liver enzymes. To our knowledge, this is first description of the development of AIH in an immunosuppressant-naïve patient with psoriasis.

BACKGROUND AND PURPOSE: Cutaneous nerve biopsies based on two-dimensional analysis have been regarded as a creditable assessment tool for diagnosing peripheral neuropathies. However, advancements in methodological imaging are required for the analysis of intact structures of peripheral nerve fibers. A tissue-clearing and labeling technique facilitates three-dimensional imaging of internal structures in unsectioned, whole biological tissues without excessive time or labor costs. We sought to establish whether a tissue-clearing and labeling technique could be used for the diagnostic evaluation of peripheral neuropathies. METHODS: Five healthy individuals and four patients with small-fiber neuropathy (SFN) and postherpetic neuralgia (PHN) were prospectively enrolled. The conventional methods of indirect immunofluorescence (IF) and bright-field immunohistochemistry (IHC) were adopted in addition to the tissue-clearing and labeling method called active clarity technique-pressure related efficient and stable transfer of macromolecules into organs (ACT-PRESTO) to quantify the intraepidermal nerve-fiber density (IENFD). RESULTS: The mean IENFD values obtained by IF, bright-field IHC, and ACT-PRESTO in the healthy control group were 6.54, 6.44, and 90.19 fibers/mm², respectively; the corresponding values in the patients with SFN were 1.99, 2.32, and 48.12 fibers/mm², respectively, and 3.06, 2.87, and 47.21 fibers/mm², respectively, in the patients with PHN. CONCLUSIONS: This study has shown that a tissue-clearing method provided not only rapid and highly reproducible three-dimensional images of cutaneous nerve fibers but also yielded reliable quantitative IENFD data. Quantification of the IENFD using a tissue-clearing and labeling technique is a promising way to improve conventional cutaneous nerve biopsies.

Advanced glycation endproducts (AGEs) have been reported to play a role in neointimal formation and increase the rate of in-stent restenosis (ISR) in the diabetic coronary artery disease patients treated with stents, but the potential pathogenic mechanisms of AGEs in vascular smooth muscle cell proliferation remain unclear. We sought to determine the AGEs related pathobiological mechanism of diabetic vasculopathy. Rat aortic smooth muscle cell (RAoSMC) culture was done with different concentrations of AGEs and proliferation was assessed. Immunohistochemistry for receptor of AGEs (RAGE) was performed with human carotid atheroma. Western blotting was performed to assess the activation of MAP kinase system in the cultured RAoSMC. AGEs increased RAoSMC proliferation and were associated with increased phosphorylation of ERK and p38 kinase by time and dose dependent manner. The MAP kinase activity was decreased by RNA interference for RAGE. AGEs stimulation increased reactive oxygen species (ROS) generation in cultured RAoSMC. From this study it is concluded that AGEs played a key role in RAoSMC proliferation via MAP kinase dependent pathways. Activation of vascular smooth muscle cell (VSMC) proliferation by MAP kinase system and increased formation of ROS may be the possible mechanisms of AGEs induced diabetic vasculopathy.

It is well known that developmental delay or arrest occurs before implantation in mamals, which have undergone in vitro culture. Recently, these phenomena are being attributed to oxygen free radicals, and successful cell culture are being obtained by lowering the oxygen environment of in vitro culture. This is due to the fact that the oxygen concentration in the fallopian tube is around 5%, which is lower than the room air 20% concentraition for in vitro culture. Superoxide dismutase(SOD), which are free radical scavenger, were added to early embryo mice culture and compared the free radical level at each stage of development with that of culture in which free radical scavenging agent was not added. The highest free radical level in control group observed in the late 2-cell stage and was markedly decreased if SOD added to culture media. Blastulation rate, hatching rate, and blastomere count as the parameters of embryo development was significantly increased in the experimental group. This study suggests the possibility of improvement in in-vitro embryo culture with media including free radical scavengers.
