Sebaceous gland glands are in the areola that surrounds the nipple in the female breast. These glands secrete an oily fluid that lubricates the nipple, and also secrete volatile compounds that are thought to serve as an olfactory stimulus for the newborn. During pregnancy and lactation these glands, also called Montgomery's glands, become enlarged. Meibomian glands, in the eyelids, secrete a form of sebum called meibum onto the eye, that slows the evaporation of tears. It also serves to create an airtight seal when the eyes are closed and its lipid quality also prevents the eyelids from sticking together. The meibomian glands
Surgical sealant film Surgical sealant film A surgical sealant film is an implantable medical device used during surgery. It is a preformed flexible patch that is applied to supplement sutures and surgical staples to seal tissues and prevent leaks of fluid (including blood and cerebrospinal fluid) and air. The sealant film is synthetic and incorporates absorbable polymers, including poly(lactide-co-glycolide). The polymeric components impart structural and adhesive properties with the sealing effect achieved by incorporation of a bioadhesive polymer. This forms a covalent bond to primary amines present on the tissue surfaces. In turn this results in the film rapidly becoming effective in providing
