The longitudinal changes on human milk volume per day and lactational performance of 23 Korean lacto-ovo-vegetarians(primiparae=11, multiparae=12) from 0.5 to 5 months after parturition have been studied by test weighing method. The human milk volume per day tended to increase during lactation. The mean volume (SD, ml/day) at 0.5, 1, 2, 3, 4, 5 months were 502(102), 692(127), 697(100), 684( 125), 757(52), 703(70), respectively. The overall mean volume was 661$\pm$132ml/day. The peak milk volume during the lactation was observed at most lactating women at the 1st month. The distributions of the individual mean volume during the first 5 months of lactation were found over 750m1(8.7% ), 650-750ml(47.9% ), 550-650m1(2l.7% ), and 450-550ml(2l.7% ) The number of feeding per day was 8.1 ($\pm$1.0) at 0.5 months postpartum, which was consistently decreased. However, the mean volume per feeding was increased from 62($\pm$9.5)ml at 0.5 month to 112($\pm$13.3)ml at 5 months postpartum. The milk volume was correlated with the peak volume. and maternal age. but not with weight before delivery. maternal height and birth weight. No differences of milk volume and lactational performance between facto-ovo-vegetarian and nonvegetarian women were observed. This study suggests that the human milk volume cited in the recommended dietary allowances for Koreitns is over estimated.

In the present study, we have evaluated cytotoxic effects of Taraxaci Herba extract in human oral epitheloid carcinoma cells. An antitumor activity was measured by colorimetric assays using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-2H-tetrazolium bromide (MTT) and sulforhodamine protein B (SRB). The light microscopic study showed morphological changes, Ag-NOR (argyrophylic nucleolar organizer region) number and PAS positive reaction or the treated cells. These results obtained are as follows : MTT and SRB quantities were significantly decreased in cultured KB cells treated with 10$^{-2}$ /mg/ml and 10$^{-3}$ /mg/ml concentrations. The number of Ag-NORs were significantly decreased in cultured KB cells treated with 10$^{-2}$ /mg/ml and 10$^{-3}$ /mg/ml concentrations and the rate of Ag-NORs was shifted to left side (one Ag-Nounucleus was increased and five Ag-NORs/nucleus were decreased) by the high concentration. PAS reaction of cultured KB cells treated with 10$^{-2}$ /mg/ml and 10$^{-3}$ /mg/ml concentrations was negative. These results suggest that Taraxaci Herba retains a potential antitumor activity.

The optimal temperature, pH and aeration rate for spore production by Bacillus polyfermenticus SCD in 500 ml shake flask and 5-1 jar fermenter were found to be $32^{\circ}C$, 7.0 and 1.0 vvm. respectively. When batch culture processes was performed under optimized culture conditions. viable cells were $3.3{\times}10^{10}$ CFU/ml and spore cells were $3.3{\times}10^{10}$ CFU/ml. Fed-batch culture processes were also examined with regard to higer maximum viable cell and spore production. The highe viable cells and spores were obtained in 5-1 jar fermenter at 72 h cultivation time by strategy in an intermediate feeding mode with 60% glucose solution 150 ml and 5% soybean flour solution 150 ml fed to the fermenter twice, and the productivity of spore cells was significantly increased. Finally. volumetric productivity of spore cells on fed-batch culture indicated $9.9{\times}10^8$ CFU/ml/h, which was approximately 2 times higher than batch culture. Thus, fed-batch culture show a promise as an industrial production method.

Background: The present study was undertaken to establish any correlation of elevated levels of CA19-9 with tumor stage or grade of urothelial carcinoma. Materials and Methods: This hospital based study was carried out in the Department of Biochemistry of Nepalese Army Institute of Health Sciences between $1^{st}$ July 2012 and $31^{st}$ December 2012. Approval for the study was obtained from the institutional research ethical committee. CA19-9 was assayed with an ELISA reader for all cases and expressed in U/ml with 37U/ml taken as the cut-off upper value for normal. Results: Out of 20 cases enrolled, 15 were of urothelial carcinoma and the remaining 5 were controls. There was marked difference between the mean values of CA19-9 in cases $40.2{\pm}19.3U/ml$ of urothelial carcinoma and controls $7.98{\pm}7.34U/ml$. The number of cases in Ta, TI, T2, T3, T4 stages of urothelial carcinoma were 2, 6, 3, 3, 1 respectively. The percentage rise in CA19-9 was less with low grade tumors (22.2%) when compared with high grade tumors (66.6%) (p value $0.001^*$). The percentage of rise in CA19-9 for muscle invasive tumors was very high when compared to superficial tumors. Similarly, the percentage of rise in CA19-9 for metastatic disease was very high when compared to non-metastatic disease and it was found statistically significant (p value $0.001^*$). Conclusion: Serum CA19-9 levels predicts the prognosis of urothelial carcinoma as it is almost invariably raised in tumors having metastatic spread.

Follicular flxid (FF) and their matched oocytes were obtained from 58 follicles of 27 women who underwent an in vitro fertilization (IVF) procedure with ovarian hyperstimulation by clomiphene citrate(n=8), hMG(n=9),FSH/hMG(n=10). Follicular aspiration was performed 36 hours after human chorionic gonadotropin administration. The concentcation of androstendione (ADD), testosterone (T) was correlated with hyperstimulation regimens, the morphology of the oocyte-corona-cumulus complex (OCCC), oocyte fertilization, and the incidence of pregnancy after embryo transfer. The results were as follows. 1. According to hyperstimulation regimens, there was no significant differance in FF ADD and T concentrations of the similar morphology of OCCC. 2. In clomiphene-treated and FSH/hMG-treated cycles, FF ADD concentrations of preovulatory oocytes were 43.09${\pm}$9.53 ng/ml and 59.46${\pm}$9.09 ng/ml, those of immature occytes were 96.98${\pm}$16.55 ng/ml and 116.13${\pm}$36.81 ng/ml, those of atretic oocytes were 246.5 ${\pm}$9.25 ng/ml and 634.25${\pm}$9.25 ng/ml respectively, reflecting the significant relationship between FF ADD level and morphologic maturity of OCCC (p<0.05). But in hMG-treated cycles, such relationship was not found (p>0.1). In clomiphene-treated and FSH/hMG-treated cycles, FF T concentrations of preovulatory oocytes were 11.37${\pm}$2.38 ng/ml and 11.68${\pm}$1.73 ng/ml respectively which were significantly lower than those of atretic oocytes (25.1${\pm}$7.50 ng/ml and 23.25${\pm}$0.95 ng/ml respectively) (p<0.05). But in all cycles, FF T concentrations of immature oocytes were not significantly different from those of preovulatory oocytes, artetic oocytes (p>0.1). 3. In hMG-treated and FSH/hMG-treated cycles, FF ADD concentrations of fertilized oocytes were 32.43${\pm}$4.09 ng/ml and 42.61${\pm}$4.82 ng/ml respectively which were significantly lower than those of non-fertilized oocytes (72.18${\pm}$17.31 ng/ml and 108.09${\pm}$17.32 ng/ml respectively) (p<0.05), but in clomiphene-treated cycles there was no significant difference (p>0.1). In FSH/hMG-treated cycles, FF T concentration of fertilized oocytes was 7.33${\pm}$1.06 ng/ml which was significantly lower than that of non-fertilized oocytes (20.3${\pm}$6.21 ng/ml) (p>0.02), but in clomiphne-treated and hMG-treated cycles there was no significant difference (p>0.1). 4. In all cycles FF ADD and T concentrations did not correlated with the success of pregnancy after embryo transfer. Above results suggested that FF ADD and T may play an important role in oocyte maturation and fertilization, but their relationship with the success of psegnancy was not found.
