Abstract

A 42-year-old woman with recurrent bilateral endometrial ovarian cystoma presented with fever and pelvic pain caused by a tubo-ovarian abscess (TOA), which was resistant to several varieties of intravenous and oral antibiotics for 2 weeks (Case 1). Computed tomography (CT)-guided diagnostic aspiration for a rapid enlarged right ovarian cystoma through a transabdominal route confirmed that it had developed into a TOA. Subsequent percutaneous abscess drainage (PAD) and irrigation for 3 days were successful. One-year follow-up revealed no recurrence of TOA. A 58-year-old woman with recurrent cervical cancer after external radiation therapy (RT) presented with fever, confusion and tremor caused by pyometra (Case 2). Since transvaginal drainage was impossible due to cervical os obstruction, the patient had undergone CT-guided transabdominal PAD and irrigation for a month. Thereafter, the clinical findings improved and a tracheloplasty was performed to prevent recurrence. CT-guided PAD may be a useful treatment option for gynecologic abscess as a diagnostic aspiration, a temporizing procedure until surgery, or an alternative surgery.

Abstract

Diapause pupae of Papilio xuthus show color polymorphism, represented by diapausegreen, orange, and brownish-orange types that are each associated with specific pupation sites. We investigated the role of the site of pupation on the induction of the development of orange types (or brownish- orange types), and the endocrine mechanism underlying the control of color polymorphism in shortday pupae. All short-day larvae of the wandering stage developed into orange or brownish-orange type pupae when they were placed in rough-surfaced containers after gut-purge. Utilizing a pharate pupal ligation between the thorax and abdomen, the endocrine mechanism underlying the control of color polymorphism was shown to involve a head-thorax factor (Orange-Pupa-Inducing Factor: OPIF) that induced orange types in short-day pupae. OPIF was bioassayed using the ligated abdomens of short-day pharate pupae. OPIF was extractable with 2% NaCl solution from 5th-instar larval ganglia complexes following the mesothoracic complex (TG2,3-AG1-7), but it could not be extracted with either acetone or 80% ethanol solution. OPIF may not exist in the brains of day-0 pupae or in brain-subesophageal ganglion and prothoracic ganglion complexes of 5th-instar larvae. The short-day pharate pupae responded to OPIF in a dose-dependent manner. [ABSTRACT FROM AUTHOR]

20. [Estrogen and bone metabolism].

Author

Ohama K and Kodama I

Abstract

The increased rate of bone remodeling that follows loss of estrogen can be accounted for by increased osteoclastogenesis (formation of bone-resorbing cells) and osteoblastogenesis (formation of bone-forming cells). And, estrogen replacement provides an effective prevention of postmenopausal osteoporosis. Genomic and non-genomic actions of estrogen regulate bone remodeling.
