Use of F1 progeny of HolsteinxZebu cross cattle as oocyte donors for in vitro embryo production and gene microinjection.

This study was designed to determine the possibility of using F1 crossbreed cattle (HolsteinxZebu) as donors of oocytes for in vitro fertilization (IVF) and for pronuclear gene microinjection into in vitro-produced embryos. In the first part of the experiment oocytes from Bos taurus (Holstein), Bos indicus (Zebu) and F1 crossbred Bos taurusxBos indicus (HolsteinxZebu) genotypes were inseminated with Bos taurus (Holstein) semen and were allocated for in vitro embryo production using conventional IVF procedures. No differences were observed on the in vitro maturation (IVM) rates between breeds (HolsteinxHolstein:85%, ZebuxHolstein:84% and ZebuxHolsteinxHolstein:88%). Holstein cows yielded the highest number of cumulus oocyte complexes (6.8 per ovary) for in vitro maturation, differing (P<0.05) from ZebuxHolstein and ZebuxHolsteinxHolstein F1 by 5.1 and 5.8, respectively. However, the Holstein breed also yielded the lowest percentage of cleavage (45.1 vs 71.9% for ZebuxHolstein and 65.1% for ZebuxHolsteinxHolstein). Of the 3 genotypes, the hybrid F1 breed was the most efficient source of oocytes for the production of embryos capable of reaching morulae and blastocyst stages (76/250; P<0.001). In the second part of the study, 599 oocytes from the F1 breed were fertilized in vitro, 1 group of 150 oocytes was used for the determination of the optimal pronuclear visualization period. The highest number of oocytes with 2 pronuclei was observed between 24 to 28 h after IVF (27 to 42%). The remaining 399 oocytes were microinjected with a gene construct bearing the bacterial lacZ gene as the reporter for gene expression. Survival of embryos to microinjection was 73.8%, and 45.5% of them (50/110) cleaved in culture. Of the microinjected embryos, 1 out of 50 showed beta-galactosidase activity. These findings indicate that a tropical crossbreed of cattle (ZebuxHolsteinxHolstein) can be used as a source of oocytes for IVF programs and gene microinjection studies.

Electromyographic activity of the gastrointestinal tract following cholecystectomy.

Electromyographic activity of the stomach and small bowel, both in the fasting and fed states, was evaluated in the postoperative period of 8 patients subjected to cholecystectomy. The migrating motor complex (MMC) was recorded on the first postoperative day in 5 patients, on the second day in 2, and on the third day in 1. Vomiting occurred in 1 patient in whom the MMC was recorded only on the third postoperative day. Feeding caused substitution of the MMC by the fed pattern in the stomach and small bowel in all patients. It is concluded from this study that gastric and small bowel motility is normal on the first 2 days of the postoperative period in most patients subjected to cholecystectomy.

Electromyographic evaluation of the gastrointestinal tract in patients with chronic Roux-en-Y limb.

Recently, a Roux-en-Y stasis syndrome was described in a few patients after gastric operations. Although the clinical long term results are usually good, the motility of Roux-en-Y biliary limb has not been evaluated yet. In the present study, we report electromyographic studies of the gastrointestinal tract of two patients with chronic Roux-en-Y hepaticojejunostomy. These two patients provided a unique opportunity to evaluate the electromyographic activity of chronic Roux-en-Y limb in humans after one to five years. Seven pairs of bipolar extracellular electrodes were implanted in the antrum, duodenum, proximal part of the jejunum (15 centimeters proximal to the jejunojejunostomy), distal part of the jejunum (15 centimeters distal to the jejunojejunostomy), ileum, proximal Roux-en-Y limb and distal Roux-en-Y limb. All four phases of the migrating motor complex (MMC) were identified in the antrum and small intestine, including the Roux-en-Y limb, almost simultaneously to phase III in the duodenum. In the other two recordings (25 per cent), there was no relationship between phase III in the Roux-en-Y limb and that in the duodenum. Ingestion of food caused substitution of the MMC by the fed activity pattern in all recordings in the antrum and small intestine, including the Roux-en-Y limb. The findings of the present study indicate that the electromyographic activity of the Roux-en-Y limb may remain normal during fasting and fed states even many years after its creation.
