단고추(Capsicum annum)는 중앙아메리카와 남아메리카의 열대지방이 원산지로 알려져 있고 매운맛이 없으며 미숙과를 주로 샐러드용으로 이용하는 원추형 과실을 착생하는 품종군으로 일반고추재배와는 달리 반드시 정지 및 유인을 해야만 좋은 과실을 생산할 수 있으며, 유인 및 관리정도에 따라 품질의 차이가 커 이것이 가격에 영향을 미쳐 농가의 소득과 직결되여 있다. 정지와 유인은 보통재배의 경우 U자형과 V자형으로 하고 있으나 노동력이 많이 소요된다. (중략)

The research on the manufacturing procedure of Hosanchun jun in the classical literature(17 kinds) showed that the most usually brewed rice wine in it is the 3rd step rice wine, which is brewed by adding rice wine base to it at the intervals used quantity are as follows. Nonglutinous rice(88.2%), flour(82.3%), and nu-ruk(100%) are used in the 1st step of brewing, and nonglutinous rice(82.3%), glutinous rice(17.6%), flour(23.5%), and nu-ruk(11.3%) are used in the 2nd sep, and glutinous rice, flour, and 3rd step of brewing. The grains are used in the form of -paste(88.2%) in the 1st, and in the form of paste(64.7%) and steamed water-soaked rice(sul-bab)(29.4%) in the second step, and sul-bab(64.7%) in the 3rd step of brewing. Nu-ruk is used in small quantity in the 3rd step but it is used I somewhat larger quantity in the 2nd step of brewing.

Recombinant interleukin-2(IL-2) has demonstrated as an antineoplastic agent in mice and human, but the relatively low response rates observed in clinical trials. Therefore, the present study was undertaken in order to evaluate therapeutic activities of IL-2 for the establishment of therapeutic applications. At the onset of the experiment, normal C3H/HeN mice were injected with 5$\times$10$\^$6/ RD-995 tumor cells, murine ultraviolet radiation-induced fibrosarcoma, intraperitoneally. Beginning on day 6, experimental groups were treated with a 5-day course of IL-2(subcutaneous injection of 30,000 IU every 12 hours for 5 days). The result of this experiment revealed that body weight gradually decreased from 20th day in control mice. Subcutaneous IL-2 therapy prevented partially decrease body weight, and prolonged survival of mice compared with control group.

Tremor is a rhythmic and involuntary muscular contraction charaterized by oscillations of body parts. tremor often accompanies neurological disorders associated with aging. Although the disorder is not life-threatening, it can be responsible for functional disability and interpersonal relationship problems. We have recently examined a number of tremor-patients. One of them was improved significantly through the herbal medicine (Ssanghaptang-gamibang) and accupuncture, so we report it for the better treatment.

We used an amplified fragment length polymorphism (AFLP) analysis, a novel PCR-based technique, to differentiate Xanthomonas oryzae pv. oryzae (Xoo) of Korean races. The 6 strains of Xoo K1, K2, K3 races were tested with 81 AFLP primer combinations to identify the best selective primers. The primer combinations were selected according to their reproducibility, number of polymorphic bands and polymorphism detected among Xoo strains. 18 strains of Xoo K1, K2 and K3 races were analyzed with the selected combinations of primer set. Some primer combinations (Eco R I +1 / Mse I+1) could differentiate Xoo of Korean races that were not distinguished by other fingerprinting analysis. Thus AFLP fingerprinting permitted very fine discrimination among different races.

An experiment was conducted to study the effect of soluble protein supplements on concentration of soluble non-ammonia nitrogen (SNAN) in the liquid phase of ruminal (RD) and omasal digesta (OD) of Korean native steers, and to investigate diurnal pattern in SNAN concentration in RD and OD. Three ruminally cannulated Korean native steers in a $3{\times}3$ Latin square design consumed a basal diet of rice straw and corn-based concentrate (control), and that supplemented (kg/d DM basis) with intact casein (0.24; IC) or acid hydrolyzed casein (0.46; AHC). Ruminal digesta was sampled using a vacuum pump, whereas OD was collected using an omasal sampling system at 2.0 h intervals after a morning feeding. The SNAN fractions (free amino acid (AA), peptide and soluble protein) in RD and OD were assessed using the ninhydrin assay. Concentrations of free AA and total SNAN in RD were significantly (p<0.05) lower than those in OD. Although free AA concentration was relatively high, mean peptide was quantitatively the most important fraction of total SNAN in both RD and OD, indicating that degradation of peptide to AA rather than hydrolysis of soluble protein to peptide or deamination may be the most limiting step in rumen proteolysis of Korean native steers. Diurnal variation in peptide concentration in OD for the soluble protein supplemented diets during the feeding cycle peaked 2 h post-feeding and decreased thereafter whereas that for the control was relatively constant during the entire feeding cycle. Diurnal variation in peptide concentration was rather similar between RD and OD.

Aims: To study the CIK cell treatment effects on regulation of cellular immune function disorders in patients with lung cancer, and to analyze the time characteristics. Methods: Cellular immune function was assessed by FCM, and patients with functional disorders were randomly divided into two groups, one given CIK cell therapy within 18 months (5 courses) and the other the controls, which were followed up for 1 year with cellular immune functions tested once a month. Results: There were 5 types of cellular immunity, 4 of which are disorders; after CIK treatment, the improvement rate of the 4 groups were 79.1%, 70.8%, 76.0% and 70.0%, intergroup differences not being statistically significant (P=0.675), all significantly higher than in the control group (P=0.000). The median maintenance times for the 4 groups were 10.4 months (9.76-11.04), 8.4 months (7.86-8.94), 9.8 months (9.20-10.4) and 7.9 months (6.25-9.55), respectively. Conclusions: CIK cells were able to improve the immune functions of patients with lung cancer, the rate of improvement and maintenance time being related to the immune function before the treatment and CIK-cell-therapy courses.

Purpose: Breastfeeding is the best way to feed all infants, but not all infants can be (exclusively) breastfed. Cow's milk based infant formula is the second choice infant feeding. Methods: The safety of a new synbiotic infant formula, supplemented with Bifidobacterium lactis and fructo-oligosaccharides, with lactose and a whey/casein 60/40 protein ratio was tested in 280 infants during 3 months. Results: The median age of the infants at inclusion was 0.89 months. Weight evolution was in accordance with the World Health Organization growth charts for exclusive breastfed infants. The evolution of all anthropometric parameters (weight-for-length z score and body mass index-for-age z score) was within the normal range. The incidence of functional constipation (3.2%), daily regurgitation (10.9%), infantile crying and colic (10.5%) were all significantly lower than the reported median prevalence for a similar age according to literature (median value of 7.8% for functional constipation, 26.7% for regurgitation, 17.7% for infantile colic). Conclusion: The new synbiotic infant starter formula was safe, resulted in normal growth and was well tolerated. Functional gastro-intestinal manifestations (functional constipation, regurgitation and colic) were significantly lower than reported in literature. Synbiotics (Bifidobacterium lactis and fructo-oligosaccharides) in cow's milk based infant formula bring the second choice infant feeding, formula, closer to the golden standard, exclusive breastfeeding.

The purpose of this study is the identification of (N-2-hydroxy-3-butenyl) valine(HBVal adduct) and (N-2,3,4-trihydroxy-butyl)valine(THBVal adduct)with mice inhalation exposure with 1,3-butadiene for 3 weeks($6\;hr/day\;{\times}\;5\;days/week$). Body weights were significantly lower from 4 or 9 exposure post-day in 1000 or 500ppm inhalation group than in control. The levels of HBVal adducts are 1.8, 3.7 and 6.2 pmol/mg globin in $1^{st}$, $2^{nd}$ , and $3^{rd}$ week for 500 ppm 1,3-butadiene(BD), and 5.7, 7.4 and 16.0 pmol/mg globin in $1^{st}$, $2^{nd}$ , and $3^{rd}$ week for 1000 ppm BD inhalation exposure. The levels of THBVal adducts are 32.0, 42.0 and 55.0 pmol/mg globin in $1^{st}$, $2^{nd}$ , and $3^{rd}$ week for 500 ppm BD, and 67.8, 72.7 and 83.5 pmol/mg globin in $1^{st}$, $2^{nd}$ , and $3^{rd}$ week for 1000 ppm BD inhalation exposure. Their ratios of THBVal and HBVal adducts are higher at earlier exposure and lower concentration. They are17.8, 11.4 and 8.87 in $1^{st}$, $2^{nd}$ , and $3^{rd}$ week for 500 ppm BD, and 11.9, 9.8 and 5.2 in $1^{st}$, $2^{nd}$ , and $3^{rd}$ week for 1000 ppm BD inhalation exposure. In conclusion, THBVal and HBVal adducts are a important hemoglobin adduct for monitoring of BD exposure, and the latter is more biomarker than the other.
