This study examined the effects of dietary processed pine needle tree powder (PPNP) on growth performance, visceral organ parameters, ileal digestibility, blood metabolites and ileal morphology of broiler chickens for 5-week after hatch. In total, 220 1-day-old male Ross 308 broiler chicks were randomly allocated to 30 pens (seven birds per pen), and each pen was assigned to one of five dietary treatments, a diet without PPNP (control) and diets with 0.5%, 1.0%, 1.5% and 2.0% PPNP. The body weight and feed intake were measured weekly. One bird from each pen was selected randomly and gently euthanized to collect the blood, visceral organs and digesta samples on 2, 3 and 5 week of age. Birds fed 2.0% PPNP showed decreased (P<0.05) overall body weight, average daily gain and average daily feed intake compared to those fed control, 0.5 and 1.0% PPNP. The small intestine length increased (P<0.05) as the level of PPNP in the diet increased. A deeper crypt depth was observed (P<0.05) when birds fed 2.0% PPNP compared to those fed the control diet at week 2. A higher V:C ratio was observed (P<0.05) in birds fed 1.0% PPNP than in those fed other treatments at week 3. Ileal protein digestibility improved (P<0.05) when birds fed 0.5% and 1.0% PPNP compared to that in those fed the control diet at week 3. The feed conversion ratio, ileal dry matter digestibility and blood urea nitrogen and cholesterol, and gizzard and ceca weights were not affected (P>0.05) by supplementation of any levels of PPNP. These results demonstrated that inclusion of PPNP in broiler diets could be a possible factor in improving overall growth performance suggesting early gut development when 1% PPNP is supplemented.
A 1 : 1 mixture of acriflavine (ACF; CAS 8063-24-9) and guanosine is currently being evaluated as a possible antitumor agent in preclinical studies. Guanosine is known to potentiate the anticancer activity of some compounds. However, the distributions of trypaflavine (TRF) or proflavine (PRF) have not been investigated in mammals. We, therefore, investigated the distribution of TRF and PRF after i.m. administration of the combination mixture (ACF and guanosine) at a dose of 30 mg/kg ACF in rats. to analyze TRF and PRF levels in biological samples, we used an HPLC-based method. The calibration curves for TRF and PRF in the samples were linear over the concenration range of $0.05{\sim}200\;{\mu}g/ml$. The intra- and inter-day assay accuracies of this method were within ${\pm}15\%$ of norminal values and the precision did not exceed $15\%$ of relative standard diviation. The lower limits of quantitation were 50 ng/ml for both TRF and PRF. The distribution of TRF or PRF was determined by 48 h after i.m. administration of the combination mixture at a dose of 30 mg/kg ACF. TRF and PRF were distributed as the following order; kidney>lung>liver>small intestine>muscle. Of the various tissues, TRF and PRF were mainly distributed to the kidney and lung. The concentrations of TRF or PRF in the tissues 24 h after i.m. administration decreased to undetectable levels. The concentrations of TRF or PRF in the blood cells were comparable to those for the plasma. However, the concentrations of TRF or PRF in the both plasma and blood cells 12 h after i.m. administration were not detected. The number of the platelets in the 1 ml of the blood was calculated to be $0.183{\times}10^8/ml$ of blood. The PRF concentration in platelets was higher than that of TRF at initial times after i.m. administration of the combination mixture. However, both the TRF and PRF concentrations in the plateles 24 h after i.m. administration of the combination mixture were below the quantifiable limit. In conclusion, the concentrations of TRF or PRF in the various tissues, plasma, blood cells, and plateles decreased to undetectable levels 24 h after i.m. administration of the combination mixture at a dose of 30 mg/kg ACF.
The cactus family Cactaceae, numbering about 1,500 species, is a fleshy-stemmed perennial plant which is principally distributed in the south and north America. On the other hand, the cactus plant is presumed to be introduced into Korea in 1912-1945, thereafter it has been cultivated merely in favor of ornamentation with the exception of being occasionally used as medication among laymen. Opuntia elata which belongs to Opuntia genus, the Cactaceae family is one of the cacti being cultivated a great deal in Korea. Cho et. al. reported in 1974 that Opuntia dilenii manifested the cardiac inhibitory effect and oxytocic effect, and its mechanism might be partially due to the direct action. Besides this, there are few reports on the pharmacological research concerning Opuntia genus to be demonstrated in Korea. However, some other cacti have the remarkable pharmacological effects; the active ingredients, mescaline, anhalamine, anhalanine, etc. from Peyote cactus (Lophophora williamsii) belonging to Lophophora genus have the psychotomimetic and sympathomimetic effects, and the cardioactive glycosides from Cactus Grandifolius (Selenicereus grandiflorus) belonging to Cereus genus have the cardioactive and diuretic effects. The authors hereby inquired into this study to find out the propriety of the pharmacological properties of the ethanol extract of Opuntia elata (EX) on the heart, blood pressure, respiration, intestine and uterus in the experimental animals. The results of the experiment were as follows: 1. Administration of EX manifested the cardiac inhibitory effect caused by the negative inotropic action in the isolated heart of frog, and the pretreatment of atropine did not affect the inhibitory effect produced by EX. 2. Administration of EX manifested the transient hypotensive effect in the intact rabbit, and the pretreatment of atropine did not affect the hypotensive effect produced by EX. 3. Administration of the small dose of EX manifested no significant effect, but moderate dose or more the stimulating effect, and the large dose the asphyxia on the respiratory motility in the intact rabbit. 4. Administration of EX manifested the sustained augmentation of contractility in the excised duodenum of rabbit, and the pretreatment of atropine did not affect the stimulating effect produced by EX. 5. Administration of EX manifested the sustained augmentation of contractility in the excised pregnant uterus of rabbit, and the pretreatment of atropine and oxytocin did not affect the oxytocic effect produced by EX, but that of barium chloride more or less stimulated the oxytocic effect produced by EX.
Objectives : Korean traditional acupuncture Theory, Sa-am's 5 phases acupuncture method was originated in 1644-1742, in the middle of the Cho Sun dynasty. This study was to verify the effect of Sa-am Acupuncture Treatment on dysmenorrhea of Women. Methods : The subjects were 49 volunteers who were suffering for dysmenorrhea, employed using Measure of Menstrual Pain (MMP) questionnaire. Subjects were divided into two groups including Sa-am acupuncture treatment group(n=23) and minimal acupuncture treatment group(n=26). They had agreed to take part in tIris experiment, with didn't take any anodyne drugs. In the acupuncture group, subjects were stimulated at $GB_{41}$, $SI_3$, $GL_{66}$, $SI_2$(Small intestine jung-guk) and $SP_6$. In the control group, subjects were needled at $L_{10}$, $S_{40}$, $P_5$, $G_{40}$ points have any effect on dysmenorrhea. A total of 5 acupuncture sessions were performed for each patient depending on the individual menstruation cycle. The MMP score by using 7 questions and the Menstrual Symptom Severity List(MSSL-D) were measured before and after menstruation cycle. Collected data were analyzed as frequency, percentage, paired t-test, independent t-test using SPSS 10.0 WIN Program. Results : Acupuncture treatment produced a significant improvement on dysmenorrhea in two groups, but a statistically significant difference was not shown in the acupuncture group compare to control group. Conclusions : Based on the above results, it was verified that Acupuncture Treatment was effective in decreasing the symptom of Dysmenorrhea.

Although the sesame lignans, sesamol, have been shown to possess antioxidative activity, less is known about the metabolism and antioxidative properties of sesamol, a major constituent of sesame oil. To determine the ability of sesamol to act as an antioxidant in vivo, we fed rats a diet containing 0.5% sesamol for 3 wk and studied its metabolism and its effects on oxidative stress. Body weight gain and weight of liver, kidneys were significantly higher in the rats fed sesamol than in rats fed the control diets. GST and GST-Px activities in rat liver microsomes were higher in rats fed sesamol and CAT activities were found to be significantly increased in rats fed sesamol. The formation of TBARS was decreased in the liver of rat fed the 0.5% sesamol diet than in controls. We detected sesamol metabolites in liver and kidneys of rats fed sesamol and its metabolites were present as conjugated glucuronides and sulfates. In contrast, not detected sesamol peak in other organs such as colon, small intestine and pancreas.
The present study was conducted to evaluate the effect of the dietary supplementation of Bacillus amyloliquefaciens-based direct-fed microbial (DFM) on growth performance, nutrient utilization, intestinal morphology and cecal microflora in broiler chickens. A total of two hundred and eighty eight 1-d-old Arbor Acres male broilers were randomly allocated to one of four experimental treatments in a completely randomized design. Each treatment was fed to eight replicate cages, with nine birds per cage. Dietary treatments were composed of an antibiotic-free basal diet (control), and the basal diet supplemented with either 15 mg/kg of virginiamycin as antibiotic growth promoter (AGP), 30 mg/kg of Bacillus amyloliquefaciens-based DFM (DFM 30) or 60 mg/kg of Bacillus amyloliquefaciens-based DFM (DFM 60). Experimental diets were fed in two phases: starter (d 1 to 21) and finisher (d 22 to 42). Growth performance, nutrient utilization, morphological parameters of the small intestine and cecal microbial populations were measured at the end of the starter (d 21) and finisher (d 42) phases. During the starter phase, DFM and virginiamycin supplementation improved the feed conversion ratio (FCR; p<0.01) compared with the control group. For the finisher phase and the overall experiment (d 1 to 42) broilers fed diets with the DFM had better body weight gain (BWG) and FCR than that of control (p<0.05). Supplementation of virginiamycin and DFM significantly increased the total tract apparent digestibility of crude protein (CP), dry matter (DM) and gross energy during both starter and finisher phases (p<0.05) compared with the control group. On d 21, villus height, crypt depth and villus height to crypt depth ratio of duodenum, jejunum, and ileum were significantly increased for the birds fed with the DFM diets as compared with the control group (p<0.05). The DFM 30, DFM 60, and AGP groups decreased the Escherichia coli population in cecum at d 21 and d 42 compared with control group (p<0.01). In addition, the population of Lactobacillus was increased in DFM 30 and DFM 60 groups as compared with control and AGP groups (p<0.01). It can be concluded that Bacillus amyloliquefaciens-based DFM could be an alternative to the use of AGPs in broilers diets based on plant protein.

The method of intestinal Ca absorption in rats was studied by injecting the test solution of $^{45}Ca$ into ligated ileal loops (an in situ closed gut sement technique). The amount of Ca absorbed was measured in regard to the amount of soluble $^{40}Ca$ and $^{45}Ca$ which disappeared from the ligated ileal loops for 30min, and appeared portal blood for 15 min after the injection. The 15~20cm ligated segment of mid ileum and the test solution containing $0.2{\sim}0.5{\mu}Ci$$5{\mu}g$ Ca/0.5ml, pH 7.0, $37^{\circ}C$ are appropriate for this in situ closed gut segment technique which turn out to be highly available for study of Ca absorption. The rats fed casein diet absorbed more Ca by 2~5 times than the rats fed egg albumin diet.

Purpose: The incidence of nosocomial infection caused by Gram-negative bacilli (GNB) has increased in neonatal intensive care units (NICU). This study identified the progression of sepsis caused by GNB colonization and analyzed the risk factors associated with using periodic stool culture surveillance. Methods: We included 86 newborns admitted to the NICU, Kosin University Gospel Hospital from October 2007 to May 2008. Three stool specimens were collected right after birth and two more were collected at 2 week intervals. The risk factors related to GNB colonization were established from each medical record and related references. Results: The incidence of colonization by GNB was 22 (25.6%) per 86 neonates but none had culture-proven sepsis. The three most commonly isolated GNB were Pseudomonas aeruginosa, Enterobacter cloacae, and Citrobacter freundii. Approximately 89% (32/36) of isolated GNB were susceptible to amikacin. The probability of GNB colonization increased in infants who were fed a small volume during enteral feeding. In contrast, delayed enteral feeding resulted in a decreased probability for GNB colonization. Conclusion: Colonized GNB in the intestine was confirmed by enteric surveillance culture of newborns admitted to the NICU. However, we found no evidence of culture-proven GNB sepsis. As lower feeding volume on the colonization day is a risk factor for GNB colonization, the chance for GNB colonization should be considered when feeding intolerance is present.

Extracts and fractions of Inonotus obliquus (Chaga in Russia) have been known to have various biological activities, including antimutagenic, anticancer, antioxidative, and immunostimulating effects. This study was performed to confirm anticancer effect of 10% superfine Chaga mushroom processed by nano-mill technology on C57BL/6 mice. Chaga particles belonged in the size of 1 ${\mu}m$ was about 40% after nanomill processing according to the volume distribution. As the result of subcutaneous injection of B16BL6 melanoma cells to the mice, the tumor volume (p<0.001) and tumor weight (p<0.01) was significantly decreased in the experimental (NCh) group as compared with control (C) group and the tumor growth inhibitory rate was 29.2%. On examination of survival rate after intraperitoneal injection of B16BL6 melanoma cells, the mean survival time per a mouse was 17.7 and 26.0 days in C and NCh group respectively. The survival rate of NCh group was 40% when that of C group was 0% at the 35th day. On the result of examination to confirm histological toxicity by Chaga superfine particles, both groups did not show any morphological and pathological changes in the small and large intestine under the light microscope. These results suggest that feeding of superfine Chaga produced by nanomill technique has a tumor growth inhibitory effect in vivo.

Cyanidin-3-O-glucoside (C3G) shows anti-inflammatory and antioxidant effects; however, its effect on postprandial blood glucose levels remains unknown. Alpha-glucosidase inhibitors regulate post-prandial hyperglycemia by impeding carbohydrate digestion in the small intestine. Here, the effect of C3G on ${\alpha}-glucosidase$ and ${\alpha}-amylase$ inhibition and its ability to ameliorate postprandial hyperglycemia in streptozotocin (STZ)-induced diabetic mice were evaluated. ICR normal and STZ-induced diabetic mice were orally administered soluble starch alone or with C3G or acarbose. The half-maximal inhibitory concentrations of C3G for ${\alpha}-glucosidase$ and ${\alpha}-amylase$ were 13.72 and $7.5{\mu}M$, respectively, suggesting that C3G was more effective than acarbose. The increase in postprandial blood glucose levels was more significantly reduced in the C3G groups than in the control group for both diabetic and normal mice. The area under the curve for the diabetic mice was significantly reduced following C3G administration. C3G may be a potent ${\alpha}-glucosidase$ inhibitor and may delay dietary carbohydrate absorption.
