Laparoscopic artificial insemination in dairy sheep with chilled semen stored for up to 26 h

Adult East Freisan crossbred (n = 220) and Chios ewes (n = 105) were divided into four groups and inseminated with chilled semen, which had been stored for 7, 13, 20 or 26 h at 5°C. Unilateral intrauterine insemination (50 x 106 spermatozoa in 0.25 ml) was performed with the aid of a laparoscope. Inseminations were carried out 48 – 52 h after pessary removal (30 mg FGA) without detecting estrus. The lambing rates after intrauterine insemination with chilled semen were found to be similar in East Fresian crossbred (40%) and Chios ewes (30%). Intrauterine insemination with chilled semen stored up to 26 h resulted in similar lambing rates; whereas, fertility of Chios ewes tended to decline with increased holding time of chilled semen. From this study, it is concluded that decreasing the storage time of chilled semen at 5°C improves pregnancy in Chios ewes and that East Fresian crossbred ewe’s conception rates to intrauterine insemination with chilled semen was relatively higher than Chios ewes.Key words: Dairy sheep, chilled semen, time of insemination, lambing rate

Implementation of matrix rhythm therapy and conventional massage in young females and comparison of their acute effects on circulation

Objectives: To examine and compare the effects of massage and matrix rhythm therapy in young women on the peripheral blood circulation. Design: Randomized, double-blind, controlled trial. Setting: Pamukkale University in Denizli, Turkey. Patients: Fifteen healthy women age 19-23 years. Intervention: Matrix rhythm therapy was applied to the left lower extremity for a single 30-minute session. At least 1 week later, massage was applied to the left lower extremity for 30 minutes in a single session. The same physiotherapist applied both sessions. Outcome measures: The blood velocity (cm/s), artery diameter (mm), and blood flow (ml/min) of the popliteal and the posterior tibial arteries were measured with color Doppler ultrasonography. All images were evaluated by the same radiologist. Results: After matrix rhythm therapy and massage application, blood velocity, artery diameter, and blood flow in arteries increased. However, matrix rhythm therapy caused a more prominent increase in the amount of blood flow in the popliteal and in the posterior tibial artery than did massage. After matrix rhythm therapy application, the average increases in the blood flow rates in the popliteal and the posterior tibial arteries were 25.29%±16.55% and 34.33%±15.66%, respectively; after the massage, the increases were 17.84%±17.23% and 16.07%±10.28%, respectively. Conclusion: Matrix rhythm therapy and massage increased peripheral blood flow in young women. Matrix rhythm therapy method resulted in more prominent increases. © Mary Ann Liebert, Inc
