The present study was undertaken to investigate the effect of bee venom acupuncture therapy on the hair follicle growth by macroscopic, microscopic and immunohistochemical observation of skin 10 and 17 days after treatment. The results were as follows : Macroscopic hair follicle growth of 0.2 ml S.B.V. acupuncture treated group was more prominent than those of 0.1 ml S.B.V. acupuncture treated group and control group. Microscopic observation indicated that the hair follicle growth of control group reached anagen phase IV of hair growing cycle, and that of 0.1 ml and 0.2 ml S.B.V. acupuncture treated groups reached anagen phase VI and catagen, respectively. Immunohistochemical observations of the expression of various cytokines, enzymes and receptors in association with hair follicle cycle after local treatment of S.B.V. acupuncture therapy are as follows: Expression of fibroblast growth factor was more intense in epidermis and outer root sheath in 0.2 ml S.B.V. acupuncture treated group than that of 0.1 ml S.B.V. acupuncture treated group and control group. Expression of epidermal growth factor was more intense in bulge and outer root sheath in 0.2 ml S.B.V. acupuncture treated group than that of 0.1 ml S.B.V. acupuncture treated group and control group. Expression of c-kit receptor was more intense in epidermis, bulge and outer root sheath in 0.2 ml S.B.V. acupuncture treated group than that of control group. Expression of vascular endothelial growth factor was more intense in epidermis, bulge and outer root sheath in 0.2 ml S.B.V. acupuncture treated group than that of control group. Expression of protein kinase C-${\alpha}$ was more intense in epidermis, bulge and outer root sheath in 0.2 ml S.B.V. acupuncture treated group than control group. It is concluded that bee venom acupuncture therapy promoted the expression of various cytokines, enzymes and receptors related to the hair growth cycle for hair growth. This findings indicates that bee venom acupuncture therapy is applicable to the treatment of hair loss.
Anatomical and physiological studies of sink tissues are required for better understanding the biological plant growth system and energy metabolism Anatomy of root growth zones of two genotypes of tall fescue (Festuca arundinacea Schreb.) receiving 50 or 200 ppm N were determined, Cross-sectional anatomy and cells responses of root growth zones were observed and examined. Rapid radial root expansion occurred within the first 1.0 mm from root apex, and then increased gradually for both genotypes and N levels. Another increase in diameter occurred at high N after cell elongation slowed near 3.0 mm. Area of the central cylinder cell increased rapidly near the root apex. However, it then decreased again about 1.0 to 1.5 mm from the apex, perhaps because of pressure from the rapid increase of root diameter due largely to an increasing proportion of cortex and epidermis or hypodermis in the distal portion of the root growth zone. Root area from the apical initial to 6.0 mm distal consisted of 10 to 18% epidermis or exodermis, 67 to 79% cortex, and 10 to 22% vascular cylinder cells containing cambium cells (6 to 20%) and xylem cells (0.8 to 2.5%). These data indicate that N application affects root growth radially by increasing mainly cortex cell area, with less effect on epidermis and central cylinder cells.
Large soft tissue defects around the knee joint are known to significantly diminish joint function. Severe soft tissue defects on the anterior aspect of the knee joint especially bring on significant joint motion limitation. Although simple split skin grafts can cover the skin defect, the progressing scar contracture of the grafted skin causes joint stiffness. One of the best solutions of large soft tissue defects around the knee joint is covering the defect with a good quality skin flap. Separated flaps with one vascular pedicle are good candidates for covering anterior and posterior aspects of the joint for example. Authors performed 12 cases of combined scapular and latissimus dorsi free flaps from 1984 to 2000. Among them, we experienced 5 cases of knee joint defect covering using the double free flap for coverage of the soft tissue defect with preservation of the knee joint function and satisfactory results. The system of flaps based on the subscapular artery and vein provides a variety of composite free flaps. The possible flaps that can be harvested based on this single vascular pedicle include the scapular and parascapular skin flap, the serratus anterior and latissimus dorsi muscular flap, the lateral scapular bone flap, the latissimus dorsi-rib flap, and the serratus anterior-rib flap. This combined flap is available for multiple tissue defects or complex defects because it can be incorporated with skin, muscle and bone flaps. A main advantage is the independent vascular pedicles of each component, which allow freedom in orientation of each components. Consequently it can be freely applied to any form of three dimensional defects on the upper and lower extremities. The combination of scapular cutaneous flap and latissimus dorsi musculocutaneous flap can be resurfaced for massive cutaneous defects on the extremities. We report the use of the combined scapular and latissimus dorsi free flap in five patients to reconstruct massive defects on the extremities with resultant improved joint function. There was no flap failure and minimal complications and disadvantages. The anatomy of this flap is reviewed and the indication and advantages are discussed. All of the five flaps survived and there was no scar contracture affecting the joint motion.

Purpose: In the 1990s, skin island flap supplied by the vascular axis of the sensitive superficial nerves had been introduced. For example, neurocutaneous flaps supplied by the vascular axis of the sural nerve and saphenous nerve have been used. But the flap supplied by the vascular axis of superficial peroneal nerve has not been used commonly. Because there have been few anatomical reports about the superficial peroneal nerve accessory artery(SPNAA), we could not apply the neurocutaneous flap supplied by SPNAA. The aim of this study is to investigate the anatomy of SPNAA, number and location of its perforators, and septocutaneous perforators from the anterior tibial artery in anterior intermuscular septum. Methods: So, we dissected a total of eight cadavers. Measurements were made of the positions of the dissected arteries and perforators from the head of the fibula. Results: In all cadavers the superior lateral peroneal artery was originated from the anterior tibial artery and contributed SPNAA. Arising from the anterior tibial artery an average of 5.63 cm inferior to the fibular head, it varied from 10 cm to 16 cm in length. SPNAA gave off an average of 4.38 perforators to supply lateral aspect. In one case the inferior lateral peroneal artery was present and arose from the anterior tibial artery 18 cm inferior to the fibular head. There were an average of 3.38 direct septocutaneous perforators from the anterior tibial artery. Conclusion: Septocutaneous perforators from SPNAA mainly exist from proximal 1/6 to 3/5 of lower leg. In the distal 1/3 of lower leg where the accessory artery was disappeared, exist mainly direct septocutaneous perforators from the anterior tibial artery. Our results can be helpful to applications of the neurocutaneous flap using SPNAA or fasciocutaneous flap based on direct septocutaneous perforators.

Regulation of vascular smooth muscle cell (VSMC) phenotype plays an essential role in many cardiovascular diseases. In the present study, we provide evidence that $kr{\ddot{u}}ppel$-like factor 8 (KLF8) is essential for tumor necrosis factor ${\alpha}$ ($TNF{\alpha}$)-induced phenotypic conversion of VSMC obtained from thoracic aorta from 4-week-old SD rats. Stimulation of the contractile phenotype of VSMCs with $TNF{\alpha}$ significantly reduced the VSMC marker gene expression and KLF8. The gene expression of KLF8 was blocked by $TNF{\alpha}$ stimulation in an ERK-dependent manner. The promoter region of KLF8 contained putative Sp1, KLF4, and $NF{\kappa}B$ binding sites. Myocardin significantly enhanced the promoter activity of KLF4 and KLF8. The ectopic expression of KLF4 strongly enhanced the promoter activity of KLF8. Moreover, silencing of Akt1 significantly attenuated the promoter activity of KLF8; conversely, the overexpression of Akt1 significantly enhanced the promoter activity of KLF8. The promoter activity of SMA, $SM22{\alpha}$, and KLF8 was significantly elevated in the contractile phenotype of VSMCs. The ectopic expression of KLF8 markedly enhanced the expression of SMA and $SM22{\alpha}$ concomitant with morphological changes. The overexpression of KLF8 stimulated the promoter activity of SMA. Stimulation of VSMCs with $TNF{\alpha}$ enhanced the expression of KLF5, and the promoter activity of KLF5 was markedly suppressed by KLF8 ectopic expression. Finally, the overexpression of KLF5 suppressed the promoter activity of SMA and $SM22{\alpha}$, thereby reduced the contractility in response to the stimulation of angiotensin II. These results suggest that cross-regulation of KLF family of transcription factors plays an essential role in the VSMC phenotype.
The motion features of sanals inside of the primo vascular system (PVS), that is so-called the Kyungrak system, are investigated under a low static magnetic field by using the anatomy technology and optical microscope. The sanals with a size of about 1 selected and separated from the primo vessel and node of the real PVS inside of the surface of the internal organs are observed from rabbits' abdominal wall and dipped with PBS liquid inside of petri dish. The sanal's moving velocity along the direction of magnetic field (xdirection) and perpendicular to the direction of magnetic field (y-direction) under the low magnetic field of 0 Oe, 20 Oe, 40 Oe, 60 Oe, and 80 Oe, respectively, is observed below a internal temperature of $38^{\circ}C$. Ten sanals' moving velocities versus magnetic field are shown two differently dominant tendencies with an average velocity of 0.9 pixel/s and a random velocity according to the x-direction and y-direction, respectively. This experimental results imply that the rotating motion of sanal with nuclei DNA composed of many inorganic magnetic materials of Mn and Co is monotonically weakened by the increase of applied magnetic field.
BACKGOURND/OBJECTIVES: Vascular inflammation is an important feature in the atherosclerotic process. Recent studies report that leaves and branches of Carpinus turczaninowii (C. turczaninowii) have antioxidant capacity and exert anti-inflammatory effects. However, no study has reported the regulatory effect of C. turczaninowii extract on the arterial inflammatory response. This study therefore investigated modulation of the arterial inflammatory response after exposure to C. turczaninowii extract, using human aortic vascular smooth muscle cells (HAoSMCs). MATERIALS/METHODS: Scavenging activity of free radicals, total phenolic content (TPC), cell viability, mRNA expressions, and secreted levels of cytokines were measured in LPS-stimulated (10 ng/mL) HAoSMCs treated with the C. turczaninowii extract. RESULTS: C. turczaninowii extract contains high amounts of TPC ($225.6{\pm}21.0mg$ of gallic acid equivalents/g of the extract), as well as exerts time-and dose-dependent increases in strongly scavenged free radicals (average $14.8{\pm}1.97{\mu}g/mL$$IC_{50}$ at 40 min). Cell viabilities after exposure to the extracts (1 and $10{\mu}g/mL$) were similar to the viability of non-treated cells. Cytokine mRNA expressions were significantly suppressed by the extracts (1 and $10{\mu}g/mL$) at 6 hours (h) after exposure. Interleukin-6 secretion was dose-dependently suppressed 2 h after incubation with the extract, at $1-10{\mu}g/mL$ in non-stimulated cells, and at 5 and $10{\mu}g/mL$ in LPS-stimulated cells. Similar patterns were also observed at 24 h after incubation with the extract (at $1-10{\mu}g/mL$ in non-stimulated cells, and at $10{\mu}g/mL$ in the LPS-stimulated cells). Soluble intracellular vascular adhesion molecules (sICAM-1) secreted from non-stimulated cells and LPS-stimulated cells were similarly suppressed in a dose-dependent manner after 24 h exposure to the extracts, but not after 2 h. In addition, sICAM-1 concentration after 24 h treatment was positively related to IL-6 levels after 2 h and 24 h exposure (r = 0.418, P = 0.003, and r = 0.524, P < 0.001, respectively). CONCLUSIONS: This study demonstrates that C. turczaninowii modulates the arterial inflammatory response, and indicates the potential to be applied as a therapeutic use for atherosclerosis.
Because failure of microvascular flap grafting has sometimes been attributed to vascular obstruction in the anastomotic site, this study investigated the healing process after microvascular anastomoses. The healing process of anastomotic sites were observed by the use of the light and the scanning electron microscope after microvascular anastomoses of the right common carotid artery in rats. The experimental animals were sacrificed on the 4th day, 1st, 2nd, 4th and 6th week. Throughout the whole experimental period, arterial patency rate was 78% (11/14). At the early stage, it was possible to recognize histologically disappearance of endothelial cell and rupture of part of the media. Subintimal hyperplasia and the growth of media appeared around the suture line at the 2nd week. Endothelial cell regeneration occurred and the depth of vessel wall was normalized at the 4th week. By the scanning electron microscope, at the early stage, the anastomotic site was covered with many platelets, red blood cells, fibrins and macrophages. At the 4th week, the insertion site of the thread was completely covered with normal endothelial cells which were parallel to longitudinal axis of vessels and complete reendothelialization over the anastomotic site seemed to take about 6th week.

Enzymatic oxidation of commercially available pyrogallol was efficiently transformed to an oxidative product, purpurogallin. Purpurogallin plays an important role in inhibiting glutathione S-transferase, xanthine oxidase, catechol O-methyltransferase activities and is effective in the cell protection of several cell types. However, the anti-inflammatory functions of purpurogallin are not well studied. Here, we determined the effects of purpurogallin on lipopolysaccharide (LPS)-mediated proinflammatory responses. The results showed that purpurogallin inhibited LPS-mediated barrier hyper-permeability, monocyte adhesion and migration and such inhibitory effects were significantly correlated with the inhibitory functions of purpurogallin on LPS-mediated cell adhesion molecules (vascular cell adhesion molecules, intracellular cell adhesion molecule, E-selectin). Furthermore, LPS-mediated nuclear factor-${\kappa}B$ (NF-${\kappa}B$) and tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$) releases from HUVECs were inhibited by purpurogallin. Given these results, purpurogallin showed its anti-inflammatory activities and could be a candidate as a therapeutic agent for various systemic inflammatory diseases.

The functional deformity following removal of the maxilla is considerable, especially following maxilla cancer excision. Rehabilitation of oral and maxillofacial region used to be very difficult with prosthesis or traditional flaps. Temporal muscle and fascia flaps have been described for immediate reconstruction following hemi-maxillectomy, but not total maxillectomy. The muscle and superficial fascia of the temporal area differ in their physical characteristics, vascular supply and clinical applications. Both can be employed independently or simultaneously as regional flaps in the reconstruction of a variety of complex craniofacial defects. Four case is presented in which 3 case maxilla cancer, one case non-union after maxilla fracture, and all case showed successful use of this flap. Only one patient developed partial necrosis of the flap ; significant necrosis did not occur in any other patient. This present paper reviews the anatomy, surgical technique and utilisation of temporal muscle and fascia flaps.
