Sparassis (S.) crispa is an edible mushroom abundant in dietary fiber and ${\beta}$-glucan. The aim of this study was to prepare extracts and residues of the fruit bodies of S. crispa fermented with Lactobacillus (L.) brevis and Monascus (M.) pilosus and to measure the remaining dietary fiber and ${\beta}$-glucan. Dried powder of S. crispa containing 64.4 g/100 g total dietary fiber (2.6 g/100 g soluble and 61.8 g/100 g insoluble dietary fibers) and 24.0 g/100 g ${\beta}$-glucan was used as the starting material for the extraction. Raw and fermented S. crispa were extracted with hot water and three kinds of aqueous ethanol (50, 70, and 90%, v/v), respectively. A hot water extract from S. crispa fermented with M. pilosus had greater soluble dietary fiber content (19.3 g/100 g) than that from raw S. crispa with 14.6 g/100 g soluble dietary fiber or that from L. brevis-fermented S. crispa with 8.2 g/100 g soluble dietary fiber. The yield of the extract was 16.6% of intial weight of dried S. crispa. After hot water extraction of S. crispa fermented with M. pilosus, residues containing 90.5 g/100 g total dietary fiber (1.3 g/100 g soluble and 89.2 g/100 g insoluble dietary fibers) were obtained, and the yield was 69.6% of intial weight of dried S. crispa. The residue (31.0 g/100 g) contained more ${\beta}$-glucan than raw S. crispa or M. pilosus-fermented S. crispa (24.4 g/100 g). The resulting hot water extract and residue from S. crispa fermented with M. pilosus would be suitable for use in preparing liquid and powdered health functional foods, respectively.

Calcium ions play an important role in the establishment and maintenance of pregnancy, but molecular and cellular regulatory mechanisms of calcium ion action in the uterine endometrium are not fully understood in pigs. Previously, we have shown that calcium regulatory molecules, transient receptor potential vanilloid type 5 (TRPV6) and calbindin-D9k (S100G), are expressed in the uterine endometrium during the estrous cycle and pregnancy in a pregnancy status- and stage-specific manner, and that estrogen of conceptus origin increases endometrial TRPV6 expression. However, regulation of S100G expression in the uterine endometrium and conceptus expression of S100G has been not determined during early pregnancy. Thus, we investigated regulation of S100G expression by estrogen and interleukin-$1{\beta}$ (IL1B) in the uterine endometrium and conceptus expression of S100G during early pregnancy in pigs. We obtained uterine endometrial tissues from day (D) 12 of the estrous cycle and treated with combinations of steroid hormones, estradiol-$17{\beta}$ ($E_2$) and progesterone ($P_4$), and increasing doses of IL1B. Real-time RT-PCR analysis showed that $E_2$ and IL1B increased S100G mRNA levels in the uterine endometrium, and conceptuses expressed S100G mRNA during early pregnancy, as determined by RT-PCR analysis. To determine if endometrial expression of S100G mRNA during the implantation period was affected by the somatic cell nuclear transfer (SCNT) procedure, we compared S100G mRNA levels in the uterine endometrium from gilts with SCNT-derived conceptuses with those from gilts with conceptuses derived from natural mating on D12 of pregnancy. Real-time RT-PCR analysis showed that levels of S100G mRNA in the uterine endometrium from gilts carrying SCNT-derived conceptuses was significantly lower than those from gilts carrying conceptuses derived from natural mating. These results showed that S100G expression in the uterine endometrium was regulated by estrogen and IL1B of conceptus origin, and affected by the SCNT procedure during early pregnancy. These suggest that conceptus signals regulate S100G, an intracellular calcium transport protein, for the establishment of pregnancy in pigs.

In this study, the quality characteristics of the representative domestic garlic varieties in Korea (Namdo, Daeseo, Hongsan, and Uiseong garlic) were compared and their changes according to the aging process of black garlic were investigated. Each garlic sample was aged for 15 days according to the manufacturing process of black garlic. The total phenolic compound contents were 85.2-109.7 mg GAE/100 g in raw garlic samples, which increased with the aging period, and Hongsan garlic showed the highest content in both raw and aged black garlic. The content of alliin was 848.3-1,087.5 mg/100 g in raw garlic samples, and it decreased significantly on the 5th day (7.3-20.6 mg/100 g) in aged garlic. The contents of GSAC (γ-glutamyl-S-allyl-cysteine) and GS1PC (γ-glutamyl-S-1-propenyl-l-cysteine) in raw garlic samples were 202.1-541.0 mg/100 g and 311.1-474.3 mg/100 g, respectively, but gradually decreased during the aging process. On the other hand, the SAC (S-allyl-cysteine) and S1PC (S-1-propenyll-cysteine) contents of raw garlic were very low in all four varieties, but they were highest on the 5th day of aging and tended to decrease thereafter. On the 5th day of aging, the SAC content of Namdo garlic (208.0 mg/100 g) was highest (p<0.05), and S1PC content was significantly higher in Uiseong garlic (66.2 mg/100 g) than the others.

Vegetables are rich sources of dietary fiber, which exhibit various health benefits. In the Republic of Korea, vegetables are consumed after cooking using different methods. However, they are most commonly eaten raw or blanched. In this study, chamnamul, sesame leaf, Fischer's ragwort, burdock root, and garlic stem from Korea were analyzed according to the Korean Food Code, and changes in dietary fiber content after blanching were compared. Blanching reduced the total dietary fiber (TDF) content in chamnamul (from 3.67±0.03 to 2.61±0.14 g/100 g), burdock root (from 4.95±0.40 to 3.89±0.10 g/100 g), and sesame leaf (from 4.32±0.12 to 3.65±0.17 g/100 g), but increased it in Fischer's ragwort (from 6.09±0.49 to 6.43±0.01 g/100 g) and garlic stem (from 4.52±0.35 to 5.09±0.04 g/100 g). Sucrose, glucose, and fructose were detected in the vegetables; however, sesame leaf did not have sucrose. Fresh burdock root had the highest sucrose content (1.71±0.07 g/100 g) whereas garlic stem had the highest glucose and fructose content (1.65±0.02 and 1.73±0.02 g/100 g, respectively) compared with other vegetables. Upon blanching, the free sugar content of vegetables decreased for all sugars except for sucrose, which increased in Fischer's ragwort (from 0.10±0.01 to 0.14±0.01 g/100 g) and garlic stem (from 0.76±0.00 to 0.83±0.01 g/100 g). These results can provide information on blanching-associated changes in the content of dietary fiber and free sugar in foods prepared using these vegetables.
