  • UI14SDF100CW is a chewable tablet of sildenafil citrate, which was developed to improve compliance through convenience of administration. The purpose of this study was to compare the pharmacokinetic (PK) properties of sildenafil citrate chewable tablets (UI14SDF100CW) and conventional sildenafil citrate film-coated tablets ($Viagra^{(R)}$, Pfizer). A randomized, open-label, single dose, two-treatment, two-period, two-way crossover study was conducted in 60 healthy male volunteers. In each period, the subjects received a single oral dose of UI14SDF100CW or $Viagra^{(R)}$ (both tablets contain 140.45 mg of sildenafil citrate, which is equivalent to 100 mg of sildenafil). Serial blood samples were collected up to 24 h post-dose for PK analysis. The plasma concentration of sildenafil was determined using a validated HPLC-MS/MS assay. PK parameters of sildenafil were calculated using non-compartmental methods. The plasma concentration-time profiles of sildenafil in both formulations were similar. For UI14SDF100CW, the $C_{max}$ and $AUC_{last}$ of sildenafil were $1068.69{\pm}458.25$ (mean${\pm}$standard deviation) mg/L and $3580.59{\pm}1680.29h{\cdot}mg/L$, and the corresponding values for $Viagra^{(R)}$ were $1146.84{\pm}501.70mg/L$ and $3406.35{\pm}1452.31h{\cdot}mg/L$, respectively. The geometric mean ratios (90% confidence intervals) of UI14SDF100CW to $Viagra^{(R)}$ for $C_{max}$ and $AUC_{last}$ were 0.933 (0.853-1.021) and 1.034 (0.969-1.108), respectively, which met the bioequivalence criteria of Korean regulatory agency. In conclusion, UI14SDF100CW and $Viagra^{(R)}$ showed similar PK properties. Therefore, UI14SDF100CW can be an alternative to sildenafil for the treatment of erectile dysfunction, providing better compliance.

  • Focusing on head temples in 25 parishes of Jogye Order, this study compared and analyzed the ancient literatures involved in the writing source of pillar tablets and the space layout drawings in order to examine awareness patterns of space in terms of contents of pillar tablets and Buddha and Bodhisattva enshrined in major temple sanctums in Korea. The research findings are briefed as follow: First, the different Buddhas enshrined in sanctums can be categorized and explained in accordance with their body(體), form(相) and use(用) based on Awakening of Mahayana Faith. In particular, Sakyamuni Buddha is for form(相), Amitabha Buddha and Avalokiteśvara for use(用), and Vairocana Buddha for body(體). Second, the pillar tablets of main sanctums signify oath and thoughts of the enshrined Buddhas and Bodhisattvas focusing on main Buddhas and serving Buddhas. Third, the content of pillar tablets is to symbolize and signify Buddha land where main Buddhas are always existing as they are focusing on the enshrined main Buddhas. That is, such content is to praise for Buddha. Fourth, every sanctum pillar tablets of temples express the content of attaining spiritual enlightenment for the self-cultivating truth seekers and saving all sentient beings for main Buddhas who are saving human. That is, every space of temples are perceived as "escaping torment and achieving pleasure(避苦得樂)".

  • Biological activities of wax gourd (Benincase hispida) extract and lactic acid bacteria (Lactobacillus casei and Bifidobacterium bifidum) were investigated in this study. Wax gourd extract reduced the activity of angiotensin-converting enzyme (ACE) by 47.9%, of tyrosinase by 13.2%, and had an anti-oxidant activity of 23.4%. Oral administration of wax gourd extract for 72 hours improved the symptom of loose bowels for 120 patients with its highest improvement rates within 6 to 12 hours. The improvement rates were standardized by the curative state by 80%. Lactic acid bacteria preparations reduced the activity of ACE by 21.49%. Oral administration of lactic acid bacteria preparations for 72 hours improved the symptom of loose bowels for 108 patients with its highest improvement rates after 24 hours. On the basis of these results, the tablets containing both wax gourd extract and lactic acid bacteria preparations for the improvement of irritable bowel syndromes were developed. The tablets reduced the activity of ACE by 27.1% and exhibited an anti-oxidant activity of 20.3%. Treatment of the tablets at 100 ${\mu}g/m{\ell}$ and 250 ${\mu}g/m{\ell}$ for 24 hours inhibited the growth of A549 human lung cancer cells by 67%, which was much higher than that of each wax gourd extract or lactic acid bacteria. In addition, treatment of the tablets at 100 ${\mu}g/m{\ell}$ for 24 hours reduced the growth of HCT-116 human colon cancer cells by 70%. Oral administration of the tablets to the patients with loose bowels led to higher improvement rates and speed than each wax gourd extract or lactic acid bacteria. Oral administration of the tablets to the patients with irritable bowel syndromes of loose bowels, constipation, or general type for 72 hours improved their symptoms by 100% with the highest improvement rates within 3 to 6 hours. Furthermore, the improvement rates and speed by the tablets was much higher than each wax gourd extract or lactic acid bacteria.

  • A Gamsil is an ritual instrument which enshrine the ancestral tablets of four lines from late great-great-grandfather and grandmother to late father and mother. This has their soul. Juja's "Garye" informs its structure pattern. It is placed in Sadang and takes the form of a perfectly square box. It partitions four rooms and enshrine an ancestral tablet room by room. They get the ancestral tablets line up from west to east. And they also enshrine the ancestral tablets without his descendant together in Gamsil. A Gamsil is a space to enshrine the ancestral tablets and to place an order within a family. A social status and A family economic power become a standard in making and managing Sadang. Kingdom in Joseon period limited the ancestral tablets considering of his degree of official rank which descendant enshrined. A official servant can be stable economically in getting a stipend and build sadang in the house. While household a little in economic enshrine the ancestral tablets at a Gamsil placed at the a space of private home. His personal circumstances make size and pattern, place change in relation to Gamsil. A Gamsil looks like house in structure and pattern. It has the immortality of the soul. And it changed from a table size to a ancestral tablet size. This Gamsil is comfortable to move and is made considering of the width and height of household. The transition of Gamsil means institutions is in close to a family economic power in social change. Kingdom in Joseon early period makes a policy of a Gamyo's build and an ancestral enshrine in basement of Juja's "Garye". The transition of Gamsil gave a common people limitted socially and institutionally the service of late four lines. Most of people enshrine the ancestral tablets of their four lines in approaching of in the late of Joseon Dinasty. They compromise on their reality and cause. The transition of Gamsil implied many different things in social ; the authenticity search and a dignity expression of his family, the foundation for the diffusion of an ancestral service, a space sharing with ancestor and descendent, the increment of a family economic power etc.

  • Caffeine is widely consumed ingredient and it belongs to alkaloids. Many foods that we intake contain caffeine ; coffee, tea cocoa, chocolate, and coke. And it is also added to many commercial remedies ; cold tablets, headache tablets, etc. Effect of caffeine that is known to us so far is as follows; 1. Remaining awake for long hours 2. Increasing concentration and decreasing fatigue 3. Increasing basal metabolic rate 4. decomposing glycogen and body fat and providing energy 5. Stimulating gastric acid 6. Increasing urinary excretion. Caffeine containing beverages(especially, coffee)are also favorite food in adult. In case of children and youth, chocolate and coke are favorite food. So, to intake caffeine containing foods moderately can be a vitality of life. But, a long-term intake or overdose of caffeine can result in many side effects. For example, headache, irritability, restlessness, hypertension, fetal abnormality, etc. Therefore, it is desirable that caffeine intake is under 300-400mg per day. To decrease intake of caffeine, 1. Use decaffeinated coffee 2. Product of decaffeinated coffee bean through gene transformation 3. Indicate content and function of caffeine on caffeine-food container 4. Provide an information of caffeine to public.

  • To examine pollen preparations which are being sold as a health food, one of these pollen tablets and one of the capsules were selected and investigated by microscopy. It was shown that the pollen coat which can act as a potent allergen was not removed and that the tablets contained other impurities. The results suggest that they are not safe as a food and that they may cause systemic allergy to certain persons. On the contrary, the pollens of the capsule preparation did not have the pollen coat and, therefore, have a less risk of causing allergy.

  • Solid dispersions were used to increase the dissolution rate of biphenyl dimethyl dicarboxylate (DDB) in water, with the ultimate goal of optimizing its bioavailability when incoporated into pharmaceuticals. Carriers used were Kollidon 30, Kollidon VA 64, 2-hydroxypropyl-${\beta}$-cyclodextrin (HPCD), sodium salicylate or sodium benzoate. DDB solid dispersions were prepared at drug to carrier proportions ranging from 1 : 5 to 1 : 20 (w/w) by solvent evaporation method. DDB tablets (7.5 mg) were prepared by compressing the powder mixture composed of solid dispersions, lactose, corn starch, crospovidone and magnesium stearate using a single-punch press. DDB capsules (7.5 mg) were prepared by filing the mixture into empty hard gelatin capsules (size #1). Dissolution studies of DDB from powdered solid dispersions, tablets and capsules were performed in 900 $m\ell$ of water at 100 rpm and 37$^{\circ}C$ by the paddle method. The dissolved amount was assayed by HPLC and expressed as the mean(%)of three determinations.

  • Matrix tablets of nifedipine (NP) were prepared with Eudragit, diluent (lactose or Ca. phosphate) and Mg. stearate employing two different preparation methods (wet granulation and direct compression) to develop its sustained-release dosage forms. The effects of various formulation factors on the dissolution rate of the drug were investigated. Dissolution test was studied in pH 6.8 phosphate buffer containing 1% sodium lauryl sulfate using the paddle method. Formulation factors were the type and content of Eudragit, the type of diluent and the tablet preparation method. The optimum formula of NP matrix tablet, which resulted in a similar dissolution profile to that from Adalat Oros used as a reference, was 30 mg NP, 10% Eudragit RS, 2% Mg. stearate and an adequate quantity of lactose to yield 500 mg weight using the wet granulation method.
