Etymologies are explanations of what our words meant and how they sounded 600 to 2,000 years ago. When Linnaeus in the mid-1700s began naming animals with a binomial nomenclature, he based names on the Latin Grammatical Form. Since many names have Latin or Greek roots, the name for an animal is the same throughout the world because Latin is no longer a spoken language and meanings of names will not evolve or change. In his use of Latin or a Latinized word for the genus and species, Linnaeus used descriptive words that will always be the same. Notwithstanding the importance of etymologies for scientific names, no study has addressed the etymology of scientific names for Korean mammals. Here, we list etymologies for scientific names of 127 mammal species, 84 genera, 32 families, and 8 orders from Korea. The origins of etymologies are mostly based on morphology, color of pelage, behavior, distribution, locality, country name, or a person's name. This paper will be useful for new students and trained scholars studying Korean mammals.

The effect of the nitric oxide synthase(NOS) inhibitor, $N^{G}$-nitro-L-arginine methyl ester (L-NAME), and the prostanoid synthesis inhibitor, indomethacin, on the vasodilatation produced in response to acetylcholine(Ach) on the isolated rabbit renal artery was examined. The vasodilatory reponses to Ach($10^{-8}-3{\times}10^{-5}M$) were completely absent in thevessel which the endothelium had previous been removed. L-NAME($10^{-4}M$) significantly reduced the vasodilatory reponse to the Ach($10^{-8}-3{\times}10^{-5}M$). When L-arginine ($10^{-3}M$) was also present in the organ bath along with L-NAME($10^{-4}M$), this inhibitory effect of L-NAME ($10^{-4}M$) on the vasodilatory response to Ach ($10^{-8}-3{\times}10^{-5}M$) was significantly attenuated, Indomethacin ($10^{-6}M$) did not significantly affect the vasodilatory responses to Ach ($10^{-8}-3{\times}10^{-5}M$). The inhibition by L-NAME ($10^{-4}M$) and indomethacin ($10^{-6}M$) on vasodilatory response to Ach was significantly greater than the inhibition due to L-NAME ($10^{-4}M$) alone. The present study has established that Ach induce relaxation via and endothelium-dependent mechanism, this relaxation to Ach involves both nitric oxide(NO) and prostanoid in the isolated rabbit renal artery.

Background: Partial nerve injury to a peripheral nerve may induce the development of neuropathic pain which is characterized by symptoms such as spontaneous burning pain, allodynia and hyperalgesia. Though underlying mechanism has not fully understood, sensitization of dorsal horn neurons may contribute to generate such symptoms. Nitric oxide acts as an inter- and intracellular messenger in the nervous system and is produced from L-arginine by nitric oxide synthase (NOS). Evidence is accumulating which indicate that nitric oxide may mediate nociceptive information transmission. Recently, it has been reported that NOS inhibitor suppresses neuropathic pain behavior in an neuropathic pain animal model. This study was conducted to determine whether nitric oxide could be involved in the sensitization of dorsal horn neurons in neuropathic animal model. Methods: Neuropathic animal model was made by tightly ligating the left L5 and L6 spinal nerves and we examined the effects of iontophoretically applied NOS inhibitor (L-NAME) on the dorsal horn neuron's responses to mechanical stimuli within the receptive fields. Results: In normal animals, NOS inhibitor (L-NAME) specifically suppressed the responses to the noxious mechanical stimuli. In neuropathic animals, the dorsal horn neuron's responses to mechanical stimuli were enhanced and NOS inhibitor suppressed the dorsal horn neuron's enhanced responses to non-noxious stimuli as well as those to noxious ones. Conclusions: These results suggest that nitric oxide may mediate nociceptive transmission in normal animal and also mediate sensitization of dorsal horn neurons in neuropathic pain state.

This study was carried out to examine the effects of nitric oxide compounds (hemoglobin and L-NAME) on the development of porcine in vitro maturation (IVM) and in vitro fertilization (IVF) oocytes. Cumulus cell free embryos derived from porcine IVM/IVF oocytes were cultured in NCSU23 medium containing 1~5 $\mu\textrm{g}$/$m\ell$ hemoglobin added to 44 and 96hrs in culture times, and in NCSU23 medium containing 0, 10, 50 or 100mM L-NAME. The developmental rates beyond morulae stage in 0, 1 and 5 $\mu\textrm{g}$/$m\ell$ hemoglobin groups add to 44hrs in vitro culture times were 52.4%, 57.6% and 57.4%, respectively. The addition of hemoglobin groups made it slightly higher than the control group. The proportion of embryos developed to morulae and blastocysts in 1 $\mu\textrm{g}$/$m\ell$ hemoglobin add to 96hrs after in vitro culture (70.8%) was a little higher than those of 0 and 5 $\mu\textrm{g}$/$m\ell$ hemoglobin (66.2% and 62.8%). There was no significant difference in all groups (P〉0.05). The developmental rates beyond morulae stage in 0, 10, 50 and 100mM of L-NAME groups add to 96hrs after in vitro culture were 65.2%, 73.5%, 70.1% and 53.3%, respectively 10mM and 50mM L-NAME groups were significantly higher than in 0 and 100mM of L-NAME groups (P＜0.05). In conclusions, these results indicate that L-NAME (10mM, 50mM) can increase the proportion of embryos that develop into morulae and blastocysts but hemoglobin did not affect.

The objective of this study is to analyze habitat distribution on tiger, wolf, and leopard in Joseonwangjosilok. Nowaday, we only come to meet these kind of animals at the historical records because of haman-induced habitat encroachment. Historically, extinct animal became an object of game by people. So, we try to get distribution information for restoration on historical extinct animals. We made distribution map by constructing 402 counts on tiger(350), leopard(51) and wolf(1) recordsfrom 14th to Early 20th century for study. Analyzing historical materials, criteria for data analysis took into account objectivity, location information, accuracy for extinct animals. We carried out location identification of animals by using geocoding comparing with geographical name of the Joseon Dynasty period, topographic map of time under the rule of Japanese imperialism, present place name and historical materials. Database items are constructed 20 types for example appearance year of animal, population, location, damage, etc. As a result of analysis for appearance regions, tigers were recorded in capital area of higher density population intensively, and also were frequently seen at Daegu, Andong etc. Leopard and wolf were founded at regionally Gyeonggi-do and Jinju with limitation, relatively seen a few number. The reason of the appearance records like this, tiger prefer game of open and water-front area in near human residential area, there are lots of historical records such as 'Hosang'(mourning someone who killed by Tiger) and hunting. But leopard and wolf inhabit rocky area and dense forest, the reason why they made a few contact with human. Results of this are expect to be applicable restoration research for extinct animal by providing for populations, habitat environments and distribution information.

The planning of any experiment or trial involving the use of animal (material) requires the most detailed and careful consideration of the wide variety of species and strains that are now available. Unfortunately, although many research workers carefully define their requirements with respect to chemicals or complicated laboratory equipment, often they appear to be unaware of the specifications that should be similarly applied to laboratory animals and end up simply asking for a white mouse！ The aim of any user of laboratory animals should be to achieve maximum accuracy with the minimum number of animals, and it is, therefore, essential that careful consideration should be given to the choice of the animal(Bleby J, 1987). The first step when selecting an experimental animal is to specify the type needed, taking into account the following factors: 1. species, 2. breed or strain, and 3. quality, especially with respect to health and genetical status. The correct choice of species cannot be emphasized too strongly and failure to do so can sometimes have dire consequences, frequently very expensive in financial terms and sometimes extremely tragic in manifestations of human and animal suffering. In this paper, we reorganized a lot of collected articles described previously for common and scientific names of amphibians, domestic animals, birds, invertebrates, mammals, reptiles, and aquaculture as mentioned in the text.

The effect of nitric oxide synthase(NOS) inhibita, $N^G$-nitro-L-arginine-methyl ester(L-NAME) and prostanoid synthesis inhibiter, indomethacin on the photorelaxation, when was exposed to the long-wave length UV-light, was examined on the precontraction by the phenylephrine in the isolated pig renal artery. 1. UV-light relaxed both with-endothelium and without-endothelium in the pig renal arterial ring contracted by the phenylephrine. The magnitude of photorelaxation was dependent on the exposure time for UV-light. 2. UV-Iight induced relaxation was inhibited by L-NAME and indomethacin on the precontraction by the phenylephrine in the isolated pig renal artery. 3. UV-Iight induced relaxation was inhibited by methylene blue on the precontraction by the phenylephrine in the isolated pig renal artery. These results suggest that UV-light induced photorelaxation may be due to cGMP involved both nitric oxide and prostanoid on the precontraction by the phenylephrine in the isolated pig renal artery.
