  • 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.

  • Morphological and anatomical evaluation of grafted P. merkusii have been undertaken to obtain the information about compatible and incompatible symptoms of 18 years old grafts based on morphological observation and microscopic analysis. Samples of compatible and incompatible grafts were obtained from previous research conducted by the Silviculture Departement Team in 1994. Result showed that compatible grafts have normal stem form and secondary growth (diameter growth), but some abnormality symptoms like undulated pattern of annual growth rings, phloem thickening and abnormality resin ducts in inner and middle parts of the union area occurred. Incompatible ones showed abnormality of the stem form, cortex-bark necrosis and swelling in the union area. Microscopic observation showed abnormality of all parts of the union, undulated pattern of annual growth rings, phloem thickening, abnormal resin ducts, low numbers and discontinuity of vascular elements in the union area.

  • Nalita wood (Trema orientalis), one of the fastest growing woods in the world, is characterized anatomical, morphological and chemical properties at annual growth ring level in order to investigate as papermaking raw material. The proportion of fibers and vessel was increased with an increase of growth ring (from pith to bark). The fiber length of Nalita was increased with increasing growth ring, and an average fiber length was about 817 um. The average basic density of Nalita was about 0.38 g/cc. The total lignin & holocellulose in Nalita were increased and ash & alcohol-benzene extract decreased from pith to bark. These values were about 23.5 - 24.4 %, 78.1 - 80.1 %, 1.04 - 0.92 % and 2.1 - 1.8 %, respectively. The xylan was the predominant sugar in the hemicellulose of Nalita.

  • 'Hoo Bak' is one of the Chinese crude drugs used mainly to cure a headache, apoplexy and dyspepsia. With regard to the botanical origin of 'Hoo Bak', it has been considered to be Machilus thunbergii of Lauraceae in Korea. But there has no pharmacognostical confirmation on it. To clarify the botanical origin of 'Hoo Bak', the anatomical characteristics of the bark of Machilus thunbergii, Magnolia officinalis and Magnolia obovata were studied. As a result, it was clarified that 'Hoo Bak' from Korea was the bark of Machilus thunbergii of Lauraceae.

  • Color characteristics of pig ${\times}$ wild boar meat were determined with a fiber-optic spectrophotometer. The spectrophotometric characteristic of reduced-myoglobin observed after cutting immediately changed to the spectrophotometric characteristic of oxymyoglobin after 15 minutes of cutting. The spectrophotometry at 400 to 700 nm after 30, 45, 60, 90 and 120 minutes of cutting changed slightly. Compared with M. longissimus thoracis, M. rhomboideus had higher reflectance around 400 nm and from 650 to 1,100 nm and M. spinalis was lower in the visible light region after 60 minutes of cutting. The pig ${\times}$ wild boar meat was similar in reflectance shape with pork but was lower in intensity. The differences depended on the anatomical location. The M. rhomboideus from pig ${\times}$ wild boar had greatly lower reflectance than that from pig, the M. longissimus thoracis reflectance was lower, but M. spinalis reflectance hardly differed. These results showed that pig ${\times}$ wild boar meat had no special characteristic of blooming but had distinguishing characteristic of meat color among anatomical locations.

  • Korean folk medicine 'JagSalNaMu' has been used orally to cure hypercoagulability, thrombosis and tonsillitis. With regard to the botanical origin of 'JagSalNaMu', it has been considered to be Callicarpa species of Verbenaceae, but there was no pharmacognostical confirmation on it. To clarify the botanical origin of 'JagSalNaMu', the anatomical characteristics of the branch of Callicarpa species growing wild in Korea, Callicarpa japonica and C. dichotoma were studied. As a result, it was clarified that 'JagSalNaMu' was the branch of Callicarpa japonica.

  • Korean folk medicine 'JoPabNaMu' has been mainly used to cure removal of fever and neuralgia. With regard to the botanical origin of 'JoPabNaMu', it has been considered to designate the stem of Spiraea species (Rosaceae), but there was no pharmacognostical confirmation on it. To clarify the botanical origin of 'JoPabNaMu', the anatomical characteristics of the branch of Spiraea species growing wild in Korea were studied. As a result, 'JoPabNaMu' was proved to be the branch of Spiraea prunifolia var. simpliciflora.

  • Anatomical comparison of 3 North American species with commercial name of redcedar was executed to provide taxonomic information for prevention of confusion and establishment of sound business transaction in the wood market. Eastern redcedar (Juniperus virginiana) and southern redcedar (Juniperus silicicola) could not be separated on the basis of microstructure and ultrastructure of wood. Western redcedar (Thuja plicata), however, appeared to be obviously separated from eastern and southern redcedar in a number of microscopic and ultramicroscopic features. Useful features for separating these two groups were intercellular spaces in transverse surface, latewood width, radial intertracheid pitting, warty layer and pits with torus extensions in tracheids, ray composition, nodular end walls in ray parenchyma cells, and cross-field pitting.

  • Objectives : Analyze according to types of event causing the adverse outcome due to acupotomy, and discuss problems and safety reqirements to using this therapy in Korea. Methods : Based upon the indication, contraindication, treatment procedures, clinical obsevations, acupotomy-related adverse outcome case reports, the factors of damaging event were classified. Results : The main factors of adverse outcome by acupotomy were anatomical ignorance, contamination of device or hospital staff, failure to notice preexisting disease(cardiovascular disease, hypertension, renal failure, hemophilia, chronic Liver Disease, etc.), unskilled treatment procedures(massive bleeding) and techniques(nerve injury, hepatic and splenic injury, Pneumothorax). Conclusions : It is mandatory to prepare adequate sterilie aseptic technique. The clinician should ensure understand genernal health state of patient and anatomical direction.
