Oral prostaglandin E1 (PGE1) is a medicine that is clinically applied during a treatment of patients suffering with vascular disease with chronic arterial obstruction because it has vasodilation and anti-platelet effects. The mechanisms of lumbosacral symptoms associated with spinal stenosis probably include vascular insufficiency with hypoxic injury to the cauda equina and the nerve roots. Thus, increasing the blood supply would be beneficial to improve the pathophysiologic condition. Several studies on the improvement of clinical symptoms of spinal stenosis by PGE1 treatment have been reported on. In this case, 47-year old female underwent posterior compression and posterolateral fusion with a cage at L2-4 due to L3 compression fracture, and she did not show improvement of the radiating pain of her right leg after the operation. Therefore, she received repetitive epidural catheterization and adhesiolysis, epidural block and physical therapy, but her symptoms deteriorated after temporary improvement. Finally, she was given PGE1 and the radiculopathy was completely improved, although some muscle weakness still remained.

The mechanism by which blastocysts implant to uterine endometrium has not been clearly understood. In the present study, the following question was investigated: how are hormonal levels changed and how is uterine endometrium morphologically changed? Results obtained are as follows: Concentrations of serum estradiol and progesterone were significantly increased on day 4 and 5 of pregnancy. Uterine concentrations of PGE and $PGE_{2a}$ were sharply increased on day 1 and maintained similar concentrations thereafter, reaching the maximum on day 5. Both prostaglandins (PGs) concentrations were gradually decreased thereafter. Furthermore, concentrations of PGs in implant sites were greater than those in non-implant sites. PBR (pontamine blue reaction) in uterine endometrium was positive on day 6 of pregnancy, indicating that vascular permeability was increased. Edema and changes in structure of cell components were pronounced in stroma where PBR was developed. Moreover, these were more prominent in implant sites than non-implant sites. These results suggest that uterine PGs as well as steroid hormones increase during implantation in rats and these hormones might be involved in the process of implantation by modulating vascular permeability and the fine structures of uterine endometrial cells.

Aneurysmal bone cyst (ABC) is benign vascular lesion destructing the cortical bone by the expansion of the vascular channel in the diploic space that usually involve long bone and spine. Orbital ABC is rare and the clinical symptoms deteriorate rapidly after initial slow-progression period for a few months. A 12-year-old female patient visited ophthalmologist due to proptosis and upward gaze limitation of the right eye, and orbital mass was noted in the upper part of right eye on orbital MRI. Five months later, exophthalmos was worsened rapidly with other features of ophthalmoplegia. Orbital mass was enlarged on MRI with intracranial extension. Surgery was done through frontal craniotomy and intracranial portion of the tumor was removed. Destructed orbital roof and mass in the orbit was also removed, and surrounding bone which was suspected to have lesion was resected as much as possible. Histopathological diagnosis was aneurysmal bone cyst. Postoperative course was satisfactory and the patient's eye symptoms improved. Authors report a rare case of orbital ABC with review of the literature. Exact diagnosis by imaging studies is important and it is recommended to perform surgical resection before rapid-progressing period and to resect the mass completely to prevent recurrence.

Metabolic disease such as diabetes, which is caused by stress or imbalanced diet, has been increasing. A diabetic tend to suffer from a delay or difficulty of wound healing. The extract of SHIKON (SK), that is the root of Lithospermun erythrorhison, has been reported to have an effect on healing for normal wound, but has never studies for intractable wound so far. Therefore we examined the effect of SK extract on wound healing with healing impaired mouse model. Full-thickness round wounds were created on the backs of db/db mice and applied SK, and we observed neovascularization and collagen synthesis, distribution of apoptotic cells, and vascular endothelial growth factor (VEGF)- positive cells in granulation tissue. After two weeks, a number of capillary vessel and collagen synthesis were increased in SK-treated wounds. Infiltration of VEGF-positive neutrophils was also seen in the wound, besides apoptotic fibroblasts and endothelial cells were appeared in the granulation tissue. After three weeks, the wound closed completely with SK-treated but not in control. These results suggest that SK enhanced neovascularization by VEGF and this kind of apoptosis process makes the scar smooth. In this study, it is obvious that SK also accelerates healing of intractable wound.

Angiogenesis, the formation of blood vessels, is essential for preparing a closed circulatory system in the body, and for supplying oxygen and nutrition to tissues. Major diseases such as cancer, rheumatoid arthritis, and atherosclerosis include pathological angiogenesis in their malignant processes, suggesting anti-angiogenic therapy to be a new strategy for suppression of diseases. However, until the 1970s, the molecular basis of angiogenesis was largely unknown. In recent decades, extensive studies have revealed a variety of angiogenic factors and their receptors, including vascular endothelial growth factor (VEGF)-VEGFRs, Angiopoietin-Tie, Ephrin-EphRs and Delta-Notch to be the major regulators of angiogenesis in vertebrates. VEGF and its receptors play a central role in physiological as well as pathological angiogenesis, and functional inhibitors of VEGF and VEGFRs such as anti-VEGF neutralizing antibody and small molecules that block the tyrosine kinase activity of VEGFRs have recently been approved for use to treat patients with colorectal, lung, renal and liver cancers. These drugs have opened a novel field of cancer therapy, i.e. anti-angiogenesis therapy. However, as yet they cannot completely cure patients, and cancer cells could become resistant to these drugs. Thus, it is important to understand further the molecular mechanisms underlying not only VEGF-VEGFR signaling but also the VEGF-independent regulation of angiogenesis, and to learn how to improve anti-angiogenesis therapy.

Objectives : The aim of this systemic review was to summarize and compare adverse effect of spinal manipulation at domestic and abroad. Methods : We searched articles in Korean databases and Pubmed. We selected and analysed the articles met inclusion criteria. Results : 51 cases were included. 32 cases in Pubmed show that adverse effect related to cervical rotation and high velocity low amplitude(HVLA) thrust manipulation. It leads to severe adverse effect and sequela about vascular. While, 19 cases in Korean articles shows that domestic spinal manipulation is more safe becase of lower use of high velocity low amplitude(HVLA) thrust. It leads to low incidence of vascular adverse effect and no sequela. Conclusions : We concluded that Chuna is difficult manipulation because of possibility of adverse effect. Chuna is recommended to be taken by licensed medical practitioners who are skilled and complete the regular curriculum. Further studies like meta analysis about spinal manipulation are needed to estimate incidence of adverse effect. And adverse effects are going to be collected continually through randomized controlled trials(RCT) related to spinal manipulation.

There are many things in common between hemodynamics in arterial systems and multibody dynamics in mechanical systems. Hemodynamics is concerned with the forces generated by the heart and the resulting motion of blood through the multi-branched vascular system. The conventional hemodynamics model has been intended to show the general behavior of the body arterial system with the frequency domain based linear model. The need for detailed models to analyze the local part like coronary arterial tree and cerebral arterial tree has been required recently. Non-linear analysis techniques are well-developed in multibody dynamics. In this paper, the studies of hemodynamics are summarized from the view of multibody dynamics. Computational algorithms of arterial tree analysis is derived, and proved by experiments on animals. The flow and pressure of each branch are calculated from the measured flow data at the ascending aorta. The simulated results of the carotid artery and the iliac artery show in good accordance with the measured results.
