The purpose of this study was to observe the effects of early loading on the surrounding bone tissue of the implants. 12 ITI HS implants (8 mm) were inserted on the mandible at 3 mongrel dogs. The implants were divided into two groups; the functional group was functioned with crown, and nonfunctional group was functioned without crown. After 3 and 5 months animals were sacrificed and specimens were examined using radiography, light microscopy, scanning electron microscopy. The following results were obtained. 1. On light microscopic and scanning electron microscopic examination, the difference in the amounts of bone attachment between 3 months loaded and unloaded implants were a little. Sometimes more bone attachment were observed in loaded implants. 2. Many osteoids surrounded the fibrous connective tissues indicating of bone remodeling were observed along the outer surface of the implants. 3. On clinical, radiographic, microscopic examination, epithelial downgrowths were not observed and bone attachments to the outer surface of the implants were observed in 3 months loaded and unloaded implants with good oral hygiene. 4. Epithelial downgrowths and crater-like bone resorptions were observed on 5 months loaded and unloaded implants with poor oral hygiene. 5. Many inflammatory cells in the epithelial tissue were packed in the hollow on 5 months loaded implants.

Purpose: This study was aim to examine the effect of extract from several herbs on wound treatment which are grown naturally in Namwon province. Methods: Adult male Sprague-Dawley rats were assigned to 6 of 2 group: control group (C, n=6), experimental group (E, n=6). Rats in E group had 3 sessions (everyday) for 4 days or 8 days of the extract treatment which was composed of German chemomile, Teatree and Lavender (CTL). Results: CTL extract on wound-induced mice showed significantly the increase of wound treatment rate (WTR), epidermal gap (EP) and collagen density (CD), compared with control. Conclusion: CTL extract may be a putative resources for cure or treatment of wound.
