PURPOSE: To compare the efficacy of 3 different eye ointment instillations with eyelid taping and eyelid taping alone to prevent eye complications during surgery under general anesthesia. METHODS: A total of 296 eyes of 148 patients who underwent general anesthesia for at least 60 minutes were randomly assigned to 1 of the following 4 groups: group A, eyelid taping alone; group B, eyelid taping with solcoseryl ointment; group C, eyelid taping with carbomer ointment; group D, eyelid taping with lanolin ointment. Schirmer test, tear film break-up time (TF-BUT), conjunctival hyperemia scale (CHS), National Eye Institute corneal staining scale (NSS), and ocular surface disease index (OSDI) were prospectively evaluated before and after general anesthesia. RESULTS: TF-BUT was significantly increased in the group B compared with the preoperative value (p = 0.035). CHS was significantly decreased in all 3 ointment groups (p < 0.05) after general anesthesia and the degree was significantly higher in groups B and C (p < 0.001). No corneal abrasion developed after general anesthesia. However, corneal erosion developed in 20 eyes of previously healthy subjects; 8 eyes (12.5%) in group A, 0 eye (0%) in group B, 2 eyes (2.5%) in group C, and 10 eyes (13.9%) in group D. The occurrence rates of new lesions were significantly lower in groups B and C (p = 0.035). CONCLUSIONS: Both eyelid taping alone and eyelid taping with eye ointment are effective protection methods against corneal abrasion during operation under general anesthesia. Eye ointment instillation together with eyelid taping shows not only improvement of subjective symptoms but also improvement of objective ocular surface parameters proving to be an effective ocular protection during general anesthesia.

Wound healing of the skin and soft tissue defect is accomplished by generation of granulation tissue, collagen synthesis, contraction and re-epithelization. In the full-thickness skin wound, contraction plays an important role and fundamental principles in the treatment of infected wounds include the elimination of infection, the evacuation of pus, and the debridement of all necrotic material. The natural healing process of infected wounds can be expedited by the application of agents which will effectively eliminate infection with facilitating the healing process. Yunkyo is one of the most commonly used oriental herb medicine which is known to be effective in wound healing. In order to evaluate the effects of Yunkyo over wound healing and inhibition of bacterial growth, the author counted the bacterial colony in vitro and made skin defect on the back of rats for the comparison of reduced wound size and changes of tissue bacterial colony count after treatmnet with Solcoseryl, TCDO (Tetra-chloro-deca-oxide) and povidone. The results were obtained as follows: Calculating colony count in vitro, Yunkyo treated group was the most effective(p<0.001). There were significant differences between Yunkyo treated and control group in wound healing(p<0.001): Yunkyo healed the wound more rapidly. Calculating tissue bacterial colony count in open infected wound, Yunkyo treated group was showed the lowest colony count. In microscopic findings, the author observed marked growth of the granulation tissue, infiltration of the inflammatory cells, development of capillaries and even arrangement of collagen in Yunkyo treated groups than in the control group. In electron microscopy, abundant protein synthesis and myofilament in the myofibroblast were observed, and the authors found active wound contraction and the growth of granulation tissue. In conclusion, the Yunkyo has remarkable antibiotic effect and promotes wound contraction and the growth of granulation tissue in the process of wound healing.

In order to observe the growth, expansion and differentiation of the cultured bone marrow stromal cells (BMSC), we isolated the BMSC from adult SD rats and cultivated them with LIF and bFGF. Then, we cultured and induced the stem cells by using retinoic acid and the culture medium confected in our lab by ourselves. We found that the BMSC could expand and generate clones when they were cultured in vitro. These cells subcultured grew rapidly and differentiated into neuron-like cells and astrocyte-like cells. The results showed that BMSC have the abilities to self renew and differentiate, thus demonstrating the culture method we used is suitable for the culture of BMSC in vitro. The bone marrow stromal cell is not difficult to obtain; it is capable of expanding and differentiating in culture. If the culture condition is appropriate, it can differentiate into neuron and astrocyte. So, it is a kind of perfect seed cells.
