This paper dealt with the pathological and clinical findings on the experimentally induced rodenticide (fluoroacetate, zinc phosphide, thallium sulfate, coumarin) and NaCN poisoning of ruminants (Holstein cattle and/or Korean native goat) for the purpose of the diagnosis in the accidental rodenticide poisoning of cattle. The results observed are summarized as follows: Fluoroacetate poisoning (cattle and goat): in the clinical signs, there were depression, convulsion, dyspnea, groan, grinding of the teeth, vomiting, opisthotonus and post-mortem tympany. In the macroscopical findings, the blood was more or less poor coagulative and dark red, bloody fluid with foam in the trachea, hyperemia and hemorrhage of tracheal mucosa and lung, cloudy swelling and hyperemia of kidney, epicardial hemorrhage(cattle), and hyperemia of abomasum, intestine and brain were observed. In the microscopical findings, there were pulmonary edema and hemorrhage, necrosis of convoluted tubular epithelium and interstitial hemorrhage of kidney, focal coagulative necrosis of myocardium, hemorrhage of pancreas and spleen, dilatation of Virchow-Robin space and hyperemia of brain, and necrosis with desquamation of mucosal epithelia of abomasum and upper small intestine. In the histological lesions of the liver, lobular peripheral hyperemia, centrilobular necrosis and cytoplasmic inclusion bodies of the hetatic cells were observed. The cytoplasmic inclusion body of the hepatic cells was not seen in the affected goat, but hydropic degeneration of the hepatic cells was marked. Zinc phosphide poisoning (cattle and goat): clinically, the affected animals died in recumbent position after ataxia, dyspnea and convulsion. In the macroscopical findings, hyperemia and hemorrhage of lung, cloudy swelling and hyperemia of liver and kidney, hemorrhage of spleen (cattle), and catarrh of abomasum and small intestine were observed. In the microscopical findings, necrosis of the convoluted tubular epithelium and hyperemia of kidney, hemorrhage of spleen, hyperemia of lung, hyperemia or hemorrhage of heart, cloudy. swelling and fatty changes of hepatic cells, dilatation of hepatic central vein, hyperemia of brain, and catarrh of abomasal and small intestinal mucosae were observed. Thallium sulfate poisoning (cattle): in the macroscopical findings dark red color of blood, hyperemia and hemorrhage of lung, bloody fluid with foam in the tracheal mucosa, petechiae of tracheal mucosa, cloudy swelling and hemorrhage of liver, necrotic lesions and hemorrhage of renal cortex and epicardial hemorrhage were observed. In the microscopical findings, severe hemorrhages of the lung, cloudy swelling and necrosis of hepatic cells, hyperemia and hemorrhage of liver, focal coagulative necrosis of mycordium, necrosis of the convoluted tubular epithelium and hyperemia of kidney, hyperemia and hemorrhage of spleen and dilatation of Virchow-Robin apace in brain were observed. Coumarin poisoning (goat): the poisoned animals died in the state of groan and depression. In the macroscopical findings, poor coagulation of blood, hemorrhage of lung, cloudy swelling and severe hemorrhages of liver, cloudy swelling and hemorrhage of kidney, abomasal hemorrhage, catarrh of small intestine, and hyperemia and hemorrhage of the other organs were observed, In the microscopical findings, hyperemia and hemorrhage of lung and kidney, cloudy swelling of the convoluted tubular epithelium of kidney, severe hepatic hyperemia, cloudy swelling and hydropic degeneration of heptatic cell, and hyperemia and hemorrhage of brain and spleen were observed. NaCN poisoning (cattle and goat): clinically, there were convulsion, severe dyspnea, paresis of hind limb, depression and then rigor of four limbs. In the macroscopical findings, bright red color of blood, hyperemia and bright and red tinge of lung cloudy swelling of kidney and liver, and hyperemia of abomasum were observed. In the microscopical findings, cloudy swelling and hydropic degeneration of hepatic cell, hyperemia and edema of lung, necrosis and degeneration of the convoluted tubular epithelium and hemorrhage in kidney, dilatation of Virchow-Robin space of brain and hemorrhage of spleen were observed.

$^{86}Rb$ uptake of some organs and tissues, ego both lungs, both renal cortices. small intestine, liver and skeletal muscle were studied in the control and the rabbit subjected to pneumothorax. $^{86}Rb$ in the form of chloride mixed with physiological saline was intravenously. injected. The doses were $100{\mu}c$ for a rabbit. The rabbits were sacrificed at intervals of 10, 20, 40, and 60 seconds after the injection of $^{86}Rb$, by the injection of saturated KCI solution. After sacrification, the organ and tissue sample were quickly removed. $^{86}Rb$ uptake in gm of the organs and tissues were measured. On the basis of uptake value, administered doses and body weight, % dose/gm tissues per 200 gm body weight was calculated. Followings were the results; 1. Pneumothorax resulted in a marked elevation in $^{86}Rb$ uptake value of collapsed lung and returned to normal level lately. 2. Contralateral lung of pnemothorax also showed marked elevation in $^{86}Rb$ uptake value and recovered to normal level. 3. Initial $^{86}Rb$ uptake value of liver, small intestine of the rabbit with pneumothorax showed some elevation as compared to control, but that of late stage were similar with control. 4. Local blood flow determination by means of $^{86}Rb$ uptake were inadequate in the collapsed lung of pneumothorax. 5. It was suggested that the mechanism for the initial elevation of $^{86}Rb$ uptake value in each organs and tissue were different from each other.

Bakground : Complete resection by the surgery has been selected as the treatment of choice in lung cancer patients, but in cases of recurrence after excision or inoperable cases, the importance of anticancer chemotherapy has been emphasized. If one can select a set of the sensitive chemotherapeutic agents before anticancer chemotherapy, it will give more favourable results. Subrenal capsular assay has been recognized as a useful in-vivo chemosensitivity test of thoracic and abdominal tumors and it can be done in a short time for a rapid interpretation of tumor responsiveness to anticancer chemotherapeutic drugs. It has been reported that various kinds of cancer cells can be implantable to the kidney, but so far there is no comparative study of xenogeneic cell implantation on liver, spleen and kidney. The author implanted the human lung cancer cells under the capsule of S.D rat's liver, spleen and kidney respectively and compared the pattern of growth and histology. Material and Method: After incubation of human lung cancer cell line (SW-900 G IV) in RPMI 1640 (Leibovitz L-15 medium) culture media, 3${\times}$3${\times}$3 mm size fibrin clots which contain 108 cancer cells were made. Thereafter the fibrin clots were implanted at subcapsule area of liver, spleen and kidney of S.D. female rat. For immune suppression, cyclosporin-A (80 mg/Kg) was injected subcutaneously daily from post-implantation first day to sixth day. The body weight was measured at pre and post implantation periods. The growth pattern and the size of tumor mass were observed and the pathologic examination and serum tumor marker tests were performed. Result: Body weight increased in both of control and experimental groups. Serum Cyfra 21-1 was not detected. Serum levels of CEA and NSE revealed no significant change. The SCC-Ag increased significantly in implanted group. The growth rate of human lung cancer cells which was implanted on spleen was higher than on liver or kidney. The surface area, thickness, and volume of tumor mass were predominant at spleen. The success rates of implantation were 80% on kidney, 76.7% on spleen and 43.3% on liver. Pathologic examination of implanted tumors showed characteristic findings according to different organs. Tumors that were implanted on kidney grew in a round shape, small and regular pattern. In the spleen, tumors grew well and microscopic neovascularization and tumor thrombi were also found, but the growth pattern was irregular representing frequent daughter mass. Human lung cancer cells that were implanted in the liver, invaded to the liver parenchyme, and had low success rate of implantation. Microscopically, coagulation necrosis and myxoid fibrous lesion were observed. Conclusion: The success rate of implantation was highest in the kidney. And the mass revealed regular growth that could be measured easily. The SCC-Ag was presented earlier than CEA or Cyfra21-1. The Cyfra21-1 was not detected at early time after implantation. The best model for tumor implantation experiment for chemosensitivity test was subrenal capsular analysis than liver and spleen and the useful serum tumor marker in early period of implantation was the SCC-Ag.

Background: Hairy and enhancer of split 1 (Hes-1) protein is a downstream target of Notch signaling and is a basic helix-loop-helix transcriptional repressor. However, definitive evidence for a role in hepatocellular carcinoma (HCC) cells has not been reported. Here, Hes-1 was revealed to an important component of the Notch signaling cascade in HCC cell lines possessing different potential for lung metastasis. Materials and Methods: RNAi mediated by plasmid constructs was used to analyze the role of Hes-1 in MHCC-97L HCC cells by assessing proliferation, apoptosis, cell migration and matrigel invasion following transfection. Hes-1 protein expression analysis in HCC tissue was also conducted by immunohistochemistry. Results: Our studies revealed that Hes-1 was decreased in HCC cell lines with higher lung metastasis potential at both the mRNA and protein levels. Down-regulation of the Hes-1 gene in MHCC-97L cells resulted in increased cell proliferation, reduced apoptosis and increased migration and invasion. Conclusions: Hes-1 has potential prognostic value in post-surgical HCC patients and may be an independent prognostic indicator for overall survival and tumor recurrence. These findings have important implications for understanding the mechanisms by which Hes-1 participates in tumor proliferation and invasion.

This study was designed to define the efficacy of prescriptions of Taeeumin in Sasang constitutional medicine. The twenty four prescriptions registered in Donguisusebowon Sinchuk edition written by Je-ma Lee in 1901 are the targets of this paper. We searched and analyzed original text such as Donguisusebowon Sinchuk edition written in 1901, Donguisusebowon Gabo edition written in 1894, Donguisusebowon Sansang Chobongwon, and posthumous manuscripts left by Je-ma Lee published by the Ministry of Health of North Korea. The pathology of the Taeeumin is classified into four mechanisms those are Esophagus-Cold (Wiwanhan), Cold Lung-Dry (HanpaeJo), Liver-Heat (Ganyeol), and Heat Lung-Dry (YeolpaeJo). The prescriptions of Taeeumin regulate four mechanisms. Twenty four prescriptions of Taeeumin regulate the mechanisms of Wiwanhan, HanpaeJo, Ganyeol, YeolpaeJo and correct the energy-fluid pathology of Taeeumin.

From the study on the relation of voice and O-jang(五臟廳), the conclusion is as follows. The function of breathing out in larynx is involved with lung and kidney. Lung press out the air, at the same time, kidney supports that to maintenance the density of air constantly. So the person who has short breathing can not make strong voice, and also if having a weak kidney in upper Cho[下蕉], their voice will be changed so very softly to cannot make hard type of voice and lingering sounds. Opening and Closing of vocal cords are controled by liver and spleen. when vocal cords are contracted, liver makes tension, whereas spleen does in slackness. So liver is likely to make high-piched sounds in tension of vocal cords, and spleen is the same to do smoothy and husky sounds through relaxing the vocal cords. In the rising condition of liver function, the temp of speech become fast, and more the pronunciation is clearer, it means that the function of thinking by spleen is operated well. Otherwise, indistinct pronunciation means that in the body seup-sa(濕邪) spreads. Also depression of emotion in speech often makes Gi(氣) of heart weaker, whereas it means regular condition of heart including Simpo(心包) that expression of emotion looks happy.

Cystic echinococcosis (CE) caused by Echinococcus granulosus is a major public health problem worldwide, including Turkey. The aim of the current study was to identify the strains and to estimate the potential risk factors of E. granulosus in operated pediatric cases in eastern Turkey. Ten pediatric patients (7 boys and 3 girls) living in rural areas, with ages ranging from 3 to 15 years old and various clinical histories, were included in this study. Eight patients had only liver hydatid cyst, while 1 patient had liver and lung hydatid cyst and the other liver, lung, and spleen, together. There were 2 ruptured liver cysts. After surgery, during follow-up, no increase was observed in hemagglutination levels, there were no mortalities, and there was no evidence of recurrence at 2 years post operation in all patients. Molecular analysis was performed on hydatid cyst samples obtained from the 10 pediatric cases. According to mt-12S rRNA PCR results, all cases were found to be G1/G3 cluster of E. granulosus sensu stricto.

Objectives : This study was to verify the Attributive Channel theory of herbal medicine. Methods : [$^{131}I$]iodohesperetin was synthesized, separated, and refined from hesperetin, the major component of Citrus species, followed by observing the biodistribution in an organism of C57 BL/6 mice with and without Lewis Lung Carcinoma. Results : Iodohesperetin 27.5 mg was obtained through column cliromatography after a reaction with 50 mg of Hesperitin and 8 mg of Nal. The radiochemical yield of [$^{131}I$]iodohesperetin synthesis was 25 % when checked with Radio TLC chromatography. [131I]iodohesperetin was most largely distributed in the stomach, lung and liver of C57BL/6 mouse. The highest %ID/g in stomach was 40 min, in lung and liver was 20 min after injection. The % ID/g of tumor tissue was comparable with that of blood. Conclusions : The fact that [$^{131}I$]iodocurcumin was most largely distributed in the stomach, lung and liver was related with the Attributive Channel theory. And there was no significant finding related to tumor cells.
