Maintaining internal homeostasis and regulating innate behaviors are essential for animal survival. In various animal species, a highly conserved neuroendocrine system integrates sensory inputs and regulates physiological responses to environmental and internal changes. Diuretic hormones 44 and 31, which are homologs of mammalian corticotropin-releasing factor (CRF) and calcitonin gene-related peptide (CGRP), respectively, control body fluid secretion in Drosophila. These neuropeptides and their receptors have multiple physiological roles, including the regulation of body-fluid secretion, sleep:wake cycle, internal nutrient-sensing, and CO₂-dependent response. This review discusses the physiological and behavioral roles of DH44 and DH31 signaling pathways, consisting of neuroendocrine cells that secrete DH44 or DH31 peptides and their receptor-expressing organs. Further research is needed to understand the regulatory mechanisms of the behavioral processes mediated by these neuroendocrine systems.

The development of life science has given many insights into life phenomenons to mankind. Nevertheless, many questions for various phenomenon in life has not been satisfied. Recently, scientific development in human's knowledge showed the limitation of science comparing With the variety of life phenomenon. The fundmental reason of the limitation is thought that the subject of study in life science has been material, and so life has been thought a matter of material in life science. The thought of Hu Jun about this problem, the nature of living things is an important interest in Korean Traditional Medicine, Haneuihak(韓醫學). In this study, the view of human body and disease of Hu Jun(許浚) about the nature of living things which was appeared in 『Donguibogam』 was illuminated. The content of 『Donguibogam』 was edited in the order of Naekyung(內景篇; internal part of the body)ㆍOuihyung(外形編; external part of the body)ㆍJabbyung(雜病篇; diseases)ㆍTangaek(湯液偏; medicinal decoction)ㆍChimgu(針灸篇; acupuncture and moxibustion). The part of Naekyung(內景篇; internal part of the body) is thesis about basic theories and his thought about human body and life, which was seen in ‘Shinhyungjangbu-do(身形臟腑圖; figure of body and shape, and the organs and viscera)’ㆍthe part of ‘Jeong(精)’ㆍ‘Gi(氣)’ㆍ‘Sin(神)’ theory. In this study, the parts which were related with his view of life were selected and compared with the China philosohy of those days to elucidate what is his thought of life appeared in 『Donguibogam』.

In order to systemically investigate the possibility of using coxsackievirus B3 (CVB3) to deliver foreign genes in vivo, a recombinant strain of CVB3 encoding the renilla gene (CVB3-renilla) was constructed. The recombinant CVB3 resulted in extensive and transient expression of the renilla protein within mouse organs, especially the pancreas. The level of expression was generally dependent upon the viral titer present. Moreover, the CVB3-renilla strain was completely attenuated. Interestingly, the recombinant CVB3 vector was expressed much more strongly in mouse organs than was a comparable adenoviral vector. The CVB3-renilla strain did not express the renilla gene in mice with pre-existing coxsackievirus-specific neutralizing antibodies, but direct organ-specific administration of the virus during open-peritoneum surgery was able to circumvent this immunity. This coxsackievirus vector may represent a useful means for delivering and expressing foreign genes in mouse models in an acute and extensive fashion.

The object of this study was to obtain acute information single oral dose toxicity of Mahwangbujaseshin-tang extracts, with mouse bone marrow cell micronucleus test for detecting possible genotoxicity. In order to observe the 50% lethal dose, approximate lethal dosage, maximum tolerance dosage and target organs, test articles were once orally administered to ICR mice at dose levels of 2000, 1000, 50 mg/kg according to the recommendation of KFDA Guidelines. The mortality and changes on body weight, clinical signs and gross observation were monitored during 14 days after dosing according to KFDA Guidelines with organ weights of 12 types of principle organs. In addition, after twice oral treatment of Mahwangbujaseshin-tang extracts 2000, 1000 and 500 mg/kg, we checked the changes on the number of MNPCE. We could not find any mortality, clinical signs, changes in the body weight and gross findings upto 2000 mg/kg treated group. The limited dosages in rodents except for increases of lymphoid organ weights and hypertrophy encounted as results from pharmacological effects of Mahwangbujaseshin-tang extracts, immune modulator effects with some sporadic accidental findings not toxicological signs. No evidence of increases of MNPCE numbers were also detected in all three different dosages of Mahwangbujaseshin-tang extracts treated mice. The results obtained in this study suggest that the LD50 and ALD of Mahwangbujaseshin-tang extracts in mice were considered as over 2000 mg/kg because no mortalities were detected upto 2000 mg/kg that was the highest dose recommended by KFDA and OECD. And the results of mouse bone marrow micronucleus test of Mahwangbujaseshin-tang extracts is negative results.

To obtain the 50% lethal dose (LD50), approximated lethal dose (ALD) and approximated target organs of 'Mahwangyounpae-tang' for further study like repeat dose toxicity, genotoxicity and reproductive toxicity, single dose toxicity was tested in male ICR mouse according to KFDA Guideline 1999-61 [KFDA, 1999] at a dosage level of 2,000, 1,000, 500, 250 and $125\;mg/kg/10m{\ell}$. In this study, mortalities, clinical signs, body weight changes and body weight gains, gross findings and weight of principal organs were detected during and/or after 14 days of single dosing. After 2 or 3 days of dosing, 1 or 2 animals in 2,000 and 1,000 mg/kg-dosing groups were died. Excitation and leaping response were observed as test article-treatment related clinical signs. These abnormal signs were restricted to 2,000 and 1,000 mg/kg-dosing groups and they were recovered to normal within 4 days after dosing in case of survivors. A significant decrease of body weight were observed in some periods of observation in 2,000 and 1,000 mg/kg-dosing group from 1 days after dosing compared to those of vehicle control group. A significant decrease of body weight gains were observed in observation periods in 2,000 and 1,000 mg/kg-dosing group compared to those of vehicle control group. Hypertrophy of heart and decoloration of kidney were observed as test article-treatment related gross findings. These abnormal findings were restricted to 2,000 and 1,000 mg/kg-dosing groups. A significant increase of absolute and relative heart and kidney weight were demonstrated in 2,000 mg/kg-dosing groups. LD50 in this study was detected as 2,242.42 mg/kg. ALD in this study was detected as 1,000 mg/kg and the target organ was considered as the heart and kidney.

Background : Although patients with stage IV non-small cell lung cancer are known to have a poor prognosis, the prognostic factors for survival have not been well evaluated. Such factors may be different from those for overall survival. This study was performed to analyze the prognostic factors for survuval and the variation of survival according to metastatic organ, in patients with stage IV non-small cell lung cancer. Materials and Methods : From January 1997 to December 2000, 151 patients with confirmed stage IV non-small cell lung cancer were enrolled into this study retrospectively. The clinical and laboratory data were analyzed using univareate Kaplan-Meied and Multivariate Cox regression models. Results : On univariate analysis, age, performance status, serum albumin level, weight loss, forced expiratory volume in one second (FEV1), systemic chemotherapy, the number of metastatic organs and serum lactate dehydrogenase (LDH) level were significant factors (p<0.05). In multivariate analysis, important factors for survival were ECOG performance (relative risk of death [RR]: 2.709), systemic chemotherapy (RR: 1.944), serum LDH level (RR: 1.819) and FEV1 (RR: 1.774) (p<0.05), Metastasis to the brain and liver was also a significant factor on univariate analysis). The presence of single lung metastasis was associated with better survival than that of other metastatic organs (p=0.000). Conclusion : We confirmed that performance status and systemic chemotherapy were independent prognostic factors, as has been recognized. The survival of stage IV non-small cell lung cancer patients was different according to the metastatic organs. Among the metastatic sites, only patients with metastasis to the lung showed bettrer survival than that of other sites, while metastasis of the brain or liver was associated with worse survival than that of other sites.

This report describes the normal radiographic and ultrasonographic morphological features of premature minipigs at 4, 8, 12 and 20 weeks of age. Radiographic examination is a simple diagnostic method used to identify the general morphologic state of major organs and their adjacent structures, and to assess the presence of abnormalities. The parameters for evaluation in plain abdominal radiographs are the degree of diffuse serosal margin details, extent of visualization of each organ, their size, shape, and contour, locations of main organs - such as the liver, stomach, spleen, kidneys, urinary bladder - the distribution of the intestines, and assessment of the retroperitoneal space and its contents. Ultrasonographic examinations are used to investigate their internal condition. The parameters for evaluation in abdominal ultrasonography are echogenicity, echotexture, and size and shape of the main organs such as the liver, spleen, kidney, urinary bladder and gastrointestinal tract. Minipigs had similar findings compared to dogs or cats.
