In 1982, we reported a case of recalcitrant urethritis caused by a strain of spectinomycin resistant PPNG. It caused a great fear that it might be the signal of an end of spectinomycin era, The disk-prediffusion method was used on all isolates from the Choong-Ku VD Clinic between August 1984 and December 1985 to screen out strains of N. gonorrhoeize resistant to spectinomycin, with disks containing 100pg of spectinomycin, Strains with inhibition zone greater tha.n 25 mm were considered susceptible, We could not disclose a single strain which wa.s resistant to spectinornycin, The reason why we do not see any more of spectinomycin. N. gonorrhoeae requires some speculation, It is possible that the mutant which had resistant to spectinornycin might not have teen quite stable and, after series of passage through human hosts, mutated back to original spectinornycin sensitive states. It is suggested that continual surveillance for spectinomycin resistant N. gonorrhoeae should be conducted.

PURPOSE:There is a clear sexual dimorphism in circulating concentration of leptin in adulthood. However, we don' know when such dimorphism begins and how much pubertal development influences on it. So we examined body composition and circulating concentrations of leptin according to Tanner stage(TS). METHODS:We examined 112 children(M; 56, F; 56, Age; 8.5-17 yr) to evaluate the relationship of leptin and body composition. Body composition was determined by bioelectric impedence measurements(BIA) and by anthropometry. Leptin was measured by human specific RIA. Leptin level was analysed according to TS, body mass index(BMI), fat mass(FM), and lean body mass. RESULTS:BMI and free FM was correlated with TS in both sexes. FM was closely correlated with TS in girls but not in boys(M; r=0.08, P=0.54. F; r=0.73, P>0.001). Leptin levels increased in girls with advanced TS(r=0.355, P<0.01), but decreased in boys(r=-0.339, P<0.01). A strong exponential relationship was observed for leptin levels with BMI, FM, and percentage body fat as determined by BIA. There was significant sexual dimorphism of leptin level at TS VI/V. Because leptin level was significantly related FM, leptin level was normalized to FM(Leptin/FM). Leptin/FM of females(0.67+/-.27 ng/mL/kg) was also significantly higher then that of males(0.31+/-.15 ng/mL/kg)(P<0.001). CONCLUSION: These data suggest that plasma leptin levels increase in girls and decrease in boys after TS II as pubertal development proceeds; they show a significant gender difference, especially late puberty, even after adjustment for FM. Sexual dimorphism in leptin during puberty reflects not only differential changes in body composition but also different leptin resistance; reference ranges of leptin could be modified by TS and gender.

Morquio's syndrome is a very rare disease, which is characterized by dwarfism, flattening of the vertebral body, marked spinal kyphosis, widespread affection of the epiphyses and normal intelligence. The authors experienced a case of Morquio's syndrome with typical clinical and radiological findings. The patient underwent bilateral supracondylar varus osteotomies for severe genu valgum deformities.

Objective To investigate the overweight status of military officers and soldiers and to analyze the risks of the induction of chronic diseases. Methods Questionnaires and biochemical analysis were used to randomly survey the living and training status of 485 officers and soldiers in a military unit. Blood and urine samples were collected and analyzed using blood biochemical analysis methods and conventional dry chemical methods. Statistical analysis was performed through EXCEL 2007 and SPASS 12.0 software. Results The survey results showed that the proportion of BMI abnormal people in the officers and soldiers was high. Compared to the normal population, the officers and soldiers with abnormal BMI had more bad daily life habits such as smoking and drinking, while their diet balance was relatively poor, and their frequency of daily exercise was significantly less. Biochemical tests showed that the proportion of the officers and soldiers with hyperuricemia and hyperbilirubinemia was high, but there was no significant difference in the officers and soldiers with different BMI. Urine analysis showed that the number of urinary protein and occult blood in the officers and soldiers increased significantly after military training, and the BMI abnormal population was more significant than the normal population. Conclusion There was a relatively low correlation between different BMI and chronic metabolic diseases in military officers and soldiers, but those with abnormal BMI were at high risk for exercise-induced kidney injury. Military officers and soldiers should strengthen health management and actively control the acquired factors that cause BMI abnormalities, to effectively prevent and reduce the BMI abnormality and lower the risk of induced early chronic kidney injury disease, promoting the overall health level.

PURPOSE: To find characteristic MRI features of vermian medulloblastoma. MATERIALS AND METHODS: MRI studiesand medical records were retrospectively reviewed for 12 patients with surgically proven midline medulloblastoma. The assessment concerned appearance of the mass in relation to surrounding structures ; MR signal intensity ; the enhancement pattern ; the mass's location and size ; presence of a cystic/necrotic area, calcification, or vascular void ; extension through the foramen Luschka ; degree of hydrocephalus ; and presence of tonsillarherniation. RESULTS: The midline medulloblastoma commonly showed roundish moon-surface appearance, especially onthe axial T2-weighted images. All tumors showed heterogeneous signal intensities mainly due to intratumoralcystic/necrotic or hemorrhagic changes. The tumors were commonly located at mid- and/or inferior vermis. Occasionally the tumors extended through the foramen Luschka, and caused obstructive hydrocephalus of moderate tosevere degree. Post-con-trast study showed heterogeneous, dense contrast enhancement in the majority of patients. CONCLUSION: The MR finding of the moon-surface appearance formed by both the mass and the intratumoralcystic/necrotic change as seen on axial T2-weighted images could be helpful in the diagnosis of vermianmedulloblastoma.

PURPOSE: Idoxifene is currently entering phase II clinical trials for the treatment of advanced breast cancer. The radiolabeled idoxifene using 123I provides an opportunity for clinical pharmacology with single photon emission computed tomography (SPECT). The purpose of this study was to prepare radiolabeled idoxifene using 123I and to determine its cell uptake of breast cancer cell line. MATERIALS AND METHODS: With a view to evaluating new anticancer drugs, we are investigating the novel antiestrogen pyrrolidino- 4-iodotamoxifen (idoxifene). [123I]Idoxifene has been prepared in no-carrier-added form using a tributyl stannylated precursor which has been synthesized by means of (2-chloroethoxy)benzene with (+/-)-2- phenylbutanoic acid on the basis of previously reported standard methods. The biodistribution and dynamic behavior of the compound were investigated using the comparative breast cancer cell line, MCF-7 (estrogen receptor-positive) and MDA-MB-468 (non-estrogen receptor). RESULTS AND CONCLUSION: Acylation of (2-chloroethoxy)benzene with (+/-)-2-phenylbutanoic acid gave the versatile ketone (81%) which reacted with 1,4-diiodobenzene to give triphenylethylene as a mixture of E and Z geometric isomers, which were separated by the recrystallization in ethanol. The E-isomer was treated with pyrrolidine to give idoxifene (67%). In order to incorporate radioactive iodine into the 4-position, the 4-stannylated precursor was prepared (30%). The yield of radioiodination was 90-92% with a high radiochemical purity greater than 98%. The ratio of tumor uptake of the breast cancer cell line between MCF-7 and MDA-MB-468 was about 1.7.
