  • In order to investigate the effects of Kamikwakjeongtang by using the experimental animals. the action on gastrointestinal smooth muscles. the action of gastric juice secretion, the action of antiulcer. the transport ability of intestinal contents. the action of anticatharsis and the actions on the central nervous system were studied. The results were as follow: 1. Spontaneous motility of the isolated ileum of mice was suppressed and antiacetylcho-line chloride action was recognized. 2. Anti-action on barium chloride of fundus-strip of white rat was recognized. 3. Supression effects on gastric juice secretion. free acidity was recognized. 4. Preventive effect on the ulcer induced by pylorus-ligated was recognized. 5. Supression effects of large intestinal transport ability was recognized. 6. Anti-carthartic action was shown but was not recognized. 7. Analgesic effect by the acetic-acid method and prolonged effect of the total sleep time by pentobarbital-Na were recognized. According to the above results, effects based on oriental medical reference were consistent with the actual experimental effects.

  • Life Science Research Center of SK Chemicals has developed a 3rd-generation anticancer platinum drug for the first time in the nation′s 100-year-old pharmaceutical industry. The Korea Food and Drug Administration (KFDA) approved the sale of "Sunpla" (code name SKI 2053R, general name : Heptaplatin) on July 14, 1999 for the treatment of advance, metastatic gastric cancer. Cisplatin, the 1 st-generation anticancer drug, which was developed by Bristol-Myers of the United States in 1976, is one of the most potent anticancer drugs and is a major component of combination chemotherapy for a variety of human cancers. However its clinical usefulness has frequently been limited not only by undesirable side effects such as severe renal toxicity, nausea, vomiting, ototoxicity, and neurotoxicity but also by the development of resistance. Carboplatin, the 2nd-generation anticancer platinum drug, which was also developed by Bristol-Myers in 1986, has modified the problems of the renal and gastrointestinal toxicities of cisplatin. Carboplatin, however, has no enhanced therapeutic efficacy over cisplatin and does not possess the property to overcome cross-resistance to cisplatin.

  • Acebutolol is almost absorbed after oral administration, but its bioavailability is reduced because of considerable first-pass metabolism through the gastrointestinal tract and liver. The purpose of this study was to report the pharmacokinetic changes of acebutolol (15 mg/kg,oral) and its main metabolite, diacetolol in rabbits pretreated (15 mg/kg, oral) and coadministered (15 mg/kg, S. C., bid for 3 days) with diltiazem. The plasma concentration and area under the plasma concentration-time curves (AUC) of acebutolol and diacetolol were significantly increased in rabbits pretreated and coadministered with diltazem. The elimination rate constant ( $K_{el}$ ) and total body clearances (CL $_{t}$) of acebutolol and diacetolol were significantly decreased and half-life of those were significantly prolonged in the rabbit. Metabolite percentage rate of diacetolol to the plasma concentration of total acebutolol in rabbits pretreated and coadministered with diltiazem were significantly decreased. The results suggest that the dosage of acebutolol should be adjusted when the drug would be administered chronically with diltiazem in a clinical situation.n.

  • Gastric duplication is a rare anomaly which account for only 3.8% of all gastrointestinal duplication. Gastric duplications are usually cystic lesion without communication with lumen. Most frequent presentation is an abdominal mass with vomiting, mainly diagnosed within the first year of life. Surgical removal is necessary in all cases, and optimal timing for surgery is the time that diagnosis is made. However, prenatally diagnosed gastric duplication is getting more common, and determining timing for surgery is not easy due to absent or minimal symptoms just after birth. We experienced prenatally diagnosed gastric duplication in a female newborn baby that gastric duplication was suggested in $24^{th}$ week of gestational age through prenatal ultrasonogram. Surgical removal was done at 3 months after birth, and showed good results. We think that natural history of gastric duplication and prevalent age of surgical disease which is similar to gastric duplication such infantile hypertrophic pyloric stenosis should be considered when timing of surgery on prenatally gastric duplication is decided.

  • Sustained-release dosage form of ferruginous hematinics which can be absorbed effectively without forming "iron block" that caused by high concentration of Iron in the gastrointestinal tract, was studied. Gelatinized micropellets containing medicament were prepared according to the method of N. Tanaka et al. and hardened in 10% formalin-isopropanol in various time. Gelatinized micropellets were digested with artificial gastric juice and prepared a graph of iron concentration determined by Hong's method. As a result, it is assumed that gelatinized sustained-release dosage form can be a good ferruginous hematinics and it is shown that the preparation of 72-hour-hardening in 10% formalin-isopropanol has a suitable sustained release.d release.

  • A common belief is that human milk is sterile. However, the development of culture-independent molecular methods, especially Next Generation Sequencing, has revealed that human milk harbors diverse and rich bacterial communities. Although studies aimed at characterizing the microbiota of human milk have produced different findings, Staphylococcus and Streptococcus are presumed to be normal members of the microbiota. Factors that influence variation in the microbiota are unclear; however, the postpartum time, route of delivery, maternal obesity, and health status may be influential. The origin of the microbiota is a hotly debated topic. Human milk bacteria are thought to be introduced through bacterial exposure of the mammary duct during breast feeding and/or the entero-mammary pathway from the maternal gastrointestinal tract. Although the exact mechanism related to the entero-mammary pathway is unknown, it is presumed that bacteria penetrate the intestinal epithelium and then migrate to the mammary gland, dendritic cells, and macrophages. In this review, various relevant studies are introduced.

  • Cowden syndrome (CS), also known as multiple hamartomas syndrome, is a rare hereditary autosomal dominant disorder caused by a germline mutation in the phosphatase and tensin homolog (PTEN) gene mapped on chromosome 10. The clinical features of CS are variable, primarily presenting as mucocutaneous lesions (99%). A mucocutaneous lesion, such as trichilemmoma of the face or keratosis of the extremities, is an important diagnostic marker for CS. CS has been reported to increase the incidence of benign and malignant neoplasms in the breast, thyroid, and gastrointestinal tract. The risk of developing malignancy in individuals with CS is up to 10 times higher than general population throughout an entire life time.

  • Iron deficiency is the most common nutritional problem worldwide. Oral iron supplementation programs have failed because of noncompliance and gastrointestinal toxicity. The purpose of this study was to explore the possibility of alginate gel bead as an oral controlled release system of iron supplements and increase the stability of iron succinyl casein (ISC). Alginate beads containing ISC were prepared by the gelation of sodium alginate with calcium cations. The release profiles of ISC were investigated according to the concentration of polymer, the drug/sodium alginate ratio, the concentration and type of cation, curing time and pH of calcium chloride solution.

  • Ingestion of foreign bodies (FBs) is a common phenomenon among young children. Plain radiography is the first step diagnostic modality to detect the radio-opaque FBs. And computed tomography has been recommended by several guidelines as useful modalities for diagnosing ingested FBs. However, there is a risk of radiation exposure, making it burdensome to use in asymptomatic patients. Ultrasound (US) is not a commonly used technique for diagnosing ingested foreign bodies. However, US can provide real-time imaging with good resolutions without radiation exposure in pediatric patients. Herein, we report two pediatric cases of metallic foreign body ingestion that were successfully diagnosed using US for localizing foreign bodies. This study indicates that US may be used as an alternative method for detecting the localization of metallic foreign bodies in the gastrointestinal tract without exposure of radiation, particularly in pediatric patients.
