The extensibility of the albino rabbit sclera was measured after cryoapplication and diathermy on the equator of sclera and these extensibilities were compared with normal control. For cryoapplication, 95% alcohol and solid carbon dioxide mixture was used and this cryoprobe was applied on the equator of rabbit sclera of right eye for 3 seconds. Castroviejo apparatus was used for diathermy and nonperforating surface diathermy was performed on the equator of rabbit sclera of left eye for one second with current of 30mA. Immediately after cryoapplication and diathermy, the extension rates of sclera were 2.556% and 6.039%, respectively. The extension rates of one week after cryoapplication and diathermy were 3.234 % and 4.127%, respectively. The extension rate of two weeks after diathermy was 3.489%. Normal control was 3.055%.

Traditional medical device sterilization processes are mature, but there are constraints when using on medical devices by new materials. With increasing environmental concerns, using of ethylene oxide sterilization has been limited by global environmental protection administrations. Exploring new sterilization methods for medical devices is urgently needed. This paper reviews the supercritical carbon dioxide sterilization technology by arranging the exploratory work of industry researchers. In the paper, we introduce the theory of supercritical carbon dioxide sterilization technology, microbial inactivation ability, material influence research and sterilization equipment. Then we discuss the concerns and possibilities of the technology applied to the medical device industry basing on the good manufacturing practices.

Carbon dioxide (CO2) poisoning is rare, but its clinical features of acute exposure include cardiovascular, respiratory, neurologic and metabolic aspects. CO2 can also have a direct toxicological effect. At very high concentrations (>9%), CO2 induces respiratory depression and narcotic-like effects on the central nervous system. Especially, acute poisoning from dry ice is caused by CO2 gas inhalation and asphyxiation, and may impose excess load on the myocardium. This case was an acute CO2 poisoning from dry ice gas inhalation. In spite of an initial severe status, the male patient rapidly improved with no complications following the application of highly concentrated oxygen and fluid therapy.

14 patients with xanthelasma palperbraum of the eyelids have been treated with the CO2 laser. The lipomatous yellow plaque are accurately photovaporized in a bloodless field until the lesion is totally eradicated. The operation with the CO2 laser does not depend on a shape, size, position of the lesion. Satisfactory cosmetic results were achived in 13 of 14 patients without significant scarring.
