Glassy cell carcinoma (GCC) of the uterine cervix is a rare and highly malignant tumor, accounting for only 1%~2% of all cervical carcinomas. It is typically composed of malignant cells having a moderate amount of cytoplasm with "ground glass" appearance, distinct cell membranes that stain with eosin or periodic acid-Schiff, and large nuclei with prominent nucleoli. Since its original description in 1956 by Glucletmann and Cherry, 200 - 250 cases of GCC of the uterine cervix have been listed in the literature. We report here the clinicopathological study of one case of glassy cell carcinoma with brief review of the literature.

4.Effects of Adenosine Triphosphate on Relaxation of Rabbit Cavernosal Smooth Muscle.
Korean Journal of Urology 1994;35(8):846-851
Externally applied acetylcholine(Ach) in corpus cavernosum has been shown to cause endothelium dependent smooth muscle relaxation. ATP is accepted as a relaxant of smooth muscle by both a direct action and more powerful indirect action via the endothelial cells. Endothelium-derived relaxing factor(EDRF) is released with stimulation of acetylcholine or other endothelium dependent substances raise cGMP level within the smooth muscle cell and cause relaxation of smooth muscle. EDRF is known as nitric oxide(NO) and its actions are abolished by specific inhibitor of nitric oxide synthesis, such as L-n-monomethyl arginine(L-NMMA) or inhibitors of cyclic GMP synthesis, such as methylene blue(MB). In this study, we evaluated the action of ATP related with NO and compared effect of ATP with acetylcholine and bethanechol chloride in rabbit corpus cavernosal smooth muscle under organ bath. Changes in isometric tension of corporal strips were monitored. With pretreatment L-NMMA or MB, relaxing effects of acetylcholine or bethanechol chloride in corporal strips were completely inhibited, but relaxing effects of ATP were not altered. These data suggested that nitric oxide plays a crucial role in cholinergically induced cavernosal smooth muscle relaxation. ATP mediated rabbit corporal smooth muscle relaxation was not affected by inhibitors of nitric oxide synthesis and independent of cyclic GMP accumulation.

To know the effect of subconjunctival injection of liposome encapsulated cytarabine on proliferation of conjunctival fibroblasts, the conjunctiva was isolated at 180 degrees from the injection site 3 days after subconjunctival injection of the normal saline (control), cytarabine, liposome encapsulated cytarabine, and 1 day after injection of cytarabine, and then those were inoculated in the culture media of fibroblasts. In the case of 3 days after injection of cytarabine, there was 49% and 42% inhibition of proliferation of conjunctival fibroblasts compared with the control respectively. Therefore, the authors concluded that the liposome encapsulated cytarabine is effective on inhibition of proliferation of conjunctival fibroblasts and reduces the frequencies of subconjunctival injection compared with the cytarabine itself.

Journal of Bacteriology and Virology 2011;41(3):133-146
Inflammasome is a cytosolic multiprotein complex to activate caspase-1 leading to the subsequent processing of inactive pro-interleukin-1-beta (Pro-IL-1beta) into its active interleukin-1 beta (IL-1beta) in response to pathogen- or danger-associated molecular pattern. In recent years, a huge progress has been made to identify inflammasome component as a molecular platform to recruit and activate caspase-1. Nucleotide-binding oligomerization domain-like receptor (NLR) family proteins such as NLRP1, NLRP3 or interleukin-1beta-converting enzyme (ICE)-protease activating factor (IPAF) have been first characterized to form inflammasome complex to induce caspase-1 activation. More recently, non-NLR type, pyrin-domain (PYD)-containing proteins such as pyrin or absent in melanoma2 (AIM2) were also proposed to form caspase-1-activating inflammasome machinery with apoptosis-associated speck-like protein containing a CARD (ASC), an essential adaptor molecule. Inflammasome pathways were shown to be crucial for protecting host organisms against diverse pathogen infections, but accumulating evidences also suggest that excessive activation of inflammasome/caspase-1 might be related to the pathogenesis of inflammation-related diseases. Indeed, mutations in NLRP3 or pyrin are closely associated with autoinflammatory diseases such as familial Mediterranean fever (FMF) syndrome or Muckle-Wells syndrome (MWS), indicating that the regulation of caspase-1 activity by inflammasome is a central process in these hereditary inflammatory disorders. Here, recent advances on the molecular mechanism of caspase-1 activation by PYD-containing inflammasomes are summarized and discussed.

OBJECTIVE: The question of whether religion has beneficial or detrimental effects on the mental well-being of the adult individual is debatable. Because most Korean citizens are free to select their own religion, there is a higher proportion of non-believers than believers among the Korean population. The aim of this research was to investigate the association between spiritual values and Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition mental disorders in Korea across all types of belief systems, including Koreans not affiliated with a particular religion. METHODS: The Korean version of the Composite International Diagnostic Interview 2.1 was used to interview 6,275 people across South Korea in 2001. While controlling for age and sex, we used logistic regression to analyze the relationship between mental disorders (both current and past) and the types of religion and spiritual values. RESULTS: Strong spiritual values were positively associated with increased rates of current depressive disorder and decreased rates of current alcohol use disorder. Using "atheist" as the reference category, Catholics had higher lifetime odds of single episodes of depression whilst Protestants had higher lifetime odds of anxiety disorder and lower lifetime odds of alcohol use disorders. CONCLUSION: The results of this study suggest that depressive episodes often lead to a search for spirituality and that religion may be helpful in overcoming depression or becoming less vulnerable to relapsing. The associations between religion, spiritual values, and mental health have not been fully elucidated and warrant further exploration.

BACKGROUND: Through a genome-wide search using the genetic markers(RFLP genetic markers), the familial hypertrophic cardiomyopathy(FHCM) with an autosomal dominant mode of inheritance has been firstly detected to be genetically linked to chromosome 14q1. The subsequent studies have shown that the point mutations at the exons encoding for the head and head /rod junction of the cardiac beta myosin heavy chain(beta-MHC) are the most frequent type of mutation in the FHCM families genetically implicated with a linkage to beta-MHC, whereas the alpha/beta-MHC hybrid gene and a large deletion at the 3' region of beta-MHC gene were also rarely detected. With the other families genetically implicated with the chromosomes 1,11,15,16 and 18, FHCM also manifests locus heterogeneity, a phenomenon in which abnormalities at different genes are involved in different families. In addition, a korean FHCM family with 403Arg-->Gln mutation of beta-MHC gene has been previously found by an american research group. METHODS: For clinical diagnosis, echocardiography and electrocardiography were performed on the individual members of a korean FHCM family. The microsatellite markers(MYO-I,MYO-II) located in the beta-MHC gene region were amplified by PCR(polymerase chain reaction) and the polymorphism was analyzed for the possible linkage to the phenotypic expression of FHCM. Independently, the same PCR products of the exons 13 and 23 were digested with the specific restriction enzymes for the presence of the most frequently reported point mutations of beta-MHC gene (403 and 908 amino acid mutations). Single strand conformation polymorphism(SSCP) of the exon 13 and 23 of the beta-MHC gene was also analyzed of the mobility shift expected if any point mutation is present at these two exons. RESULTS: The inheritance pattern of HCM(hypertrophic cardiomyopathy) in the family is considered as autosomal dominant. In this family(KU 101), one of the microsatellite markers(MYO-II) indicated the possible cosegregation between the allele was also present in the 32-year-old brother of the proband, who reveals no clinical signs of the disease. The other microsatellite genetic marker(MYO-I) was uninformative, without giving the discriminating power to verify the linkage to beta-MHC gene. In the analysis for two common mutations of beta-MHC gene by PCR-RFLP and PCR-SSCP, no evidence was found for 403 and 908 amino acid mutations and any point mutation in the exons 13 and 23. CONCLUSIONS: Based on the linkage analysis using microsatellite genetic markers, there was a possibility that the disease could be linked to an abnormality in the beta-MHC gene of the chromosome 14q1.

BACKGROUND: Our aim was to make a comparative analysis of radiological and clinical outcomes of using either one or two interlocking distal screws on a Polarus intramedullary nail for the internal fixation of humeral shaft fractures. METHODS: From January 2008 to March 2014, we enrolled 26 patients with humeral shaft fractures who were operated on using intramedullary nails. The patients were divided into 2 groups according to how many interlocking distal screws were used to lock the Polarus nail: in group 1, a single interlocking distal screw was used in 12 patients; and in group 2, double interlocking distal screws, in 14 patients. We compared the degree of recovery of the displaced fracture fragments between the two groups. To compare the nonunion and shoulder function, we assessed each patient's modified American Shoulder and Elbow Surgerns (ASES) score. RESULTS: We found that 10 of 12 fractures achieved union in group 1, and 13 of 14 fractures, in group 2. We did not find a meaningful difference in the time to bone union between the two groups. The percentage of recovery of displaced fracture fragments until union was 66.9% for group 1 and 59.41% for group 2. At the final follow-up, we found that the scores for shoulder joint modified ASES was 78.7 for group 1 and 80.7 for group 2. CONCLUSIONS: Our results show that if locked appropriately, even a single screw on a Polarus nail can provide satisfactory radiological union and improved clinical outcome after intramedullary nailing of humeral shaft fractures.
