  • Thrombophilia refers to inherited or acquired hemostatic disorders that result in a predisposition to blood clot formation. When combined with the hypercoagulable state that is characteristic of pregnancy, there is an increased risk of severe and recurrent pregnancy complications. Activated protein C resistance caused by factor V Leiden (FVL) mutation is known to be the most common cause of inherited thrombophilia in Caucasian population. FVL mutation has been related to pregnancy complications associated with hypercoagulation, e.g. miscarriage, intrauterine fetal demise, placental abruption, and intrauterine growth retardation. Although the FVL mutation is easily detected using molecular DNA techniques, patients who are heterozygous for this disorder often remain asymptomatic until they develop a concurrent prothrombotic condition. Because there are potentially serious effects of FVL mutation for pregnancy, and because effective treatment strategies exist, early detection and treatment of this condition might be considered.

  • The common local causes of active gingival bleeding are the vessel engorgement and erosion by severe inflammation and injury to hypervascularity lesion. Abnormal gingival bleeding is also associated with systemic bleeding disorders (liver disease, leukemia etc.). There are many conventional methods for gingival bleeding control, such as, direct pressure, packing, electrocoagulation, tight suture and application of hemostatic agents. If the continuous gingival bleeding is not stopped in spite of the all local application methods, the medical consultation should be obtained for systemic condition care and the major feeding arterial embolization. This is a case report of severe gingival bleeding and periodontitis control in a patient with liver cirrhosis and oral metastatic lesion of hepatocellular carcinoma. The bleeding lesion was placed in left buccal mucosa and gingiva of the left mandibular molars. The control methods were dental crown removal, primary endodontic drainage, gingival sulcus drainage and maxillary arterial embolization with medical consultation.

  • Objectives: The purpose of this study is to analyze the domestic study trends of pharmacopuncture therapy on obstetrics and gynecological diseases in Korean literature, through reviewing the clinical and experimental studies. Methods: We searched for clinical and experimental studies using pharmacopuncture therapy on obstetrics and gynecological diseases, published from January 2000 to May 2019, through 5 Korean databases. The study design, target disease, type of pharmacopuncture, method of intervention, and study results were analyzed. Results: 36 experimental studies and 15 clinical studies were finally included according to inclusion and exclusion criteria. In experimental studies, there were 12 studies about postmenopausal osteoporosis, 9 studies about obesity, 4 studies about endometriosis, 3 studies about hemostatic effects and analgesic anticoagulative effects, 2 studies about ovarian function, and analgesic antiphlogistic anticoagulative effects, and 1 study about menopausal symptoms. In clinical studies, there were 3 studies about obesity, postpartum disorders, dysmenorrhea, and women's urologic disease, and 1 study about menopausal symptoms, atypical squamous cells of undetermined significance (ASCUS) and breast cancer. Various types of pharmacopuncture have been proved to have a therapeutic effect in each of those obstetrics and gynecological diseases. Conclusions: This study indicates that pharmacopuncture therapy could be a good treatment for obstetrics and gynecological diseases. However, more well-designed and high-quality clinical researches are needed in further studies, to prove the effectiveness and safety of pharmacopuncture therapy.

  • Wound care is a health industry concern affecting millions worldwide. Recent increase in metabolic disorders such as diabetes comes with elevated risk of wound-based complications. Treatment and management of wounds are difficult practices due to complexity of the wound healing process. Conventional wound dressings and treatment applications only provide limited benefits which are mainly aimed to keep wound protected from external factors. To improve wound care, recent developments make biopolymers to be of high interest and importance to researchers and medical practitioners. Biopolymers are polymers or natural origin produced by living organisms. They are credited to be highly biocompatible and biodegradable. Currently, studies reported biopolymers to exhibit various health beneficial properties such as antimicrobial, anti-inflammatory, hemostatic, cell proliferative and angiogenic activities which are crucial for effective wound management. Several biopolymers, namely chitosan, cellulose, collagen, hyaluronic acid and alginic acid have been already investigated and applied as wound dressing agents. Different derivatives of biopolymers have also been developed by cross-linking with other molecules, grafting with other polymers, and loading with bioactive agents or drugs which showed promising results towards wound healing without any undesired outcome such as scarring and physiological abnormalities. In this review, current applications of common biopolymers in wound treatment industry are highlighted to be a guide for further applications and studies.

  • Platelet aggregation is essential for the formation of a hemostatic plug in the case of blood vessel damage. On the other hand, excessive platelet aggregation may cause cardiovascular disorders, such as thrombosis, atherosclerosis, and myocardial infarction. Scopoletin, which found in the root of plants in the genus Scopolia or Artemisia, has anti-coagulation and anti-malaria effects. This study examined the effects of scopoletin on human platelet aggregation induced by collagen. Scopoletin had anti-platelet effects via the down-regulation of thromboxane $A_2$ ($TXA_2$) production and intracellular $Ca^{2+}$ mobilization ($[Ca^{2+}]_i$), which are aggregation-inducing molecules produced in activated platelets. On the other hand, scopoletin increased both the cyclic adenosine monophosphate (cAMP) and cyclic guanosine monophosphate (cGMP) levels, which are known as intracellular $Ca^{2+}$-antagonists and aggregation-inhibiting molecules. In particular, scopoletin increased the potently cAMP level more than cGMP, which led to suppressed fibrinogen binding to ${\alpha}IIb/{\beta}_3$ in collagen-induced human platelet aggregation. In addition, scopoletin inhibited collagen-elevated adenosine triphosphate (ATP) release in a dose-dependent manner. The results suggest that aggregation amplification through granule secretion is inhibited by scopoletin. Therefore, scopoletin has potent anti-platelet effects and may have potential for the prevention of platelet-derived vascular diseases.
