  • In order to investigate the possibility of lwo fat meat products, beef patties were prepared with gums such as carrageenan, methyl cellulose, and xanthangum. The quality characteristics of beef patties were examined. Moisture contents of raw and cooked patties of control were lower than those of patties containing gums, and fat content was higher than those of containing gums. There was no significant difference in the protein contents of patties. In case of L-value(lightness) of raw patty, the control was higher than those patties containing gums. a-(redness) and b-value(yellowness) among patties were not significantly different. Cooking yield, fat retention, and water holding capacity of beef patties containing gums were higher than control beef patty, but salt soluble protein and gel strength were not significantly different. Significant difference did not exist among beef patties in hardness, but the chewiness and gumminess of patties containing gums were higher than control. In case of sensory evaluation, there was no significant difference among patties in aroma and palatability. Texture of control was higher than patties containing gums, and juiciness of control was higher than patties containing carrageenan.

  • 겔화제의 종류에 따른 겔상식품의 특성을 알아보고자 대조군인 한천첨가 양갱과 다양한 겔화제를 혼합 사용한 양갱을 제조하고 그 특성을 비교하였다. 첨가되는 겔화제의 특성은 최종 제품의 수분손실량, 색, 조직감 등의 물리적 특성에 크게 영향을 미치는 것으로 나타났다. 덜 조밀하고 가장 불규칙적인 단면특성을 보이는 gellan 첨가 양갱은 수분 손실이 가장 크고, 가장 부드러우면서도 입에 들러붙는 부착성이 큰 특성을 보였다. 반면, LBG+carrageenan 겔의 혼합은 두 겔의 상호작용으로 단단한 겔을 만들기 때문에 이를 첨가한 양갱 역시 가장 단단한 경도를 보였다. 본 연구결과 고령자들은 너무 단단하지 않으면서도 응집성이 높고 탄력성이 있어 씹을 수 있는, 그러나 입에 들러붙는 부착성이 낮은 겔상 식품을 선호하는 것으로 나타났다. 두 종류의 겔을 혼합하여 적절한 농도로 겔을 제조하면 경도, 부착성, 및 응집성 등의 조직감 특성을 다양화 할 수 있으므로 적절한 겔화제의 선택, 농도조절 등으로 고령자의 저작능력에 맞는 다양한 물성을 갖는 식품제조가 가능할 것으로 생각된다.

  • Gel and cream containing 5% and 10% ketonic fraction (KF) of Leptospermum scoparium, respectively were formulated. Antimicrobial activity, stability, anti-inflammatory effect, rheological properties, drug release and acute toxicity for these topical efficacy were evaluated. Gel and cream containing neomycin or gentamycin in combination with KF has potent antimicrobial activity. Gel and cream were physically stable and did not show any creaming for 6 months storage. Gel showed plastic flow with yield value and cream showed pseudoplastic flow with hysteresis loop. The gel and cream containing KF showed higher viscosity than control or commercial one. The viscosity increased as the concentration of KF increased. Both 10% gel and cream showed a significant decrease in swelling when applied to the carrageenan- injected paw, suggesting local antiinflammatory activity. Particularly, 10% gel preparation showed similar antiinflammatory activity when compared with commercially available drugs. Percent of drug released and diffusion coefficient were in the order of 5% gel, 10% gel, 5% cream, and 10% cream, respectively. There were no significant changes of body weight in rats percutaneously administered with 10% cream and gel when compared with control. There were no induced acute toxicity when 10% cream or gel was applied to rats. Leptospermum scoparium could be practicaly used in topical preparations.

  • The aerial part of Siegesbeckia pubescens (Compositae) has been used to treat rheumatoid arthritis and hypertension in the Oriental medicine. This crude drug has been used without process (SP-0) or with three times-process of steaming and drying (SP-3) or the nine times of that process (SP-9). To search for the antinociceptive anti-inflammatory components from this crude drug, activity-directed fractionation was performed on this crude drug. Since the $CHCl_3$ extract was shown to have a more potent effect than other extracts, it was subjected to silica gel & ODS column chromatography to yield two diterpene compounds (1). Compound 1 was structurally identified as ent-16 (H, 17-hydroxykauran-19-oic acid, which were tentatively named siegeskaurolic acid A. A main diterpene, siegeskaurolic acid A was tested for the antiiflammatory antinociceptive effects using both hot plate- and writhing anti-nociceptive assays and carrageenan-induced anti-inflammatory assays in mice and rats. Pretreatment with siegeskaurolic acid A (20 and 30mg/kg) significantly reduced the stretching episodes, action time of mice and carrageenan-induced edema. These results support that siegeskaurolic acid is a main diterpene responsible for antinociceptive and antiiflammatory action of S. pubescens. In addition, the assays on SP-0, SP-3 and SP-9 produced the experimental results that SP-9 had more significant effects than other two crude drugs. These results suggest that the processing on the original plant may lead to the higher pharmacological effect.

  • This study was performed to investigate the effects of treatment for dermatitis using the herbal gel preparations. Scutellariae Radix(SR) and Zingiberis Rhizoma(ZR) were used for the purpose of herbal preparations. Baicalin, baicalein are the ingredients of SR, having biological effects like anti-inflammatory, anti-oxidative, anti-bacterial and antiallergic action. 6-Gingerol is one of the ingredients of ZR having biologicai effects like anti-inflammatory and analgesic action. The three types of hydrogels(SRE, SRH, SZH) were formulated with Carbopol 940, Labrasol, Triethanolamine etc. Baicalin was hydrolysed to baicalein by $\beta$-glucuronidase for the purpose to increase rate of skin permeation. Content of ingredients by HPLC determination, rate of skin permeation using Franz type diffusion cell, anti-oxidative activity for the free radical, hydroxyl radical, superoxide, anti-inflammatory by using carrageenan injection, efficacy on the dermatitis induced by 2,4-dinitro-chlorobenzene(DNCB) were experimented. Baicalein showed higher permeability than baicalin, so it is considered that baicalein was more suitable form than baicalin for transdermal absorption by its lipophilic property. In the anti-oxidative experiments, SZH gel was the most effective scavenging activity than the other gels in all experiments. In anti-inflammatory test, SRM and SZH gel more decreased edma rapidly than SRE gel. In case of using SZH gel, treatment period for the dermatitis was more declined than that of other gel groups. These results suggests that the SZH hydrogel could be suitable preparations for the treatment of dermatitis.

  • This study was carried out to determine the effects of various contents of kiwifruit contents on the quality characteristics of mixed polysaccharide gels made from $\kappa$-carrageenan and locust bean gum. The color value, gelling temperature, melting temperature, break down rate, syneresis, rupture properties, TPA properties and sensory properties of mixed polysaccharide gels with various contents of kiwifruit contents were measured. As the kiwifruit contents was increased, the lightness (L), yellowness (b) and greenness (-a) of the mixed polysaccharide gels increased. There were no differences in the color values of gels during storage. As the kiwifruit content was increased, the gelling and melting temperatures of the mixed polysaccharide gels also increased. The mixed polysaccharide gels with high kiwifruit contents were difficult to melt, and it seemed that the addition of kiwifruit to the mixed polysaccharide gels could improve the thennal stability of the gels. The syneresis of the gel increased with increasing storage time, whereas the addition of kiwifruit to the gel resulted in suppression of syneresis. With regard to the rupture properties, stress, energy and strain, they were all decreased with increasing kiwifruit contents. The TPA properties, adhesiveness, hardness and chewiness increased and cohesiveness decreased with increasing kiwifruit contents. The results showed that the gel became tough and adhesive, and could be easily broken under small deformation, with increasing kiwifruit contents. The sensory evaluation showed that the green color, aroma, sweetness and sourness increased with increasing kiwifruit contents. The texture, adhesiveness, springiness and cohesiveness decreased, and brittleness and hardness increased, with increasing kiwifruit contents. The overall acceptability of the gel with 30% kiwifruit content was the highest. Thus, mixed polysaccharide gels made from kiwifruits could be useful, as the addition of kiwifruit to a mixed polysaccharide gel results in a good aroma, taste and stability, despite a lowering of the textural properties.

  • This study aims to examine the effects on nociceptive neuron excitability by application of electroacupuncture and Meloxicam gel in rat with inflammation. It used 24 rats for experiment, divided them into control group, electroacupuncture group(EA group), Meloxicam group(ME group), combination of electroacupuncture with Meloxicam group(EA+ME group), caused hyperalgesia by injecting ${\lambda}$-carrageenan into hindpaw and conducted treatment three times for experimental period. Noxious flexion withdrawal reflex(NFR) and somatosensory evoked potential(SEP) were measured immediately after induction, at 24 hours, 48 hours and 72 hours after induction. Change of NFR(reaction time, RMS) showed no significant differences among EA group, Meloxicam group, and EA+Meloxicam group, but all treatment groups showed significant differences compared to control group from 48 hours. In NFR threshold, there were significant differences between EA+Meloxicam and other groups. In SEP amplitude, there were significant differences between EA+Meloxicam and control group from 48 hours. This study showed that EA+Meloxicam gel had an effect on nociceptive neurone excitability. Therefore, it is considered that appropriate combination of anti-inflammatory drug with electroacupuncture for pain control will be very desirable.

  • Transdermal permeation enhancer has been used to increased skin absorption. External control of drug release and skin absorption can also be achieved by iontophoresis or phonophoresis. However, because several problems with iontophoresis are that it has a risk to skin damage because of the change of pH and the increase of current density in applying it and that it can be applied only in the form of water solution, This study is to enhance drug permeation via skin following application of ultrasound. For this goal, in gel containing piroxicam, the degree of skin permeation in vitro and anti-inflammatory effect in in vivo were investigated. Permeation study using hairless mouse skin was performed at 37 $^{\circ}C$ using buffer saline as the receptor solution. The amount of piroxicam were quantified using a HPLC system consisting of solvent delivery system. Following adoption of ultrasound 1 MHZ, it showed relatively high permeation rate where it was compared with non treated by ultrasound. The influence of duty cycle having an effect on skin permeation rate was slight higher in the case of using pulsed mode. Skin permeation increase attended by intensity of ultrasound, the permeation of trice was accelerated at 2.0 W/$cm^{2}$ than 1.0 W/$cm^{2}$. The skin permeation of piroxicam was substantially influenced by ultrasound. Anti-inflammatory effects were determined using carrageenan-induced paw swelling method in SD rat. Paw swelling tests showed that pulsed phonophoresis group was more effective than control group and only gel application group. The conclusion of phonophoresis was found to improve significantly the skin permeation in vitro and the anti-inflammatory effect in vivo.
