The bioequivalence of two cyclosporine A (CyA) 100 mg soft capsules (Chong Kun Dang's $Cipol-N^{(R)}$ as the test drug; Korea Novartis' Sandimmun $Neoral^{(R)}$ as the reference drug) was assessed in healthy male Korean volunteers after oral administration of 200 mg CyA according to a randomized crossover design. The whole blood samples were analyzed for the determination of parent CyA in the blood by using a validated HPLC/diode array detector method. The mean $AUC_t$ values for reference and test products were $4095.3{\pm}1397.2$ and $3958.3{\pm}1138.2\;ng{\cdot}hr/mL$, respectively. The mean $C_{max}$ values were $1135.9{\pm}293.2\;ng/mL$ for the reference product, and $985.0{\pm}207.9\;ng/mL$ for the test product. $T_{max}$ was $1.6{\pm}0.4\;hr$ for the reference and $1.8{\pm}0.5\;hr$ for the test product. The differences of $AUC_t$, $C_{max}$ and $T_{max}$ were -3.35, -13.28 and +10.63%, respectively. The point estimates and 90% confidence intervals for $AUC_t$ and $C_{max}$ were 0.981 (0.9171 to 1.0514) and 0.876 (0.8229 to 0.9336), respectively. Based on the pharmacokinetic and statistical data, we conclude that these two products are bioequivalent and can be considered interchangeable in the medical practice.

The milk product is one of the major foods which provide calcium for nutritional requirement. In addition to calcium, it supplies diverse nutrients including protein, potassium, vitamin A, vitamin $B_1$, and vitamin $B_2$. Adequate calcium intake throughout lifetime ensures optimum bone density and prevents osteoporosis in old age by reducing loss of bone mineral during growth and aging. The nutritional deficiency of calcium intake and spreading of osteoporosis in Korean population accentuated necessity of adequate calcium intake through milk consumption. Obstruction of milk consumption due to lactose intolerance should be overcome by educational programs for adequate milk consumption and low-lactose milk product developments. Consumption of milk products was reported to prevent high blood pressure in clinical studies and epidemiological investigations. As the feeding of milk increased, the body weight and fat of animal decreased in animal studies. The epidemiological investigations revealed that there was a negative correlation between the amount of milk consumption and the body fat. When calcium was provided as dietary supplement in the clinical trials, the body weight and body fat of subjects decreased. When calcium was particularly supplied as a part of milk, the body weight reduction rate was augmented. Calcium, vitamin D, and conjugated linoleic acid have been reported to exert a role in reducing cancer. The paramount importance of milk in nutrition as a source of calcium and other invaluable nutrients emphasizes consistent supply of milk products to adults as well as adolescents by dairy industry.

The purpose of this study was to examnin the effect of slow stroke back massage(SSBM) on anxiety and immune response in patients undergoing open heart surgery and to compare the effect of 5-minutes with 10-minutes SSBM. Among the sixty-four patient subjects, twenty-one were one experimental group receiving massage for 10-minutes, twenty for the other experimental group receiving massage for 5-minutes and twenty-three for the control group. Subjects were admitted at Hospitals in Inchon and Puchon for open heart surgery. This study was carried out from October 10, 1997 to May 10, 1998. The levels of anxiety were measured by the Visual Analogue Scale(VAS), Trait anxiety scale, systolic and diastolic blood pressure, pulse rate, blood cortisol and the levels of immune response were measured by the blood T-lymphocyte and Natural killer cell. Study measurements were taken before and after SSBM on the 1st post operative day. Data were analyzed using x$^2$ test, oneway ANOVA, paired t-test, t-test and Pearson product moment correlation. The results were summarized as follows : 1. After SSBM, VAS anxiety level, systolic and diastolic blood pressure and pulse rate of the experimental group were decreased significantly than those measurements before the SSBM. After SSBM, significant difference in the VAS anxiety level, systolic blood pressure and pulse rate between the experimental and control groups were found. 2. After SSBM, the blood cortisol of the experimental and control groups were increased significantly compared with before SSBM. But the significant difference in blood cortisol between the two groups was not found. 3. After SSBM, the blood T-lymphocyte percentages of the experimental and control groups were decreased signigicantly and blood Natural killer cell percentages of the two groups were increased compared with before SSBM. But significant difference in blood T-lymphocyte and Natural killer cell percentages between the two groups was not found. 4. Significant difference in VAS anxiety level, systolic and diastolic blood pressure, pulse rate, blood cortisol, blood T-lymphocyte and Natural killer cell percentages between SSBM for 5 minutes and SSBM for 10 minutes were not found. Based upon the results, this study concludes that the slow stroke back massage for 5 minutes is a useful intervention that decreases anxiety and produces relaxation in patients undergoing open heart surgery.

We have investigated the effect of MeOH extract of the adventious root culture of Panax ginseng on hyperlipidemic rats induced by fat-rich diet. We also analyzed and compared the content ginsenoisdes of the cultured ginsengs by HPLC. After oral administration of the MeOH extract to hyperlipidemic rats for four weeks, the variables including body weight, cholesterol, HDL, LDL, and triglyceride levels in serum were measured. One of the cultured ginseng roots (CBN3) decreased cholesterol and LDL-cholesterol and increased HDL-cholesterol levels in serum. HPLC analysis demonstrated that CBN3 contains more $Rb_1$ and Rd ginsenosides than any other cultured ginsengs and cultivated ginseng. These results suggest that CBN3 with high contents of $Rb_1$ and Rd may be useful in lowering blood cholesterol.

In this experiment, three kinds of autoclaved poultry by-product meals, P1 (head+feet+viscera), P2(P1+blood), and P3(P2+feathers), mixed as to the yielding ratios, and three kinds of autoclaved hatchery by-products meals, H1 (male d-old chicks of egg strain), H2(dead embryos ＆ infertile eggs), and H3(H1+H2, 2:1) were formulated into the layer diets each at 5％ level, respectively, and compared with the control diets(C) containing fishmeal on laying performances and egg qualifies. The egg production, average egg weight, feed intake and feed conversion were not significantly affected by the poultry or hatchery by-product meals. The egg shell qualities, such as the egg specific gravity, egg breaking strength and shell thickness, were not different among treatments. The egg yolk colour was improved by the feeding of hatchery by-products meals (P<0.05). In conclusion, pultry and hatchery by-product meals could be used in layer diets without any adverse effects on laying performances to substitute for fishmeal at about 5％ level.

Saururus chinensis Baill was reported to inhibit ${\alpha}-glucosidase$ in vitro and flatten postprandial increase in blood glucose in streptozotocin (STZ)-induced diabetic rats. We studied the effect of chronic consumption of S. chinensis Baill on blood glucose and lipid profile in STZ-induced diabetic male rats fed high fat diet. Male rats weighing 100-120 g were fed 30% fat diet with and without 10% freeze-dried leaves of S. chinensis Baill for 7 weeks after 1 week of adaptation. The rats were rendered diabetic by intravenous injection of STZ (60 mg/kg) after 6-week feeding of the assigned diets. At 1 week after the injection, the rats were sacrificed after an overnight fast. Plasma glucose ($380.2{\pm}14.4mg/dL$), total cholesterol ($93.9{\pm}7.9mg/dL$) and triglyceride levels ($123.6{\pm}7.5mg/dL$) of the S. chinensis Baill group were significantly lower than those of the control group ($418.1{\pm}12.0mg/dL,\;119.9{\pm}9.4mg/dL,\;152.0{\pm}10.3mg/dL$, respectively, p<0.05). Chronic consumption of S. chinesis Baill significantly decreased maltase activity of the small intestinal mucosa ($120.1{\pm}8.7U/g$) protein compared with the control group ($96.8{\pm}7.0U/g protein, p<0.05). These results suggest that S. chinensis Baill have hypoglycemic and hypolipidemic effects by inhibiting ${\alpha}-glucosidase$ activity in the animal model of diabetes mellitus.

In summary, progesterone is probably the only naturallly occurring progestational agent of any significance. Small amounts may be synthesized by the cells of the follicle in the provulatory swelling phase; however, the major production is by the corpus luteum cells of the ovary during the luteal phase of the cycle. It is constantly produced in small amounts by the adrenal gland and by the testis in the male. In the adrenal and the testis, it probably serves as the precursor for corticoids and androgens. It is transported in the blood by a specific binding protein and metabolized and conjugated in the liver into sodium pregnanediol glucuronide which also circulates in the blood. Approximately 20% is excreted in the urine as sodium pregnanediol glucronide; pregnanolone represents a minor metabolic product. The pregnanediol which is excreted in the bile is enzymically hydrolyzed by the gut so that the pregnanediol recovered in the feces is in the free form.

Pharmacognostic study was carried out on the seeds of Trigonella foenumgraecum L. (fenugreek) in order to establish its pharmacognostic characteristics. In view of its renewed interest as a dietary supplement among the local inhabitants afflicted with diabetes, its hypoglycaemic activity in normal as well as diabetic rats was also investigated. Oral glucose tolerance test showed that a suspension of the powdered trigonella seed inhibited the increase in blood glucose levels in normal rats that had been treated with an oral glucose load prior to the test. A reduction in the blood glucose levels was also observed when a suspension of the powdered seed was given by gastric intubation to the streptozotocin-induced diabetic rats. These findings suggested that trigonella seeds possessed some hypoglycaemic activities that might be useful to the diabetics.
