The material consists of 20 embryos (5-30 mm) and two foetuses (63 mm and 90 mm) collected at whaling stations on Moreton and Norfolk Islands (latitude 27� 11'S. and 29� 5' S. respectively) during late August, September, and early October in 1952-53-54 and 1956. The consecutive series permitted the study of membrane formation and organogenesis. Younger embryos are found in grooves between the folds of endometrium in a constant site in that uterine horn associated with the ovary containing the recent corpus luteum. Older embryos and the early foetus are adapted to lie freely in the uterine fluid, and are devoid of any mechanism for apposition or attachment to the endometrium. Variation in the sequence of the association of the components of the umbilical cord provides suspensory structures for the amnion and yolk sac, and for the embryo a bifid ligament, retained in the early foetus for attachment of the foetal membranes. In the younger foetus the allantoic duct drains the nephric secretion into the uterine cavity. In the older foetus chorionic villi are present. The bifid suspensory ligament forms the major part of the distal region of the umbilical cord. The allantoic duct is reunited with the allantoic sac. Amniogenesis is by folding. During the embryonic period the chorio-amniotic connection forms a suspensory ligament. The yolk sac, attached by a novel ligament to the amnion, is large and functional in the embryo. In the foetus vascular splanchnopleure is present in a tubular form. A rete system develops in the embryo.

Peripartum Period

Plasma steroids (cortisol, progesterone, estrone and estradiol) were studied during the peripartum period in cows with three different types of parturition: unifoetal normal (VUN), unifoetal with retained placenta (VRP), multifoetal with or without retained placenta (VG). In the control group, cortisol rose gradually from 8 ng/ml on day −7 to 11 ng/ml on the day of parturition and thereafter came back to the level of day −7. In the VRP group, cortisol was slightly lower than in the control on day −7 and it did not vary significantly before or after parturition. In the group of cows with multiple births, where retained placenta was encountered in 3/4 cases, cortisol was much higher than in control animals. Plasma progesterone decreased gradually from 5.5 ng/ml to less than 1 ng/ml on the day of parturition in the control group. In the group VRP and VG, it was significantly higher than in the control on the 2 days before and on the day of parturition. The patterns of estrone and estradiol were similar in the groups VUN and VRP until the first day following parturition, but much higher in the cows giving birth to twins. During the postpartum period, the drop in estrogens was much slower in the VRP and VG groups than in the VUN control group. These results suggest that retention of the placenta is not linked with the plasma concentration of cortisol but rather associated with an increased level of progesterone on the day of parturition and that the slower decrease in estrogen levels after parturition would be the result of the persisting attachment of the foetal membranes.

Morphology And Morphometry

Introduction: Placenta is a temporary structure, developed during Pregnancy and discarded at Parturition. Human Placenta is of Discoid and Haemo-Chorial type. It connects the foetus with the mother's womb. It is formed by the contribution of two Individuals - both Mother and Baby. At 1 term four- fth of Placenta is of foetal origin and one- fth is of maternal. Along with Amnion, Chorion, Allantois and Yolk sac, Placenta can also be considered as one of the foetal membranes, which acts as Nutritive and Protective to the developing Embryo. Method: - The present study was done on morphology and morphometry of 150 placentae carried at the Department of Anatomy, Basaveshwara Medical College & Hospital (BMCH), Chitradurga. The placentae were collected with prior ethical clearance and proper consent. Soon after the delivery the placental surface was washed thoroughly under running tap water which were then weighed, tagged and brought to the department of Anatomy, BMCH. The parameters like size, shape and attachment of umbilical cord were noted down. Gross examination was carried out according to the proforma. Result: - The maximum number of placentae belong to the range of 501-600 gms (38.7%). Least placental weight is recorded as 205 gms, showing dispersal pattern. The maximum recorded weight is 835 gms and the average being 491.4 gms. The majority of the placentae are discoid (63.3%). The minimum length recorded is 8.9 cms, maximum as 23.80 cms and the average being 18.3 cms. Conclusion: - Careful examination of Placenta can help in explaining adverse outcomes, their management in subsequent pregnancies and assessment of new born risk.

The B-Lynch uterine suture brace is a relatively new technique used for treatment of postpartum haemorrhage. These uterine compression sutures have achieved hemostasis while preserving fertility in many women and thus their efficacy and safety have been time tested. Very few complications have been reported following B Lynch suture. These include Asherman’s syndrome, hematometra, pyometra, localized areas of uterine necrosis and full-thickness defects in the lower uterine segment or uterine fundus and erosion of uterine wall. Herewith, reporting a case of 23-year-old woman who underwent cesarean section for breech presentation. She had atonic PPH for which uterine artery ligation was done along with B-lynch suture. She developed uterine necrosis for which hysterectomy was done. Microsections showed that endometrial cavity was filled with gangrenous slough extending to variable extent in myometrium and cervix.

Abstract Septum resection using hysterescopy is safe, rapid and efective, but some late complication of it may be seen as uterine rupture or dehiscence of uterine wall during pregnancy due to myometrial damage. We present a case of recurrent large uterine fundal dehiscence conscecutive to cesarean section in a patient who had previously undergone a uterine septum resection. The patient was a 35-year-old who presented at 39 weeks of gestation (Gravida 2, Parity 1) and was admitted for an elective cesarean section. Her reproductive history included a septum resection which resulted in uterine perforation, and one previous cesarean section in which a large fundal defect was found and repaired. Then the examination had shown an aproximately 5 cm large uterine fundus defect including all three layers of uterus which had been repaired. Perforation or excessively deep incision of uterine fundus during hysteroscopic metroplasty may cause chronic weakness of the uterine wall especially at fundal localization. Our case was an incidental uterine wall dehiscence during cesarean section. Patients with an uterine septum resection history should be followed up carefully for uterine rupture during pregnancy.
