For the research of cytotoxic natural products, 50 medicinal plants were extracted with benzene and methanol, separately, and screened against L1210 cells. From the results(Table I), 6 samples showed cytotoxicity both in benzene and methanol extracts of 17 samples in benzene extracts and 3 samples in methanol extracts, respectively. Generally, the cytotoxicity exhibited high frequency (34%) in benzene extract but low frequency in methanol extract(6%), it meant that active cytotoxic components had less polarity. ED_50 values less than 10 ㎍/㎖ were observed in 17 medicinal plants.

This study was conducted to examine physical therapists' awareness of alternative medicine and their treatment. 250 physical therapists who were working in Daegu were selected as subjects of this study. Data were collected from February 21, 2000 to March 31, 2000. The results of this study are summarized as follows. 1. Among 218 respondents, 72.7% of them directly experienced alternative medicine. According to general characteristics of the respondents, 79.0% of them who were in thirties had experiences in alternative medicine. 83.3% of the respondents who had worked for above twenty years experienced alternative medicine and 90.0% of the respondents who were working in Oriental medical clinics had experiences in it. 79.8% of the respondents who had been married experienced alternative medicine and 88.4% of them who were Buddhists had experience in it. 2. The sources of information on alternative medicine were newspapers and broadcast (22.9%), seminars of related associations (22.5%), and Books (20.0%). 3. The respondents experienced alternative medicine for the purpose of treating their chronic diseases (67.0%), improving their energy and quality of life (20.5%), and improving their weak physical constitution (13.4%). 4. According to the respondents' trust in alternative medicine, 40.8% of them trusted chiropractic, while 25.2% of them trusted massage and finger-pressure therapy. 19.7% of them trusted taping therapy and 15.1% of them trusted sports massage. 5. 67.0% of the respondents treated patients by alter native medicine in the hospitals and clinics. In the case of treatment methods by alternative medicine, 35.3% of them gave patients the massage and finger-pressure. 33.0% of them adopted taping therapy and 24.3% of them tried to treat patients by chiropractic. 17.0% of them applied moxacautery, while 15.1% of them gave patients the sports massage. 6. The respondents adopted alternative medicine to treat following diseases: lumbago (57.5%), shoulder pain (51.8%), sciatica (39.9%), arthritis (36.2%), headache (31.1%), hypertension (24.3%), diseases of the peripheral nervous system (22.4%), diseases of digestive organ (14.6%), insomnia (12.3%), obesity (8.7%), stroke (5.5%), allergy and skin diseases (4.1%), cystitis (3.6%). 7. According to their motives of concern about alternative medicine, 59.1% of them were interested in it because they expected additional effect which could be obtained from it in parallel with Western medicine. 16.7% of them were concerned about alternative medicine because they lacked ability to solve patients' clinical problems, while 15.3% of them were interested in it because they acknowledged the effect of it. 8.9% of them had interest in alternative medicine because they were dissatisfied with medical and scientific approach of Western medicine. 8. 73.4% of the respondents thought that alternative medicine needed to be introduced in the college/university curriculum

Background: In February 2020, a coronavirus disease 2019 (COVID-19) outbreak was reported in fitness centers in Cheonan, Korea. Methods: From February 24 to March 13, an epidemiological investigation was conducted on the fitness center outbreak. All those who were screened were tested for severe acute respiratory syndrome coronavirus-2 (SARS CoV-2) using real-time reverse transcriptase polymerase chain reaction. Contacts were traced and self-isolated for 14 days. We determined the epidemiological characteristics of confirmed cases of SARS-CoV-2 infection, and estimated the time-dependent reproduction number to assess the transmission dynamics of the infection. Results: A total of 116 cases were confirmed, and 1,687 contacts were traced. The source cases were 8 Zumba instructors who led aerobics classes in 10 fitness centers, and had the largest average number of contacts. A total of 57 Zumba class participants, 37 of their family members, and 14 other contacts were confirmed as cases. The attack rate was 7.3%. The contacts at Zumba classes and homes had a higher attack rate than other contacts. The mean serial interval (± standard deviation) were estimated to be 5.2 (± 3.8) days. The time- dependent reproduction number was estimated to be 6.1 at the beginning of the outbreak, but it dropped to less than 1, 2 days after the epidemiological investigation was launched. Conclusion: The results suggest that the COVID-19 outbreak was effectively contained with rigorous contact tracing, isolating, and testing in combination with social distancing without a lock-down.

The ovary undergoes substantial physiological changes along with estrus phase to mediate negative/positive feedback to the upstream reproductive tissues and to play a role in producing a fertilizable oocyte in the developing follicles. However, the disorder of estrus cycle in female can lead to diseases, such as cystic ovary which is directly associated with decline of overall reproductive performance. In gene expression studies of ovaries, quantitative reverse transcription polymerase chain reaction (qPCR) assay has been widely applied. During this assay, although normalization of target genes against reference genes (RGs) has been indispensably conducted, the expression of RGs is also variable in each experimental condition which can result in false conclusion. Because the understanding for stable RG in porcine ovaries was still limited, we attempted to assess the stability of RGs from the pool of ten commonly used RGs (18S, B2M, PPIA, RPL4, SDHA, ACTB, GAPDH, HPRT1, YWHAZ, and TBP) in the porcine ovaries under different estrus phase (follicular and luteal phase) and cystic condition, using stable RG-finding programs (geNorm, Normfinder, and BestKeeper). The significant (p < 0.01) differences in Ct values of RGs in the porcine ovaries under different conditions were identified. In assessing the stability of RGs, three programs comprehensively agreed that TBP and YWHAZ were suitable RGs to study porcine ovaries under different conditions but ACTB and GAPDH were inappropriate RGs in this experimental condition. We hope that these results contribute to plan the experiment design in the field of reproductive physiology in pigs as reference data.
