  • To investigate the effects of T-2 toxin on the blastogenesis of lymphocytes, pathology, hemogram and blood chemistry in the goat, the korean native goats were treated orally with T-2 toxin for 21 days with a dosage of 0.6mg per kg body weight. The results were as follows: 1. The total count of leukocytes and lymphocytes decreased significantly from 14 to 21 days after treatment. 2. Mryeloid: erythroid ratios increased significantly on days 12 after treatment. 3. Delayed-type hypersensitivity skin reactions to tuberculin were reduced predominantly. 4. T-2 toxin induced prolonged prothrombin time. 5. Mitogenic responses of lymphocytes to both lipopolysaccharide and phytohemagglutinin were significantly depressed on days 7 and 14 after treatment. 6. Treatment of T-2 toxin caused marked depletion of lymphocytes in the thymus, mesenteric lymph node, peyer's patchs and spleen.

  • The study was attempted to scrutinize the normal osmotic fragility of erythrocyte in the domestic ruminants, making a comparison with that of human and canine. The animals used in the experiment were apparently healthy adult Holstein cattle, Korean native cattle, sheep (Corriedale) and Korean native goats. Osmotic fragility of erythrocytes was the highest in the Korean native goats, and the next were sheep and Korean native cattle, and Holstein cattle in order. In other words, erythrocytic resistance to osmotic lysis was the strongest in Holstein cattle and the most weak in Korean native goats among the domestic ruminants. In general, resistance of erythrocytes was stronger in human and canine than in the domestic ruminants.

  • The distribution and relative frequencies of the endocrine cells were studied immunohistochemically in the common pancreatic ducts of the Korean native goat with serotonin, glucagon, insulin, BCG, BPP and somatostatin antisera. Serotonin-, glucagon-, BCG-, BPP- and somatostatin-immunoreactive cells were detected in the basal portion of the mucosal gland in the common pancreatic ducts of the Korean native goat but insulin-immunoreactive cells were not detected. The function of these immunoreactive cells and appearance of other immunoreactive cells in the common pancreatic ducts of the Korean native goat were remains unknown.

  • The packed cell volume(PCV) of Korean native goat, volume percentage of red blood cell in whole blood, was reshuffled of 20%, 40% and 60% using autoplasma, and erythrocyte sedimentation rate was measured in Westergren tubes at room temperature ($27{\pm}1^{\circ}C$) and low temperature ($8{\pm}1^{\circ}C$). The sedimentation rates of red blood cell obtained are summarized as follows. The erythrocyte sedimentation rates of Korean native goat are accelerated more at high temperature than low temperature. The erythrocyte sedimentation rates of reshuffled Korean native goat upon time are almost linear for several hours. The erythrocyte sedimentation rates of Korean native goat are settled faster at low PCV than higher PCV, i. e., there is a reverse relationshif between the erythrocyte sedimentation rate and packed cell volume.

  • Four specimens of the odontobutid fish, Odontobutis obscura (Temminck et Schlegel) of the family Odontobutidae were collected for the first time from Koje Island, Kyongsangnam-do, Korea. Odontobutis obscura was easily discriminated from congeners in that this species have no sensory canals at preoperculomandibular and supraorbital pit lines on head and the first band on lateral side of body is extending from the middle of the first dorsal fin. This species distributes in western Japan mainly and Koje island which situates southernmostly in Korean Peninsula. So a new Korean name "Nambangdongsari" is proposed.

  • Objectives The purpose of this study is to investigate the effects of cultivated wild ginseng extract on primary cultured preadipocyte and adipocytes. Methods Diminish preadipocyte proliferation does primary role to reduce obesity. So, preadipocytes and adipocytes were performed on cell cultures with using Sprague-Dawley rats and treated with 0.01-1mg/ml cultivated wild ginseng extract. Result At all concentrations, cultivated wild ginseng extract wasn't show the suppress proliferation of preadipocytes significantly and failed to show effects on decomposition of adipocytes except high dosage. Conclusion Based on these findings, cultivated wild ginseng is not a suitable choice for the treatment of localized obesity.

  • This study was carried out to investigate the origin, insertion, direction of muscle fibers and structure of the ear muscles of the Korean native goat. The description was based on the dissection of fifteen the Korean native goats with embalming fluid. The results were as follows: 1. The ear muscles of the Korean native goat were composed of the M. zygomaticoauricularis, M. scutuloauricularis superficialis, M. scutuloauricularis profundus, M. frontoscutularis, M. interscutularis, M. parietoauricularis, M. cervicoscutularis, M. cervicoauricularis superficialis, M. cervicoauricularis medius, M. cervicoauricularis profundus, M. auricularis profundus posterior and M. parotidoauricularis. 2. The M. frontoscutularis clearly seperated into temporal and frontal parts in 6 cases. 3. The M. scutuloauricularis profundus clearly separated into major and minor parts. 4. The M. zygomaticoauricularis blended with the M. parotidoauricularis near its insertion, but not with the M. scutuloauricularis.

  • This study was carried out to identify anatomical characteristics of the individual bones of the cranium of the Korean native goat. The pars lateralis and pans basilaris of the os occipitale were fused each other, whereas the squama occipitalis articulated with the pars lateralis, forming the sutrue. The sinus sphenoidale was formed in the corpus ossis presphenoidalis. The os prietale was observed as a single bone. In the os frontale, an fossa innominatum was found ventrolateral to the root of processus cornualis, and the orificium orbitale canalis supraorbitalis was also formed on the pars orbitalis. The meatus temporalis was formed in the medial side of the pars squama of the os temporalis. The lamina cribrosa of the os ethmoidale was membrane-like structure with many foramina. The labyrinth ethmoidalis was composed of four endoturbinalia and ten to twelve ectoturbinalia.

  • This paper discusses the role of micro and macrofibers in the workability, compressive strength, and failure of cementitious composites. Workability(flow), compressive strength, splitting strength and fracture mechanism of hybrid fiber reinforced cement composites(HFRCC) have been investigated by means of Korean Standard (KS). The specific blend pursued in this investigation is a combination of polyvinyl alcohol(PVA) and steel cord. It was demonstrated that a hybrid combination of steel and PVA enhances fiber dispersion compared to only steel cord reinforced cement composites and that the brittle and wide cracking was much reduced in HFRCC as expected because in the matrix containing the PVA fiber around the steel cord, a multiple microcracking occurred and the steel cord could sufficiently work for bridging the cracked surface.
