    The aim of this study was to investigate water samples collected in coastal areas of Southern Thailand in the years of 2005 and 2008 for their contamination by the protozoan parasites Cryptosporidium and Giardia. One hundred eighteen water samples of different origin were collected from six Tsunami affected southern provinces of Thailand in early 2005, and they have been analyzed using standardized methodology. Fifteen out of 118 samples (12.7%) were positive for Cryptosporidium spp. and nine (7.6%) positive for Giardia spp. Additional 42 samples from two same areas were examined 3 years later, in the early 2008. Five out of 42 (11.9%) samples were positive for Cryptosporidium spp., and three out of 42 (7.1%) were positive for Giardia spp.. Both protozoans were found in reservoir, river/canal, and pond waters. It appears no significant differences (p<0.05) between Cryptosporidium and Giardia (oo)cysts levels during the two monitoring periods; however, the number of the investigated areas and samples in the second period was significantly less than in the first period. This is the first description on Cryptosporidium and Giardia (oo)cysts in water sources of Thailand, and it suggests the need for water quality control in the interest of public health safety. © 2010 Springer-Verlag.

    The effects of sweet almond oil inhalation on brainwave activity
    (2021-01-01) Nida Nuiden; Vorasith Siripornpanich; Winai Sayorwan; Tewelde G. Foto; Chanida Palanuvej; Nijsiri Ruangrungsi; Chulalongkorn University; Rangsit University; Mahidol University; St. Theresa International College; Kanchanabhishek Institute of Medical and Public Health Technology
    Sweet almond oil is a fixed oil obtained from the kernel of Prunus dulcis (Mill.) D. A. Webb. It is widely used as a carrier oil, or a diluent of essential oils, in aromatherapy. In an A-B experimental study of essential oil inhalation that considered the applicability of sweet almond oil as a diluent, sweet almond oil was repeatedly administered to participants. This study aimed to investigate the effects of inhaling sweet almond oil at two different times on brain wave activity, using the A-B experimental design. Twenty-five healthy participants ranging from 20 to 35 years of age were recruited. Sweet almond oil was administered by inhalation to each participant twice, with a 7-day washout period in between treatments. The absolute powers of delta, theta, alpha, and beta brain waves were recorded using a Nicolet EEG v32. Results from the EEG recordings showed no significant differences between brain waves after both the first and second inhalations of sweet almond oil. In conclusion, sweet almond oil was found to be suitable for use as an essential oil diluent.
