    Notes: Abstract. We performed intraoperative ultrasonography with a miniature probe to explore the biliary anatomy, especially the cystic duct, during laparoscopic cholecystectomy. By using this radial-type probe introduced into a hard metal sheath with a balloon at the end, the plane containing Calot's triangle can be scanned easily when the gallbladder is extracted to the right side, thereby facilitating the identification of the cystic duct as well as the common ducts. In 30 cases, no common duct stone was found and the cystic duct was clearly identified. This radial-type miniature probe can be used to locate the cystic duct and avoid inadvertant incision or division of the common ducts.

    Notes: Abstract  Gluteal stepladder V-Y advancement musculocutaneous and fasciocutaneous flaps were used for resurfacing of various shaped sacrogluteal defects. A total of 27 patients with sacrogluteal defects were treated using this technique. Twenty-four patients had sacral pressure sores, 2 patients had a pilonidal sinus, and 1 had a low thermal burn of the gluteal region. The shape of defects varied including 12 elliptic, 5 inverted heart-shaped, 4 pentagon, 4 diamond, and 2 other shapes. There were no problems regarding flap survival even at the tip of step segments. In all patients, easy resurfacing of the defects and satisfactory recontour of the gluteal region was obtained without linear scars crossing the gluteal fissure. Since the segments of the flap are similar to the defect, defects of various shapes are easily covered, and trimming of normal skin tissue becomes unnecessary or minimal. On inserting a triangular flap in the gluteal fissure, excellent recontour of the sacrogluteal region can be achieved.

    Notes: Abstract  Topographic units of the face have been described previously. Recently, the miniunit has been used as a means of minimizing the sacrifice of normal remnant tissue. This paper describes a technique that considers the glabella subunit and miniunit and applies this principle to the required reconstruction.

    Notes: Abstract We present ab initio calculations of electric field gradients (EFGs) at impurity sites in ionic crystals TiO2, Al2O3 and CaCO3. The electronic structure was calculated self-consistently by the KKR method in the framework of the local spin density approximation of the density functional theory. The system with a single impurity was simulated by the super cell method. It was found that EFGs for the transition metal impurities (Sc, Nb, Cd and Ta) in TiO2 were well reproduced by the calculations if the charge state of them in TiO2 was taken into account. The present method was applied to the determination of the implantation sites of N and O nuclei in TiO2. The calculation of EFGs at a Si impurity in Al2O3 and at Ca site in CaCO3 were used to derive the quadrupole moments of 27Si and 39Ca from their quadrupole coupling constants.

    Notes: Abstract NaCl solutions containing carrier-free125mTe(IV) and125mTe(VI) have been prepared. The effect of the presence of various substances on the colloidal behavior of125mTe in solution has been studied by ultracentrifugation. It has been found that phosphate, sulfide and oxalate ions which complex with various elements decrease the colloidal formation of125mTe. In order to estimate the size of colloidal particles, the NaCl solutions containing carrier-free125mTe have been microfiltered through membrane filters with various pore size.
