  • Background : Since up to 90% of a theophylline dose is biotransformed, probably by interaction with one or more the variants of the cytochrome P-450 drug metabolism system, anti-tuberculosis agents including drugs influencing microsomal enzyme systems, such as isoniazid and rifampicin. may be affect the elimination of theophylline. Method : The effect of combination therapy with isoniazid(INH), rifampicin(RFP), ethambutol(EMB) and pyrazinamide(PZA) on the pharmacokinetics of theophylline was evaluated by a computer program using Bayesian method. Three group were divided as follows. Group I is control, Group II is treated with INH. RFP, EMB and PZA and Group III is treated with INH, RFP and EMB. All of them were ilon-smoker who were normal in liver and renal functions, and not administered drugs affecting on the clearance of theophylline with exception of anti-tuberculous agents. Results : When it compared control with test groups, the clearance of theophylline in Group II and Group III was significantly decreased(p<0.001), and half life in Group II and Group III showed significant elevation(p<0.001). However there were no significant differences in clearance and half life between the Group II and Group III. Conclusion : These results suggest that theophylline dose may be need of readjustment in concurrent medication of anti-tuberculous agents including INH, RFP, and EMB.

  • The aim of this study was to investigate the effects of dry-aging (DA) and the cooking process on the myofibril protein functionalities and in vitro digestibility of proteins in beef loin. Six sirloins from beef were dry-aged for 28 d, and the control group (n=6) was analyzed 2 d postmortem for this study. Dimensional changes (reduction of thickness and surface shrinkage) after cooking were significantly greater in the control group than the DA group, whereas the shear force of the DA group was significantly lower than that of the control. Effect of cooking on aggregation, hydrophobicity, and in vitro digestibility were significantly higher in the DA group than in the control. After cooking, the protein in DA sirloins was more oxidized than in the control samples. According to the sodium dodecyl sulfate-polyacrylamide gel electrophoresis result, the low molecular weight bands (below 17 kDa) increased in the DA group, finding that the protein characteristics of dry-aged beef was affected by cooking.

  • In this study we investigated the neuroprotective, antioxidative, and hypocholestrolemic effects of dietary soy protein and soy isoflavone in a rat focal brain ischemia model. Weaning Sprague-Dawley rats were fed a 20% casein-based diet (CA), 20% soy protein-based diet (SP), or 0.2% soy isoflavones-supplemented diet (ISO) for 6 weeks. The cortical infarction volume of the ISO group was significantly lower than that of the SP group. The thiobarbituric acid reactive substances (TBARS) were considerably lower in the ISO group than the CA group. Glutatbione peroxidase activities of the SP group were notably higher than those of the CA group. Acetylcholinesterase (AchE) activities of the SP group were significantly decreased compared to the CA group. LDL cholesterol levels and LDL/HDL ratios of the ISO group were lower than those of the CA and SP groups. Our results collectively suggest that soy isoflavones may contribute to neuroprotection by reducing the TBARS and serum LDL/HDL ratio, whereas soy protein may be associated with the regulation of cognitive functions by modulating AchE activity.

  • Background: The aim of this study was to compare the efficacy of ketorolac, paracetamol, and paracetamol plus morphine on pain relief after thyroidectomy. Methods: Eighty patients were randomly allocated to one of the 4 groups: normal saline (group C), ketorolac 30 mg (group K), paracetamol 1 g (group P), and paracetamol 700 mg plus morphine 3 mg (group PM). Each regimen was administered intravenously (IV) 30 min. before the end of surgery. If pain was not relieved, patients received an IV bolus of pethidine hydrochloride 25 mg. Pain intensity using a visual analogue scale (VAS) was recorded at 0.5, 1, 2, 4, and 6 hr after the end of surgery. Results: VAS at 0.5 and 1 hr after the end of surgery were significantly lower in group K, group P, and group PM than in group C (P < 0.05). The number of patients receiving pethidine hydrochloride at 0.5 and 1 hr after the end of surgery was significantly lower in group K, group P, and group PM than in group C (P < 0.05). There was no significant difference among the groups in the incidences of adverse events associated with study medications and patient satisfaction (P > 0.05). Conclusions: Paracetamol 1 g IV possesses a similar analgesic efficacy to ketorolac 30 mg IV after thyroidectomy. Paracetamol may represent an alternative to ketorolac for pain prevention after mildly to moderately painful surgery in situations where the use of NSAIDs is unsuitable.

  • Objectives : The purpose of this study is to evaluate the feasibility of massive clinical research and to make a basic analysis on the effectiveness and safety of moxibustion treatment on knee osteoarthritis compared to usual care. Methods and Results : This study is a protocol for a pilot randomized controlled trial. Forty participants are assigned to the moxibustion group (n=20) and usual care group (n=20). Participants assigned to the moxibustion group receive moxibustion treatment on the affected knee(s) at six standard acupuncture points (ST36, ST35, ST34, SP9, Ex-LE04 and SP10) three times per week for four weeks (total of 12 sessions). Participants in the usual care group don't receive moxibustion treatment during the study period and follow-up are made on the 5th, 9th and 13th weeks after random allocation. Both groups are allowed to use any kind of treatment, including surgery, conventional medication, physical treatment, acupuncture, herbal medicine, over-the-counter drugs and other active treatments. Education material that explains knee osteoarthritis and current management options and self-exercise is provided for each group. The pain scale of the Korean Western Ontario and McMaster Universities Questionnaire (K-WOMAC) is the primary outcome measurement used in this study. Other subscales of the K-WOMAC, the Short-Form 36 Health Survey (SF-36), Beck Depression Inventory (BDI), Physical Function test, Patient Global Assessment, and Pain Numeric Rating Scale (NRS) are used as outcome variables to evaluate the effectiveness of acupuncture. Safety is assessed at every visit. Conclusions : The result of this trial will provide a basis for the effectiveness and safety of acupuncture treatment for knee osteoarthritis.

  • Let G be a finite group and N be a normal subgroup of G. We denote by ncc(N) the number of conjugacy classes of N in G and N is called n-decomposable, if ncc(N) = n. Set $K_{G}\;=\;\{ncc(N)$\mid$N{\lhd}G\}$. Let X be a non-empty subset of positive integers. A group G is called X-decomposable, if KG = X. In this paper we characterise the {1, 3, 4}-decomposable finite non-perfect groups. We prove that such a group is isomorphic to Small Group (36, 9), the $9^{th}$ group of order 36 in the small group library of GAP, a metabelian group of order $2^n{2{\frac{n-1}{2}}\;-\;1)$, in which n is odd positive integer and $2{\frac{n-1}{2}}\;-\;1$ is a Mersenne prime or a metabelian group of order $2^n(2{\frac{n}{3}}\;-\;1)$, where 3$\mid$n and $2\frac{n}{3}\;-\;1$ is a Mersenne prime. Moreover, we calculate the set $K_{G}$, for some finite group G.

  • Let R be a commutative ring, G be an Abelian group, and let RG be the group ring. We say that RG is a U-group ring if a is a unit in RG if and only if ${\epsilon}(a)$ is a unit in R. We show that RG is a U-group ring if and only if G is a p-group and $p{\in}J(R)$. We give some properties of U-group rings and investigate some properties of well known rings, such as Hermite rings and rings with stable range, in the presence of U-group rings.

  • We conducted this study to examine the effects of safflower seed granular tea containing physiologically active polyphenols on antioxidative activities and bone metabolism. Forty postmenopausal women ages 49 to 64-years were recruited from Daegu and Gyeongbuk and were randomly assigned to either a safflower tea supplement (Saf-tea) group (n=27) or a placebo group (n=13). The Saf-tea group received 20 g of safflower seed granule tea per day containing a 13% ethanol extract of defatted safflower seeds, whereas the placebo group received a similar type of tea that lacked the ethanol extract. No significant changes in nutrient intake for either the placebo or Saf-tea groups were observed before or after the study period, except vitamin A intake increased after 6 months in the Saf-tea group. Dietary phytoestrogen intakes were similar in the Saf-tea group (60.3 mg) and placebo group (52.5 mg). Significant increases in plasma genistein and enterolactone were observed in the Saf-tea group. After 6 months of supplementation, serum levels of antioxidant vitamins such as a-tocopherol and ascorbic acid increased significantly, and TBARS levels decreased in the Saf-tea group compared to the placebo group. Serum osteocalcin levels were reduced (P<0.05) in the Saf-tea group after 6 months, whereas serum osteocalcin did not change in the placebo group. Urinary deoxypyridinoline/creatinine excretion was not different between the two groups at baseline, and did not change in either group after 6 months. Bone mineral density decreased significantly in the placebo group (P<0.01) but not in the supplemented group. It was concluded that polyphenols (72 mg/day), including serotonin derivatives, in the Saf-tea had both antioxidant and potential bone protecting effects in postmenopausal women without liver toxicity.

  • This experiment was carried out to investigate effects of honeybee venom treatment on the body weight gain, feed conversion and growth rate' in pigs. One hundred twenty nine piglets(LY) from 12 sows were allocated into two groups; honeybee venom-treated group (66 piglets from 6 sows) and non-treated control group (63 piglets from 6 sows). Natural honeybee venom was administrated at 0, 3, 14, 30, and 74 days after birth. The acupoints were Hai-men(ST-25), Du-kou(CV-8) and liao-chao(GV-I) points at 0 day, the regions of castration and tail ampution at 3 days, liao-chao(GV-1) and Bai-hui(GV-20) points at 14(weaning), 30(move into piglet stall) and 74(move into grower stall) days after birth. Control group was injected 1 ml of saline to the same site. Average body weight at 150 days after birth was 98.44 kg in bee venom treated group and 86.24 kg in control group, respectively. Average body weight of treated group was significantly increased by 14.15%(P < 0.0001). Average daily gain of bee venom treated group and control group were 649 g and 569 g, respectively, increased by 14.06%(P< 0.0001). Feed conversion of the treated group was 2.21 and control group was 2.49, increased by 11.25% in control group(P < 0.001). Survival rate at weaning was 95.5 % in treated group and 92.0% in control group, at growing(74 days after birth) was 92.4% in treated group and 85.7% in control group and survival rate at finishing(l50 days after birth) was 89.5 % and 79.4 %, respectively. Collecting together, the results in this study showed that growth performance and feed conversion were increased by treatment of natural honeybee venom to pigs. These results suggested that the treatment of bee venom could be used effectively for the increase productivity of livestock industry.
