INTRODUCTION Most secondary abdominal pregnancies happen after spontaneous abortion of tubal pregnancy or ruptured intrauterine pregnancy. However, we presented a case of ruptured secondary abdominal pregnancy after primary laparoscopic treatment of tubal pregnancy. CASE REPORT The ectopic pregnant lesion in the affected tube was thoroughly removed in the primary laparoscopy, and nothing abno...

Binding of human [(125)I]luteinizing hormone to homogenates of luteinized rat ovaries is dependent upon time, temperature, and pH and is saturable. Injection of human chorionic gonadotropin in vivo or addition of unlabeled human chorionic gonadotropin or human or ovine luteinizing hormone in vitro inhibits binding, whereas follicle stimulating hormone or prolactin is without effect. The dissoci...

Overexpression of beta-human chorionic gonadotropin (β-hCG) is frequently associated with germ cell tumours, especially choriocarcinoma. Ectopic secretion of β-hCG by non-small cell lung cancer is exceptional. We present an exceedingly rare case of pulmonary adenocarcinoma that secretes β-hCG. Our patient is a 62-year-old postmenopausal woman, a nonsmoker, who presented with a six-month history...

nancy by the developing embryo after conception and later by the syncytiotrophoblast to prevent disintegration of the corpus luteum of the ovary. hCG also plays a role in cellular differentiation/proliferation and may activate apoptosis (1). hCG is extensively used as a parenteral fertility medication in lieu of luteinizing hormone. hCG is composed of 244 amino acids with a molecular mass of 36...
