OBJECTS: Sanjoin, the seeds of Zizyphus vulgaris var. spinosus has been used as the most important hypnotic agent in chinese medicine to treat insomnia. This research was performed in order to examine the effect of betulinic acid and sanjoinine-A which are components of Sanjoin. METHOD: Sleeping time, sleep recordings of EEG, serum serotonin level, and locomotor activity were measured in rats which received betulinic acid and sanjoinine-A as sleep induction material extracted from Sanjoin. RESULTS: 1) Groups received betulinic acid, sanjoinine-A, and lorazepam showed increased sleep time than control group with saline. 2) Groups with betulinic acid, sanjoinine-A, lorazepam and saline recorded beta-wave in sleep recording of EEG. In there was no significant difference among all groups. 3) No significant difference in serum serotonin level among all groups was found. 4) In autonomic activity testing, groups of betulinic acid, sanjoinine-A, and lorazepam showed significantly more decreased in activity than saline group. In comparison of groups of betulinic acid and sanjoinine-A with a group of lorazepam, there was no significant difference. CONCLUSION: These results suggests that betulinic acid and sanjoinine-A have the sedative effect like lorazepam rather than sleep effect.

BACKGROUND: A clinical study of rosacea has never been reported in Korea. OBJECTIVE: The purpose of this study was to elucidate the clinical observations of rosncea. METHODS: During a 5-year-period from Jan. 1990 to Dec. 1994, 133 patients were evaluated with regard to age, sex, location of skin lesions, clinical type, duration, and precipitating factors. RESULTS AND CONCLUSIONS: 1. Of the 7,787 cases amongst outpatients, 133 cases(1.7% ) were dignosed with rosacea. Of there 46 were male patients and 87 females, giving a sex ratio of 1:1.9 in favor of females. 2. The most common type of rosacea was vascular rosacea(60.2%) 3. The average duration of rosacea was 3.4 years. 4. Rosacea afflict persons aged 40-49 most frequently. 5. The predilection sites of the rosacea were : cheek(42.9%), nose(23.3%), entire face(11.3%), cheek & nose(9%), zygomatic area(6.8%), extra-facial area(3.8%), forehead(2.9%). 6, The aggravating factors of rosacea were : unknown cause(32.3%), coffee & tea(18%), alcohol(13.5%), emotional stress(10.5%), sun exposure(9.8%), multi-factoral(7.5%), drugs(steroids)4.6%).

Vertebral pedicle screws have been widely used for secure posterior spinal fixation. When postoperative CT scan films were made, the blurring of pedicle screws were observed and we could not figure nut the exact diameter of screw and canal encroachment. There is no information in the difference hetween actual diameter and measured diameter of pedcile screws in CT yet. In this study, we try to find out partial voiume averaging artifact of pedicle screws made of stainless steel and titanium. Partial volume averaging artifact occurs when the shape of an object changes within the thickness of the CT slice or when a relatively small object is only partially included within the slice. Four pig cadaveric spinal column including 6 vertebrae each were prepared and CT scans were performed after insertion of C-D screws(stainless steel) to the left and TSRH screws(titanium) to the right pedicle. Another CT scans were performed after insertion of C-D screws to the right and TSRH screws to the left pedicle. The third CT scans were made after removal of all the pedicle screws. Actual C-D screw diameter was 6mm and CT scanned diameter was 8. I 6+/-0.66mm. Actual TSRH diameter was 6.5 mm and CT scanned diameter was 6.59+/-0.34mm. In conclusion, stainless steel has more partial volume averaging artifact than titanium. Safety margin of pedicle screw made of stainless steel is about 2mm and that of titanium is about 1 mm.

Significant traumatic disruption of the ligaments about the knee can occur in a child. Recently several reports have described knee ligament, injuries with open growth plates. And these reports contradict the notion that complete tears of knee ligaments occur only after growth plates have closed. The youngest patient with medial collateral ligament injury reported before was a 4-year-old boy by Joseph and Pogrund in 1978. But authors experienced a case of ruptured medial collateral ligament of the knee in a 2-year and 1-month old boy, who seemed to be youngest with the ligament injury.
