Objective: Hemocoagulase agkistrodon (HCA), a thrombin-like enzyme (TLE) from the venom of the Chinese moccasin snake ( Deinagkistrodon acutus ), has been used in clinical practice as a hemostatic compound. The aim of this study was to further investigate the pharmacological properties of HCA. Materials and methods: Sodium dodecyl sulfate or native polyacrylamide gel electrophoresis (SDS- or N-PAGE) as well as enzyme linked immunosorbent assays (ELISAs) were conducted to study the effects of HCA on the human plasma fibrinogen and prothrombin levels, as well as its in vitro interactions with some coagulation factors...

Hemocoagulase Agkistrodon Halys Pallas, a well-established hemostatic agent used in China, has widespread applications in various conditions of bleeding and hemorrhages. Although it presents a low risk of vascular thrombosis, the agent can be easily tolerated and does not show any harmful effects, except allergy. However, long-term use of hemocoagulase may induce hypofibrinogenemia in some patients. Herein, we report 11 patients of prolonged administration of hemocoagulase Agkistrodon, with particular attention to the dynamic changes in their coagulation functions...

Hemocoagulase has been successfully used for the management of bleeding in patients undergoing surgery. Local spray of hemocoagulase during endoscopic therapy may be effective for the management of gastrointestinal bleeding. In China, intravenous infusion of hemocoagulase is given by some physicians for the treatment of gastrointestinal bleeding. However, the potential adverse events secondary to hemocoagulase, such as hypofibrinogenemia, are poorly recognized. In this paper, we reported an elderly patient with type II respiratory failure in whom hemocoagulase might induce hypofibrinogenemia and further worsen gastrointestinal bleeding...

RATIONALE: Ticagrelor has become one of the first-line antiplatelet agents in acute coronary syndrome (ACS) patients recommend by the guideline due to its more potent and predictable antiplatelet effect. However, bleeding is still a severe drug adverse reaction of ticagrelor therapy. We report a first case on ticagrelor-induced life-threatening bleeding via the cyclosporine-mediated drug interaction. PATIENT CONCERNS: A 58-year-old Chinese male who received cyclosporine 200 mg daily 5 years after renal transplantation...

We investigated a new method for combining microbubble-enhanced ultrasound cavitation (MEUC) with hemocoagulase (HC) atrox. Our goal was to induce embolic effects in the vasculature and combine these with an anti-angiogenic treatment strategy. Fourteen days after being implanted with a single slice of the liver VX2 tumor, rabbits were randomly divided into five groups: (i) a control group injected intra-venously with saline using a micropump; (ii) a group given only an injection of HC; (iii) a group treated only with ultrasound cavitation; (iv) a group treated with MEUC; (v) a group treated with MEUC + HC...

OBJECTIVE: To observe the effect of endotracheal tube with subglottic suction line on tracheostomy bleeding in critical patients. METHODS: This procedure was utilized for 35 critical patients with tracheostomy bleeding. With the help of bronchoscope, the endotracheal tube with subglottic suction line was inserted during tracheostomy to 0.5-1.0 cm above the carina. Then aerocyst of the tube was inflated, vacuum was set up for continuous suction via suction port, and hemocoagulase was injected to the opening of tracheostomy...

Objective To evaluate the hemostatic effect of hemocoagulase agkistrodon on surgical wound in breast cancer surgery. Methods Totally 60 patients undergoing breast cancer surgery were enrolled in this prospective,randomized,double-blinded,and controlled study. All the patients met the inclusion and exclusion criteria and signed the informed consent. Hemocoagulase agkistrodon (2 U) was injected 20 minutes before surgery and 4 and 24 hours after surgery in the intervention group (n=30),whereas normal saline was used instead in the control group (n=30)...

BACKGROUND In patients with large colon polyps, late-onset bleeding may be more likely to occur because of the larger cutting surface. In these patients, hemostatic agents may be applied to prevent the late-onset bleeding. A total of 7 patients developed hypofibrinogenemia caused by hemocoagulase following excision of colon polyps in our center from November to December 2015. CASE REPORT Seven patients underwent excision of colon polyps in our center from November to December 2015. The cutting face was large in these patients after surgery; therefore, hemocoagulase was used to prevent potential late-onset bleeding...

BACKGROUND: Uncontrolled bleeding is associated with poor outcomes and mortality in geriatric patients undergoing hemiarthroplasty. Hemocoagulase agkistrodon is a hemocoagulative, anti-hemorrhagic enzyme complex from Deinagkistrodon acutus snake venom. This study aimed to investigate the efficacy of hemocoagulase agkistrodon on coagulation and bleeding outcomes in fracture-related hemiarthroplasty. PATIENTS AND METHODS: This was a prospective, single-blinded, randomized controlled trial carried out between October 2013 and September 2014 in 96 geriatric patients undergoing hemiarthroplasty for unilateral femoral neck fracture...

Aiming at the shortage of the Raman spectra of drugs and the current situation of drug testing, we have applied Raman spectroscopic technique to several kinds of medicine, such as antibiotics, antihistamine, hemocoagulase and antiemetics. The spectral properties for the samples with high Raman activity are investigated by observing their Raman spectra to yield the shift, intensity, and line width of the Raman peaks, as well as the line shape of Raman envelope. For those samples with weak Raman activity or complex structures that are hard to be identified, we have also made some tentative measurements or raise some suggestions for future measurement...

A 61 year-old male patient, plasma fibrinogen level was 2.98 g/L, endoscopic sinus surgery was performed under general anesthesia for polypoid of uncinate process with mycotic maxillary sinusitis. Hemocoagulase were given in pre- and post-operative for treatment. The patient was found postoperative drain blood continuously since 3 days after surgery, when the dose of hemocoagulase reach 26 KU, and fibrinogen determined in Plasma was 0.48 g/L. Coagulation returned to normal and nasal bleeding stopped after discontinuation of the hemocoagulase and supplement with fibrinogen...

Higher levels of fibrinogen, a critical element in hemostasis, are associated with increased postoperative survival rates, especially for patients with massive operative blood loss. Fibrinogen deficiency after surgical management of intracranial tumors may result in postoperative intracranial bleeding and severely worsen patient outcomes. However, no previous studies have systematically identified factors associated with postoperative fibrinogen deficiency. In this study, we retrospectively analyzed data from patients who underwent surgical removal of intracranial tumors in Beijing Tiantan Hospital date from 1/1/2013to12/31/2013...

Hemocoagulase agkistrodon for injection is the national first-class new drug of China with good hemostatic function and safety for capillary hemorrhage in abdominal incision of surgical patients. Adverse drug reactions (ADRs) to hemocoagulase agkistrodon are rarely reported. In this paper, we describe a case of a 41-year-old woman who developed anaphylactic shock attributed to hemocoagulase agkistrodon before colon cancer surgery. Based on the Naranjo ADR probability score, a "probable" cause and effect relationship existed for this case...

OBJECTIVES: To evaluate the effects of topical hemocoagulase on intra-oral extraction sockets and impact on the healing process as well as to produce a clinico-histological healing score. STUDY DESIGN: This prospective study compared two extraction sites in each subject. One site received topical hemocoagulase while other site did not receive it. Both the sites were chosen in the same patient and extraction was done at separate intervals. The biopsy was done on a random basis with the pathologist being blinded to the study...
