Laparoscopic Doderlein hysterectomy: a rational alternative to traditional abdominal hysterectomy.

Nearly three of four hysterectomies are performed by abdominal incision. When laparoscopically directed dissection of the uterus adnexae and development of the bladder flap are coupled with a Doderlein vaginal hysterectomy, most of these abdominal procedures can be converted to vaginal procedures. Experience with 167 procedures has demonstrated that this new procedure can be performed safely, effectively, and efficiently. The benefits of less postoperative discomfort, resulting in shorter hospital stays and quicker return to normal activity, coupled with a reduced cosmetic defect, have been clearly demonstrated.

Identification of acetylcholine and propionylcholine in bull spermatozoa by integrated pyrolysis, gas chromatography and mass spectrometry.

Acetylcholine was identified in fertile bull spermatozoa using combined pyrolysis gas-chromatography and mass spectrometry. Bull spermatozoa contain other minor choline esters in smaller quantities than acetylcholine. One of the minor choline esters is possibly propionylcholine. The spermatozoa from infertile bulls exhibited low motility and very low levels of acetylcholine.
