To evaluate the kinetics of the in vitro maturation of buffalo oocytes, 1.619 oocytes with compact cumulus oophorus were cultivated in different treatments: T1 - TCM 199 with 10% of bovine foetal serum (BFS) (basic medium); T2 – Medium basic and granulosa cells (GC); T3 –Basic medium, GC, 10 IU of eCG and 10 IU of hCG; T4 – Basic medium , 10 IU of eCG, 10 IU of hCG and 1 µg 17b-estradiol / ml, in times 14 to 17 h, 20 to 22 h, 23 to 25 h, 26 to 28 h, 29 h and 32 h of cultivation in CO2 incubator at 5% and temperature of 38,5ºC. In the treatment 1, it was observed that 81,83%, 69,61%, 65,88%, 60,28%, 64,98% and 67,67% of the oocytes restarted the meiosis; with the treatment 2, rates of oocytes restart of the meiosis were of 76,06%, 72,06%, 69,78%, 68,12%,74,97% and 89,96%; with the treatment 3 rates were of 83,59%, 78,86%, 77,49%, 82,4%, 72,92% and 81,06% and with the treatment 4 the rates were of 95,0%, 91,82%, 93, 17%, 91,65%, 92,09% and 74,99% in the times from 14 to 17 h, 20 to 22 h, 23 to 25 h, 26 to 28 h, 29 h and 32 h of culture, respectively, could be concluded that the supllemented medium provides larger rates of restarted of the meiosis in smaller time, as well as the increase in the time of cultivation it can take to largest rates of degeneration.

Stem cells from adipose tissue improve the time of wound healing in rats
(Sociedade Brasileira para o Desenvolvimento da Pesquisa em Cirurgia, 2016-12) OHASHI, Camila Melo; CALDEIRA, Fabio Alves Morikawa; FEITOSA JUNIOR, Denilson José Silva; VALENTE, André Lopes; DUTRA, Paulo Roberto Witter; MIRANDA, Moysés dos Santos; SANTOS, Simone do Socorro Damasceno; BRITO, Marcus Vinicius Henriques; OHASHI, Otávio Mitio; YASOJIMA, Edson Yuzur
PURPOSE: To evaluate the Adipose Stem Cells (ACS) therapy efficacy on the time and quality of wound healing process in rats. METHODS: Nine male Wistar rats were randomly distributed into three groups I) 7 days of healing; II) 14 days of healing; III) 21 days of healing. Four incisions were made on the dorsal surface of each rat and then treated with intralesional ACS, meloxicam, and no treatment and ACS+meloxicam. Macroscopic evaluation was measured by percentage of healing and histopathological by hematoxylineosin was performed. RESULTS: All groups have the wound reduced during the three weeks (p<0.001) and after 14 days of healing had greater reduction than others. Wounds treated with ASC had accelerated healing in relation to no treatment and only meloxicam (p<0.001), excepting the ASC+Meloxicam that was similar (p=0.13). There was no difference in histopathological analysis between lesions. CONCLUSION: Adipose stem cell have benefits in reducing time of healing of experimental model of wound in rats, observed 7 days of after application.
