OBJECTIVES: The early detection of ectopic tubal pregnancy in unruptured state is increased as the transvaginal sonography and sensitive serum hCG test are available. For this unruptured tubal pregnancy, the medical treatment using methotrexate via various routes and dosage is being tried. Our study was to evaluate the efficacy of single systemic injection of methotrexate in the treatment of unruptured tubal pregnancies. Material and METHODS: From the January 1997 to July 1999, of 152 ectopic pregnancy patients, 22 patients who were diagnosed as unruptured tubal pregnancies were treated with single-dose systemic methotrexate injection (50 mg/m2/IM). Exclusion criteria were unstable vital signs with hemoperitoneum, adnexal mass > 5-6 cm. Serum hCG titers were checked before injection and 4, 7 day after injection. If serum hCG titer declined more than 15% on 7 day after injection compared with titer on 4 day, the weekly hCG titer was followed until it was <10 mIU/ml .If the hCG titer did not decline more than 15 %, a second dose was given. If hCG titer was not decreased or vital signs became unstable after 1-2 injections, the treatment was considered failure and surgery was done. RESULTS: 18 cases (82%) of 22 were successfully treated with single-dose methotrexate. The mean size of ectopic mass and initial serum hCG titers were 2.7+/-1.3 cm (range, 1.5-5.4 cm) and 3,298+/-1,007 mIU/ml (range, 132-12,239), respectively. Of 22, 6 cases (28%) needed second dose of methotrexate. The mean time to resolution of serum beta-hCG titer was 27.5+/-13.6 days (range, 8-53 days). Elevation of liver enzyme did not occurred in all cases during treatment. Initial hCG titer was more important prognostic factor than ectopic mass size for successful medical treatment. CONCLUSION: Single-dose methotrexate appears to be an effective medical treatment for the unruptured tubal pregnancy. However, patients selection using strict criteria is needed to increase its success rate.

The author measured the severity of brain damage of 36 rabbits irradiated 2.45 GHz microwave for 10 minutes, 20 minutes and 30 minutes, respectively. Electromicroscopic and light microscopic findings of just after, 1 weeks, 2 weeks and 4 weeks after irradiated brain were compared in each time. Swelling and vacualization of nerve cell and mitochondria were noted. Also these changes tend to increased severity along amount of radiation, but revealed reversible changes with time. Myelinated and unmyelinated nerve fibers were examined as same manner. These nerve fibers also revealed swelling and vascuolization, these findings also tend to increase severity with irradiation power and more prominent at unmyelinated nerve fibers. Reversability of these findings after each time period were more prominent in myelinated nerve fibers than unmyelinated nerve fibers.
