  • The purpose of the present study was to examine the efficacy and mechanism of the fraction IV cold ethanol fractionation and pasteurization ($60^{\circ}C$ heat treatment for 10h) steps, involved in the manufacture of albumin from human plasma, in the removal and/or inactivation of blood-born viruses. A variety of experimental model viruses for human pathogenic viruses, including the Bovine viral diarrhoea virus (BVDV), Bovine herpes virus (BHV), Murine encephalomyocarditis virus (EMCV), and Porcine parvovirus (PPV), were selected for this study. Samples from the relevant stages of the production process were spiked with the viruses, and the amount of virus in each fraction was then quantified using a 50% tissue culture infectious dose ($TCID_{50}$). The mechanism of reduction for the enveloped viruses (BHV and BVDV) during fraction IV fractionation was inactivation rather than partitioning, however, it was partitioning in the case of the non-enveloped viruses (EMCV and PPV). The log reduction factors achieved during fraction IV fractionation were ${\geq}6.9$ BHV, $\geq5.2$ for BBDV, 4.9 for EMC, and 4.0 for PPV. Pasteurization was found to be a robust and effective step in inactivating the enveloped viruses as well as EMCV. The log reduction factors achieved during pasteurization were $\geq7.0$ for BHV, $\geq6.1$ for BVDV, $\geq6.3$ for EMCV, and 1.7 for PPV. These results indicate that the production process for albumin has sufficient virus-reducing capacity to achieve a high margin for virus safety.

  • Temporomandibular joint(TMJ) ankylosis is characterized by the formation of bony or fibrous mass, which replaces the normal articulation. Ankylotic block formation causes reduction of mandibular mobility, particularly hindering mouth opening, due to a mechanical block of the condylar head in its roto-transfatory motion. Surgery in TMJ ankylosis treatment entails complete ankylotic block removal and subsequent arthroplasty, possibly with autologous tissue between articular surfaces or heterologous material to restore the anatomic structure and normal function. Temporalis myofascial flap holds great promise for the reconstruction of various maxillofacial defects. In more recent years, a pedicled temporalis myofascial flap has been advocated in TMJ ankylosis surgery. Advantages of the temporalis myofascial flap in TMJ reconstruction include close proximity to the TMJ, adequate blood supply from the internal maxillary artery, and its attachment to the coronoid process, which provides movement of the flap during function, simulating physiologic action of the disc. This study evaluated 8 patients(11 TMJs) affected by TMJ ankylosis. All patients underwent surgical treatment of the removal of the ankylotic block and subsequent interpositional arthroplasty with temporalis myofascial flap. Bilateral TMJ ankylosis was observed in 3 patients(6 TMJs), right-sides in 3 patients, left-sided in 2 patients. Epipathogenesis was traumatic in 6 patients(8 TMJs), ankylosing spondylitis in 2 patients(3 TMJs). In 3 patients coronoidotomy was underwent. Average follow-up was 16.8 months after surgery, with a range of 7 to 28 months. No patients underwent additional TMJ procedures after the temporalis myofascial flap. All patients showed a distinctive improvement both in articular functionality and symptoms. We found that temporalis myofascial flap is very valuable in reconstruction of TMJ ankylosis.

  • Chronic osteomyelitis is an infection and inflammation of the bone or bone marrow, causing ischemia in bone marrow due to lack of blood, nutrients, and oxygen supply to the bone marrow, eventually leading to necrosis of bone marrow. A current method for treatment of chronic osteomyelitis is administration of systemic antibiotics followed by removal of the infected bone and tissues. Because infected tissue of chronic osteomyelitis is surrounded by avascular necrotic bone, supply of blood and antibiotics to the infected area is diminished. For effective treatment, high plasma concentrations of antibiotics should be provided for a prolonged period. However, long term high serum level of antibiotics may result in undesirable adverse effects. For delivery of a sufficient concentration of antibiotic to the infected area while avoiding the adverse effect, implantation of a local antibiotic delivery system is suggested. One of the implantation systems that has been utilized is antibiotic impregnated polymethyl methacrylate.

  • The four principles of treatment of odontogenic infection are as follows : (1) removal of the cause, (2) establishment of drainage, (3) institution of antibiotic therapy, and (4) provision of supportive care, including proper rest and nutrition. A separate incision is required to establish drainage, especially in the case of extensive fascial space infections. There are four principle causes for active bleeding in the immediate incision & drainage phase; (1) vascular wall alteration (infection, scurvy, chemicals), (2) disorder of platelet function, (3) thrombocytopenic purpuras, (4) disorders of coagulation (liver disease, anticoagulation drug). If the hemorrhage from incision & drainage site is aggressive, the site must be packed with proper wet gauze and wound closure & drainage dressing are applied. The specific causes of bleeding may be associated with hypoxia, changes in the pH of blood & chemical changes affecting vascular contractility and blood clotting. This is a case report of bleeding control by the circumferential suture & drainage on active bleeding incision & drainage site of temporal space abscess due to advanced odontogenic infection in a multiple medically compromised disabled patient.

  • Viral, bacterial and fungal infections can be transmitted via allografts such as bone, skin, cornea and cardiovascular tissues. Allogenic bone grafts have possibility of transmission of hepatitis C, human immunodeficiency virus (HIV-1), human T-Cell leukaemia virus (HTLV), tuberculosis and other bacterias. The tissue bank should have a policy for obtaining information from the patient's medical report as to whether the donor had risk factors for infectious diseases. Over the past several years, improvements in donor screening criteria, such as excluding potential donor with "high risk" for HIV-1 and hepatitis infection, and donor blood testing result in the reduction of transmission of these diseases. During tissue processing, many allografts are exposed to antibiotics, disinfectants and terminal sterilization such as irradiation, which further reduce or remove the risk of transmitting diseases. Because the effectiveness of some tissue grafts such as, fresh frozen osteochondral grafts, depends on cellular viability, not all can be subjected to sterilization and processing steps and, therefore, the risk of transmission of infectious disease remains. This article is review of the transmission of considering infectious disease in allogenic bone transplantation and the processing steps of reducing the risk. The risk of viral transmission in allografts can be reduced in several standards. The most important are donor-screening tests and the removal of blood and soft tissues by processing steps under the aseptic environment. In conclusion, final sterilizations including the irradiation, can be establish the safety of allografts.

  • This study is a clinical report of one patient with symptoms remaining after western medical therapy for ulcerative colitis. Ulcerative colitis, a diffuse inflammatory disease of the mucosal lining of the colon and rectum, is characterized by a remitting and relapsing course. Therefore treatment is difficult and the proper treatment typically isn't established. We provided acupuncture-moxibustion therapy 28 times and prescribed Dansamboheol-tang gagam, which functions by nourishing the blood (補血), strengthening the spleen (健脾), adjustment of ki (理氣), removal of extravasated blood (祛瘀), and warming of the kidney (溫腎), for 30 days. The patient improved in quality of life and the symptoms disappeared. This study suggests that Dansamboheol-tang gagam, acupuncture, and moxibustion treatment has an effect on improving the symptoms remaining after western medical therapy for ulcerative colitis.

  • The glucose tolerance and pancreatic insulin secretion response to glucose in sheep fed on germinated sorghum grain were determined using an intravenous glucose load. Twelve male Thin Tail sheep (an Indonesian native sheep, 12 months old and 14.8 kg average body weight) were divided randomly into sorghum grain-based (S), germinated sorghum grain-based (G) and maize grain-based (C) diets. Sheep were maintained at the same daily intake levels of metabolizable energy and crude protein in the diets throughout the experimental period. After two months of the experimental conditions, each diet group was subjected to an intravenous glucose load experiment in which five doses of glucose (0, 10, 20, 40 and 80 mg/kg BW) were injected to estimate the rate of glucose removal from blood and the pancreatic insulin secretion response. For each sheep and each glucose load dose, the incremental blood serum glucose and insulin concentrations above pre-injection concentration were calculated as serum glucose and insulin response areas. At all glucose doses, sheep fed on S diet had a greater (p<0.05) glucose response area compared to those of sheep fed on G and C diets. Likewise at all glucose doses, the insulin response area was smaller (p<0.05) in sheep fed on S diet than in sheep fed on G and C diets. The glucose and insulin response areas in sheep fed on G and C diets differed slightly. It was concluded that the portion of maize grain in the ruminant ration could be substituted by germinated sorghum grain.

  • Intracranial hemorrhage due to preeclampsia in the postpartum woman is rarely documented. Generally, the incidence of stroke is increased during pregnancy and early postpartum. Preeclampsia is considered a main cause of both nonhemorrhagic and hemorrhagic stroke. We present a 32-year-old woman who had intracranial hemorrhage at 5 days postpartum. At admission, her consciousness was semicomatose with elevated blood pressure. Computerized tomography revealed intracranial hemorrhage on right frontal lobe. Additional angiography did not reveal abnormal vascular lesion. Emergency craniectomy with hematoma removal was done. However, the patient showed no recovery and died 2 weeks later. We conclude that postpartum care of preeclampsia is important to prevent intraparenchymal hemorrhage. Relative high risk of stroke during the postpartum period suggests a causal roles for the large decrease in blood volume or the rapid changes in hormonal status that follow a live birth or stillbirth, perhaps by means of hemodynamics, coagulative, or vessel wall changes.

  • We here document discovery of expression profile of myeloid derived suppressor cells (MDSCs) in chronic hepatitis B (CHB) patients and changes in the course of disease. The study population was composed of 75 outpatient HBV cases and 15 healthy control cases. Peripheral blood samples were collected for separation of mononuclear cells. Levels of MDSCs labeled with Lin-DR-CD11b+CD33+ obtained from peripheral blood mononuclear cells (PBMC), were revealed to have significant differences between the CHB and other groups. They were 0.414% for health control cases and 0.226% for CHB cases (Z=-2.356, p=0.0189). It also observed that the group of HBeAg positive cases had significant difference in MDSCs/PBMC median ($X^2=11.877$, p=0.003), compared with group of HBeAg negative cases and the healthy control group. It suggested considerable MDSCs might be involved in HBeAg immune tolerance. In addition, negative correlations between MDSCs/PBMC and parameters of ALT, AST and TBil, while positive correlation between MDSCs/PBMC and ALB parameter were found. Multiple comparisons between the four phases and health control phase again, there was a statistically sifnificant difference ($X^2=17.198$, p=0.002). Taken together, these findings may provide a new immunotherapy strategy for reduced the expression levels of MDSCs in CHB patients, through induction of an autoimmune response to virus removal.

  • The kidneys are exposed to toxicants and waste product and can be affected easily by these toxicants and by products of the metabolism. The consumption of adequate water is necessary to remove waste and to keep kidney healthy. Deficiency of liquid in the blood leads to various adverse effects on the kidney. The most common adverse deficiency of liquid in blood is deposition of solid matter in the kidney and subsequently formation of kidney stone. Nephrolithiasis (kidney stone) can be treated by drugs if it is small in size but if it blocks the route due to its big size then surgery is the only way to remove it. The recurrence rate of the problem is very high and it may reappear within 10 years. In Unani literature Hasāh wa Raml al-Kulya (nephrolithiasis) is described in detail. As per Unani literature stagnation of Ghalīz mādda (filthy and viscous matter) in the kidney is the main cause of the formation of kidney stone. Various single and compound formulations drugs are described for the management of kidney stone which are very effective as well as safe. Management is divided into two parts i.e. symptomatic treatment to relieve pain and to methods adopted to remove stone from the kidney. Musakkin-i-Waja'(analgesic) drugs are used for pain while Mufattit-i-Hasāh (lithotriptic) and Mudirr-i-Bawl (Diuretic) drugs are used to remove stone. Majoon Aqrab, Qurs Kaknaj and Dawa-e-Gurda etc. are compound drugs mentioned in literature for removal of kidney stone. Single drugs like Alu Balu, Tukhm Khayar, and Kharkhask etc. are also used for same purpose.
