Lactose is a disaccharide consisting of a glucose and a galactose. Milk is a sole source of lactose in natural food. Lactase hydrolyzes lactose into glucose and galactose, which are absorbed in the intestine and utilized by the body. After weaning, lactase activity declines. Therefore, the majority of adults have hypolactasia. The prevalence is above 50% in South America, Africa, and Asia. A significant amount of lactose is consumed as cow milk-based food products. However, it has no special nutritional importance for adults, and it is suspected as a dietary risk factor for coronary heart disease (CHD) and ovarian cancer. The aim of this study is to review the evidence and to propose possible mechanisms regarding the relations between lactose intake and CHD and ovarian cancer. Epidemiological studies support the connection of lactose and CHD. Although several mechanisms for elucidation of this connection have been suggested, calcium theory is the most plausible. Galactose is known to be toxic to ovary. Galactose has been suggested to induce ovarian cancer through hypergonadotropic hypogonadism. Some epidemiological data support this but others do not. Consumption of lactose or galactose can induce CHD and ovarian cancer; however, more research will be needed in order to determine the relation between lactose and these diseases.

A new cultivar of Phalaenopsis, "Snow Dream" was initially selected from the progenies of the cross of Phal.3016xPhal.3021 (no name, collection at the nursery) in 1996 at the National Horticultural Research Institute, Rural Development Administration. Final selection was made in 2003 after the investigation of the characteristics for five years (1999-2003). "Snow Dream" has long blooming (about 4months), white flower, pink stripe lip, semi-upright leaf. PLB(Protocorm Like Body) induction rate was 70%. The width of flower is 9.0 cm. The direct sun light should be avoided for its appropriate growth. Growing temperatures should not be exceed 35℃/15℃ (day/night). A variety protection for "Snow Dream" has been applied in 2005.

A new cultivar of Phalaenopsis, "Orange Dream" was initially selected from the progenies derived from self-pollination of 3091(no name) in 1996 at the National Horticultural Research Institute, Rural Development Administration. It was finally selected in 2003 after the investigation of the characteristics for five years (1999-2003). "Orange Dream" has orange color and purple line with thick petal, sepal, and long blooming, semi-upright leaf and high-mass propagation of 70%. The width of flower is 6.5 cm with medium sized and the number of flowers is 6. Strong sunlight should be avoided for its growth. Growing temperatures of 35℃/15℃(day/night) are advisable. A variety protection has been applied for this cultivar in 2005.
