  • 1. Objectives This study is written to investigate the biblographical facts on the book ${\ulcorner}$ Geumge Bibang${\lrcorner}$(Secret Prescriptions of Sasang (Golden Box). 2. Methods The Biblographical study through chronological research of several books concerning Sasang Constitutional Medicine including ${\ulcorner}$Dongyisusebowon${\lrcorner}$,${\ulcorner}$Dongyisasangjintyoeuijeon${\lrcorner}$after Dr. Lee Je-Ma's death was accomplished. 3. Results and Conclusions There are so many herb medicines using just one herb drug not several herb drugs according to many diseases in this book. Accrording to the writer of this book, Lee Min- Bong, JUSt one herb drug to each disease was a useful way to treat that disease in a poor countryside life. There are 85 adult's diseases, 8 women's diseases, 47 children's disease, 11 smallpox's diseases and 30 grotesque diseases. This book of ${\ulcorner}$Geumgebibang${\lrcorner}$ was written by Lee Minbong not by Cheondeoksanin in 1935 and published in 1936 and it was the first book covering the herb drug and diets to treat diseases according to Sasang Constitutional Types. It was first found in this book that Sasang could be explained with Yin- Yang relationship and Sasang Constitutional Types could be explained with characters like dragon, cow, donkey and horse, and with classrncatibn of faces and behaviors.

  • Sulfamethoxazole particles were microencapsulated using the gelatin-acacia complex coacervation method. Micromeritic properties and dissolution characteristics of the microcapsules were studied. The particle size distribution followed log-normal form. As the hardening time increased, the particle size and wall thickness increased ($45.3-52.0\;{\mu}m$, $2.02-5.12\;{\mu}m$, respectively). This is considered to be due to the cross-linked wall structure of formalized microcapsules which prevents shrinking of gelatin during the dehydration and drying processes. An increase of hardening time clearly delayed the release rate. The in vitro 50% dissolution time $(t_{50})$ for unencapsulated sulfamethoxazole powder was less than 3 min.; for microcapsules hardened for 30 min, the $t_{50}$ was 20.1 min.; for those hardened for 60 min. the $t_{50}$ was 25.0 min.; for those hardened for 120 min., the $t_{50}$ was 35.8 min. The surface of the unhardened microcapsules was smooth and had no cracking or pore penetration. However, the surface of the hardened microcapsules was folded and invaginated.
