Mongolian gerbils and Wistar rats were inoculated orally with 240 and 2,500 Toxocara cati embryonated eggs, respectively, to evaluate the larval recovery in different tissues and organs, such as the liver, lungs, heart, kidney, and skeletal muscles after 5, 30, 49, 70, and 92 days post-infection (PI). Larval recovery rates were 1.7-30.0% in Mongolian gerbils on days 5-92 PI and 0.2-3.8% in rats on the same days. These results indicate that Mongolian gerbils and Wi star rats are suitable experimental paratenic hosts for the study of neurological toxocariasis as well as visceral toxocariasis.

Objectives : The objective of this review is to introduce the basic concepts on the febrile disease in the Mongolian Traditional Medicine(MTM). Methods : We comprehensively reviewed related textbooks in Mongolian and articles searched from China National Knowledge Infrastructure(CNKI) on febrile disease about MTM and summarized the pathophysiologic basis of, and treatment principles in MTM. Results and Conclusions : 1. In MTM, there are basic concepts such as theory of Arga-Bilig, theory of five elements, theory of three elements(人體三素), theory of seven constitutions and three discharges(七元三濊). Most of all, theory of three elements, which is about the basic elements of human body in MTM, is important fundamental notions for explaining human physiology and pathology. In MTM, It is explained that the imbalance of three elements, namely khii, shar, bad-kan is the root of all disease. Especially, febrile disease is treated by suppressing activated shar and blood(血液), which have fire characters, and managing various additional symptoms by balancing three elements and eliminating miasma(邪氣), inappropriate substances such as bile water(shar yc, 黃水) or blood stasis(惡血) simultaneously. 2. In MTM, both of internal treatment modalities(various medicinal therapy) and external treatment modalities(physical therapy) have been used for febrile disease. Food therapy and life style modification also have been recognized as important treatment methods. These aspects correspond to wholism theory of Korean Traditional Medicine(KTM). Further studies about details of each treatment methods will discover new applicable treatment method and make broaden the external boundaries of the KTM.

This study was carried out to compare the distribution pattern of the bombesin immunoreactive neurons of the hypothalamic nucleus in the rat and Mongolian gerbil. The bombesin immunoreactive neurons in the rat were located in the dorsal part of the dorsomedial hypothalamic nucleus, but in the Mongolian gerbil in the compact part of dorsomedial hypothalamic nucleus. From this results, we could get an evidence that there were some differences in the distribution of peptide between rat and Mongolian gerbil.

Nepeta sibirica L. or Siberian catmint is a medicinal plant species used in Mongolian traditional medicine for curing human different disorders and veterinary practices. The previous study of the whole plant concentrated on the determination of its essential oil composition and reported that the major ones are sesquiterpenes, including nepetalactone. The aim of this study was to reveal a new biological activity of the above-ground parts of N. sibirica L. and compare the activity of different extracts correlating with the content of biologically active compounds and evaluate their toxicity. For this purpose, anti-oxidative and acetylcholinesterase inhibitory activities of the above-ground parts of N. sibirica L. aqueous and ethanol (EtOH) (40%, 70%) extracts were assayed spectrophotometrically. The aqueous extract showed positive anti-oxidative activity by both tested DPPH and FRAP assays with IC₅₀ 134.24 ± 1.42 mg/mL and FRAP value 1385.15 ± 8.12 µmol/L at 200 ㎍/mL, in contrast to 40% and 70% EtOH extracts. The 70% EtOH extract presented the highest acetylcholinesterase inhibitory activity (IC₅₀ 77.29 ± 0.38 mg/mL) followed by 40% EtOH extract (176.72 ± 0.35 mg/mL) and aqueous extract (275.41 ± 0.23 mg/mL). Total phenolics were found to be gallic acid equivalent, % 3.74 ± 0.05 (70% EtOH), 3.94 ± 0.04 (40% EtOH), and 3.79 ± 0.16 (aqueous), whereas the total flavonoids as a rutin equivalent, % as 2.01 ± 0.12, 1.44 ± 0.17 and 1.99 ± 0.02, each. The aqueous extract showed the best anti-oxidative and lowest activity against the acetylcholinesterase; however, the 70% EtOH extract showed the opposite effects than that of the aqueous. No mortality incidence was visible at various doses, indicating that the oral median lethal dose of aqueous and 70% EtOH extracts were considered greater than 5000 mg/kg. N. sibirica L. belongs to the non-toxic category of the OECD 423 classification.

Objectives : This study was carried out to evaluate the effect of Boyanghwano-tang Extracts on Reversible Forebrain Ischemia in Mongolian Gerbils. Methods : The water content of cerebral edema and the morphologicalㆍneurocytochemistrical change of neuron in MG were implemented to conduct this study. Results : The change rate of water content by ischemia in the normal group was 78.90% on the third day and 79.12% on the seventh day after an attack of ischemia. The rate in the control group was 80.34% and 81.72%. In the sample group the rate was 79.85% and 80.97%. This is a significant result. According to the result of the optical microscopic examination, the cells seen to be continuous and systematic in the pyramidal cells of hippocampus were changed into discontinuous and unsystematic forms in the control group. But compared with the control group, the cells were less damaged in the sample group. Conclusions : The data shows that the effect of Boyanghwano-tang Extracts on Reversible Forebrain Ischemia in MG is a significant result.

This experiment was carried out to investigate the bombesin immunoreactivity in suprachiasmatic nucleus in rat and Mongolian gerbil hypothalamus after colchicine treatment and analyze the morphological difference between rat and Mongolian gerbil which is focused for experimental animal model of neuronal and circulatory diseases. The results were as followings. 1. The shape of suprachiasmatic nucleus was triangle in rat, but oval or kidney-shape in Mongolian gerbil 2. The suprachiasmatic nucleus devided into ventrolateral portion and dorsomedial portion in rat, but dorsolateral portion and ventromedial portion or superior portion and inferior portion in Mongolian gerbil. 3. The area of suprachiasmatic nucleus of rat was greater than one of Mongolian gerbil. 4. The bombesin immunoreactivity showed after colcichine treatment in rat and Mogolian gerbil suprachiasmatic nucleus. 5. The bombesin immunoreactivity was stronger in ventrolateral portion than in dorsomedial portion of suprachiasmatic nucleus in rat, but in ventromedial or inferior portion than in dorsolateral or superior portion of suprachiasmatic nucleus in Mongolian gerbil. 6. The bombesin immunoreactivity showed at the oval, ellipsoid or triangular neurons and varicose nerve terminals in ventrorateral portion of rat, and only nerve terminals in dorsomedial portion of rat suprachiasmatic nucleus. But the bombesin immunoreativity didn't show at neurons of Mongolian gerbil suprachiasmatic nucleus.

Nowadays, mongolian gerbil is widely utilized in the research of brain and water deprivation because of congenitally incomplete Willis' circle, audiogenic seizure in low noise, and special cholesterol metabolism without water absorption for a long time. In this study, we intended to identify the time lapse changes in the general morphoogy and ultrastructure of the catecholaminergic neurons of mongolian gerbil brain in after long-term water deprivation. Fifteen mongolian gerbils were divided into 3 groups (5, 10, and 20-day water deprivation groups), each with 5 mongolian gerbils. Additional 5 mongolian gerbils which received water without limitation were used as a control. The brain sections were immunostained using tyrosine hysroxylase (TH), $ dopamine-\beta-hydroxylase$ (DBH), and phenylethanolamine-N-methyltrasferase (PMNT) antibodies. And immunoreactive cells were observed by electromicroscopy for the ultrastructural changes . The TH-immunoreactive (TH-IR) nerve cells were observed in the para- and peri-ventricular nucleus of the 3 rd ventricle in the hypothalamus and the substantia nigra. The number of TH-IR neurons in these areas was decreased from the 5th day of the water deprivation to the 10 th day and reincreased until 20 th day water deprivation. The shape and density of the dopamine-secreting cells identified by immunohistochemistry showed changes in the continuous water deprivation. Electron microscopy revealed a round nucleus in the neurons of control group but 5-day water deprivation group showed a dense and irregularly shaped nucleus. Also in the 5-day water-deprived group, mitochondria was decreased in number and junctins were disappered. Endoplasmic reticulum, Golgi complex did not show changes after water-deprivation. In this results, we can conclude that dopamine are involved in the water metabolism in mongolian gerbil, and mongolian gerbil could be used as an animal model for the researches of water deprivation.
