This study was designed to exam the aged's needs for spiritual nursing care. The purpose was to serve as a basis for the development of spiritual nursing practice. The major findings are as follows : 1. The degree of needs for spiritual nursing care as area was that needs of love and relationship mean 22.0, needs of meaning and object mean 28.2, needs of forgiving mean 13.5. Total needs for spiritual nursing care mean 63.7, which was on the upper middle level. The needs of meaning and object was rated highest. 2. Among the general characteristics of the subjects, needs of love and relatiohship wasn't significanlty different. 3. Among the general characteristics of the subjects, needs of meaning and object was significantly different according to two factors : age(F=7.260, p=0.001), religion(F=5.275, p=0.001). Higher needs of meaning and object was possessed by the older than the younger, by the one who have religion than the other. 4. Among the general characteristics of the subjects, four factors made a significantly difference to needs of forgiving : sex(t=-2.851, p=0.006), age(F=8.201, p=0.001), religion(F=6.928, p=0.000), disease(t=2.327, p=0.024). Higher needs of forgiving was possessed by man than woman, by the older than the younger, by the one who have religion than the other, by the one who have disease than the other.

To investigate radical scavenging effects and protective activities of bitter melon (Momordica charantia) against oxidative stress, in vitro and a cellular system using LLC-$PK_1$ renal epithelial cells were used in this study. The butanol (BuOH) fraction of bitter melon scavenged 63.4% and 87.1% of 1,1-diphenyl-2-picrylhydrazyl (DPPH) radicals at concentrations of 250 and $500{\mu}g/mL$, respectively. In addition, the BuOH fraction of bitter melon effectively scavenged hydroxyl radicals (${\cdot}OH$). At all concentrations tested, the scavenging activity of the BuOH fraction was more potent than that of the positive control, ascorbic acid. Furthermore, under the LLC-$PK_1$ cellular model, the cells showed a decline in viability and an increase in lipid peroxidation through oxidative stress induced by pyrogallol, a generator of superoxide anion ($O_2{^-}$). However, the BuOH fraction of bitter melon significantly and dose-dependently inhibited cytotoxicity. In addition, 3-morpholinosydnonimine (SIN-1), a generator of peroxynitrite ($ONOO^-$) formed by simultaneous releases of nitric oxide and $O_2{^-}$, caused cytotoxicity in the LLC-$PK_1$ cells while the BuOH fraction of bitter melon ameliorated oxidative damage induced by $ONOO^-$. These results indicate that BuOH fraction of bitter melon has protective activities against oxidative damage induced by free radicals.

As the use of preservatives in foods has been increased, the misuse and overuse of preservatives are occasionally occurred. As the variety of food has risen, it is necessary to establish the screening method to determine preservatives in various foods. In this study, benzoic acid, sorbic acid, methyl p-hydroxybenzoate, ethyl p-hydroxybenzoate, i-propyl p-hydroxybenzoate, n-butyl p-hydroxybenzoate were analyzed by TLC and HPLC. In order to determine the recoveries from food, these preservatives were spiked into foods. As a result, solvent systems of 8:2:0.45:0.05 and 12:2:0.45:0.05 of pentane:acetic acid:chloroform:ethanol were appropriate for TLC analysis of preservatives. All preservatives were well resolved with solvent system of 2% ammonium acetate in 2.5% acetic acid:methanol (90/10~10/90) by HPLC. Direct extraction of preservatives from food proved to be more proper than distillation and extraction method. The recoveries by direct extraction method showed 93.7~104.6% of preservatives studied.

To investigate radical scavenging effects and protective activities of bitter melon (Momordica charantia) against oxidative stress, in vitro and a cellular system using LLC-PK₁ renal epithelial cells were used in this study. The butanol (BuOH) fraction of bitter melon scavenged 63.4% and 87.1% of 1,1-diphenyl-2-picrylhydrazyl (DPPH) radicals at concentrations of 250 and 500 ㎍/mL, respectively. In addition, the BuOH fraction of bitter melon effectively scavenged hydroxyl radicals (ㆍOH). At all concentrations tested, the scavenging activity of the BuOH fraction was more potent than that of the positive control, ascorbic acid. Furthermore, under the LLC-PK₁ cellular model, the cells showed a decline in viability and an increase in lipid peroxidation through oxidative stress induced by pyrogallol, a generator of superoxide anion (O₂<sup>-</sup>). However, the BuOH fraction of bitter melon significantly and dose-dependently inhibited cytotoxicity. In addition, 3-morpholinosydnonimine (SIN-1), a generator of peroxynitrite (ONOO<sup>-</sup>) formed by simultaneous releases of nitric oxide and O₂<sup>-</sup>, caused cytotoxicity in the LLC-PK₁ cells while the BuOH fraction of bitter melon ameliorated oxidative damage induced by ONOO<sup>-</sup>. These results indicate that BuOH fraction of bitter melon has protective activities against oxidative damage induced by free radicals.
