Abstract

The following describes a modified technique for obtaining 3-microns sections for light microscopic level immunocytochemistry. By combining 20% sucrose with Tissue-Tek OCT embedding compound in a ratio of 2:1, we produced a block that was suitable for cutting 3-microns sections on a conventional cryostat. The 3-microns sections were dramatically improved compared with 10-microns sections cut from tissue embedded in OCT alone, when viewed with both differential interference contrast microscopy (Nomarski optics) and indirect immunofluorescence. The method is simple, uses materials already available, and does not require training in a new technique.

Isolation and Cultivation of Diplonemids.

Marine diplonemids (Diplonemidae and Hemistasiidae), once considered difficult to culture, can now be introduced into stable axenic cultures and grown to high densities. This chapter provides detailed protocols on establishing clonal cultures from environmental cells, their axenization and routine maintenance, as well as instructions on mid- and large-scale cultivation, estimation of cell density, and cryopreservation of selected species.

Laparoscopic ovariectomy for whole human ovary cryopreservation: technical aspects.

OBJECTIVE: To describe the technique of laparoscopic ovariectomy with a view to cryopreservation of a whole ovary with its vascular pedicle. DESIGN: Descriptive study. SETTING: Gynecology research unit in a department of gynecology in a university hospital. PATIENT(S): Women with indications for chemotherapy or radiotherapy who are at high risk of premature ovarian failure. INTERVENTION(S): Laparoscopic ovariectomy for whole ovary cryopreservation in nine patients. MAIN OUTCOME MEASURE(S): Feasibility of laparoscopic ovariectomy for whole ovary cryopreservation and later autotransplantation without delaying chemotherapy. RESULT(S): The whole ovary was successfully removed by laparoscopy and cryopreserved by arterial catheterization in all nine patients. CONCLUSION(S): Ovariectomy with a view to whole ovary cryopreservation for future transplantation may be performed by laparoscopy. Great care must be taken to remove the ovary, together with a large part (> or =5 cm) of the infundibulopelvic ligament, allowing dissection of the ovarian vessels, perfusion with a cryoprotective medium, and cryopreservation for subsequent autografting of the whole ovary. The period of ischemia between ligation of the ovarian pedicle and ovarian cryopreservation must be as short as possible.
