25 cultivars of perilla seeds were stored in air dry room condition after harvest. Seed samples were taken from the seed in storage and tested for germination at 25℃ to study the natural dormancy of the perilla seed. In air dry room, natural dormancy periods ranged from 51 to 71 days in cultivars for leave, from 28 days of the shortest ‘Daegugal’to 78 days of the longest ‘Daemyounghuk’in oil seed cultivars, and from 18 days of the shortest ‘India’to 61 days of ‘Baegimsogal’and ‘Hugim’. Dormancy period of ‘Jukjaso’was 152 days and other cultivars in Jaso group ranged from 62 to 72 days. The seeds of seven cultivars of perilla were stored in various levels of relative humidity from November 11 to March 31 Following year. Germination of ‘Gimhae’and ‘Gyungsanbaek’was conspicuously delayed at low storage humidity. The dormancy period of two cultivars were 51 days after harvest at RH100% and 121 days and 131 days at RH 30%, respectively. Thus, the lower storage humidity, the longer dormancy period. Above results indicate that excessive drying of perilla seeds after harvest causes inferior germination and delays dormancy break. Therefore, perilla seed should not be stored in excessively dry condition.

The twenty newborn infants with periventricular leukomalacia(PVL) who were admitted to the neonatal intensive care unit of SoonChunHyang University Hospital from May 1, 1993 to July 30, 1997, were investigated for risk factors. Control group were the age matched 20 neonates who were admitted at the same time of study period. The results were as follows: 1) Mean gestational age was 31 week and mean birth weight 1665gm. 2) PVL's were located in the parietal region in 10 cases, fronto-occipital in 7 cases and parieto-occipital region in 3 cases. 3) Multiple logistic regression analysis for the risk factors of PVL showed that low birth weight, intraventricular hemorrhage, bronchopulmonary dysplasia, necrotizong enterocolitis and ventilator apply were the most significant contributing factor(P<0.05). 4) In a follow-up ultrasonograptic findings, 11 among 14 neonates with localized PVL were normalized whereas, all of 6 extensive PVL had the sequale of ventriculomegaly or cerebral atrophy. 5) In a follow-up neurologic examination, the poorer sequale including spastic diplegia or quadriplegia was associated with the larger, the more extensive PVL.

<P><B>Background and Purpose—</B></P><P>The aims of this study are to evaluate the risk factors for symptomatic ischemic complication (symptomatic ischemic complication [SIC], transient ischemic attack, or stroke) and microembolisms detected as MR diffusion-weighted imaging (MR-DWI)–positive (DWI(+)) lesions, and the relationship between DWI(+) and SIC after coiling of unruptured intracranial aneurysm.</P><P><B>Methods—</B></P><P>Between March 2009 and November 2011, 382 unruptured intracranial aneurysms in 343 patients underwent both coiling and posttreatment MR-DWI. The incidence of and risk factors for SIC and DWI(+), and the relationship between DWI(+) and SIC were retrospectively analyzed.</P><P><B>Results—</B></P><P>The incidence of SIC was 4.1%. The incidence of DWI(+) was 54.5%. The number of DWI(+) lesions was significantly larger in the SIC group, than in the asymptomatic one (12.1±10.4 versus 5.0±8.7, <I>P</I><0.00). The cutoff value of DWI(+) for predicting SIC was ≥6 (sensitivity 85.7%, specificity 70.7%). The patients with DWI(+) ≥6 was 28.6%. Of the patients with SIC, the patients with DWI(+) ≥6 was 78.6%. Patients aged≥65 years had a trend for SIC, and it was the only independent risk factor for DWI(+) ≥cutoff (n=6; 95%CI, 1.167–3.083).</P><P><B>Conclusions—</B></P><P>The number of DWI(+) lesions was significantly larger in the SIC group than in the asymptomatic one after coiling of unruptured intracranial aneurysm.
