The presence of epicanthal folds in Asian eyelids is one of their unique features, in combination with the lack of supratarsal folds. Western culture has influenced many people to prefer to eliminate the prominent epicanthal fold. A number of surgical techniques have been suggested for their correction. However, difficulty with design, excessive and prominent scarring of medial canthal and nasal area, recurrence, and rigidity of application are potential problems associated with many procedures. This paper describes a epicanthoplasty with three-dimensional Z-plasty. Through epicanthal fold incision, the medial canthal tendon is medially advanced and sutured to the periosteum of nasal bone. After the transposition of the flaps, trimming of the flap is usually required. Three-dimensional Z-plasty creates the attractive eyes. From March, 1995 to March, 1997, the technique was applied to 37 patients with epicanthal fold and was performed with or without double-fold operation. There were 34 females and 3 males with ages ranging from 17 to 30 years. Through 2 years follow-up, this technique has delivered esthetically good results with minimal postoperative scar and could made the reduction of ICD from 40 ± 2.13 mm to 34 ± 1.98 mm. The advantages of epicanthoplasty procedure using three-dimensional Z-plasty(Yoon's method) are as follows; 1) simple in design 2)minimal postoperative scar in the medial canthal area 3) versatile in its application 4) no recurrence 5) no hypertrophic scar 6) preserving ethnic identity.

This report describes the comparisons of mitoses in the hepatic parenchymal cells and in the tile duct cells following administration of CCl4 and CCl4 with Lysine. Histopathologic appearances and the growing body weights were also observed. 1. The slowing ratio of the body weights in the ducklings administered CCl4 with Lysine was more increased in the experiment than those of the body weights in the ducklings administered CCl4. However, the slowing ratio of the body weights in the ducklings administered CCl4 with Lysine was more decreased in the experiment than those of the body weights in the control. 2. Necrobiosis and fat changes were observed in the lifers of the ducklings administered 0.1ml CCl4. 3. The mitotic figures in the hepatic parenchymal cells were more increased in the ducklings administered CCl4. The figures were also more increased in the third week than those in the first week. 4. Mitotic figures in the bile duct cells were more increased in the ducklings administered CCl4 and CCl4 with Lysine than those in the control. The figures were more increased in the third week than those in the first week.

This study was carried out to investigate the histological changes of rat liver by repeated treatment of cyclosporin A that has been widely used for treating some autoimmune diseases and immunosuppressive drug in organ transplantation. 70 Sprague-Dawley rats were kept in experimental circumstances for 2 weeks and 50mg/kg B.W of cyclosporin A was injected once a day subcutaneously for 7 days and sacrificed at 1 hour, 1 day, 3 days, 7 days, 14 days, 28 days after the last injection. Histological changes were observed by H & E, Oil red O, and Masson trichrome stains and the results obtained were as follows. 1. 26 percent of animals has died during the treatment of cyclosporin A, and the animals survived were observed to be dull and inactivated. 2. The mild cytoplasmic changes of hepatocytes in portal area were observed by H & E stain in 1 hour lapse group and this finding was recovered with time lapse. 3. The lipid accumulation in periportal areas was observed in 1 hour and 1 day lapse groups and this finding was recovered with time lapse. 4. Although the cytoplasmic changes and lipid accumulation were started in the portal area and moved to intermediated and central areas, the changes in the intermediate and central areas were not as severe as that of portal area. 5. No specific increase of connective tissue was observed in all groups. 6. Histological changes of rat liver induced by cyclosporin A were recovered with time lapse, and the entire recovery was observed in 28 days lapse group after the last injection.

배추를 다듬기 하는데 발생한 폐기량은 7.5∼14% (w/w)이었고 10±2℃에서 30일간 방치한 경우 약 17∼25% 발생하였다. 간절임 배추의 pH값은 저장온도가 낮을수록, 염도가 높을수록 높았으나 calcium chloride 첨가가 절임배추의 pH값의 변화에는 영향을 주지 않았다. 유리당의 함량변화는 최소 약 4% 수준에서 산의 함량과는 반비례적으로 변화하여 저장 90일에는 소금농도가 낮고 저장온도가 높은 경우 적게 감소되었다. 균수변화에서 세균과 효모는 전 기간을 통해 증가한 반면, 곰팡이는 감소하였다. 한편 산의 첨가와 CaCl? 첨가시 소금으로만 절인 경우보다 세균과 효모는 낮은 속도로 증가했다. 저장중 경도는 온도가 낮고 염도가 높으며 젖산을 첨가한 경우 다소 높게 유지됐고, CaCl? 첨가의 경우 잎과 줄기에서 월등히 높았다. 휘발산과 불휘발산의 함량변화에서 온도가 낮고 염도가 높은경우 불휘발산의 함량이 낮았는데 특히 젖산 첨가시 불휘발산의 증가를 억제하는 것으로 나타났다. flavor score 는 저온과 고염도 젖산첨가시 유리하였다. This study was to investigate the effects of storage temperature, lactic acid and calcium chloride addition about the pH values, sugar content, firmness, volatile and nonvolatile acidity, microbial counts and flavor of the salted chinese cabbages during storage (90 days), and trim loss of chinese cabbages during the trimming of raw and storaged (30 days) chinese cabbages. The waste rate was in the course of trimming of raw chinese, cabbages was 7.5-14(w/w). The proportion of trim loss was highly correlated to sunshine duration, temperature, humidity and handling for the storage. Free sugar was decreased fast and much in the case of high temperature and low level sodium chloride in comp rison of low temperature and high sodium chloride, but ?? and lactic acid did not affect its changes. Time to reach the lowest pH values were fast in the case of high temperature and low salt content. Lactic acid affected inital pH value (4.38-4.57) and constant pH value in each case was increased at low salt content, at high temperature, and then the pH values were slowly increased when volatile acidity was increased. Firmness was high in the case of addition of lactic acid and calcium chloride, low temperature, high sodium chloride concentration. Especially, calcium chloride addition remarkably showed high firmness. Flavor score was high in the case of low storage temperature, high yeast counts were slowly increased in spite of low temperature and high salt content, but mold counts were slightly increased during all period Lactic acid, low temperature and high sodium chloride were effective to inhibit the growth of microorganisms. Volatile and nonvolatile acidity was increased during all storage period ; however, lactic acid and low temperature storage inhibited their increase. To conclude, quality of salted chinese cabbages was effective at low temperature storage, lactic acid and calcium chloride addition, and high salt concentration.

The regulation of cell death and renewal is controlled by androgen in rat ventral prostate. So many studies on androgen block effects has been performed to understand the hormonal control in prostatic epithelial cell. Castration of rat results in activation of programmed cell death of ventral prostate. This response is related to activation of the calcium-magnesium dependent endonuclease. To observe the changes of regression of prostatic gland following androgen withdrawal, histologic examination was performed in rat ventral prostate after castration. The level of serum testosterone was rapidly decreased after castration from 5.9 ng/ml in normal rat to 1.6 ng/ml at 3hr castration. After 6hr postcastration its level was 0.01 ng/ml or below. The pathologic changes of ventral prostate was also observed after castration. Apoptosis in the ventral prostate appeared initially at 24hr postcastration but maximal apoptosis was noted at 6days. We confirmed the apoptotic bodies in light microscopic examination be electron microscopic observation.

Effects of acute exposure to alcohol on fine structures of cerebellar Purkinje cells were investigated with electron microscope. ICR mice were injected orally by 18ml/kg b.w. of ethanol, and 30 minutes,2 hours, 6 hours, 24 hours, 3 days, 7 days after administration, mite were sacrificed with perfusion fixation. Specimens of each group were obtained by routine electron microscopic tissue preparation and were observed with transmission electron microscope. Dilatation of cisternae of rough endoplasmic reticulum, multiplication and cisternal dilatation of smooth endoplasmic reticulum, morphologic changes and cisternal dilatation of Golgi complex, swelling of mitochondria, increase of lysosome were prominent findings in the groups of 30 minutes and 2 hours after alcohol administration. These findings were getting recovered with the lapse of time. The territorial regions of astrocytes were prominently extended, and the synaptic vesicles of auto-somatic synapses were reduced in all experimental groups. These findings were also recovered gradually with the lapse of time, but these observations even in the group of 7 days after alcohol administration were not completely similar to that of control group.

박만수,이중화,윤율로,설종구 충남대학교 의과대학 지역사회의학연구소 1991 충남의대잡지 Vol.18 No.1

Atypical mesoblastic nephroma is a rare infantile renal tumor that may behave aggressively in older infants. The features that distinguish atypical mesoblastic nephroma from congenital mesoblastic nephrorma are as follows; (1) atypical gross features consisting of one or more of the follwing: flesh areas, foci of hemorrhage, necrosis, involvement of adjacent structures; and (2) high cellularity and mitotic index. Treatment is not established whether additional modes of therapy are indicated in completely resected atypical mesoblastic nephroma. A close and regular periodic follow-up is indicated in all cases of atypical mesoblastic nephroma. A case of atypical mesoblastic nephroma in 45-day-old-male is presented with brief review of literatures.
