In 1991, Obesity rate of South Korea has reached to 18.7%. Because of economical development, the pattern of diet is exchanged from carbohydrate to rich protein and fat. The more problem is not only obesity of adult but also one of little child. Obesity is induced to diabetes mellitus, hypertension, artherosclerosis, hyperlipoidemia. heart and C.V.A disease, etc. In Woman, special important ploblem is the complex of beauty about Woman's figure. In Oriental Medicine, the factor of obesity is mainly regarded as dampness. And there are many treatments and methods to body weight loss, but obesity patients dislike to use them because of their side effects and inconvenience, intolerance. Now ear acupuncture is applied on so many disease because of its easy handly, non-side effect and high efficiency in clinics. Here obesity acupuncture is used to ear and whole body acupuncture. Because they react eachother for lack point. Therefore, in order to investigate the effect of obesity acupuncture and develop non-drug, non-starvation etc, we analyzed 453 the cases of body weight loss patients treated with ear and whole body acupuncture in Oriental Medicine Hospital of Jeon-Ju Woo-Sug University from April.1.1992. to March.17. 1993. The results were summarized as follows. 1. Distribution of sex ; male (4.4%), Female(95.6%) 2. Distribution of age in descending order ; 30s, 20s, 40s, 10s, 50s, below 10s, abowe 60s. The 20s-30s are group made up 60.7% of the group. 3. Distribution of occupation in descending order; housewife, student, service, salaried, merchant, teacher, farmer, inoccupation. 4. Distribution of human coporal constitution in descending order : Tae-Eum-In, So-Eum-In, So-Yang-In. 5. Distribution of body height and weight, 155-164cm ; 71.1%, 60-70kg, 74.6% are majority. 6. Distribution of weight variation, 2-6kg(71.0%) is majority, also 13-14kg(0.4%). 7. Distribution of duration in descending order ; 1-3 years, 3-6 years, 1-12months, above 10 years but in success, 1-12 months, 1-3 years, 3-6 years, above 10 years. Therefore, we know that the shorter duration of obesity is, the more loss of body weight. 8. Past experiences to body weight loss; Yes(69.5%), No(30.5%). The success rate accordant with the past temporary experiences shows that the cases without experience is higher than the ones with experience. 9. In distribution of times(treatments), 10 times is top. The rate of body weight loss is the highest in 14 times. Therefore, I think that one would need at least 10 times. in order lose body weight 10. Distribution of body weight variation in treatments times is at 2 times(3-4kg loss), and surprisingly is 14kg loss at above 15 times. 11. Distribution of symptoms improvement, in descending order ; heavy sense in body, dec. of appetite, inc.of exercise, lumbago, edema, knee pain, inc.of urine, inc. of fullness sense, thirsty, disease of gynecology, white tung, chest burning, heart burning, dec.of tobacco, drink taste. motion sickness, allergy, water eczema, arthma, belching. 12. Distribution of snack; Yes(87.4%), No(78.6%) 13. Distribution of exercise; Yes(21.4%), No(78.6%) 14. Distribution of sleeping times, above 7 hours(79.0%) 15. Distribution of the reason to body loss, the complex of beauty(68.7%) is top. 16. Distribution of side effect in obesity acupuncture, constipation (17.4%) is top. 17. Distribution of method in body weight loss ; dietary treatment (31.1%), sauna(26.7%), exercise(19.7%), the center of body weight loss (15.0%) herb-med and starvation treatments (5.1%), hand-finger acupuncture (hand-foot acupuncture) is 1.6%, diet pill(0.3%), etc(0.6%).

This study sought to investigate the distribution, antimicrobial resistance rate, and bacterial co-infection frequency of non-tuberculous mycobacteria (NTM) in a single center in Incheon, South Korea. A total of 8,258 specimens submitted for tuberculosis (TB)/NTM real-time PCR tests during the years 2015 to 2020 were retrospectively reviewed. In total, 296 specimens (3.6%) were NTM positive, and the positivity increased from 2.5% (30/1,209) in 2015 to 3.8% (66/1,740) in 2020. Of 296 NTM specimens, 54.7% (162/296) were identified as the Mycobacterium avium complex (MAC) followed by the Mycobacterium abscessus complex (MABC) 20.9% (62/296), M. fortuitum 6.4% (19/296) and M. flavescens 3.4% (10/296). Of the NTM-positive specimens, 76.7% (227/296) were tested for drug resistance. The results showed multidrug-resistant NTM in 40.1% (91/227) and extensively drug-resistant NTM in 59.9% (136/227) of these specimens. Of the 145 isolates taken for bacterial culture, bacteria/fungi co-infection with NTM accounted for 43.4% (63/145), in which the most common bacterial species was Klebsiella pneumonia (23.8%, 15/63). This study is the first report on the distribution and antimicrobial resistance of NTM in Incheon. As the proportion of NTM infections increases, active treatment and thorough infection control are required for effective management.

The demand for biopharmaceuticals is on the rise spurred by the fourth industrial revolution and an aging society in Korea. Consequently, the scale of the biopharmaceutical industry is continuously increasing globally, thereby leading to an increase in the distribution of biopharmaceuticals. However, the relative inferiority of the domestic drug distribution structure, when compared to the advanced countries, and strict logistics regulations concerning the handling of biopharmaceuticals have raised the need for systematic management. Essentially, the significance of third-party logistics companies in the cold chain for pharmaceutical cold chain has increased with an intense management environment for pharmaceuticals. The purpose of this study is to investigate the selection factors of drug cold chain's third-party logistics companies and to examine the influence of selection factors on satisfaction. A multiple regression analysis was conducted to investigate how cold chain third-party logistics factors affect the satisfaction of third-party logistics in cold chain. The results of analysis showed that expertise, facility, and linkage are factors affect customer satisfaction. The managerial capacity was derived not as an influential factor. These findings suggest that the future cold chain industry will be equipped to provide direction and strategic implications.

O-carboxymethyl water-soluble chitosan (OCMCh) prepared for enhance the application of chitosan was modified with mthoxy polyethyleneglycol (mPEG) by ion-complex for long circulation in the blood. OCMCh-PEG-PLLs was prepared by forming ion-complex with OCMCh-PEG and Poly(L-Lysine) (PLL) for drug and gene delivery system. The physicochemcal characterisitcs of OCMCh-PEG-PLLs were investigated by FT-IR, $^1H$-NMR. These results showed that CMCh-PEG-PLLs were successfully syntehsized by ion-complex. Particle size distribution and zeta potential of the OCMCh-PEG-PLLs were determined using dynamic light scattering technique. Transmission electron microscopy (TEM) was also used to observe the morphology of the OCMCh-PEG-PLLs. OCMCh-PEG-PLLs have spherical shapes with particle size 290∼390 nm. OCMCh-PEG-PLLs were showed when the feeding amount of mPEG ratio was increased, particle size and zeta potential were decreased. Based on these results, it is possible to introduction of the OCMCh-PEG-PLLs into various biomedical fields such as drug and gene delivery system.

I examined and referred to literatures of every generations on the nicknames, causes, herb medications and acupucture treatments of ptosis(上胞下垂). And then the results were obtained as follows. We've compared and analyzed Occidental and Oriental medical causes, symptoms and treatments of Primary trigeminal neuralgia and wanted to get better effects by a cooperative analysis. So the examination and analysis of the recent treatment tendency and reference bibliography show the following results. 1. Trigeminal neuralgia is nerve systematic disease appearing in the distribution scope of trigeminal nerve. It's characterized by extreme pain accompanying with a repeated and simultaneous fit from several seconds to 1-2 minutes. 2. Though there are many hypothesis on the trigeminal neuralgia, but now many doctors agree that when trigeminal nerve is under the local out of sheath conditions resulting from receiving a chronic stimulus, and the nucleus of trigeminal nerve fire, owing to decrease of pain control function and abnormal occurrence of action potential, it would be appeared. 3. The Oriental medical name of trigeminal neuralgia is generally Dootong, Doopoong, Myuntong, Pyundootong, Pyundoopoong, and Myuntong is the nearest in Occidental medicine. 4. The Oriental medical cause of trigeminal neuralgia is usually divided into Wekam and Naesang. The first one is caused by Poonghan, Poongyul, Damhwa and wicked energy enter into the body, the mechanical energy is obstructed and can't move any more, so the pain appears by them. The other cause is the hurt by emotion. And it would be loss of the transportain of liver and obstructed, so result into Kanwulhwahwa, Kanpoongnaedong and the pain appears. 5. There are two methods of curing trigeminal neuralgia. As a medication, primary method is prescribing Carbamazepine and the second is using Phenytoin or Baclofen. And as a operation, Drug injection of trigeminal nerve, Amputation of branches of trigeminal nerve, Retrogasserian glycerol rhizotomy, Radiofrequency gangliolysis, Neurovascular decompression can be used. 6. There are several herb medicines for Trigeminal neuralgia. First, Chungung is good for Hwaejeetong, Keopoongjedam, Hwalhyuljeetong. Second, Jeongal, Jiryong, Okong is used for Sikpoonghekyung, Tongkyungjeetong. Third, Baekjee, Sesin, Cheonma, Manhyungja is efficacious in Sinonhepyo. Sanpoongjeetong. Fourth, for falling of liver's Wulhwa, Yongdamcho, Hyungge, Kukwha can be used. And also Saengjihwang, Hwangkm is good for going down the fever of Yangmyungwiyul and finally, Baekkangjam. Moryu can be effective for Jaumjamyang, Haekyungjitong. The other medicines can be used as assistant analgesics, and it also efficacious. 7. Generally the points of pain on the face and the points of Soyangkyung and Yangmyungkyung is used for Acupuntual therapy, because the two meridians passed on the face. Hakwan. Sabaek, Kwanryo, Keoryo, Hyubkeo, Taeyang, Jeechang, Younghyang, Eoyo, Chanjuk. Yangbaek. Sajukkong. Dooyoo, Kwangsangjum, Sengjang, Poongjee is used for taking near point and Joksamlee, Naejung, Habkok is used for taking distant point. 8. Dansam or Danggui injection which have a effect for Hwalhyulhwaeo, Sokyunghwalak and Vit B1, Vit B2, Vit B12, $2\%$ Hydrochloroprocaine, $1\%$ Lidocaine injection to pain point for local analgesics had so good effect. And external application and moxibustion are used for another treatment. 9. It proved that through mouse model, both Herb medication group and Drug medication group are efficacious for trigeminal neuralgia similarly and also the cooperative medication group shows more effective result than the only drug medication group.

Drug interactions with food, on occasion, lead to serious nutritional and functional changes in the body as well as alternations of pharmacological effect. It, therefore, should be necessary to take drug interactions with food into consideration for effective and safe therapeutics. Diabetes mellitus is a heterogeneous group of disorders characterized by abnormal glucose homeostasis, resulting in hyperglycemia, and is associated with increased risk of micovascular, macrovascular, and neuropathic complications. However, the precise mechanism of diabetes mellitus remains unclear. Three basic objectives in the care of diabetic patients are maintaining optimal nutrition, avoiding hypo- or hyperglycemia and preventing complications. The purpose of this study was to investigate thε effect of Laminaria japonica diet on the absorption, distribution, metabolism and excretion of glipizide which are frequently used in the treatment of diabetes. Diabetic rats induced by streptozotocin were employed in this study. Blood concentrations of oral hypoglycemic agents were measured by HPLC and resultant pharmacokinetic parameters were calculated by RSTRIP. The mechanisms of drug interaction with food were evaluated on the basis of pharmacokinetic parameters such as $k_{a},\;t_{1/2},\;C_{max},\;t_{max}$ and AUC. Administration of glipizide in normal rats treated with Laminaria japonica diet showed significant increase in AUC, $k_{a},\;t_{1/2},\;t_{max}$ and decrease in $C_{max}$, compared to those without Laminaria japonica diet. This might result from adsorption of glipizide on components of Laminaria japonica, causing delayed absorption. Administration of glipizide in diabetic rats treated with Laminaria japonica diet showed significant increase in $t_{1/2}\;and\;t_{max}$, and decrease in $C_{max}$, compared to those without Laminaria japonica diet. This might also result from adsorption of glipizide on components of Laminaria japonica, causing delayed absorption and flattened blood concentration of glipizide. The oral glucose test showed that Laminaria japonica diet could lower blood glucose level probably through either inhibiting the activity of disaccharidases, intestinal digestive enzymes, or delaying the absorption of glucose. More studies should be followed to fully understand pharmacokinetic changes of glipizide caused by long-term Laminaria japonica diet.

Previous Korean total diet studies (KTDSs) have estimated dietary exposure to toxic chemicals based on 110-120 representative foods selected from over 500 foods appeared in the Korea National Health & Nutrition Examination Surveys (KNHANES), which would result in a possible underestimation. In order to find measures for a closer-to-real estimate of dietary exposure to heavy metals, this study examined the feasibility of mapping foods to the representative foods in the KTDS by comparing estimates. In mapping, those foods not analyzed in the 2009 KTDS (443 out of 559 foods appeared in the 2007 KNHANES) were mapped to the 114 representative foods used in the 2009 KTDS based on the closeness in regards to biological systematics and morphological similarity. Dietary exposures to total mercury and lead were re-estimated using the content of total mercury and lead in 114 foods analyzed in the 2009 KTDS, food intake, and individual's own body weight for respondents in the 2007 KNHANES instead of mean body weight of Koreans used in the 2009 KTDS. The re-estimates of exposure with mapping were approximately 50% higher than the original estimates reported in the 2009 KTDS. In addition, mapping enabled the comparison of percentile distribution of the exposure among populations of different age groups. In conclusion, estimates via mapping resulted in a more comprehensive estimation of dietary exposure to heavy metals present in foods that Koreans consume.

Although, in human medicine, strains of methicillin-resistant staphylococi have become the most important causative agents of nosocomial infections, studies on the small animals are very. limited. The aim of this study was to determine mecA gene and susceptibility to antibiotics of staphylococci strains isolated from clinically ill or healthy dogs and cats, during the period August 2002-July 2003. A total of 136 staphylococci (87 coagulase-positive and 49 coagulase-negative) were investigated for antibiotic resistance, using disk diffusion and minimum inhibitory concentration (MIC) test. The mecA gene was detected using the polymerase chain reaction. The isolates belonged to the species S. aureus (53 isolates), S. intermedius (34 isolates), S. epidermidis (26 isolates) and other coagulase-negative staphylococci (CNS, 23 isolates). Of the 136 isolates, 43 (31.6%) were mecA-positive and the frequency of the ,presence of mecA gene varied among the different species. All S. aureus strains were mecA-negative and were found to be susceptible, with an oxacillin MIC $\leq$1 $\mu\textrm{g}$/ml. Five (13.6%) isolates of 36 that exhibited oxacillin resistance on the MIC testing were found to be mecA-negative, suggesting not all mecA-positive strains may be an oxacillin resistant. However, the mecA presence of the strains was correlated with high oxacillin resistance: 71.4% (10 isolates of 14; P < 0.001) for mecA-positive S. intermedius and 72.4% (21 isolates of 29; P < 0.001) for mecA-positive CNS isolates. About 69% (94 isolates of 136) showed resistance to at least one drug, and 22.8% (31 isolates) were resistant to four or more different drug classes. Resistance (36 isolates, 71.7%) to penicillin G was a common finidng. This study suggest that the mecA-positive staphylococci are prevalent in small animals, and selection of antibiotics to treat infections caused by mecA-positive staphylococci may be very limited because of multi-drug resistance.

Liposome as a carrier of topotecan (TPT), a promising anticancer drug, has been reported in attempt to improve the stability and antitumor activity of TPT. However, the biodistr ibution pattern of TPT liposome in vivo and PEG-modified liposome containing TPT have not been studied systemically. In this paper, the in vitro stability and in vivo biodistribution behavior of several liposomes containing TPT with different lipid compositions and PEG-modification were studied. Compared with the 'fluid' liposome (S-Lip) composed of soybean phosphatidylcholine (SPC), the 'solid' liposome (H-Lip) composed of hydrogenated soybean phosphatidylcholine HSPC decreased the leaking efficiency of TPT from liposome and enhanced the stability of liposome in fetal bovine serum (FBS) or human blood plasma (HBP). The results of biodistribution studies in S$_{180}$ tumor-bearing mice showed that liposomal encapsulation increased the concentrations of total TPT and the ratio of lactone form in plasma. Compared with free TPT, S-Lip and H-Lip resulted in 5- and 19- fold increase in the area under the curve (AUC$_{0\rightarrow\propto}$), respectively. PEG- modified H-Lip (H-PEG) showed 3.7-fold increase in AUC$_{0\rightarrow\propto}$ compared with H-Lip, but there was no significant increase in t$_{1/2}$ and AUC$_{0\rightarrow\propto}$ for PEG-modified S-Lip (S-PEG) compared with S-Lip. Moreover, the liposomal encapsulation changed the biodistribution behavior, and H-Lip and H-PEG dramatically increased the accumulation of TPT in tumor, and the relative tumor uptake ratios were 3.4 and 4.3 compared with free drug, respectively. There was also a marked increase in the distribution of TPT in lung when the drug was encapsulated into H-Lip and H-PEG. Moreover, H-PEG decreased the accumulation of TPT in bore marrow compared with unmodified H-Lip. All these results indicated that the membrane fluidity of liposome has an important effect on in vitro stability and in vivo biodistribution pattern of liposomes containing TPT, and PEG-modified 'solid' liposome may be an efficient carrier of TPT.

The control of the surface energy by electrohydrodynamic force provides electrospraying with various potential advantages such as simple particle size control, mono-dispersity, high recovery, and mild processing conditions. The advantages are quite helpful to improve the stability of protein drug and control its release. Herein, the nano-encapsulation of protein drugs using electrospraying was investigated. Albumin as a model protein was processed using uniaxial and co-axial electrospraying, and chitosan, polycaporlactone (PCL), and poly (ethylene glycol) (PEG) were used as encapsulation materials. The major processing parameters such as the conductivity of spraying liquids, flow rate, the distance of electrical potential gradient, etc were measured to obtain the maximum efficiency. In the chitosan systems, mean particles size decreases as flow rate and the distance between nozzle and the collecting part decreases. In the uniaxial technique of the PCL systems, mean particles size decreases as flow rate decreases. In the coaxial technique of the PCL systems, it was found that the particles size gets larger under the application of the higher ratio of inner-to-outer liquid flow rates. The primary particles formed out of an electrospraying nozzle showed narrow particle size distribution, but once they arrived to the collecting part, aggregation behavior was observed obviously. Efficient nano-encapsulation of albumin with PCL, PEG, and chitosan was conveniently achieved using electrospraying at above 12 kV.
