Bactrian camels (63 female female, 8 male male) were used in the breeding season to determine the factors that will induce ovulation. After insemination of semen samples into the vagina, the ovaries were checked for ovulation by rectal palpation. The results indicated that ovulation was induced by the seminal plasma, but not by the spermatozoa, and the(More)
Dexmedetomidine, a highly selective and potent alpha-2 adrenoceptor agonist, reduces halothane anesthetic requirements by over 90% in rats. The present study examined whether dexmedetomidine produces a hypnotic-anesthetic action in rats. Dexmedetomidine induced a hypnotic-anesthetic state in rats characterized by loss of righting reflex at doses greater(More)
Ovulation in the Bactrian camel (Camelus bactrianus) depends upon the ovulation-inducing factor in the seminal plasma; however, little research has been conducted to isolate and identify the factor. The current study attempts to isolate and identify the bioactive fractions from the seminal plasma of Bactrian camel. The seminal plasma was fractionated by(More)
Concentrations of oestradiol-17 beta and progesterone in plasma and milk of the yak before the first oestrus at the beginning of the breeding season and during normal and short oestrus cycles were measured by radioimmunoassay (RIA). Both oestradiol-17 beta and progesterone were maintained at stable, low levels before the first oestrus. However,(More)
OBJECTIVE To analyse the neointimal coverage of sirolimus-eluting stent (SES) and bare-metal stent (BMS) visualised in vivo by optical coherence tomography (OCT). METHODS OCT images were obtained in 26 coronary vessels of 24 patients at 5-93 months after SES or BMS deployment. The short-term BMS group (BMS1) consisted of eight BMS in seven patients at(More)
The anesthetic-reducing property of medetomidine far exceeds that seen with other alpha 2-adrenergic agonists (e.g., clonidine). This study examined whether medetomidine possesses hypnotic-anesthetic actions. Dexmedetomidine (the d-enantiomer of medetomidine) induced loss of righting reflex in rats (i.e., hypnosis) at doses greater than 100 micrograms/kg(More)
The HERA-B Outer Tracker is a large system of planar drift chambers with about 113 000 read-out channels. Its inner part has been designed to be exposed to a particle flux of up to 2 · 10 cms, thus coping with conditions similar to those expected for future hadron collider experiments. 13 superlayers, each consisting of two individual chambers, have been(More)
The stomach is the organ most often chosen for substitution following resection of the oesophagus for carcinoma and this method has given good results. The mode of reconstruction of the alimentary tract in oesophageal cancer patients with previous distal gastrectomy presents a surgical problem. Usually the colon or jejunum is chosen as an alternative for(More)
OBJECTIVE To investigate the value of myocardial performance index (MPI) in assessing LV function in patients with primary hypertension (HP). METHODS We studied 130 patients with HP (mean age 54.9±13.3 years)and 155 healthy control subjects (mean age 52.4±11.6 years). MPI was determined by tissue doppler imaging using the following formula:(More)
