Many investigators reported the mineral corticoid hormon-like action of Glycyrrhizin. The other investigators suggested concerning the glucocorticoid hormon-like action. Authors had been observed the glycogen content of the liver to make sure the relationship between glucocorticoid like action of Glycyrrhizin and glucose metabolism in the liver. There was significant increase in the liver glycogen content in rat fed Glycyrrhizin for two weeks, however it was confirmed that Glucuronic acid combined with Glucuronic was unable to make any influence to glycogen content. The relation concerning the effect of Glycyrrhizin on liver glycogen and its mechanism of action might be needed followup study.

In an attempt to investigate the effect of Beekeumsan on the hemostatic action and isolated uterine muscle, Beekeumsan was administered orally and the bleeding time in mouse tail, prothrombin time in vitro were estimated. Its activity on the isolated uterine muscle in rats were investigated. The following results were obtained; The bleeding time was not shortened, but the plasma prothrombin time in vitro was significantly shortened. The uterotonic action produced by the Beekeumsan was not inhibited by pretreatment of atropine, but was slightly inhibited by cyproheptadine and completely inhibited by pretreatment of diltiazem.

Action recognition has been studied in computer vision field for years. We present an effective approach to recognize actions using a dimension reduction method, which is applied as a crucial step to reduce the dimensionality of feature descriptors after extracting features. We propose to use sparse matrix and randomized kd-tree to modify it and then propose modified Local Fisher Discriminant Analysis (mLFDA) method which greatly reduces the required memory and accelerate the standard Local Fisher Discriminant Analysis. For feature encoding, we propose a useful encoding method called mix encoding which combines Fisher vector encoding and locality-constrained linear coding to get the final video representations. In order to add more meaningful features to the process of action recognition, the convolutional neural network is utilized and combined with mix encoding to produce the deep network feature. Experimental results show that our algorithm is a competitive method on KTH dataset, HMDB51 dataset and UCF101 dataset when combining all these methods.

The studies were conducted to investigate the combined effects of Tonics and Mitomycin C(MMC). The effects of Tonics and MMC on the proliferation of Molt-4 cells, human leukemic cell line, and activation of human lymphocytes were estimated by MTT colorimetric assays. Selected medicines among 9 kinds of Tonics by results of MTT assays were treated with MMC in mice. The Tonics itself enhanced the proliferation of Molt-4, but the anti-proliferative effect of MMC was not intercalated by the combined treatment of Tonic and MMC. Inhibitory action of MMC was augmented by Sa Kun Ja Tang(SKT). This result was due to the inhibition of DNA synthesis. Among 9 kinds of Tonics, Sip Jean Dae Bo Tang(SDT), Saeng Maek San(SMS) and Kwi Bi Tang(KBT) did not inhibit the action of MMC, but activated lymphocytes. When the mice were treated by MMC, the number of leukocytes was decreased significantly at the 1st day, but recovered at the 7th day. In the groups of MMC treated with SDT or KBT, the number of leukocytes was increased significantly than the group of MMC treated only at the 3rd day. Combined treatment of the Tonics(SDT, SMS) and MMC retained the body weight of mice at the level of normal mice. SDT, SMS and KBT did not change the number of plaque forming cells(PFC), but MMC treated group decreased the number of PFC. The combined treatment of MMC and SDT increased the number of PFC significantly than the MMC treated group. SDT, SMS and KBT did not influence the proliferation of T cells, but MMC treated group decreased the proliferation of T cells. The combined treatment of MMC and those tonics increased the T cell proliferation significantly than the MMC treated group. In conclusion, the results presented in this paper suggest that SDT, SMS and KBT can recover the side effects of MMC, such as weight loss, leukopenia and immunosuppresion, without any intercalating the anti-proliferative action of MMC in vivo.

This paper presents shear deformation characteristics in reinforced concrete beams. Based on the relationship between shear and bending moment in beams subjected to combined shear and bending, the behavior of a beam is explicitly divided into two base components of the flexural action and the tied arch action. Transverse elongation of the web and deflections are calculated from shear compatibility condition in a beam and compared with test results.

All organisms are being exposed to harmful factors present in the environmental. The combined action of various factors is a distinguishing feature of modern life. An interaction between two chemicals is considered as synergistic when the effect produced is greater than the sum of the two single responses. The biological effects due to the combined action of ionizing radiation with the other factor are hard to estimate and predict in advance. In the current study, we investigated the synergistic effects between ionizing and $HgCl_2$ using fish hepatoma cells (PLHC-1 cells). The results showed a dramatic decrease of cell viability after simultaneous treatment of PLHC-1 cells with ionizing radiation and $HgCl_2$. Neiither of the two had any cytotoxic effect when treated alone. The cytotoxicity of ionizing radiation was enhanced in the presence of $HgCl_2$. The synergistic effects were observed after exposure of the PLHC-1 cells to ionizing radiation combined with $HgCl_2$. The synergistic interaction was due to an increase of irreversibly damaged cells after the combined exposure. Analysis of the extent of synergistic interaction enables to make quantitative estimation of irreversibly damaged cells after the combined exposure. The present study suggests that PLHC-1 cells can serve as rapid screening tools for detecting the toxicity of harmful factors.

In order to investigate the pharmacological activities of the combined preparation of crude drugs, Chunghyulgangki-Tang was studied. Chunghyulgangki-Tang has been widely used to cerebral apoploxy, hypertension and arteriosclerosis, etc. In this study, water extract of Chunghyulgangki-Tang was conducted in attempt to investigate for analgesic, sedative, antipyretic, isolated ileum and heart, blood vessels and blood pressure action in mice, frogs, rats, guinea-pigs and rabbits. The following results were obtained; Analgesic action by the acetic acid stimulating method in mice was recognized. Sedative activities by the wheel cage method and rotor rod method in mice were shown. Prolonged action against the hypnotic duration induced by thiopental-Na was significantly noted in mice. The effect of antipyretic in endotoxin febrile rats was significantly recognized. Spontaneous motility of the isolated ilem of mice was suppressed and contractions of the isolated ileum of mice and guinea-pigs induced by acetylcholine chloride, barium chloride and histamine were remarkably inhibited. Acceleration of isolated heart motility was shown in frogs. Vaso-dilating and hypotensive actions were recognized in rabbits. According to the above results, effects based on the oriental medicinal references were approximate to the actural experimental results.

The studies were conducted to investigate the combined effects of several combined preparation of crude drugs and mitomycin C(MMC). The combined effects on the proliferation of HepG2, A549, KHOS-Np, A431 and HeLa cells were estimated by MTT colorimetric assays. Sa Kunja Tang(SKT), Boyang Hwanoh Tang(BHT) and Hyulbu Choogo Tang(HCT) inhibited the proliferation of A549 and HeLa cell. The inhibitory action of MMC was increased by the combined treatment of SKT and MMC, and Sa Mul Tang(SMT) and MMC, respectively. When the mice were treated by MMC, the number of leukocyte was decreased significantly at the 3rd day, but recovered at the 7th day. In the groups of MMC treated with SKT or HCT, the number of leukocyte was increased significantly that the group of MMC treated only at the 1st and 3rd day. The combined treatment of SKT, SMT, BHT, HCT and MMC retained the spleen weight of mice at the level of normal mice, but decreased the thymus weight of mice. The combined treatment of SKT, SMT, BHT, HCT and MMC increased the number of PFC significantly than the MMC treated group. The combined treatment of SKT, SMT, BHT, HCT and MMC increased the T cell proliferation significantly thant the MMC treated group.
