  • CYP1B1 enzyme metabolize PAHs and estradiol. CYP1B1 metabolize estradiol to 4-hydroxyestradiol that is considered as carcinogenic metabolite. Luciferase activity was induced about 20 folds over that control by 1 nM TCDD (2,3,7,8-tetrchlorodibenzo-p-dioxin) and these inductions were dose-dependent. Recent industrialized society, human hasbeen widely been exposed to widespread environmental contaminants such as PAHs (polycyclic aromatic hydrocarbon) that are originated from the incomplete combustion of hydrocarbons. PAHs are known to be ligands of the AhR (aryl hydrocarbon receptor). Induction of cytochrome P4501B1(CYP1B1) in cell culture is widely used as a biomarket for PAHs. Therefore we have studied the effect of PAHs in the human breast cancer cells MCF-7 to evaluate bioactivity of PAHs. Cytochrome P4501B1(CYP1B1) is known to be inducible by xenobiotic compounda such as policyclic aromatic hydrocarbon (PAH) and dioxins such as 2,3,7,8-tetrachloro-dibenzo-p-dioxin(TCDD). And these induction of CYP1B1 is also regulated by many categories of chemicals. In order to investigate the effects of several chemicals on CYP1B1 gene expression in luciferase gene, and then transfected into these cells. After treatment of chemicals, the luciferase activity was measured. We examined effects of PAHs on the CYP1B1-lucifrease reporter gene and CYP1B1 mRNA level. Benzo(k)fluoranthene showed strong response to CYP1B1 promoter activity stimulation, and also CYP1B1 mRNAs increase in MCF-7 cells in a concentration-dependent manner. flvonoids such as genistein decreased B(k)F induced luciferase activity at low concentration. it exhibited stimulatory effect at high concentration.

  • Measurement of estrogen concentration in bio-samples are very important for differential diagnosis of various disease or evaluation of health status. However, it is difficult to collect immediate data of estrogen concentration because they are measured by radioimmunoassay or chromatography which need time- and cost-consuming sample pre-treatment. This study was performed for development of new estrogen biosensor employing taste principles, and for evaluation of cross reactivity between various steroid hormones. Gene sequence of ligand binding domain of ${\alpha}$-human estrogen receptor (amino acid 302-553; hER-LBD) was cloned from human breast cancer cell line. The proteins of hER-LBD were produced by T7-E.coli expression system, and isolated by chromatography. hER-LBD were coated on the gold plated quartz crystal (AT-cut 9MHz), and resonance frequencies were measured by universal frequency counter. Estradiol, progesterone, testosterone, and aldosterone were used for cross reactivity of the hER-LBD. We also monitored influences of pH change in resonance frequency. The resonance frequencies of hER-LBD coated quartz crystal were decreased during increase of estrogen concentration from $15 \;{\mu}g/mL$ to $50\;{\mu}g/mL$. However, similar steroid hormones, progesterone and aldosterone, did not elicit the change in resonance frequency. Testosterone evoke weak change in resonance frequency. The new estrogen biosensor was more sensitive in pH 7.2 than in pH 7.6. These results suggest that hER-LBD coated quartz crystal biosensor is a probable estrogen biosensor.

  • Tamoxifen citrate is an anti-estrogenic drug used for the treatment of breast cancer. It showed a degree of hepatic carcinogenesis, when it used for long term as it can decrease the hexose monophosphate shunt and thereby increasing the incidence of oxidative stress in liver rat cells leading to liver injury. In this study, a model of liver injury in female rats was done by intraperitoneal injection of tamoxifen in a dose of 45 mg/kg body weight for 7 successive days. This model produced a state of oxidative stress accompanied with liver injury as noticed by significant declines in the antioxidant enzymes (glutathione-S-transferase, glutathione peroxidase and catalase) and reduced glutathione concomitant with significant elevations in TBARS (thiobarbituric acid reactive substance) and liver transaminases; sGPT (serum glutamate pyruvate transaminase) and sGOT (serum glutamate oxaloacetate transaminase) levels. The oral administration of dimethyl dimethoxy biphenyl dicarboxylate (DDB) in a dose of 200 mg/kg body weight daily for 10 successive days, resulted in alleviation of the oxidative stress status of tamoxifen-intoxicated liver injury in rats as observed by significant increments in the antioxidant enzymes (glutathione-S-transferase, glutathione peroxidase and catalase) and reduced glutathione concomitant with significant decrements in TBARS and liver transaminases; sGPT and sGOT levels. The administration of DDB before tamoxifen intoxication (as protection) is more little effective than its curative effect against tamoxifen-induced liver injury. The data obtained from this study speculated that DDB can mediate its biochemical effects through the enhancement of the antioxidant enzyme activities and reduced glutathione level as well as decreasing lipid peroxides.

  • Breast milk is general term for crude milk and mature that is secrete after two-three days of delivery. Because amount of milk secretion is different, disorder of milk secretion is to be classified into galactostasis and spontanous flow of milk. According to this point, we considered thirty four papers and got the conclusion about the concept, cause, therapeutic method and medication of secreation disorder. Therefore we report the result. galactostasis due to deficiency of the qi and blood, depression of liver qi, blood stasis of postpartum, excessiveness and so on. If the qi and blood is deficient, therapeutic method is enriching qi and benefiting blood, if the liver qi is deprssive, treatment is relieving the deprssive liver and regulating the circulation of qi. The milk is flowing spontanously and continously due to a prosperous condition of qi and blood, too deficiency of the qi and blood, depression of liver qi and so on. If the qi and blood is deficient, therapeutic method is tonifying and arresting the qi and blood, if Liver channel is stagnated fire, puring the liver of pathologic fire, relieving the deprssive liver and regulating the circulation of qi.

  • Houttuynia cordata Thunb, well known as 'E-Sung-Cho' in Korea, is traditional medicinal plant generally used in Oriental medicine therapy. We previously reported that the water extract of H. cordata inhibited cell proliferation and induced apoptosis in human breast carcinoma cells. In the present study, we investigated the biochemical mechanisms of anti-proliferative effects by the methanol extract of H. cordata (MEHC) in human lung carcinoma A549 cells. It was found that MEHC could inhibit the cell growth in a dose-dependent manner, which was associated with morphological change and apoptotic cell death as determined by formation of apoptotic bodies, DNA fragmentation and increased populations of apoptotic-sub G1 phase cells. Apoptosis of A549 cells by MEHC was also connected with a down-regulation of anti-apoptotic Bcl-2 and inhibitor of apoptosis proteins (IAPs) expression. MEHC treatment induced the proteolytic activation of caspase-3, caspase-8 and caspase-9, and a concomitant inhibition of poly(ADP-ribose) polymerase (PARP), ${\beta}$-catenin and phospholipase (PLC)-${\gamma}$1 protein expression. Taken together, these findings provide important new insights into the possible molecular mechanisms of the anti-cancer activity of H. cordata.

  • Objectives: The purpose of this study is to analyze the domestic study trends of pharmacopuncture therapy on obstetrics and gynecological diseases in Korean literature, through reviewing the clinical and experimental studies. Methods: We searched for clinical and experimental studies using pharmacopuncture therapy on obstetrics and gynecological diseases, published from January 2000 to May 2019, through 5 Korean databases. The study design, target disease, type of pharmacopuncture, method of intervention, and study results were analyzed. Results: 36 experimental studies and 15 clinical studies were finally included according to inclusion and exclusion criteria. In experimental studies, there were 12 studies about postmenopausal osteoporosis, 9 studies about obesity, 4 studies about endometriosis, 3 studies about hemostatic effects and analgesic anticoagulative effects, 2 studies about ovarian function, and analgesic antiphlogistic anticoagulative effects, and 1 study about menopausal symptoms. In clinical studies, there were 3 studies about obesity, postpartum disorders, dysmenorrhea, and women's urologic disease, and 1 study about menopausal symptoms, atypical squamous cells of undetermined significance (ASCUS) and breast cancer. Various types of pharmacopuncture have been proved to have a therapeutic effect in each of those obstetrics and gynecological diseases. Conclusions: This study indicates that pharmacopuncture therapy could be a good treatment for obstetrics and gynecological diseases. However, more well-designed and high-quality clinical researches are needed in further studies, to prove the effectiveness and safety of pharmacopuncture therapy.

  • Background: The application of Kinesio tape (KT) has become an alternative treatment for the reduction of edema owing to its distinct characteristics that mimic skin behavior. Although many studies have found that KT application has a positive effect on edema related to breast cancer and rehabilitation following mandibular third molar surgery, there is little evidence to support the use of KT for musculoskeletal injuries. Objects: The purpose of this study was to review the literature related to KT application for reducing edema caused by musculoskeletal disorders. Methods: A literature search (July 2022) was performed on PubMed for articles published between January 2012 and June 2022. The following keywords were used: "Kinesio taping," "Kinesio tape," "swelling," and "edema," with different combinations and derivations. Only articles available in English were included in this study. Results: Among 68 identified studies, seven met our search strategy and criteria and were included in the literature review. Five of these studies investigated musculoskeletal disorders of the knee joint; two of them reported that KT application had a positive effect on edema measured using perimetry following total knee replacement and anterior cruciate ligament reconstruction. However, the KT application did not improve swelling in patients with acute lateral ankle sprains. Pediatric patients with acute proximal phalangeal joint sprain experienced a more significant improvement in the reduction of swelling than the group using a splint. Conclusion: This literature review found discrepant evidence to support using KT for edema control in musculoskeletal disorders. Further research is needed to determine the effectiveness of KT for controlling edema following musculoskeletal injuries.

  • Metastatic bone tumor is the most common bone tumor and 32.5% of all primary malignant tumors are eventually metastasize to bone. Metastatic bone tumor has been more frequently encountered disease in the orthopedic fields due to the greater longevity of life of the patients with primary visceral cancers by major advances in early detection, diagnosis, and surgical/radiotherapeutic/chemotherapeutic treatment of primary and metastatic lesions. Therefore, the epidemiologic data about the incidences and the patterns of bone metastasis is important. We reviewed 417 patients who were diagnosed and treated for metastatic bone tumor at Kosin University Medical Center from 1985 to 1993 to analyse the primary lesion, age and sex distributions, location of bone metastasis, patterns of metastasis according to the primary. The results were as follows : 1. The common origin of bone metastasis were lung(29.5%), stomach(15.3%), breast(11.3%), unknown(7.7%), cervix(5.3%), liver(4.8%) in order of frequency. 2. There were 251 men and 166 women and their mean age was 54.8 years and the peak age incidence was in 6th decades. Most cases(85.3%) were occured beyond 5th decades. 3. The preferred sites of metastatic deposits were spine(64.0%), pelvis(40.5%), rib(38.8%), femur(36.7%), skull(21.1%), humerus(13.9%), scapula(13.0%) in order of frequency. In the spine, thoracic(42.1%), lumbar(39.1%), cervical(13.2%), sacral(5.6%) vertebrae were involved in order of frequency. 4. Multiple bone metastases were more common(73.1%) than single metastasis(26.9%). 5. In the lung cancer, the peak age incidence was 6th decades, and the preferred sites of bone metastasis were spine, pelvis, femur. 6. In the stomach cancer, the peak age incidence was 6th decades, and the preferred sites of bone metastasis were spine, femur, pelvis. 7. In the breast cancer, the peak age incidence was 5th decades, and the preferred sites of bone metastasis were spine, rib, pelvis. 8. In the bone metastasis with unknown primary site, the peak age incidence was 7th decades, the preferred sites of bone metastasis were spine, femur, pelvis, and the common histologic types were adenocarcinoma and squamous cell carcinoma.

  • Purpose : Spine is one of the most common sites of the metastatic bone tumors. Conservative management such as chemotherapy or radiotherapy has been preferred in most cases. However, the neurologic deficit has not been usually improved, and the quality of life was poor. The purpose of this study was to show the efficacy of the surgical treatments for metastatic spinal tumors in terms of postoperative improvements of neurologic deficit and survival time. Materials and Methods : Authors have reviewed the literatures and analyzed 14 patients of metastatic spinal tumors who were received operative treatments between August 1991 and June 1999 at the our department of orthopaedic surgery. Results : The most frequent primary tumor was breast cancer in women and lung cancer in men. The thoracic region was the most common site. There was a preponderance of females over males, and the age ranged between 4th and 8th decade. The indications of surgical treatment comprised instability, progressive neurologic findings, resistance to radiotherapy, pathological fracture, long life expectancy( >6weeks), isolated metastasis and need for pathological diagnosis. The degree of preoperative neurological deficit might influence on the improvement of clinical symptoms after surgery. Conclusion : The surgical treatment reduced the neurological deficit and pain regardless of the operative methods. In the early stage of neurological deficit, the surgical treatment was important for better prognosis. Recently early active operative treatment was performed for metastatic spinal tumor to minimize the intractable pain and to prevent the progression of the neurologic deficit. Early intervention can improve the quality of life and long term survival.
