It is an well established fact that the long term administration of carbon tetrachloride to the experimental animal may cause hepatocellular degeneration which may advance to liver cirrhosis and occasionally even to liver cancer. However, there are not so much reports about the electron microscopic change of various organells in the cytoplasm of hepatocytes, and nearly no reports about the relationship between these structural alterations and functional change. Among the various changes in hepatocytes of the rats of Spraque Dowley which was treated with carbon tetrachloride for long term, the authors studied especially the change in lysosome which has close relationships with the intracellular digestive process. The following results were obtained: 1) The lysosomes of normal hepatocytes were very similar with those observed by other investigators. 2) Generally, the lysosomes of hepatocytes under long term administration of carbon tetrachloride was increased in number and particularly remarkable around the golgi complex and bile canaliculi. 3) There were found some differences in the content of increased lysosomes due to carbon tetrachloride and it was appreciated as a periodical differences of secondary lysosomes which were formed by union of autophagosome and primary lysosome. 4) Considering the fore mentioned results, the increase of lysosomes caused by the administration of carbon tetrachloride seemed to have close relationships with autophagocytosis.

Effects of aerosol on evaporation, freezing and precipitation in a multiple cloud system

Lee, Seoung Soo,Kim, Byung-Gon,Yum, Seong Soo,Seo, Kyong-Hwan,Jung, Chang-Hoon,Um, Jun Shik,Li, Zhanqing,Hong, JinKyu,Chang, Ki-Ho,Jeong, Jin-Yim Springer-Verlag 2017 Climate dynamics Vol.48 No.3

<P>Aerosol effects on clouds and precipitation account for a large portion of uncertainties in the prediction of the future course of global hydrologic circulations and climate. As a process of a better understanding of interactions between aerosol, clouds and precipitation, simulations are performed for a mixed-phase convective multiple-cloud system over the tropics. Studies on single-cloud systems have shown that aerosol-induced increases in freezing, associated increases in parcel buoyancy and thus the intensity of clouds (or updrafts) are a main mechanism which controls aerosol-cloud-precipitation interactions in convective clouds. However, in the multiple-cloud system that plays much more important roles in global hydrologic circulations and thus climate than single-cloud systems, aerosol effects on condensation play the most important role in aerosol-induced changes in the intensity of clouds and the effects on freezing play a negligible role in those changes. Aerosol-induced enhancement in evaporation intensifies gust fronts and increases the number of subsequently developing clouds, which leads to the substantial increases in condensation and associated intensity of convection. Although aerosol-induced enhancement in freezing takes part in the increases in condensation by inducing stronger convergence around cloud bottom, the increases in condensation are similar to one order of magnitude larger than those in freezing. It is found that while aerosol-induced increases in freezing create intermittent extremely heavy precipitation, aerosol-induced increases in evaporation enhance light and medium precipitation in the multiple-cloud system here. This increase in light and medium precipitation makes it possible that cumulative precipitation increases with increasing aerosol concentration, although the increase is small. It is interesting that the altitude of the maximum of the time- and domain-averaged hydrometeor mass densities is quite robust to increases in aerosol concentration. This is because locations of gust fronts and homogeneous freezing do not vary significantly with changing aerosol concentration and this outweighs aerosol effects on hydrometeor size.</P>

The aim of study was to investigate genetic diversity for the calpain/calpastatin gene in three Hanwoo breeds [(Brown (n=62), Brindle (n=81) and Jeju Black (n=30)]. Random samples from three breeds of Hanwoo were selected and genotyped for the 7 SNPs of calpain/calpastatin using TaqMan method. Allele frequencies were investigated for CAPN1/CAST gene. Allele frequency of CAST2 SNP was 0.75, 0.59 and 0.22 for Brown, Brindle and Jeju black, respectively. The CAST3 revealed allele frequency of 0.59 and 0.57 in Brown and Jeju Black, while it showed very low allele frequency (0.07) in Brindle. In particular, favorable allele (G allele) for the CAPN1-2 SNP which was shown a strong association with tenderness in Taurine and Indicine cattle revealed 16% and 17% higher allele frequency in Brown Hanwoo (0.82) comparing Brindle (0.66) and Jeju Black Hanwoo (0.65). AMOVA demonstrated that among population variance occupied only 10% of total variance and among individual variance was 0%, while within individual variance was 90% of total variance. This result showed that population effect contributed very small portion of genetic to these three Hanwoo breeds, while within individual variance contributed large portion of genetic diversity within these Hanwoo breeds. In conclusion, three Hanwoo breeds (Brown, Brindle and Jeju black) showed a genetically homogeneous based on the 7 SNPs of CAPN1/CAST gene and it came from same ancestor to form modern Hanwoo breed.

LEE, Hyeon Yong,HWANG, In Koo,KIM, Dae Ho,KIM, Jung Hwa,KIM, Chang Ho,LIM, Beong Ou,KANG, Tae-Cheon,BANG, Kyung Hwan,SEONG, Nak Sul,LEE, Hak Ju,KIM, Jong Dai,WON, Moo Ho Japanese Association for Laboratory Animal Science 2005 EXPERIMENTAL ANIMALS Vol.54 No.1

<P>Although galanin (GAL) protects hippocampal neurons from ischemic damage, no study has examined ischemia-related changes in endogenous GAL in the hippocampal dentate gyrus. We investigated the chronological changes of GAL, well-known as the potassium channel opener, expression in the dentate gyrus at various times after 5 min of transient forebrain ischemia in gerbils. A few GAL-immunoreactive (IR) neurons were found in the polymorphic layer of the sham-operated group. Three hours after ischemia-reperfusion, the pattern of GAL immunoreactivity was similar to that of the sham-operated group and the number of GAL-IR neurons and immunoreactivity were highest 12 h after ischemic insult. At this time, GAL-IR neurons in the polymorphic layer showed strong GAL immunoreactivity. Thereafter, GAL-IR neurons and immunoreactivity significantly decreased in the dentate hilar region. Four days after ischemic insult, GAL-IR neurons were not detectable. In addition, the results of a Western blot study showed a pattern of GAL expression similar to the immunohistochemical changes. GAL protein content also was highest 12 h after ischemia. In conclusion, the increased expression of endogenous GAL in the dentate gyrus after ischemia is related to response to the ischemic damage.</P>

Radiotherapy-associated Furin Expression and Tumor Invasiveness in Recurrent Laryngeal Cancer

LEE, MYUNGJIN,RYU, CHANG HWAN,CHANG, HYO WON,KIM, GUI CHUL,KIM, SEONG WHO,KIM, SANG YOON Potamitis Press 2016 Anticancer research Vol.36 No.10

<P>Background/Aim: Recurrent laryngeal cancer often shows an aggressive phenotype after radiotherapy and does not respond to conventional therapeutic strategies. In this study, we investigated the contribution of furin to cellular invasiveness in radio-resistant laryngeal cancer. Materials and Methods: Using previously established AMC-HN-3 and AMC-HN-8 cell lines from laryngeal carcinoma patients, recurrent laryngeal cancer models were generated by cumulative irradiation (AMC-HN-3-70Gy and AMC-HN-8-70Gy). Immunocytochemistry and western blotting were used to determine the epithelial-mesenchymal transition (EMT). Invasion capacity was assessed using an in vitro invasion assay. Zymography was used to assess metalloproteinase-2 (MMP-2) activity. Tumor xenografts were developed to compare growth rate and furin expression in vivo. Furin expression in 35 patients (45 samples) with salvage total laryngectomy after radiation-based treatment was assessed by laryngeal cancer tissue microarray. Results: Both AMC-HN-3-70Gy and AMC-HN-8-70Gy cell lines underwent EMT following radiation. However, AMC-HN-3-70Gy cells showed increased cellular invasiveness, whereas AMC-HN-8-70Gy cells showed no difference. AMC-HN-3-70Gy cells also exhibited elevated furin expression with up-regulated expression of the active form of membrane type 1-matrix metalloproteinase (MT1MMP)/MMP-2, whereas AMC-HN-8-70Gy cells did not show significant changes. After administration of a furin inhibitor (chloromethyl ketone (CMK)), AMC-HN-3-70Gy cells showed a significant decrease in MT1-MMP/MMP-2 expression and cellular invasiveness. Nine of 22 samples (40.9%) from salvage total laryngectomy and one of 13 pre-radiation samples (7.7%) had high furin expression. Post-radiation, furin expression increased in seven of 10 patients whose pre- and post-radiation samples were available; all-cancer mortality (three patients) was observed in this group. Conclusion: Together with EMT, furin activity may serve as an indicator of an aggressive cancer phenotype, suggesting that furin is a potentially useful target for recurrent laryngeal cancer.</P>
