Spiculopteragia asymmetrica is a gastrointestinal nematode frequently found in the abomasum of cervids. During December and February 2010, two red deer were died in Semeskandeh sanctuary in Mazandaran province. Moreover, five live deer from mentioned area were treated by Ivermectin and collected feces of these animals were used for assessment helminthes infection by parasitological methods. Several nematodes were recovered in abomasums and in fecal samples of treated animals. Number of worms recovered from abomasums of two dead animals were 275 (90 male and 185 female) from the first one and 327 (102 male and 225 female) from the second. Based on morphological characteristics nematodes were diagnosed as S. asymmetrica. This is the first report of existence of S. asymmetrica from cervids in Iran.

Bunium persicum (Boiss.) is an economically important medicinal plant growing wild in arid regions in Iran. The essential oil of B. persicum (EOBP) was extracted using hydrodistillation. A total of eighteen compounds, representing 96.14 % of the oil was identified by gas chromatography/mass spectrometry (GC/MS).The main compounds were cuminaldehyde (23.04 %), gamma-terpinene (14.48 %), trans-3-Caren-2-ol (12.51 %), acetic acid (10.90 %) and 1,3,8 -p- menthatriene (7.89 %). The effects of 0.1 to 1000 g mL-1 EOBP on ruminal and abomasal smooth muscle of twenty-four healthy sheep and ileum preparations of six rats were assessed in vitro. Ruminal preparations showed relaxation (P < 0.05) when exposed to 100 - 1000 g mL-1 concentrations of EOBP. In the isolated abomasal preparations, EOBP (0.1 - 1 g mL-1) represented a weak spasmogenic effect followed by relaxation. The spontaneous contraction of abomasal smooth muscles was completely abolished with a high dose (1000 g mL-1) of EOBP. Five-minute incubation with EOBP, significantly (P < 0.05) inhibited Ach-induced contraction in higher doses on both tissues. In contrast, rat ileum only showed dose-dependent relaxation effect, and pre-incubated tissues with EOBP, decreased the Ach-induced contraction. The data indicated that the plant contained spasmogenic and spasmolitic constituents. The results also showed that the EOBP profoundly alters gastrointestinal smooth muscle contraction in a dose-dependent and tissue-specific manner.
