Identification of lxodid tick species on livestock in two districts, viz., D.I. Khan and Lakki Marwat of Northern Pakistan were made during the period from March to November 2009 through animals' survey and questionnaire. The main tick species were Amblyomma (14.3%), Boophilus microplus (l 8.5%) and Hyalomma anatolicum and H. dromedarii (67.2%). Out of 3009 collected ticks, the highest number of female (88.7%) and the lowest of males ( l 1.3%) belong to Boophilus; the lowest number of female (92.4%) and the highest of males (77.5%) belong to Amblyomma. However, cows were more susceptible than buffaloes and camels ranked third to ticks infestation. Moreover, cows, buffalos, goats and sheep harbored mixed infestation (had more than one type of ticks), however, camels and donkey harbored single infestation (had only one type of tick). An emerging ethno-veterinary or traditional remedy is poultry keeping for ticks' elimination in Lakki Marwat. The results of this research will be helped in taking appropriate measures to reduce tick infestation and to improve management practices. Hence, it will help to increase farm productivity and farmers income. 相似文献

A highly reproducible and efficient in vitro shoot regeneration system was developed in a potential medicinal plant, Albizia lebbeck using root explants. Root explants from 15 day-old-aseptic seedlings were cultured on Murashige and Skoog (MS) medium supplemented
with different concentrations (0.5, 2.5, 5.0, 7.5 and 10.0 μM) of 6-Benzyladenine (BA), Kinetin (Kn), 2-Isopentenyl adenine
(2-iP) singly as well as in combination with α-Naphthalene acetic acid (NAA) (0.1, 0.5, 1.0, 1.5 and 2.0 μM). The highest
rate of shoot multiplication (16.0 ± 1.87 for the average shoot number and 5.16 ± 0.38 cm for shoot length) was achieved on
MS medium supplemented with 7.5 μM BA and 0.5 μM NAA. The effects of medium type, medium strength, pH and subculture on shoot
induction and proliferation were also tested. An average of 21.6±2.87 shoots per explants could be obtained following this
protocol. Rooting was achieved on microshoots using half strength MS medium with 2.0 μM Indole-3-butyric acid (IBA) after
four weeks of culture. The in vitro raised healthy plantlets were successfully established in earthen pots containing garden soil and grown in greenhouse with
>80% survival rate. 相似文献

Walnut has been regarded as a health food that is delicious and nutritious. Both preventive and therapeutic effects of walnut
are well documented. Walnuts are rich in omega-3 fatty acids that are reported to have beneficial effects on brain function.
The present work was designed to evaluate the effects of walnuts on learning and memory in male rats. The effect of oral intake
of walnut was also monitored on food intake. Walnut was given orally to rats for a period of 28 days. Memory function in rats
was assessed by elevated plus maze (EPM) and radial arm maze (RAM). A significant improvement in learning and memory of walnut
treated rats compared to controls was observed. Walnut treated rats also exhibited a significant decrease in food intake while
the change in growth rate (in terms of percentage) remained comparable between the two groups. Analysis of brain monoamines
exhibited enhanced serotonergic levels in rat brain following oral intake of walnuts. The findings suggest that walnut may
exert its hypophagic and nootropic actions via an enhancement of brain 5-HT metabolism. 相似文献
