Folk remedies in Korean rheumatoid arthritis patients

BACKGROUD: A lot of "Folk Remedies" on rheumatoid arthritis treatment prevail in Korea, but they have never been evaluated or investigated systemically. Therefore we studied folk remedies used in rheumatoid arthritis patients. METHODS: We delivered 12 questionnaires to 106 rheumatoid arthritis out -patients of family medicine, internal medicine, and orthopedics, located in Seoul and Kyungki area. These questionnaires addressed to demographic characteristics, duration of rheumatoid arthritis, current treatments, kind of folk remedies experienced, decision to choose folk remedies and its subjective effects, and volition to try new folk remedies. RESULTS: There were up to 27 kinds of folk remedies used by 77 people (72.8% of total). Lower education level was proved to be correlated with folk remedies experience. Most patients began their remedies introduced by relatives or close friends (83.1%) . Many Patients on folk remedies were skeptical about its effect, but they were still willing to try new folk medicine (80.6%). Many rheumatoid arthritis patients experienced folk remedies and were skeptical about its effects, but they were still willing to try new folk medicine. Therefore, education on folk remedies is needed.

A Study on Hair Mineral Concentrations in Diabetic Patients

BACKGROUND: Minerals are essential nutrients of human body and related with various diseases. Some minerals may be associated with endocrine function. Especially, chromium is known to enhance the action of insulin. The correlation of minerals with DM has not been studied in Korea yet. Therefore, to know whether there is any significant difference of minerals concentration and component between DM patient and non-DM patient, the quantity of each mineral in the hair of patients and controls was measured. If there is any significance, a guideline of nutritional therapy with minerals could be proposed and recommended. METHOD: An analysis of hair was performed on the type II diabetic patients and non-diabetic patients who visited Severance hospital outpatient clinic from April, 2001 to January, 2002. Hairs were obtained from each subject and were analyzed into the concentration of mineral using an atomic absorption spectrophotometer. The concentration of each element between the two groups was compared by t-test analysis. RESULTS: The concentration of copper, sodium, chromium, sulfur, and antimony was significantly different; the level of copper was significantly lower in the diabetic group (P=0.013). On the other hand, the levels of sodium, chromium, sulfur, and antimony were significantly higher in the diabetic group (P=0.013, 0.0001, 0.010, 0.0001). CONCLUSION: Previous studies have suggested that the concentration of chromium in diabetic patients' blood was lower than those in normal population. However, this study showed that the measured amount of chromium in hair was significantly higher in the diabetic group. This result warrants a study on the correlation between the concentration of chromium in blood and hair, and also, on the mutual relationship of other minerals (copper, sodium, sulfur, and antimony) which also showed significant difference in this study.

Kinetic Analysis of Intracellular ionized Calcium Level from Human Peripheral Blood Lymphocytes Using Flow Cytometry / 대한임상병리학회지

BACKGROUND: Intracellular ionized calcium plays a central role in the transduction of external stimuli as a critical second messenger. The spectral properties of fluo-3 allows the analysis of intracellular ionized calcium level by flow cytometers. The aim of this study is to assess the performance of flow cytometer for measuring intracellular ionized calcium level using fluo-3 and to define the reference interval of intracellular ionized calcium level of lymphocytes from healthy people, and to find out the clinical implications according to various disorders. METHODS: For the analytical performance of flow cytometer on determining the concentration of intracellular ionized calcium, precision study, lowest limit of detection, analytical range, and the loading stability of fluo-3 were per foamed. Fifty-four cases of healthy people, 52 cases of renal transplant patients, and 20 cases of diabetes mellitus patients were included in this study. RESULTS: Loading effect of fluo-3 at room temperature was stable upto 5 hours. Lowest limit of detection of ionized calcium concentration was 4.34 nM at in-situ calibration procedure. Within-run and among-day intraindividual CVs of in-situ calibration procedure were 6.67% and 13.99% respectively, and of optical calibration procedure were 13.86% and 16.12% respectively. The reference interval of cytosolic free calcium level for healthy people ranged 73.54 - 155.09 nM without sexual differences. The level of intracellular ionized calcium was lowered by 36.9% on renal transplant group in comparison with healthy control group. But, level of cytosolic free calcium was Increased upto 276.0% on acute rejection group and 159.1% on diabetes mellitus group compared to control group. CONCLUSIONS: These results reveal that in-situ calibration method for intra cellular ionized calcium using flow cytometry with flue-3 can be regarded as an accurate and standardized method. Quantitation of intracellular ionized calcium level might be used as the monitoring test for early detection of acute rejection after renal transplantation.
