The development of veterinary dentistry has substantially improved the ability to diagnose canine and feline dental abnormalities. Consequently, examinations previously performed only on humans are now available for small animals, thus improving the diagnostic quality. This has increased the need for technical qualification of veterinary professionals and increased technological investments. This study evaluated the use of cone beam computed tomography and intraoral radiography as complementary... -
BIOCHEMICAL CHARACTERIZATION OF EMBRYONIC CHICK CALVARIAL CELLS
Jae-Hvung Yu, Jung-Kun Kim, Kyung-Suk Cha 대한치과교정학회 The Korean Journal of Orthodontics 8 Pages

Chicken calvarial bone is known to contain various cell types, but their exact composition is unknown. By characterizing the chicken calvarial bone biochemically, it can be used to study biochemical, histochemical actions of bone cells in general. Calvaria of I8-day-old white leg horn embryo was aseptically dissected and bone cell populations were isolated by sequential enzymatic digestion. Histochemical study for osteoclast-like bone cell population was performed with tartrate resistant acid... -

IFNα showed stimulatory effect on alkaline phosphatase activity. The number of calcified nodules was decreased by treatment of cultures with 1ng/ml IL -lβ, 20ng/ml TNFα, and 500 u/ml IFNγ continuously for 21 days, while considerable number of calcified nodules were formed in control group of osteoblast-like cell in culture for 21 days. These results seem to suggest that cytokines may play crucial roles in bone remodeling through the direct action on the osteoblast-like cell. -

Sixty male patients with polysomnographically documented OSA were included in this study. A pair of cephalograrns were obtained in the upright and supine positions. In the supine position, the ANB angle, lower facial height and the cross-sectional area of soft palate increased and there was a decrease in the vertical airway length and oropharynx cross-sectional area. Positional changes did not affect the cross-sectional area of tongue, but the cross-sectional area of the oropharynx decreased in... -

Three-dimensional finite element model was made from adult skull to find desirable direction of retraction force to treat skeletal class II malocclusion. The retraction force of 400g was applied to the first molar. The direction of the force application was 23° downward, parallel, 23° upward and 45` upward to the occlusal plane. The stress distribution and the displacement within the maxilla were analyzed by three-dimensional finite element method. The findings obtained were as follows: 1.... -

교정력은 치아이동과 악골성장을 조절하는 기계적 자극이며, 이러한 기계적 자극에 골세포가 반응하므로써 치조골과 악골의 개조가 일어난다. 이러한 기계적 자극은 크게 압축력과 인장력으로 대별된다. 따라서 본 연구는 인장력 및 압축력의 서로다른 기계적자극이 세포활성에 미치는 차이를 알아보기 위하여 조골세포주 MC3T3-E1세포를 24well 배양접시에 well당 2×104개의 세포를 넣어 배양한 후, 밀생상태가 되었을때 Diaphragm pump을 사용하여, 25g/cm² 및 300g/cm²의 압축력과 -25g/cm² 및 -300g/cm²의... -

The anti-inflammatory, antioxidant, and antimicrobial properties of artemisinin derived from water, methanol, ethanol, or acetone extracts of Artemisia annua L. were evaluated. All 4 artemisinin- containing extracts had anti-inflammatory effects. Of these, the acetone extract had the greatest inhibitory effect on lipopolysaccharide-induced nitric oxide (NO), prostaglandin E2 (PGE2), and pro- inflammatory cytokine (IL-1β, IL-6, and IL-10) production. Antioxidant activity evaluations revealed... -

Very little research has been carried out on safflower seed for the prevention and treatment of the bone deficiency diseases, including osteoporosis, which are supported by scientific evidences. In the present study, 3μl of 0.1% dried crude extract or 2μl of 0.1% dried aqueous fraction were shown to significantly accelerate the rate of differentiation of osteoblast. Also, the crude extract and aqueous fraction increased the [Ca2]i of the cultured osteoblast cells: 3μl of 0.1% dried...
