Abstract
A primary role of P-glycoprotein (P-gp), encoded by the multidrug resistance type I gene, is to protect against naturally occurring xenotoxics. Recently, the preferential expression of chicken multidrug resistance type I (Cmdr1) was identified in the embryonic gonads during the early periods of development. Here we investigated the expression of Cmdr1 and P-gp in the gonads during embryogenesis, and compared to that in the ovarian follicles of domestic hens (Gallus gallus). As revealed by immunohistochemistry, P-gp was highly expressed in theca cells of mature follicles, whereas the expression was low in immature follicles. Immunohistochemical analysis showed that expression of Cmdr1-type P-gp was very low in embryonic gonads. Cmdr1 mRNA was undetectable in the gonads of 5-day embryos (E5) by RT-PCR, whereas Cmdr1 mRNA was significantly detectable in the developing gonads at E9 and E21. In the testicular tissues, germ cells were distributed along developing seminiferous cords as identified by a specific marker gene, whereas Cmdr1-type P-gp positive cells were observed evenly on testicular tissues. Collectively, it is concluded that Cmdr1 expression is initiated in the chicken ovary and testis after sexual differentiation, but expression of Cmdr1-type P-gp is very low through embryogenesis.

Abstract
The endometrium is one of the most complex tissues; it undergoes dynamic changes in response to implantation and pregnancy processes.An in vitro model may provide a tool for clarifying the complex implantation process. However, there is no suitable in vitro model for investigation of endometrial functions. The spheroid has been utilized in cell biology research because it appears to mimic the morphology and physiology of cells in living tissues and organs, which is unlike conventional monolayer culture. Multicellular spheroids composed of normal adult cells may provide a more useful model for the study of the endometrium. The purpose of the present study was to develop a spheroid composed of rat endometrial stromal (RES) cells as an in vitro model for analysis of endometrial functions. The RES were prepared from rat endometrium at Day 5 of pregnancy. Spheroids were generated using salmon aterocollagen (SAC). The cells were plated on 12-well SAC gels (Imoto Suisan Co.) and cultured in DMEM/F12 containing 10% fetal bovine serum. After the cells reached confluence at Day 7 in culture, SAC gels were digested by collagenase to promote the detachment of RES cell sheets. Then the floating cell sheets were transferred to agarose-coated plates and cultured to form spheroids. The cell sheet shrank and became an aggregated cell mass in a few days; it finally formed a round-shaped spheroid. Diameters of the spheroids were about 516.7 � 28.9 �m at Day 5 after detachment from SAC gels. TUNEL examination of cell viability in the spheroid suggested that no cell was apoptotic until 15 days after cell sheet detachment; TUNEL-positive cells appeared at 20 days. Additionally, no positive staining of proliferating cell nuclear antigen (PCNA) was observed in the spheroids in contrast to strong staining in proliferating monolayer cultured cells. The results of gelatin zymography showed that both matrix metalloproteinases (MMP)-2 and-9 were produced in monolayer culture. However, after the detachment of the cell sheet, the production of both MMPs decreased immediately and could not be detected until 15 days after detachment. In vitro decidualization of the spheroids was induced by arachidonic acid (AA) treatment. RT-PCR analysis showed that typical marker genes for the decidualization, desmin and decidual/trophoblast prolactin-related protein (d/tPRP), were expressed in the spheroids after 2 days of AA treatment, but not in the control groups without treatment. The results of the present study indicate that rat endometrial stromal cells are capable of being regenerated as a spheroid using SAC gels in vitro. Importantly, the present spheroid displays an endometrium-mimicking feature in both structural and functional similarities. The present method is simple and convenient, and therefore provides a new insight into the study of endometrial functions and implantation.

Abstract
1. Phosphate solution, prostaglandin F2alpha and E2, arachidonic acid and arginine vasotocin were injected intrauterinely or intravenously into laying quail hens 6 h before expected oviposition. Following injections, induced ovipositions and secretions of pigment from their shell glands were observed. 2. The effects of intrauterine injection with prostaglandins, which induced oviposition and pigment secretion, were not inhibited by pre-injection of indomethacin. 3. Indomethacin completely inhibited the inducing effects on oviposition and pigment secretion of intrauterine injections with phosphate solution and arachidonic acid. 4. Intravenous injection with arginine vasotocin or prostaglandins also induced oviposition and pigment secretion; indomethacin, however, only inhibited pigment secretion. 5. It is concluded that the effects of prostaglandins on pigment secretion from the shell gland were demonstrated experimentally.

Abstract
Effects of sex steroid hormones on the accumulation of the superficial pigment of the eggshell in the quail shell gland were investigated. In Experiment 1, 10 or 20 mg/100 g BW of aminoglutethimide (AG) was injected s.c. into laying quail hens 10 h before the expected ovulation. Thirty percent of the hens that received 10 mg/100 g BW and 87% of the hens that received 20 mg/100 g BW failed to ovulate. They had significantly (P < .01) lower concentrations of preovulatory plasma progesterone (P) than the control hens and showed significantly (P < .05) low concentrations of plasma estradiol-17 beta (E) and small amounts of the pigment in their shell glands after oviposition of the preceding egg. In Experiment 2, AG (20 mg/100 g BW) was administered s.c. to quail hens 10 h before the expected ovulation, followed by the administration of P (.05, .1, or .2 mg/100 g BW), E (.1, .2, or 1.0 mg/100 g BW), or testosterone (T) (.5 mg/100 g BW). Significant increases in the accumulated pigment 18 h after oviposition of the preceding egg were found when P was injected. However, administration of E and T had no influence on pigment accumulation. These results suggested that P might affect the accumulation of pigment in the quail shell gland.

Abstract
Discussed is a case of a stage IV pure endodermal sinus tumor (EST) of the ovary that was treated with a PVB protocol following cytoreductive surgery. The serum alpha-fetoprotein (AFP) dosage before treatment was 83,546 ng/ml, and a complete clinical response was achieved with the disappearance of pleural effusions, ascites, and normalization of the serum AFP. A second-look laparotomy was substituted by serial AFP determinations and the patient remained free of disease for two years. Recently, complete remissions and long term survivals of patients with a stage I-II disease have been reported, though a prolonged or a complete remission of a stage IV EST of the ovary is still a rarity.
