Objective: To investigate the application of microemulsion TLC in separation and identification of various effective compositions in traditional Chinese patent medicines. Methods: The various compositions in Kangganmao Granules and Fangfeng Tongsheng Pills were separated and identified simultaneously on polyamide film with six kinds of SDS/n C 4H 9OH/n C 7H 16 /H 2O microemulsions as the mobile phases. Affections of kinds and acidity on separationg results of microemulsions were investigated. Results: The baicalin, chlorogenic acid, Saposhnikovia and glycyrrhiza in Kangganmao Gronules and the emodin, chrysophanol, baicalin, Saposhnikovia and Glycyrrhizae in Fangfeng Tongsheng Pills may be separated and identified simultaneously with microemulsion (containing 75% water) formic acid (9∶1) as mobile phase. Conclusion: Microemulsion TLC is an efficient, simple new method for the separation and identification of various compositions in traditional Chinese patent medicines.

A total of 40 adult black-mice was used and divided into two groups for expeiment. Group A was irradiated by UVB only and Group B had SPF 15 sunscreen a.pplied to the back followed by irradiation by UVB. Each group was divided again into 5 subgroups according to the days of UVB irradiation frcm 2 to 10 days. A Waldmann combination UVA+UVB Radiation Treatment Cabin 8001 was used as the light source and the UVB dosage was 50 mJ/cm2 daily. Skin specimens were taken 24 hours after the last irradiation. Histologic changes in epidermis were reviewed by the light microscope. In group A, the characteristic sunburn cells(SBC) were observed with 100 mJ/ cm2. SBC number was maximum with 400 mJ/cm2. The other epidermal changes were parakerat.osis, crusts, atypical cells, and mitoses of basal cells, which showed graded responses to the UVB doses. Pretreatment with the sunscreen completely prevented these changes.

We report an unusual case of sebaceous hyperplasia in an 18-year-old male manifestated clinically as yellowish, grouped papules with a linear distribution, present on the right side of forehead since birth. Histopathologically, a large sebaceous gland composed of numerous lobules grouped around a centrally dilated duct was seen. The sebaceous lobules distributed in the upper dermis showed direct connection to the skin surface, which suggested a transepidermal elimination of sebaceous lobules.

OBJECTIVE: Hysterectomy is one of the most common gynecological operations. The objective of this study is to compare the efficacy of suturing methods of vaginal cuff between laparoscopic and vaginal approach. METHODS: One hundred and sixty one cases of laparoscopic hysterectomy were devided into two groups. In group A(n=67), vaginal cuff was sutured by laparoscopic suture technique and in group B(n=94), vaginal cuff was repaired by vaginal approach. RESULTS: There were no significant differences in uterine weight, hospital stay, pre-and postoperative hemoglobin level and complications including febrile morbidity in two groups. Operation time was significantly shorter in group B(p=0.05). CONCLUSION: Transvaginal repair of vaginal cuff showed shorter duration of operation time than laparoscopic suture technique in total laparoscopichy sterectomy.

We experienced three cases of non-giant congenital nevus. They showed zosteriform or heart-shaped grouping of pigmented papules which were pierced by hairs. Histopathologic examination disclosed nevus cell infiltration in and around hair follicles and in the upper two thirds of reticular dermis. We would like to report these cases as follicle-centered spotted grouped pigmented nevi.

The pulmonary arterial pressure(PAP) was reported to be higher in essential hypertensives than in normotensives, but the underlying mechanisms for the higher PAP were not known exactly. In order to observe the changes of pulmonary hemodynamics and to get an insight into the mechanism of the pulmonary hypertension, if any, in essential hypertensive patients, the autors performed the cardiac catheterization in 13 normal controls(group A), 14 coronary patients with normal systolic left ventricular function and systemic blood pressure(group B), and 15 essential hypertensives with normal coronary artery and systolic left ventricular function(group C). 1)Pulmonary arterial pressure(PAP) was 19.2+/-3.2/8.1+/-1.9/12.0+/-1.9(s/d/m)mmHg in group A, 25.0+/-6.2/12.8+/-4.0/16.3+/-4.5mmHg in group B, 29.3+/-6.1/12.8+/-4.0/18.2+/-3.6mmHg in group C. The PAP was higher in group B and C than that of group A(p<0.005). 2) Pulmonary vascular resistance(PVR) was 88.2+/-34.9 dyne.sec.cm(-5) in group A. 137.8+/-74.5 dyne.sec.cm(-5) in group B and 173.9+/-77.5 dyne.sec.cm(-5) in group C. In group B and C, PVR was increased compared to that of group A(p<0.05, p<0.005, respectively). 3) Pulmonary capillary wedge pressure(PCWP) was 6.6+/-2.8 mmHg in groupa A. 9.9+/-2.9mmHg, and 9.6+/-3.6 mmHg in group C. PCWP in group B and C were higher than that of group A(p<0.005). 4) Systemic vascular resistance(SVR) was 1298+/-340 dyne.sec.cm(-5) in group A, 1466+/-362 dyne .sec.cm(-5) i group B and 2255+/-439 dyne.sec.cm(-5) in group C. In group C, SVR was increased compared to that of group A and B(p<0.002). 5) Significant correlation was demonstrated between PVR and PCWP in group A(r=-0.74, p<0.05). 6) In group B, significant correlations were shown between PAP and PCWp(r=0.55, p<0.05), between PAP and PVR(r=0.69, p<0.05). 7) In group C, significant correlations were demonstrated between PAP and PCWP(r=0.55, p<0.05), between PVR and SVR(r=<0.51, p<0.01). Above results revealed that PAP and PVR were increased in essential hypertensives without left ventricular failure and this elevated PAPseemed to be affected in part by increased PCWP, and increased PVR in accordance with increased SVR.

The case of a 56-year-old woman with a keratoacarithoma(KA) of the labial mucosa is herein reported, The tumor was excised and the pathological features were characteristic of a KA, This case is reported because the oral mucosa is such an unexpected location for solitary KA and the labial mucosa of this patient received chronic actinic damage, which suggested an etiological relationship. Follow-up examination of the patient after four months showed no recurrence.

Authors carried out the experimental study to investigate whether the Paragonimus westermani would uptake the blood in the parasitic definitive host, and also tried for the amount and distribution of the blood which would be harbored in a worm body, and so on. Experimental animals used in this study were dogs and cats, and they were infected with metacercariae of P. westermani. Several months later of the infection, Cr(51) tagged red blood cells were administered to each animal, and the animals were sacrificed and autopsy was done after 24 or 48 hrs of the administration. One part of the detected P. westermani adult worms of each animal were bred in Tyrode's solution and the others were killed by fixing in formalin solution. By Well-type scintillation counter, the radioactivities were measured for the alive and killed worms and of the blood of each experimental animal which was collected at autopsy . In conclusion, it was found that P. westermani worms uptake blood in parasitic definitive host, and amount of the blood harboring in a worm of 56 infection-days(size of worm; 4 x 3 x 1 mm) was 0.002 ml, 0.004 or 0.005 ml in 103 infection-days(size of worm: 8 x 5 x 3 mm) and 0.011 ml in 217 infection-days(size of worm: 9 x 7 x 4 mm). Almost of the whole blood uptaked in the worms was distributed in intestine. It was observed that the blood uptaked in the worm body was excreted continuously through the excretory pore, so that the radioactivity could not measured almost completely in cases of 24 hrs-breeding worms.
