  • This study is intended to investigate the fundamental properties of concrete which AE water reducing agent for reduction of bleeding is used, and the properties of bleeding reduction. According to the results, when the adding ratio of AE water reducing agent for reduction of bleeding increases, a range of normal fluidity and aimed air content arc satisfied, setting time is faster than that of normal AE water reducing agent. And bleeding amount decreases, bleeding speed is highest between 60 and 90 min, and sinking depth increases drastically in 60 min. When, AE water reducing agent for reduction of bleeding is added, compressive strength shows a slight variation by air content, but there is not a large influence by addition of AE water reducing agent for reduction of bleeding. Synthetically, it proves that AE water reducing agent for reduction of bleeding satisfies aimed air content in the range of normal slump and can reduce only bleeding without quality variation of compressive strength.

  • This study is intended to investigate the properties of bleeding reduction of concrete using AE water reducing agent for the type of bleeding reduction with the replacement admixture. According to the results, when the adding ratio of AE water reducing agent for the type of bleeding reduction increases, a range of normal fluidity and aimed air content are satisfied, setting time is faster than that of normal AE water reducing agent. And bleeding amount decreases, bleeding speed is highest between 60 and 90 min, and sinking depth increases drastically in 50 min. When AE oater reducing agent for the type of bleeding reduction is added, compressive strength shows a slight variation by air content, but there is not a large influence by addition of AE water reducing agent for the type of bleeding reduction. Synthetically, it proves that AE water reducing agent for the type of bleeding reduction satisfies aimed air content in the range of normal slump and can reduce only bleeding without quality variation of compressive strength.

  • Excessive oral and maxillofacial bleeding causes upper airway obstruction, bronchotracheal & gastric aspiration and hypovolemic shock. Therefore, the rapid & correct bleeding control is very important for life-saving in the medical emergency room. In spite of the bleeding control methods of the wound suture & direct pressure, the postoperative bleeding can be occurred, because of the presence of various bleeding disorders & postoperative delayed wound infections. The proper care of bleeding disorders & wound infections are very important for the control of the delayed postoperative rebleeding. In spite of these methods, active oral bleeding can be presented by the other causes of head injury. A rare but particularly dangerous sort of bleeding that may have an especial importance to the patient with severe basal skull fracture that damage large vessels and even the cavernous sinus. The occurrence of profuse nasal or oropharyngeal bleeding may arise from damage to the anterior and posterior ethmoidal vessels, but when mixed with brain tissue it is evidence of mortal damage. In this condition, rapid entire oropharyngeal packing is essential for the control of active oral bleeding. This is a case report of rapid rational bleeding control method by much amount of wet gauze packings, in a 44-years-old male patient with active oropharyngeal bleeding by basal skull fractures.

  • This paper describes the properties analysis of concrete using bleeding reduction agent. According to the results, the fluidity and the air content of fresh concrete with increase of bleeding reduction agent show little difference in compare with plain concrete which does not use bleeding reduction agent. The efficiency of bleeding reduction agent is confirmed because in variation of W/C and slump, the increase of bleeding reduction agent dosage reduces bleeding remarkably. And the compressive strength of hardened concrete does not show any differences with increase the dosage of bleeding reduction agent. Bleeding reduction agent does not have bad effect on the quality of concrete such as fluidity, air content and the strength of hardened concrete and so on, the dosage of it can reduce bleeding effectively.

  • Objectives: This paper aim to report the effects of korean medical treatment including Yikwiseungyang-tang-gagambang on patients with abnormal uterine bleeding. Methods: From 2012 August to 2017 June, six outpatient with abnormal uterine bleeding came to the clinic. The patients took Yikwiseungyang-tang-gagambang and got acupuncture and warm needle therapy. We assessed the patients' bleeding period and bleeding amount. Results: All patients' abnormal uterine bleeding stopped after they took Yikwiseungyang-tang-gagambang in 2~40 days. One patient restart slight bleeding, the bleeding stopped after continual korean medical treatment. Conclusions: Korean medical treatment including Yikwiseungyang-tang-gagambang is effective on patients with abnormal uterine bleeding.

  • Gastrointestinal bleeding is a common cause of hospitalization. Jejunal diverticula is a rare disease and it is an unusual cause of obscure gastrointestinal bleeding. After exclusion of the more common bleeding sources, small bowel diverticula should be considered as a possible rare cause of gastrointestinal bleeding. Jejunal diverticular bleeding is difficult to diagnose and treat because the bleeding site cannot be identified by routine endoscopy and radiologic studies. An exploratory operation is sometimes needed to diagnose and treat obscure gastrointestinal bleeding. If the bleeding site is certain, then surgical resection of the bleeding part of the bowel is the procedure of choice. We report here on a case of jejunal diverticular bleeding that was diagnosed by and treated with surgical resection.

  • The general local cause of gingival bleeding is the vessel engorgement and erosion by odontogenic infection. Abnormal gingival bleeding is also associated with systemic causes. Bleeding disorders in which continuous gingival bleeding is encountered include the followings : vascular abnormalities, platelet disorders, hypoprothrombinemia and other coagulation defects. There are classic methods for gingival bleeding control, such as, direct pressure, electrocoagulation, suture, crushing and application of hemostatic agents. If the continuous gingival bleeding is not stopped in spite of the conventional methods, the life of patient is threatened owing to upper airway obstruction, syncope, vomiting and hypovolemic shock. Therefore, the rapid and correct hemostatic method is very important in the emergency condition. This is a case report of continuous gingival bleeding control by primary endodontic drainage & suture in a disabled patient with systemic bleeding disorders.

  • While oral and maxillofacial surgery such as orthognathic surgery, TMJ surgery is in progress, there always exists a risk of bleeding from maxillary artery, and this perplexes the surgeon in operation. In case of massive bleeding, it is mostly very difficult or even impossible to take an immediate action in order to stop bleeding. Even when hemostasis is possible by applying such methods as the use of local hemostatics, pressing, electrocoagulation or direct ligation, there is a high risk of secondary bleeding. Therefore, in case there is bleeding from maxillary artery, it is the best to restrain bleeding completely either by the ligation of the artery in bleeding in operation fields or by the ligation of the external carotid artery.

  • The purpose of this study is to report the hemostatic effects of Kungkwikyoae-tang for abnormal uterine bleeding. Kungkwikyoae-tang has been known as a useful herbal medication for uterine bleeding. We treated patients who had been suffering from abnormal uterine bleeding with herb-medication, acupuncture therapy, pharmacopuncture therapy and moxa therapy. We prescribed Kungkwikyoae-tang three times a day. The improvement of symptoms were measured by checking patient bleeding volume, frequency and other physical signs. After Kungkwikyoae-tang was given, abnormal uterine bleeding volume and frequency was reduced and other physical symptoms were improved. This case study shows that Kungkwikyoae-tang has a hemostatic effects against the abnormal uterine bleeding.
