The infratemporal fossa abscess is an irregularly shaped cavity, situated below and media to the zygomatic arch. It consists of masseter and nervus vascularis, etc. Comparatively speaking, the low position of the infratemporal fossa has almost freed the patient from dental, nasal,ocular and aural source of pain. So facial acupuncture is more likely to cause the infection. But it is also possible that the patient get cryptogenic infection of maxillofacial cavity, the treatment of which needs further study.

0.05).Conclusion:All the results of the five measurement methods showed that the condyle was located in the center of the fossa with a variation in the healthy adults in intercuspal position.The CBCT image of the sagittal middle layer of the joint could show the joint space accurately and has an important value in the research related to the changes of TMJ space.

The extreme microorganisms Ferroplasma spp., play an important role in bioleaching of sulphide ores at low pH value and temperatures around 50 degrees C. Without cell wall, Ferroplasma spp. is sensitive to pulp density, shearing force and heavy metal ions. Thus it is difficult to obtain their high cell density cultures, which limits the large-scale industrial application. In this paper, the optimum culture conditions of Ferroplasma thermophilum were studied by shaking culture. The results showed that the optimum culture conditions are as follows: 50 degrees C, initial pH 0.5, 50 mL working volume in 250 mL shaking-flask, inorganic nitrogen source (NH4)2SO4. The optimum combination of FeSO4.7H2O, yeast extract and peptone was determined by orthogonal experiments, including FeSO4.7H2O 40 g/L, yeast extract 0.3 g/L, peptone 0.2 g/L. Under the optimum culture conditions, the cell density was up to 6.3 x 10(7) cell/mL, and the oxidation of 40 g/L ferrous sulfate heptahydrate was finished in less than 72 hours. The results might provide information for scale-up of archaeon culture as well as its industrial application.

A case report of periprosthetic hip clostridium perfringens infection 13 years after total hip arthroplasty, the patient had hip pain with fever for one week. Physical examination and imaging examination confirmed the periprosthetic joint infection. The pathogenic bacterium was clostridium perfringens according to bacterial culture, and the pathogenic bacterium of clostridium perfringens was suspected relating to the gallbladder disease in this patient. Considering such periprosthetic joint infection was early stage hematogenous periprosthetic joint infection, treatment of debridement, retention of the prosthesis, irrigating, and indwelling drainage tube were conducted. By reviewing literature about periprosthetic clostridium perfringens infection, only seven reports of periprosthetic joint infection were caused by clostridium perfringens, which were all case reports. From the previous case reports and our case, we found that the infection around the prosthesis caused by clostridium perfringens was limited to the area around the joint, and prognosis of such cases may not be as severe as the natural gas gangrene which developed very rapidly, but great attention should be paid to. The hematogenous periprosthetic joint infection caused by clostridium perfringens who had gastrointestinal symptoms in the early stage should be highly suspicious of gallbladder lesions and thorough debridement, retention of the prosthesis, irrigating and indwelling drainage tube maybe a treatment method.
