This experiment was conducted to determine the reproductive performance of Arabian ewes treated with short and long-term progesterone devices in addition to low doses of equine chorionic gonadotropin (eCG) during the ANOESTRUS SEASON. A total of 36 ewes were divided into three groups: in group I vaginal sponges (60 mg medroxy progesterone acetate; (MAP)) were applied and removed after 6 days; in group II, vaginal MAP sponges were removed 12 days following insertion, while group III served as control group. The first two groups were intramuscularly injected with of 300 IU eCG, following sponge removal. Parameters such as oestrus response rate, time to onset of oestrus, duration of oestrus, pregnancy, lambing and fecundity rates were evaluated. Blood samples were collected one day before sponge insertion and two days after sponge insertion and on day of oestrus. There were significant differences between the group I and II with control group regarding the plasma estradiol and progesterone levels. There were no significant differences in oestrus response, time to onset of oestrus, pregnancy, lambing and fecundity rates between groups I and II (P>0.05). However, differences were significant when these two treatment groups were compared with the control group. In group I, duration of oestrus was significantly higher than group II (P<0.05). In addition, other factors in group I was numerically greater than group II (P>0.05). It was concluded that short-term sponge treatment (6 days) had better performance when compared with the long-term sponge treatment (12 days) in Arabian ewes.

Postpartum anestrous is one of the most important problems in the dairy industry in the world and especially in Iran. The objective of present study was to compare the efficacy of two hormonal programs for recycling of postpartum anestrous cows. For this reason, 230 Holstein cows from 4 similar dairy herds (with totally 2560 cow and unique management and feeding system) located on the suburb of Tabriz (North-west of Iran) were examined during April 2012 to August2013. These cows showed no visible oestrus signs until the minimum 60 days postpartum. Clinical examinations were performed twice, with a 10 days interval, and blood samples for progesterone analysis were collected simultaneously with every rectal palpation. Based on progesterone values and clinical examinations only cows with lower progesterone levels (P4<2ngr/ml) at both sampling and nonfunctional ovaries (at two consecutive examinations) were randomly allocated into three groups: A, B (n=100) and C (n=30). Cows in group A were administered a combination of Gonadotropin releasing hormone (GnRH) on day 1 and prostaglandin F2alpha on day 8; cows in group B were administered 125 mg of progesterone for 8 days, whereas cows in the control group C were given placebo. Subsequently all cows were examined for signs of estrus and performed artificial insemination on two consecutive estrus following treatment. In groups A & B the rates of observed oestrus, first service conception rates and second service conception rates were 5% vs. 68%, 60% vs.25% and 100% vs.64.7% respectively. In the group of C, cows were not observed in estrous. Significant differences were observed between groups in all fields (p£0.01). Thus based on the current study it can be concluded that for recycling postpartum ANOESTRUS cows, progesterone therapy is the treatment of choice.

Bell’s palsy is a relatively common disease characterized by the sudden onset of unilateral facial paralysis. Using a centralized system that contains demographic data, the authors estimated rates, trends, and demographic risk of Bell’s palsy during a 2-year period. There were 140 incident cases of Bell’s palsy among patients referring to private clinics (a total of 6500 patients). The crude incidence rate was 2.15%. Incidence rates were high in an age range between 20-30 years and were equal among females and males. Incidence of BP was higher in cold SEASON than warm ones and higher in cold regions. The results are consistent with hypotheses regarding viral etiologies (e.g., reactivation of herpes simplex) of Bell’s palsy in which cold can activate this virus.

White shore is always seen in spring, summer, fall and winter around Urmia lake, but this whiteness is not snow, it is crystallized salt. The lake is located between East and West Azerbaijan in the northwest of Iran. Urmia lake is about 4500-6000 square kilometers and is the 20th largest lake in the world.
