    (2017) Limoncu M.E.; Balcıoğlu C.; Oyur T.; Zeybek G.; Zeybek U.
    OBJECTIVE: The human head louse Pediculus capitis has recently acquired resistance to commercially available insecticides, which has expanded the search concerning the pediculicidal activities of some herbal products. The present study aimed to assess the in vitro pediculicidal activities of volatile oils extracted from 10 medical plants raised in Turkey: Rosa damascena (red provins rose), Pelargonium graveolens (geranium), Lavandula angustifolia (lavender), Salvia triloba (salvia), Rosmarinus officinalis (rosemary; two different chemotypes), Citrus bergamia (citrus tree), Cymbopogon nardus (citronella), Citrus limonum (lemon), and Cymbopogon flexuosus (lemongrass).METHODS: Head lice obtained from school children in Manisa Province were initially grouped as adults and nymphs and were then kept under optimal conditions (temperature of 27°C and humidity of 50%). A pinch of hair and filter paper were placed in Petri dishes and seven adults and seven nymphs were separately put in Petri dishes. The extracts obtained from each volatile oil were dropped on the lice specimens.RESULTS: The active movement of the external (antenna and legs) and internal (midgut and intestine) organs of the lice was monitored and recorded starting from 5th min for 24 hours by 10 to 30 minutes intervals. The time of death was defined as the loss of active movement and cessation of intestinal activities of lice. The results were analyzed using Statistical Packages for the Social Sciences (SPSS) version 15.CONCLUSION: The results showed that the volatile oil of Rosmarinus officinalis (two different chemotypes) was more effective than the other oils.

    [Monthly distribution of intestinal parasites detected in a part of western Turkey between May 2009-April 2010-results of acid fast and modified trichrome staining methods].

    In this study, 5073 fecal specimens and cellophane tapes from patients were examined during the period of May 1, 2009-April 30, 2010 in the parasitology laboratory of the Ege University Medical School. Sticky tape test and ethyl acetate sedimentation methods, saline, iodine, modified kinyoun's acid-fast, Trichrome, modified Trichrome and giemsa staining procedures have been applied to the stool samples. After the macroscopic and microscopic examinations, 1138 (22.43%) intestinal parasites were determined. Cryptosporidium spp. (n=381; 33.47%), Blastocystis hominis (n=368; 32.33%) and Cyclospora spp. (n=187; 16.43%) were the three most common parasites obtained during the examination. The most commonly determined helminth was Enterobius vermicularis (n=33; 2.89%). Detection of Microsporidium spores in immununosuppressed patients showed also the importance of specific staining methods. Intestinal parasites are causing serious public health problems in our region.
