PURPOSE: To evaluate leptin values in placental cord blood of newborns with normal intruterine growth after 30 weeks of gestation and to study the relationship of leptin with gestational age, birth size, ponderal index, BMI, placental weight, gender difference, Insulin-like Growth Factor-I(IGF-I) and Insulin-like Growth Factor binding protein-3(IGFBP-3). METHODS: Ninety healthy newborns(49 males and 41 females) with normal intrauterine growth were studied. They were classified into 4 groups according to the gestational age(GA):group I(30-33 weeks GA, n=17), group II(34-36 weeks GA, n= 24), group III(37-39 weeks GA, n=32) and group IV(40-42 weeks GA, n=17). At the time of delivery, newborn infant' weight, length, head circumference and placental weight were measured and BMI, ponderal index were calculated. A venous cord blood sample was collected at the time of delivery and serum leptin(RIA), IGF-I (IRMA) and IGFBP-3(IRMA) were measured. RESULTS: Cord blood leptin correlated positively with gestational age(r=0.730, P>0.01), body weight(r=0.686, P<0.01), length(r=0.419, P<0.01), head circumference(r= 0.498, P<0.01), BMI(r=0.750, P<0.01), ponderal index(r=0.704, P<0.01), placental weight(r=0.536, P<0.01), IGF-I(r=307, P<0.01) and IGFBP-3(r=0.736, P<0.01). Multiple linear regression analysis showed BMI, IGFBP-3 and sex(female) were independent predictors of leptin values. Leptin values increased progressively throughout gestation. Mean leptin values of group II(3.90+/-.28ng/mL) were significantly higher (P<0.01) than those of group I(1.92+/-.09ng/mL) and also values of group III(5.37+/-.52ng/mL) were higher than those of group II(P<0.05). But there was no significant difference between group III and group IV(6.45+/-.36ng/mL). Mean leptin values in females(5.07+/-.54ng/mL, n=41) were significantly higher than in males(4.07+/-.76 ng/mL, n=49) but there was no inter-gender difference in body weight, BMI, ponderal index, IGF-I, IGFBP-3. In addition, mean leptin values in females(7.45+/-.07 ng/mL) were significantly higher than in males(5.02+/-.09ng/mL) after 40 weeks of gestation. CONCLUSION: BMI, IGFBP-3 and sex(female) were independent predictors of leptin values. Leptin values increased significantly after 34 weeks of gestation and females had higher leptin values than males, especially in fullterm newborns. Leptin values in newborns had higher correlations with IGFBP-3 than with IGF-I as gestational age increased.

A case of right ovarian vein syndrome is reported with a review of literature. The patient presented was a 29 year-old multipara and eighth month of pregnancy. The extirpation of entire right ovarian vein, including it's all tributaries produced a good result and has not caused interruption of pregnancy. The clinical situation due to aberrant right ovarian vein is probably more frequent than heretofore suspected, by reason of a frown of X-rays during pregnancy and also an unawareness of the condition. Therefore, if clinical observations and X-ray studies are performed, more cases of such a condition. will be expected.

PURPOSE: To evaluate the MR findings of embolized cerebral arteriovenous malformations according to various embolic materials. MATERIALS AND METHODS: We performed the endovascular embolization using four different kinds of embolic materials in 33 patients. Embolization related changes in the nidus and surrounding brain parenchyme were analyzed and the results were compared with pre- and postembolization MRI, CT and anglographic findings in all patients. RESULTS: Embolized vessels with N-buthyl-2-cyanoacrylate(NBCA) mixture showed some artifact in CT due to metallic character of tantalum powder or fatty nature of lipiodol. But in MRI, it was represented by fatty signals without artifact. In cases of using polyvinyl alcohol and ethylene vinyl alcohol copolymer(EVAL), there were no specific signal by the embolic material except for the disappearance of flow related signals in feeding arteries and shrinkage of venous ectasis. CONCLUSION: MRI is a valuable imaging modality for analysing the morphology and hemodynamics of cerebral AVMs, especially after embolization of pathologic vessels. Recognition of the signal of embolic agents and thus the thrombosed portion could lead to more precise analysis before surgery or radiosurgery.
