  • Narcotic drugs generally refer to serious and habitual hidden rash such as opium, heroin, methyphetamin, nabinol, cocaine, and so forth. At present, narcotic drugs are spread unchecked and are causing a big social problem. So many countries and narcotists are making every effort to set up a barricade against narcotic drugs. And there is a limit suitable treatment for them. Thus Tuo Yin Tang Jiang is developed. As indicated by Chinese letters, Tuo Yin Tang Jiang(TYTJ) is a crude drug. It is a traditional chinese medicine developed by the study done from June in 1998 to June in 1999 that Hubeisheng was entrusted with by People's Republic of China. This study is a treatise on etiology and syntomatology of narcotism. TYTJ is a medicine which is in accord with Pharmacopeia of the People's Republic of Chinal) in order to remove from the body the toxic materials resulting from narcotic drugs such as opium and heroin. According to the standard diagnosis on narcotism, 105 cases are studied and treated at the Rehabilitation Center attached to Enshi Autonomous Region Hospital in Hubeisheng. 105 cases are divided into 2 groups by double-blind method. One is the experimental group which has 56 cases. The other is the control group which has 49 ones.13 cases among 105 cases are addicted by intravenously injections. 9 cases are by oral takings. It took 10 days for this experiment to be performed. Two groups didn't show a striking individual variation based on the age, gender, period of taking drugs, withdrawal symptoms, complication, and state of health. The experimental group had a higher effect of treatment than the control group had. TYTJ treats diseases effectively and has no side effect, irrespective of the serious or slight addiction to opium and morphine.

  • The purpose of this study was to determine the effect of IPBC(3-lodo-2-propynylbutylcarbamate) on dandruff caused by the anthropophilic fungus Malassezia furfur. The effects of IPBC on dandruff were examined by evaluating (a) the MIC value of IPBC using broth dilution method; (b) the remnant antimicrobial activity of IPBC containing shampoo on skin disc; (c) the antidandruff efficacy of 1.0 % IPBC containing shampoo in double blind clinical trial. To investigate the remnant antimicrobial activity of IPBC against Malassezia furfur, guinea pig-skin disc was washed with antidandruff shampoo and then the diameter of inhibition zone per disc was measured. For clinical trial, thirty healthy volunteers, aged 25-35, participated in 4 week study. At 0, 2, 4 weeks, examinations of scaling, itching on scalp were carried out. The MIC(Minimun Inhibition Concentration) values of IPBC range from 0.10 to 1.00${\mu}g/ml$ and it seems that IPBC is more effective in the MIC values than zinc pyrithione, selenium disulphide, piroctone olamine and comparable to ketoconazole, climbazole. When the remnant antimicrobial activity of IPBC shampoo on skin disc was determined, 0.5% IPBC shampoo and 2.0% Ketoconazole shampoo resulted in similar antimicrobial effect. In addition, 1.0%, 2.0% IPBC shampoo was more effective than 2.0% ketoconazole shampoo. After two and four-weeks of 1.0% IPBC shampoo treatment, there was significant reduction of scaling, itching in test group compared to control group. On the basis of these results, it can be concluded that 1.0% IPBC is more effective than 2.0% Ketoconazole in reducing dandruff. It seems that strong capacity of drug binding to the stratum corneum plays a role in its antidandruff effect since adsorption of active ingredients on scalp is very important factor in reducing dandruff.

  • Objectives : This study mean to confirm the antibacterial activity of a garlic extract widely culturing in our region and was to determine the effect of dentifrice containing 0.1% extracts of garlic on dental plaque and gingivitis in a double blind and clinical studies in 50 healthy adults aged from 20 to 22 years who provided a consent for their participation. Methods : The antibacterial activity was evaluated using triple distilled water and the Kirby-Bauer disk diffusion method and the minimal inhibitory concentration(MIC) against various pathogens for periodontal disease, such as P. gingivalis 381(ATCC33277), was estimated. The experimental groups classified according to the concentration of garlic extract used: 10,000ppm(A), 5,000ppm(B), 2,500ppm(C), 1,000ppm(D). Oral examination of subjects was performed through clinical periods and on day of baseline, 6, 12, 19, 25 days plaque index and gingival index were scored by Turesky' modified index and Loe & Silness index. After 12, 19, 25 days use of their respective dentifrices, statistically decreases of plaque index, gingival index were shown in both the experimental and the control group, respectively. Results : There was significant antibacterial activity in the "2,500ppm(C)" group against P. gingivalis 381. Experimental group exhibited significantly the lower plaque levels and the higher levels of gingival health by the use of the dentifrices contained extract of garlic from 6 days compare with control group(p<0.05). The degree of decrease was more significant on gingivitis level of the experimental group than the control group(p<0.05). Conclusions : This findings indicated that the oral products containing a garlic extract is effective in preventing and treating periodontal diseases, and has potential value in inhibiting periopathogens.

  • Purpose: Impaired intestinal mucosal integrity may affect the gastrointestinal function, especially in relation to nutrition, absorption, and barrier function. The purpose of this study was to measure the prevalence of impaired intestinal mucosal integrity in presumed healthy children aged 1-3 years and assess the effects of zinc, glutamine, fiber, and prebiotic supplementation in them. Methods: A cross-sectional study was conducted in 200 children aged 1-3 years in Pasar Minggu, South Jakarta, Indonesia. A randomized double-blind parallel group method clinical trial was then performed to assess the effects of zinc, glutamine, fiber, and prebiotic supplementation. Results: Elevated calprotectin was found in 91/200 subjects (45.5%) at the onset of the study. After 10 months, 144 subjects completed the study: 72 subjects received the trial formula, whereas the other 72 received the standard formula. A transitory decrease in fecal calprotectin (FC) was observed after 6 months in the subgroup with normal FC levels, who were fed the test formula (p=0.012). Conclusion: The prevalence of impaired intestinal mucosal integrity in this group of Indonesian children aged 1-3 years was high. Supplementation with zinc, glutamine, fiber, and prebiotics during 6 months reduced FC only in those who had low levels at baseline but not in those with impaired integrity.

  • Background: Preemptive analgesia is an antinociceptive treatment that prevents the establishment of altered central processing which amplifies postoperative pain. A controversy exists over the effectiveness and clinical value of preemptive analgesia. We studied whether epidural bupivacaine and fentanyl prior to surgery could possibly affect postoperative pain and analgesic demands, as compared to administration of same at end of surgery. Methods: Forty patients scheduled for lower abdominal surgery were randomly assigned to one of two groups and prospectively studied in a double-blind method. Group 1(n=20) received epidural injection of 15 ml bupivacaine 0.25% with fentanyl 100 y g before surgery while group 2(n=20) received the same injection at the end of their surgery respectively. Postoperative analgesia consisted of basal plus patient-controlled mode of epidural bupivacaine and fentanyl from PCA system. Postoperative visual analog pain scores(VAPS), analgesics consumption, supplementary analgesics requirement and side effects were assessed for 3 postoperative days. Results: There were no significant difference in analgesics requirement and pain scores, at any time, during rest or after movement, in measurement between the groups. Conclusions: We conclude no clinical value of effectiveness in administering epidural bupivacaine-fentanyl before surgery as compared to administration after surgery.

  • Background: The incidence of pain on injection of propofol varies between 30 and 100%. A variety of pretreatments have been tried to alleviate this problem such as a local anesthetics, cooling and opioids. However, none of these pharmacological maneuvers were satisfactory yet. In a recent study, subhypnotic doses of both thiopental sodium and propofol decrease the acute pain. We report a comparison of thiopental sodium, lidocaine and placebo on the incidence and severity of pain on injection of propofol. Method: A controlled, double-blind study was performed to compare the prior administration of intravenous saline 2 ml(n=30, group S), lidocaine 20 mg(n=30, group L) and thiopental sodium 50 mg(n=30, group T) in alleviating the pain by propofol. Injection pain was assessed with the four-point verbal categorical scoring system. Result: The incidence of injection pain during induction was lower in group L(30%) and T(17%) than group S(77%). The incidence of injection pain was lower in group T(17%) than group L(30%), but not significant statistically. The pain scores for recall of pain in the recovery room was simlar to those pain during propofol induction. Conclusion: The pretreatment of thiopental sodium can be effective in reducing both incidence and severity of propofol injection pain and has similar effect to lidocaine to prevent propofol injection pain.

  • Osteoporosis is defined as a pathologic condition in which there occurs no change in the chemical composition of the bone, while bone resorption is abnormally increased. This compares with osteogenesis, which leads to a decrease in the amount of bone. Though many varieties of therapies have been tried, no fully effective method has been found. Korean red ginseng is an important variety of Korean ginsengs and many studies have been performed to investigate its effectiveness. But there has been no report on red ginseng's effects on osteoporosis. The purpose of this study was to determine the clinical effects of Korean red ginseng on postmenopausal osteoporosis patients. The study was designed as a double-blind study. Group I consisted of 30 postmenopausal osteoporosis patients who were administered red ginseng extracts and 15 patients who were administered maltose capsules, were included in group II. The following results were obtained after one-year administration to both groups. 1. There were no significant differences in the degree of wedging, number of compression fractures in the vertebral body, trabeculations, and Cobb's angles between the experimental and control groups. 2. Even though bone mineral density increased in the lumbar spine, and decreased in the femur, there was no significant statistical difference. 3. The serum levels of parathyroid hormone (PTH), calcium, phosphate, and alkaline phosphates showed no difference between the two groups regardless of treatment. 4. Urine Deoxy-pyridinoline (DPYD) decreased in the red ginseng group while it increased in the maltose group, but statistically there was no significant difference between the two groups. 5. The clinical presentations showed no significant differences using Visual Analog Scale. 6. The specific complications related with the long-term use of red ginseng did not occur in all patients. In conclusion, there were no statistically significant differences in clinical presentations, biochemical, and radiological studies between the red gins eng and maltose groups. No definite effectiveness of red ginseng on patients with osteoporosis was found.
