A retrospective study of midtrimester abortions using the intraamniotic instillation of hypertonic saline solution was conducted. All 62 cases admitted to the Ramathibodi Hospital in Bangkok, Thailand for midtrimester abortion in 1980 were terminated by intraamniotic hypertonic saline instillation. The pregnancies were unwanted in 32 (51.6%) of the cases because of family problems, poor socioeconomic status, and deteriorated psychological health. 15 cases (24.2%) were preganancy from rape; 9 (14.5%) had rubella infection during the 1st trimester; and 3 cases (4.8%) were mentally retarded. There was 1 case of renal staghorn calculi post nephrostomy, 1 of multiparity with history of hemophilia in the family, and 1 of failed IUD contraception. The women were between 16-25 years of age in 39 cases, aged 15 or under in 4 cases (6.5%), and over age 35 in 4 cases. In 49 cases (79%) abortion was performed during 16-20 weeks gestation, in 12 cases (19.1%) at 21-24 weeks, and in 1 case at 25 weeks of gestation. The time interval from hypertonic saline instillation to abortion was analyzed in order to evaluate the effect of parity, amount of amniotic fluid withdrawn, and oxytocin augmentation. The mean instillation to abortion time (I-A) was 30.19 +or- 11.25 hours. There were 3 cases which did not receive oxytocin and who spontaneously aborted within 24 hours. Among cases which received oxytocin augmentation, there were 9 who received oxytocin immediately after instillation and 50 who received it 18-24 hours later. The I-A time was 31.22 +or- 11.63 hours in the group that received oxytocin immediately and 31.09 +or- 10.68 in the group receiving it later. There was no statistical difference between the 2 groups. Among the 50 cases which received oxytocin augmentation 18-24 hours later, there was no statistical difference between groups of nulliparity and multiparity. There were 46 cases in which the amount of amniotic fluid withdrawn was noted. In the group in which more than 200 ml of amniotic fluid was withdrawn, the I-A time was 26.81 +or- 7.28 hours. In comparison to the group in which less than 50 ml of amniotic fluid was withdrawn, the I-A time was 28.88 +or- 16.24 hours. There was no statistical difference between the 2 groups. The longer I-A times were found in groups in which 51-1000 ml and 151-200 ml of amniotic fluid were withdrawn. The most common complication was retained placenta (8 cases). There was only 1 case of hemorrhage. There were 2 cases of fever and 1 case of nausea and vomiting. On follow-up of 46.8% of the cases, 2 cases of cervicitis and 3 cases of vaginitis were found and treated with antibiotic suppositories.

Eighty late pregnancy women were randomized into two groups. Misoprostol group and oxytocin group. We observed the different effects of misoprostol and oxytocin on induction, the different effects of misoprostol on induction which was given through rectum or through vagina. The results indicate that the rate of successful induction in misoprostol group is higher than that of oxytocin group, the rate of caesarean section in misoprostol group is lower than that of oxytocin group. There was no significant difference in the durations of misoprostol which was given through rectum or through vagina on induction. It is suggested that misoprostol is more effective on induction than that of oxytocin. We can choose misoprostol given through rectum to prompt delivery in conditions such as premature rupture of membranes and vaginitis.

Endometritis, a major cause of mare infertility arising from failure to remove bacteria, spermatozoa and inflammatory exudate post-breeding, is often undiagnosed. Defects in genital anatomy, myometrial contractions, lymphatic drainage, mucociliary clearance, cervical function, plus vascular degeneration and inflamm-ageing underlie susceptibility to endometritis. Diagnosis is made through detecting uterine fluid, vaginitis, vaginal discharge, short inter-oestrous intervals, inflammatory uterine cytology and positive uterine culture. However, these signs may be absent in subclinical cases. Hypersecretion of an irritating, watery, neutrophilic exudate underlies classic, easy-to-detect streptococcal endometritis. In contrast, biofilm production, tenacious exudate and focal infection may characterize subclinical endometritis, commonly caused by Gram-negative organisms, fungi and staphylococci. Signs of subclinical endometritis include excessive oedema post-mating and a white line between endometrial folds on ultrasound. In addition, cultures of uterine biopsy tissue or of small volume uterine lavage are twice as sensitive as guarded swabs in detecting Gram-negative organisms, while uterine cytology is twice as sensitive as culture in detecting endometritis. Uterine biopsy may detect deep inflammatory and degenerative changes, such as disruption of the elastic fibres of uterine vessels (elastosis), while endoscopy reveals focal lesions invisible on ultrasound. Mares with subclinical endometritis require careful monitoring by ultrasound post-breeding. Treatments that may be added to traditional therapies, such as post-breeding uterine lavage, oxytocin and intrauterine antibiotics, include lavage 1-h before mating, carbetocin, cloprostenol, cervical dilators, systemic antibiotics, intrauterine chelators (EDTA-Tris), mucolytics (DMSO, kerosene, N-acetylcysteine), corticosteroids (prednisolone, dexamethasone) and immunomodulators (cell wall extracts of Mycobacterium phlei and Propionibacterium acnes).
