Pulsatillae Radix and Cicadidae Periostracum have long been used for treatment of injuries, inflammations or itchiness in Korea. This study was carried out to examine the acne-remedy effects of the mixture made with equal parts of Pulsatillae Radix extract and Cicadidae Periostracum extract (PRCP) compared with 2%-benzoyl peroxide (Standard) used commercially as anti-acne. The results showed the mixture (PRCP) was more effective than each crude drug extract. The 10%-PRCP showed significant antimicrobial activity against Propionibacterium acnes, the major cause of acne, and also showed significant inhibition from type 1 $5{\alpha}$-reductase ($5{\alpha}R$), another cause of acne, And the cream made with PRCP demonstrated anti-sebum and acne-improvement effects on examinee's facial skin.

Acne, which intrudes the pilosebaceous unit, is a chronic inflammatory disease. The symptom of comedones, papules, pustules, cysts, nodules and scar mainly raise on the face, upper back, shoulder and neck. The cause of acne is the secreting growth of sebum, abnormal follicular keratinization, the form of group of propionibacterium acnes, and the response of inflammation etc. But the original mechanism of the cytobiologic level is exactly not known yet. Chungsangbangpungtang is one of the most frequently used medical treatments for the acne. A study on 25 patients with acne who took Chungsangbangpungtang shows that the oral medication of Chungsangbangpungtang is the best efficient remedy for a person who has acne less than one year without nodules.

This study was carried out to analyse a perception on acne for the Junior college students to provide basic data for the suitable treatment of acne to the students and the specialists. For this study, self-administering questionnaires were distributed to 480 students from 13 departments at a suburban women's junior college from May 1 to May 3, 1996. Of the students, 399 were responded and included in the analysis. The questionnaire includes the general question of objects, the question of knowledge and attitude of acne, and its treatment. The results were as follows: 1. Age distribution for the group less than 20 years was 63.7% and over 20 years was 36.3%, the group with acne was 66.2% and the group without acne was 33.8%. Proportions of acquiring the knowledge on acne was 49.6% from newspaper or magazine, 47.15 from friends, and 26.85 from TV or radio. 2. With regard to the knowledge on the presence of acne, a proportion of correctly answered for the question on the cause of acne was $3.41{\pm}1.02$ for the group with acne compared with $3.16{\pm}0.89$ for those without acne. This difference was statistically significant (p<0.05). 3. With regard to the knowledge levels on the treatment of acne, a proportion answered' skin-care center' for the question on where to select for the profer treatment was $13.21{\pm}1.88$ compared with $12.09{\pm}1.88$ for the other group. This difference was statistically significant (p〈0.05). A proportion of answered 'squeezing out acne by themselves' for the question of how to treat was $12.26{\pm}1.91$ compared with $10.83{\pm}1.25$ for the other group. 4. In the treatment according to the attitude of the group with acne, the positive group replied 'YES' in the intention of treatment by themselves was 55.9%. In conclusion, the differences in the knowledge and attitude on the presence of acne are not significant and it was found that the knowledge and attitude for the group with acne did not significantly influenced the treatment behavior. Accordingly, it is important to understand the cause of acne, provoking factors, remedy etc. For this, it is necessary to a provide an accurate information to professionals to enhance the knowledge of acne and to treat it properly.

Benign prostatic hyperplasia (BPH) is one of the most common diseases among elderly men. As the old-age population is increasing recently, it is to our interest to observe the growing BPH within them. In BPH, the dihydrotestosterone (DHT) acts as promotes prostate growth. It inhibits enzyme $5{\alpha}$-reductase that is involved in the conversion of testosterone to the DHT activity which reduces the excessive prostate growth. Through experiments, the effects of Phellius linteus water extract performed on the BPH rats were induced by testosterone treatments. For 12 weeks, Sprague-Dawley rats were treated with testosterone for the induction of BPH. Rats were divided into four experimental groups: the not treated group (N), the testosterone injection and D.W treatment group (TN), the testosterone injection and Phellinus linteus treatment group (TP) and testosterone injection and finasteride treatment group (TF). Prostate weight, volume and weight ratio in the TP group and the TF group were significantly lower than the TN group. Testosterone and DHT levels in the TN group were significantly higher than that of the N group. And the TP group was significantly decreased than that of the TN group. While prostates of control rats revealed severe acinar gland atrophy and stromal proliferation; the TP and TF groups showed trophic symptoms and were lined by flattened epithelial cells, thus, the stromal proliferation is relatively low as compared to the TN group. These suggest that Phellinus linteus water extracts may be an useful remedy for treating the benign prostatic hyperplasia.
